Description
Technical field
The present invention relates to the technical field of silk production more particularly to a kind of efficient Degumming methods of silk.
Background technology
Silk gum wraps up and penetrates into two fibroins and just constitutes a silk, and silk gum belongs to albumen, but the two structure with fibroin
There is difference with Amino Acid Composition.Fibroin albumen is main component part in silk, accounts for about the 70%-73% of quality, silk gum is about
Account for 23%-25%, also 5% or so other media.Silk gum is water-soluble preferable globular protein, and silk is dissolved in hot water
Middle degumming is concise, this characteristic of silk gum is exactly utilized.Since the amino acid of silk gum and fibroin forms difference, fibroin is fibre
Albumen, silk gum are globulin, so the silk overall length that silkworm is spat is up to 800-1200 meters.True protein of the fibroin containing about 97%, by
18 kinds of amino acid compositions, wherein 8 kinds of predominant amount highest is amino acid necessary to human body.Silk, which is integrated with, belongs to porous fibre
Dimension, the structure of particulate under the microscope（MCM-41 mesopore molecular sieves）Similar activity carbon molecular sieve（NK30AP) structure, silk peptide
Conformation：Antiparallel-foldable structure.
The concise essence of silk fabric is exactly to be removed using technique appropriate and equipment using these differences of fibroin and silk gum
It removes silk gum and retains fibroin, to achieve the purpose that degumming.
The Degumming method of silk is divided into two class of microbial degumming and chemical Degumming at present, and chemical Degumming is again according to the change of use
It learns drug difference and has alkali degumming, the degumming of soap alkali, sour degumming.But at present these method generally existing degumming efficiency is low asks
Topic, cannot carry out degumming well, to largely affect the application of silk, while in order to pursue higher degumming effect
Rate often takes the means that different degumming modes are combined, although can improve degumming rate, result to a certain extent in this way
It is often unsatisfactory, while problem with high costs is also resulted in, therefore, it is necessary to propose a kind of efficient degumming side of silk
Method.
Invention content

Under the conditions of the pH9.5-10 of modulation mixing liquid pool, and keep mixing liquid pool temperature at 95-98 DEG C, immersion treatment 50-60min；
（3）Step（2）Silk after immersion treatment is finally putting into the liquid of brightening agent VBL0.1-0.2g/L, anhydrous sodium sulphate 2-3g/L
Chi Zhong, liquid pool temperature handle 20-30min at 56-60 DEG C；
（4）Step（3）Treated, and silk is immersed in again in deionization aqueous, and the temperature of deionization aqueous is heated to
70-75 DEG C, stir process 70-80min；
（5）Step（4）Treated, and silk is down to 25-30 DEG C in the temperature of deionization aqueous, and is carried out on centrifugal dehydrator
Dehydration, dehydration 5-8min, you can obtain the silk after degumming.
Advantageous effect is：The treatment process steps of the present invention are simple, and processing input cost is relatively low, and can increase silk
Degumming rate, selected substance are free of pollution sources, are conducive to promote the use of.
