The present invention relates to felt for a car interior material which is adapted to maximize insulation, sound absorption, sound insulation, and waterproof functions required as car interior materials and to a manufacturing method of felt for a car interior material as above described. More specifically, felt for a car interior material having insulation, sound absorption, sound insulation, and waterproof functions in order to achieve the above object are comprised of polyethylene terephthalate (PET hollow monofilament), polypropylene (PPT monofilament), and heat-melting yarns (LM monofilament). The present invention comprises PET hollow monofilaments, LM monofilaments, and PP monofilaments, whereby it is easy to manufacture products in a frame due to excellent moldability, and there is an effect of improving productivity and quality of products. |
