Abstract
A method of making a reinforcing fabric having wide angles between the warp yarns and the weft yarns by helically folding on itself a strip of fabric which has been skewed such that the angle .alpha. between the warp yarns and the weft yarns is from 100.degree. to 140.degree..
Claims4
A method for producing a fabric having a wide angle between warp yarns and weft yarns comprising:
- a) providing a strip of leno fabric of a predetermined width having warp yarns and weft yarns;
- b) skewing the fabric strip so that the angle between the warp yarns and the weft yarns is from 100.degree. to 140.degree.;
- and
- c) helically folding the strip upon itself with edges butted or slightly overlapped to provide a two-layered fabric strip with an angle between the warp yarns and the weft yarns in the longitudinal direction of the folded strip of from 100.degree. to 140.degree..
