Analysis Of Development Direction Of Industrial Fiber Starts From Downstream Demand.

From the latest operational data, we can see that our country

The overall operation trend is not good, the overall performance of the industry is relatively low, and profits are greatly reduced. As one of the downstream industries, the industry textile industry is outstanding.

Statistics show that in the 1~4 months of this year, the gross domestic product output of the industrial textiles industry has increased by 19.44%, far higher than the industry average.

Experts predict that the overall quality of the overall operation of the industry will decline, the two digit growth of the industrial textiles industry will be more secure this year.

As the upstream industry, it is very important to fully understand the current situation, problems and needs of the industry in terms of fiber utilization.

Fiber for filtration and separation: should follow the trend of the trend.

Wang Hua, director of the hi tech fiber Research Institute of Sichuan Textile Science Research Institute, told reporters that the increasing variety of filter materials is an indisputable fact. Natural materials, such as natural fiber, synthetic fiber, inorganic fiber and metal fiber, are developed in recent years. In recent years, China has also developed high temperature resistant filter materials including aromatic polyamide, polyimide and polytetrafluoroethylene.

For example, polytetrafluoroethylene, its maximum use temperature can reach 260 degrees Celsius.

"But in my opinion, technology is not the most worrying problem. It is more noteworthy than technology. I think there are two more points."

Wang Hua said that most of the fiber producers in China do not understand the latest trend and development level of foreign fiber production, including the fiber production enterprises specialized in producing filtration and separation textiles. Therefore, news blocking has become one of the stumbling blocks for many enterprises to develop poorly and can only be used as low-end products. "There are still some companies who like to stick to the rule of law and are accustomed to producing with one kind of material and give up better choices, which is also very unfavorable for the development of enterprises."

In addition to dust filtration, liquid filtration is also the main area of application of textiles for filtration and separation.

According to Zhang Hongwei, Secretary of the Party committee of Tianjin University of Technology, "at present, the fiber needed for domestic water treatment components must have a strong anti pollution capability, but at present, most domestic fiber production enterprises can not meet the above requirements, and generally rely on imports."

In recent years, Tianjin University of Technology has made some progress in this respect.

It is understood that at present, Tianjin Industrial University has adopted the radiation grafting technology to prepare a high flux and high pollution resistance polyvinylidene fluoride PVDF hollow fiber membrane, which is more than 50% higher than that of traditional technology. In addition, the energy consumption level of the polyvinylidene fluoride hollow fiber membrane has been reduced by more than 15% because of the low pressure technology.

Geotextile and building fibers: market need to be subdivided

For geotextile and construction textiles, due to its special filtration, drainage, isolation, reinforcement, seepage prevention and protection, it also puts forward high strength, constant elongation, super abrasion resistance, acid and alkali resistant fibers, degradability, aging resistance, sound insulation and flame retardancy.

To speed up the development and application of functional woven or warp knitted geotextiles and geomembrane (grille), pay attention to the ecological development of new geotechnical textiles, break through the industrialization technology of permanent membrane structure materials for light buildings, and develop new high technology geosynthetics processing technology.

Cui Zhanming, chairman of Shandong Hongxiang Chemical Fiber Group Co., Ltd., told reporters that the fibers used in geosynthetics are mainly polypropylene staple fiber, polyester staple fiber, polyester filament, glass fiber, split film wire, carbon fiber and so on.

"But at present, there is no market segmentation for geosynthetics fibers, and there is a lot of difference between them. The development of high performance fibers needs to be improved in this field.

Cui Zhanming said.

Medical and health fiber: industry development needs industry attention

At present, the development direction of medical and health textiles is to research and develop medical tissue and organ materials, develop high-end medical protective products, and promote new hygienic products.

The related specialized fibers are biomedical fibers, medical or hygienic grade PPT spunbonded special slicing and short fibers, biodegradable, antibacterial, super absorbent and other functional fibers and differential fibers.

The fiber produced by Shandong Huaxing Textile Group Co., Ltd. is the representative of medical and hygienic textile fibers.

Although the raw materials of chitosan fiber can be recycled, the raw materials that have practical application value are very limited each year.

However, because chitosan is a small industry, it can not attract the attention of the industry, lack of planning management, lack of professional research and technical personnel, seriously affects the in-depth research and development of chitosan technology, and the engineering and industrialization progress of the industry.

