Composite spinning method

Abstract

The invention relates to a composite spinning method. The method comprises the following steps of cotton fiber modification, wherein cotton fibers are added into a reaction solution, and cationic cotton fibers are obtained after treatment; flax fiber pretreatment, wherein after flax fibers are subjected to impurity removal and lengthening treatment, an oiling agent is sprayed; sliver pre-processing, wherein the flax fibers and the cationic cotton fibers are mixed and made into roughly-processed slivers, then the roughly-processed slivers are combined and processed into first slivers through acombing process, and wood fibers are utilized to make second slivers; and drawing and spinning, wherein the first slivers and the second slivers form drawn slivers through a drawing process, then thedrawn slivers are spun into spun yarn, and composite spun yarn is obtained. According to the composite spinning method provided in the invention, the cotton fibers obtained after modification have a high a cationic degree, adsorption of dyestuff by the cotton fibers is greatly improved, the dyeing effect of cotton yarn is improved, the obtained blended yarn has high strength, good settability, high spinnability and excellent moisture absorption and air permeability.

Description

technical field [0001] The invention relates to the field of spinning methods, in particular to a composite spinning method. Background technique [0002] Cotton is one of the most important raw materials in the textile industry. Depending on the spinning process, different qualities of clothing are produced. To make cotton clothes from cotton, firstly, the cotton fiber needs to be processed into cotton yarn by spinning process. However, when cotton yarn is dyed, the adsorption capacity of dyes is limited, and the dyeing effect is not ideal. Hemp yarn is named because it is cool and breathable. [0003] Wood fiber is a type of cellulose fiber extracted from naturally grown wood. Because wood fiber has good air permeability, natural antibacterial, antibacterial, anti-mite, deodorant and anti-ultraviolet functions, the fabric produced has less hairiness, which has attracted the attention of consumers. However, bamboo fiber has the disadvantages of low strength and unsatisf...
