Abstract

The invention relates to a method for manufacturing a composite fabric automobile roof, which is characterized by comprising the following process steps of: putting composite chloro fiber fabrics into an open-type fabric oven for heating; heating a roof base material in a heating oven; putting the heated composite chloro fiber fabrics on the roof base material and feeding into a die to press into a semi-finished product; putting the semi-finished product on a water jet cutting jig for cutting so as to cut oddments; blowing impurities on the surface of the semi-finished product completely and wiping oil stains on the surface by using alcohol to obtain a finished product. The method of the invention solves the problem of performance indexes such as flame retardance, stain resistance, easy cleaning and the like of the roof. Through a test, the surface of the automobile roof cannot be polluted.

Description

technical field [0001] The invention relates to a method for producing a car roof, in particular to a method for manufacturing a composite fabric car roof, which belongs to the technical field of car interior parts. Background technique [0002] The car roof is a decorative part installed on the top sheet metal of the car cockpit, which plays the role of heat insulation, absorbing part of the noise during driving and beautifying the cockpit. 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 flame retardancy and cleaning resistance of the canopy become bottlenecks, restricting the development of the canopy. The existing canopy mainly has the following...
