Embodiment 1

[0028] Milk protein fibers are treated as follows:

[0029] Firstly, the milk protein fiber after winding treatment is steamed and preformed: put the milk protein fiber into the steam box, vacuumize, inject steam into the box and steam for 100 minutes, the steam pressure is controlled at 0.3MPa, and the steaming temperature is controlled at 120 ℃, pre-shrink and set the milk protein, and keep it warm for 40 minutes after steaming;

[0030] Dyeing treatment

[0031] First add 1g / L chelating agent and 0.5g / L isopropanolamine, then add dye 10g / L, sodium sulfate 10 g / L, 0.1g / L leveling agent, adjust the pH value of the dyeing solution 6. The bath ratio is 20:1. Heat the dye solution to 60°C and dye for 15 minutes, then add 0.1 g / L dyeing aid and 0.1 g / L hydroxypropyl methylcellulose, dye for 10 minutes, and then Continue to raise the temperature of the dyeing liquor, and after raising the temperature of the dyeing liquor to 90°C at 5°C / min, keep the temperature for 60 minutes to...

Embodiment 2

[0044] (1) Pretreatment: steaming pre-setting: put the milk protein fiber into the steam box, vacuumize, inject steam into the box and steam for 80 minutes, the steam pressure is controlled at 0.4MPa, and the steaming temperature is controlled at 120°C. The protein is pre-shrunk and shaped, and then kept warm for 30 minutes after steaming;

[0045] (2) Dyeing treatment:

[0046] (1) First add 1.5g / L chelating agent and 1g / L isopropanolamine, then add dye 30g / L, sodium sulfate 20 g / L, 0.2 g / L leveling agent to adjust the dyeing liquor The pH value is 6.5, the liquor ratio is 30:1,

[0047] (2) Warm up the dye solution to 60°C, dye for 20 minutes, then add dyeing assistant 0.5 g / L and 0.1 g / L hydroxypropyl methylcellulose, and dye for 15 minutes,

[0048] (3) Then continue to raise the temperature of the dyeing liquor, after raising the temperature of the dyeing liquor to 90°C at 5°C / min, keep the temperature for 90 minutes, and then dye the fabric;

[0049] (3) Post-processi...

Abstract

The invention discloses a dyeing technology of milk protein fibers. The dyeing technology specifically comprises steps as follows: steaming presetting in pre-treatment, dyeing treatment, after-treatment and the like. According to the dyeing technology, through steaming presetting and addition of a chelating agent, isopropanolamine and hydroxypropyl methyl cellulose, the milk protein fibers are dyed more uniformly, the dyeing effect is better, and the grade is higher.

Description

[0001] technical field [0002] The invention relates to the technical field of textiles, in particular to a dyeing process of milk protein fibers. Background technique [0003] Milk protein fiber contains 10 kinds of amino acids that are beneficial to the human body, and contains protein natural moisturizing factors, so it can nourish the skin and make the skin soft and smooth. Milk protein fiber has a luster like silk and a soft feel like cashmere; it also has natural moisture absorption and moisture conductivity, making it smooth and comfortable to wear. In addition, milk protein fiber and its filaments are high-grade new fiber materials. Combining the advantages of protein fiber and chemical fiber, it has the characteristics of skin-friendly, skin-nourishing, moisture-absorbing and breathable, soft, bright luster, luxurious appearance, excellent physical and mechanical properties, and good spinnability. Milk protein fiber contains 10 kinds of amino acids that are benefi...
