Recycled polyester filament yarn is an important part of recycled polyester yarns. It responds to the call of environmental protection, and NEXTILE is committed to developing this industry. This article will take you to learn more about it.

Comparison between reclaimed and virgin polyester filament
The future development direction of recycled polyester filament yarn
The average breaking strength of each polyester filament has little difference, and the average breaking strength of black recycled polyester filament yarn is slightly lower. The average elongation at break of recycled polyester filament yarn is much higher than that of ordinary polyester filament, and the average elongation at break of black recycled polyester filament yarn is more than twice that of original polyester filament. The coefficient of variation of average breaking strength and average breaking elongation of recycled polyester filament yarn is smaller than that of virgin polyester filament, and the coefficient of variation of black recycled polyester filament yarn is very stable.
(1) Reduce costs
The development and utilization of recycled polyester filament yarn plays a positive role in protecting the environment and saving energy. However, there is a big gap between recycled polyester filament yarn and virgin polyester filament in terms of technology development, cost and quality. Therefore, it is necessary to greatly reduce the spinning cost in order to promote the expansion. The price of 333.3dtex / 96F for DTY regenerated polyester filament is approximately RMB 0.78 million per ton. The price of 166.7dtex / 72F for chemical regenerated polyester filament is approximately RMB 23,000 per ton. The price of general polyester filament 333.3dtex / 96F is roughly 0.76 million yuan per ton, and the price of 166.7dtex / 72F is roughly 0.82 million yuan per ton. Due to the collapse of oil price, recycled polyester filament yarn has lost its price advantage, but its social benefits of environmental protection have not disappeared. Therefore, it is necessary to further promote the development of the recycled filament processing industry by relying on the concept of environmental protection first of the government and consumers.
(2) Improve dyeing properties
The color consistency of polyester filament regenerated by physical method has always been the main problem restricting the application of products, especially for light fabrics. It is usually overcome by adding fluorescent agent in the process of filament production in a customized way.
(3) Add color silk processing
At present, black recycled polyester filament yarn has made a breakthrough in blackout curtains, bags, umbrella cloth and other products, and the development of color recycled polyester filament yarn will be the future development direction.
(4) Strengthen the development of differentiated functional recycled polyester filament yarn products
In order to further expand the application of recycled polyester filament yarn yarn, it is necessary to strengthen the development of differentiated and functional products, from the past simple and extensive nonwovens to wearable high-end products, and increase the research and development of high value-added functional products such as flame retardant, moisture absorption and sweat drainage. According to the characteristics of different downstream demands, enterprises have developed four categories of recycled polyester filament yarn yarn series products for garment fabric, decorative fabric, garment accessories and industrial use, including bottle spinning (POY, FDY, DTY) and medium and high strength filament. The long filament grid has 83.3dtex (36F~76F). 166.7dtex (36F~144F), 333.3dtex (96F~288F), 500dtex (96F~288F), 666.7dtex (96F~288F). Some enterprises have developed industrial silk, FDY and other recycled polyester filament yarn silk products, and launched new recycled textile products such as interwoven fine blankets, pineapple blankets, pineapple carpets, pineapple cushion and home textile quilt.
The development and development of recycled polyester filament yarn is an important direction for the future of textiles, and NEXTILE will continue to develop related industries.
