The latest revision of the national development and Reform Commission: what will be restricted and eliminated in the textile printing and dyeing industry in the future?
Recently, the national development and Reform Commission and relevant departments revised the guidance catalogue for industrial structure adjustment (2011 version) (Revised), forming the relevant "draft for comments", and solicited 923 constructive opinions from relevant departments, local enterprises, industry associations, etc., which has positive reference significance for further improving the guidance catalogue for industrial structure adjustment (2019 version).
The guidance catalogue is divided into three categories: encouragement category, restriction category and elimination category. The number of categories of textile industry is as follows:
01 textile industry - encouraged
Continuous copolymerization modification of differential and functional polyester (PET) [cationic dyeable polyester (CDP, ECDP), alkali soluble polyester (COPET), high shrinkage polyester (hspet), flame retardant polyester, low melting point polyester, amorphous polyester, biodegradable polyester, polyester produced with green catalyst, etc.]. High efficient and flexible preparation technology of flame retardant, antistatic, UV resistant, antibacterial, phase change energy storage, photochromic, original solution coloring and functional chemical fiber.
2. Development, production and application of new polyester and fiber, such as PTT, pen, PBT, PBS, PCT, bio polyamide and bio furan ring

6. Set up the intelligent spinning factory, adopt the intelligent and continuous spinning complete set of equipment (short process advanced spinning equipment such as blowing carding unit, roving unit, fine winding unit and numerical control single machine, air-jet vortex spinning, high-speed rotor spinning, etc.) to produce high-quality yarn. High count, high density, jacquard and other high-grade woven and knitted textiles
7, the use of digital intelligent printing and dyeing technology and equipment, dyeing and finishing clean production technology [enzyme treatment, high efficiency short flow pretreatment, knitted fabric continuous pre-treatment, low temperature pretreatment and dyeing, low salt or salt free dyeing, low urea printing, small bath ratio air or gas liquid dyeing, digital inkjet printing, foam finishing, etc.), functional finishing technology, new dyeing processing technology, composite surface Material processing technology, production of high-grade textile fabrics. Development and application of intelligent package dyeing equipment

9. Development and manufacture of intelligent, high efficiency and low energy consumption textile machinery, key special basic parts, measuring and testing instruments and test equipment
10. Production of high grade carpet, spinning and embroidery products
11. Development and application of digital, networked and intelligent garment production technology and equipment
12. In textile industry, bio degumming, PVA free sizing, energy-saving printing and dyeing process with less water and water, high-efficiency treatment of "three wastes" and promotion and application of resource recovery and reuse technology
13. R & D and application of recycling technology and equipment for waste textiles, and production of high value-added products such as polyester industrial silk, differential and functional polyester filament and nonwovens with polyester recycling materials
