Description
Technical field
The present invention relates to a kind of mulberry skin Rapid atomic absorption techniques, belong to textile technology field.
Background technology
Mulberry fibre is a kind of new type natural fiber developed in recent years, and gloss is good, soft, easy to dye.With
Cotton fiber is compared, and mulberry fibre has more excellent moisture absorption, moisture-inhibiting, crease-resistant, wear-resisting and warmth retention property, is a kind of typical ecology
Fiber.China is silkworm and mulberry silk big country, and mulberry tree cultivated area is wide, and annual winter, the mulberry tree trimming of two season of summer can all generate a large amount of useless
Mulberry branch is abandoned, using Ramulus Mori, primary mulberry fibre textile can be developed, be conducive to the comprehensive utilization of silkworm and mulberry resource, is also spinning
It knits product development and provides innovative space.The quality of mulberry fibre is mainly by mulberry tree breed, growing environment, fiber technology of preparing water
It is flat to influence.A large amount of detection datas show that the mulberry fibre fiber number produced in batches is about the 1/2 of ramie, and intensity is higher than cotton, with ramie
Fiber crops are close, and extension at break is better than cotton, flaxen fiber, and length is only 1/2~2/the 3 of medium staple cotton, and pure spinning is difficult.
The key for producing mulberry fibre is degumming, and Degumming method difference can influence the structural behaviour of mulberry fibre.It is most environmentally friendly
Method be Physical Processing method, but this method efficiency is low, less effective.It is domestic at present generally to use chemical degumming law, but this method pair
Fiber causes a degree of damage, a large amount of chemicals, energy and water is consumed in production, and labor intensity is big,
Pollute environment.
Someone's low-kappa number, degummase carry out degumming to mulberry fibre, but if do not continue with change the prior art
Method assists, then gum level is still up to about 30% in mulberry skin sample.The prior art it is believed that mulberry skin biological enzyme
Degumming industrial production application is not yet ripe, this is because not yet finding the skill of the degummase and culture degummase of best degumming effect
Art is without maturation, and the best degumming tech condition of degummase is also in conceptual phase in addition.
The present invention is intended to provide a kind of mulberry skin Rapid atomic absorption technique, makes full use of bio-fermentation process and biology
Enzymatic treatment can not need mulberry skin fast degumming, whole process chemical method auxiliary, environmental protection, health, great market potential.
Invention content
Technical problems based on background technology, the present invention in view of the shortcomings of the prior art, it is fast to provide a kind of mulberry skin
Fast biological degumming technique makes full use of bio-fermentation process and cellulase treatment, can be to mulberry skin fast degumming, entire mistake
Journey does not need chemical method auxiliary, environmental protection, health, great market potential.
Technical scheme is as follows：
A kind of mulberry skin Rapid atomic absorption technique, its step are as follows：

Living is 2800u/g
Processing parameter is：Bath raio 1: 15, time 100-120min, 45 DEG C of temperature.
To the fermentation generally use ferment at constant temperature of microorganism, the inventors discovered that, in the specific time, take specific
" heat shock " is handled, and can effectively shorten processing time, and gum level can control below 4% after keeping processing.The parameter
Setting is very crucial, and slightly deviation instead can impact effect.
The invention has the beneficial effects that：
The Degumming method natural environmental-protective noresidue of the present invention will not cause environmental pollution, belong to green technology；It makes full use of
Bio-fermentation process and cellulase treatment can be fast to mulberry skin especially to using unique Heat thermostability in fermentation process
Fast degumming, gum level can control below 4% after processing.
Whole process does not need chemical method auxiliary, environmental protection, health, great market potential.
