Description
Technical field
The present invention relates to fabric-treating agent, desizing enzyme preparation and its preparation side more particularly, to a kind of efficient-decomposition slurry
Method.
Background technology
With the development of production, starch size, PVA and acrylic size are widely used to the starching of yarn.Cloth
On do not move back net leftover slurry and can not only influence the feel of cloth, but also can cause that dyeing is uneven, color spot etc. flaw, because
Can this move back the slurry on cloth and totally be particularly important.
Now, what most of factories used is all that alkali desizing, the desizing of a conduit made of long bamboo oil, oxidant desizing, sour desizing, amylase move back
Slurry.
Alkali desizing：Using caustic soda under the high temperature conditions, occur slurry expanded, reduction and interfibrous adhesive force, make it
It is easy to depart from fiber, washes away and remove by heavy water.
Advantage：1st, cost is low.2nd, contribute to the remover few fibers commensal of cotton seed hulls to remove, mitigate refining burden,
Whiteness, good penetrability.
Shortcoming:1st, desizing rate is not high.2nd, terylene alkali resistance is poor, polyester-cotton fabric desizing will control alkali lye solubility and time.
3rd, to PVA substantially without degradation.4. not environmentally.
A conduit made of long bamboo oil desizing：Washing and peptizaiton using surfactant, in the presence of mechanical force, by the slurry on cloth
Material spreads out, and washes away and removes by heavy water.
Advantage：1st, oil stain on cloth cover etc. can effectively be removed.
Shortcoming：1st, desizing rate is not high.2nd, to slurry without degradation.3 foams and more, need to repeatedly wash could remove,
Oxidant desizing：Play the role of to make the fracture degraded of slurry macromolecular to various slurries, so that easily from fabric
Remove.
Advantage：1st, speed is fast, efficiency high, homogeneous, also certain blanching effect.
Shortcoming：1st, there is oxidation to fiber, causes strength loss.2 not environmentally.
Sour desizing：Dilute sulfuric acid under suitable condition, to PVA without decomposition, but can be such that starch progressively hydrolyzes, and turn
Water-soluble higher product is turned to, is finally washed with water.
Advantage：1st, suitable for containing miscellaneous cotton, can largely remove mineral salt, heavy metal ion, improve whiteness.
Shortcoming：1st, can not degrade PVA.2nd, there is damage to fiber.3 not environmentally.
Starch enzyme desizing：The desizing effect of amylase is that its energy catalytic starch macromolecular chain hydrolyzes, and generates and divide
Some low molecular compounds (dextrin, maltose and glucose) that son amount is smaller, viscosity is relatively low, solubility is higher, then through washing
Remove hydrolysate and reach desizing purpose.
Advantage：1st, only there is degradation to starch, thus do not interfere with the strength of cloth.2nd, because its high efficiency, desizing
Speed is fast.3rd, without any pollution.
Shortcoming：1st, chemical sizwe is acted on without desizing.
But by the retrieval of prior art, not yet find a kind of in all directions can to remove the mixed slurry on cloth
Except desizing auxiliary agent that is clean, will not being polluted to environment again.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of efficient-decomposition slurry
Desizing enzyme preparation and preparation method thereof.
The purpose of the present invention can be achieved through the following technical solutions：A kind of desizing enzyme preparation of efficient-decomposition slurry,
It is characterised in that it includes the component of following parts by weight：
Desizing enzyme：10-50 parts；
PVA digestive enzymes：10-50 parts；
A conduit made of long bamboo oil：1-10 parts；
Deionized water：15-45 parts.
Described desizing enzyme is starch desizing enzyme, and enzyme activity is in 5000-10000U/ml, and optimum temperature is at 50-90 DEG C, most preferably
PH is in 6.0-7.5.
Further, described desizing enzyme is Thermostable α-Amylase, the desizing enzyme CONC that preferably Novozymes Company provides.
Described PVA digestive enzymes are the biology enzyme of PVA slurries of can effectively degrading, its optimal temperature of described PVA digestive enzymes
Degree is 6.0-7.0 in 40-60 DEG C, optimal PH.
