Problems solved by technology

However, in the prior art, the research on the stability of printing pastes in a vacuum environment is still lacking, and the technical solutions specially used to improve the heat-resistant vacuum fastness of colored textiles are basically blank, and the thermal vacuum environment is more stable than the high-heat environment. Harsh, so the stability of the color paste is more demanding

Embodiment 1-3 and comparative example 4-6

[0042] A paint printing process with high heat and vacuum fastness, including the printing treatment of paint printing color paste and the padding treatment process of water-based polyurethane emulsion (particle size is 200-500nm), and the prepared paint printing color paste is about to be prepared for blending polyester-cotton fabrics Printing, and then padding a layer of water-based polyurethane coating film, post-curing and drying. Among them, the pigment printing paste includes by mass percentage:

[0043] 1~10% pigment;

[0044] 1~10% wool fiber powder; the particle size of wool fiber powder is 35μm (including discontinuous medulla layer);

[0045] 2~3% PTF paste;

[0046] 0.5~1% coupling agent KH-560;

[0047] 10~20% adhesive UDT;

[0048] 0.5~1% cross-linking agent AF6900;

[0049] The remainder is distilled water.

[0050] The configuration method is: S1. Add 1%-10% pigment, 1%-10% wool fiber powder and 0.5%-1% silane coupling agent into distilled water, and stir...

Embodiment 4

[0057] A pigment printing process with high thermal vacuum fastness, compared with Example 2, the difference is that the wool fiber powder is immersed in 5% concentration of ammonia water for 20 minutes. Others are substantially the same as those in Embodiment 2, and are not repeated here.

Abstract

The invention provides a paint printing process with high thermal vacuum fastness, which includes the printing treatment of the paint printing color paste and the padding treatment of the water-based polyurethane emulsion. The pigment printing paste includes by mass percentage: 1%-10% pigment, 1%-10% wool fiber powder, 0.5%-1% silane coupling agent KH-560, 10%-20% bonding agent agent, 2% to 3% of thickener and 0.5% to 1% of crosslinking agent, and the balance is solvent. By adding wool fiber powder with special structure and coupling agent into the color paste, and padding a layer of water-based polyurethane coating film after printing, the invention significantly improves the high-heat vacuum fastness of pigment molecules and solves the problem of colored pigments. The color fastness of pigment sublimation and migration caused by thermal vacuum suction of pigment molecules in textiles under high vacuum and high temperature environment conditions.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a paint printing process with high thermal vacuum fastness. Background technique [0002] Pigment printing is a printing method that adheres the paint to the printed fibrous material by means of the action of the binder in the printing paste. Because of its simple process and short production process, especially after pigment printing, it generally does not need to be washed, which saves a lot of water and reduces the emission of pollutants. Industrial welcome. [0003] The composition of pigment printing paste generally contains main components such as paint, adhesive, thickener, other auxiliary agents and water. Among them, the coating provides coloring components in the pigment printing paste, which is a slurry made of organic (or inorganic) pigments and corresponding dispersing agents, wetting agents, colloidal protective agents, preservatives and other auxiliar...
