Production process of automobile roof cloth with low VOC (volatile organic compound) value

Abstract

The invention discloses a production process of automobile roof cloth with a low VOC value. The production process comprises the following steps: S1, selecting fabric, sponge and base cloth with proper specifications; S2, a front cleaning mechanism is used for cleaning the fabric, the sponge and the base cloth selected in the S1; S3, preheating and drying the fabric, the sponge and the base cloth obtained in the step S2 by using a preheating and drying mechanism; S4, synchronously compounding and bonding the shell fabric and the base fabric obtained in the S3 to the two surfaces of the sponge respectively by adopting a flame compounding mechanism; S5, carrying out ozone oxidation treatment on the composite cloth obtained in the step S4 by utilizing ozone; S6, preheating and drying the composite cloth obtained in the step S5 by using a cooling and drying mechanism; and S7, subjecting the composite cloth obtained in the step S5 to cleaning by using a rear cleaning mechanism. Dust and impurity removal treatment is conducted on the raw materials before flame compounding treatment, the adverse effect of dust and impurities on the quality of the composite cloth in the flame compounding process can be avoided, and then the production quality of the composite cloth is improved.

Description

technical field [0001] The invention relates to the technical field of production of automobile ceiling fabrics, in particular to a production process of automobile ceiling fabrics 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, and its components are small molecule benzene hydrocarbons and aldehydes and ketones. However, most of the existing low-VOC car roof fabric production processes use flame compounding to combine polyester fabric + polyurethane sponge + pol...

AI Technical Summary

Problems solved by technology

However, most of the existing low-VOC car roof fabric production processes use flame compounding to combine polyester fabric + polyurethane sponge + polyester base fabric with three layers of composite fabric, and then use ozone reaction to reduce the VOC value of the composite fabric. It is easy to stick dust and debris, which affects the production quality of composite fabrics during flame lamination
