Abstract
Abstract A knit fabric is made to simulate a woven structure by arranging fancy warp stitch chains at spacings between inlaid warp ends so that filling ends laid at one side of the warp ends are knit-in while filling ends laid at the other side remain simply laid-in and are held in place by interaction of the warp ends and warp stitch chains thereat.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
In warp knit fabric incorporating an inlay of spaced warp ends with filling ends laid at opposite sides of said warp ends and warp stitch chains running in the spaces between said warp ends, the improvement which comprises an arrangement of the loops of said stitch chains so that they pass outside of all filling ends at one side of said warp ends and Inside all filling ends at the other side, with connecting segments between said loops running outside of any filling end at said other warp end side adjacent the loop throat and outside any intervening filling end at said one warp end side and then forming a sub-loop portion at the loop bight that wraps from inside out around any adjacent filling end at said other warp end side before connecting with the next succeeding loop.
Claim 2
Dependent Claim

In warp knit fabric incorporating an inlay of spaced warp ends with filling ends laid at opposite sides of said warp ends and warp stitch chains running in the spaces between said warp ends, the improvement which comprises an arrangement of the loops of said stitch chains so that they pass outside of all filling ends at one side of said warp ends and Inside all filling ends at the other side, with connecting segments between said loops running outside of any filling end at said other warp end side adjacent the loop throat and outside any intervening filling end at said one warp end side and then forming a sub-loop portion at the loop bight that wraps from inside out around any adjacent filling end at said other warp end side before connecting with the next succeeding loop.
Claim 3
Dependent Claim
28 words
In warp knit fabric, the improvement defined in claim 1 in which said warp stitch chains are formed of appreciably finer yarn than said warp and filling ends.
Claim 4
Dependent Claim
56 words
In warp knit fabric, the improvement defined in claim 1 in which said filling ends are alternately laid at opposite sides of said warp ends and are regularly spaced so that each loop of said warp stitch chains has respective filling ends adjacent the throat and the bight thereof and runs outside an intervening filling end.
Claim 5
Dependent Claim
34 words
In warp knit fabric, the improvement defined in claim 1 in which the filling ends at said one warp end side are laid in a lesser number than at said other warp end side.
Claim 6
Dependent Claim
38 words
In warp knit fabric, the improvement defined in claim 1 in which the filling ends on at least one side of said warp ends are laid at a spacing that avoids some of the warp stitch chain loops.
