Warp knitting elastic fabric and method of fabricating therefore

Abstract

Warp knitting fabric having a double needle overlap structure forming two loops on two adjacent needles in the same course, and loops being formed from double yarns one of which is a chemical filament yarn and the other yarn is a spandex yarn, and both of the yarns being knitted with the same lapping movement.

What is claimed is: 
     
         1 . A warp knitting fabric comprising a double needle overlap forming two loops on two adjacent needles in the same course, said loops being formed from double yarns one of which is a chemical filament yarn with the other being a spandex yarn, and both yarns being knitted with the same lapping movement. 
     
     
         2 . The warp knitting fabric of  claim 1 , wherein a complete repeat of said lapping movement consists of (a) swing in to the front the needle, (b) overlap two needle spaces to the right, (c) swing out to the back of the needle, (d) underlap one needle space to the right to complete a first course, (e) swing in, (f) overlaps two needle spaces to the left, (g) swing back, and (h) underlap one needle space to the left to complete a second course. 
     
     
         3 . The warp knitting fabric of  claim 1 , wherein said chemical filament yarn is nylon.
