Problems solved by technology

[0002] With the development of the automobile industry and the improvement of people's awareness of environmental protection of automobiles, the technology of environmental protection and waste recycling is particularly important, and the current car carpets are mostly non-woven fabrics coated with acrylic glue on the back and PE; for shock absorption, The carpet is coated with foamed PVC on the PE surface, and this process produces a large amount of exhaust gas and pungent odor. After the carpet is scrapped, the product cannot be degraded, and the cost is high, which is not conducive to the development of China's automobiles.

Embodiment 1

[0015] Example 1: A kind of waste cotton composite car carpet

[0016] Fabric layer preparation: take polyester fiber to open and mix uniformly; then transfer the polyester fiber to the carding machine through the cotton storage box to form a fiber web; send the fiber web to the netting machine and lay it into multiple layers The multi-layer fiber web is transported to the needle punching machine for needle punching to form a fabric layer with a needle punch density of 35 needles / cm²; the needle punch depth of the needle punch is 3mm and the speed 3m / min; then the fabric layer is transported to the raising machine for raising, the raised pile height is 5.6mm, and the raised pile density is 450 needles / square centimeter;

[0017] The preparation of the bottom material layer: take the polypropylene fiber, polyester fiber and waste cotton with a weight percentage of 10:35:55 ​​to open and mix them uniformly; send them to the carding machine through the cotton storage box to form a fib...

Abstract

The invention relates to a waste-cotton composite automotive carpet comprising a fabric layer, a backing layer and an adhesive layer of the fabric layer and the backing layer. The waste-cotton composite automotive carpet is characterized in that the fabric layer is made of polyester; the adhesive layer is formed by melting polyethylene at a high temperature; the backing layer is formed by mixing mekralon, polyester and waste cotton. The invention adopts a three-layer structure so that the surface style of the product can be kept, and the carpet has shockproof action due to the relatively loose backing layer which forms a porous structure by combing and prickling polypropylene, waste cotton and mixed polyester fiber to take the soundproofing and thermal-insulating effects; polypropylene added to the backing layer is melted at a high temperature to satisfy the molding requirement of the carpet and replace a traditional adhesive (such as acrylic acid); the polyethylene between the fabric layer and the backing layer is melted at a high temperature to take the adhesive, waterproof and crease-resist effects; the backing layer adopts recycled leftovers so as to recycle the original leftovers, lessen the environmental pollution and decrease the cost.

Description

Technical field [0001] The invention relates to a new material automobile carpet, in particular to a waste cotton composite automobile carpet. Background technique [0002] With the development of the automobile industry, people's awareness of environmental protection of automobiles has increased. The technology of environmental protection and waste recycling has become particularly important. The current automobile carpets are mostly non-woven fabric back coated with acrylic glue and PE; in order to reduce shocks, Carpets are coated with foamed PVC on the PE surface, and this process produces a lot of exhaust gas and has a pungent odor. After the carpet is scrapped, this product cannot be degraded, and this cost is high, which is not conducive to the development of Chinese automobiles. Summary of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a waste-cotton composite automobile carpet with low pollution and...
