Spinning process of high-count combed yakwool pure woven yarns

Abstract

The invention discloses a spinning process of high-count combed yakwool pure woven yarns. The spinning process includes the steps of firstly, using a wool combing machine for combing with small spacing, low quantitation and low speed; secondly, using a sliver mixing gill for sliver mixing and carding with small spacing, low quantitation and low speed, controlling moisture regain and performing antistatic treatment; thirdly, using three gills for gilling by processes such as low draft, small spacing, light quantitation, low tension and medium pressure on rubber covered rollers; fourthly, using a cotton roving frame for roving process, using a wool middle rubber covered roll and four rollers for drafting by slide ways; and fifthly, using a cotton spinning frame for spinning process, using a middle rubber covered roll for drafting by a slide way, and using double-roving feeding with small spacing. The spinning process has the advantages that the yarns obtained by the spinning process are high in strength elongation property, and wear resistance, yarn levelness, gloss, card nep rate and the like of the yarns all meet the requirements of using high-grade woven fabrics.

Description

technical field [0001] The invention discloses a spinning process of high-count combed yak cashmere pure spinning machine-woven yarn. Background technique [0002] Yak velvet is collected from yaks living above 3500m above sea level. The unique alpine climate determines that yak velvet has the characteristics of smooth texture, good elasticity, good moisture absorption and moisture release performance, wear resistance and pilling resistance, and high fiber strength. The average fineness of cashmere is 19μm, which is suitable for high-grade worsted clothing fabrics. However, the length of yak wool is short and the difference is large, the curl of the fiber is less and the curl shape is irregular, the specific resistance is high, it is easy to generate static electricity, the scales are ring-shaped, and the thickness is mixed. These index characteristics determine that the spinnability of this fiber is poor. It is very difficult to form yarn. For a long time, the woolen proce...

Problems solved by technology

However, the length of yak wool is short and the difference is large, the curl of the fiber is less and the curl shape is irregular, the specific resistance is high, it is easy to generate static electricity, the scales are ring-shaped, and the thickness is mixed. These index characteristics determine that the spinnability of this fiber is poor. It is very difficult to form yarn. For a long time, the woolen process has been mainly used. The products are mainly coarse-count pure spinning or blended knitting yarns.
