Abstract
The invention discloses a preparation method of mercerized wool air-layer composite fabric. The preparation method comprises the following steps: chlorination, enzymatic reduction, enzymatic hydrolysis, softening, bonding compounding, digital-printing and the like. According to the chlorine enzymic mercerization technology, a substrate lysine and a catalyst horseradish peroxidase which can rapidly react with wool color-developing lysine residues are added into a treating fluid during the reduction step. By the characteristic of fast enzymatic reaction rate, residual chlorine obtained after chlorination scale-stripping is prevented from undergoing an oxidation reaction with tyrosine residues on the wool surface. By applying the above mercerized wool in production of air-layer fabric, it is guaranteed that yellowing of the mercerized wool layer is small and the fabric obtained after digital printing has bright color. According to the invention, reaction process is not increased, and yellowing protection and free chlorine reduction are combined. The preparation method has simple steps and is convenient to operate.
Description
Technical field
The present invention relates to fabric technical field, the preparation method being specifically related to a kind of mercerized wool air layer composite material.
Background technology
Scale layer is the distinctive structure of wool fiber, and it makes Pilus Caprae seu Ovis have special gloss and felting property, also leads to morphological stability difference and prodding and itching feeling when wearing when woolen dyed difficulty, washing simultaneously. Scale layer is to be passed through cell membrane complexes by cornified flat cell. The mercerising principle of Pilus Caprae seu Ovis is exactly adopt suitable physics, chemical method that the scale of Pilus Caprae seu Ovis is carried out softening degraded, the scale making Pilus Caprae seu Ovis sustains damage, partially or completely divest, thus improving the surface configuration of wool fiber so that it is have the feel as cashmere and gloss. In prior art, the method for physics has resin increasing method, chemical method conventional refinement Subtraction method. It is refinement Subtraction method currently for the method that wool fabric is conventional. Subtraction method includes chloridising, oxidizing process and protease Subtraction method. Chloridising needs to produce substantial amounts of water lotion, and the enzymatic activity of protease method needs strict reaction condition, and the technical scheme of improvement adopts the chlorine enzyme process that chloridising and protease method combine, and the method releases chlorine agent makes consumption few, and the water lotion produced is less. In chlorine enzyme process mercerized wool technique, owing to after chloridized, wool fiber still remains a small amount of chlorine, if not being carried out dechlorination, this residual chlorine may proceed to and the tyrosine residue compound generation slow oxidative reaction in Pilus Caprae seu Ovis, cause Pilus Caprae seu Ovis yellowing, the problem such as strength damage. Above-mentioned Yellowing can make mercerized wool fabric yellowing when Pilus Caprae seu Ovis dye light color. Prior art can avoid above-mentioned phenomenon by selection hydrogen peroxide oxidation method, but damage is also inevitably caused in the surface of wool fiber by hydrogen peroxide oxidation method.
Air layer face fabric is generally composited by surface layer fabric and air layer adjuvant, in order to ensure the novel design of air layer face fabric, prior art adopts digit printing more, but the wool fabric xanthochromia after mercerization finish is big, the purpose bright-coloured in order to reach pattern color, need to increase blanching step, production process increases, complex operation, and bleaching also can damage fiber further and cause fabric decrease in strength, accordingly, it would be desirable to the surface layer fabric mercerising process of air layer face fabric is improved.
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that the preparation method of a kind of mercerization finish post yellowing and the less mercerized wool air layer composite material of strength damage.
For realizing above-mentioned technique effect, the preparation method that the technical scheme is that a kind of mercerized wool air layer composite material, it is characterised in that comprise the steps:
S1: be placed in the aqueous solution that pH value is 3.5��4.5 by the wool fabric after fluffy process, adds chloride stripping squama agent in aqueous solution, reacts 30��40min, then taken out by wool fabric under room temperature;
S2: be impregnated in reduction treatment liquid by the wool fabric with liquid, is warming up to 33��38 DEG C, insulation reaction 5��8h, then heats to 80��90 DEG C of insulation 10��20min;
S3: be placed in the hydrolysis process liquid containing protease and peptidase by S2 gained wool fabric, after 42��50 DEG C of immersion 20��30min, with the cleaning mixture washing that pH value is 5��6 dehydration, repeated washing dehydrating operations 2��3 times;
S4: soft, is placed in S3 gained Pilus Caprae seu Ovis in the aqueous solution containing softening agent and cleans, dry, obtains the wool fabric after mercerization finish;
S5: bonding compound, carries out one side cropping process, and by adhesive by the cropping face of wool fabric and air layer face fabric compound, to wool fabric surface digit printing, obtains mercerized wool air layer composite material S4 gained wool fabric;
Wherein, reduction treatment liquid mainly comprise as TYR, horseradish peroxidase, pH value regulator, reducing agent and water; The pH value of reduction treatment liquid is 7.5��9.5; The pH value of hydrolysis process liquid is 6��8.
Chloride dichlorisocyanurate oxydrolysis makes the disulfide bond in wool scale layer and peptide bond fission, unnecessary free chlorine is scattered in treatment fluid, the TYR residue that wool surfaces generates after chloridized, S2 is increased between stripping squama and reduction treatment, TYR under the catalytic action of horseradish peroxidase with the TYR residue cross-linking reaction on wool fabric surface, form two TYR keys or different two TYR keys, TYR residue is formed protective effect, the chlorine remained after stoping chlorination stripping squama and the TYR residue generation oxidation reaction of wool surfaces, simultaneously, reducing agent and free chlorine react and generate stable chloride ion, 3rd step adopt protease to the peptide chain catalyzing hydrolysis after chloridized, two TYR keys or different two TYR key hydrolysis. utilizing TYR to be cross-linked to form dimer protection wool surfaces and affect the tyrosine residual bond of color, compared with the mercerized wool that chlorine enzyme process of the prior art obtains, xanthochromia is little, and the feel of Pilus Caprae seu Ovis and color are good.
