Synthetic fibers and blended textiles have the minimum shrinkage rate, followed by woolen fabrics, hemp fabrics, cotton fabrics, silk fabrics have a larger shrinkage, while the largest ones are viscose fiber, rayon, rayon fabrics.
From an objective point of view, cotton fabrics have more or less the problem of shrinkage and fading, with the key being the finishing afterwards. So the general home textile fabrics are pre-shrinking processed.
It is worth noting that pre-shrinkage processing is not tantamount to no shrinkage, but instead means that the shrinkage rate is controlled within GB standard of 3%-4%. Fabrics, especially natural fiber fabrics, will shrink. Therefore, it is important to know the shrinkage rate of the fabric, in addition to the quality, color and pattern of the fabric, when purchasing fabrics.

I. The effect of fiber and knitting shrinkage
When fibers absorb water, a certain degree of swelling occurs. Usually, the swelling of fibers is anisotropic (except nylon), which means that the length is shortened and the diameter is increased. The difference between the length of the fabric before and after washing and the percentage of its original length is usually called the shrinkage rate. The stronger the water absorption capacity, the more intense the swelling, the higher the shrinkage rate, the worse the dimensional stability of the fabric.
The length of the fabric itself is different from the length of the yarn (thread) used, and the difference between the two is usually indicated by the knitting shrinkage rate.
Knittng shrinkage (%) = [yarn(thread) length – fabric length] / fabric length
After the fabric is put into the water, the fabric length is further shortened due to the swelling of the fiber, resulting in shrinkage. Fabric knitting shrinkage rate is different, so is the shrinkage rate. The fabric’s own structure and knitting tension is different, so its knitting shrinkage rate is also different. With lower knitting tension, the fabric is tight and thick, and the knitting shrinkage rate is large, and the shrinkage rate of the fabric is low; with higher knitting tension, the fabric is light and loose, and the knitting shrinkage rate is small, and the shrinkage rate of the fabric is high. In the dyeing and finishing process, in order to reduce the shrinkage rate of the fabric, often use the pre-shrinkage process to increase the weft density, to improve the knitting shrinkage rate in advance, so as to reduce the shrinkage rate of the fabric.

II. The causes of shrinkage.
(1) When spinning，knitting and dyeing, the yarn and fiber in the fabric are stretched or deformed by the external force, and the yarn and fiber and fabric structure produce internal stress in the static dry relaxation state, or static wet relaxation state, or in the dynamic wet relaxation state, full relaxation state, the release of different degrees of internal stress, so that the yarn，fiber and fabric back to the initial state.
(2) Different fibers and their fabrics have different degrees of shrinkage, mainly depending on the properties of their fibers – hydrophilic fibers have a greater degree of shrinkage, such as cotton, linen, viscose and other fibers; hydrophobic fibers have a lower degree of shrinkage, such as synthetic fibers.
(3) When the fibers are moistened, they swell under the influence of liquid, increasing the diameter of the fibers, forcing the radius of curvature at the interweaving point of the fabric increases, resulting in a shortening of the length of the fabric. For example, cotton fibers in the role of water expansion, cross-sectional area increased by 40 ~ 50%, the length increased by 1-2%, while synthetic fibers are shrinkage to heat, such as boiling water shrinkage, etc., generally about 5%.
(4) Under the heat conditions, the shape and size of the fiber change and shrink. After cooling down, it also cannot return to the initial state, known as fiber thermal contraction. The percentage of length before and after thermal contraction is called thermal contraction rate. Generally, it is measured by 100℃ boiling water contraction test. It is also measured by hot air, the percentage of contraction in hot air at over 100℃, and also by steam, the percentage of contraction in steam at over 100℃. Fibers also perform differently under different conditions such as internal structure, heat temperature and time.For example, the boiling water shrinkage of processing polyester staple fiber is 1%, while vinylon is 5%, and the team shrinkage of polyvinyl chloride is 50%.
There is a close connection between fiber processing and the dimensional stability of its fabric, which provides some basis for the design of the post-process.

III. The shrinkage rate of common fabrics
Cotton 4% – 10%.
Synthetic fiber 4% – 8%.
Cotton-polyester 3.5% – 5 5%.
White cotton fabric 3%
Blue Print Cloth 3-4%
Poplin 3-4.5%
Printed cotton fabric 3-3.5%
Twill 4%
Denim 10%$
Synthetic cotton 10%.

