Embodiment 1

[0029] First add the color paste and dispersant evenly into the water, then add the polymer emulsion and other additives in turn, and stir evenly at room temperature for 15 minutes until the color and suspended matter in the solution are evenly distributed. Its components are as follows:

[0030]

[0031] Dip 3.0mm×450g / m2 polyester needle-punched non-woven fabric into the finishing solution, use plastic rollers to press and control the pressure at about 0.3Mpa, and the rolled base fabric with glue is heated and shaped after finishing. , the setting temperature is 140-180°C, and the setting time is 10 minutes.

Embodiment 2

[0033] First add the color paste and dispersant evenly in the water, then add the polymer emulsion and other additives in turn, and stir evenly at room temperature for 15 minutes until the color and suspended matter in the solution are evenly distributed; its composition is as follows:

[0034]

[0035]

[0036] Dip 3.0mm×450g / m2 polyester needle-punched non-woven fabric into the finishing solution, use plastic rollers to press and control the pressure at about 0.3Mpa, and the rolled base fabric with glue is heated and shaped after finishing. , the setting temperature is 140-180°C, and the setting time is 10 minutes.

Embodiment 3

[0038] First add the color paste and dispersant evenly in the water, then add the polymer emulsion and other additives in turn, and stir evenly at room temperature for 15 minutes until the color and suspended matter in the solution are evenly distributed; its composition is as follows:

[0039]

[0040] Immerse the 4.0mm×520g / m2 polyester needle-punched nonwoven fabric in the finishing solution, use plastic rollers to press and control the pressure at about 0.3Mpa, and the rolled base fabric with glue is heated and shaped after finishing. , the setting temperature is 140-180°C, and the setting time is 10 minutes.

Abstract

The invention discloses a paint pad dyeing afterfinish liquid and a preparation method thereof. The paint pad dyeing afterfinish liquid is prepared by uniformly mixing the following components by weight: 50-200 parts of a polymer emulsion, 1-3 parts of a penetrant, 1-3 parts of color fixing agent, 50-200 parts of a migration inhibitor water solution, 0.5-1 part of a wetting agent, 1-2 parts of a dispersant, 50-200 parts of water, and 0-100 parts of color paste; the migration inhibitor water solution is selected from a hydroxypropyl methyl cellulose water solution; the concentration of hydroxypropyl methyl cellulose is 1-5 g / L. the paint pad dyeing afterfinish liquid and the preparation method are applicable to pad dyeing of products with the thickness of more than 1.0 mm in fields such as textile, non-woven and composite materials, and achieves the effect that the inner layer and the outer layer of a thick non-woven material after dyeing are uniform.

Description

technical field [0001] The present invention relates to the field of paint pad dyeing, and more specifically relates to a finishing solution and a preparation method after paint pad dyeing, which has a very outstanding effect on pad dyeing of textile, non-woven, composite materials, etc., especially for a thickness of 1.0mm above products. Background technique [0002] The paint pad dyeing process is short, the equipment is simple, the operation is convenient, the color spectrum is uniform, the color is bright, the quality is stable, the authenticity rate is high, the reproducibility is good, labor saving, energy saving and water saving are generally favored by the world. In the United States, about 80% of the color cloth is produced by this process, but in my country, only about 20%. The majority of workers in dyeing and finishing and printing and dyeing auxiliaries are working together to research and develop, so that the coating pad dyeing process will continue to improve...
