Production technology of cold-resistant breathable imitated leather coated fabric with concave-convex particles

Abstract

The invention discloses a production technology of a cold-resistant breathable imitated leather coated fabric with concave-convex particles. The production technology comprises the following steps: (1) coating technology: preparing surface layer slurry from the following components by weight: 100 kilograms of polyurethane resin, 30 to 40 kilograms of DMF solvent, 30 to 40 kilograms of diluent, 2 to 3 kilograms of antiseptic, 0.3 to 0.5 kilogram of organic silicon aid, and 3 to 7 kilograms of pigment, preparing bottom layer slurry from the following components by weight: 100 kilograms of polyurethane resin, 4 to 6 kilograms of DMF solvent, and 4 to 6 kilograms of diluent, painting the bottom layer slurry on woven suede, drying, cooling, then painting surface layer slurry on the bottom layer, preheating, pasting cloth, drying again, cooling, peeling, and examining; (2) surface printing technology: reeling the coated cloth obtained in the step (1), performing first edition printing, drying, performing second edition printing, placing on a needle bed, drying through baking, cooling, reeling, and examining; (3) combination technology: combining the coated woven suede and leather covered basic cloth to produce sofa cloth. The technology can save slurry. The obtain product is light and thin, is similar to real leather, and has the advantages of breathability, cold resistant property, antibacterial function, hydrolysis resistant performance, and environment-friendliness.

Description

technical field [0001] The invention relates to a production process of a coated fabric, in particular to a production process of a concave-convex particle type cold-resistant high-transparency imitation leather coated fabric. Background technique [0002] Coated fabric is a kind of fabric treated by special process. According to the different coating materials, there are three types of fabrics: PVC coating, PU coating and semi-PU coating. From the style of coating products, there are artificial leather coatings. Layered fabrics, glossy coated fabrics, transparent coated fabrics, etc. Among them, imitation leather coated fabrics are popular among young people because of their strong sense of fashion. Imitation leather coating surface is a general term for man-made materials such as polyurethane (PU) and polyvinyl chloride (PVC). It can be processed according to the requirements of different strength, wear resistance, cold resistance, color, gloss, pattern, etc. However, th...

Problems solved by technology

However, this kind of imitation leather products are often based on woven artificial leather. Its feel and elasticity are difficult to achieve the effect of genuine leather, and its hygiene and physical and chemical properties are far inferior to natural leather; Stiff, resulting in poor cold resistance and breathability of the coating, so it is not ideal for faux leather coated fabrics
