Non-woven fabric layer of automobile interior trim and manufacturing method thereof

Abstract

The invention discloses a non-woven fabric layer of an automobile interior trim, which is compounded by needled non-woven fabric and spun-bonded non-woven fabric of which the transverse strength is lower than the longitudinal strength. The strength difference of the needled non-woven fabric is balanced by the spun-bonded non-woven fabric of which the transverse strength is lower than the longitudinal strength so that the longitudinal and transverse strengths of the compound fabric layer are balanced; and because the surface of the spun-bonded non-woven fabric has superior finish, the compoundfabric compounded by the spun-bonded non-woven fabric and the needled non-woven fabric is easy to strip when the compound fabric is processed into the automobile interior trim. The non-woven fabric layer of the automobile interior trim can be used in die pressing forming compound pieces of automobile seats, ceilings, rear cover compartments, automobile doors and the like.

Description

technical field [0001] The invention belongs to the textile industry, and in particular relates to a non-woven fabric layer of an automobile interior trim and a manufacturing method thereof. Background technique [0002] European vehicle regulations require that from 2015 onwards, at least 95 percent of the total weight of all car components must be recyclable. This means that natural cellulose fibers, single-component polymer materials will be fully applied. [0003] Automakers and nonwovens manufacturers are continually experimenting with existing and new fibers to develop their use in the manufacture of body and interior materials in order to reduce vehicle costs and fuel consumption. Nonwovens are used more and more in the process of improving the design of cars and their various components. The automotive industry consumes approximately 1.28 million tons of nonwovens per year. [0004] More than 40 parts in the car require the use of nonwovens, from cabin air filters...

AI Technical Summary

Problems solved by technology

[0005] Existing automotive interior parts are generally molded from non-woven fabric layers and other non-woven materials. Automotive interior parts require that the vertical and horizontal strength of the non-woven fabric layer have little difference. The woven fabric layer generally adopts needle-punched fabric. The transverse strength of the needle-punched fabric is greater than the longitudinal strength, resulting in uneven vertical and transverse strength of the non-woven fabric layer; and the surface of the needle-punched fabric has almost no smoothness. During the process of trimming, high temperature molding is required, which will cause the fibers to adhere to the mold, making it difficult to demould
