Abstract

The invention relates to a PBT / PET blending imitated human hair fiber and a preparing method of the PBT / PET blending imitated human hair fiber. According to the preparing method of the PBT / PET blending imitated human hair fiber, PBT and color master batches are dried and uniformly mixed and then form a strip through a double-screw granulator, sized dicing is carried out on the strip to form color master slices, PET and the color master slices are dried, and then the PET, the color master slices and plasticizer are fused and extruded to form a spinning fused solution; the spinning fused solution enters a raw material pipeline inside a spinning box body from a screw machine head through a bending pipe, is pressurized by a metering pump, is squeezed out through a spinning assembly, passes a spinning channel and is slowly cooled by cross air blow; oil is applied to the slowly cooled spinning fused solution and the spinning fused solution is wound to form a nascent fiber; the nascent fiber is preheated and primarily stretched; tensioning heat setting and cooling are carried out on the nascent fiber to obtain the PBT / PET blending imitated human hair fiber. By means of the preparing method of the PBT / PET blending imitated human hair fiber, the PBT and the PET are blended through a specific preparing technology, dependency of the PBT fiber on temperatures is reduced after the PBT and the PET are blended, and the PBT / PET blending imitated human hair fiber reserves a soft hand feel, hygroscopicity, abrasive resistance and good crimp tendency of the PBT fiber and has the advantage of good dyeing property, and the PBT fiber is more widely applied to the imitated human hair fiber.

Description

[technical field] [0001] The invention belongs to the field of preparation of imitation human hair fibers, and relates to a PBT / PET blend imitation human hair fiber and a preparation method thereof. [Background technique] [0002] PET is the abbreviation of polyethylene terephthalate. PET fiber has a relatively high melting point, good heat resistance and heat insulation; it has excellent light resistance, but the hygroscopicity and dyeability of PET fiber are poor. Resilience is not ideal. [0003] PBT is the abbreviation of polybutylene terephthalate. PBT fiber has good durability, dimensional stability and good elasticity, and the elasticity is not affected by humidity; PBT fiber and its products are soft to the touch and hygroscopic. , good wear resistance and fiber curling, and has good dyeing performance; but the thermal deformation temperature of PBT fiber is low, the strength of PBT fiber is highly dependent on temperature, and the price of PBT fiber is much higher ...
