Knitted and woven fabric and garments made therewith

Abstract

A knit fabric has a first yarn having a first spandex fibre core and a rayon fibre sheath and a second yarn having a second spandex fibre core and a nylon fibre sheath. A woven fabric has a warp yarn having a first spandex core and a cotton fibre sheath and a weft yarn having a second spandex core and a blended polyester and rayon fibre sheath. Garments are made from these fabrics.
