<p>A polyurethane elastomeric filament-containing weft knit fabric is obtained by plating a bare yarn of highly fusible, alkali-resistant polyurethane elastomeric filament having at least 50% retention of tenacity following dry heat treatment under 100% extension at 150°C for 45 seconds, a melting point of 180°C or below, and at least 60% retention of tenacity following treatment in a 2 g/L aqueous sodium hydroxide solution under 100% extension at 100°C for 60 minutes at every loop of a weft knit fabric having a 1×1 rib. knit structure or a center yarn-containing reversible knit structure composed of at least one type of non-elastomeric yarn, then heat setting the plated structure so as to thermally fuse the highly fusible, alkali-resistant polyurethane elastomeric filaments to each other or to the non-elastomeric yarns at crossover points therebetween.</p> |