IV. Factors affecting the shrinkage rate
1. Raw materials
Fabric raw materials are different, so the shrinkage rate is varied. In general, the moisture-absorbent fibers swell after immersion, the diameter increases, the length shortens, and the shrinkage rate is higher. For example, some viscose fiber water absorption rate of up to 13%, while the synthetic fiber fabric moisture absorption is poor, and its shrinkage rate is low.
2. Density
The density of the fabric is different, and its shrinkage rate is also different. Such as warp and weft density is similar, its warp and weft shrinkage rate is also close. If the fabric warp density is larger than the weft density, the warp shrinkage is large, and vice versa, if the weft density of the fabric is larger than the warp density, the weft shrinkage is large.
3. Yarn thickness
With different fabric yarn thickness, the shrinkage rate is also different. Fabric with thick yarn count has a higher shrinkage rate, and fabric with fine yarn count has a lower shrinkage rate.
4. Manufacturing tech
With different production tech of fabrics, the shrinkage rate is also different. Generally, in the process of knitting and dyeing fabrics, the fibers are stretched multiple times, and the processing time is long. The shrinkage of the fabric with higher tension applied is higher, and vice versa.
5. Natural plant fibers (such as cotton, hemp) and recycled plant fibers (such as viscose) are easier to absorb moisture and swell compared to synthetic fibers (such as polyester, acrylic), so the shrinkage is higher. Wool, on the other hand, is prone to matting due to the scale structure of the fiber surface, which affects its dimensional stability.
6. Fabric structure
In general, the dimensional stability of woven fabrics is better than knitted fabrics; high-density fabrics are better than low-density ones.
In woven fabrics, the general shrinkage rate of plain fabrics is lower than that of flannel; and in knitted fabrics, the shrinkage rate of plain knitted structures is lower than that of ribbed fabrics.
7. Production process
As the fabric is dyed, printed and finalized, it will inevitably be stretched by the machine, thus there is tension on the fabric. However, the fabric is easy to release the tension after being exposed to water, so we will find the fabric shrinks after laundering. In the practical process, we generally use pre-shrinkage to solve this problem.
8. Washing and care process
Washing care includes washing, drying, and ironing, and each of these three steps affects the shrinkage of the fabric. For example, the dimensional stability of hand-washed samples is better than that of machine-washed samples, and the temperature of the wash will likewise affect its dimensional stability. In general, the higher the temperature, the less stable it is. The way the sample is dried also has a greater impact on the shrinkage of the fabric.
Commonly used drying methods are drip drying, flat laying, hung drying and rotary drying. Wherein the drip drying method has the least effect on the size of the fabric, while the rotary drying has the greatest effect, and the remaining two are moderate.
In addition, a suitable ironing temperature based on the composition of the fabric can also improve the shrinkage of the fabric. For example, cotton and linen fabrics can be ironed at high temperatures to improve their size shrinkage. But not the higher the temperature is better, for synthetic fibers, high temperature ironing can not improve its shrinkage rate, but will have damage to its performance, like fabric became hard and fragile.

01
Quick-dry

Quick-dry fabrics are common in sportswear and are double-layered fabrics, with a non-absorbent, but porous, chemical fibre layer close to the body and an absorbent cotton blended layer on the outside. It is generally more of a chemical fibre and polyester fabric, which is more comfortable as the garment does not stick to the body after sweating.
Pros: Super volatile and absorbent, dissipates moisture and keeps you warm, keeps your skin dry and fresh, and works better in protecting against wind, rain and moisture.
Cons: Quick-drying fabrics that contain 100% polyester are not in a comfortable state as far as the human body feels when wearing them.

02
Audel Fabric

Audel fabric is a high-quality fibre made from vegetable protein fibres, which are then spun through a special process, and cotton and this vegetable protein fibre are woven together to form the fabric. It is an environmentally friendly textile fabric.

Pros: good moisture absorption, moisture conductivity, elasticity, soft and breathable, draping and airy features, light and thin texture, smooth, not easy to shrink, easy to wash, quick drying.
Cons: the fabric is a natural fibre fabric, which is expensive and easy to buy as a counterfeit.

03
Modal Fabric

Modal is a cellulosic fibre, which, like rayon, is a pure synthetic fibre. It is made from wood pulp produced in the bush forests of Europe and then subjected to a special spinning process, and is now mostly used in the production of underwear.

