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
The present invention relates to a kind of novel material automobile carpet, especially a kind of waste-cotton composite automotive carpet.
Background technology
Along with the development of auto-domain, people are to the raising of the environmental consciousness of automobile, and it is particularly important that the technology of environmental protection and refuse reclamation shows, and mostly used car carpeting is that the nonwoven fabrics back of the body is coated with acrylic acid glue and adds PE; For damping, carpet is coated foaming PVC at the PE face, and this course of processing produces a large amount of waste gas, has pungent smell to produce, and carpet is scrapped this product of back and can't be degraded, and this cost is higher, is unfavorable for the Chinese automobile development.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of pollution, waste-cotton composite automotive carpet that cost is low of reducing is provided.
According to technical scheme provided by the invention; Said waste-cotton composite automotive carpet; The adhesive linkage that comprises precoat, initial bed, the bonding plane bed of material and initial bed; Characteristic is: said precoat is processed by poly-ester fibres, and said adhesive linkage is processed by the poly-vinyl high-temperature fusion, and said initial bed is mixed and made into by mekralon, poly-ester fibres and waste cotton.
The weight ratio of mekralon, poly-ester fibres and waste cotton is 10～40: 20～50 in the said initial bed: 25～55.
The needling density of said precoat is 35～105 pins/sq cm.
The needling density of the initial bed of stating is 85～235 pins/sq cm.
Make the method for waste-cotton composite automotive carpet, comprise the steps:
(1), with the poly-ester fibres shredding, mix; Be transported to the carding machine combing through cotton storage tank and form fleece; This fleece is flowed to the lapping machine, and laying becomes the fleece of multilayer; Fleece with multilayer is transported to needing machine again, carries out acupuncture, processes precoat; The depth of needling of described needing machine is that 3～9mm, speed are 3～9m/min; Then precoat is transported to napping machine, carries out napping, the suede height of said napping is 5.6～7.6mm, and the suede of napping is close to be 450～750 pins/sq cm;
(2) mekralon, poly-ester fibres and waste cotton are carried out shredding in the preset weight ratio, mix; Be transported to carding machine through cotton storage tank and carry out combing formation fleece; This fleece is flowed to the lapping machine, and laying becomes the fleece of multilayer; Fleece with multilayer is transported to needing machine again, carries out acupuncture, processes initial bed; The depth of needling of described needing machine is that 3.5～10.5mm, speed are 2～6m/min;
(3) with the poly-vinyl high-temperature fusion, the initial bed in precoat in the step (1) and the step (2) is bonded together on pouring film machine, said melt temperature is 230～330 ℃.
Advantage of the present invention is: 1. adopt three-decker, can keep the surperficial style of product, simultaneously because of the loose relatively institute of bottom so that carpet has antihunt action; 2. bottom forms pory structure with polypropylene, waste cotton and polyester shredding hair composite fibre later on through combing, acupuncture, plays sound insulation, heat-insulating effect, replaces traditional foaming PVC, so be a environment-friendly type carpet; 3. add polypropylene in the bottom and satisfy the moulding requirement of carpet, replace traditional glue (like acrylic acid) to play the moulding effect through hi-heat fusing; 4. in the middle of surface layer and the bottom with the adhesive effect of poly-vinyl through rising after the high-temperature fusion, play waterproof, wrinkle resistant effect; 5. bottom reuse rim charge makes company's rim charge of scrapping originally get feed back, reduces environmental pollution, simultaneously with waste cotton its to compare the decline of foaming PVC cost more.
