Polyester-based mixed fibre spinning

Abstract

A combined filament yarn made by the following way:Cation dyeability polyester(CDP) and polyethylene terephthalate(PET)were spit out by separate die-spinning nozzles on the same board and they were wind to form the yarn. The combined filament yarn composed with 40-70% CDP and PET the rest by weight percentage. Textile made by this kind of yarn is tender, fluff-resistant and shows various styles.

Description

Technical field: [0001] The invention relates to a filament, which is a mixed filament yarn. Background technique: [0002] As we all know, as one of the main varieties of synthetic fibers, polyester fiber is widely used in clothing fabrics and other non-clothing fields. However, because the polyester molecular chains are tightly gathered, the crystallinity and orientation are relatively high, the polarity is small, and the lack of hydrophilicity, there is no gap between the molecular chains that can properly accommodate the dye molecules, so the dye molecules cannot easily penetrate into the fiber. The dyeability is poor, and there are few types of dyes that can be used. Polyester fibers can only be dyed with disperse dye carriers, high temperature dyeing, and hot melt dyeing. In recent years, many cationic dyeable modified polyesters have appeared on the market. Although the dyeing problem has been improved, there is still the problem of monotonous dyeing of the fabric. It is p...

Problems solved by technology

This type of polyester blended yarn mainly has the disadvantages of relatively single fiber cross-section shape, difficult to change total fineness and large fineness, poor dyeing uniformity, and seriously affects subsequent weaving.
