Abstract
The present invention provides a multi-step chemical method for treating sheep wool to simulate Alpack (alpaca) fibers. 58 to 48 thick branches of sheep wool are treated by five steps of pretreatment, chemical treatment I, biological treatment II, chemical treatment III, chemical treatment IV, etc. by using chemical auxiliary agents which comprise detergent, osmotic reagent, protease, organochlorine and a softening agent to complete the simulation of Alpack (alpaca) fibers on a stock dyeing machine or a top dyeing machine. Therefore, fibers of sheep wool have the advantages of smooth surface, bright and soft luster, soft hand feeling and favorable elasticity and have the surface characteristics of Alpack (alpaca) fibers.
Description
The present invention relates to a kind of textile technology, specifically, is a kind of processing method of clothes raw material.
Alpack (alpaca fibre) fiber is a kind of extraordinary rare animal in highlands such as Peru that is grown in, its wool fibre fineness does not wait from 13～70 microns, good gloss is arranged, flexibility, elasticity and warmth retention property are good, it is the desirable lining of making high-grade clothing, but, need to cause clothing cost very high from national imports such as Peru because of China native country can not produce; The sheep's wool cost is lower; usually the principle of chemical treatment wool is to utilize the effect of organochlorine and common bleeding agent that the scale of wool surface is produced to be partly dissolved; reach the purpose of removing the part scale and pruning the scale corner angle, thereby make wool have softness, smooth, effect that gloss is soft.But this processing method, stripping squama effect is difficult for evenly, and the wool surface of the amino silicon class softener that uses after causing handling is clamminess, very easily adhere to the protein that strips down, give later process as dyeing, spin, weave cotton cloth and the many mass defect of back arrangement initiation, all do not reach the standard of Alpack fiber from performance, outward appearance etc.
The present invention aims to provide a kind of method, the sheep wool fiber that use cost is cheap, through the multistep processes chemical treatment, the apparent Alpack fiber gloss that reaches is become clear, soft, the characteristics that warmth retention property is good can satisfy a large amount of consumption demands of garment material to the Alpack fiber, can save foreign exchange for country again.
The present invention is by following scheme implementation:
1, uses raw material: 58～48 thick sheep's wools.
2, chemicals auxiliary agent: FL detergent, SP-2 bleeding agent, protease, organochlorine (DC) that Henkel KGaA company produces and the softener of forming by TL2800 quaternary ammonium salts organosilicon, urea, acetic acid and emulsifying agent DP.
3, use equipment: stock dyeing machine or top dyeing machine.
4, process route:
(1) preliminary treatment of wool:
Use detergent 2～3%, when 20～40 ℃ of fluid temperatures, add, be warming up to 50～60 ℃, be incubated after 20～30 minutes cooling and washing, discharge water.This process is grease, Impurity removal attached to wool surface.
(2) chemical treatment I
Use bleeding agent 0.5～1%, 20～30 ℃ of addings of fluid temperature are turned round after 5～10 minutes, add organochlorine 4～6%, rerun 5～10 minutes after, add acetic acid 2～4%, regulate pH value between 2～5.5, rerun 30 minutes after, add acetic acid for the second time, the control pH value is between 4～5, turned round 5～10 minutes, and added sodium pyrosulfite 4～6%, fluid temperature is at 40～50 ℃, reacted 15～20 minutes, and discharged water.
In chemical treatment I process, use bleeding agent to destroy the surface tension of water, use organochlorine and wool surface scale to react, it is relatively slicker and more sly to make it the corner.The pH value of use acetic acid controlling liquid is faintly acid makes chemical assistant evenly adhere to, be penetrated into fiber surface, uses the dechlorination of sodium pyrosulfite 4-6% auxiliary agent to handle then.
(3) biological treatment II
Again water filling, temperature rise to 40～55 ℃ and add soda ash 1～3%, and the liquid pH value is controlled between 7～9, turns round 10～15 minutes, adds proteinase-10 .2～0.4%, react to discharge water in 15～20 minutes.
This process is primarily aimed at chemical treatment I process, adds protease and further wool surface is taken place to relax reaction, and the protein that strips down is fully removed and dechlorination.
(4) chemical treatment III
Again water filling, temperature rise to 50 ℃, wash continuously 2～3 times.
(5) chemical treatment IV
Again liquid pH value 5～6 is regulated in water filling, and 20～40 ℃ of fluid temperatures add softener 2～4%, turn round 20～30 minutes, wash continuously 2～3 times, go out machine.
Because the present invention has used multistep processes chemical treatment sheep's wool, selected to be beneficial to environmental protection, the chemical assistant of treatment effect is preferably arranged again, and the heating curve to each link all is controlled at reasonable range simultaneously, makes processed sheep wool fiber more near the characteristic of Alpack fiber.
