Embodiment Construction

[0018] 1 Apocynum extraction, combing process

[0019] Harvest Apocynum stalks, mechanically cut the hemp, remove impurities by machine, degumming with biological enzymes, wash with water, and dry to make dry hemp. The impurity rate of hemp is obtained from combed hemp.

[0020] 1.1 Key points and process of Apocynum extract technology

[0021] Apocynum biological enzyme degumming technology: Apocynum fiber belongs to bast fiber, which contains less glue, pectin has not been lignified, and bast contains less tannin. The bio-enzyme degumming technology is used to form a secondary framework between pectin or pectin and other components of the fiber cell wall. Under the action of enzymes, it is cracked and dissolved to make the cellulose discrete. The optimal process conditions determined for the biological enzyme degumming process are: time 50 min, mass fraction 5%, temperature 90°C, pH value 10-11, mass ratio of pectinase to hemicellulase 4:1.

Abstract

The invention relates to cashmere-Apocynum venetum blended yarns. The number of roving yarns is 28-36Nm, and the raw material proportioning is as follows: 30% of Apocynum venetum and 70% of cashmere, wherein the twist degree is 380/230-435/260 twist/m, the strength is 100/160-90/150g, and the elongation at break is 8%. The production method for the yarns comprises the steps of extracting and fine-combing the Apocynum venetum and then blending the treated Apocynum venetum with the cashmere; the Apocynum venetum extracting process comprises the steps of carrying out Aapocynum venetum peeling, impurity removing, biological enzyme degumming, water washing, drying, oiling, drying on Apocynum venetum stalks, and then obtaining refined dry Apocynum venetum; the Apocynum venetum fine-combing process comprises the following steps of carrying out nourishing, opening and slivering on the refined dry Apocynum venetum, and then obtaining fine-combing apocynum venetum; and the cashmere-Apocynum venetum blending process comprises the steps of carrying out blending oiling, nourishing, combing, spinning, spooling, doubling and double-twisting on the Apocynum venetum and cashmere fiber, to obtain finished products.

Description

technical field [0001] The invention relates to the technical field of cashmere and apocynum fiber blending, in particular to a cashmere and apocynum blended yarn and a production method thereof. Background technique [0002] Apocynum got its name from Lop Nur. Apocynum is distributed in all provinces (autonomous regions) north of Huaihe River, Qinling Mountains and Kunlun Mountains in China. Apocynum is a kind of perennial regenerated wild plant. Among the found wild fiber plants, the quality is the best. It has the softness of cotton, the luster of silk, the refreshingness of hemp, and its unique and excellent hygroscopicity, antibacterial, antiseptic and other properties. Excellent health care function, its fiber is a high-grade raw material for the textile industry; cashmere fiber is an animal protein fiber, the surface is composed of a tight scale layer and a cortical layer, the fiber is thin, soft and smooth to the touch, and has good warmth retention. Soft gold in t...
