摘要:
A method of forming an elastic cloth structure comprising fibers of synthetic, organic, relatively elastomeric polymer and fibers of a synthetic, organic, elongatable, but relatively nonelastic polymer. The relatively elastomeric fibers and the elongatable but relatively nonelastic fibers are forwarded for well dispersed random lay down of an unbonded web with random fiber crossings on a porous forming surface. Some of the fiber crossings are then bonded to provide a coherent bonded cloth web and the web is stretched to elongate some of the fibers in at least one direction. The web is then released so that retraction by the relatively elastomeric fibers provides looping and bunching of the elongated relatively nonelastic fibers to thereby provide a low modulus of elasticity in the direction in which the web was worked.
