Abstract

The invention relates to the field of chemical fiber differentiation, aims at solving the problems that a covered spandex yarn is difficult to process, troublesome to take care and excessive in elasticity and a person can feel suffocated when wearing clothes made from the covered spandex yarn and provides a hemp-feeling polyester coated fiber as well as a preparation method thereof. Fibers are obtained by compounding elastic compound polyester drawn yarns and polyester drawn yarns in a winding and coating way at an inlet of a hot box on elasticity enhancing equipment, and then high temperature deformation, setting and low-speed winding are carried out, so that the hemp-feeling polyester coated fiber is obtained. The hemp-feeling polyester coated fiber has the characteristics of excellent elasticity and elasticity recovery, unique hand feeling and gloss, pollution resistance, fluffiness, sunlight fastness, chlorine resistance and good moisture absorption and quick drying properties.

Description

technical field [0001] The invention relates to the field of chemical fiber differentiation, in particular to a polyester-coated fiber with hemp feeling and its preparation and application. Background technique [0002] Some properties of spandex fibers can no longer satisfy all customers, so more and more polyester factories have begun to develop polyester-like elastic fibers. The Chinese patent application number 201510411860.9 discloses a method for preparing a high-elastic covered yarn. The invention uses PBT / PET composite yarn as the main rib and polylactic acid as the coating layer. However, due to the core PBT / PET composite, Therefore, the elastic uniformity of the fiber is poor. The Chinese patent with application number 201410308219.8 discloses a kind of antibacterial elastic covered yarn, which uses spandex filament as the core filament and wraps antibacterial polyester fiber in the form of a spiral composite yarn. However, since the core layer is spandex filament...
