Embodiment 1

[0028] Kapok pre-treatment

[0029] Kapok→alkali treatment→washing→drying→hydrogen peroxide bleaching treatment→washing→drying.

[0030] Kapok loose fiber

[0031]Both the alkali treatment solution and the hydrogen peroxide bleaching treatment solution use water as a solvent, and their components:

[0032] (1) Alkali treatment solution: sodium hydroxide, 10g / L; penetrant JFC, 1g / L; Pingpinga O, 1g / L; sodium silicate, 2g / L; liquor ratio, 1:30.

[0033] (2) Hydrogen peroxide bleaching treatment solution: 30% hydrogen peroxide, 2g / L; Oxygen bleach stabilizer sodium silicate, 1g / L; Regulate pH value with sodium hydroxide to be 10.5~11; Bath ratio, 1: 30.

[0034] Specific operation:

[0035] Weigh a certain amount of kapok loose fiber, immerse in the alkali treatment solution, treat at 100°C for 120min, take it out, wash it with water, and dry it. Then immerse in the hydrogen peroxide bleaching treatment solution, treat at 90°C for 60 minutes, take it out, wash with water, and...

Embodiment 2

[0037] Direct Dyeing of Kapok Fiber

[0038] Pre-treated kapok fibers→dyeing with direct dyes→washing→drying.

[0039] Kapok loose fiber

[0040] Alkali treatment solution, hydrogen peroxide bleaching treatment solution, and direct dye dyeing solution all use water as a solvent, and their components:

[0041] (1) The preparation of alkali treatment solution and hydrogen peroxide bleach treatment solution is the same as in Example 1.

[0042] (2) Dyeing solution of direct dye: direct dye (Sarafinier blue), 1% (o.w.f); penetrant JFC, 0.5g / L; electrolyte sodium chloride, 20g / L; liquor ratio, 1:50.

[0043] Specific operation:

[0044] Alkali treatment and hydrogen peroxide bleaching treatment are as embodiment 1.

[0045] Shake the dye solution for direct dyeing at 50°C for 5-10 minutes, then take the kapok fiber after quantitative pretreatment, immerse it in the dye solution, dye it at 50°C for 90 minutes, test the dye uptake rate, take it out, wash it with water, and dry it...

Embodiment 3

[0047] Dyeing of kapok fiber with reactive dyes

[0048] Pre-treated kapok fiber→dyeing with reactive dyes→washing→drying.

[0049] Kapok loose fiber

[0050] Alkali treatment solution, hydrogen peroxide bleaching treatment solution, reactive dye dyeing solution all use water as solvent, and its components:

[0051] (1) Alkali treatment solution and hydrogen peroxide bleach treatment solution are prepared as in Example 1.

[0052] (2) reactive dye dyeing solution: reactive dye (Ciba FN-R), 1% (o.w.f); penetrant JFC, 2g / L; electrolyte sodium chloride, 20g / L; liquor ratio, 1:50.

[0053] Specific operation:

[0054] Alkali treatment and hydrogen peroxide bleaching treatment are as embodiment 1.

[0055] Shake the reactive dye solution at 60°C for 5-10 minutes, then take the kapok fiber after quantitative pretreatment, immerse it in the dye solution, and dye it at 60°C for 30 minutes to test the dye uptake rate, then add alkali agent sodium carbonate (10g / L), fix the color a...

Abstract

The invention relates to a rare earth mordant dyeing method for kapok fibers and textiles thereof. The method comprises the following steps: pre-treating kapok textile so as to remove some waxy xubstances, impurities and the like on the surface of the kapok fiber and achieve certain whiteness; and then adding a complexing rare earth mordant into a dye bath of the pretreated kapok textile, and mordant dyeing the kapok textile. Compared with the prior art, according to the dyeing method of the invention, the dyeing of the kapok fibers and textiles thereof is not limited to direct dyes and can also be used for other anionic dyes such as reactive dyes and the like, and the problems of low rate of dye-uptake, poor level-dyeing property, poor deep-color dyeing effect, poor dyeing fastness and the like are overcome.

Description

technical field [0001] The invention relates to a dyeing method for textile fibers, in particular to a method for improving the dyeing performance of kapok fiber and its textiles. Rare earth mordant dyeing of kapok textiles can improve the dye uptake rate of dyes, the fixation rate of dyes, and the dyed textiles. color fastness. Background technique [0002] Kapok fiber is the fruit fiber of the woody plant kapok tree, attached to the inner wall of the kapok capsule shell, developed and grown from the inner wall cells. The adhesion force between kapok fiber and fruit is small, so special primary processing equipment is generally not required, and kapok seeds can sink to the bottom by themselves, and kapok fiber can be obtained only by sieving in baskets. Kapok fiber has many natural characteristics such as green ecology, hollow and ultra-light, good warmth retention, natural antibacterial, moisture absorption and moisture conduction. Kapok fiber is difficult to spin alone ...
