The recycled yarn is also called bottle flake polyester filament, mainly because its raw material is recycled PET bottle flake. We usually say that polyester filament is made of PTA and ethylene glycol as raw materials through polyethylene terephthalate (PET), a fiber-forming polymer made by esterification or transesterification and polycondensation. Fibers made by spinning and post-processing. Compared with melt-spun and slice-spun filaments, the quality of recycled filaments produced by domestic physical recycling bottle flakes is currently poor. It is difficult to produce high-quality fabrics, and only plays a role in replacing polyester filament in some low-end areas.
Recycled polyester yarn is processed by spinning such as waste bottle flakes, which not only expands new fiber resources, but also achieves energy saving and emission reduction, making reuse, regeneration and recycling a concept, a culture, a responsibility, a kind of fashion. Re-growing silk polyester fiber is an upgrade of products in the recycling industry, triggering a new product layout in the recycling industry. Expert comment: At present, my country's recycled chemical fiber products have a certain gap with the world's advanced level in raw materials, varieties, technology, production scale, product application and so on. In particular, the research and development capabilities of functional and differentiated recycled chemical fiber products are insufficient, and the application fields of products need to be further expanded.