Further, described PVA digestive enzymes are the general names of an enzyme system, include 3 species：PVA oxidizing ferment, PVA take off
Hydrogen enzyme, oxidized form PVA hydrolases.
Further, described PVA digestive enzymes are made by the following method：To contain 1,3 butylene glycol as derivant
Broth bouillon is cultivated mixed bacterial, promote its produce film on and endocellular enzyme, then to cell carry out broken wall treatment, broken wall
Centrifuged supernatant after complete, then miillpore filter (aperture is 0.1-0.2 μm) filtering, produces PVA digestive enzymes.
Specifically the preparation of PVA digestive enzymes is that in culture on broth bouillon prepared by mixed bacterial into seed liquor, then
It is inoculated in the broth bouillon of the 1,3-BDO containing 4-6g/l, in 30 DEG C of induction fermentations 3 days.
Wherein, mixed bacterial includes following several commercially available Pseudomonas：Stenotrophomonas sp.；Pseudomonas
sp.；Sphingopyxis sp.；Ochrobactrum sp.；Shinella sp.；Castellaniella sp.；
Microbacterium sp..Above-mentioned several Pseudomonas are commercially available Pseudomonas, and amount ratio is 1.5：1.8：2：1：2.5：1.2：
1.5。
Described broth bouillon is conventional broth bouillon, including peptone：10.0g/L extracted beef powder：3.0g/
L, broth medium sodium chloride：5.0g/L, pH：7.2-7.6.
Described a conduit made of long bamboo oil is nonionic a conduit made of long bamboo oil, is the mixture of nonionic surfactant, and the PH of 10% aqueous solution exists
5.5-7.0。
Further, described a conduit made of long bamboo oil is the mixture of nonionic surfactant, and preferably Shanghai Pin Shan companies provide
A conduit made of long bamboo oil HP6.
The desizing enzyme preparation of above-mentioned efficient-decomposition slurry is made by the following method：
By the control of agitator tank rotating speed in 10~20r/min, then by weight by deionized water 15-45 parts, a conduit made of long bamboo oil 1-10
Part, desizing enzyme 10-50 parts, the order of PVA digestive enzyme 10-50 parts are sequentially added in agitator tank, after all components all add,
Rotating speed is adjusted into 40~50r/min stirrings, 5~10min side again to be made.
The best product of the current desizing effect of in the market i.e. starch desizing enzyme, but because it is to the single-minded of starch size
Property, admittedly have some limitations.As although the desizing auxiliary agents such as caustic soda, a conduit made of long bamboo oil, oxidant, acid also can be to a certain extent by cloth
On slurry get rid of, but itself because desizing not enough thoroughly, have damage, the reason such as not environmentally to cloth, therefore there is also very big
Limitation.Desizing enzyme prepared by the present invention is not only only capable of removing various mixed slurries easily, and to fabric also without any
Damage, its main component is biology enzyme, belongs to protein molecular, Gu to environment also without any pollution.
Compared with prior art, the present invention utilizes degradation property, PVA digestive enzyme pair of the starch desizing enzyme to starch size
The degradation property and a conduit made of long bamboo oil HP6 of PVA slurries are to the synergy of the cleaning performance of slurry, so as to more thoroughly, comprehensively
Ground removes the slurry on cloth, reaches the inaccessiable desizing effect of other desizing auxiliary agents, compared to other auxiliary agent desizing effects more
Good clean, environmental protection and to cloth without any damage.
All-round efficiently desizing enzyme of the invention, its component intersolubility is good, does not interfere with the application effect of each component between each other
Phenomena such as fruit is more not in layering, precipitation, muddiness.While desizing, its component cooperates all-round efficiently desizing enzyme jointly,
Amylase component degradation starch size, PVA digestive enzyme component degradation PVA slurries, along with the cleaning performance of HP6 components, Gu energy
Efficiently reach the inaccessiable desizing effect of conventional desizing auxiliary agent.
