Abstract
|
|
|
The sericin fixation of raw silk by formalin and glutaraldehyde mixed solutions was done and the effect of sericin fixtion by various conditions on degumming ratio, whiteness and physical properties was investigated and discussed.
The obtained results were summarized as follows ;
The sericin fixation by 1% formalin solution and upward, regardless the concentration of glutaraldehyde solution, improved the whiteness of raw silk to 96% level of non fixed raw silk. The decrease of whiteness by degumming was prevented effectively by treatment of formalin and glutaraldehyde mixed solutions. The complete sericin fixation was obtained by the treatment of mixed solution including above 0.5% formalin solution. The proper treatment of sericin fixation can make increase the values of tenacity and elongation of silk.
