Novel manufacturing method for linen-cotton blended yarn

Abstract

The invention relates to a novel manufacturing method for a linen-cotton blended yarn. The novel manufacturing method comprises raw material pretreatment, treatment before blending and treatment after bending. The raw material pretreatment comprises firstly softening a fibrilia, blowing, carding and packaging the fibrilia, secondly softening the fibrilia, and blowing, carding and packaging a cotton fiber. The treatment before blending comprises arranging and mixing packages of the fibrilia and the cotton fiber which have been pretreated respectively on a disc cotton picking according to a set weight ratio, and blowing, carding and drawing in order using a blowing machine, a carding machine and a drawing frame to obtain linen-cotton fiber strips. The treatment after bending comprises roving, spinning, winding and packing the linen-cotton fiber strips. According to the novel manufacturing method for the linen-cotton blended yarn, the fibrilia are softened twice, the spinnability of the fibrilia is improved, the work efficiency is raised, the cost of production is reduced, at the same time, the quality of the yarn is raised, the minimal brute force and the average brute force of the yarn can be increased, the uniformity of the yarn is improved, and the hairiness value, nep and other indexes are distinctly improved.

Description

technical field [0001] The invention relates to the textile field, in particular to a production process of a novel hemp-cotton blended yarn. Background technique [0002] Hemp fiber is a natural plant with good hygroscopicity, comfort, drape and stiffness and good dyeability. In addition, it can be blended with cotton, wool, hemp, nitrile, polyester, etc. According to people's different grade requirements, it can be spun into fabrics. All kinds of new textile products meet people's pursuit of "clear, cool and new" fashion requirements for environmental protection and health care. In the production of linen-cotton blended yarn, the routinely used technological process is wrapping. In each process of spinning, due to the thick, short, hard, no crimp, and poor cohesion of the linen fiber, the processing count of the traditional process is low. Generally below 20, it is difficult to form a net into a sliver alone, and it is prone to problems such as low production efficiency, ...

Problems solved by technology

In the production of linen-cotton blended yarn, the routinely used technological process is wrapping. In each process of spinning, due to the thick, short, hard, no crimp, and poor cohesion of the linen fiber, the processing count of the traditional process is low. Generally below 20, it is difficult to form a net into a sliver alone, and it is prone to problems such as low production efficiency, many grains and neps, and poor quality of finished yarns. It is also easy to have low efficiency and many defects in the weaving process, resulting in defective fabrics Product rate
