[0026] Use the mixed fabric with modal and spun silk in the warp direction and nylon in the weft direction as the fabric to be dyed for dyeing. The dyeing steps are as follows:

[0027] (1) Add acid dye, 1g / L leveling agent and 1g / L ammonium sulfate in water to make an acidic dye solution, keep the pH value of the acidic dye solution at 4-6, and the temperature is 30°C, add the dye to be dyed Fabric, bath ratio 1:10, heat preservation dyeing 5min; acid dyes include the following components: 4% owf acid K-PBL gray 200%, 1.2% owf acid K-GLS scarlet 150% and 3% owfK-GLN yellow 250%;

[0028] (2) Continue to heat up to 98°C at a heating rate of 2.5°C / min, keep warm and dye for 40 minutes, and then obtain a dyed fabric after cooling down, washing with water, and soaping;

[0029] (3) Add reactive dyes, 15g / l of soda ash and 15g / L of sodium sulfate in water to prepare a reactive dye solution, keep the pH value of the reactive dye solution at 10-12, and the temperature is 20°C, add ...

Embodiment 2

[0032] Use the mixed fabric with modal and spun silk in the warp direction and nylon in the weft direction as the fabric to be dyed for dyeing. The dyeing steps are as follows:

[0033] (1) Add acid dye, 2g / L leveling agent, 2g / L ammonium sulfate and 0.5g / L light stabilizer to the water to make an acidic dye solution. The light stabilizer is light stabilizer 783 to keep the acidity The pH value of the dyeing solution is 4-6, the temperature is 40°C, add the fabric to be dyed, the bath ratio is 1:15, and keep warm for 1 minute; the dosage of each component of the acid dye is as follows: 3% owf acid K-PBL ash 200%, 1.5% owf acid K-GLS scarlet 150% and 4% owf K-GLN yellow 250%;

[0034] (2) Continue to heat up to 108°C at a heating rate of 3.5°C / min, keep warm and dye for 30 minutes, and then obtain a dyed fabric after cooling down, washing with water, and soaping;

[0035] (3) Add reactive dyes, 20g / l soda ash and 20g / L sodium sulfate to water to prepare a reactive dye solution...

Embodiment 3

[0038] Use cotton in the warp direction and nylon and silk in the weft direction as the fabric to be dyed for dyeing. The dyeing steps are as follows:

[0039] (1) Add acid dye, 3g / L leveling agent, 3g / L ammonium sulfate and 2g / L photostabilizer in water to configure an acidic dye liquor, the photostabilizer is photostabilizer 119 and photostabilizer Keep the pH value of the acid dye solution at 4-6, and the temperature is 35°C, add the fabric to be dyed, the liquor ratio is 1:10, and keep warm for 3 minutes; the dosage of each component of the acid dye is as follows: 5 % owf Acid K-PBL Gray 200%, 1.0% owf Acid K-GLS Scarlet Red 150% and 2% owf K-GLN Yellow 250%;

[0040] (2) Continue to heat up to 90°C at a heating rate of 2.0°C / min, keep warm and dye for 50 minutes, then cool down, wash with water, and soap to obtain a dyed fabric;

[0041] (3) Add reactive dyes, 25g / l of soda ash and 25g / L of sodium sulfate in water to prepare a reactive dye solution, keep the pH value of ...

Abstract

The invention relates to the technical field of dyeing of textile fabric, and discloses a dyeing method of light, elastic and comfortable blended fabric. The dyeing method comprises the following steps: (1) adding an acid dye into water to prepare an acid dye solution, adding the fabric to be dyed according to a bath ratio of 1: (10-15), keeping warm and dyeing for 1-5 min; (2) continuously raising the temperature to 90-108 DEG C, keeping warm and dyeing for 30-50 minutes, and then cooling, washing with water and soaping to obtain primarily dyed fabric; (3) adding an active dye into water to prepare an active dye solution, adding the primarily dyed fabric according to a bath ratio of 1: (7-10), keeping warm and dyeing for 1-5 minutes, and (4) continuously heating to 50-70 DEG C, keeping warm and dyeing for 20-40 minutes, and then cooling, washing with water and soaping to obtain finished dyed fabric. The blended fabric dyed by the method is high in color fastness and uniform in dyeing.

Description

technical field [0001] The invention relates to the technical field of dyeing of textile fabrics, in particular to a method for dyeing light and comfortable blended fabrics and its application. Background technique [0002] At present, most of the fabrics commonly used in textile fabrics on the market are mainly cotton, polyester, silk, nylon and regenerated cellulose fibers. [0003] Nylon, cotton, silk, and interwoven (or blended) fabrics have both the advantages of various fibers and are complementary to each other. They have good elasticity, high strength, light weight, soft hand feeling, good moisture absorption and air permeability, etc., and have won consumers' attention. favorite. As we all know, cotton is dyed with reactive dyes, brocade and silk are dyed with acid dyes, but because reactive dyes are dyed under alkaline conditions, acid dyes must be dyed under acidic conditions. The dyeing of blended fabrics brings great difficulties, and generally the reactive dy...
