LIGHTWEIGHT AND SOUND ABSORBING INTERIOR MATERIALS FOR AUTOMOBILE CONTAINING WASTE FIBERS AND THEIR PREPARATION

摘要

More particularly, the present invention relates to an automobile interior material for a wheel guard comprising a skin layer, a base layer including waste fibers, and a polyethylene film, and an automobile interior material made of PET fibers A skin layer, and a base layer containing waste fibers, and a method for manufacturing the same.According to the present invention, it is possible to replace a conventional polypropylene plastic material with a waste fiber nonwoven fabric material, thereby making it lighter, more economical and environmentally friendly, and simultaneously heating each side at different temperatures, The process can simplify the process, further economically, and greatly increase the productivity. Further, although the composite structure is a two-layer or three-layer structure, it is possible to produce each layer integrally and to manufacture without additional felt attachment or a sound absorbing material adhering step, thereby improving productivity and reducing production cost.
