Technical field
The present invention relates to silk manufacture field, more particularly to a kind of Degumming method of silk.
Background technology
Silk is secreted silk liquid concretionary continuous fiber when matured silkworm cocoons, also referred to as natural silk, is a kind of natural
Fiber.One of earliest animal origin of human use.Silk is most light most soft most thin natural fiber in nature, cancels external force
After can easily restore to the original state, the inner tube of a tyre is not caking, not stuffy, not purse up, homogeneous soft, can forever exempt to turn over use.Silk quilt, uses
First-class silk, with novel fine footpath between fields structure, makes steam free flow.Plus the distinctive ventilative, water vapour permeability of silk itself, make
Silk, which is perceived, more to be slided, and is felt well not warm, warm but not dry.Mulberry silk is mainly made of animal protein, must rich in 18 kinds of human bodies
Must amino acid, can promote Skin Cell vigor, anti-vascular sclerosis, long-time service can anti-skin senescence, have to some skin diseases
Special antipruritic effect, to arthritis, scapulohumeral periarthritis, asthma has certain health-care effect.It is known as " the second skin of human body ", " fibre
The good reputation of dimension queen ".The main component of silk is silk gum and fibroin, and silk gum is wrapped in the appearance of fibroin, and protection is played to fibroin
Effect, in addition also has a small amount of fat, wax and inorganic salts in silk.Usual fibroin accounts for 75%, and silk gum accounts for 25%, but silk gum
You etc. is given in gloss, color, feel, quality and the printing and dyeing that silk can excessively be influenced.Therefore it is previous following process to be carried out to silk fabrics
As will slough silk gum as far as possible, to increase the whiteness of silk, glossiness and dyeability, while make its soft light
It is sliding.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
