Abstract
The present invention develops a chemical modification technology for goat wool and thick wool fiber of special animals and a modifier. The technology comprises wool fiber loosening, water soaking, modification, water washing, acid washing for reduction, water washing and drying by centrifugation and baking. The modifier is prepared from alkali metal hydroxide, oxidizer, a curing agent, a fiber protecting agent, a promoter and water. After being processed by the technology and the modifier, goat wool and various kinds of thick wool have the advantages of increased flexibility, low fineness, fine curling and glossiness, and the goat wool and the thick wool can be used for weaving carpets and blankets.
Description
Field under the present invention: textile material processing
Goats hair and special animals coarse wool fiber such as camel hair, yak hair etc. have all that fiber is straight, smooth surface, the scale subtended angle is little, fiber is thick, long, the fiber rigidity more by force, does not almost have the low character of curling cohesive force, be difficult to use in wool textile industry, past attempts is used for system hair rope, felt more or serves as aspect such as filler.
China has at least 5-8 ten thousand tons wool and a large amount of special animals coarse wool dimensions to fail to obtain processing and utilization well every year, the a large amount of outer hair of annual simultaneously import again is used for weaving of carpet, woollen blanket, and the present invention promptly develops the chemical modifying process of goats hair and animal coarse wool fiber according to this present situation.Through goats hair after the chemical modifying process processing of the present invention's development and animal coarse wool fiber is that flexibility increases, fineness reduces, produce well curl, cohesive force makes moderate progress between fiber, glossiness is good, can be used for weaving of carpet and woollen blanket, thereby the large textile raw material of China is developed, can be country and save a large amount of foreign exchanges.
The objective of the invention is to: according to China's present woollen mill existing equipment and take into full account and use homemade industrial chemicals, the spy is developed into the chemical modifying process of novel goats hair and coarse wool fiber.This invented technology is simple, cost is low, practicality is very strong.
Task of the present invention is: utilize wool fibre that modified technique draws to bounce back in pickling process and drying process, thereby generation is curled and thick class wool fibre better spinnability is given in typing.Simultaneously, the surperficial scale of keratin protein wool fibre is expanded, the part scale is divested, and the subtended angle of residue scale increases, and the concavo-convex degree of fiber surface increases, the cohesive force enhancing.
The present invention develops is used for goats hair and special its main feature of animal coarse wool fibre chemistry modified technique is at first wool fibre shredding of modified technique, immersion, add the modifier prepare then and carry out sex change 10-30 minutes, wash, use organic acid (acetic acid, formic acid) pickling reduction 15-50 minutes again, wash back drying, drying, drying temperature under the air blast state 75-80 ℃ again, fiber can stop when containing tide and reaching 15-20%, and criteria thus the drying time is 15-25 minutes.Preparation modifier; adopt the aqueous solution of preparation alkali metal hydroxide (NaOH, potassium hydroxide) earlier; respectively the aqueous solution of oxidant (hydrogen peroxide, calper calcium peroxide) and vulcanizing agent (vulcanized sodium, potassium sulfide) is mixed stirring with the alkali hydroxide soln for preparing then; fiber protective agent (phosphate, polyphosphate) is added in the mixed liquor that stirs; add gauge water again; normal temperature stirs down and makes the solution clarification, adds fibre modification promoter before using.(alkyl phenol polyoxy alkene ether, higher alcohols polyoxy alkene ether JFC).The recipe ratio of modifier each component is (percentage by weight)
Hydroxide 0.2%-0.9%
Oxidant 0.25%-1.0%
Vulcanizing agent 0.15%-0.5%
Fiber protective agent 0.025%-0.25%
Promoter 0.001%-0.01%
Water 99.3%-97.2%
Embodiment:
With 50 kilograms of goats hairs that give after first shredding, the immersion, immerse molten ratio and be in 1: 20 the aqueous solution of modifier, stir, leave standstill under the normal temperature (20-25 ℃) and soaked 17-25 minutes, emit solution, after clear water rinsing only, embathed 15-30 minutes in the acetum with hair immersion 1%, emit acid solution, water is clean with the hair rinsing, the modification goats hair that drying can obtain to have good spinnability under 75 ℃ of air blast situations.
Claims (3)
1, a kind of chemical modifying process that is used for goats hair and special animals coarse wool fiber is characterized in that modified technique is:
At first wool fibre shredding immersion, add the modifier for preparing then and carry out sex change 10-30 minutes, wash, use organic acid (acetic acid, formic acid) pickling reduction 15-50 minutes again, after washing again, dry, drying, drying temperature under the air blast state 75-80 ℃, fiber can stop when containing tide and reaching 15-20%, and criteria thus the drying time is 15-25 minutes.
2; goats hair according to claim 1 and special animals coarse wool fibre chemistry modified technique; it is characterized in that preparing modifier; adopt preparation alkali metal hydroxide (NaOH earlier; potassium hydroxide) the aqueous solution; then respectively with oxidant 1 hydrogen peroxide; over hydrogenation calcium) and vulcanizing agent (vulcanized sodium; potassium sulfide) the aqueous solution mixes stirring with the alkali metal hydroxide aqueous solution for preparing; with fiber protective agent (phosphate; polyphosphate) adds in the mixed liquor that stirs; add gauge water again; normal temperature stirs down and makes the solution clarification, and (the alkyl phenol polyoxy is alkene ether to add fibre modification promoter before using; the higher alcohols polyoxy is alkene ether .JFC)
3, the chemical modifying process of goats hair according to claim 2 and special animals coarse wool fiber is characterized in that the recipe ratio of the each component of modifier is (percentage by weight)
Hydroxide 0.2%-0.9%
Oxidant 0.25%-1.0%
Vulcanizing agent 0.15%-0.6%
Fiber protective agent 0.025%-0.25%
Promoter 0.001%-0.01
Water 99.3%-97.2%
