Abstract

A treatment to make cotton fiber more hygroscopic .The process includes enzyme treatment on cotton fiber to enhance its smoothness and strength, dyeing on fiber, softening agent treatment to make it more hygroscopic and to lower its specific resistance. Cotton made by this process shows high quality such as softy, smoothy and hygroscopic. It is also time saving and energy saving.

Description

Make cotton bulk fibre have the method for sorting of high moisture absorbing and sweat releasing performance
Technical field
The present invention is a kind of method for sorting of high-hygroscopic and perspire fibre with cotton-dispersion, refers specifically to the functional treatment method of cotton fiber.
Background technology
Along with the improvement of people life, the raising of the level of consumption for the characteristic that lining not only will keep crease-resistant, non-ironing, easily wash, does soon, also will have gorgeous and slim and graceful outward appearance and performance such as comfortable and easy to wear.But there is primary cell wall on the natural cotton fiber top layer, and the cotton wax in this primary cell wall is cotton hydrophobic root; Except cotton wax, insoluble other salt that belongs to pectic substance has also encouraged the hydrophobicity without the cotton fiber of kiering.And the cotton fiber after the traditional dyeing and finishing processing of process also greatly reduces cotton hygroscopicity because of containing more hydrophobicity finish, and therefore common cotton look spinning hydrophily is generally all relatively poor.For these reasons, the dyeing and finishing worker is just setting about studying the hydrophily of cotton fiber and is handling, generally adopt now that cotton fiber is carried out the cotton spinnability with hydrophilic effect that obtains after the kiering is very poor, feel is coarse, the damage that fiber is subjected to is also bigger.
Summary of the invention
The objective of the invention is a kind of environment-friendly type preparation method, thereby improved the spinnability of cotton bulk fibre and the hydrophily of look textile product for the hydrophilic cotton spinnability difference that overcomes the preparation of the relatively poor and traditional handicraft of traditional cotton look textile product hydrophily.
A kind of method for sorting that makes cotton bulk fibre have high moisture absorbing and sweat releasing performance, its characteristics are bulk cotton fibres is handled through a certain amount of biology enzyme.Dye again after after biology enzyme is handled, using the caustic soda high temperature deactivation.Described biology enzyme comprises refining enzyme and cellulase.
Described refining enzyme is a kind of textile auxiliary, can use the commercially available prod, such as the wide GJB scouring enzyme of strong Fine Chemical Works in the KOSONMEMC of Gaosheng textile auxiliary and Guangzhou, be a kind of environment-friendly type compound biological enzyme cotton fiber refining finishing agent, also have the letter 301L of scouring enzyme Novi.
Cellulase is catalyzing hydrolysis cellulose, the general name that generates the smooth enzyme of grape, and the enzyme of being made up of the multicomponent enzyme is.That sells on the market believes cellulase L as Novi, its commodity Cellusoft L Chinese by name soft and slender enzyme L by name, be a kind of liquid fiber element that in water, ferments and form by the germ of nonpathogenic bacteria, also have Cellusoft (the plain enzyme of multicomponent fibre), Cellusoft PLUS (the plain enzyme of gene modification multicomponent fibre), Cellusoft ultra (gene modified cellulose enzyme), Cellusoft AP (the plain enzyme of gene modification multicomponent fibre).
The method for sorting of above-mentioned high-hygroscopic and perspire fibre with cotton-dispersion, its characteristics are that the technology that described biology enzyme is handled is: with cellulase, the mixed solution of scouring enzyme and bleeding agent is poured dye vat into, refining enzyme wherein, cellulase, the mass percent concentration of bleeding agent is respectively: 0.5~5%, 0.5~5% and 1~5%, under the water hardness condition with higher, can add 1~5% chelated dispersants such as WA, CT powder etc., transfer pH to 4.5~6.5 with weak acid such as HAC, bulk cotton fibres is joined in the above-mentioned mixed solution, the bath raio of described mixed solution and bulk cotton fibres is 8~30, in 80~100 ℃ in 50~70 ℃ of caustic soda that add 5~30 grams per liters after handling 10~40 minutes, flood after 10~70 minutes, with acetic acid neutralization and be washed to neutrality.Adopt cellulase refining, biology enzyme polished finish, effectively removed impurity such as cotton wax, not only feel is fluffy smooth, and has improved hydrophily, does not reduce the spinnability of fiber simultaneously again.
Adopt after the above-mentioned bioenzyme pretreatment technology, also to carry out post processing, mainly be to adopt softener to handle, described softener is a kind of hydrophily consistent lubricant or cellulose moisture control agent such as vapour crust ULTRAPHIL DCW, and the hydrophily consistent lubricant that uses is 3098 of the two rainbows of auxiliary agent such as Shenzhen of vapour crust.Concrete process is: with the mixed solution of hydrophily consistent lubricant or cellulose moisture control agent and bleeding agent, with HAC adjust pH to 5~7, bulk cotton fibres is joined in the above-mentioned mixed solution, the bath raio of described mixed solution and bulk cotton fibres is 8~30, handle after 10~50 minutes directly dehydration, oven dry for 40~70 ℃.Wherein the mass percent concentration of hydrophily consistent lubricant or cellulose moisture control agent is 2%~10%, and the mass percent concentration of bleeding agent is 1%~5%.
Above-mentioned bleeding agent can be a kind of common anion surfactant, plays the effect of diffusion and uniformly penetrating.As wetting agent jfc (that is: isobutyl group phenoxy group polyoxyethylene ethanol).
Above-mentioned aftertreatment technology can be handled with bathing in fixation stage and color-fixing agent, also can handle separately after fixation.
The cotton fibrid such as cotton, sliver and comber web, natural color cotton etc. that bulk cotton fibres described in the present invention is true qualities, bleach, brighten, dye.
The preparation method of the high moisture absorbable and breathable finishing of cotton bulk fibre of the present invention has following characteristics:
1, can improve the fiber fluffy degree with the enzyme refining in the pre-treatment, and traditional technology feel is very hard and coarse;
2, improve the fineness of fiber outward appearance with biology enzyme polishing back, guarantee the brute force of fiber;
3, has good spinnability;
4, shorter than traditional process time, energy consumption is lower, and product is environmental protection more;
5, behind the employing biopolishing enzyme, its fiber short down obviously descends, and the cloth pilling resistance that is made into is significantly improved;
6, guarantee the effect of high moisture absorption in the post processing with hydrophilic softener or cellulose moisture control agent, the regain of control look cotton reduces than resistance, further improves spinnability.
7, adopt the vertical wicking height of the lining 30min after cotton bulk fibre of the present invention is processed through weaving to reach more than the 15cm.
The specific embodiment
Example one (raw white)
Select 100 kilograms of bulk cotton fibres for use, put into the solution that bath raio is 1:8 at normal temperatures, the letter 301L 1% of scouring enzyme Novi, cellulase L 1%, bleeding agent 1% usefulness HAC transfers PH to 4.8, handle the caustic soda that add 8 grams per liters after 20 minutes for 55 ℃ and be warming up to 90 ℃, flood after 30 minutes, neutralize and be washed to neutrality with acetic acid.Post processing adds hydrophily consistent lubricant 3,098 5%, and penetrating agent JFC is 3%, transfers PH to 5.5 with HAC, and bath raio 1:8,60 ℃ of dippings are after 30 minutes, and directly dehydration is dried.The fluffy softness of cotton feel that use this method is produced, smooth, water imbibition is splendid, adopts the vertical wicking height of its lining 30min that knits system to surpass 15cm.
