Embodiment 1
[0057] In this example, a knitted yarn of the fabric is a polyester DTY150D / 72F.
[0058] like figure 2 As shown, the front treatment process of the A step fabric of the fabric is: adding water in the dyeing cylinder and tapered to 85 ° C in water, and then adding the previous treatment auxiliaries and continues to heat up to 105 ° C, treatment 10 min, subsequent row Liquid; the front assistant aid includes refining agent 1 g / L, sodium hydroxide 3 g / L, sodium carbonate 3g / L, insurance powder 1g / L;
[0059] The dyeing process of the step B of the fabric is: adding auxiliary ice acetic acid 0.6 g / L, high-efficiency coaled agent 1.2g / l runs 10 min, then add 4g / L of dye to operate 10 min, 3 ° C / min temperature rise to 90 ° C, Then hewes to 105 ° C for 10 min at 1.0 ° C / min, and then heated to 135 ° C for 40 min at 1.5 ° C / min.
[0060] The step C reduction cleaning process of the fabric is 4 g / L of sodium hydroxide, 4g / L of the insurance powder, 10 min after ...
Embodiment 2
[0066] This example gives a dyeing process of a two-sided blue polyester fabric that is a polyester DTY100D / 72F, and the fabric is relative to Example 1, and the fabric is low, and the color depth is relatively. shallow.
[0067] like image 3 As shown, the front treatment process of the A step fabric of the fabric is: adding water in the dyeing cylinder and tapes at 2 ° C / L to 80 ° C, and then adding the pre-treatment auxiliaries and continues to heat up to 100 ° C, 10 min, then row Liquid; the front assistant aid includes 0.8 g / l, sodium hydroxide 2 g / L, sodium carbonate 2g / L, insurance powder 1g / L;
[0068] The dyeing process of step B of this fabric is: adding auxiliary ice acetic acid 0.4 g / L, high-efficiency coaled agent 0.8 g / l to operate 10 min, then add 2 g / L of dye to operate 10 min, 3 ° C / min temperature rise to 90 ° C, Then he was warmed to 10 min after 1.0 ° C / min, and then heated to 130 ° C for 30 min at 1.5 ° C / min.
[0069] The process of ste...
