Abstract
Poromeric plastic coated fabrics containing embedded therein microspheres disposed in natural or synthetic clustered domains each constituted by a matrix insoluble in the coating composition, the clustered domains adjacent to one another but spatially separated horizontally and vertically to provide substantially uniform microporosity throughout the coating.
Claims10
A microporous plastic composition comprising a synthetic resin matrix and a network of domains dispersed throughout said matrix;
- each of said domains comprised of plurality of porous microspheres bonded together with a bonding agent that is insoluble in the synthetic resin matrix;
- said composition having a relatively uniform gas permeability.
A microporous plastic composition comprising a synthetic resin matrix and a network of contiguous domains dispersed throughout said matrix;
- each of said domains comprised of a plurality of discrete porous microspheres bonded together with a bonding agent that is insoluble in the synthetic resin matrix.
A coated fabric comprising, in combination, a fabric layer, a flexible coating adhering to said fabric layer comprised of a synthetic resin matrix and a network of domains dispersed throughout said synthetic resin matrix;
- each of said domains comprised of a plurality of microspheres bonded together with a bonding agent which is insoluble in said synthetic resin matrix.
