New Mainstream Of The Textile Materials Market: Heterogeneous Shrinkage Polyester Fiber

Sun Derong told reporters that he also added 4 new differences this year.

Production line, the annual production capacity of composite wire 40 thousand tons, sales revenue will reach 600 million yuan, profits and taxes of nearly 100 million yuan, more than 300 new jobs.

As a kind of fiber produced by spinning, stretching, twisting and other similar or non similar fibers, the development of the shrinkage shrinkage composite polyester fiber has greatly improved the simulation level of our fibers. The series products are evenly distributed and fixed length, so as to ensure the flatness and shrinkage of the fabrics produced by the downstream enterprises, and the semi-finished products of all the processes can be processed at the same time, so as to improve the efficiency, reduce energy consumption and save costs.

One step or two step method

At present, different shrinkage composite polyester fiber mainly adopts one-step FDY/POY differential shrinkage composite spinning technology. The technology has the characteristics of less investment in equipment, short process flow, low production cost, high speed production, stable product quality, arbitrary composition of components and properties.

Such an advanced technology, its industrialization development is not an easy task.

Jiangsu Si Ke difference Fiber Technology Co., Ltd. is a solution to solve the problem of industrialization of heterogeneous shrinkage fiber.

Sun Derong, chairman of the company, told reporters that theoretical calculation is no problem, but the actual process, operator skill level, equipment accuracy, temperature change and other factors all affect the development of research and development.

After more than two years of hard exploration, the unimaginable product finally came out.

"We have designed a one-step process for POY+FDY parallel spinning and high-speed compound network with multiple machines in one step, breaking through the key technologies such as complex point tension matching, accurate control of different shrinkage and high-speed multiple networks, and developed special synchronous equipment for spinning, synchronous winding, double air chamber, double air channel side blowing system, multi head precision high-speed winding head and other key equipment.

On this basis, the test and evaluation method of the differential shrinkage performance of the product was established for the first time, and the technical conditions of the optimal spinning, dyeing and finishing process of the one-step method were studied.

It reduces manpower, site and electricity consumption and water consumption, complies with the development trend of low carbon economy, and is consistent with the national industrial policy.

Sun Derong said.

Although one-step production

It is the mainstream in the market now, but the products produced by the two step method have their own characteristics and advantages.

Cui Li, director of new product development at Limited by Share Ltd, new Feng Ming group, told reporters that the speed of the new Feng Ming flat is generally 700 to 900m/min. The network pressure of different shrinkage composite wires can be adjusted according to the requirements of customers to meet the weaving requirements of different fabrics. The drafting multiple and the qualitative temperature can also be adjusted to meet the requirements of different customers for boiling water shrinkage.

Whether it is one-step or two step production, the different shrinkage composite polyester fiber has excellent light shielding properties, excellent dyeing properties, high porosity and soft handle. At the same time, because of many silk rings on the surface of the fiber, it also eliminates the extreme light defects of chemical fiber fabrics.

After processing, you can make high-grade woolen fabric, spandex sweat cloth, high grade peach skin, jute linen, crystal linen, chiffon, water washed velvet, straight Gong, Prince Edward, etc., which is the ideal material for T-shirt and thermal underwear.

Clear pattern and broad prospects

As a new type of differential fiber, the development of the market has a good prospect. At present, some well-known large-scale chemical fiber enterprises in China are involved in this field, such as Zhejiang Tong Kun group and Jiangsu Hengli Group.

On the one hand, enterprises can pform the existing new equipment to produce new shrinkage shrinkable composite fibers. On the other hand, they can cooperate with the domestic textile machinery manufacturers to develop special equipment for shrinkage shrinkable composite fibers to develop new shrinkage shrinkable composite fibers, and gradually form the industrial pattern of different shrinkage fibers, and be applied to more and more chemical fiber market, and gradually accepted by the market.

The first breakthrough of the application and development of the new type of shrinkage fiber is the application and development of the ordinary chemical fiber in the field of fiber materials, that is, the improvement and improvement of the ordinary chemical fiber, making it closer to natural fibers and more convenient for production and processing.

It is expected that the chemical fiber can maintain its high strength and uniform characteristics and possess excellent properties of natural fibers.

Therefore, high elasticity, easy dyeing, hygroscopic, bulging, gloss improvement and so on become the goal of ordinary chemical fiber deformation and modification. Its future development and pattern are as follows: using high elastic shrinkage technology to manufacture high shrinkage yarn, making low shrinkage silk with stereotyped elongation technology, and making two super shrink shrinkable composite wires, mostly used for thin pile up and new simulation silk fabrics.

Development of three polyester fibers and polyester fibers.

Three because of its different fiber size, heteromorphic cross section, double shrinkage and fine filament size, it has been a good material for imitation silk, peach skin, imitation deer skin and wool like fabric. Its texture is soft, delicate, full and comfortable. It is the focus and direction of differential fiber development in mainland China.

Functionalization of double shrinkage heterogeneous composite wire.

As a low shrinkage component, boiling water treatment appears on the surface of the fabric, preventing ultraviolet, flame retardant, antibacterial and so on.

Crimp of low shrinkage component filament.

Although there are a lot of coils after the boiling water treatment of double shrinkage and different composite wires, the shape of coils can only be bent in the form of contraction and extrusion at both ends. The bending part is not curled. For example, PET/PTT composite wire, a crimp like fiber, can be used as a low shrinkage component to compounded the high shrinkage polyester filament blended into two threads, and the handle will be softer.

Double shrinkage and multi composite filament yarn. It is mostly used for imitation hemp and wool like.

Research and development of high double shrinkage composite wire.

The shrinkage rate is increased by spinning different raw materials or modifying polyester raw materials.

Cui Li introduced: "at present, new Feng Ming has formed the capacity of 38 thousand tons of different shrinkage polyester polyester fiber. Next, we will pform the 2 melt direct spinning lines of the group's subsidiary company Zhongxin chemical fiber, specializing in the production of polyester fiber with different shrinkage. It is estimated that the capacity of our shrinking polyester composite fiber will reach 80 thousand tons per year in 2013."

Sun Derong told reporters that shulke will also add 4 differential hybrid fiber production lines this year. The annual production capacity of composite fiber is 40 thousand tons. The sales revenue will reach 600 million yuan, the profits and taxes will be nearly 100 million yuan, and more than 300 jobs will be added.

And Jiangsu Hengli Group responsible person told reporters that the one-step method of shrinking polyester composite fiber production capacity in the future there is room for expansion, and raised concerns: the shrinking of the composite polyester fiber in the early stage of the hot sales led to the trend of the country, easy to enter the vicious competition.

Tung Kun group responsible person said that the company's new contractile composite polyester fiber in the next 5 years will gradually expand the level of industrialization, it is estimated that output will reach 35000 tons / year by 2018.

For future development, experts in the industry say that in a certain period of time (within 5 years), the new product can not replace the traditional two step method of different shrinkage composite fibers. The traditional shrinkage fibers will also exist for a long time and dominate the market.

In the next 5~10 years, the technical bottlenecks of new products will gradually overcome, and the advantages will be brought into full play, and gradually occupy the market, and will be accepted by the market and customers, and gradually become the leading products of different shrinkage fibers. The traditional two step method of shrinking fibers will be gradually eliminated.
