General Specification and Properties of Polyester Fiber

Polyester fiber of our plant is produced by modern technology of Neumag (Germany)

Polyester fiber has many positive properties meeting almost all requirements for textile fabric
· High mechanical stability
· High thermal stability; test in hot atmosphere of 180oC where shrinkage is about 4±2%
· No reduction of durability in wet atmosphere, high hygroscopicity therefore protecting fiber from shrinkage, crease and wrinkle
Application
Polyester fiber of our factory has low index, round cross cut, semi-dull color – specification of polyester fiber which is used as feed for textile and garment industry. Polyester fiber can be mixed with cotton (create TC or CVC), viscose (create TR) to produce high quality garment.
