Abstract
Abstract A knit fabric is provided in which warp knit stitch chains are formed at spaces between inlaid warp ends and have loops thereof sinuously interlaced with filling ends laid at opposite sides of the warp ends so that the filling ends are held against the warp ends and both warp and filling ends are caused to interact in a manner producing an appearance approaching that of a woven structure. The method of forming this fabric and means for doing so are also disclosed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
In knit fabric incorporating an inlay of spaced warp ends with filling ends laid at opposite sides of said warp ends across the full fabric width and warp knit stitch chains formed in the spaces between said warp ends, an improved woven fabric simulation comprising a sinuous interlacinG of loops of said stitch chains with filling ends at both sides of said warp ends by which said filling ends are held against said warp ends and are forced inwardly therebetween so that both warp and filling ends are caused to undulate as a result of mutual interaction in a manner producing an appearance approaching that of a woven structure.
Claim 2
Dependent Claim
109 words
In knit fabric incorporating an inlay of spaced warp ends with filling ends laid at opposite sides of said warp ends across the full fabric width and warp knit stitch chains formed in the spaces between said warp ends, an improved woven fabric simulation comprising a sinuous interlacinG of loops of said stitch chains with filling ends at both sides of said warp ends by which said filling ends are held against said warp ends and are forced inwardly therebetween so that both warp and filling ends are caused to undulate as a result of mutual interaction in a manner producing an appearance approaching that of a woven structure.
Claim 3
Dependent Claim
29 words
In knit fabric, the improvement defined in claim 1 wherein the loops of said stitch chains pass outside of all filling ends at both sides of said warp ends.
Claim 4
Dependent Claim
24 words
In knit fabric, the improvement defined in claim 2 wherein connecting segments run between said loops entirely at one face of the resulting fabric.
Claim 5
Dependent Claim
17 words
In knit fabric, the improvement defined in claim 2 wherein said stitch chains are links-links stitch chains.
Claim 6
Dependent Claim
48 words
In knit fabric, the improvement defined in claim 1 wherein certain loops of said stitch chains are elongated in an extent sufficient to pass outside of at least two filling ends at one side of said warp ends without interlacing with a filling end at the other side.
Claim 7
Dependent Claim
28 words
In knit fabric, the improvement defined in claim 1 wherein certain weftwise rows of loops of said stitch chains are transferred to adjacent spaces between said warp ends.
Claim 8
Dependent Claim
38 words
In knit fabric, the improvement defined in claim 1 wherein connecting segments between loops of said stitch chains are shifted at certain weftwise rows of loops to form continuing stitch chains at adjacent spaces between said warp ends.
