3. Great potential for development

At present, China's chemical fiber filament weaving industry is mainly concentrated in the coastal developed areas. Domestic cotton textile, knitting and other industries have begun to transfer from China's eastern region to the central and western regions and Southeast Asia during the eleventh Five-Year Plan period, and the chemical fiber filament weaving industry can digest the relatively high cost of production factors in developed coastal areas and always maintain healthy and rapid development, indicating that the market potential and competitive advantages of the industry still exist.

According to the United Nations forecast, the global textile fiber processing volume will reach 253 million tons in 2050, of which the average annual growth rate of chemical fiber filament fabrics is 3%, and the market potential of chemical fiber weaving industry is huge.

The development prospect of filament weaving industry

Since entering the 21st century, the chemical fiber filament weaving industry has played an increasingly important role in promoting the development of spinning technology, fiber simulation technology, weaving technology, chemical fiber printing and dyeing technology, and fabric finishing technology, and guiding the development of high-performance multi-functional textiles. It plays a key role in connecting the links from chemical fibers to clothing fabrics, home textiles and industrial textiles. As an industry with rapid development, rich in high-tech and rapidly expanding product application range, the chemical fiber filament weaving industry plays an important supporting role in promoting the textile industry to achieve the strategy of science and technology power and brand power, and in the textile industry to achieve environmentally friendly and sustainable development strategy.

With the development of artificial intelligence, electronics, medicine, architecture, aerospace and other technologies, new chemical fiber filament fabrics continue to emerge, the application is more and more broad, chemical fiber filament fabrics in smart wear, medical, agriculture, national defense, aerospace and automotive and other fields play an irreplaceable role.

Advantages and disadvantages of water jet loom

In the chemical fiber filament weaving process, the weaving equipment used is mainly water jet loom, air jet loom and rapier loom and other looms are supplemented, and the shuttleless rate of loom is 100%.

Water jet loom, which uses water as weft insertion medium, can effectively eliminate the influence of chemical fiber static electricity on weaving, and is the most suitable equipment for chemical fiber filament weaving, especially for hydrophobic filament weaving such as polyester. Compared with air jet, rapier and shuttle loom, water jet loom has the characteristics of less investment, less labor, high efficiency, energy saving, and the most suitable for the production of hydrophobic chemical fiber fabric. The disadvantage of the water-jet loom is that its weft insertion with water will produce a certain amount of production wastewater, which needs to be treated and reused, and it is not suitable to put the water-jet loom upstairs for production.

Water jet loom is the best model for producing chemical fiber filament fabric. With the growing market demand for chemical fiber filament fabrics, the chemical fiber filament weaving industry is booming and will continue to maintain stable and rapid growth, and the future demand and investment will also maintain a growth trend.

Treatment of water jet weaving wastewater

Recently, affected by environmental protection policies, key industrial clusters such as Xiuzhou District, Jiaxing City, Zhejiang Province, and Wujiang District, Suzhou City, Jiangsu Province, have increased the regulation of the industry's water jet loom, focusing on the "small, scattered and chaotic" situation of the cluster. Shut down "no license no license, no environmental assessment, no record, unauthorized new water loom" that is, "low small scattered" enterprises; Through standardization and upgrading, all large-scale enterprises will be concentrated in industrial parks, and 100% of sewage treatment and reclaimed water will be realized.

The main pollutants in water jet loom wastewater are oil and slurry. The pollutants are relatively simple and much easier to treat than printing and dyeing wastewater. The sewage can be reused after simple treatment such as air flotation, filtration and activated carbon sterilization. At present, many enterprises and parks have realized 100% treatment and 100% reuse of sprinkler wastewater. In other words, as long as the production water of the water jet loom is implemented, the water can be reused many times, and the discharge is completely zero.

At present, most enterprises adopt self-built water treatment system to realize the reuse of reclaimed water, in order to achieve the goal of saving water resources, reclaimed water and controlling sewage discharge. Local governments and competent departments are also very enthusiastic about the reuse of reclaimed water, and generally will centrally treat wastewater to ensure the effect of treatment and the comprehensive utilization of water resources, give full play to the regulatory role of the market, and enhance the sustainable development of the upstream and downstream through the transformation and upgrading of the industry, so as to achieve the environmentally friendly, green and harmonious development of the whole textile industry chain.
