Abstract
The present invention provides a unique knit construction having a nonfiberglass stiffness-controlling yarn in the fabric of the backing. Preferably, the nonfiberglass stiffness-controlling yarn is used in combination with a heat shrinkable yarn or a stretch yarn, and alternatively a nonfiberglass microdenier yarn. More preferably, the nonfiberglass stiffness-controlling yarn is in combination with a stretch yarn and a nonfiberglass microdenier yarn. Most preferably, the nonfiberglass stiffness-controlling yarn is in combination with a heat shrinkable, elastically extensible yarn, and a nonfiberglass microdenier yarn.
Claims20
A resin-coated sheet material comprising:
- (a) a knit fabric comprising a nonfiberglass, microdenier yarn in a weft in-lay and a generally inelastic stiffness-controlling yarn having a modulus of greater than about 5 grams per denier as a weft insert;
- and
- (b) a curable resin coated on the fabric.
A resin-coated sheet material comprising:
- (a) a knit fabric comprising a nonfiberglass, microdenier yarn in a weft in-lay and a stretch yarn in the wales of a chain stitch, wherein the fabric has been calendared;
- and
- (b) a curable resin coated on the fabric.
