Embodiment 1

[0048] 32S black cotton plain weave is selected as the fabric for mass production for dark fabrics.

[0049] Soaping: In this step, the dispersant standard is 0.5% (owf), and the dark fabric is soaped at 80°C and kept warm for 20 minutes.

[0050] Water washing: In this step, cool down to drain the dispersant working solution, and wash twice with water (two tanks).

[0051] Dehydration: dehydration machine dehydration.

[0052] Spraying: Spray the working solution of wet rub fastness improver with a concentration of 70g / L onto the dark fabric.

[0053] Drying: The drying temperature is 100°C.

[0054] Result evaluation: the wet rubbing fastness before treatment is grade 2, and the wet rubbing fastness after treatment reaches grade 3.

Embodiment 2

[0056] For the dark fabric, 21S black cotton 2×2 sweater fabric is used for mass production.

[0057] Soaping: In this step, the dispersant standard is 1.0% (owf), and the dark fabric is soaped at 80°C and kept warm for 20 minutes.

[0058] Water washing: In this step, cool down to drain the dispersant working solution, and wash twice with water (two tanks).

[0059] Dehydration: dehydration machine dehydration.

[0060] Spraying: Spray the working solution of wet rub fastness improver with a concentration of 70g / L onto the dark fabric.

[0061] Drying: The drying temperature is 100°C.

[0062] Result evaluation: the wet rubbing fastness before treatment is grade 1-2, and the wet rubbing fastness after treatment reaches grade 3.

Embodiment 3

[0064] 21S bright red cotton 2×2 rib fabric is selected as the fabric for mass production for the dark fabric.

[0065] Soaping: In this step, the dispersant standard is 0.8% (owf), and the dark fabric is soaped at 80°C and kept warm for 20 minutes.

[0066] Water washing: In this step, cool down to drain the dispersant working solution, and wash twice with water (two tanks).

[0067] Dehydration: dehydration machine dehydration.

[0068] Spray: Spray the working solution of wet rub fastness improver with a concentration of 90g / L onto the dark fabric.

[0069] Drying: The drying temperature is 100°C.

[0070] Result evaluation: the wet rubbing fastness before treatment is grade 2, and the wet rubbing fastness after treatment reaches grade 3.

Abstract

The invention provides a post-treatment method for improving wet rubbing fastness of deep-color fabric, the method comprises the following steps: feeding cold water into an auxiliary cylinder, starting a stirrer, adding a dispersing agent, and stirring until the dispersing agent is completely dissolved to obtain a dispersing agent working solution; adding the dispersing agent working solution into a dye vat filled with the deep-color fabric, soaping the deep-color fabric under a preset temperature condition, and keeping the temperature for a preset time; discharging the dispersing agent working solution, and cooling and washing the deep-color fabric; dehydrating the deep-color fabric by using a dehydrator; feeding cold water into an auxiliary cylinder, starting a stirrer, adding a wet rubbing fastness improver, and uniformly stirring to obtain a wet rubbing fastness improver working solution; spraying the wet rubbing fastness improver working solution to the deep-color fabric; and drying the deep-color fabric sprayed with the wet rubbing fastness improver working solution by using a drying process. Compared with the prior art, the post-treatment method for improving the wet rubbing fastness of the deep-color fabric has the advantages that the wet rubbing fastness is effectively improved, the production cost is low, and the method is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a post-treatment method for improving the wet rubbing fastness of dark-colored fabrics. Background technique [0002] Reactive dyes have bright colors, complete chromatograms, simple operation, and all fastnesses can reach an excellent level. With the development, the quality of various fabrics has been improved, especially the wet rubbing fastness test has put forward higher requirements. Generally, the wet rubbing fastness of dark colors must reach grade 3 or above. [0003] The current common practices in the industry include: choosing dyes with good fastness; fully soaping; choosing high-fastness fixing agents, etc. However, in the methods in the prior art, either the production cost is greatly increased, or the water consumption is increased to a large extent, and the energy consumption is large. [0004] Therefore, it is necessary to provide a new post...
