Abstract
The invention belongs to the technical field of wool fabric industry, and particularly relates to a yak hair softening method. The proposed technology method comprises the following steps: acidification, reduction and smoothing sequentially. According to the characteristics of yak hair fiber, the curling of the yak hairs can be increased to the maximum extent by adopting an oxidation-reduction method, fibers are softened, fiber damage can be reduced, the fibers are smoother and softer, machine spinning is benefited, the spinning efficiency and quality and yarn formation rate are greatly improved, and the application range of the yak hair can be widened.
Description
One, affiliated field:
The invention belongs to Wool Textile Industry technical field, particularly a kind of softening method of yak hair.
Two, background technology:
Yak is the peculiar ox kind of extremely frigid zones, phytophage ruminant domestic animal.Mainly originate in Chinese Qinghai-Tibet height above sea level more than 3000 meters area, yak hair have marrow hair few, and medula is also little, intensity and elongation good.Yak hair diameter is greater than 25 microns, and length can more than 20 centimetres, and profile is straight, smooth surface, and what have has continuous medula, and strong and unyielding and glossy, felting property is low.Yak hair fiber major part is made up of scale layer and cortical layer, only containing few medullary substance layer, brute force is higher, but is close to hair shaft, smoother, cohesive force extreme difference because of its scale, and fiber is thick, long, curling less, stiffening, upright and outspoken, bring extreme difficulties to spinning.
Three, summary of the invention
For the shortcoming that yak hair spinning is difficult, the invention provides a kind of softening method of yak hair, the process that the present invention intends taking is: acidification → reduction treatment → submissive process,
The process conditions of acidification are: in water, add formic acid or acetic acid, adjust PH=5 ~ 6, obtained acidifying solution, and at ambient temperature, yak hair in mass ratio: acidifying solution is 1:6 ~ 12, soaks yak hair 30 ~ 100 minutes; The process conditions of reduction treatment are: dewatered by the yak hair of acidification, sodium sulfite is added in water, adjust PH=7.5 ~ 8, add 2 ~ 4% hydroxy methylimidazole quinolines of yak hair quality again, obtained reducing solution, under 70 ~ 90 DEG C of conditions, yak hair in mass ratio: reducing solution 1:6 ~ 12, soaks the yak hair after dehydration 20 ~ 50 minutes; The process conditions of submissive process are: dewatered by the yak hair of reduction treatment, in water, add the 2-4% modified silicon oil of yak hair quality, obtained submissive liquid, under 30 ~ 50 DEG C of conditions, yak hair in mass ratio: submissive liquid 1:3 ~ 6, soaks the yak hair after dehydration 10 ~ 20 minutes; The present invention is the feature according to yak hair fiber, adopt oxidation-reduction method, increase the curling of yak hair to greatest extent, make fiber softening, add hydroxy methylimidazole quinoline, can fibre damage be reduced, make fiber submissiveer softening, advantageously spin in upper machine, the efficiency of spinning, quality, resultant yarn rate improves greatly, has widened the range of application of yak hair fiber.
Four, detailed description of the invention:
Embodiment 1: a kind of softening method of yak hair, take dry yak hair 100Kg, water 600 Kg, formic acid is added in water, adjust PH=5, obtained acidifying solution, at ambient temperature, soaks yak hair after 30 minutes and dewaters in acidifying solution, sodium sulfite is added again in 1200 Kg water, adjust PH=8, then add the hydroxy methylimidazole quinoline of 2 Kg, obtained reducing solution, under 70 DEG C of conditions, soaked by yak hair after acidification after 50 minutes and dewater, in 300 Kg water, finally adding 2 Kg modified silicon oils, (chemical name: dimethyl silicone polymer, molecular formula is: (CH
