China Recycled polyester bright pre-crystallization chips Factory

From January to June 2022, a total of 1.628 million tons of domestic polyester filaments were exported, a slight decrease of 0.3% year-on-year. Among them, the export in the first quarter was 781,000 tons, a year-on-year decrease of 13.5% due to the high base last year; the export in the second quarter was 847,000 tons, a year-on-year increase of 16.1%, mainly due to the explosive growth of exports from May to June.

After the first stage of polymer production in the melt phase, the product stream divides into two different application areas which are mainly textile applications and packaging applications. In the following table, the main applications of textile and packaging of polyester are listed.

Recycled polyester is a sustainable yarn. It offsets use of crude oil, conserving precious natural resources & energy. The difference between virgin polyester and recycled polyester is that the former is created from scratch using fossil fuels, whereas the latter relies on post-consumer plastic. Wasted polyester is toxic to the earth. Among the trend is recycled plastic bottles being turned into fabrics which are considered sustainable to keep from them piling in the landfills. From a strictly environmental point of view, recycled polyester is more sustainable than virgin polyester.

Recycled polyester is just as good as virgin polyester but takes less resources to make - Recycled polyester is almost the same as virgin polyester in terms of quality, but its production requires 59 percent less energy compared to virgin polyester.

Compared with nylon yarn, recycled polyester yarn has a large market due to its low cost and good performance. There are many different varieties of recycled polyester fibers, such as ordinary fibers, hollow fibers, triangular fibers, flame-retardant fibers, etc., which are now generally used in the filler industry of furniture and toys, bedding, clothing industry, needle-punched cotton industry, and stitch-bonded fabrics industry, etc. Besides, the application field of recycled polyester yarn is similar to that of virgin polyester yarn. It is widely used in suspenders, shirts, skirts, children's clothing, silk scarves, cheongsam, ties, handkerchiefs, home textiles, curtains, pajamas, bows, gift bags, sleeves, fashion umbrellas, pillowcases, pillows, etc. It is most often used to produce textiles that require GRS certification, or used together with other type of yarn to manufacture core spun yarn or blended yarn.

Currently, mechanical recycling is the most common form of polyester recycling as it’s a simpler process and more easily sourced. The chemical recycling process uses more chemicals and energy than mechanical recycling, posing a question as to whether this toll on the environment is acceptable. On the flip side, it can create a polyester material that is supposedly of equal quality to virgin polyester and has the potential to close the loop on polyester recycling. Although not available on a wide scale yet, there are some suppliers offering this method at a higher cost to mechanical recycling, and we’ll likely see this method develop with less environmental impact in the near future.
