After Ten Years Of Grinding A Sword, Two Years Later, How Much Do You Know About The Market "Meat And Potatoes" Fiber?

Super Imitation cotton fiber has become the best seller in the market.

In recent interviews with several polyester fiber manufacturers, reporters learned that since the beginning of this year, with the popularity of Nike, Adidas, Anta and other famous sports brands for the purchase of super Imitation cotton fabrics, the demand has been pmitted upstream. The number of super Imitation cotton fibers produced by fabric weaving customers has continued to increase.

The responsible person was even pleased to say to reporters: "the company's super Imitation cotton fabric has been discharged for two years."

This phenomenon has attracted special attention from reporters about the category of "super Imitation cotton".

"It looks like cotton, feels like cotton and looks like cotton", which is a remarkable feature of super Imitation cotton fabric and finished products.

But many people may not know that this kind of fiber that has finally become "meat and potatoes" has gone through a long period of nearly 10 years from project establishment, technical research to technological pformation, industrialization and product sales.

Fortunately,

The project itself has experienced bit by bit, also for the textile industry in China for new fiber varieties R & D, industrialization and market promotion, explore the "integration of industry, University, research and development" and "whole industry chain development" to do the birth of footnote.

The 12th Five-Year project "No. 1" is of great significance.

Although our consumers have a natural affection for cotton fibers, the reality is that as a global population, China must stick to the 1 billion 800 million mu "red line of cultivated land".

In order to effectively solve the contradiction between "grain and cotton competition", and to make the fiber have excellent performance as far as possible, how to develop an alternative fiber like cotton fiber has become an important topic before China's textile industry.

At the same time, China's "12th Five-Year plan" of textile industry and the outline of building a textile power (2010~2020) put forward that the development of new textile materials, especially the development of super simulation technology and differential and functional fibers, should be the primary task.

Under these background, in 2010, the chemical fiber industry technical innovation strategic alliance (hereinafter referred to as "alliance"), which was set up by China Chemical Fiber Industry Association and China Textile Science Research Institute Co., Ltd., was founded by more than 20 units such as Donghua University and Yizheng chemical fiber. It shared the national "12th Five-Year" science and technology support program of "super Imitation cotton synthetic fiber and textile industrialization technology development", and promoted the industrialization of scientific and technological achievements.

The total investment of the project was 330 million yuan, of which 84 million 410 thousand yuan was allocated by the state, which was then referred to as the "12th Five-Year" and "1 project" of China's textile industry.

In the process of tackling key problems and promoting industrialization in the super cotton imitation project, the synergy of "integration of production, teaching, research and application" and "upstream and downstream integration" has been maximally developed, and the "whole industry chain development mode" has been gradually formed.

The technical tackling of the project is undertaken by the China Textile Science Research Institute Limited and the University of East University. The industrial chain enterprises use technological research and development achievements to carry out industrial production, marketing and sales.

The industrialization of project technical achievements involves many fields such as chemical fiber production, spinning, weaving, printing and dyeing.

The whole project is completed, involving dozens of enterprises.

In terms of spinning, according to incomplete statistics, the annual capacity of China's super Imitation cotton fiber is about million tons. The chemical fiber enterprises involved include Yizheng chemical fiber, Sheng Hong group, and sik.

"Polyester products have high cost performance and lower price than regenerated cellulose fibers, but some of them have better performance.

Therefore, we want to give full play to the comparative advantage of polyester, make super Imitation cotton fiber into a large category, make an important substitute for cotton fiber, instead of making it a private house project with only a few hundred thousand tons of output.

As a member of the superimitated cotton project, it is a member of the technical research team, said Wang Xueli, a professorship professor at the textile science and technology innovation center of Donghua University.

At the same time, the China Textile Institute also relies on the alliance to launch the "Yi mian" brand and vigorously carry out the marketing and promotion of super Imitation cotton products.

For example, in recent years, every year at the yarn exhibition site, the reporters can see the striking position of the exhibition hall of the China spinning center and display the brand of "yam" and show underwear, T-Shirts, casual wear and other "yam" products.

During the "12th Five-Year" period, the super cotton imitation project carried out the comprehensive development of the product, and the promotion of the product also lasted until now.

After years of efforts, the scale of the production of super Imitation cotton has been expanding, and the application area has been expanding.

Say.

Fiber research and development process has gone through hardships.

Today, the market has become a "super pastry" super cotton fiber. It has gone through many hardships along the way.

The reasons are manifold.

First of all, the research and development of Imitation cotton fiber itself is very difficult.

Wang Xue Li

Then, how to understand the "super" in super cotton imitation?

Wang Xueli said that super means that it should first ensure the advantages of polyester, such as good mechanical properties, good drapability and quick drying effect.

Secondly, it has better performance than ordinary polyester. For example, it can be suitable for sports and fast drying, which will be more popular with sports brand.

Secondly, according to the law of global new materials research and development, a new material starts from R & D to large-scale production and application, and generally takes 10 years ~20 years.

Wang Xueli recalled: "although the super cotton imitation project was established in 2010, we have studied it for some time before.

Generally speaking, the super Imitation cotton has been developing from the beginning to large-scale production and application for about 10 years. "

"The process of developing a new fiber from development to success is really long. We have deep feelings about this.

