The textile industry is facing the test of raw materials

At present, China has become the largest producer of many fiber varieties, and it is also the world’s largest textile fiber processing and application country. Many textile fiber raw materials, such as wood pulp for viscose fiber production and crab shell for chitin fiber production The petrochemical raw materials for the production of synthetic fibers are also heavily dependent on imports.

As the global population soars, in order to ensure the supply of food for the global population, China and other countries in the world have stepped up the control of arable land for food. Cotton, all kinds of hemp (ramie, flax, jute, ramie, etc.), sericulture of sericulture are restricted.

The depletion of oil and natural gas resources has sounded the alarm for the synthetic fiber industry. The United Nations issued a forecast in 2000 that global oil will be basically used up by 2070. On November 8, 2010, a scholar from the University of California at Davis announced that global oil and gas will be depleted by 2050. Not only does it have an impact on global energy demand, it also has a huge impact on synthetic fibers that use petrochemicals as raw materials.

The climate, environment, and material needs also have new impacts. Global natural disasters such as dry spells, floods, and flash floods have reduced the production of many biomass resources. For example, Australia’s drought for seven consecutive years has led to a sharp contraction of sheep and sheep, and the production of sheep wool (cleaning hair) has dropped by 30%. The global environment is deteriorating. In order to maintain the “green” and “low-carbon” concept of the environment, progressive and strict management regulations have been put forward for the discharge of sewage, sewage, and gas in production and processing, and the processing of textile raw materials (such as degumming, wool washing, etc.) And fiber processing (printing, dyeing, finishing, wastewater treatment) brings many constraints.

Under the current predicament, traditional textile raw materials must explore new ideas and roads to realize the dream of textile power.

Natural fibers must cultivate new varieties. Under the premise of improving fiber properties (especially to ensure the fineness and strength of fibers), they should not use “grain fields” or “cultivated land” as much as possible, and use saline-alkali land, floodplain land, and hillside land for planting. Ensure that the food supply under the population situation is drastically increased.

Chemical fibers must use new technologies to make the best use of “biomass resources that can be regenerated, degradable, recycled, and environmentally friendly”.

The recycling of waste textiles around the world has been gradually carried out. At present, there are more than 50 million tons of waste textiles in the world. These wastes are not only rarely used, but they also pollute the environment after they have been abandoned. The recycling of waste textiles has also started in China.

In order to adapt to the special requirements of industrial textiles and various special requirements of protective clothing, various new high-performance fibers, such as high temperature resistance, low temperature resistance, high strength, ultra high strength, high modulus, ultra high modulus, Low modulus, special optical properties, special electrical properties, and special magnetic properties Fibers also need to be researched and developed to meet the needs of the textile industry.

For the cotton textile industry, cotton textile companies should broaden their horizons, extend the industrial chain further, coordinate the development and processing of dyeing and finishing, apparel, household and industrial products, and market and service the final product, while extending forward to coordinate cotton. Breeding, planting, collecting and processing. At the same time, we must cooperate with the test to develop and use "new super imitation cotton" fibers.

Broadening the horizon is based on the needs of the high-performance and new functions of the final product, letting go of differentiated, high-performance, and new-functional fiber materials. Clothing and home textiles production should take into consideration new functions such as perspiration, moisture permeability, bacteriostasis, antibacterial, odor control, UV protection, anti-static, flame retardant, and anti-electromagnetic radiation. In the field of industrial textiles, high-performance fibers such as high-strength, high-modulus, low-modulus, high-temperature resistance, low-temperature resistance, insulation, electrical conductivity, magnetic conductivity, sound absorption, and shock absorption should be considered, and efforts can also be made in spinning technology. According to the development of new spinning technology (Siro spinning, sirofil spinning, parallel spinning, low torque spinning, embedded composite spinning, etc.), we can make full use of filaments while spinning short fibers. Fiber with spinning, blended, wrapped spinning and so on.

With the intensification of the shortage of traditional cotton textile raw materials, all kinds of natural fibers, ultra-imitation cotton fibers, differential fibers, new functional fibers, high-performance fibers, including silk, various chemical fiber filament and other textile raw materials will enter the cotton textile system. Products will be developed for high-end, top-end clothing textiles, home textiles and industrial textiles. Enterprises should change their thinking mode and get rid of the concept of traditional “pure spinning”. At the same time, the textile industry should broaden its horizons and extend its scope to the "first" and "tail", focusing on the design, production, marketing, and service of the final product, as well as on the breeding, production, and supply of raw materials. In the current critical period of transformation and upgrading, lay the foundation for the stable development of the textile industry, form a system, improve the organization, occupy space, and contribute to the smooth development of the textile industry.
