Problems solved by technology

This method makes the surface of the water curtain-like PE film just out of the die mouth bright and smooth, and falls into the two layers of non-woven fabrics and is extruded and bonded; the problem is that the formed middle PE layer is very dense, uniform, smooth, and cools. After being hard, the two layers of non-woven fabrics are completely separated, and there is no air permeability between the two layers of non-woven fabrics

Abstract

The invention relates to a processing technology of a non-woven fabric composite material for automotive interior. The method is characterized by comprising the following steps: (1) evenly spraying polyethylene powder particles on a non-woven fabric bottom layer through a powder spraying device, wherein machine speed for the non-woven fabric bottom layer is 1.8-2.5m / min, vibration amplitude of a vibrating screen is 2-5mm, and the number of meshes of the vibrating screen is 10-20 meshes; (2) placing the non-woven fabric bottom layer with polyethylene powder particles in a drying room, setting temperature in the drying room to be 150-190 DEG C, wherein inside of the drying room is divided into three heating regions according to the temperature from the fabric feeding direction to the fabric discharging direction, the temperature of the three regions rises gradually, and the distance between an electric heating quartz tube at upper part of the drying room and the non-woven fabric bottom layer is 60-80mm; and (3) compositing the non-woven fabric bottom layer output from a fabric discharge port of the drying room and a non-woven fabric surface layer together on a cooling compression roller to obtain the composite non-woven fabric; and after outputting the composite non-woven fabric by a conveying roller, cutting and winding the composite non-woven fabric to obtain the non-woven fabric composite material for automotive interior. With the processing technology, cost can be reduced, and energy consumption can be lowered.

Description

technical field [0001] The invention relates to a processing technology of automobile non-woven carpet, in particular to a processing technology of non-woven composite material for automobile interior decoration. Background technique [0002] The existing two-layer and three-layer structure carpet compound process processing methods of non-woven fabrics and sheets include the following two types: [0003] One is a composite material with a two-layer structure; the method is to superimpose two layers (surface layer and bottom layer) of carpet and then pass through a needle punching machine process, using needles to link the two layers of non-woven fabric fibers together to make the two layers non-woven Spinning and compounding together. The specific technological process is: surface layer production process: cotton blending → carding → net laying → needle punching → forming the surface layer; bottom layer production process: cotton blending → carding → web laying → acupunctu...
