Multiple benefits of recycling


  

Regenerated filament polyester fiber

It can be divided into several varieties.

Among them, the regenerated FDY filament polyester fiber can be used as blanket, silk cloth, Oxford cloth, wrapped cloth and silk like fabric.

Regenerated DTY filament polyester fiber can also be blended with cotton, wool, linen, silk and chemical fiber, used for weaving or knitting, producing various specifications of woven fabrics and knitted fabrics. It can be used for making jackets, casual wear, suit suits, shirts, underwear, T-shirts and towels, bath towels, sheets, etc.

Regenerated filament (industrial) polyester fiber is mainly used for tire cord, conveyor belt, canvas, car seat belt and conveyor belt.


The production of recycled filament polyester fiber which accords with the standard of national primary filament polyester fiber is more commonly used for recycling of waste polyester.

This will not only help to restructure China's petrochemical raw materials, reduce the dependence on oil resources, effectively replenish raw material supply, but also save land, solve the problem of grain and cotton competition, reduce environmental pollution, achieve low carbon economy and green economy.


Speed up expansion of scale production


Act as

low-carbon economy

And the representative of green economy, regenerated filament polyester fiber has been developing rapidly in recent years by virtue of its green, sustainable characteristics and broad market prospects.


Long Fu ring Polytron Technologies Inc, one of the 350 key industrial enterprises in Shandong Province, has always attached great importance to the development and production of industrial functional and differential high value added products in the development of new products.


After keen sensing of the development space of new fibers, dragon Fu began to tackle technical problems in 2007, and has independently developed three core technological achievements: "making waste polyester bottle chips to produce polyester filament", "using waste polyester bottles to produce polyester industrial yarn" and "using waste polyester bottles to produce polyester full draft yarn".


Through the appraisal of provincial scientific and technological achievements and the ministerial level appraisal organized by the Federation of textile industry, the overall technical level has reached the international advanced level and has filled the gap in China.

Among them, the self-developed technology of liquid phase viscosity increasing and viscosity increasing homogenization of waste polyester has even reached the advanced level in the world.


According to Di Gangli, deputy general manager of Long Fu, at present, the long recycled polyester filament made by Long Fu has made a major breakthrough. It has become the first enterprise to realize large-scale production in China, and has built the world's only complete circular economy industrial chain, which integrates waste polyester treatment, regenerated polyester filament production and regenerated polyester fabric weaving.


"Now we have formed a capacity of 80 thousand tons of regenerated polyester filament and 30 thousand tons of recycled polyester blankets, and become the leading enterprises in the domestic recycling of waste polyester, which are of great influence both at home and abroad."

Said Di Gang Li.


Catching up with the development vision of advanced level


With the improvement of recycling and processing technology, recycled polyester has broken the gap between big and small chemical fibers in the past.

Regenerated product

The gradual improvement of quality has gradually weakened the advantages of primary spinning. In addition, the regenerative polyester industry has a higher input output ratio than the original polyester industry, and the recycled products gradually seize the market of the original polyester fiber.

In terms of product performance, there are now some or even all of the original polyester products regenerated polyester products.


In terms of raw material prices, the gap between the price of raw silk chips and the price of raw sliced chips is also shrinking. The original price difference is 2000 yuan / ton, and the difference is 1000 yuan / ton.

With the continuous expansion of recycled polyester in the field of primary polyester, the growth of recycled polyester industry has become an important development force in the polyester industry.


During the "12th Five-Year" period, China's regenerated polyester production capacity will reach 8 million 300 thousand tons / year, and output will be 6 million tons / year.

Most of the original polyester products are used for spinning and weaving. The use of recycled polyester products shows obvious diversification trend and is still expanding.

At present, the application market of recycled polyester products covers non-woven fabrics, carpets, home textiles, automobile textiles and other fields, and nearly 100 kinds of products have been produced.


In addition, non fiber application areas are developing towards diversification and high technology content, such as bottles, tablets and films for food grade packaging, all kinds of packaging trays, plastic steel strips and injection molded parts, as well as engineering plastics, and other high-end products for non food packaging purposes.


"However, at present, there is a certain gap between China's regenerated chemical fiber products and the world's advanced level in terms of raw materials, varieties, technologies, production scale and product application.

In particular, the research and development capabilities of functional and differentiated recycled fiber products are insufficient, and we need to further expand the application areas of products. "

Said Di Gang Li.
