Problems solved by technology

[0002] At present, there are many types of advertising cloth products in the market, and the application range is wide, and in order to meet customer needs, the performance requirements for advertising cloth are getting higher and higher; the following problems exist in the actual application of advertising cloth in the prior art: (1) the existing The coating process of the waterproof and oil-repellent coating of advertising cloth products is mainly in the way of dipping and rolling. After being cured in an oven at 160-180°C, the gray cloth is waterproof and oil-proof on both sides, and the water drops will appear on both sides of the gray cloth, and the gray cloth will be water-repellent as a whole, which cannot meet the printing requirements of different performance inks; (2) the existing Although some advertising fabrics can meet the printing needs of inks with different performances, because some ink-absorbing coatings cannot be coated on the surface of waterproof gray fabrics, due to the limitation of processing technology, they can only give up waterproofing, and the products made will become hard

Embodiment 1

[0020] A gray cloth treatment process comprises the following steps:

[0021] (1) Configuration of whitening waterproof coating: 500 parts of water, 10 parts of water repellent (octacarbon fluorine water and oil repellent), 1.5 parts of fluorescent whitening agent (bisstyrene derivative) and PTF in parts by weight Mix 5 parts of thickener, adjust the pH to 7.2, and obtain a whitening waterproof coating with a viscosity of 20000cps;

[0022] (2) Coating coating: After the cleaned gray cloth is released from the unwinding device, it enters the coating head device through the control of multiple guide rollers and tension rollers (the air pressure of the tension roller is 0.3MPa). Cloth wetness is the amount of 20gsm with 3mm shoe type knife (the angle of shoe type knife is 90 ℃, and knife distance is 0.5mm) the whitening waterproof coating of step (1) is evenly coated on the surface of gray cloth, coating speed is 40m / min, after drying and curing treatment, and then controlled b...

Embodiment 2

[0025] A gray cloth treatment process comprises the following steps:

[0026] (1) Configuration of whitening waterproof coating: 600 parts of water, 20 parts of water repellent (six carbon fluorine-based water and oil repellent), 2 parts of fluorescent whitening agent (bisstyrene derivative) and PTF in parts by weight Mix 6 parts of thickener, adjust the pH to 7.5, and obtain a whitening waterproof coating with a viscosity of 28000 cps;

[0027] (2) Coating coating: After the cleaned gray cloth is released from the unwinding device, it enters the coating head device through the control of multiple guide rollers and air tension rollers (the air pressure of the air tension roller is 0.5MPa). Use a 3mm shoe-shaped knife (the angle of the shoe-shaped knife is 92°C, and the knife distance is 0.6mm) to apply the whitening and waterproof coating in step (1) evenly on the surface of the gray cloth according to the amount of coating wetness of 30gsm. The speed is 45m / min. After drying...

Embodiment 3

[0030] A gray cloth treatment process comprises the following steps:

[0031] (1) Configuration of whitening waterproof coating: 800 parts of water, waterproofing agent (C 6 30 parts of fluorine-free waterproofing agent), 3.5 parts of fluorescent whitening agent (distyrene derivatives) and 8 parts of PTF thickener are mixed evenly, adjust pH7.8, obtain the whitening waterproof coating that viscosity is 35000cps;

[0032] (2) Coating coating: After the cleaned gray cloth is released from the unwinding device, it enters the coating head device through the control of multiple guide rollers and air tension rollers (the air pressure of the air tension roller is 0.7MPa). According to the amount that the coating moisture is 40gsm, the whitening and waterproof coating in step (1) is evenly coated on the surface of the gray cloth with a 4mm shoe knife (the angle of the shoe knife is 90°C, and the knife distance is 0.8mm). The machine speed is 48m / min. After drying and curing treatment...

Abstract

The invention relates to a coating process, in particular to a grey cloth treatment process. The process comprises steps as follows: (1) preparation of a whitening and waterproof coating: water, a waterproof agent, a fluorescent whitening agent and a thickener are mixed uniformly in parts by weight, and the pH is regulated; (2) application of the coating: the cleaned grey cloth is released by an unwinding device and enters a cloth coating device under the control of multiple guide rollers and tension rollers, the whitening and waterproof coating in the step (1) is uniformly applied to the surface of the grey cloth with a flat knife after pouring, and the grey cloth is subjected to drying and curing treatment, then enters a winding device under the control of the multiple guide rollers andtension rollers and finally is wound by the winding device. The product obtained with the treatment process has the single-side waterproof performance and can meet the printing demands of ink with different properties, and the obtained product is soft.
