Embodiment 1
[0045] Embodiment 1, weak acid acid dye dyeing
[0046] Put 20D×20D×380T nylon 56 nylon fabric into the overflow dyeing machine, adjust the water temperature in the dyeing machine at 40°C and start the cycle, and add weak acidic acid dye F-2R (3%, weight to the fabric) during dyeing Make a dye solution with acid leveling agent FS-610 (0.5g / l), add it into the dyeing machine, slowly raise the temperature for 1°C / 1 minute to 60°C, then add dyeing acid FS-309 (0.1g / l), continue Raise the temperature by 1°C / min to 80°C and keep it warm for 60 minutes. After the color is qualified, post-processing is carried out.
[0047] The various color fastness indexes of the fabrics dyed in this embodiment are as shown in Table 1.
[0048] It can be seen from the data in Table 1 that the fastness of dyeing meets the requirements.
Embodiment 2
[0049] Embodiment 2, neutral dye dyeing
[0050] Nylon-56 dyeing, dyeing with 1:2 metal complex dyes (neutral dyes) needs to pickle the nylon fabric with dyeing acid first, then let it go, and then dye it.
[0051]Put the 20D×20D×350T nylon 56 nylon fabric into the overflow dyeing machine and pickle it with dyeing acid FS-309 (0.2g / l), adjust the water temperature in the dyeing machine at 40°C and start the cycle. 1: Type 2 metal complex dye (3.5% BL black, weight to fabric) and acid leveling agent FS-610 (0.1g / l) are prepared into a dye solution and added to the dyeing machine, and the temperature is slowly increased by 1°C / 1 minute to 80°C and keep warm for 60 minutes. After the color is qualified, post-processing is carried out.
[0052] The various color fastness indexes of the fabrics dyed in this embodiment are as shown in Table 1.
[0053] It can be seen from the data in Table 1 that the fastness of dyeing meets the requirements.
Embodiment 3
[0054] Embodiment 3, K type reactive dye dyeing
[0055] Nylon 56 dyeing is suitable for reactive dyes of high temperature type K.
[0056] 20D × 20D × 350T nylon 56 fabric is loaded into the overflow dyeing machine, adjust the water temperature in the dyeing machine to start the cycle at 40 ° C, when dyeing, K-type reactive dye (reactive brilliant red 3B, 4%, weight to the fabric) and Leveling agent O-15 (0.5g / l) is made into a dye solution and added to the dyeing machine, and the temperature is raised slowly for 1°C / 1 minute to 60°C. Add dyeing acid FS-309 to 0.1g / l, adjust the pH value to 6, and continue Raise the temperature at 1°C / min to 80°C and keep it warm for 60 minutes. After the color is qualified, post-processing is carried out.
[0057] The various color fastness indexes of the fabrics dyed in this embodiment are as shown in Table 1.
[0058] It can be seen from the data in Table 1 that the fastness of dyeing meets the requirements.
