Abstract
The invention discloses a domestic animal hair, down and domestic polylactic acid fiber blended yarn roving production process, which sequentially comprises the steps of raw material selection, a wool blending process, a carding process, a spinning process and a spooling process; selecting domestic wool fibers and domestic polylactic acid short fibers; the domestic wool fibers at least comprise one of domestic wool, cashmere fibers, domestic rabbit hair fibers or domestic yak hair and yak wool fibers. The synthetic polylactic acid fiber is mixed with domestic wool, rabbit hair and yak hair by utilizing the good spinnability of the synthetic polylactic acid fiber, so that the utilization rate of the domestic wool, rabbit hair and yak hair is improved, and the wool-containing blended yarn meeting the requirements can be prepared. The usage amount of domestic wool, rabbit hair and yak hair can be increased, the income of herdsmen is increased, and the dependence on imported Australian wool is reduced. By adopting a proper production process, the prepared roving completely reaches the FZ/T71006-2009 cashmere knitting yarn standard, and the problem of domestic animal wool roving is solved.
Description
Technical Field
The invention relates to the technical field of blended yarn production processes, in particular to a blended yarn of domestic wool fibers and polylactic acid fibers and a roving production process.
Background
The Chinese wool spinning industry occupies a very important position in the global wool spinning industry: in the world 35% of wool is processed in china and 18% of wool products are consumed in china. The productivity of the Chinese wool spinning industry is the first world, China is the largest wool entry country, production and processing country and wool product consumption country in the world, and plays a very important role in the global wool spinning industry.
