Abstract
The invention involves the preparation method of the compound enzyme tidy up wool fabric which is made through slant culture, fermentation, shocking culture and filtering. Because the enzyme is a kind of biological enzyme preparation, so the wool sweater after being scaled will not contain AOX. As it has good specifity to wool protein, so the wool reduction quantity is just 1-2.5% which basically not influence the intensity and thickness of the wool sweater. Using the compound enzyme to scale under pH=3.0-5.0 acid conditions, the wool sweater will not fade and become yellow.
Description
Technical field
The present invention relates to a kind of preparation method of complex enzyme for wool fabric post-treatment.
Background technology
As everyone knows, the back arrangement of wool fabric as: shrinkproof, soft, mercerising or the like, it is last one processing link during wool fabric is produced.By this link, make wool fabric obtain excellent dress ornament performance, and improve its added value of product.
Wool is a kind of natural protein fibre, and with one deck scale, they are as fish scale or tile is overlapped is covered on the hair shaft on its surface, and scale layer and fibrous body protein layer interrelate with Mierocrystalline cellulose, and also have lipoid layer as thin as a wafer outside scale layer.
Replace chlorination stripping squama with biological enzyme,, be subjected to the favor of numerous investigators and woollen sweater manufacturing enterprise in recent years because it meets the development trend of green back arrangement.But because the present enzyme produced of zymin manufacturing enterprise, main finger protein enzyme, and be not proteolytic enzyme at wool scale, this kind of enzyme is not ideal enough to the effect of wool scale, can not effectively finish the wool keratin of wool scale is peeled off.
Summary of the invention
Purpose of the present invention is just at the deficiencies in the prior art, and provide a kind of wool lipoid layer that can destroy effectively, the preparation method who further decomposes the complex enzyme for wool fabric post-treatment of wool keratin, thereby be implemented under the situation of little effect wool fiber body layer, reach good back finishing effect, for the green arrangement that realizes wool fabric is paved the way.
The preparation method of complex enzyme for wool fabric post-treatment of the present invention: the first step, compound enzyme-producing bacteria add wool powder 0.5% through slant culture in the substratum; Choose bacterial strain occurred frequently, fermentation culture after second step, the cultivation; Substratum be by weight percentage analysis for soybean powder 5%, Semen Maydis powder 1.0%, fish meal 1.0%,, CaCL20.5%, NH4CL 0.5%, Na2HPO4 1.0%, wool powder 0.5%, all the other are water, 30 ℃ of temperature, 200 rev/mins of shaking speed, shaking culture 88 hours; The 3rd step, fermented liquid coarse filtration, filtrate centrifugation, obtain prozyme liquid.
The prozyme that makes according to above method has following characteristics,
1, it is a kind of biological enzyme formulation, can not contain AOX on the woollen sweater behind the stripping squama, meets the development trend of green arrangement;
2, because it is very strong to the specificity of wool keratin matter, the arrangement process makes only 1-2.5% of woolen decrement after the institute, does not influence the intensity and the thickness of woollen sweater substantially;
3, this zymin is shelled squama under the acidic conditions of PH=3.0 ~ 5.0, and woollen sweater can not be faded and yellowing;
4, the biological stripping of this kind squama process can be carried out on existing equipment, is convenient to promote.

Embodiment
Wool embodiment 1: prozyme preparation
Compound enzyme-producing bacteria-→ slant culture, in substratum, add 0.5% wool powder-→ choose after cultivating bacterial strain occurred frequently-→ fermentation culture is a substratum: analysis for soybean powder 5%, Semen Maydis powder 1.0%, fish meal 1.0%,, CaCL20.5%, NH4CL 0.5%, Na2HPO41.0%,, wool powder 0.5%, all the other are water, in 30 ℃ of temperature, 200 rev/mins of shaking speed, shaking culture 88 hours-→ the fermented liquid coarse filtration-→ filtrate separates, at 3000 rev/mins, 10 minutes-→ prozyme liquid obtained.
The prozyme that makes according to above method is used to shell squama and back arrangement, as get the woollen sweater sample-→ the i.e. H of 30% concentration of pre-treatment

30.7%, JFC 3%; bath raio 1: 25; 50 ℃ handle down 35-40 minute-→ add the H2O2 prozyme remove unnecessary H2O2-→ washing-→ dehydration-→ prozyme handles: PH=3.0～4.0, prozyme treatment agent 1～3%; permeate agent 3%; bath raio 1: 20,45～50 ℃ handle 45 minutes-→ enzyme deactivation handles-→ take off liquid-→ washing-→ dehydration-→ oven dry.
Arrangement is used to handle woollen sweater with prozyme after the wool fabric green of the present invention, can not make woollen sweater occur that look becomes, yellowing, does not influence characteristics such as the intensity of woollen sweater and thickness substantially.
