Process for manufacturing blended wool yarns

Abstract

The invention relates to the field of textile technology, in particular to a process for manufacturing blended wool yarns. The process is characterized in that usage boundaries on various traditional spinning devices are broken, and reconfiguration, modification and adjustment are creatively carried out, so that rove staple fibers are spun into separate-count semi-worsted yarns. Yarns are spun by a drafting method, blending and carding of raw wool yarns and doubling drafting of cotton yarns are assimilated, accordingly, colors of spun yarns are uniform, fibers are blended uniformly, surfaces of the yarns are smooth, and the yarns feel fluffy and soft. According to the scheme, the process has the advantages that the process is adaptable to a wide range of raw materials, counts of the yarns can be high or low, the technology is easy to popularize, equipment investment is low, and occupied factory area is small.

Description

Technical field

[0001] The invention relates to the technical field of textiles, in particular to a production process of blended wool yarn. Background technique

[0002] As people's aesthetic level and demand angle of clothing have also changed, people not only pursue its wearability, but also demand that wearability, functionality and decoration are integrated; they are no longer keen on fabrics with too rough styles and begin to pursue details. beauty of. Traditional woolen yarn can no longer meet the current high requirements for woolen fabric styles, and semi-worsted spinning technology has emerged. The biggest difference between semi-worsted spinning and traditional wool spinning and wool spinning technology is that it integrates cotton spinning technology and wool spinning technology to form a new type of multi-component mixing technology. In terms of equipment configuration, cotton spinning technology and wool spinning technology are integrated to form a new spinning pr...

[0012] The present invention will be further described below in conjunction with examples:

[0013] 1. Selection of raw materials: Sheep wool, Australian wool tops, cashmere, etc. are selected according to the needs of the product. Index requirements: fineness: 16.5~2011m, coarse content: ≤0.3%, impurity content: ≤0.5%, short pile: ≤20%, color: white. In order to obtain fibers whose main distribution length tends to be the same, it is necessary to apply fiber drawing technology to draw the crimped fibers repeatedly through multiple rollers with different rotation speeds, and to draw the ultra-long fibers into a straightened state. Short, the short fiber length remains unchanged.

[0014] 2. Pre-spinning pretreatment: When wool is produced on cotton spinning equipment, it is easy to generate static electricity after friction, which seriously affects the spinning process, especially in the process of carding and drawing. Therefore, oil treatment has become a key process for spinnin...
