Color absorption performance detection test:
sample preparation: 3 pieces of small pieces of 8cm x 8cm in size were cut out from the color-absorbing nonwoven fabrics in examples 1 to 3 and comparative example 1 as samples.
The test method comprises the following steps: the washing process of the washing machine is simulated, a sample is placed in a reactive dye solution, absorbance (A0) of the sample is measured at the maximum absorption wavelength by a UV1102 ultraviolet spectrophotometer, then the sample is placed in the sample, the sample is turned over at a speed of 50rpm for 10min, the sample is filtered out, absorbance (A1) of residual liquid after color absorption is measured, initial color absorption rate is measured according to (1-A1/A0) x 100%, and the higher the initial color absorption rate is, the higher the color absorption performance is. Each group of samples was measured 3 times, and the average value thereof was taken as a test result, and the test result is shown in table 1.
Preparing a reactive dye solution: the reactive dye TP-RV brilliant blue dye purchased from the Buddha Alternarix industrial and trade company, is dissolved in water to obtain a reactive dye solution with the mass concentration of 0.2%.