Facing the new development requirements in the new era, the research and development of medical tissue and organ materials, the development of high-end medical protective products and the promotion of new sanitary products are the future development directions. Therefore, more functional and differentiated specialized fibers can be produced in order to protect life and health.

Fiber for pport: part of the function is still lacking.

In recent years, with the improvement of people's living standard and the increase of consumption demand, the automobile industry has been developing vigorously.

The following are the hot and high-profile textiles used for pport, the special filament of air bag, strong adsorption, anti odor, antibacterial, flame retardant, mildew proof, moth proof, self cleaning and other differential fibers. The high-strength fine denier glass fiber and functional microfiber gradually begin to enter the market stage.

Zhejiang Hai Lide new material Limited by Share Ltd, as the raw material supplier of Volkswagen, Audi and other auto brands, has experienced the whole process of the development and application of the special air bag filament.

Ge Jun min, director of the company, told reporters that the processing of automotive airbag fine denier polyester high strength (low shrinkage) industrial filament is very difficult and highly technical.

"It has good physical and mechanical properties, high strength, light weight, good friction performance and good elasticity. In addition, it has high chemical stability and anti-aging properties. Under the folded volume, the products that are soft in fabric and are not easily rubbed on the face and skin of the airbags when they are inflated quickly are recognized by automobile manufacturers and consumers."

Future high-performance automotive interior trim

The multifunctional cover material and ecotype superfine fiber imitation leather fabric are the key points for the development of pport textiles.

For automotive interior fabrics, pportation tools, textiles and composite materials industry technology innovation strategic alliance, Gao Gong, Fan Qin said that the interior fabric fading light, affecting the appearance and life; flame retardant, sound insulation, poor resistance to glue; interior fabric lack of composite functionality; VOC seriously exceeded the standard; fog degree exceeded the standard, pparency reduced, affecting the poor comfort of sight; compound sponge non recyclable and other problems are real.

"We will work hard to solve these problems in the following aspects: pure polyester flexible composites, hemp polyester blended flexible composite materials, new automotive door panel cushion materials, and natural fiber composite materials."

Yu Fanqin said.

Fiber for safety and protection: multiple functions need concurrently

Textile for safety and protection is a special kind.

Type, fiber also put forward specific requirements.

Dr. Hao Xinmin, General Logistics Department's Quartermaster Equipment Research Institute, introduces that carbon fiber and PTFE fiber are more representative in high temperature resistant and flame retardant fiber materials. Among them, PTFE is one of the earliest varieties developed in high temperature resistant and flame retardant fiber materials. Its chemical stability is excellent, fiber surface has wax feeling, friction coefficient is small, and it is difficult to burn in high oxygen environment.

Flame retardant textiles can be widely used in public areas such as schools, hospitals, hotels, etc., and can also be used as working clothes for fire fighting, military operations and nuclear power.

High strength and high modulus fibers are now used in bulletproof clothing and bulletproof helmets, with high ballistic performance and large protective area. However, the strength and modulus of fibers are not high enough, the price is high, some of them are poor in temperature resistance and cohesiveness, and the resin system needs further optimization.

For conductive fiber, its application makes textile antistatic effect remarkable, durable and free from environmental humidity, and can be applied to special functional textiles such as electrostatic clothing.

Cold and warm fiber materials include hollow fibers, ultrafine fibers and far-infrared fibers. In the future, it will develop towards a multi-functional composite mode.

Fiber for structural reinforcement: active attack is the best policy.

China's earliest projects involving structural reinforcement materials are software materials, such as the 80000 people's Gymnasium in Shanghai, including the Expo Axis and the water cube. In this field, many of our fibers are polyester, polyolefin (PO), polyvinylpyrrolidone (PVP), and glass fiber and polytetrafluoroethylene.

"At present, fiber reinforced structural materials represent the highest level in the textile industry."

Li Lingshen, President of China Industrial Textile Industry Association, said, "the most important problem is that domestic carbon fiber production enterprises, including fiberglass production enterprises, do not know who to sell to after the production is finished. Bicycle factories can not think of buying carbon fiber for bicycles, but a lot of carbon fiber production enterprises are making bicycles themselves."

According to the introduction, carbon fiber is mainly used for sports and leisure products in China, and it is relatively less used for high technology. So the future development of carbon fiber will be very broad.
