What Elements Guide Innovation?

"Fiber innovation is the focus of textile innovation."

Just a few years ago, it might be controversial whether the sentence was established. The role played by fiber over the past few years is only an indispensable raw material for the textile industry.

Now, whether it is terminal brand or downstream fabric enterprises, they have gradually recognized this view in practice.

Thus,

Trying to get rid of resource constraints.

A gratifying phenomenon is that people in the industry can talk about and popularize bamboo fiber, and finally add the "glue".

With the continuous development of the economy, resource constraints have become increasingly evident in all walks of life.

In the view of journalists, breaking the constraints of long-term resources and seeking sustainable sources of raw materials are not only the important reasons for the innovation of fiber varieties, but also the source of developing new varieties.

In the raw material structure of the textile industry, cotton used to occupy an absolute advantage, but after all, it did not match the rapid development of chemical fiber, and formed a pattern of its own.

Affected by various factors, cotton production has continued to decline. This year, prices have been increasing. The use of viscose staple fiber, polyester staple fiber and other alternative chemical fibers has increased, making the chemical fiber in the textile raw material pattern wins another.

However, whether it comes from such resources as polyester, nylon, spandex, acrylic fiber or viscose fiber made from cotton lint and wood pulp, it is also facing the resource crisis.

It is from this point of view that the trend of developing new fibers with renewable resources in domestic fiber industry is becoming more and more intense. Viscose fibers are undoubtedly the most suitable chemical fiber varieties to be innovated through raw material changes.

In the first two days, reporters saw in some large supermarkets that in the underwear and stockings area, the proportion of bamboo fiber products was very large, and consumers also liked bamboo textiles very much.

It can be said that bamboo fiber is the most effective and popularized application of a variety of new fibers.

Ligusticum Jilin chemical fiber bamboo fiber and Tianzhu industry alliance, Tangshan three friends of Yuzhu fiber, Shanghai China textile products of cloud bamboo fiber, plus Yibin siliya, Xinxiang chemical fiber, and so on.

Regardless of which quality is good, which market share is high, almost as long as it is viscose enterprise, must be divided into a cup of soup, bamboo fiber heat can be seen.

A gratifying phenomenon is that at present, people in the industry talk about and promote bamboo fiber, and finally can naturally add the "glue".

Bamboo fibers can be divided into 3 types: bamboo fiber, bamboo pulp fiber and bamboo charcoal fiber.

Bamboo fiber is limited by production difficulty and spinnability. The yield of bamboo charcoal fiber is still to be solved due to some technical difficulties.

At present, bamboo fiber is the main market, and viscose technology is adopted.

For a long time, in order to avoid the reputation of environmental and renewable bamboo fiber on "pollution", the viscose law is a taboo in many industry.

This phenomenon has finally been changed, not only due to the technological progress of viscose technology, but also the process of people's cognition gradually returning to reason.

In addition, protein fiber, pearl fiber, and so on, mostly viscose fiber as a carrier, the functional material attached to it, so as to have some special effects.

For the polyester polyester industry, which is the main raw material from petroleum, the innovative way of resources is to use biochemical raw materials partially.

The Sorona polymer application biotechnology in the US DuPont Co uses corn as raw material, which reduces energy consumption by 30% compared to petroleum based polymers, and reduces CO2 emissions by 63%.

The domestic production and Research Institute represented by Changchun Dacheng Group has replaced the bio based diols of renewable resources such as corn as the main raw material of polyester, and is also developing the technology of preparing biologically based diols from corn stalks to solve the concerns of "competing with people for food".

These new types of polyester are feasible paths for the innovation of polyester fabrics.

In addition, the use of waste plastic bottles and other production lines to regenerate chemical fibers, from low end to high-end, the new consumption mode of waste, renewable resources and consumer goods has been gradually recognized by consumers.

Minimize environmental constraints

The overall idea of eliminating the dyeing and printing process and advancing the dyeing process ahead is an improvement. It will be implemented by more enterprises in 12th Five-Year.

Of course, the resource constraint is only one aspect, with limited energy and strict environmental protection measures. These factors make the fiber variety innovation a breakthrough in another direction, technological innovation.

When a large number of enterprises strive to carry out energy saving and environmental protection reform on the traditional viscose method, other enterprises begin to march to the new technological route. The "Tencel" of Austria Lenzing Co, Lesel (Loycell) fiber, gives more inspiration to China.

