Description
Technical field
The present invention relates to silk processing technology field, and in particular to supplies a kind of silk fast energy-saving method for bleaching.
Background technology
Silk is most light most soft most thin natural fiber in nature, and cancelling can easily restore to the original state after external force, and the inner tube of a tyre is not caking,
Not stuffy, not purse up, homogeneous soft forever can be exempted to turn over and use.Silk quilt, using first-class silk, with novel fine footpath between fields structure,
Make steam free flow.Plus silk distinctive ventilative, water vapour permeability in itself, be perceived silk and more slide, feel well not warm, temperature and
It is not dry.Mulberry silk is mainly made up of animal protein, rich in amino acid necessary to 18 kinds of human bodies, Skin Cell can be promoted to live
Power, anti-vascular sclerosis, long-term use can anti-skin senescence, have special antipruritic effect to some skin diseases, to arthritis, shoulder
Inflammation, asthma has certain health-care effect.Have " skin of human body second ", the good reputation of " fiber queen ".
Silk fiber is bleached after degumming, to remove natural colored thing, otherwise can be produced influence to dyeing, be changed dye
The final tone of color, current silk bleaching is mainly bleached with various chemical classes bleaching agents, the most frequently used for H2O2, concentration for the treatment of
Generally 30%, this concentration for the treatment of can damage silk to a certain extent in bleaching process, the pollution problem that additionally there are.
The content of the invention
It is an object of the invention to provide a kind of silk fast energy-saving method for bleaching.
The technical solution adopted by the present invention is that a kind of silk fast energy-saving method for bleaching, specific process step is as follows：
（1）4-5g sucrose, 1-2g sodium glutamates, 2-3g urea, 1-2g sodium iodides is added into every L potatoes Normal juice to be well mixed,
As activating solution, cultivated into activating solution by the weight of 1-1.8 ‰ than inoculation geotrichum candidum at 33-35 DEG C to activating solution miospore
Number is 106More than CFU/ml；
（2）By activating solution even application on silk, handled 2-3 hours at 26-28 DEG C；
（3）Silk after processing is sent into 3%H2O2Immersion treatment 5-7 minutes in solution, silk is pulled out, in feeding water washing tank
Centrifugation washing, sets washing pressure inside the tank as 8-12MPa, water lotion presses 1000 by deionized water, potassium sorbate:1-1.5 weight
Amount ratio is mixed to get, and centrifugation rate is 85-90r/min during centrifugation washing；
（4）After silk after processing is drained away the water, dried in feeding drying chamber.
It is preferred that, 4.2g sucrose, 2g sodium glutamates, 2.5g urea, the mixing of 1g sodium iodides are added into every L potatoes Normal juice
It is even, it is used as activating solution；
It is preferred that, into activating solution by 1.5 ‰ weight than inoculation geotrichum candidum；
It is preferred that, it is inoculated with into activating solution after geotrichum candidum, it is 10 that viable count is cultivated into activating solution at 33-35 DEG C7CFU/ml；
It is preferred that, during centrifugation washing, centrifugation washing clockwise；
It is preferred that, during centrifugation washing, centrifugation washing counterclockwise；
Beneficial effect of the present invention is,
The present invention to silk before being bleached, and the geotrichum candidum activating solution that activation is obtained is sprayed on silk, acts on fiber
Surface portion, improves the permeability of fibre structure, so that the consumption and concentration of chemical bleaching agent are saved, under low concentration processing
Also the higher silk of whitness index can be obtained, bleaching cost is not only saved, contaminative of the bleaching to environment is also reduced；
During centrifugation washing, deionized water, potassium sorbate are pressed 1000:1-1.5 weight ratio is mixed to get water lotion, it is possible to increase
The degree of polymerization between silk fiber, has certain help to improving silk fracture load.
