Method for preparing fibers with performance of sheep wool and imitated wool fabric

Abstract

The invention relates to a method for preparing fibers with performance of sheep wool and an imitated wool fabric. The method for preparing the fibers comprises the following steps that: (1) full dull polyethylene terephthalate (PET) slices with TIO2 content of between 2.8 and 3.6 weight percent and intrinsic viscosity of between 0.662 and 0.668 are used as a first raw material; (2) water-solublePET slices are used as a second raw material, and the consumption of the water-soluble PET slices is 2 to 3 percent of the total weight of the fibers; (3) the master batch of a far infrared material is used as a third raw material, and the consumption of the master batch is 1.5 to 4 percent of the total weight of the fibers; (4) nano calcium titanate master batch is used as a fourth raw material,and the consumption of the master batch is 0.5 to 0.8 percent of the total weight of the fibers; and (5) the four raw materials are mixed uniformly in a mixing device and spun through a medium hole plate to form the fibers, and the fibers are prepared into the imitated wool fabric by warp knitting, weft knitting, alkali treatment, dyeing, finishing, sizing and drying. The function of the imitatedwool fabric is 80 to 82 percent similar to that of a wool fabric. Moreover, the method is simple and low in cost.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a preparation method of imitation sheep wool fiber. Background technique [0002] Sheep wool is a natural animal fiber. Wool fiber has the characteristics of good hygroscopicity, warmth retention, air permeability, strong elongation and strong resilience. The characteristics of wool determine its wide range of uses and the characteristics of being used for high-end clothing and carpets. However, wool as a carpet may increase the possibility of mites, which will affect the human body or people with allergies, so many wool-like products have emerged. . However, most of the current wool-like products are compounded with half of the materials to achieve some characteristics of animal hair, or to achieve moisture absorption, heat preservation, and quick-drying characteristics through the maintenance of hole patterns. However, similar appearance and performance are not Reach peopl...

Problems solved by technology

However, most of the current wool-like products are compounded with half of the materials to achieve some characteristics of animal hair, or to achieve moisture absorption, heat preservation, and quick-drying characteristics through the maintenance of hole patterns. However, similar appearance and performance are not Reach people's expected performance requirements of more than 80%. For example, the method disclosed in the Chinese invention patent application with the publication number CN101481831A is to use PTT as the first raw material and modified high-shrinkage polyester as the second raw material. Compounding on a DTY machine, Utilizing the different shrinkage properties of the two materials, the fiber has the effect of wool feeling, but the preparation method of the fiber is long, and the curling effect of wool cannot be realized from the perspective of appearance and nap feeling. Another example is the Chinese invention patent with publication number CN101144211A. Disclosed is a preparation method of differentiated fiber with wool-like effect, which is to use two kinds of raw materials to compound on a texturing machine through different potential internal stresses to form leather silk and core silk to achieve the wool-like effect. It achieves breathable performance through multi-deformation design

But when this method produces wool-like effect fibers and needs to realize the fabric of plush effect, it can't reflect the plush effect of animal fur and can't reflect the thermal insulation characteristics of animal fur
