Claims16
A papermakers' belt for use in a papermaking machine and comprised of ultra-high modulus load-bearing yarns comprised of poly (para-phenylene terephthalamide).
A papermakers' belt for use in a papermaking machine and comprising ultra-high modulus load-bearing yarns comprised of poly (para-phenylene terephthalamide) and non-load bearing yarns having a modulus of elasticity less than 150 grams per denier.
A papermakers' belt for use in a papermaking machine and comprising ultra-high modulus load bearing yarns which are coated with nylon resin and comprise multifilament poly(para-phenylene terephthalamide) fibers, and the non-load bearing yarns comprise multifilament polyester having a modulus of elasticity less than 150 grams per denier.
A papermakers' belt for use in a papermaking machine and comprising ultra-high modulus load bearing yarns which are coated with nylon resin and comprise multifilament poly(para-phenylene terephthalamide) fibers, and the non-load bearing yarns comprise multifilament nylon having a modulus of elasticity less than 150 grams per denier.
A papermakers' belt for use in a papermaking machine and comprising ultra-high modulus load bearing yarns which are coated with nylon resin and comprise multifilament poly(para-phenylene terephthalamide) fibers, and the non-load bearing yarns comprise monofilament nylon having a modulus of elasticity less than 150 grams per denier.
A papermakers' belt woven in a four-harness satin weave for use in a papermaking machine and comprising ultra-high modulus load-bearing yarns comprised of poly (para-phenylene terephthalamide), and wherein said belt is resin-coated.
