Problems solved by technology

[0003] However, rabbit velvet fiber has the following inherent weaknesses: 1. The scales are finer, the surface is smooth, the friction coefficient is small, the number of crimps is less, the strength is low, and the cohesion force is small, resulting in poor spinnability of rabbit velvet fiber, and it is difficult to process it into high-count number, high quality yarn
2. The scales move in both directions, and the product loses hair, lint, and pilling more seriously; it affects the style of the product and the ornamental value of the clothing
As a result, high-count, high-quality rabbit wool yarns have not yet been put on the market

Embodiment 1

[0037] Embodiment 1 A kind of 100% rabbit down specification is the semi-worsted rabbit down yarn of 80NM / 2D and processing method thereof

[0038] a. Raw material pretreatment: Put the raw rabbit down fiber into the cleaning reaction kettle, add water 20 times its weight, and stir and wash it for 0.5-1 hour at a temperature of 40-50°C; rinse, spin dry, and dry; after passing the inspection, Packaging and storage;

[0039] b. Oxidation and enzyme treatment: Put the clean and dry rabbit down fiber into the oxidation treatment reaction kettle, under stirring, add 30-50mL of commercially available hydrogen peroxide with a concentration of 30%; sodium pyrophosphate 6.5-8.5g / L; Sodium oxalate 2.5-4.0g / L; adjust the pH between 7-8; at 50-80°C, stir and oxidize for 1-2 hours, then add neutral grass protease 1398, the amount of which is the input raw material rabbit 5-10% of the weight of wool fibers; adjust the pH between 7.5-8.5, and react at a temperature of 45-55°C for 2-4 hours;...

Abstract

The invention discloses semi-worsted rabbit hair yarn and a processing method thereof, belonging to treatment and processing field of animal fiber, in particular relates to a semi-worsted rabbit hair yarn product which is processed by taking natural rabbit hair as material through the processes of oxidation treatment by hydrogen peroxide and modification treatment by 1398 neutral subtilisin, and a processing method thereof. The processing method includes the following steps: materials pretreatment; oxidation and enzyme treatment; combining the hair and adding oil for health preserving; three times of drawing; roving; spinning; and winding. The invention successfully solves the problem of small friction coefficient, small crimp frequency, low intensity and low cohesion on rabbit hair, which leads to poor spinnability on rabbit hair fiber, and provides a high quality and high yarn count half-worsted rabbit hair yarn product which takes rabbit hair as material, and the processing method thereof. The half-worsted rabbit hair yarn provides high quality material for weaving, knitting, sewing, broidering and tufting industries, and the rabbit hair product is free from hair falling and pilling, thus maintaining the characteristics of rabbit hair.

Description

technical field [0001] The invention relates to a semi-worsted rabbit velvet yarn and a processing method thereof, belonging to the processing and processing of animal fibers, in particular to semi-worsted velvet rabbit velvet yarn products processed by chemical and biochemical treatment using natural rabbit velvet as raw material , and a manufacturing method thereof. Background technique [0002] Rabbit fluff has a diameter of only 5-30 μm, low density, smooth surface, fluffy texture, soft touch, good hygroscopicity, white and flawless, very good warmth retention, comfort, and ornamental value. It is a precious animal fiber. Rabbit hair is used as raw material to process it into yarns of different specifications, providing high-quality raw materials for weaving, weaving, sewing, embroidery, and tufting, and then weaving them into various cloth and fabrics; processing them into clothing, shoes, hats, and bed sheets , curtains, tapestries, etc. It will undoubtedly bring pro...
