    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 translation: 使用具有泡沫结节的开放网状增强泡沫层制造砖或辊形地毯。 制造地毯，其具有主要背衬，毯子纤维束通过该主背衬簇绒，以及将刷毛簇锁定在适当位置的预涂层，以防止容易地提取纤维，从而提供簇绒面和相对光滑的背面。 具有泡沫结节的泡沫层与相对平滑的背面紧密接触，并且基本上永久地粘附到其上，产生基本上防止卷曲或隆起（或显着减小）的地毯或辊，并且可以安装 如果需要，没有粘合剂。 粘合可以通过使用随后在低温（约310°F或更低）下熔合的非熔合粘合剂制剂来实施，或者通过迫使具有泡沫结块的泡沫层与地毯接触而在热熔背衬 仍然是流体形式，或者通过在地毯和泡沫片之间使用热塑性层。

    Abstract: Various implementations include a filament that includes three lobes that extend from a central portion of the filament, and the central portion defines an axial void. Each lobe bulges outwardly at its proximal end adjacent the central portion and has edges that form a continuous concave curve toward its distal end relative to an axis A-A that extends through the distal end of the respective lobe and the central portion of the filament. Thus, a width of each lobe at the proximal end thereof is greater than a width of each lobe at or adjacent the distal end, and adjacent edges of adjacent lobes intersect each other at concave proximal ends of the adjacent edges.
