Fabrication process of blended yarn of wool with rabbit hair

Abstract

The invention discloses a fabrication process of a blended yarn of wool with rabbit hair. The process comprises steps of matching raw materials, opening, cotton carding, drawing, roving, spinning, enzyme treatment, washing, softening treatment, quality control and packaging. According to the fabrication process, the production process is optimized through simplification of the production steps, the production efficiency is improved while the product quality is guaranteed, the increase of market competitiveness is facilitated, and simultaneously, appearances and handle feels of products are better due to the additional steps such as enzyme treatment and softening treatment.

Description

Technical field

[0001] The invention relates to a manufacturing process of yarn, in particular to a manufacturing process of a sheep and rabbit wool blended yarn. Background technique

[0002] Rabbit hair is a precious natural protein fiber. In recent years, it has been widely used in woolen products. It and wool blended fabric with short and smooth wool coats are elegant and smooth, good drape, bright, natural, and warm. Good features, and moderate prices, are favored by consumers. However, due to the limitation of the material of rabbit fur and wool, most of its products have the disadvantages of low strength, poor wear resistance and rough hand feeling. Summary of the invention

[0003] Objective of the invention: The objective of the present invention is to overcome the shortcomings of the prior art and provide a process for producing a sheep and rabbit wool blended yarn with high strength and comfortable hand feeling.

[0004] Technical Solution: In order to solve the above t...
