Abstract

The invention discloses a production process of a cashmere and marine cell blending yarn. The production process comprises the steps of A. loosening; B. pretreating; C. carrying out cashmere dyeing; D. carrying out marine cell fiber dyeing; E. carrying out secondary dyeing; F. combining; G, carrying out gilling; H. combing; I. spinning; and J. drawing. As the production process is adopted, the color aberration of cashmere and marine cell fiber blending product is reduced; the color fastness and the blending uniformity are improved.

Description

technical field [0001] The invention relates to the field of dyeing and spinning, in particular to a production process of cashmere marine cell blended yarn. Background technique [0002] Cashmere is a thin layer of fine velvet that grows on the outer skin of goats and covers the roots of goats' coarse hair. It grows out when it is cold in winter to resist the wind and cold. It falls off after the warming of spring and naturally adapts to the climate. It is a rare special animal fiber. The reason why cashmere is very precious is not only due to the scarcity of output (accounting for only 0.2% of the world's total animal fiber production), but more importantly, its excellent quality and characteristics. "Fiber Queen", "Soft Gold". [0003] Pure cashmere products are soft, comfortable, and warm-keeping, but they have high shrinkage rate, poor air permeability and easy to produce peculiar smell. They are prone to static electricity after wearing in winter. At the same time, pu...
