Abstract

The invention relates to a suede fabric pasting technology, and belongs to the technical field of a suede fabric production technology. The suede fabric pasting technology comprises the following steps of 1, coating a first poly urethane (PU) layer on a release paper, 2, enabling the release paper with the first PU layer to pass orderly through baking ovens respectively having preset temperaturesof 110+ / -5 DEG C, 115+ / -5 DEG C and 120+ / -5 DEG C for drying, 3, coating a second PU layer on the first PU layer, 4, enabling the release paper with the first PU layer and the second PU layer to passorderly through baking ovens respectively having preset temperatures of 80+ / -5 DEG C and 80+ / -5 DEG C for drying, 5, pasting a suede fabric base cloth on the second PU layer, 6, enabling the release paper with the first PU layer, the second PU layer and the suede fabric base cloth to pass orderly through baking ovens respectively having preset temperatures of 135+ / -5 DEG C, 135+ / -5 DEG C, 140+ / -5DEG C, 140+ / -5 DEG C and 135+ / -5 DEG C for drying, and 7, peeling the release paper to obtain a finished product. A suede fabric product prepared by the suede fabric pasting technology has the advantages of good handle, good permeability, good wear resistance and good cold resistance.

Description

technical field [0001] The invention relates to a suede pasting process, which belongs to the technical field of suede production technology. Background technique [0002] Suede fabric has many properties that are not inferior to natural suede, and many properties are even better than natural suede, such as its fabric has soft wool, waxy, good drapability, and light and thin texture. Suede fabric is suitable for bags, shoes (lining, fabrics are suitable), clothing, car interiors, cleaning cloth (eye cloth), leather base cloth, high-end packaging boxes, lighting materials, etc. But along with the raising of living standard, the quality of existing suede fabric can't satisfy people's demand more and more, such as breathability, abrasion resistance etc. Contents of the invention [0003] In order to solve the above problems, the present invention provides a suede patch process with good air permeability and high wear resistance. [0004] To achieve the above object, the tec...
