Abstract: A seating structure comprising a warp knit fabric attached to a frame, the fabric comprising at least one restraining cord adjacent each selvage of the fabric and elastomeric monofilament perpendicular to each restraining cord, the elastomeric monofilament being located along the full width of the fabric in the weft direction and substantially continuous from course to course, the structure being characterized by excellent long-term wear and seating comfort, particularly for automotive applications.

Abstract: Polyphenylene sulfide blends with melt extrudable polymers form novel monofilaments. The monofilament is prepared by extruding a mixture of the linear polyphenylene sulfide and the melt extrudable polymer to form a monofilament blend, quenching the monofilament and thereafter drawing the monofilament to a ratio of from about 3:1 to 6:1. The resulting filament can be employed for the manufacture of fabric.

Abstract: Decorative sheet-type covering material having both PVC and polyurethane wear layers is made by first forming a sheet of gelled foamable PVC plastisol or organosol on a substrate. A layer of nonfoamable PVC plastisol or organosol is then applied to the gelled foamable layer and gelled, but not cured. A layer of polyurethane is then applied to the gelled nonfoamable layer and the entire sheet is heated to a temperature sufficient to decompose the blowing agent in the foamable layer and cure both of the PVC layers and the polyurethane layer.

Abstract: Sections of sheet vinyl flooring having polyurethane wear layers are joined together with a sealing composition comprising between about 10 and about 75 wt. % uncured polyurethane, between about 20 and about 85 wt. % tetrahydrofuran and between about 5 and about 60 wt. % of an organic solvent for the polyurethane. The uncured polyurethane is preferably in the form of polyurethane prepolymer of the moisture/cure type and the organic solvent for the polyurethane preferably has an evaporation rate not more than 95 percent of the evaporation rate of the tetrahydrofuran.

Abstract: A textured polyurethane surface is created from a vinyl substrate by first forming a smooth, uncured polyurethane coating on the substrate and then heating the thus coated substrate to a temperature between about 100.degree. and about 160.degree. C for 1 to 10 minutes followed by heating to temperatures of 170.degree. to 210.degree. C for 0.5 to 10 minutes. A textured surface may also be provided on a vinyl substrate having a previously cured polyurethane coating thereon by waiting at least about 1 week after the urethane coating has been cured and then heating the coated substrate to a temperature between about 140.degree. C and about 210.degree. C for 0.1 to 10 minutes. A preferred application is in the creation of textured surfaces on sheet vinyl floor and wall coverings coated with polyurethane.
