Production process of automobile ceiling cloth with low VOC value

Abstract

The invention relates to the technical field of textile, in particular to a production process of an automobile ceiling cloth with low VOC value. The method comprises the steps of 1, materials preparation, specifically, fabrics, sponges and base fabrics with appropriate specifications are selected; 2, flame compounding, specifically, the fabrics, the sponges and the base fabrics are compounded together through a flame compounding device to obtain composite cloth of a three-layer structure; 3, tension adjusting, specifically, tension adjustment is carried out on the composite cloth through a tension adjusting device; 4, pretreatment, specifically, the composite cloth treated in the third step is subjected to air cooling until the temperature of the composite cloth is kept at 25-30 DEG; 5, ozone treatment, specifically, the composite cloth treated in the fourth step is introduced into an ozone bin, ozone concentration in the ozone bin is 20-30 ppm, and humidity in the ozone bin is no less than 95%; and 6, winding, specifically, a winding device is adopted for winding the composite cloth treated in the fifth step to obtain a finished product. The VOC value of the automobile ceiling cloth is effectively reduced, and the safety of materials is improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a production process of an automobile roof cloth with low VOC value. Background technique [0002] The automotive interior fabric is usually a three-layer composite fabric of polyester fabric + polyurethane sponge + polyester base fabric. The composite fabric is melted by flame grilling to melt the surface of the sponge, and the fabric and base fabric are pasted on the sponge. The chemical properties of the polyester fabric itself are very stable. High temperature resistance, corrosion resistance, and not easy to decompose, so the odor and VOC of automotive interior fabrics mainly come from polyurethane sponge, which consists of small molecular benzene hydrocarbons and aldehydes and ketones, with high VOC value and large amount of harmful gas release. It is very harmful. Contents of the invention [0003] The technical problem to be solved by the present invention is to provi...
