Abstract

The invention discloses a silk fabric dyeing method which includes the steps: 1) sequentially adding titanium dioxide, beta-aminopropionic acid, N-methyl pyrrolidone, sodium silicate and plant dyestuff into a dye vat, sequentially adding raw materials into deionized water, uniformly stirring the raw materials and heating the raw materials to reach 55 DEG C; 2) sequentially adding chitosan, secondary alkane sulphonate sodium, urea and dibutyl phthalate, continuing stirring until sufficiently and uniformly mixing the raw materials, and heating the raw materials to reach 65 DEG C; 3) soaking a fabric in the dye vat for 25 minutes; 4) drying the soaked fabric at the temperature of 80 DEG C; 5) soaking the dried fabric in clear water and rinsing the fabric for 25 minutes; 6) taking out the rinsed fabric and naturally airing the fabric. The dyed fabric has excellent color fastness and is good in dyeing uniformity and free from dyeing defects.

Description

technical field [0001] The invention relates to a method for dyeing real silk fabrics. Background technique [0002] In the existing dyeing method of real silk fabrics, the color fastness of the dyed fabrics is not high, the dyeing uniformity is not good, and colored flowers are easy to occur. Contents of the invention [0003] The object of the present invention is to provide a method for dyeing silk fabrics, the dyed fabrics have excellent color fastness to chlorine bleaching, color fastness to washing, color fastness to dry cleaning, color fastness to rubbing, color fastness to sunlight, perspiration, etc. Color fastness, color fastness to water stains, color fastness to non-chlorine bleaching, and good dyeing uniformity, colorless flowers. [0004] In order to achieve the above object, the technical solution of the present invention is to design a kind of dyeing method of real silk fabric, comprising the steps: [0005] 1) Add 1 to 2 parts by weight of titanium dioxi...
