Abstract
The invention relates to a method for processing wool or animal fibres with low or no felting and a soft feel and special shrink-resistance and strength properties, in which method the wool is treated with a proteolytic enzyme and then at a temperature between room temperature and 140 ℃.
Description
The invention relates to and make wool and animal fiber have low felting or do not play the production technology of felt and the product that obtains therefrom.
For many years, the wool that how can not to obtain felt has become a problem, is head it off, has released many methods, comprises the enzyme processing.This method is as at " weaving is put into practice " 18(1963.3) disclosed by E.P.Friester among the 236-240, his reference be that W.R.Middlebrook and H.Phillips are at " dyeing man " magazine 57(1941) 137-144 page or leaf and ANDavidson and RPreston be at weaving monthly magazine 47(1956) in the 685-707 page or leaf (same be described in belgian patent 536819).Although do not resemble detailed explanation the european patent application 134267, the purpose of handling with enzyme is in order to remove the scale layer of wool, promptly to remove the extexine of fiber fully, thus fiber just lost wool intrinsic natural crimp feature.
The objective of the invention is to process wool and animal fiber, not only keep their natural crimp and intact scale layer, still hang down felting simultaneously or do not play felt.Just can finish this purpose by the enzyme processing, as a comparison, existing treatment technology is shallow and not deep enough.Can in common home laundry machine, wash with the product that this method obtained, and not have adverse consequences.Differentiation is an IWS test method 31 from effective ways of this product that natural wool comes, and is announced by international wool association.Therefore, untreated fiber has just begun felt after three times at the most in described 7A washing, and can stand at least five times and do not play felt with the wool after the enzyme processing according to of the present invention.
Another measure wool fibre whether do not rise felt be according to IWS test method 185 fixed known Cubax test, wherein, the shrinkage of wool was measured by handling with three-dimensional form in a standardized washing facility in one hour.In this test, after the Cubex test continued one hour at least, wool had the shrinkage area less than 10%.This area is interpreted as in the shrinking percentage of length direction and the wrinkle percentage sum on width.Correspondingly in family's washing machine, wash 15-20 time, and do not have contraction or its surface and shape not to have significant change with high speed.
Further, the intensity decreases of the wool that the strength ratio of processing back Woolen yarn is untreated is less than 15%RKM, and percentage elongation descends less than 20%.
Thereby, the invention relates to the processing method of wool or proteinaceous animal fiber, and make it the performance (following character is arranged) that has low felting and do not play felt except that the outward appearance of soft hand feeling, natural wool:
A) Cubax test continued one hour at least or according to five times after-contraction areas of IWS TM317A circulation less than 10%;
B) compare with the untreated wool or the yarn of animal fiber, intensity decreases is less than 15%RKM;
C) percentage elongation descends less than 20%.
The invention is characterized in wool introduced in the bath that protease is arranged to contact, under temperature is the condition of room temperature (20 ℃)～140 ℃, handle subsequently.
Protease is interpreted as any protein cleavage enzyme.Suitable protease is the enzyme that reclaims from bacterium, abstinyl enzyme (esperase) pronase e for example, protease P, subtilysin, thermolysin and the enzyme that from animal-plant material, obtains, for example trypsase, pepsin, pancreatin or bromelain.The mixture of various enzymes also can use, and these enzymes can obtain on market, but the method according to this invention, the preferential protease of selecting is animal and plant enzyme, particularly bromelain.
Add special activating agent, cysteine for example, two sulphur moss sugar alcohols, two sulphur threose or mercaptoethanols can increase the activity of the enzyme that uses.Other additive, the salt of for example known energy stabilized enzyme also can use, as calcium chloride and zinc chloride.Use these salt with the amount that adapts with enzyme.
In long or short a bath, also can use Protease Treatment wool or animal fiber.Handle the mode of preferably selecting dipping, for example, in short the bath by pad, injection, coating or printing wait and carry out.Protease energy and water-bearing media or organic solvent are used together, can also use with the form of slurry or foam.In continuous processing procedure, bath raio is 1: 0.7～1: 10, is preferably 1: 1 to 1: 5, is in a long bath if handle, and then is 1: 10～1: 40.
The temperature preferred values that protease is used is room temperature～60 ℃, and when using conventional buffer, treatment fluid or pH value of slurry are 4～9, are preferably 5-7.
The common use amount of protease is 0.1～2%, and correspondingly the activity of enzyme is 400～1500cDu/mg, with over dry wool re-computation.
