Abstract

According to the invention, honeycomb structure polyester modified fibers can be obtained through copolymerization of low molecular weight PET (polyethylene terephthalates), monomers containing sulfuric acid groups, amino groups and amide groups, and an antistatic agent. The invention further comprises honeycomb structure polyester modified fiber pure/blended yarns and production technology thereof, wherein the blending weight ratio of honeycomb structure polyester modified fibers and other fibers is (40%-75%) to (25%-35%). The invention has the benefits as follows: the obtained honeycomb structure polyester modified fibers have high moisture absorption rate, high antistatic property, high anti-staining performance, high anti-pilling property and excellent flame resistance; on the premise of thorough comprehension of optimal optimum technology parameters, the honeycomb structure polyester modified fibers can be produced by adopting normal equipment of a cotton spinning mill; the produced honeycomb structure polyester modified fiber pure/blended yarns and back-end fabric products thereof can be used for development of high quality clothes and relevant products; pure spinning and blended spinning are different in style and have different characteristics.

Description

technical field [0001] The patent of the invention relates to the spinning process in textile engineering, specifically a pure spinning and blended yarn of polyester modified fiber with honeycomb structure and its production process. Background technique [0002] Ordinary polyester fiber has poor hygroscopicity, the moisture regain rate is 0.4-0.5% under standard conditions, and the moisture regain rate is 0.6-0.8% when the relative humidity is 100%, so the fiber performance does not change much under dry and wet conditions; Since the fiber has no hydrophilic groups and the molecules are tightly packed, it is difficult for the dye molecules to enter the interior and cannot be dyed by general methods; at the same time, the polyester fiber has high strength and good elastic recovery performance. The above-mentioned performance characteristics lead to poor wearing performance and dyeing performance of ordinary polyester fibers, and they are stiff and airy when used as underwear...
