Examples 2-5 the differences between example 1: the components of the slow release accelerant are calculated according to the parts by weight in the following table.
Examples 6 to 9 differ from example 1 in that: the wetting agents are listed below in terms of weight percent.
Comparative example
Comparative example 1 differs from example 1 in that no slow release accelerator was used in the dyeing process;
comparative example 2 differs from example 1 in that the sustained release accelerator is not treated with a wetting agent;
comparative example 3 differs from example 1 in that the dyeing process employed a conventional dyeing process and the dyeing equipment employed a conventional cold-rolling push-open dyeing machine.
Detection method
Staining time detection
By performing a dyeing test on a brocade and cotton fabric with the length of 100 meters, compared with the dyeing time of the comparative example 3, the dyeing time of the finished product in the example 1 is 6 hours, and the dyeing time of the product in the comparative example 3 is 10 hours.
Therefore, the process of the invention greatly shortens the dyeing time of the brocade and cotton fabrics.
Color fastness test
The light fastness, sublimation fastness and rubbing fastness of the dyed cloth were determined using GB/T8427-1998, GB/T3920-1997.
And (4) conclusion: the comparison in the table shows that the color fastness of the fabric dyed by the slow release promoter is obviously improved compared with the color fastness of the fabric dyed without the slow release promoter, and the slow release promoter has the effect of increasing the concentration of local electrolyte in the dyeing process so as to improve the dye uptake of the dye. And the comparison with the comparative example 2 shows that the slow release promoter treated by adding the wetting agent has better effect of promoting the dye uptake of the cloth.
