Embodiment 1
[0038] The chitosan solution that mass fraction is respectively 0.4%, 0.8%, 1.2%, is processed fabric by the method for step 1 respectively, then by the reactive dye dyeing method in step 2 and step 3, the fabric after processing is dyed, dyeing Process reference figure 1 , the fabric after dyeing is carried out dyeing performance test, and test result, when chitosan mass fraction is 0.4%, 0.8%, 1.2%, K / S value is respectively 18.5, 21.2, 22.3, it can be known that when chitosan When the mass fraction is about 0.8%, the fabric has the best dyeing depth.
Embodiment 2
[0040] When the chitosan solution with a mass fraction of 0.8% is at 40°C, 60°C, and 80°C, the fabric is treated according to the method of step 1, and then the treated fabric is dyed according to the reactive dye method in step 2 and step 3. The fabric is dyed, and the dyeing process refers to figure 1 , the dyed fabric was tested for dyeing performance. The test results showed that when the chitosan pretreatment temperature was 40°C, 60°C, and 80°C, the K / S values were 19.8, 23.1, and 22.8. It can be seen that when the chitosan When the pretreatment temperature of polysaccharide is about 60℃, the deep dyeing property of the fabric is the best.
Embodiment 3
[0042] With a chitosan solution with a mass fraction of 0.8%, the temperature is 60°C, when the pretreatment temperature is 8min, 16min, and 24min respectively, the fabric is treated according to the method of step 1, and then dyed with reactive dyes in step 2 and step 3 The method is to dye the treated fabric, and the dyeing process refers to figure 1, the fabric after dyeing is carried out dyeing performance test, test result, when chitosan pretreatment time is respectively 8min, 16min, 24min when K / S value is respectively 18.9, 22.7, 22.1, it can be known that when chitosan pretreatment When the treatment time is about 16 minutes, the deepness of the fabric is the best.
