Abstract

The invention discloses a novel cashmere sweater washing shrinkage technology. The technology comprises the following steps: 1) pretreatment: placing a cashmere sweater in a pretreatment solution and immersing the cashmere sweater by warm water, performing artificial and uniform overturning until permeation is completed, keeping the material for 30-50 min; wherein a formula of the pretreatment solution comprises citric acid, D-arabinose, collagen, alkaline pectinase with 500,000 u / g, and soft water; 2) fulling treatment: wringing partial moisture of the pre-treated cashmere sweater until the water content is 150-180%, uniformly spraying a composite bacteria liquid, wherein the sprinkling amount accounts for 1-2% of dry weight of the cashmere sweater, controlling the temperature at about 40 DEG C and performing nature fermentation; wherein a formula of the composite bacteria liquid comprises a complex formulation bacteria liquid of acetobacter xylinum and acetobacter xylinoide; and 3) after the fermentation is completed, sprinkling an acetic acid solution, repeatedly beating the cashmere sweater by using a wooden stick for 15 min, washing and dehydrating the material, and drying the material at the temperature of 70 DEG C.

Description

technical field [0001] The invention relates to a novel washing and shrinking process for cashmere sweaters, which belongs to the field of textiles. Background technique [0002] Milling refers to the fact that the fabric is in a wet and hot state, through friction, the fibers are interspersed and entangled with each other, so that the fabric shrinks longitudinally and laterally, the thickness and tightness increase, and a layer of short and dense fluff is formed on the surface, thereby making the fabric more compact. , the appearance of the product is more plump, and the feel is smooth and waxy, and it is full of elasticity; the simple principle of milling: most animal fibers, such as wool (cashmere), rabbit hair, etc., because the surface of the fiber is covered with a layer of scales, after melting and swelling, in Under the action of external force such as rubbing, there are many scale layers in the root part of the hair, so the entanglement is tighter, and the tip part ...
