Abstract

The invention relates to a production technique for a soft-hard-layer carpet of an automobile and relates to the technical field of production of inner trims of automobiles. The soft-hard-layer carpetcomprises a face carpet body, hard-layer fiber felt, solvent cement and soft-layer fiber felt. According to the production technique for the soft-hard-layer carpet of the automobile, firstly, the hard-layer fiber felt and the soft-layer fiber felt are subjected to hot-pressing and thickness controlling, then, the hard-layer fiber felt is attached to the heated face carpet body, and the solvent cement is sprayed to the hard-layer fiber felt and the soft-layer fiber felt to attach the hard-layer fiber felt to the soft-layer fiber felt. The thickness of the hard-layer fiber felt can be controlled strictly, so that effective controlling over the sound absorption and insulation performance of the carpet is facilitated; and the melting effect of cement power or a cement film on the face carpetbody is good, the cohesive property of the solvent cement is good, and the mechanical performance of the carpet is excellent.

Description

technical field [0001] The invention relates to a production process of soft and hard carpets for automobiles, and belongs to the technical field of production of automobile interior parts. Background technique [0002] As a material for automotive interior, carpet has become an important part of automotive interior parts due to its characteristics of shock absorption, heat insulation, and sound insulation. With the country's call for energy saving and emission reduction, automobile lightweight is becoming the trend of the times. Fiber felt is a felt product made of a variety of fibers through mixing, molding, drying, and shaping processes. Because of its simple structure and light weight, its combination with surface blankets has been widely used in automobiles. Use a rug. And because the fibers it contains largely come from the recycling of waste fiber products, it conforms to the principle of recycling advocated by the state. But the carpet produced by the existing tec...
