    < p > in recent years, our country's < a target= "_blank" href= "http://www.91se91.com/" > strong > textile > /strong > /a > industry has developed rapidly. Waste silk, waste silk, waste a a, "/a", "waste", "waste", "cloth" and "waste" are increasing. Synthetic fiber plays an important role in the textile industry, especially in the rapid development of polyester industry. It brings scientific and technological progress and comfortable enjoyment to the production and life of mankind. The environmental pollution caused by various waste polyester products and polyester wastes is also increasing. < /p >
    < p > < strong > the production volume of recycled polyester fiber is the world's first < /strong > < /p >
    < p > experts pointed out that regenerative fibers are mainly divided into two categories: regenerated cellulose fibers and regenerated chemical fibers. Viscose fiber is the earliest regenerated fiber. After that, new regenerated cellulose fibers, such as Lyocell fiber, cellulose carbamate fiber, superconducting viscose fiber, kapok fiber and bamboo fiber, appeared. Polyester fiber accounts for about 70% of synthetic fiber, and the application of polyester in the bottle making industry is expanding rapidly. Therefore, regenerated chemical fiber is mainly regenerated polyester fiber. < /p >
    < p > China's recycled polyester industry has been developing for nearly thirty years. In 1987, Jilin textile Technology Development Company introduced the first regenerated fiber production line in China. In 1990s, the single screw spinning equipment mainly spanferred from Taiwan and Korea was used to produce low-grade needle punched nonwovens and yarns with foam material. In twenty-first Century, with the development of technology, gradually developing bottle flakes as the main raw materials or foam materials as auxiliary materials to produce regenerated polyester staple fiber, two dimensional hollow fiber, three dimensional crimp hollow fiber, regenerated polyester filament and polyester industrial yarn. Polytron Technologies Inc is currently using polyester bottle material to produce regenerated polyester filament POY, DTY, FDY and polyester industrial yarn. < /p >
    < p > in recent years, China's regenerated fiber industry has been developing rapidly, mainly in the southeast coastal area. Jiangsu and Zhejiang accounted for 72% of the total capacity of the country, while 10% of Guangdong and Fujian accounted for 10%, while the rest accounted for only 18%. In 2010, China's regenerated polyester fiber production capacity reached 6 million 200 thousand tons / year, and has become the world's largest producer of recycled polyester fiber. < /p >
    < p > regeneration of polyester fiber production process there are two main routes: first, the use of bottle material, polyester waste silk and other recycled materials through crushing and granulation direct spinning, known as physical recovery production method; two is the use of polyester polycondensate condensation process of reversible performance, through chemical methods to make recycled polyester depolymerized monomer, and then condensed into high-quality fiber grade polyester chip for spinning, known as chemical recovery production method. {page_break} < /p >
    < p > < strong > the overall quality of fiber has reached the international level < /strong > < /p >
    < p > > Beijing a target= "_blank" href= "http://www.91se91.com/" > strong > dress < /strong > /a > College Wang Rui pointed out that the accurate sorting of waste textiles is a difficult problem in the industry at present, and is also the focus of research. For different waste textiles, it is necessary to use different methods for effective sorting. For pure spinning products, manual sorting can be done directly. Blended products are designed according to the different composition and blending ratio of blending materials. < /p >
    < p > generally speaking, if accurate sorting is made, the cost of regenerated fiber will increase a lot, and some even cost more than raw fiber. Therefore, the recovery and utilization of waste textiles can be directly used for low-grade textiles, so that we do not need to distinguish colors. Two, we can broaden the application field of recycled fiber, and our thinking is not confined to the field of textiles only. For example, the use of waste textiles directly processed into ultrashort fibers, and then processed with other materials, made of composite materials, or directly used for filling materials. < /p >
    < p > what problems should be solved in the differentiation of recycled polyester fiber? Wang Rui believes that the main problem to solve in the current domestic regenerated polyester fiber differentiation is to improve the product mix and improve the proportion of high-end products. Foreign countries started earlier in the differentiation field of recycled polyester fibers, and our work in this area is relatively late. Coupled with technical constraints, our regenerated polyester fibers are mostly concentrated on low-end products. To enter the high-end field, recycled fiber must solve two problems: first, because the fibers in the waste textiles have many colors, so the regenerated fiber should solve the color problem, mainly to study the coloring problem of recycled fiber production, or how to make use of the original color problem. The uniformity of dyeing is a problem faced by the industry when the recycled fiber is dyed. The two is to study how to improve the quality and stability of recycled fiber. The quality uniformity of fibers made from waste textiles is also difficult to guarantee. To solve the two "uniformity" problem, recycled fiber will be able to move towards high-end fields. < /p >
    < p > Wang Rui finally said that in general, the research in the field of recycled fibers started earlier in foreign countries, and in recent years, the domestic development is relatively fast. With the increasing emphasis on the field in China and the increasing investment in this field, the overall quality of recycled fiber in China has not been much different from that in other countries. However, the quality and stability of recycled fibers in foreign countries are more excellent, and the equipment is more mature. The gap between China and foreign regenerated fibers is mainly reflected in the equipment. < /p >

    The Way For Printing And Dyeing Enterprises To Survive And Develop

    Under the situation of aggravated factor resources and weak market demand, some enterprises still focus on price fixing, capital mobilization and labor force sharing. The added value of products is not high, the brand awareness is not high, and the core competitiveness is not strong, which is not consistent with the demand and trend of enterprise development, especially to speed up the pformation and upgrading of county economy.