Shanghai Textile Holdings (Group) has worked with Donghua University to develop and develop at least 1000 tons of annual production capacity. The Xinxiang egret has cooperated with China Textile Academy to develop a new solvent based cellulose fiber. The Fujian Hongyuan Group and the Chinese Academy of sciences have studied the solvent method of cellulosic bamboo fiber.

In fact, there are more than one thing in the field.

What is puzzling is that at present, there is no big progress in the field of domestic fiber in the country. Even Austria technology group, which is relatively mature in technology and has absolute voice, has not popularized "Tencel" as its fist product.

People in the industry have speculated that it is Lilin's strategic consideration that Tencel will be used as a reserve for "retaining programs" to find a more suitable opportunity to launch a heavy launch. Is Lesel still lacking in profit space for the complicated production process and high cost? Or, compared with the traditional viscose route and products, there are no special advantages for Lessle fiber, and it is hard to get market recognition. Reporters have learned that some domestic enterprises have begun to dig out the real reasons behind them, and take this as the basis for strategic planning.

The truth is expected to emerge.

In contrast, the promotion of coloring technology is much faster with the support of all parties.

Many enterprises admit that the development of raw liquor coloring products is largely inspired by the environmental protection of Jiangsu Xia Ke.

Xia Ke environmental protection uses raw liquor coloring technology to produce non dyed colored cotton, non dyed colored cotton and non dyed colored yarn, which eliminates the traditional dyeing and printing process, and is easy to dye, with bright color and high color fastness.

Now, this technology has been applied to many kinds of nylon, viscose fiber and so on.

Over the past two years, the exhibition of yarn dyed fabrics has promoted the introduction of coloring products.

For example, the colored red nylon dyed nylon, developed by the Zhejiang group, has been designated by many end customers. This year, the company plans to sell more than 1000 tons of colored yarn. The black viscose fiber of Tangshan Sanyou has been one of the main products of the company, and the future output is expected to continue to expand.

Although there are still some controversies about the "how to make the true coloring of the original solution" so far, the overall idea of eliminating the dyeing and printing process and advancing the dyeing process ahead of time is an improvement. It will be implemented by more enterprises in 12th Five-Year.

Fully meet functional requirements

Unfortunately, the more well-known terminal brands, the more inclined to use imported raw materials, although domestic fiber innovation, but it is difficult to be reassuring.

Besides the bioconversion of some raw materials, the innovation of polyester and other petroleum derivatives is mainly reflected in functional and differential aspects.

Under different historical conditions, chemical fiber has gone through the stage of simulation and high simulation, and has gradually moved to the super simulation stage.

Polyester imitation silk makes chiffon fabric a popular fashion in summer. Polyester and acrylic fibers imitate fur, so noble is no longer the patent of the rich; polyester Imitation cotton makes moisture absorption and air permeability no longer insulated with chemical fiber.

Because the chemical fiber is more operable than the natural fiber production process, some functional products such as thermal fiber, constant temperature fiber and far-infrared fiber have been born to meet the requirements of different occasions, seasons and individuals.

Hygroscopic and perspiration fiber Coolmax, hollow thermal insulation fiber Sunlite, air conditioning fiber Outlast, etc., are used by the terminal brand in sportswear and underwear, which fully reflects the functional properties of fiber materials.

Unfortunately, the more well-known terminal brands, the more inclined to use imported fibers and fabrics, although domestic fiber innovation, but it is difficult to be reassuring.

PTT fiber has the characteristics of polyester and nylon. It has been popular in foreign countries.

Later, due to the limitation of application scope and the impact of the financial crisis, some enterprises, mainly Shell, stopped production or reduced the scale of PTT fiber production.

Jiangsu Sheng Hong group innovates the development of memory fabrics with PTT filament, and innovates the idea of producing multi foreign PTT short fibers for carpets, leading the market trend.

On the basis of opening up the PTT fiber industry chain and solving the constraints of raw materials 1 and 3- propylene glycol, Sheng Hong will vigorously promote PTT products in the future.

At present, more and more fields are in urgent need of high technology and high performance materials, so that the industry has developed a new type of special fiber with Chinese characteristics, such as polysulfonamide and so on.

Broaden the scope of application and make fiber innovation more flexible.