Pros: soft touch, strong moisture absorption, bright colours, good drapability, T fabric has a natural wrinkle resistance and non-ironing feature.
Cons: poor fabric stiffness, easy to pill, high cost.

04
Cationic Fabric

Cationic fabrics are 100% polyester fabrics, generally made using cationic yarns in the warp direction and ordinary polyester yarns in the weft direction, sometimes a blend of polyester and cationic component fibres is used to achieve a better imitation of hemp.

Pros: Soft to the touch and comfortable to wear. It is very absorbent and has a low dye difference, which makes it particularly suitable for sportswear.
Cons: There are basically no disadvantages to cationic fabrics, except that they are more expensive to produce than polyester fabrics and are easily replaced by yarn-dyed fabrics.

05
Lycra Fabric

Lycra is a fabric made from spandex (short for Spandex polyurethane).

Pros: It is stretchy and does not deform easily. Adding Lycra to the fabric enhances the elasticity of the fabric and it can be used in combination with a variety of different fibres without changing the appearance or texture of the fabric. The fabric is very soft.
Cons: Lycra must be blended with other fibres, otherwise it is not possible to produce a final fabric.

06
Bamboo Fibre

Bamboo fibre fabric is a new type of fabric made from bamboo by a special process and woven from bamboo fibre. It is a truly natural and environmentally friendly green fibre.

Pros: smooth and soft warmth, moisture absorption and breathability, antibacterial, anti-UV, warm in winter and cool in summer, natural beauty effects of bamboo, natural anti-mite, anti-odour and anti-insect features create negative ion, natural health care, green and eco-friendly.
Cons: short lifespan; after a period of use, the cotton coils tend to shed and lose their original softness and warmth, becoming dry and hard; breathability and instant absorbency gradually diminish after use.

07
Viscose

Viscose fabric is a fabric made of viscose fibre by weaving, with soft, smooth, breathable, anti-static and gorgeous dyeing features.

Pros: soft, smooth and cool to the touch, breathable. Excellent anti-static effect, no feeling of adhesion to the body and therefore very smooth, particularly suitable for sportswear.
Cons: easy to deform, heavy feel of viscose fibres, poor elasticity and easy to crease and not very flexible.

08
Milk Fibre

Milk fibre is made from milk protein with a softener to make a milk pulp, which is then spun into milk protein fibre through a wet spinning process and scientific treatment, and further spun into milk yarn that can be woven knitted into fabric.

Pros: good warmth, moisture conductivity and colouring, soft and skin-friendly, wear-resistant and anti-pilling, not easily moulded.
Cons: milk fibre is slightly less breathable and sweat-absorbent.

09
Nylon

Nylon is the scientific name for polyamide fibres, a generic term for polyamide fibres produced in China. Nylon fabrics are very hard-wearing and durable, absorb moisture well and are lightweight fabrics.

Pros: excellent elasticity and elastic recovery, the highest abrasion resistance of all types of fabrics, many times higher than other fibre fabrics of the same type, therefore, its durability is excellent.
Cons: easy to deform under small external forces, so its fabric is easy to become wrinkled while wearing. Heat and light resistance are poor. Care must be taken in the process of laundering and maintenance to avoid damage to the fabric.

Yoga is a rather stretchy and restorative sport. It is about the harmony between man and nature, so you can’t be sloppy when it comes to yoga outfits. If you choose a garment with a bad fabric, it may tear when you do stretching exercises, and it may be deformed and a wardrobe malfunction might unfortunately occur. So you must pay attention to what fabric you are wearing for yoga.

You’ve probably seen the words “recycled polyester” or “RPET”printed on the labels of everything from pants to shirts to bags. It means that the fiber is made from waste material, like waste PET bottle, not from the virgin fiber from the petroleum in general.

What Is Recycled Polyester?

RPET is the short name often used for recycled polyethylene tetraphyte (PET), normally we also called Recycled Polyester.
The PET (Polyethylene terephthalate) is a common plastic, which is widely used in water bottle or other drink bottle and polyester fiber used in clothes and industry.
The recycled polyester fiber is not better than virgin polyester fiber and it brings harder control when in producing. However, with people’s importance in environment protection, the recycled polyester fabrics become more and more popular.

▲the recycled polyester raw material- post-consumer PET bottle

Why Choose Recycled Polyester?

