Problems solved by technology

[0005] However, there are certain problems in the existing transfer film-forming method: when the calender roller is rolling the base fabric and the transfer paper, the base fabric is prone to wrinkle, and one of the reasons for this phenomenon is that the calender roller The surface of the roller is not smooth enough, especially when dealing with some fabrics that are easy to depilate. The roughness of the surface of the pressure roller, the wrinkling phenomenon is more obvious

Embodiment 1

[0035] Fabric coating process, comprising the following steps:

[0036] Step 1, preparation of coating agent ingredients: weigh 100kg of water, 100kg of polysiloxane, 10kg of polyurethane, 5kg of polyvinyl acetate, 1kg of accelerator, and 5kg of mica flakes by mass.

[0037] Step 2, preparation of coating agent: Grind mica sheet into mica powder, and filter with 150 mesh filter screen; Place the water, polysiloxane, polyurethane, polyvinyl acetate and accelerator in step 1 in the reaction kettle, and After stirring for 5 minutes under the action of a spiral stirring rod, add mica powder and continue stirring for 15 minutes to obtain a coating agent.

[0038] Step 3, transfer paper coating: use a floating knife to evenly coat the coating agent in step 2 on the upper surface of the transfer paper.

[0039] Step 4, the base cloth is leveled: as figure 1 As shown, the base cloth and the transfer paper in step 3 are conveyed by the base cloth feeding roller and the transfer paper...

Embodiment 2

[0048] The difference between this embodiment and embodiment 1 is:

[0049] In step 1, preparation of coating agent ingredients: weighing 100kg of water, 150kg of polysiloxane, 15kg of polyurethane, 10kg of polyvinyl acetate, 5kg of accelerator, and 8kg of mica flakes by mass.

[0050] In step 2, preparation of coating agent: Grinding mica flakes into mica powder, and filtering with a 200-mesh filter screen; placing water, polysiloxane, polyurethane, polyvinyl acetate and accelerator in step 1 in a reaction kettle, and After stirring for 8 minutes under the action of a spiral stirring rod, add mica powder and continue stirring for 20 minutes to obtain a coating agent.

[0051] In step five, the pressing force of the upper roller and the lower roller to the base cloth is 12N.

[0052] The drying temperature in step seven is 70°C.

Abstract

The invention belongs to a technique for coating the surface of an object with a liquid or other fluids, and concretely relates to a fabric coating technology. The technology comprises the following steps: 1, preparation of coating agent ingredients; 2, preparation of a coating agent; 3, coating of transfer paper; 4, flattening of a base fabric; 5, transfer of the obtained coating layer; 6, cleaning of an upper roller; 7, drying; and 8, rolling. The base fabric is effectively prevented from crumpling in the coating process.

Description

technical field [0001] The invention belongs to a technology for coating liquid or other fluids on the surface of objects, and in particular relates to a fabric coating process. Background technique [0002] Coating, also known as coating, refers to the finishing and processing technology of uniformly coating one or more layers of polymer compounds on the surface of fabrics and forming one or more layers of films on the surface of fabrics through bonding. Its purpose is to improve the feel, appearance and style of the fabric, and add many new functions to the fabric, such as windproof, waterproof, moisture-permeable, down-proof, flame-retardant, shading and other functions. [0003] The traditional coating method is mostly direct coating, that is, the coating agent is diluted with solvent or water according to the required concentration, and the necessary medicament and colorant are added to make a coating slurry, which is evenly coated on the base cloth with a spreader , a...
