Example Embodiment
[0045]Example 1
[0046]This embodiment provides a method of regenerating polyester, a bath staining - cleaning, the regenerated polyester, a bath staining - cleaning method comprising the steps of:
[0047](1) Place the regenerated polyester knitted material in the dyeing cylinder, and then add water to the addition of a mossifying agent K, the dispersant P, acetic acid and dye to obtain a dyeing liquid at 40 ° C, and then warm up at a constant rate of 1.5 ° C / min. At 130 ° C, it was finally dyed at a constant temperature of 130 ° C; wherein the bath ratio of the regenerated polyester needle fabric dyed liquid is 1:10; the dyeing fluid includes the following components by mass concentration: 4.1% (OWF) Dispersed Black ECT300%, 1.2% (OWF) dispersed dark blue HGL200%, 0.7% (OWF) dispersed red GS200%, 1.0 g / L of dispersing agent P, 1.5 g / L of the same-dye K, 0.5g / L's acetic acid;
[0048](2) After the dye was completed, the constant rate of 1.5 ° C / min was lowered to 80 ° C, and 2.0 ...
Example Embodiment
[0050]Example 2
[0051]This embodiment provides a method of regenerating polyester, a bath staining - cleaning, the regenerated polyester, a bath staining - cleaning method comprising the steps of:
[0052](1) Place the regenerated polyester knitted material in the dyeing cylinder, and then add water to the addition of a mossifying agent K, the dispersant P, acetic acid and dye to obtain a dyeing liquid at 40 ° C, and then warm up at a constant rate of 1.5 ° C / min. At 130 ° C, it was finally pregnant at a constant temperature of 130 ° C; wherein the bath ratio of the regenerated polyester needle fabric is 1:10; the dyeing fluid includes the following components by mass concentration: 3.0% (OWF) Dispersed Black ECT300%, 1.0% (OWF) dispersed dark blue HGL200%, 1.0% (OWF) dispersion of red GS200%, 1.0 g / L of dispersant P, 1.5 g / L of the same, the same, K, 0.5g / L's acetic acid;
[0053](2) After the dye was completed, the constant rate of 1.5 ° C / min was lowered to 80 ° C, and 2.0 g / ...
Example Embodiment
[0055]Example 3
[0056]This embodiment provides a method of regenerating polyester, a bath staining-cleaning, and the difference from Example 1 is only in that step (1), the constant rate of 2.5 ° C / min is heated to 130 ° C, and other steps are as in Example 1. .