After directly handling with enzyme, wool or animal fiber stay to be shelved and/or through heat-treated, and at fabric portions or all under the dry situation, dwelling period can be from being as short as a few hours very much.According to temperature, heat treatment may be carried out several minutes until a few hours, until the wool drying.Saturated vapor, superheated steam, hot blast or high frequency waves (HF) all can be used as heat treatment.When with the saturated vapor decatize, wool or animal fiber stay and shelve 10-30 minute is exactly very favorable.When HF was dry, wool or animal fiber were handled 10 minutes to 1 hour at 100 to 102 ℃ usually.Dwelling period or heat treated condition are to select like this: to obtain the wool of required character, preferably when processing finished, selected enzyme lost activity simultaneously.After processing, the also available known method of enzyme of activity of still having makes it to lose activity.
Subsequently, wool or animal fiber wash, dry and other operation.
According to method of the present invention, employed bath can be used for wool and other proteinaceous animal fiber.Fibrous material can be present in the various procedure of processings, for example, and with the form of loose hair, wool top, rove, yarn, plain cloth, braided fabric, bondedfibre fabric or felt.According to the present invention, can both handle at wool reset condition or that give processing.
In order to obtain the certain effect and/or the optimum efficiency of Protease Treatment, conventional is to carry out the special processing of giving before enzyme is handled, be suitable for giving of wool or animal fiber and handle oxidation processes, for example, use hydrogen peroxide, in the presence of optional stabilizer, with potassium permanganate, Caro ' s acid, chlorine or chloride compound, for example chlorine, hypochlorous acid or organochlorine carrier or ozone; Processing is given in reduction, for example uses hydrogen sulfide, oxo sulfate or sulfide; Alkali treatment, with acid, solvent or enzyme be lipase for example, catalyzing enzyme, oxidizing ferment, peroxidase give to be handled or physical treatment, the ripple of for example using various ways is HF ripple or cold body discharge (Cold dischazge) for example, and these give and handling is known, and uses in partially modified wool.
After giving processing, wool or animal fiber are by rinsing and drying.
Feature according to the selected technology of the present invention is that wool or animal fiber come chlorination by oxidation, uses Protease Treatment then.
Preferably use to have active chlorine and carry out the oxidation chlorination of wool or animal fiber and handle, for example, the chlorine form in water or to contain the clorox form of hydrochloric acid.Give processing with known method, wool or animal fiber stand gentle chloridized, and the amount of active chlorine is 0.1～2%, calculate with the weight of over dry wool or animal fiber.PH during processing is 2-3, and the time is 1-10 second, and temperature is 10～30 ℃.
After giving processing, in order to obtain required enzyme effect, remove for wool or animal fiber and to give finishing agent, and be favourable when making its pH for neutral range.
After chloridized, fibrous material is proceeded to handle to remove residual chlorine, neutralizes subsequently or simultaneously.By the chlorine that uses reductant to remove in fiber or fiber surface exists, for example sodium hydrogensulfite, sodium sulfite etc., with alkali compounds for example alkali carbonate to neutralize also be favourable.
According to selected process conditions, be with or without and give processing, the phosphorus lamella of wool or animal fiber part or slight change or activation are only arranged.Because the result that enzyme is handled, wool that is obtained or animal fiber have a kind of low felting property and in further processing (spin, bleach, dye) and after making fabric use and wash in can not have problems.With the wool after the method processing of the present invention is soft, and more superior is the feel that natural wool is arranged, and when it just is subjected to chloridized in the wool top stage, handles with above-mentioned enzyme then, and the product of gained is just special soft.Adverse influence will not take place in the wool according to the present invention after the processing or the stainability and the dyefastness of animal fiber, comparatively speaking, sizable improvement be arranged.
Following Example will illustrate the present invention, and all percentage all is weight, and all temperature all are degree centigrade.
Example one
Wool tops pads with a kind of liquid bath shampoo [pH is 6.0, contains 0.5% abstinyl enzyme (esperase), and (BacLich, can from NoVo(Denmark) obtains] in the time of 40 ℃, and its amount is a benchmark with weight of over dry wool tops.Pick-up is 50%.
Wool tops behind the dipping was shelved in 102 ℃ superheated steam 15 minutes subsequently.After processing, wool tops is washed and is dry.
The wool of resulting softness has low felting property, and has spinnability, does not almost have waste material.
Example two
Repeat the method for example one, pad and roll do after, wool tops at first during transition all stays, and handles 30 minutes in 100～102 ℃ HF drier then.
