High strength low shrinkage polyester filament
High strength low shrinkage polyester filament is a kind of synthetic fiber with special properties. High strength low shrinkage polyester filament is a chemical fiber made from polyethylene terephthalate (PET) through special spinning process and post-treatment. Its molecular structure contains a large number of ester groups, and the molecular chain arrangement is relatively regular, which makes it have high strength and stability.

Product Description
High strength low shrinkage polyester filament has high breaking strength, which is generally much higher than ordinary polyester filament. This makes it able to withstand large tensile force and not easy to break. It is suitable for occasions requiring high strength, such as industrial textiles, ropes, fishing nets, etc. The shrinkage rate is low at high temperature or under external force. Ordinary polyester filament may have large shrinkage at high temperature, while high-strength low shrinkage polyester filament can maintain a relatively stable size. This feature enables it to better maintain the shape and reduce the deformation and size deviation caused by shrinkage in the process of processing and use. The surface is smooth and has good wear resistance. It can withstand long-term friction and wear and prolong its service life. Therefore, it is often used to make items that need to withstand frequent friction, such as tire cord, conveyor belt, etc. It has good tolerance to most chemicals, is not easy to be eroded by acid and alkali and other chemicals, and can maintain stable performance in different chemical environments. After special treatment, it has certain anti ultraviolet ability and can be used in outdoor environment for a long time without aging and fading. It is suitable for outdoor textiles, such as sunshade cloth, tent, etc.
