my country is a major country in textile fiber application and processing in the world
It is known that the depletion of natural gas and oil resources has sounded the alarm for the synthetic fiber industry. The United Nations announced in 2000 that the world’s oil would be basically exhausted by 2070. On November 8, 2010, scholars from the University of California, Davis, announced that the world’s oil and natural gas would be exhausted by 2050. It not only has an impact on global energy demand, but also has a huge impact on synthetic fibers based on petrochemicals as raw materials.
Today, our country has become a major producer of many fiber varieties, and is also a major country in the application and finishing of fabric fibers in the world. Many fabric fiber raw materials, such as crab shells for the production of chitin fiber, wood pulp for the production of viscose fiber, Petrochemical raw materials used in the production of synthetic fibers also rely heavily on imports.
As the global population surges, in order to ensure food supply for the global population, China and other countries around the world have tightened their control over the cultivated land used to grow food. The cultivation of cotton, various types of linen (flax, ramie, kenaf, jute, etc.), and mulberry trees for sericulture are all restricted.
The environment, climate, and material demands have also brought new impacts. Global floods, droughts, flash floods and other natural disasters have reduced the production of many biomass resources. For example, seven consecutive years of drought in Australia have significantly shrunk the sheep flock, and sheep wool (washed wool) production has dropped by 30%. The global environment is deteriorating. In order to maintain the “green” and “low-carbon” concepts of the environment, gradually stricter regulations have been put forward for the discharge of dirt, sewage, and pollutants during production and finishing, and for the finishing of fabric raw materials (linen degumming, wool washing, etc.) and fiber finishing (printing, dyeing, finishing, wastewater treatment), etc. bring many constraints.
Under the current predicament, traditional fabric raw materials must explore new ideas and paths to realize the dream of becoming a fabric powerhouse.
Chemical fibers must make use of new technologies and make full use of “biomass resources that can be regenerated, degraded, recycled, and environmentally friendly.”
New varieties of natural fiber must be cultivated. On the premise of improving fiber performance (it is very important to ensure the fineness and strength of the fiber), the full amount does not require “grain fields” or “arable land”, and uses saline-alkali land, wasteland, and hillside land. Waiting for planting to ensure food supply in the face of population explosion.
The recycling of waste fabrics around the world is gradually carried out. Currently, there are more than 50 million tons of discarded fabrics globally every year. These wastes are not only rarely used, but also pollute the environment after being discarded. The recycling of waste fabrics has also begun in China.
In order to meet the various extraordinary requirements of industrial fabrics and protective workwear, various new high-performance fibers,
For example, fibers with high temperature resistance, low temperature resistance, high strength, ultra-high strength, high modulus, ultra-high modulus, low modulus, very perfect mechanical properties, very electrical properties, and very magnetic properties still need to be developed in order to Meet the needs of the development of the fabric industry.
For the cotton textile and weaving industry, cotton textile and weaving enterprises must broaden their horizons, extend the industrial chain backward, and develop, organize and interoperate with dyeing and finishing, workwear, household and industrial products, as well as the final product market and servitization. Extend forward to coordinate cotton breeding, planting, harvesting, and finishing. At the same time, we must cooperate with experiments to develop and adopt “new super cotton-like” fibers.
Broadening our horizons means adopting differentiated, high-performance, and new functional fiber raw materials based on the high performance and new functional requirements of the final product. The production of work clothes and household fabrics should consider new functions such as sweat wicking, breathability, bacteriostasis, antibacterial, deodorant, covering, static elimination, fire protection, and electromagnetic radiation protection. In terms of industrial fabrics, we should consider high-performance fibers such as high strength, high modulus, low modulus, high temperature resistance, low temperature resistance, insulation, conductivity, magnetic conductivity, sound absorption, and shock absorption. We can also work on spinning technology. , according to the progress of new spinning technologies (siro spinning, sirofil spinning, parallel spinning, low torque spinning, embedded laminated spinning, etc.), full utilization of short fiber spinning can be achieved Filament fiber companion spinning, blended chemical fiber fabrics, wrapped spinning, etc.
As the shortage of traditional cotton textile raw materials intensifies, various natural fibers, super-imitation cotton fibers, differential chemical fibers, new functional fibers, high-performance fibers, including silk, various chemical fiber filaments and other fabrics All raw materials will enter the cotton textile weaving system. The products will be developed for high-end, high-end workwear fabrics, household fabrics and industrial fabrics. Enterprises should change their thinking mode and get rid of the traditional concept of “pure spinning” superiority. At the same time, the fabric industry should broaden its horizons and extend to the “head” and “tail”, focusing not only on the design, production, market and service of final products, but also on the breeding, production and supply of raw materials. In the current critical period of transformation and upgrading, we will lay the foundation for the stable progress of the fabric industry, form a system, improve the organization, occupy space, and contribute to the smooth progress of the fabric industry.
