Appeal 2006-2969
Application 10/394,075
Claims 1, 25, and 31 illustrate Appellants’ invention of a textile
material having a discontinuous hydrophobic treatment on its surface, and
are representative of the claims on appeal:
1. A textile material comprising a surface and a discontinuous
hydrophobic treatment located on said surface, said discontinuous
hydrophobic treatment comprising discrete, individual hydrophobic particles
that are more hydrophobic than said surface, said hydrophobic particles
adhering directly to the surface, said surface consisting essentially of a
surface of a fiber or a yarn,
wherein said discontinuous hydrophobic treatment is in the range of
about 0.1% to about 8% by weight of said textile material and increases the
water release weight rate near dryness of said textile.
25. A fabric comprising a hydrophilic surface and a discontinuous
hydrophobic treatment that is more hydrophobic than said hydrophilic
surface, said discontinuous hydrophobic treatment comprising discrete,
individual particles located directly on said hydrophilic surface, said
hydrophilic surface consisting essentially of a surface of a fiber or a yarn,
wherein said discontinuous hydrophobic treatment is in the range of
about 0.1% to about 8% by weight of said fabric and increases the water
release weight rate near dryness of said fabric.
31. A textile material comprising a surface and a discontinuous
hydrophobic treatment located on said surface, said surface consisting
essentially of a surface of a fiber or a yarn, said discontinuous hydrophobic
treatment comprising discrete, individual particles of one or more of
polyvinyl acetate and a polyvinyl acetate/acrylic copolymer, said individual
particles adhering directly to the surface, wherein said discontinuous
hydrophobic treatment is present in an amount sufficient to increase the
water release weight rate near dryness of said textile.