In short, RPET takes plastic that has already been created, usually plastic bottles, and chops the bottles into tiny flakes. These flakes are then melted to separate the core PET ingredient inside of the bottle. This PET can then be used to make anything from a sweater to another plastic bottle. Not only is up to 50% less energy used than making PET from scratch, but by using existing bottles already created, it ensures these bottle don’t end up in landfill. It also means we can leave the planet as it is: rather than obtaining the core ingredient via the highly damaging process of crude oil primary extraction, we instead make use of a product in abundance that may otherwise have directly contributed to landfill.
PET bottle is not easy to degrade and now we can transfer the rubbish to another resource.

How To Make The Recycle Polyester Fabric

▲recycle polyester fabric process

Any Different In Producing Fabric

The recycled polyester fabric is made of recyceld polyester fiber.  The recycled polyester spandex fabric is making of recycled polyester fiber and conventional spandex. It has the same process: knitting, dyeing, setting and finishing and print if needed. The only different is polyester fibers change to same specification in recycled.
The recycled polyester fiber is from waste and polymerize again, so the fiber is easy to broken and when dye the shiny also less than virgin one. We need adjust technique method, like slow the speed and use better dye material.

GRS Certificate In Trading

▲GRS certificate

When use the recycled polyester, the customers always request the recycled label or GRS certificate. The GRS certificate can ensure the fabric production chain is pure and confirm the producers use the right recycled fibers by TC (TRANSACTION CERTIFICATE).
We will apply TC for each order for customers.

Choose the good quality in main point

In the current times, the increasing people prefer keep thin figure by wearing the shapewear. It is analyzed that the global shapewear market is about USD 9 billion to 10 billion. The shape wear factories are new founded in China, Vietnam, Bangladesh etc.

This article is some advice to choose shape wear in some important points

▲4 Way Stretch Shapewear

1. Stretchable

Stretch is believed to be one of the most important elements for choosing the shapewear.

4 Way stretch are treated as the basic quality request to a shapwear.

The higher stretchability will contribute to good performance to show the customers’ proportioned figure.

The higher spandex composition and the higher weight are widely in favor in the shapewear producing.

2. Breathable

People will often take sports when wearing the shapewear. It will bring some uncomfortable feeling if much sweat occurs. That’s why most of majority of the shapewear fabrics have the breathable dry fit function.

3. Weight

The weight of shape wear is normally in 160-350 GSM. This weight will keep the fabrics or the finished shapewear in excellent in various aspects.

4. Warm keep

Some customers will prefer to wear the shape wear in winter, we should consider the warm keep in fabrics development. The main points to solve the problem are

i) make fabric more heavy, higher weight

ii) make the fabric higher density, even water- repellent to keep wind away

iii) make the fabric brushed to keep warm

5. Antimicrobial

The shapewears are normally skin dressing, while the it always inpoured much sweat. The shape wear has much more microbial than other clothes. The antimicrobial function is high cost, but necessary.

A Decade High Price of Spandex, What are reasons behind?

Since this year, commodity prices rising excessively fast has brought impact on China’s downstream entities, which has aroused great concern from all sides. The executive meetings of the State Council have repeatedly emphasized the deployment of a good job to ensure the supply and stabilize the price of commodities, and has achieved initial results. However, with the improvement of the global epidemic and the gradual recovery of oil demand, domestic and foreign crude oil futures prices rose in tandem. As a result, the chemical fiber raw material market remained generally firm.

The spandex, known as “MSG” in the textile industry, has recently continued to rise in price and went viral, causing much attention.

Data show that, at present, spandex stock supply is still tight in Shandong, Zhejiang, Jiangsu, Fujian and other places, continuing to hand over the previous orders. Some manufacturers are not taking new orders for the time being, mainly supplying quality customers. In terms of price, on 12 July, the price of 40D spandex was RMB 77,000/ton, up RMB 1,600/ton from the price at the beginning of July, up RMB 9,400/ton from 3 months ago, up by 13.91%, and up by 156.34% from the average price in the same month last year. 40D spandex price as a whole is on an upward trend.

Currently, the price of spandex has reached new heights in 10 years. A practitioner of the industry for many years lamented that over the years, spandex prices are also fluctuating, but an increase of more than RMB 60,000/tonne is rarely the time. This ongoing round of price increase is unprecedented.

So, what has led to the current round of spandex price increases? What will happen to spandex prices in the future?

