Technical Field

The invention relates to a fabric coating treatment process, in particular to an ultra-bright tear-resistant silica gel coating treatment process for cotton fabrics.

Background

The existing coating process for cotton fabrics is generally to coil dyed cloth/semi-bleached after preshrinking, and then coat and scald a film to obtain a finished product, wherein the adopted coat is generally solvent silica gel, but the adopted mode can not meet the requirement of high environmental protection, while the adopted silica gel coat with environmental protection performance has poor film forming property, can not embody excellent super-bright performance, and the product quality needs to be improved. Therefore, the existing cotton fabric coating cannot meet the high environmental protection requirement of the cotton coating under the condition of better film-forming property and super-bright property.

Disclosure of Invention

The invention aims to provide a treatment process of an ultra-bright tear-resistant silica gel coating of a cotton fabric. The invention has the characteristics of high environmental protection performance, good film forming property and super-bright property.

The technical scheme of the invention is as follows: the super-bright tear-resistant silica gel coating treatment process of the cotton fabric comprises the following operation steps of:

a. pre-shrinking the dyed cloth or the semi-bleaching cloth to obtain a product A;

b. backing and rolling the product A to obtain a product B;

c. and coating the front surface of the product B with a silica gel coating and then coating a polymer coating to obtain a finished product.

In the ultra-bright tear-resistant silica gel coating treatment process for cotton fabrics, the step a is specifically to pre-shrink the dyed cloth or semi-bleached cloth by 3-4% to obtain a product A.

In the treatment process of the ultra-bright tear-resistant silica gel coating for the cotton fabric, in the step b, the reverse priming coating comprises the following raw materials in parts by weight: 10-20 parts of base glue, 80-90 parts of water and 2-5 parts of thickening agent.

In the ultra-bright tear-resistant silica gel coating treatment process for cotton fabrics, the base glue is polyurethane coating glue, and the polyurethane coating glue contains 30% of high-molecular silicone oil.

In the treatment process of the ultra-bright tear-resistant silica gel coating of the cotton fabric, in the step b, the drying temperature for back priming is 150-.

In the ultra-bright tear-resistant silica gel coating treatment process for cotton fabrics, in the step b, the thickness of the reverse priming coating is 0.1 mm.

In the treatment process of the ultra-bright tear-resistant silica gel coating for the cotton fabric, in the step c, the coating of the silica gel coating comprises the following raw materials in parts by weight: 60-70 parts of silica gel, 30-40 parts of water and 2-5 parts of thickening agent.

In the step c, the speed of a coating machine of the silica gel coating is 15-50m/min, the coating pressure is 0.8-1.2kg, and the thickness of the silica gel coating is 0.2-0.3 mm.

In the step c, the drying temperature of the silica gel coating is 150-.

Compared with the prior art, the invention controls the amount of the primer and the face adhesive and related process parameters through multilayer gluing, so that the fabric is uniform and flat in film forming, stronger in film feeling, good in anti-sticking property, stability and hand feeling adjusting function, and better in film forming property, and the fabric is endowed with dry and smooth hand feeling and has a certain increment effect; the adopted primer is matched with the high-molecular coating, contains high-molecular silicone oil with a self-film forming function, has the characteristic of ultra-bright light, and also meets the requirement of high environmental protection; the silica gel coating is highly silica gel smooth and comfortable and has a membrane feeling, so that the tearing strength of the fabric can be improved, and the fabric has a good tearing resistance effect. The whole silica gel coating treatment process is simple to operate, convenient to control and low in cost. Therefore, the invention has the characteristics of high environmental protection performance, good film forming property and super-bright property.
