Production method of yakwool/bamboo fiber blended yarn

Abstract

The invention relates to a production method of a yakwool / bamboo fiber blended yarn, and the yakwool / bamboo fiber blended yarn is prepared by blending brown yakwool and bamboo fiber, wherein the brown yakwool with the average principal length being 37.4mm, the length discrete degree being 38.3% and the linear density being 4.23dtex is adopted. The method comprises the following steps: (1) preparing yakwool fiber into a yakwool combing sliver by adopting a wool spinning process of raw yakwool pretreatment, worsted carding, first gilling, combing and second gilling; (2) preparing the bamboo fiber into a bamboo fiber sliver by adopting a cotton spinning process of opening picking and cotton carding; (3) blending the yakwool combing sliver and the bamboo fiber sliver through first drawing of cotton spinning, then carrying out third gilling, recombing and regilling of wool spinning, and then carrying out second drawing, roving and spinning of the cotton spinning, thus finally obtaining the yakwool / bamboo fiber blended yarn. According to the production method, the yakwool and the bamboo fiber can be prepared into blended yarns with good quality, and the yarns ensure the yakwool fiber and the bamboo fiber to realize complementary optimization.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a production method of yak cashmere / bamboo fiber blended yarn. Background technique [0002] In the past, the commercial value of yak down fiber was very low, because it was usually used to produce woolen slub yarn and poor quality blended yarn, used for tents and ropes, etc. As the market demand for yak cashmere increases, domestic attention to yak cashmere processing has also increased. However, due to insufficient technology or low production, there are some problems in the processing and sales of yak cashmere in my country. There are various factories that process yak cashmere fiber by carding. Due to the lack of technical equipment and production technology of yak cashmere, the processing of yak cashmere is mainly carded wool spinning. The added value of yak cashmere products is low, and low-grade products are repeatedly processed, which wastes resources to a certa...

Problems solved by technology

In the subsequent spinning process, it is easy to break the end, and the yarn evenness and wool particles are difficult to meet the requirements of lightness and high quality, which greatly reduces the production efficiency of wool spinning mills and other problems.

[0003] Nowadays, the cost of cashmere products is high, but the output is decreasing. At the same time, consumers have higher and higher requirements for the wearing performance and aesthetics of the products, and the pure spinning products of single fiber cannot meet their needs.
