Abstract
Abstract An elastic fabric containing producers twist continuous filament yarns, which in spite of their features make it possible to obtain a fabric having high elasticity and power stretch indexes; said synthetic yarns are knit just as issued from spinning, without previously being submitted to any texturing or warping operation, in a large diameter interlock type circular machine, with two sets of needles, on a pique basis and with interlacing interlock and jersey courses. In the interlock courses a first synthetic yarn is incorporated, while in the jersey courses a polyurethane originated elastomeric yarn tensioned under control, having as a companion or carrier yarn a second synthetic yarn, is incorporated.
