2) Experimental procedure

(1) Before the experiment, fabrics with different colors are pre-washed for 3 times by adopting a standard washing machine according to different dyes so as to remove redundant dyes on the fabrics, dried, ironed and flattened, and cut into 10cm multiplied by 10cm cloth pieces.

(2) Before formal washing, the values of L, a and b before washing of each cloth piece are measured by using a color difference meter.

(3) In each set of experiments, 3 pieces of cloth were placed for each color of each component fabric to simulate the actual home laundry environment. The multi-effect laundry detergent and the national standard laundry detergent are respectively adopted to continuously and repeatedly wash for 5 times under the experimental condition, and the difference delta L, delta a, delta b and the total color difference delta E of the values of L, a and b before and after washing of each cloth piece are calculated. And carrying out subjective color change rating on the washed cloth pieces and the original cloth pieces in a standard light source box.

(4) Study on antibacterial effect of color fixative

The size of the zone of inhibition was determined by oxford cup diffusion. 100 mu.l of 106 CFU/ml bacterial suspension is added to the sterilized and solidified beef extract peptone solid medium and is evenly coated. The Oxford cups with the diameter of 6 mm are placed on a flat plate, 100 mu l of 10 mg/ml test solution is added into each Oxford cup, and the size of the inhibition zone is measured after 24 h is cultured at the constant temperature of 37 ℃. Three oxford cups were placed in parallel on each plate. DMSO was used as a negative control, and ampicillin sodium (10. Mu.g/ml) was used as a positive control.
