The Production Process Of Non Dyeing Fiber Is Environmentally Friendly.

< p > the term "natural beauty" is used to describe unstained fiber.

Non dyed fibers are produced by coloring technology of raw liquid, < a href= "//www.sjfzxm.com/news/index_c.asp" > colored fiber < /a >, which not only reduces printing and dyeing process, saves energy and reduces emissions, but also has friendly and friendly colors to fabrics in the consumption and use of fiber products.

The process of non dyeing fiber in its whole production process meets the requirements of environmental protection in today's world.

In the current fashion that is in line with green environmental protection is the fashion trend, bright colored non dyed fibers undoubtedly become the favorite of fashion.

< p > technical support supports the concept of environmental protection < /p >

< p > current conventional fiber coloring is mostly done with yarn dyeing, with long process, high loss and high cost, and the product has chromatic aberration and low color fastness.

The yarn is also easy to fuzz and produce defects during dyeing.

Dyeing process also consumes a lot of water resources and produces a lot of wastewater that needs to be treated.

If it is white cloth, in the printing and dyeing and finishing links will also produce the above pollution.

< /p >

< p > however, the pursuit of bright colors is less than a href= "//www.sjfzxm.com/news/index_f.asp" > fabric > /a > clothing should have the personality.

The contradiction between them has aroused considerable controversy in the industry.

Fabric clothing can not be stored in a single color, but a considerable number of environmentalists are opposed to all kinds of dyed textiles.

Therefore, the promotion of the coloring technology of raw liquid is very bright.

< /p >

< p > at present, non dyed fibers have expanded from non dyed polyester to nylon, viscose and vinylon.

Non dyed polyester and nylon are produced by melt coloring directly before spinning.

The coloring of non dyed viscose and vinylon fibers before spinning is mixed evenly and dispersed into the spinning solution before the spinneret.

According to the spinning process, non dyed polyester and nylon can be divided into slice spinning method and melt direct spinning method. According to the different coloring materials, it can be divided into masterbatch method and mother liquor method.

The coloring process of non dyed polyester and nylon must be passed through pigment preparation, accurate metering, mixing melting or injection mixing, and high efficiency dispersing.

In the production process, non dyed fibers can omit most dyeing and finishing processes, reduce carbon dioxide and COD emissions, save water and chemicals, achieve a high degree of integration of color and clean production, and lead the modern textile industry into a "no dye low dye" era.

< /p >

< p > multiple advantages and application promotion < /p >

< p > in fact, the coloring technology of chemical fiber raw liquid is almost invented at the same time with chemical fiber.

The industrialization of both industries is almost synchronous.

But in the past, due to the heat and chemical technology problems in the production of non dyeing fiber, the development was restricted.

Moreover, compared with printing and dyeing products, there are problems such as incomplete chromatogram, lack of bright coloring, no deep dyeing, difficulty in pition color matching, etc.

However, with the technological progress of dyes and pigments, especially the development of fine grinding, dispersing agents, heat resistant materials (raw materials and dyestuff) technology and engineering, the application of coloring technology for chemical fiber raw liquor is gradually expanding, and the application of product range is more extensive.

According to the person in charge of Jiangsu Sheng Hong Polytron Technologies Inc, at present, polyester is added with color masterbatch, polyester has its own colour and lustre, and its gloss is good, and its color fastness is high.

Moreover, the fabric made of it has bright colors and high color fastness, and has no difference from the application field of conventional dyed fabrics.

< /p >

< p > and non dyed fibers have cost advantages.

Zhejiang Huhua new material Limited by Share Ltd, a leading product of multicolored green textile materials, focuses on the R & D, production and sales of non dyed fibers.

The company's relevant person in charge told reporters that he said that the polyester yarn on the surface of the product looked more expensive than ordinary dyed yarn, but the overall calculation still had cost advantages.

He made a comparison, assuming that Hua Xin's products are 13000 yuan / ton, the conventional yarn is 11000 yuan / ton, their products have been coloured, and the cost of conventional yarn dyeing and product turnover will add up to more than 2000 yuan.

The cost advantage of products is obvious.

< /p >

< p > in addition, we should deal with the trade barriers launched in the name of environmental protection in international trade.

Yuxin Group official said that as people pay more and more attention to ecological and environmental protection, the international control of heavy metal content of dyed products is increasingly stringent, and the developed countries have a high demand for various fastness of dyed products.

Acid dyes and metal complex dyes all contain heavy metal ions. Traditional dyeing technology can not meet the high quality requirements of textile market.

The research and development of non dyeing fiber, using organic coloring materials and innovative spinning equipment and technology, ensure the dispersion efficiency and do not affect the fiber performance index.

The official said that Yuxin's non dyed nylon fiber produced by direct spinning yarn technology can directly replace dyed yarn, which has been widely used in knitted garments, socks, ribbon, gloves, fancy core spun yarn, weaving and so on.

< /p >

< p > colourless viscose fiber coloring is relatively easy and bright color is widely recognized by the market.

Sanyou color fiber is one of the six categories of products of Tangshan Sanyou chemical fiber company. The brand product is made of high quality cotton, wood pulp and bamboo pulp.

According to the person in charge of the company, at present, the company's product color has more than 40 species, and can also be allocated according to the user's samples of the corresponding color.

< p > alliance form strengthens industrial influence < /p >

< p > the yield of non staining fiber has made great progress during the period of "eleven" five.

The total amount of dyed fibers in the raw liquor increased from 114.8 tons in 2005 to 2 million 422 thousand tons in 2010, accounting for 7.8% of the total chemical fiber at that time.

Entering the "12th Five-Year", the non dyeing fiber industry shoulders the heavy responsibility of the chemical fiber industry from the source of energy conservation and emission reduction, cleaner production, environmental friendly, < a href= "//www.sjfzxm.com/news/index_c.asp" > low carbon economy < /a > sustainable development.

More and more enterprises are involved in R & D, production, marketing and promotion of non dyeing fiber.

< /p >

< p > June 2012, the Chinese Textile Information Center and the national textile product development center, together with the China Chemical Fiber Industry Association, the China clothing association and the China Household Textile Industry Association, joined the 20 enterprises such as Jiangsu Xia Ke environmental protection color spinning Limited by Share Ltd and Heng Tian Enterprise Co., Ltd. to set up the "China Green non dyed textile Innovation Alliance".

It should be noted that with the cooperation between the upstream and downstream industries, there is bound to be a wave of unstained fiber in the terminal market.

The environment-friendly fashion concept of non staining fiber will also be familiar to ordinary consumers and pass on from mouth to mouth.
