Urban Minerals To Be Excavated: Recycled Fiber

< p > Sweden a href= "http://www.91se91.com/news/index_c.asp" > garment enterprise < /a > H&M recently announced that the company used the old clothes collected to produce a pair of jeans.

The recycled fiber content of the jeans is 20%, and the new concept of environmental protection is adopted in the design, which aims to reduce the harm to the environment.

< /p >

Last year, at the end of last year, Zhejiang beauty New Material Co., Ltd. provided chemical recycled fiber for the uniforms of CBA (Chinese Basketball Association) sponsored by Li Ning Co, and also received more and more recognition and attention for recycled fiber.

< /p >

< p > circular regeneration < a href= "http://www.91se91.com/news/index_c.asp" > fiber < /a > is an important treasure of "urban mineral resources" to be excavated.

If the industry is more mature, the cycle of garment production drives the cycle of individual consumption, and the cycle of consumption stimulates the production cycle. This will be a vivid portrayal of the circular economy.

< p > the State Council promulgated the "opinions on accelerating the development of energy saving and environmental protection industry" last year. The opinions clearly put forward the development goal of energy saving and environmental protection industry in the next three years: the annual output growth rate is above 15%, and the total output value reaches 4 trillion and 500 billion yuan by 2015.

The importance of national policies will help the energy saving and environmental protection industry to enter the fast lane of development.

The opinion points out that the energy conservation and environmental protection industry refers to the industry that provides material and technological support for saving energy resources, developing circular economy and protecting the ecological environment. As one of the 7 strategic emerging industries to accelerate the cultivation and development of the country, development is facing a rare historical opportunity.

< /p >

< p > recycled recycled fiber industry is also like this < a href= "http://www.91se91.com/news/index_c.asp" > environmental protection industry < /a >.

Last year, the national development and Reform Commission said at various meetings in the chemical fiber industry that the State supports the development of recycled fiber industry.

Last year, the China Chemical Fiber Industry Association organized the seminar on the access conditions of recycled chemical fiber industry. Wang Wei, deputy director of the Department of consumer goods industry of the Ministry of industry and information technology, took part in the discussion and listened directly to the opinions and suggestions of the enterprises on "access conditions".

Globally, the status of recycled fiber is also increasing. < p >

Recently, the global organic textile standard (GOTS) International Working Group promulgated the 4 edition of the qualified global standard for textiles processing and processing of organic natural fibres.

The new version has revised the standard of adding fiber materials, and the composition of regenerated synthetic fiber can reach 30%.

The new version of recycled fiber is defined as raw materials that must come from certified organic production, that is, continuously managed forests or certified recycled materials.

For synthetic fibers, raw materials must be recycled and certified according to recognized standards.

< /p >

Below P, the concept of recycling consumption is being guided by high-end brands.

Major international textile and garment enterprises are making efforts to recycle waste materials.

Wang Baoying, environmental safety manager of Nike sourcing services (Guangzhou) Co., Ltd., China, said Nike is driving sustainable production and supply chain by optimizing products and processes.

Nike set three levels of gold medal, silver medal and bronze medal for environmental design of products. The goal of environmental protection design of footwear products is to achieve the silver target in fiscal year 2015, which uses recycled materials for a very high percentage.

< p > the recommended recycled fiber mainly includes coffee charcoal polyester recycled fiber and heteromorphic polyester recycled fiber.

Take coffee charcoal polyester recycled fiber as an example: the common coffee carbon fibers, using coffee grounds as raw materials, are calcined at high temperature to make the crystal phase and pores of coffee grounds present the best state, grinding into nanoscale powders, and using special technology to make coffee charcoal masterbatch, and combine the corresponding key processes such as drying, spinning and drafting to form the final shape of the fiber.

Coffee carbon fiber at the same time has three kinds of heating and warming function: heat storage and warmth retention function, moisture absorption and heating function, far infrared heating and warmth retention function.

The polyester used here is regenerated polyester, which has the same product quality but is more environmentally friendly.

< /p >

< p > there are mainly two kinds of production routes for regenerated fiber: first, recycling materials such as bottle material, polyester waste silk and so on, through direct granulating and granulating, and physical recovery; two, using the reversibility of the condensation process of polyester polycondensate, by chemical method, the recovered polyester can be polymerized to form monomers, and then can be condensed into high-quality fiber grade polyester chips for spinning.

The latter method is highly regarded. By recovering the recovered polyester products to the molecular level, the mixture of dyes and other small mixtures can be removed, and the precursor with the same quality from the oil derived polyester products can be regenerated.

Unlike conventional recycled polyester, which is mainly made from raw bottle flakes, the recycling method can use leftovers and waste clothing in textile production.

< /p >

< p > recycling of waste bottles is mainly used for producing regenerated flakes, regenerated staple fibers and regenerated filaments.

Technically, regeneration bottles are difficult to regenerate filaments, and regenerated filament is difficult to regenerate staple fibers.

In China, BOTTLE VASE recycling industry is limited to authorized enterprises only. The technology level of regenerated filament represents the technical level of physical recovery to a large extent.

The production of 1 tons of recycled polyester filament can save 1.5 tons of oil, which is equivalent to 85% of energy saving and can reduce 3.2 tons of carbon dioxide emissions.

According to China's annual production capacity of 3 million 500 thousand tons of recycled filament, the regenerated polyester filament industry saves 5 million 250 thousand tons of oil resources per year and reduces carbon dioxide emissions by 11 million 200 thousand tons.

Therefore, under the current trend of environmental protection, the development of recycled polyester filament has good economic and social value.

Shandong Long Fu ring energy Polytron Technologies Inc is now using recycled polyester filament POY, DTY, FDY and polyester industrial yarn to produce large-scale recycled fibers such as polyester filament and so on. The second floor general manager, Dali Gang Li, said that the carpet made of recycled polyester filament has entered IKEA and promoted the development of recycled products.

< p > with the continuous development and progress of recycled fiber, its application scope has been extended to clothing, home textiles, industrial and other fields, such as carpet, bedding, or blended with other fibers for clothing, but also for filler and geotextile and insulation nonwovens and other fields.

For example, the regenerated polyester FDY can be made into blanket bottom silk, Oxford cloth, wrapping cloth, or silk like fabric. The regenerated polyester DTY can be blended with cotton, wool, hemp and chemical fiber to produce various specifications of knitted and woven fabrics, which can be used for making jackets, casual wear, sheets, towels, socks and so on.

Recycled polyester industrial filament is mainly used for tire cord, conveyor belt, canvas and so on.

Recycled polyester staple fiber is mainly used for automotive interior, shading products, and toys, sofa and other filling fibers.

The regenerated polypropylene fiber industrial filament has the characteristics of high color fastness, stable performance, strong toughness, anti aging, abrasion resistance, corrosion resistance and low cost. It can be used to produce polypropylene tapes, polypropylene fabric and some other derivatives.

< /p >

< p > in addition to conventional uses, the recycled polyester fiber recommended by the 2014/2015 fiber fashion trend has achieved a functional upgrade.

Three the leaf shaped recycled polyester filament can be used for curtain, garment and T-shirt. It has a good anti perspective function, and has strong absorption of sweat, rapid diffusion ability, and can achieve the effect of not easy to adhere after sweating.

Spiral regenerated polyester filament can be used in school uniform and sportswear. It has good gloss, good elasticity and high strength, durable and good sweat absorption and quick drying.
