Abstract
Abstract A warp knitted fabric with surface interest patterning is formed from full sets of warp threads of yarn. The surface interest patterning is continuous throughout the length of the fabric and includes groups of wales, each group being separated from adjacent wales by exaggerated spacing. Three different methods for obtaining the surface interest patterning on a two-bar single needle bed warp knitting machine are disclosed.
