ABSTRACT:
A no-gel latex foam is formed by curing a no-gel latex foam froth on a water vapor permeable foraminous support that has been coated with a flock. During curing, the foam froth dehydrates through an upper free surface and at its lower supported surface through the flock and the foraminous supporting means. When the cured foam is removed from the foraminous supporting means, a portion of the flock adheres to the foam undersurface and another portion of the flock is left as a residue.
