Abstract

The invention discloses a meshing twin-screw spinning pearl functional fiber and a manufacturing process thereof. A formula of the spinning pearl functional fiber by weight is as follows: 94-99% of melt spinning slices; 1-6% of pearl powder having average particle diameter less than 1mum; 0.1-3% of a surfactant and 0.1-3% of an antioxidant. The process comprises the following steps: the materials are placed in a mixer according to component proportions, added with the surfactant and the antioxidant 1010, then the mixture obtained is sent to an meshing twin-screw machine to be fused and mixed after being kneaded in the mixer, then is sent to a spinning manifold by the connection of a flange bend to directly spin, and a blending melt is spun from a spinneret plate through a spinning pack, and is wound into primary pearl functional fiber raw silk after cooling blow. Then the primary raw silk is subject to twice stretching and heat setting in packing or a single cylinder according to a filament or staple fiber post-processing procedure. Primary stretching of the filament is carried out on a hot disk, and secondary stretching of the filament is carried out on a hot plate; the primary stretching of the staple fiber is carried out in oil bath, and the secondary stretching is carried out by superheated steam. The manufacturing process is applicable to spinning pearl functional fibers.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to an intermeshed twin-screw spinning pearl functional fiber and a manufacturing process thereof. Background technique [0002] The existing technology of spinning pearl functional fibers and fabrics thereof has the following two methods. One is that the Chinese patent application number is: 021038902, which uses polymer chips and pearl powder to melt blend and spin into pearl powder functional masterbatch, and then blends and spins with polymer chips. The disadvantage of this method is that the pearl powder has been processed twice at high temperature, which will not only degrade the pearl powder in high temperature and affect its effectiveness, but also continuously rotate and tumbling in the drum when the slices are dried, sticking Attached to the inner surface of the drum, or sucked in vacuum drying, in addition to possibly affecting the equipment, it also wastes pearl powder...
