Abstract
Abstract An elastic compression bandage of narrow woven fabric includes cotton weft yarn picks and textured stretch nylon multifilament warp yarns having total deniers in the range of from 210 to 560. The construction provides from 10 to 16 weft yarn picks per inch and from 30 to 40 warp yarns per inch in the as-woven fabric. Spaced apart across the width of the fabric are pairs of warp yarns interwoven with the weft yarn picks in a leno construction that provides high frictional resistance to slippage between those warp yarns and the weft yarns. The ratio of leno pairs to non-leno warp yarns is in the range of from 1/6 to 1/14. The non-leno warp yarns and the weft yarn picks are interwoven in a 1×1 weave. The leno pairs are in a pretensioned state when the bandage is in an unstretched condition.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
211 words
An elastic compression bandage extendable to a tensioned length at least about twice its relaxed length and being formed by a narrow woven fabric, the contraction power of said bandage being provided by textured stretch nylon warp yarns that are interwoven under tension with weft yarn picks and that are bulked and shrunk by treatment subsequent to such weaving, said fabric comprising: a plurality of weft yarn picks in the range of from about 10 to about 16 picks per inch of tensioned length of the as-woven fabric; and a plurality of warp yarns disposed across the entire width of the fabric with a density in the range of from about 30 to about 40 yarns per inch of width of the as-woven fabric, each warp yarn being stretchable and formed of textured stretch nylon, the total deniers of each warp being in the range of from about 210 to about 560; said plurality of warp yarns including spaced apart pairs of leno warps and groups of non-leno warps between said pairs of leno warps, with the ratio of leno pairs to non-leno warp yarns being in the range of from about 1/6 to 1/14 and the non-leno warp yarns and the weft yarn picks being interwoven in a 1×1 weave.

Claim 3
Dependent Claim
31 words
An elastic compression bandage according to claim 1, wherein each of said warp yarns is a ply yarn made up of a plurality of ends of 70 denier, 17 filament, yarn.
Claim 4
Dependent Claim
36 words
An elastic compression bandage according to claim 2, wherein each weft yarn pick is constituted by a double strand of cotton yarn of a size corresponding to yarn numbers in the range from 12s to 26s.
Claim 5
Dependent Claim
92 words
An elastic compression bandage according to claim 3, wherein said cotton weft yarns are of sizes corresponding approximately to the yarn number 20s, said weft yarn picks are present at a density of about 13.5 picks per inch of the as-woven fabric, said warp yarns are 6 ply yarns present in the as-woven fabric at a density of about 34 to 35 warp yarns per inch of the fabric width, and the number of non-leno warps in at least most of said groups located between pairs of leno warps is about 10.
Claim 6
Dependent Claim

Claim 9
Independent Claim
177 words
A method of making an elastic compression bandage of improved fabric stability, comprising providing a single warp beam on which textured stretch nylon yarns are wound at generally the same tension level, such yarns having a denier in the range of from 210 to 560 and being present on the beam in sufficient numbers that 30 to 40 warp yarns per inch of bandage width can be supplied from the beam to a weaving station, delivering the yarns from said beam at substantially equal mass rates by rotation of said beam, and manipulating said warp yarns and inserting weft yarn picks at said weaving station to provide (a) spaced apart leno warp pairs interlocked with said picks and (b) groups of 6 to 14 non-leno warps interwoven with said picks in a 1×1 weave in zones between leno pairs, whereby the lengths of said leno warp in the bandage are greater than the lengths of said non-leno warps, so that the tension level in the leno warps is higher than the tension level of the remaining warps.
Claim 10
Independent Claim
177 words
