The finished fabrics of examples 1 to 5, comparative examples 1 to 7, which were finished by dyeing and finishing, were tested, and the results are shown in tables 3 and 4:
TABLE 3
TABLE 4
From the data in tables 3 and 4, it can be seen that:
1) by adopting the continuous pad dyeing process, the dyed nylon 66 fabric has the advantages of high rubbing fastness, high soaping fastness, high chlorine fastness, high perspiration fastness and water fastness, the cloth cover is uniform and soft, and meanwhile, the continuous pad dyeing process has the advantages of short dyeing time and high working efficiency.
2) From a comparison of the data of example 1 and comparative examples 1 to 4, it can be seen that:
when the using amount of the anhydrous sodium sulphate is less, the dry and wet rubbing fastness of the product is low by 1-2 grades, the soaping fastness, the chlorine bleaching fastness, the perspiration fastness, the water fastness and the like are all low by 1-2 grades, the color difference of the product is larger, the production control is inconvenient, and the cloth cover is uneven. And the less the dosage, the worse the product fastness index, the larger the color difference before and after production, when the dosage of the anhydrous sodium sulphate is too much, the effects can not be improved, and the product strength index can be reduced.
3) From a comparison of the data of example 1 and comparative examples 5 to 7, it can be seen that:
when glacial acetic acid HAC is not adopted in the color fixing solution, the dry and wet rubbing fastness of the product is about 1 grade, the soaping fastness, the chlorine bleaching fastness, the perspiration fastness, the water fastness and the like are all about 0.5-1.5 grade, and the front-back color difference of the product is large.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
