• Yarn-dyed fabrics 7# and 8# were manufactured according to the method of Example 1. The difference from Example 1 is that:
• Step 2) The desizing temperature in the first desizing is 92.5°C and 90.5°C to prepare yarn-dyed fabrics 7# and 8#, respectively.
• Yarn-dyed fabric 7# performance test the fabric is stained and the quality is unqualified.
• Yarn-dyed fabric 8# performance test The cotton feel is poor, and the desizing is not clean.
• Yarn-dyed fabric 9# was manufactured according to the method of Example 1. The difference from Example 1 is that:
• step 2) no antibacterial auxiliary agent is added, and 4wt ⁇ of antibacterial agent is added in step 5) to make a yarn-dyed fabric 9#.
• the desizing temperature is 92.5°C and 90.5°C respectively to make yarn-dyed fabrics 7# and 8#.
• Yarn-dyed fabric 9# performance test color fastness to soaping level 5, color fastness to rubbing level 5, color fastness to sublimation level 5; ironing shrinkage rate is not higher than 1%; cotton feel relative to yarn-dyed fabric 1# Poor dryness.
• Yarn-dyed fabric 10# was manufactured according to the method of Example 1. The difference from Example 1 is that:
• Step 2) First desizing:
• the desizing mixture I includes 4wt% strong alkali and 2-3wt% desizing agent.
• Step 4) The second desizing: the desizing mixture II is used for intermittent desizing (washing in the tank), the temperature of the second desizing is 60-90°C and the time is not more than 45min, and the desizing mixture II includes 6g/L Sodium hydroxide, 2g/L sodium hydroxide and 1g/L degreaser, wash once with water, add 1g/L softener, wash once with water, and drain water twice or until the water is clean.
• Yarn-dyed fabric 10# performance test soaping color fastness level 3, rubbing color fastness level 3, sublimation color fastness level 3; ironing shrinkage rate is higher than 5%; good cotton feel.
• the yarn-dyed fabric 11# was manufactured according to the method of Example 1. The difference from Example 1 is that steps 4) and 5) are not performed.
• Yarn-dyed fabric 11# performance test color fastness to soaping 4, color fastness to rubbing 4, color fastness to sublimation 4; ironing shrinkage rate is higher than 5%; cotton feel is poor.
• the yarn-dyed fabric 12# was manufactured according to the method of Example 1. The difference from Example 1 is that step 2) is not performed.
• Yarn-dyed fabric 12# performance test soaping fastness level 3, rubbing fastness level 3, sublimation fastness level 3; ironing shrinkage rate is higher than 6%; cotton feel is poor.
