    Abstract: A carpet in tile or roll form is produced using an open mesh reinforced foam layer with foam nodules. The carpet is produced having a primary backing through which carpet fiber bundles are tufted and a precoat layer which locks the tufts in place to prevent easy extraction of the fibers so that a tufted face and a relatively smooth back face are provided. The foam layer with foam nodules is brought into intimate contact with the relatively smooth back face, and is substantially permanently adhered to it producing a carpet tile or roll that is substantially prevented from curling or doming (or they are significantly reduced) and may be installed without adhesive if desired. Adhering may be practiced by using a non-fused adhesive formulation which is subsequently fused at a low temperature (about 310null F. or less), or by forcing the foam layer with foam nodules into contact with the carpet back while the hot melt backing is still in a fluid form, or by use of a thermoplastic layer between the carpet and foam sheet.

    Abstract: The disclosure relates to a carpet product, a process for manufacturing carpet, and an apparatus used in a carpet manufacturing process. The carpet product is made from tufted polymer filament yarn wherein the individual yarn filaments of the yarn back loops are integrally fused so that the carpet resists fuzzing. The primary backing preferably is modified polypropylene in the fill direction. Further, the primary backing may be coated with a polymer before tufting to adhere or integrally fuse the inside of the fiber tuft to the primary backing. An optional secondary backing is preferably made of tape yarn in both directions. The process includes providing a carpet base having a primary backing penetrated by yarn, applying heat to the underside of the primary backing, extruding a heated sheet of polymer and continuously contacting the heated extruded sheet of polymer with the base. The apparatus includes a source of carpet precursor, a heated cylinder for heating the underside of the carpet, an extruder and a casting roll against which the extruded sheet and heated carpet are pressed.

    Abstract translation: 本公开涉及地毯产品，用于制造地毯的方法以及用于地毯制造过程中的装置。 地毯产品由簇绒聚合物长丝纱制成，其中回丝圈的单根纱线整体熔合，使得地毯抵抗绒毛。 主要的背衬优选在填充方向上是改性的聚丙烯。 此外，主要背衬可以在簇绒之前用聚合物涂覆以将纤维束的内部粘附或整体熔合到主衬里。 可选的辅助衬垫优选地在两个方向上由带状纱线制成。 该方法包括提供具有由纱线渗透的主要背衬的地毯基底，将热量施加到主背衬的下侧，挤出加热的聚合物片材，并将加热的挤出的聚合物片材与基底连续接触。 该设备包括地毯前体源，用于加热地毯下侧的加热缸，挤压机和流延辊，挤压的片材和加热的地毯被挤压在该辊上。
