Test case
The samples prepared in the above examples and comparative examples were subjected to performance testing:
(1) The K/S value of the sample is tested by a color measuring and matching instrument, and the test result is shown in table 1;
(2) The samples were tested for wash fastness to ISO 105-C06:2010 and the test results are shown in Table 1;
(3) The samples were tested for dry/wet crocking color fastness according to GB/T3920-1997 and the test results are shown in Table 1;
(4) The leveling property of the sample is tested by adopting a color measuring and matching instrument, 11 positions are randomly measured on the sample, 10 color difference values delta E are calculated by software, and the average value of the 10 color difference values delta E is calculated To characterize, the test results are shown in table 1;
(5) The breaking strength of the sample is tested according to GB/T3923.1-2013, and the test result is shown in Table 1;
TABLE 1
In the above table, in comparative example 1, since only disperse orange S-4RL is present in the dye liquor, the disperse dye cannot dye cotton fiber during dyeing, and thus, the dyed acetate fiber and cotton fiber in the cotton fiber knitted fabric are not dyed, and the K/S value thereof cannot be measured; similarly, in comparative example 2, since only the reactive orange TCR-D is contained in the dye liquor, the reactive dye is difficult to dye the acetate fiber in the dyeing process, and thus the acetate fiber in the dyed acetate fiber and cotton fiber knitted fabric is not dyed and the K/S value thereof cannot be measured; in comparative example 3, although the dispersion orange S-4RL and the reactive orange TCR-D were contained, the dyeing medium did not contain water, and the reactive dye could not be dissolved in the liquid wax, so that the dyed acetate fiber and the cotton fiber in the cotton fiber knitted fabric could not be measured for K/S value, and since one of the dyed samples in comparative examples 1,2 and 3 had one fiber undyed, the leveling property could not be measured.
As can be seen from the results in Table 1, the dyeing method of the invention has good dyeing effect on the blended fabric of the acetate fiber and the cotton fiber, can obtain good dye-uptake, leveling property, washing fastness and dry rubbing fastness, and has the advantages of short and efficient process flow, reduced consumption of dyeing medium water, environmental protection and energy saving.
The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, a number of simple variants of the technical solution of the invention are possible, including combinations of the individual technical features in any other suitable way, which simple variants and combinations should likewise be regarded as being disclosed by the invention, all falling within the scope of protection of the invention.
