Manufacturing method for microfiber suedette for top-grade automobile interior trim

Abstract

The invention discloses a manufacturing method for microfiber suedette for top-grade automobile interior trim. The method includes the steps of material selection, fuzzing, processing before dyeing, dyeing, sanding and dipping in insolation-resistant auxiliaries, so that a finished product is obtained. Due to the fact that water-based PU resin which is high in insolation and extremely good in environmental protection is adopted, the insolation-resistant effect of the resin is improved, no organic solvent is contained, the microfiber suedette can be prevented from emitting poisonous gas, and the process is simple, concise, easy to operate and environmentally friendly and saves more energy. Through dipping of the insolation-resistant auxiliaries in the later period, the fiber insolation-resistant fastness is improved by three levels or more, the fiber insolation-resistant fastness of the finished microfiber suedette reaches the fifth level to the sixth level, and the requirement for automobile interior trim is met. Through continuous grinding of base cloth and a semi-finished product, the cloth cover is more fine and smooth, the writing effect is obvious, and the chamois leather feeling is higher. Large-scale production of the microfiber suedette can be achieved, and the price of the microfiber suedette is 50% lower than that of foreign products. The microfiber suedette for interior trim is low in cost, free of emission of poisonous gas, resistant to insolation, simple in manufacturing process, low in cost and capable of being produced on a large scale.

Description

technical field

[0001] The invention relates to the technical field of artificial leather, in particular to a method for manufacturing superfine fiber imitation suede for high-grade automobile interior decoration. Background technique

[0002] With the development of the automobile industry and people's pursuit of high-end luxury car interiors, many high-end luxury cars will use imitation suede interior fabrics, such as car roofs, steering wheel covers, and car seats, to make the interior of the car It looks graceful and luxurious. However, this kind of suede-like fabric has high technical content and is monopolized by very few companies in Japan and Italy. Because this kind of fabric is not only fine and uniform in suede, but also has excellent light fastness in physical properties. Although some domestic factories produce products with similar appearance, this kind of car decoration is easy to change color in harsh environments such as high temperature and cold. , causin...