Moreover, we will encounter various difficulties in the process of promotion, and we will invest heavily in all aspects.

As far as Donghua University is concerned, the school has set up dozens of R & D teams for this project to carry out technical tackling of the whole industry chain such as spinning, weaving, dyeing and finishing.

Wang Xueli sighed.

In the research and development of the project, the China Textile Institute has undertaken the whole process of equipment research and development, improvement, small test, pilot test, spinning process package development and so on, and has overcome all aspects of the problem.

It is worth mentioning that,

As we all know, in the field of polyester production, the mainstream spinning technology is melt direct spinning, but the super Imitation cotton fiber has developed a lot of efforts from the beginning to the direct melt spinning production.

Under the joint efforts of many parties, problems have been overcome.

On the whole, the super Imitation cotton project aims at the common defects of polyester fiber, such as poor hydrophilicity, short fiber easy pilling, low dyeing rate at atmospheric pressure, two steps dyeing of blended fabric, large rigidity and poor hygroscopicity of polyester fabric. With polyester molecular modification as the core, it breaks through the continuous polymerization technology of high capacity, multi component modified copolyester, fine fiber cross-section precise control technology, new textile and its pure spinning and blended fabric dyeing and finishing technology, and develops 3 kinds of new molecular structure super Imitation cotton polyester fibers and their series products.

As the sole representative of the textile industry, the project was selected as the national "12th Five-Year" scientific and Technological Innovation Exhibition in 2016.

The project has gained good economic benefits.

"We have done this for a long time, doing it, summarizing and perfecting it, and finally making super Imitation cotton products" look like cotton, feel like cotton, wear like cotton ".

That is to say, from the perspective of gloss, touch feeling, moisture regain and hygroscopicity, the super cotton imitation project has achieved the desired effect.

Wang Xueli sighed.

It is reported that the super Imitation cotton project has now formed 3 series of fiber products, which are easy to dye, high moisture regain and hydrophilic fine denier, which can effectively meet the needs of different markets.

Their hydrophilicity is better than that of conventional polyester fibers, and their moisture regain is different.

Among them, the moisture regain of high moisture regain product is 2 times higher than that of ordinary polyester fiber, and its quick drying property is much better than cotton fiber, and its skin affinity is close to cotton fiber.

Their low modulus, soft touch, finished products can be worn closely, color fastness is generally higher than cotton fiber, dry rubbing fastness is above 4, wet rubbing fastness is above 3-4 grade, and dyeing temperature is twenty or thirty degrees lower than that of conventional polyester fiber, which can be dyed at atmospheric pressure. The blended fabric "one bath one step" dyeing effect is good, and has good energy saving and emission reduction.

It is particularly noteworthy that the series is easy to dye, which has developed a polyamide ester super Imitation cotton fiber.

It is a kind of fiber that is copolymerized by binary acid, diol and amide group. It belongs to a brand new substance in chemical composition. It has applied for new material number (CAS:25610-75-7).

Polyamide ester super Imitation cotton fiber has many outstanding characteristics: first, it feels like cotton.

If the blind is tested, the handle is basically the same as that of cotton fiber products.

Two, in the aspect of dyeing property, the series can be dyed under atmospheric pressure, while ordinary polyester fibers are mainly dyed at high temperature and high pressure.

Three, its fiber strength is designed according to the strength of cotton fiber. It is only a little higher than cotton fiber, and its pilling resistance is better than that of ordinary polyester.

Four, its moisture regain is about 2 times that of ordinary polyester, and has better moisture absorption and quick drying performance.

At present, this series of fibers has been widely used in sportswear, casual wear, tooling and other fields.

The industrialization of polyamide ester super Imitation cotton fiber industrial enterprises choose Yizheng chemical fiber.

Yizheng chemical fiber gave it a popular name - "Yi Lun".

According to Yizheng chemical fiber related responsible person, "Yi Lun" products in recent years, the market demand grew very fast.

Reporters also learned that the polyamide ester super Imitation cotton fabric has been produced in Ru Tai shirt fabric, copper cattle home products, and

The products are applied.

The demand for downstream growth has stimulated the production of fiber enterprises, so that they have gained good economic benefits.

According to Lian Zhijun,

As for the economic benefits of super Imitation cotton fiber, Sheng Hong group is one of the enterprises that have the right to speak.

As the world's leading differentiated fiber manufacturer, Sheng Hong group is a fiber supplier of several internationally renowned sports retail brands.

The group's marketing department responsible for brand operation told reporters that lifestyle changes made consumers demand for functional fabrics and comfortability of sports fabrics more and more.

Compared with the general polyester fabric, the sportswear fabrics made of super cotton imitation fiber have better moisture absorption, sweat perspiration, better skin affinity and stronger functionality. Therefore, the super cotton imitation products produced by the company have been booming in recent two years, and sales have increased rapidly.

In fact, like Sheng Hong group, there are still a large number of enterprises that have achieved good economic benefits from the sale of super Imitation cotton products.

According to incomplete statistics,

This also means that the super Imitation cotton project has stepped out of the laboratory step by step. Now the product has been widely promoted and applied, and has yielded fruitful fruits.
