Abstract

The invention relates to a production method for a composite fiber car carpet. The production method includes the following steps that an EVA recoating material is placed on a composite fiber PET coating; a carpet base material is placed in an oven to be heated; the heated carpet base material is placed between an upper mold and a lower mold of a compression molding machine so as to be molded in a compression mode; a semi-finished composite fiber carpet is placed on a cooling jig to be cooled to the room temperature, so that shaping is completed; the shaped semi-finished composite fiber carpet is cut through a water jet cutter; and a car carpet pedal mat is riveted to a composite fiber carpet body through a riveting machine, cushion cotton is attached to the fool-proof position of the EVA recoating material of the composite fiber carpet body through glue, and hooks are mounted on a PET flock layer of the composite fiber carpet body. By means of the production method, performance indexes such as sound absorption, sound insulation, environmental protection and light weight of a car carpet assembly are achieved; and the weight of the car carpet is greatly lowered, the light-weight design requirement of a whole car is met, and the manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of production methods of automobile interior parts, and in particular relates to a production method of composite fiber automobile carpets. Background technique [0002] The car carpet is installed at the bottom of the car compartment to play the role of heat insulation, sound insulation and sound absorption. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the interior of a car, like the shape of a car, has become an important factor for people to choose a car. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as high sound absorption, high sound insulation, low weight, strong heat insulation, and environmental protection of automobile carpets have become bottlenecks, restricting the development of automobile carpets. Existing car carpet ...
