Description
Technical field
The present invention relates to a kind of production technology of coating fabric, the production technology of the high artificial leather coating fabric thoroughly that resists cold more specifically to a kind of concavo-convex granular pattern.
Background technology
Coating fabric is a kind of fabric through special process process, according to the difference of coating material, there are PVC coating, PU coating and half PU coating three major types fabric, come point have artificial leather coating fabric, reflecting feel coating fabric, clear coat fabric etc. from the style of coating product, wherein artificial leather coating fabric is subject to by force liking of young people because of its stylishness.Leather like coating face is the general name of the artificial material such as polyurethane (PU) and polyvinyl chloride (PVC), it is weaving on fabricbase or non-woven fabricbase, processed by the coating such as PU and PVC of various different formulations, can require process according to varying strength, abrasion resistance, cold-resistant degree and color, gloss, floral designs etc.But this kind of simulated leather product is the artificial leather of base often with woven, and its feel and elasticity are difficult to the effect reaching corium, and wholesomeness and physicochemical property are also far away less than natural leather; In addition, because PVC easily hardens at low temperatures, cause the cold resistance of coating and gas permeability poor, be not therefore desirable artificial leather coating fabric.
As, application number is disclose a kind of leather fabric in the invention of 201110335337.4, comprises Ji Bu and coat side, and is provided with penetrable coating layer between described Ji Bu and described coat side, and described Ji Bu is knit fabric, and described coat side is PVC.
And for example, application number is the processing method disclosing a kind of suede nap epithelial membrane coating in the patent of invention of 201310592132.3, and (1) bottom gluing is prepared: polyurethane resin 100 parts, polyurethane thickener 0.5 ~ 1, melamine crosslinkers 0.5 ~ 2, foam stabiliser 4 ~ 10, blowing agent 1 ~ 3 part stirred and carry out foam volume and increase to 1-3 doubly; (2) surface layer gluing preparation: 100 parts, cold-resistant unglazed coating glue, amino modified polysiloxane 5 ~ 10 parts, melamine crosslinkers 0.5 ~ 2 part, mill base are stirred; (3) the direct coating of dry method is adopted; Bottom gluing dry weightening finish 5-8g/m
2, then use calender calendering, surface layer gluing dry weightening finish 7-10g/m
2.
Therefore, develop a kind of feel and the elasticity with corium, having again good gas permeability, cold resistance and other functional coating fabrics has very great meaning and value simultaneously.
