Embodiment 1

[0064] Adopt the following water-saving spray dyeing process according to the application to produce high color fastness yarn:

[0065] Yarn pretreatment: heat the polyester yarn in 0.2g / L sodium hypochlorite aqueous solution at a temperature of 90°C for 20 minutes with a bath ratio of 4, then wash it with cold water and drain the water with a bath ratio of 3 at a temperature of 90°C Set aside to dry.

[0066] Process A, spray-dyeing yarn: under the conditions of temperature of 70°C and pressure of 0.3MPa, the dyeing liquid is spray-dyeing polyester yarn at a flow rate of 40L / min, and one spray-dyeing acts on 12 yarns at the same time. Dry naturally after finishing;

[0067] Step B, steaming the yarn after spray dyeing: steaming the yarn treated in the step A at a temperature of 180° C. for 8 minutes and then cooling to obtain the steamed yarn;

[0068] Process C, washing the yarn after spray dyeing: soak the yarn obtained in the process B in water at 0°C for 3 minutes at a ...

Embodiment 2

[0075] Adopt the following water-saving spray dyeing process according to the application to produce high color fastness yarn:

[0076] Yarn pretreatment: heat the polyester yarn in 0.5g / L sodium hypochlorite aqueous solution at a temperature of 80°C for 30min with a bath ratio of 2, then wash it with cold water and drain the water with a bath ratio of 5 at a temperature of 85°C Set aside to dry.

[0077] Process A, spray-dyeing yarn: under the condition of temperature of 65°C and pressure of 0.6MPa, the dyeing liquid is spray-dyeing polyester yarn at a flow rate of 20L / min, and one spray-dyeing acts on 24 yarns at the same time. Dry naturally after finishing;

[0078] Step B, steaming the yarn after spray dyeing: steaming the yarn treated in the step A at a temperature of 170° C. for 10 minutes and then cooling to obtain the steamed yarn;

[0079] Process C, washing the yarn after spray dyeing: first soak the yarn obtained in the process B in -5°C water for 5 minutes, with ...

Embodiment 3

[0086] Adopt the following water-saving spray dyeing process according to the application to produce high color fastness yarn:

[0087] Yarn pretreatment: heat the polyester yarn in 0.2g / L sodium hypochlorite aqueous solution at a temperature of 80°C for 20min at a bath ratio of 2, then wash with cold water and drain the water at a temperature of 85°C Set aside to dry.

[0088] Process A, spray-dyeing yarn: under the condition of temperature of 65°C and pressure of 0.3 MPa, the dye solution in process B is spray-dyeing polyester yarn at a flow rate of 20 L / min, and one spray-dyeing effect is applied to 12 polyester yarns at the same time. On the yarn, dry it naturally after spraying and dyeing;

[0089] Step B, steaming the yarn after spray dyeing: steaming the yarn treated in the step A at a temperature of 170° C. for 8 minutes and then cooling to obtain the steamed yarn;

[0090] Process C, washing the yarn after spray dyeing: first soak the yarn obtained in the process B ...

Abstract

The invention relates to the field of yarn dyeing, and particularly discloses dye liquor for producing high-color-fastness yarn and a water-saving spray dyeing process thereof. The dye liquor is prepared from the following raw materials in parts by weight: 5-10 parts of disperse dye, 0.1-0.3 part of lanthanide chloride rare earth, 5-12 parts of dispersing agent, 20-40 parts of normal propyl alcohol, 20-35 parts of pigment printing paste, 3-5 parts of surfactant, 25-40 parts of glycerol, 6-8 parts of adhesive, 16-21 parts of resin, 10-25 parts of color fixing agent and 60-80 parts of water. The water-saving spray-dyeing process adopting the dye liquor comprises the following four steps of spray-dyeing yarns, ageing the yarns after spray-dyeing, washing the yarns after spray-dyeing, and shaping the yarns after spray-dyeing. According to the dye liquor, the bath ratio in the subsequent dye liquor utilization process can be small, and dyed yarn is high in color fastness; and in addition, the water-saving spray-dyeing technology has the advantages of being short in operation process and small in water consumption.

Description

technical field [0001] The application relates to the field of yarn dyeing, more specifically, it relates to a dye solution for producing yarn with high color fastness and a water-saving spray dyeing process thereof. Background technique [0002] Yarn is processed from various textile fibers into textiles with a certain fineness, which is suitable for weaving, rope making and embroidery. In order to make the yarn show the various colors that people need, it is necessary to dye the yarn. After dyeing, the color fastness is generally used to evaluate the dyeing effect of the dye solution on the yarn. Resistance to various actions during processing and use. [0003] The main components of the dyeing solution are mostly dyes, which are organic compounds that can dye the yarn into a certain color. Most of the dyes are water-soluble, and the reactive groups on the dye matrix themselves react with the active groups on the yarn, thereby It is fixed on the fiber to achieve the purp...
