Abstract
The invention discloses a kind of processing method of worm's ovum shell in fleece fabrics, including prewashing, configuration enzymatic treatment liquid, enzymatic treatment reaction and decatize washing and drying and etc..The processing method of worm's ovum shell passes through the complex enzyme that is made of cutinase, protease and glycoside hydrolase while the scale layer and worm's ovum shell that hydrolyze cashmere fiber in the fleece fabrics, decatize helps to increase the damaged probability of worm's ovum shell, fleece fabrics feel after treatment is more soft, local color depth caused by improving because of worm's ovum shell.
Description
Technical field
The present invention relates to fleece fabrics production technical fields, and in particular to the processing side of worm's ovum shell in a kind of fleece fabrics
Method.
Background technique
Cashmere is special animals wool fiber, be usually attached on animal be with protein food helminth, therefore cashmere
The shell of helminth after death, i.e. worm's ovum shell can be adhered on fiber.Worm's ovum shell and fiber tied up in knots, small part worm's ovum shell and cashmere
It tangles relatively deeply, existing cashmere carding process can not be fully erased, and increasing carding strength inevitably will cause the machine of cashmere
Tool damage.Worm's ovum shell is the combination of chitin and protein, usually has the cryptomere of oblate opening and cavity, cyst wall material
Matter is more loose, has better affinity to dyestuff, since with stronger hydrophilicity, dyestuff is also easy to enter in cavity,
Lead to deposition of dye, thus worm's ovum shell coloring under the conditions of same bath is deep compared with cashmere fiber, and then forms difference in fabric surface
The color spot point of degree, has seriously affected the perception of fabric.
The chitosan finishing cashmere fiber or fleece fabrics for using low molecular weight in the prior art, in cashmere fiber and worm
The low-molecular weight chitoglycan of the protein portion surface uniform adsorption appetite of chorion, utilizes the hydrophilic radical ammonia in chitosan molecule
Base and oxygroup finally make cashmere fiber and the dye-uptake of worm's ovum shell reach unanimity.Above scheme can improve worm's ovum shell part color
It is deeply conscious of aobvious problem, but defect is chitosan treated that cashmere fabric feel is hardened, and influences the fluffy degree and softness of cashmere
Feel.
Therefore, it is necessary to be optimized to worm's ovum shell processing method in the prior art.
Summary of the invention
It is an object of the invention to overcome defect existing in the prior art, a kind of place of worm's ovum shell in fleece fabrics is provided
Reason method is destroyed the cyst wall of worm's ovum shell and the scale layer of cashmere fiber by hydrolysis, improved and uniform dye-uptake.
To achieve the above object, the technical solution of the present invention is as follows: in a kind of fleece fabrics worm's ovum shell processing method, it is special
Sign is, comprising the following steps:
S1: fleece fabrics is placed in deionized water, is heated to 50~60 DEG C, is washed under Ultrasonic Conditions, drying；
S2: main group of configuration enzymatic treatment liquid, enzymatic treatment liquid becomes cutinase, protease and glycoside hydrolase, pH adjusting agent
And water, the pH value of the enzymatic treatment liquid are 7.5~8；
S3: fleece fabrics obtained by S1 is placed in enzymatic treatment liquid, and heat up simultaneously insulation reaction；
S4: taking out fleece fabrics, and band liquid is transferred to individual composition fleece fabrics in decatizing apparatus, washing and drying.
Preferred technical solution is that the cutinase in the enzymatic treatment liquid is fusca cutinase, cutinase in enzymatic treatment liquid
Concentration be 5~10mg/L；The concentration of protease is 0.3~1 mg/L；The concentration of glycoside hydrolase is 1.5~4mg/L.
Preferred technical solution is, pH adjusting agent is selected from disodium hydrogen phosphate-potassium dihydrogen phosphate buffering to, di(2-ethylhexyl)phosphate
Hydrogen potassium-sodium hydroxide buffer to, barbital sodium-hydrochloride buffer to one of.
Preferred technical solution is that the processing time of fleece fabrics is 5~8h in enzymatic treatment liquid, and insulation reaction temperature is 50
~60 DEG C.
Preferred technical solution is that steam temperature is 100~105 DEG C, and steaming time is 2~10min.
Preferred technical solution is that enzymatic treatment liquid further includes soluble magnesium salt, and the concentration of soluble magnesium salt is 0.2~0.5
mg/L。
The advantages and beneficial effects of the present invention are:
The processing method of worm's ovum shell is same by the complex enzyme being made of cutinase, protease and glycoside hydrolase in the fleece fabrics
When hydrolyze cashmere fiber scale layer and worm's ovum shell, decatize facilitate increase worm's ovum shell damaged probability, sheep after treatment
Pile fabric feel is more soft, local color depth caused by improving because of worm's ovum shell.
