Abstract
Industrial fabrics which contain thermoplastic weft or filling filaments characterized by having at least one segment of the filament's cross sectional area consisting of a foamed polymer are described. The unfoamed segment or segments of the filament contribute axial strength while the foamed segment or segments of the filament contribute to radial compressibility. Industrial fabrics utilizing these filaments have reduced permeability, reduced weft denier, and improved fabric rigidity.