Tight supply and demand-A dynamic application range for spandex

As consumer attitudes change and consumer demand grows, consumers demand more and more sports and leisure apparel and have higher and higher functional requirements for clothing. Fabrics containing spandex are widely used in professional sportswear, swimwear and protective clothing due to their excellent elasticity, acid and alkali resistance, sweat resistance, seawater resistance and abrasion resistance, making spandex stretch fabrics increasingly popular in the market. And this spandex price increase, can not be separated from the support of the demand. The shortage of spandex supplies in the market and the factory low stock drive its price further up.

” A very important reason for the current round of spandex price rise is the tight supply and demand.” spandex industry analyst Gong Yuqian of Zhuo Chuang Information told the correspondent of “Securities Daily”. On the demand side, post-pandemic domestic textile and clothing demand recovery plus the transfer of foreign orders have driven spandex demand to increase. On the supply side, due to the low price of spandex in the past few years , the industry accelerated reshuffling, and many old maturerers of old and low capacity were eliminated from the game. The supply and demand pattern of spandex was changed from overcapacity to tight supply.

The growth on the demand side was clearly felt by spandex companies. “After the pandemic, we can clearly feel the significant increase in demand for spandex from customers in the medical field such as mask ear belts and protective clothing, while the market in this part was previously small.” Liu Jianning of Taihe New Material securities department told the Securities Daily correspondent, that the pandemic led to more time spent at home by the masses and increased health awareness, leading to an increase in the application of spandex in home sportswear and casual sportswear, as well as more adequate orders in the textile industry, all leading to rapid growth in spandex demand.

In addition to the growth in domestic demand, affected by the COVID-19 pandemic, exports from the garment industry in Southeast Asian countries shrank severely and some orders for textiles were transferred to China, further pushing up the demand for spandex. Customs statistics show that in September 2020 ~ May 2021, China’s cumulative exports of textiles and garments amounted to US$216.725 billion, an increase of 13.74% year-on-year, of which the cumulative exports of textiles amounted to US$105.230 billion, an increase of 6.47% year-on-year; the cumulative exports of garments amounted to US$111.495 billion, an increase of 21.56% year-on-year. In particular, from January to May this year, China’s cumulative exports of garments amounted to US$56.612 billion, an increase of 48.33% year-on-year.

“The growth in demand for spandex can also be proven from the starting rate of downstream weaving machines.” Gong Yuqian told Securities Daily. As of June 24, the start rate of circular and warp knitting machines in Zhejiang was 61% and 87% respectively, an increase of 11 and 17 percentage respectively compared to the same period last year. In the first half of this year, the start rate of circular and warp knitting machines was 53% and 72% respectively; while in the same period of 2020, affected by the pandemic, the start rate of circular and warp knitting machines was only 33% and 34%.

“In addition, the rise in the price of raw materials is also an important factor in the price increase of spandex.” Gong Yuqian said. During the the first half of this year, the average price of PTMEG, the main raw material for spandex, reached 34,515.5 yuan per tonne, up by 99% compared to the same period last year, and the average price of MDI, another raw material, also rose by 55%, the rising cost is an important factor in the price increase of spandex.

Continued strong demand from downstream-Leading companies see sharp rise in profits

In the general background of the positive market, the market performance of spandex manufacturers is also very impressive. One of the leading domestic spandex enterprises, Taihe New Material announced a half year performance forecast on the evening of July 6. The company is expected to achieve a net profit attributable to shareholders of the listed company of 400 million yuan to 450 million yuan in the first half of 2021, an increase of 222.45% to 262.76%. The announcement said that since this year, the demand for spandex industry has continued to be strong. The concentration of production capacity has increased significantly. The price of spandex has continued to rise, and the profit level has increased significantly year-on-year.

▲The Commodity Price Increasing

On July 9, Huafon Chemical (002064.SZ) released its 2021 semi-annual performance preview, saying the company expects to achieve a net profit attributable to shareholders of the listed company of about 3.6 billion yuan to 3.9 billion yuan in the first half of the year, an increase of 441.31% to 486.42% over the same period of the previous year.

Financial data show that in 2020, the company achieved operating revenue of 14.724 billion yuan, a slight increase of 6.81% year-on-year; achieved net profit attributable to shareholders of the listed company was 2.279 billion yuan, an increase of 23.77% year-on-year, after deducting non-recurring gains and losses its earning was 2.194 billion yuan, up by 348.63% year-on-year from the previous year. During the first quarter of 2021, its operating revenue increased by 120.77% to RMB 5.794 billion, and net profit attributable to shareholders of the listed company rose by 501.67% year-on-year to RMB 1.64 billion.

