Embodiment 1

[0027] (1) Pretreatment: add the following components to the water to prepare a pretreatment agent: 2g / l refining agent, 2g / l caustic soda, 2g / l hydrogen peroxide, 4g / l sodium hypochlorite, and scorch the flame retardant blended fabric for 50min at 90°C Wherein, the refining agent is composed of the following parts by weight: 50 parts of nonylphenol polyoxyethylene ether, 50 parts of cetyl alcohol polyoxyethylene ether, 20 parts of Turkish red oil;

[0028] (2) First bath dyeing: move the flame-retardant blended fabric obtained in step (1) into the first dyeing vat, which contains 2g / L acetic acid, add cationic fluorescent yellow X-10GFF with 3% weight of the flame-retardant blended fabric, and heat to 70 After ℃, heat up to 100℃ at a heating rate of 1℃ / min, keep warm for 45min, wash with water, soap (neutral soaping agent 2g / L, 40±2℃, soap for 30min), and wash with water;

[0029] (3) second bath dyeing: move the flame-retardant blended fabric obtained in step (2) into the se...

Embodiment 2

[0032] According to the method described in Example 1, the refining agent is replaced by the following components in parts by weight: 60 parts of nonylphenol polyoxyethylene ether and 60 parts of cetyl alcohol polyoxyethylene ether.

Embodiment 3

[0034] According to the method described in Example 1, the refining agent is replaced by the following components by weight: 100 parts of nonylphenol polyoxyethylene ether, 20 parts of Turkish red oil.

Abstract

The invention relates to a dyeing method of a flame retardant blended fabric. The method comprises the following steps: (1) carrying out pretreatment, namely, boiling the flame retardant blended fabric in a pretreatment agent for 30-50 minutes at the temperature of 70-95 DEG C; (2) dyeing in a first bath, namely, transferring the flame retardant blended fabric obtained in the step (1) into a first dye vat; and (3) dyeing in a second bath, namely, transferring the flame retardant blended fabric obtained in the step (2) into a second dye vat. The flame retardant blended fabric comprises the following components in parts by weight: 40-60 parts of meta-position aramid fiber and 40-60 parts of flame retardant viscose fiber. According to the dyeing and finishing method, in the process of dyeing in the first bath, the meta-position aramid fiber is dyed, and in the process of dyeing in the second bath, the flame retardant viscose fiber is dyed, so that different dyeing and finishing processes are carried out on the two fibers with different functions; the dyeing method has the advantages of being uniform in dyeing, stable, washable, good in flame retardant property and the like.

Description

technical field [0001] The invention relates to a dyeing method of a fabric, in particular to a dyeing method of a flame-retardant blended fabric. Background technique [0002] The process of chemically treating textile materials (fibers, yarns and fabrics) is also commonly known as printing and dyeing in modern times. Together with spinning, weaving or knitting, dyeing and finishing form the whole process of textile production. Dyeing and finishing include pretreatment, dyeing, printing and finishing. The quality of dyeing and finishing has an important impact on the use value of textiles. Pretreatment is also called scouring and bleaching. Its main purpose is to remove impurities on textile materials, so that the subsequent dyeing, printing, and finishing processes can be carried out smoothly, and the expected processing effect can be obtained. Dyeing is to make textile materials have a certain color through the physical or chemical combination of dyes and fibers. Prin...
