Abstract
The invention discloses a degumming process of natural yellow silk fabrics. The degumming process comprises the following steps: 1) preparing a degumming reagent into a solution of which the concentration is 4-6g/L; 2) placing a natural yellow silk fabric into the solution prepared in the step 1), wherein the bath ratio is 1:100, heating to 80-85 DEG C, and degumming for 30-70 minutes. The degumming process is suitable for a degumming process of the natural yellow silk fabric; with the adoption of the degumming process, proper silk gum dissolve-loss ratio is obtained through controlling the factors such as the degumming time, the degumming temperature and the degumming reagent and the like, colors are retained to a large extent, and the problems that degumming is not uniform and colors are not uniform in the traditional degumming process are overcomesolved, so that not only is the gum-containing rate of the fabric is ensured, but also the natural color value of the fabric is retained to a large extent; and the degumming process of the natural yellow silk fabrics has the advantages of good degumming effect and, environmental protection friendliness,and short time and the like, and can be used for natural yellow silk fabrics of various tissues.