It is estimated that Huafon Chemical’s profit in the first half of the year exceeded the annual profit of 2020. Meanwhile, a rough estimate shows that in the second quarter of this year, the company is expected to achieve a net profit attributable to shareholders of the listed company of approximately RMB 1.96 billion to RMB 2.26 billion, an increase of 19.51% to 37.8% over the first quarter on a sequential basis.

Regarding the performance growth, Huafon Chemical explained that during the reporting period, the industry downstream demand recovered and the boom continued to rise. The yield, sales and price of the company’s leading products in the half-year of 2021 have increased substantially compared with the same period of the previous year. At the same time, the company has strengthened cost control and effectively resolved the fluctuation of raw material prices. The company’s overall gross profit margin increased significantly and achieved a greater year-on-year increase in operating conditions and earnings.

On July 12, Xinxiang Chemical Fiber released a performance preview. The company is expected to achieve a net profit of 710 million to 760 million yuan in the first half of the year, an increase of 2394.14% to 2569.79% over the same period of the previous year, the net profit of 28,466,700 yuan in the same period of the previous year. Although somewhat affected by the low baseline for the same period in 2020, the net profit of more than 700 million yuan in the first half of the year is substantial.

“During the reporting period, influenced by the sustained growth of the basic demand of the spandex industry, the price of the company’s major product, spandex fiber, increased significantly compared with the same period of the previous year. sales volume increased significantly and the gross profit margin of the spandex business increased significantly. The company’s half-year results increased considerably compared with the same period of the previous year.” Xinxiang Chemical Fiber performance preview noted.

Industry inventories continue to remain low-Spandex prices may reach new record highs

China is currently the world’s largest producer and consumer of spandex. According to the 2020 Spandex Industry Chain Annual Report published by the China Chemical Fiber Information Network, global spandex production capacity was 1.223 million tonnes in 2020, of which China’s domestic production capacity accounted for approximately 71%.

▲The Production Capacity Of Spandex Fiber in China

Spandex has seen such a strong increase in price this year, mainly because spandex production capacity is growing at a slower rate than the growth in demand. Spandex production capacity grew from 165,000 tonnes in 2004 to 785,500 tonnes in 2018; by 2019 China’s spandex production capacity reached 849,500 tonnes, an increase of 8.1% year-on-year; last year in 2020 China’s spandex production was 871,500 tonnes, an increase of only 22,000 tonnes, or 2.59% year-on-year.

And in recent years, China’s apparent consumption of spandex rose every year to reach 681,000 tons in 2019, and China’s apparent demand for spandex grew to 782,900 tons in 2020, up by 14.97% year-on-year. In addition spandex exports also affected the domestic supply of spandex, according to statistics, in 2019 China’s spandex exports amounted to 74,000 tons, up by 28.2% year-on-year; in 2020 China’s spandex exports amounted to 78,500 tons, up by 6.08% year-on-year, an increase of 2.59% on the supply side, compared to 14.97% on the demand side and 6.08% on the export side. The “demand exceeds supply” situation is emerging, and production and sales are naturally pushing companies to expand production.

Since this year, Huafon Chemical has accelerated the pace of capacity development. On May 14, Huafon Chemical released a plan for a non-public offering of A shares in 2021, stating that the company intends to issue not more than 1.390 billion shares ( no more than 30% of the company’s total share capital before this issue) to not more than 35 selected investors, raising total capital of not more than 5 billion yuan, which will be used to invest in the construction of an annual output of 300,000 tons of differentiated Spandex extension project (RMB 2.8 billion) and 1.15 million tons/year adipic acid extension project (Phase VI) (RMB 2.2 billion).
Although many leading enterprises are already in the construction of production capacity, but the most recent production will have to wait until the end of November this year, spandex is currently facing a tight supply, which is still inevitable. In particular, the peak season in the second half of the year will inevitably see spandex prices rise and fabrics rise as well. In addition, the global pandemic is still ongoing, prevention of epidemic supplies such as: masks, protective clothing, medical bandages and other demand for spandex in the future also have a certain growth. Even if new production capacity is put into operation at the end of the year, it may be difficult to meet the additional demand.
“The current industry supply and demand remains very tight, with industry inventories continuing to remain at a minimum level of 12~14 days.” Guosen Securities analysts believe that spandex industry expansion in the future is mainly concentrated in the industry’s leading manufacturers, and new production capacity is mainly put in the second half of the year. The spandex industry in the second half of this year will still maintain a high industry boom. Product prices in the third quarter may still be a record high again.

