    Abstract: The resistance to deformation for extensions ranging up to 70% of the breaking elongation of a polyurethane-coated circular weft-knit or circular warp-knit fabric, especially such a fabric made from textured continuous-filament yarn with interlock bonding, is reduced by a polysiloxane elastomer finish to a value as low as one-fifth of that of polyurethane-coated fabric which does not have a polysiloxane elastomer finish. Such fabric is especially suitable for sport clothing, as well as all-weather clothing and stylish clothing.
