Abstract
The invention relates to an antifelting finish method of wool knits combining plasma and bio-enzyme, comprising the steps that: wool washing, plasma treatment, protease treatment, water washing, Transglutaminase treatment, water washing, and drying. The invention can lead wool knits to reach machine washable standard (with a felting rate less than 2 percent) while the intensity is ensured (intensity damage is less than 10 percent), and has little damage during the finish process, with safety and environmental protection performance, and is an energy-conservation and clean wool post-treatment technique.
Description
Technical field
The invention belongs to the preventing felting and shrinking of wood fabric field, particularly relate to the anti-felting method for tidying wool knitted fabric that a kind of plasma combines with biology enzyme.
Background technology
Wool product is in when washing processing, and the scale that aligns can cause being subjected to displacement between the fiber through friction, produces the fulling milling phenomenon, thereby it is unclear etc. to cause product dimensional contraction, lines to occur, has a strong impact on outward appearance, feel, easily nurses and take performance.What at present, the anti-felting technology of domestic wool generally adopted is ripe chloridizing and chlorination one resin two-step method (IWS/CSIRO Chlorine Hercosett method).These two kinds of methods are based on chloridized, exist and easily inhale the chlorine yellowing, big to the fiber strength damage, not only making wool fibre be subjected to serious chemical agent corrodes, and exist a large amount of absorbed organic halogenation AOX (Absorbable olganic halagen) can remain in the fiber in the wool treatment process waste water, contaminated environment influences health.In recent years, more and more pay attention to for the pollution problem of the AOX in the wool shrinkproof process both at home and abroad, limit the discharging of AOX one after another with the form of legislation.Under this background, press for and seek new alternative techniques.
Because environmental health problems paid attention to by people day by day, suitable enzyme preparation replacement chloridization process, become preventing felting and shrinking of wood fabric and study focus.But protease is to the hydrolysis of wool CMC globular preteins, make wool cell (comprising scale cell and cortex cell) peel off fibrous body, the uncontrollability that protease is handled wool, make Protease Treatment inhomogeneous, caused the bigger damage of wool fibre, this is the key issue that limits its industrial applications.The difficult problem that protease must be captured research in the anti-felting arrangement of wool is the controllability that guarantees the enzyme arrangement, reduces the damage of fiber, guarantees fabric strength, so just can make protease that the arrangement of wool is had industrialized practical significance.Have report to cooperate TGase (TG enzyme), but chemical method is still used in pre-treatment, as (WO99/60200) such as oxidation or chlorinations with proteolytic enzyme.
Low Temperature Plasma Treating makes wool have certain shrink resistance, but the wool of the anti-felting arrangement of plasma does not reach the machine washable standard, and the limitation of the effective property of plasma treatment.WO96/19611 has reported a kind of plasma pretreatment, and again through the preventing felting and shrinking of wood fabric method of Protease Treatment, but the method also exists than macrolesion the wool brute force.
Summary of the invention
The purpose of this invention is to provide the anti-felting method for tidying wool knitted fabric that a kind of plasma combines with biology enzyme, with what exist in the arrangement of solution protease wool fibre is damaged problems of too, by plasma pretreatment and TG enzyme control renovation technique, reduce the damage of protease to wool fibre inside to fibre damage; Develop the machine washable tricot de laine of anti-felting, low strength damage.
The anti-felting method for tidying wool knitted fabric that plasma of the present invention combines with biology enzyme, be to adopt anhydrous dry plasma pre-treatment, carry out anti-felting with biology enzyme again, technological process is: use the Low Temperature Plasma Treating tricot de laine, bathe or the single bath process processing with protease and TGase two, its concrete steps comprise again:
(1) scouring of wool
Tricot de laine is pressed 1: 20-1: 50 bath raio, in the scouring of wool liquid of 0.5g/L-5g/L, 30 ℃ of-50 ℃ of constant temperature are handled 30-120min.Draws water gently, 80 ℃ of-90 ℃ of oven dry, stand-by;
(2) plasma treatment
At 20-50Pa, handle 1-10min under the 50-150w condition, wherein, gas is the mist of air or oxygen or air and oxygen;
(3) Protease Treatment
The protease mass concentration is 1%-4% (heavy to wool), 30 ℃-55 ℃ of temperature, and time 30min-120min, bath raio 1: 20-1: 50, pH=6-9.
(4) TGase is handled
The TGase mass concentration is 2%-30% (heavy to wool), 30 ℃-55 ℃ of temperature, and time 30min-180min, bath raio 1: 20-1: 50, pH is 6-9;
(5) washing
Handle 10min under 90 ℃ of conditions, behind the enzyme that goes out, cold wash 2-3 time, draws water gently, 80 ℃ of-90 ℃ of oven dry.
Beneficial effect of the present invention:
A kind of plasma of the present invention combines with protease and TGase (TG enzyme) handles tricot de laine, improves the method for its anti-felting property, not only make fabric reach the machine washable standard, and fibre damage is controlled.
Low temperature plasma is destroyed the disulfide bond of wool to the scale layer generation corrasion of wool fibre; On its big molecule, introduced-NH
2,-COOH, water soluble groups such as-OH have increased the hydrophily of wool; These not only help the arrangement of follow-up protease, and corrasion also makes the wet friction coefficient of positive forbidden lamella sheet direction all increase, and the cohesive force that makes wool have good shrink resistance, particularly fiber increases, and the brute force that shows as yarn is improved.
Protease improves the anti-felting property of wool by the catalyzing hydrolysis effect.The TG enzyme is a kind of transferase of catalyzing acyl transfer reaction.Can catalysis wool fibre albumen generation cross-linking reaction, reach the purpose of modification.Particularly, reduce the damage that protease causes fibrous body the anti-felt of wool, when obtaining finishing effect, guarantee fabric strength by of the repair of TG enzyme to the protease damage.
Adopt plasma of the present invention to combine with protease and TGase (TG enzyme) and handle tricot de laine, improve its anti-felting property technology, the felting rate is burst decline below 10% less than 2%.And arrangement process safety and environmental protection of the present invention, be a kind of energy-conservation wool postfinishing process that cleans.