“As of now, the effective domestic production capacity is about 870,000 tonnes. Although there are more new plans of adding capacity, they are mainly concentrated at the end of the year or next year, and the spandex boom is expected to continue in the short term.” Gong Yuqian said that if the new capacity is implemented as planned, it is expected to reach 1 million tonnes by the end of 2021, with a growth rate of nearly 15%, which will then effectively ease the tight spandex capacity.

As consumers begin to seek a new level of comfort, the core items for Spring/Summer 2022 will reflect the changes from the post-pandemic era. With the rise of multi-sport activities and the popularity of at-home fitness, consumers are expecting styles to suit their rather mobile lifestyle.
The lifespan of products is increasing and consumers are looking for products with durable and unique fabrics. Health remains a priority, with natural fibers and technology receiving attention.

The new trend of fitness tribe sees an increase of exercises in sports, such as yoga, running and cycling, exploring their origins with a theme of nature and slowing down and being mindful of lifestyles, to embrace the new trend of fitness.

Wanlihong Textile has something to say:
We are not only the carriers of fashion, but a fashion guide the future.
The next stop is to take you into the new fashion of sport!

Healing

This almost invisible flat knit is like another layer of your skin, will be the lightest fabric of this summer, durable yet light to the touch. Moisture-wicking and anti-abrasion. The knitted construction will make the silhouette more attractive, adding stretch and adaptability while avoiding bulkiness.
The hoodie brings a relaxed aesthetic to layered sportswear and is versatile enough to be worn for sports, leisure and casual wear. The sheer fabric provides a draping style and is very inclusive.

This season’s fabric collection takes its idea and creates a structural heterotopia in which the garments are shaped, deconstructed and reorganized in different materials and details to present a different look in each state of time and space. Variable structures, flowing drapes and fluid fabric features allow the same garment to take on different shapes, both dynamic and static.

Yellowing may cause complaints and conflicts between fabric producers and customers. Moreover, it will cost much money and time to avoid or eliminate this problem.

So there is no reason to ignore this problem.

In general, textile producers must deal with the yellowing caused by temperature and storage. However, yellowing of elastic fabrics is a more complex phenomenon that should be avoided. To a certain extent, yellowing may be caused by heat setting, shaping, storage.

The yellowing tendency of elastic fabrics varies depending on the material and the fiber additives used.

On the contrary, the diversity of customers and high demand are:

High white color and high brightness

Low yellowing when finishing (color matches original sample)

Phenolic yellow evaluation mark 4 is the lowest standard, as storage yellow bottom line

The finished product has a final pH of 4-7

Prevent exposure to Nox

▲The reasons of elastic fabrics become yellowish

Heat yellowing

Firstly, the greige fabric is heat-set on a gas tenter, which will cause severe yellow due to touch heat-finishing (forming) and bonding, especially sensitive for elastic fabrics made of polyamides and polyesters. These problems will be worse when microfiber products exhibit the extremely large surface area.

There are more and more problems caused by cotton / spandex blended fabrics. Easily yellowing when heat-setting to eliminate curling to obtain sufficiently stable dimensions. The fabric will usually turn brown after finishing the process. Therefore, it must pass the time-consuming and costly scouring and bleaching process to achieve the desired whiteness.

In order to prevent the heat yellowing, special auxiliaries have been designed to prevent or minimize yellowing.

Yellowing caused by Nitrogen Oxides.

Exposed to the nitroxide gas, the yellowing of polyester or polyamide fabrics depends on the spandex content- more or less shows a slightly yellow to reddish color change.

The deposition of fiber lubricants and the fabric additives have an additional effect on fabric Nitrogen Oxides yellowing.

In practice, we always come across high Nitrogen Oxides concentrations, such as those generated during heat setting (e.g. gas stenters), warehouses (e.g. truck exhausts), and some atmospheric contaminants (e.g. smoke).

The effects of exposure to nitrogen oxides depend on the extent of damage. Constantly the damage is discovered in some weeks.

Common antioxidants normally used to prevent heat yellowing and phenolic yellowing are not enough to resist the effects of nitrogen oxides yellowing.
