Production method of yakwool purely-spun double-color yarns

Abstract

The invention discloses a production method of yakwool purely-spun double-color yarns. Black yakwool and white decolored yakwool fibers obtained through decoloring of black yakwool are separately subjected to a wool spinning technology process, combed wool silvers are obtained, the two types of combed wool silvers are subjected to mixed drawing through drawing of a cotton spinning technology process, and therefore effective mixing of the colored yakwool fibers and the white yakwool fibers which are the same is achieved, and the double-color effect of the mixed silvers is achieved; the mixed silvers are subjected to roving and spinning of the cotton spinning technology process in sequence, the required yakwool purely-spun double-color yarns are obtained, and effective transferring mixing ofthe colored yakwool fibers and the white yakwool fibers is achieved in the drafting and twisting processes of roving and spinning, and therefore production of the yakwool purely-spun double-color yarns with a uniform color effect is achieved.

Description

technical field [0001] The invention relates to the field of novel yarns, in particular to a production method of yak cashmere pure spinning double-color yarn. Background technique [0002] Yak is a rare species that grows on alpine grasslands, mostly at an altitude of 2100-6000m. my country's yaks are mainly distributed in Tibet, Qinghai, Sichuan, Gansu, Xinjiang and other provinces and regions, while foreign yaks are distributed in Mongolia, the Soviet Union, and Central Asia. Chinese yaks can be divided into colored yaks and colorless yaks according to coat color. It is more complex, mainly black, followed by black flower color and brown, mainly determined by the climate and environment of each distribution area. The proportion of black yaks on the Qinghai-Tibet Plateau is relatively large, accounting for 80% of the total survey. At present, the total number of yaks in the world is about 14 million, and there are nearly 13 million yaks in my country, accounting for more t...

Problems solved by technology

However, due to insufficient development of this precious resource, it can only be roughly processed into wool and sold as sweaters. The product has low added value, single structure, and very low profit. This is a waste of resources, so it is better to develop it. Such products not only have practical significance for the development of the western region, but also can prosper the textile market and meet people's demand for new high-grade textiles
