Embodiment 1

[0039] 1. Cloth: prepare elastic cloth containing 43wt.% elastic fiber, and prepare a dyeing and finishing composition.

[0040] 2. Dye composition: Dissolve the dye LANASYN Turquoise M-5G in the water of the dyeing machine, adjust to a concentration of 0.5wt.%, add 0.15wt.% ion modifier, 0.5% dye retarder, and adjust the pH value to 4.

[0041] 3. Temperature curve: The initial temperature is room temperature, and the dyeing and finishing composition is heated to a dyeing temperature between 85 and 115°C at a heating rate of 0.5 to 1.0°C / min, and the prepared elastic fabric is added to the dyeing machine , and maintain for 20 to 60 minutes. The dyeing and finishing composition is cooled to a temperature between 70 and 60°C at a cooling rate of 1 to 1.5°C / min.

[0042] 4. Washing: Wash the dyed and finished elastic fabric with water to remove excess dye. The washing time is about 3 minutes, preferably until no pigment is leached out visible to the naked eye.

[0043] 5. Col...

Embodiment 2 to 4

[0049] The detailed steps are as described in the first embodiment. In addition, in the following examples, the same elastic cloth as in Example 1 and different concentrations of ion modifiers were also used for experiments.

Abstract

The invention discloses a dyeing and finishing composition and a dyeing and finishing method for elastic cloth. The dyeing and finishing method for the elastic cloth comprises the following steps of (a) providing the elastic cloth which comprises elastic fibers; and (b) impregnating the elastic cloth in the dyeing and finishing composition. The dyeing and finishing composition comprises an ion modifier and a dye, wherein the elastic fibers of the elastic cloth have first ions with first charge by contacting with the ion modifier, the dye has second ions, and the second ions have second chargeopposite to the first charge. Ionic bonds are generated between the first ions of the elastic fibers and the second ions of the dye for bonding, so that the dyed and finished elastic cloth can be obtained. Therefore, a traditional coloring mode depending on pollution of the elastic fibers can be improved, and the water fastness, the washing fastness, the perspiration fastness and the rubbing fastness can be kept at the optimal level.

Description

technical field [0001] The invention relates to a dyeing and finishing composition and a dyeing and finishing method, in particular to a dyeing and finishing composition and a dyeing and finishing method for elastic cloth. Background technique [0002] Fitting and comfortable stretch fabrics have become an essential element of fashion apparel and sportswear, so there is an increasing demand for stretch fabrics with elastic tensile strength, resistance to washing, sunlight, and abrasion. Elastic fabrics are generally woven from elastic fibers and ordinary fibers. Elastic fibers are generally called "OP". They have strong elasticity and can stretch up to 500%. After stretching, they can return to their original shape, and have a larger Strength, with excellent wear resistance. [0003] However, the dyeing and finishing methods of the prior art cannot evenly dye the elastic fibers when the cloth contains elastic fibers. Problems such as good quality and difference in color an...
