The Application Of Recycled Polyester Fiber Remains To Be Improved.

< p > as a new force of regenerative polyester a href= "//www.sjfzxm.com/news/index_c.asp" > fiber industry < /a >, the Polytron Technologies Inc, which is mainly engaged in resources recycling, energy saving, environmental protection and low carbon type, has formed an indissoluble bond with regeneration technology since its inception.

After years of efforts and accumulation, the technology of "liquid phase thickening / homogenizing direct spinning industry of waste PET bottle", "a" href= "//www.sjfzxm.com/news/index_c.asp" > polyester filament < /a > key technology and equipment development "was finally awarded the first prize of" textile light "science and technology progress in 2012, in cooperation with China's a target=" _blank "href=" //www.sjfzxm.com/ "> textile science and Technology Research Institute, Shanghai polyyou Chemical Co., Ltd., Beijing Zhongli Machine Engineering Technology Co., Ltd. and Yangzhou Zhicheng Chemical Technology Co., Ltd.

This is a response to Long Fu ring for many years in the regenerated polyester fiber industry. It is also a great gift to the regenerated polyester fiber industry.

< /p >

< p > < strong > lasted for several years only to make regeneration better. < /strong > /p >

< p > polyester has become the most important raw material for bottled water, food and other packaging materials due to its characteristics of light weight and pparency.

In recent years, China has accumulated 25 million tons of polyester bottle social stock, most of which are disposable. If it is not recycled, it will not only cause waste of resources, but also seriously pollute the environment.

In this case, the existence of recycled polyester fiber industry can be said to solve the urgent problem of polyester recycling.

< /p >

< p > such an industry with unlimited potential for development has been developing for more than 20 years since its appearance.

Long Fu ring, located in the Qilu land, was registered in 2006 and has been in the industry for many years.

However, whether for the long Fu ring or the whole regenerated polyester fiber industry, the waste bottle flakes are irregular, contain lots of impurities and have large viscosity differences, resulting in the large fluctuation of the head pressure, poor filtration performance, more spinning breakage and poor spinnability in the fiber production process.

< /p >

< p > the leadership of the Dragon Fu ring can be seen in the eyes and anxious.

"How to overcome these problems and help companies and industries better move forward" has become a big question that lingers in their minds.

Dun Gang Li, vice general manager of Long Fu ring, told reporters that with this problem, with the determination to overcome difficulties, in 2009, long Fu ring could cooperate with China Textile Science Research Institute, Shanghai poly friend Chemical Co., Ltd., Beijing Zhongli Machine Engineering Technology Co., Ltd. and Yangzhou Zhicheng Chemical Technology Co., Ltd.

< p > < strong > standardizing the management of liquid phase visbreaking has become a new breakthrough < /strong > < /p >

< p > for Dragon Fu ring, the days of technical research and development are the days of standardized management and the most important teamwork day.

The success of technology is not easy.

Team cooperation is a valuable asset for our R & D team.

At that time, the technicians of our dragon Fu would put forward the idea on the basis of all kinds of problems. Then experts from the China Academy of textile science and technology should make specific designs according to these ideas to help us improve.

Moreover, the role of standardized management is quite large. It is on these bases that we have made fundamental breakthroughs in tackling liquid viscosity increasing technology. "

Di Gangli said.

< /p >

< p > it is reported that "waste polyester bottle liquid phase viscosity increasing / homogenizing direct spinning industry" < a href= "//www.sjfzxm.com/news/" > polyester filament > /a > key technology and equipment development "project aimed at the characteristics of waste PET bottle slices, through research and development of bottle sheet screening, smashing, cleaning, mixing, drying, screw melting, filtration, liquid phase thickening / homogenization, spinning, and so on, eventually forming liquid phase viscose direct spinning polyester industrial yarn, liquid homogenizing direct spinning FDY polyester filament and direct spinning POY polyester filament technology and equipment complete set of technology.

Moreover, we have focused on the development of tile pre blocking device, anti bridging and drying device, large compression ratio and large aspect ratio screw extruder, double stage filtration device, horizontal self-cleaning single shaft liquid viscosity increasing reactor, squirrel cage stirring homogenizing reactor, small energy-saving spinning box, special component, multi-stage stretching heat setting device, etc., which can meet the production needs of different varieties and various specifications products.

< /p >

< p > "we first created and formed a 5000 ton / year scale direct spinning and regenerated polyester industrial yarn production line in the world. We first established and formed a 30 thousand ton / year scale direct spinning regeneration FDY < a href=" //www.sjfzxm.com "> filament production line < /a >, and accumulated the 170 thousand ton / year scale direct spinning regenerated POY filament production line.

Moreover, the industrial yarn produced by various indicators has reached the industry standard of spinning the related products using the original chips, which can be said to be quite successful.

Di Gang Li said.

The benefit is significant < /p >

< p > < strong > application needs to be improved < /strong > < /p >

< p > Long Fu ring can make use of the waste polyester bottle direct spinning industry to use differential regenerated polyester filament to overcome the worldwide difficulties of waste polyester not directly producing polyester filament, and end the history of waste polyester can only produce polyester staple fiber, which fills the gap in domestic.

Moreover, the successful development of the project has realized the high value utilization of waste PET bottles, and played an effective role in reducing the dependence on oil, establishing an environment-friendly, resource conserving society and developing circular economy. It is in line with the development mode of low carbon economy and the strategic policy of national sustainable development.

< /p >

In this case, the Dragon Fu ring has built the world's only circular economy industrial chain from waste polyester recycling, bottle flake cleaning, spinning to weaving weaving. The regenerated polyester filament products are widely used in many fields, such as industry and civilian, and have led to the development of a group of recycled a polyester blankets, including carpet, decorative cloth, conveyor belt, < a target= "_blank" href= "//www.sjfzxm.com/", "dress less than /a" fabric, a href= "//www.sjfzxm.com" > Industrial Cluster "/a", recycling 100 thousand tons of waste polyester every year, which has created considerable economic benefits, and has provided nearly 3000 jobs for the society. < p >

< /p >

"P >" we use self-produced regenerated FDY filament and POY filament as raw materials to produce weft knitted blankets and high-grade warp knitted blankets, which have been exported to over 20 countries and regions in the Middle East, Africa, Europe and the United States.

However, there are still difficulties and bottlenecks in the application field of such a technology. "

Di Gang Li said bluntly.

< /p >

< p > according to him, the high-end market of this technology has not yet been developed in terminal applications, mainly based on low-end products, and there is still a gap in quality between the original fibers and the original ones.

Quality is also the most important reason that restricts its development to high-end market.

On the other hand, there are many varieties of raw fiber in ultra fine denier, heterosexual and functional, and the varieties produced by regeneration technology are still few.
