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.

Abstract

The invention discloses an acid bath dyeing method of chinlon 56 fiber fabric. The method includes the following step that the chinlon 56 fiber fabric is dyed by means of a weak-acidity acidic dye, a 1:2 metal complex dye, a reactive dye or a dispersed dye, wherein the chinlon 56 fiber fabric is chinlon 56 filament or chinlon 56 short fiber fabric. The dyeing method of chinlon fiber has the advantages that vitrification temperature of chinlon 56 is 46 DEG C, vitrification temperature of chinlon 66 is 52 DEG C, and chinlon 56 is lower in vitrification temperature, higher in hygroscopicity and capable of being easily dyed. Normal dyeing temperature of chinlon 66 is 40-98 DEG C, and dyeing temperature of the chinlon 56 fiber fabric can be reduced to 40-80 DEG C. It is indicated from the dyeing process that temperature of chinlon 56 during dyeing is lower, so that more energy is saved; besides, the temperature of chinlon 56 during dyeing is lower, so damage to the fabric is smaller.

Description

technical field [0001] The invention relates to an acid bath dyeing method for nylon 56 fiber fabrics Background technique [0002] Nylon fabric is the first synthetic fiber to appear in the world. The appearance of nylon (foreign names include nylon, nylon, capron, etc.) makes textile fabrics look brand new. Its synthesis is a major breakthrough in the synthetic fiber industry. Nylon is a poly The domestic product name of amide fiber, it has many varieties, but the molecular structure contains the same amide group. The commonly used varieties are polycaprolactam for nylon-6, and polycaprolactam for nylon-66, which is formed by the polymerization of hexamethylenediamine and adipic acid. , Nylon 56 is a new type of polyamide fiber. Unlike nylon 66, which uses petroleum raw materials, it uses biological raw materials. Pentamethylenediamine is fermented from various starches and straw cellulose by bioengineering methods. Due to large quantities , low cost, it can replace hexam...
