Abstract

The invention discloses a production method of a warp knitting raising interior decorative material of an automobile, comprising the steps of selecting raw material, performing warping, weaving, dyeing and pre-shaping; napping, performing shaping and bonding; bonding a napped fabric and an automobile interior decorative plate by glue. The fabric has size stability, elasticity, softness and wearing resistance; the raising fabric has light weight and then satisfies light requirement of the whole vehicle; the raising surface of the raising warp knitting fabric replaces a non-woven cloth or a sponge in the automobile interior composite fabric, thus, the compounding process of the warp knitting fabric or the non-woven cloth or sponge is saved, the whole process flow for processing the automobile interior decorative material is simplified, the energy consumption is reduced, the harmful gas volatilization during the process is reduced, the molded fabric bonded with the automobile interior decorative plate does not wrinkle, the problems that the automobile interior decorative composite fabric is easy to wrinkle during the bonding and the fabric and the sponge or the non-woven cloth are easy to separate during the usage for a long period are solved; the warp knitting raising interior decorative material is suitable for ceilings, skylight interior decorative plates and upper cover plates of a trunk of a passenger car.

Description

technical field [0001] The invention relates to a production method of an automobile interior material, in particular to a production method of a warp-knitted pile automobile interior material. Background technique [0002] Textiles are comfortable, breathable, functional, decorative and environmentally friendly, and have been widely used in car seats, carpets, roof trims, door trims, curtains, safety belts, backings, tarpaulins , airbags, etc. Automotive textiles are mainly organic fabrics, knitted fabrics, non-woven fabrics and fiber composite materials. Among them, the warp-knitted fabrics in knitted fabrics have good extensibility and elasticity, soft and comfortable hand feeling, stable structure, and low dedispersibility. Processing can endow the fabric with wear-resistant, flame-retardant, anti-ultraviolet and other functions that meet the standards of automotive interiors. At the same time, the elongation in all directions can meet the needs of various surface struc...
