Method.
Background technology
Medical dressing in wound healing process, can substitute impaired skin and play temporarily as the covering of wound
The barrier action of when property, it is to avoid or the infection of control wound, there is provided be conducive to the environment of wound healing.Use suitable part
Antiseptic dressing can fully reduce the infection of wound, while promoting wound healing comprehensively.Medical dressing as wound covering
Thing, in wound healing process, can substitute impaired skin and play temporary barrier action, it is to avoid or control wound infection,
It is provided with the environment beneficial to wound healing.With increasing for aging population and chronic ulcerative wound, the market of medical dressing
Value also becomes more and more important.1962, British Winter proposed " wet wound healing is theoretical ", i.e., wound is in moistening
In the environment of it is faster than being healed under dry environment so that people have breakthrough progress to the understanding of wound healing process.
Silk gum（SilkSericin, SS）It is a kind of globular preteins, accounts for the 20~30% of silk gross weight, by 18 kinds of amino
Acid composition, in these amino acid, polar side chains account for 74.61%, therefore silk gum has good water solubility and water suction
Property.Research simultaneously also demonstrates silk gum to be had good hygroscopicity, biocompatibility, antibiotic property, inoxidizability and promotes thin
Born of the same parents' adhesion and the effect of propagation etc., are the desirable feedstocks for manufacturing biomedical material.
