Abstract

Abstract Disclosed is a warp knitted narrow lace and method of forming the same in which purls or decorative loops are formed in a curved line along curved scallops of the lace. This warp knitted narrow lace is manufactured by knitting the base fabric into a Raschel lace having a scalloped edge and simultaneously knitting laid in yarns into the edges forming the scalloped edge of the lace in such manner that the laid in yarns are laid in with stitches of soluble yarns and/or ravel yarns located outside base fabric at the outermost portion of the scalloped edge and with stitches of the base fabric in the indentations of the scallops. Dissolving the soluble yarns and/or pulling out the ravel yarns in the area of the outermost edge of the scallops, and cutting the stitches of the base fabric outwards of the purls in the indentations of the scallops results in the formation of a novel lace having purls formed in a curved line along the entire scallops.
