Corespun polyester threads is a combination of filament polyester core thread wound in polyester. It is also called "Poly-core spun-poly", "P/P" and "PC/SP" threads. The advantage of using core spun polyester thread such as OMNI or OMNI-V is that the filament core increases the strength. The matte finish and strong tensile strength of OMNI and OMNI-V make them a favorite for sewing. Filament polyester is a continuous fiber thread. Some people hear the term filament and mistakenly think it is monofilament. The monofilament that looks like a fishing line is just one type of thin thread. It is a single (single) strand. MonoPoly is an example of monofilament thread. Other filaments are multiple filaments, consisting of two or three strands twisted together. This is the largest category of filament polyester. The multifilament strands are smooth and hairless, but opaque. The advantage of lint-free is that the machine is cleaner and less maintenance. The bottom ...

Polyester can be completely recycled or made from recycled plastic. PTA, MEG, PET chips and recycled PET bottle flakes are the main raw materials used to produce polyester staple fibers . The polymer produced from the above-mentioned raw materials is melt-spun to allow rapid cooling. The filament bundles obtained by melt spinning technology are called tows, which are crimped and stretched first, and then cut into a fixed length. The cut fiber thus obtained is called polyester staple fiber. It is also possible to produce polyester staple fiber without using raw oil stocks. All new polyester fabrics come from recycled plastics. For example, Repreve is a certified recycled fabric made from recycled plastic bottles. It is usually used in swimwear and sportswear. Manufacturers, such as Eco Intelligent Polyester, have been committed to recycling old polyester garments and plastic bottles to make new polyester. As people are more and more aware of the impact of plastics on the environment, di...
