PRIMARY CARPET BACKING

摘要

A nonwoven fabric is provided for a primary carpet backing comprising a bicomponent filament of polymeric core/sheath-type, the polymeric core component of which has a higher melting point than the polymeric sheath component, said bicomponent filaments are bonded together by the application of heat to form said fabric, characterized in that the polymeric sheath component is selected from the group containing polypropylene and copolymers comprising polypropylene and/or blends thereof. The invention is further directed to a process of manufacturing such nonwoven fabrics and to articles, such as car carpets, comprising them.
