Microfiber is also called fine-denier fibers or ultra-fine fiber. Generally, it refers to fiber with a fineness of 0.3 deniers (5 microns in diameter) or less. Its fineness is 1/200 of human hair and 1/20 of ordinary chemical fiber. Its strength is 5 times of ordinary fiber (durability). And its absorption capacity, water absorption speed,

Recycled Cationic Dyeable Chip

Recycled Cationic Dyeable Chip is called Eco-friendly polymer. By adopting a unique production process, Recycled Cationic Dyeable Chip is made from recycled bottle flakes. These flakes are made into recycled PTA. And PTA and MEG have transesterification and polymerization reaction. During the process, the SO3NA group is added to the macromolecule chain. Then we get recycled cationic dyeable polymer

Desizing Methods

Desizing methods include enzymatic desizing, oxidative desizing, acid steeping, rot steeping (use of bacteria), alkali desizing (with hot caustic soda treatment), hot washing with detergents. Why need sizing and desizing? The sizing process is carried out before weaving to increase the abrasion resistance, smoothness, and antistatic properties of warp yarn. Nowadays, warp yarn sizing is

Physical Properties of Polyester Chips

The physical properties of polyester chips are closely related to their quality. Except for intrinsic viscosity (IV), what are other important physical properties of polyester chips? Intrinsic Viscosity (IV) Generally speaking, the IV for textile-grade PET chips is 0.645. The viscosity is used to characterize the molecular weight of the polymer in industry. IV measurement

Low Melt Polyester for Bi-component Fiber

Low Melt Polyester for Bi-component Fiber This paper focuses on Low Melt Polyester for single-component or bi-component low-melting polyester, which can be used for bonding fibers. But comparatively speaking, two-component fibers are more economical in low-melting polyester dosage. And the core layer is the main fiber composition, more conducive to maintaining the mechanical properties of

What is Cationic Polyester?

What is Cationic Polyester? Cationic Polyester refers to cationic dyed (dyeable) polyester. The abbreviation of cationic polyester is PBT or CDP. PBT is a specialty or modified polyester, which is produced by charging macromolecules with the cationic dyeable group. As a result, CDP can be dyed with cationic dyes at the temperature of 110℃. The
