| titleOfInvention | Method for Manufacturing Floor Carpet Having Sound Insulation Layer Integrated with Sound Absorption Using the Sound Insulation Material Having Low Weight Thermoplastic Polyethylene |
| abstract | The present invention is a method of manufacturing a car floor carpet in which a sound insulation coating extrusion layer including the sound insulation material, a latex layer, and a nonwoven surface layer are sequentially stacked in a height direction from the bottom surface, wherein the sound insulation coating extrusion layer is the sound insulation coating After dispersing 80 to 90% by weight of polyethylene chips in 10 to 20% by weight of EVA rubber based on the total weight of the extruded layer, a sound insulating coating extruded layer manufacturing process for extruding the same; Manufacturing a latex layer including acrylic latex on the surface of the sound insulation coating extruded layer; Forming a nonwoven fabric layer to form a nonwoven fabric layer on the surface of the latex layer; A needle punching process of needle punching the surface of the nonwoven fabric layer; Including, wherein the non-woven fabric layer forming process is characterized in that after spinning the non-woven fabric, a first carding process, a second carding process, and a web lamination process are performed, and the web lamination process is based on a height direction from the surface of the latex layer. As a result, it provides a method of manufacturing a floor carpet for an automobile, characterized in that it is carried out at a bonding angle of 50 to 65°. |
