Embodiment 1
[0022] A method for dyeing pure cotton sheets with good color fastness, comprising the following steps:
[0023] (1) Pretreatment of pure cotton sheets: Soak the pure cotton sheets in ethanol solution for 30 minutes and ultrasonically treat them for 2 minutes, then take them out and dry them to constant weight;
[0024] (2) Plasma treatment: Add the pure cotton sheets treated in step (1) into the plasma treatment device for plasma treatment, and the treatment time is 3 minutes;
[0025] (3) Dyeing: Dyeing the pure cotton sheets processed in step (2), specifically: immerse the pure cotton sheets in the clear water of 300 parts by weight in the dyeing machine at room temperature, and then add 30 parts of plant dyes, 12 parts of methyl cellulose, 10 parts of glycerol, 2 parts of activated nano diatomite particles, 0.15 parts of Huang's polysaccharide titanium, the bath ratio is 12:1, and the pH of the dyeing solution is adjusted by a pH buffering agent. The value is adjusted to ...
