Filed:

Aug 17, 1993

Appl. No.:

8/107491

Inventors:

Joseph V. Marra - Wilmington DE

Assignee:

Applied Extrusion Technologies, Inc. - Middletown DE

International Classification:

A01J 2100
A01J 2512

US Classification:

424443

Abstract:

An adhesive hydrogel product includes a mixture comprising water, and a thermoplastic, water-soluble polymer extruded in a dry state. The thermoplastic, water-soluble polymer constitutes the principal water-soluble polymer of the mixture and is present in the mixture in a concentration, by weight, of at least 15 percent. The mixture having been exposed to a dose of radiant energy effective to provide an adhesive hydrophilic gel having a gel breaking strength of at least 10 p. s. i. , and an absorption capacity per mil of thickness of the gel in excess of 10% by weight, and more preferably in excess of 30% by weight. The method includes the steps of directing a substrate including an extruded, thermoplastic, water-soluble polymer through a liquid bath at a speed for causing the substrate to absorb approximately 30 percent to about 80 percent, by weight, of said liquid to thereby convert said water-soluble polymer into a hydrogel; separating the substrate into discrete hydrogel products; packaging the discrete hydrogel products in moisture-impervious packages, and subjecting the packaged hydrogel products to a dose of radiation effective to provide an adhesive hydrogel having a gel breaking strength of at least 10 p. s. i. , and an absorption capacity per mil of thickness of the gel in excess of 10%, by weight, and more preferably in excess of 30% by weight.

US Classification:

210483

Abstract:

An apertured film extruded from a crystalline, thermoplastic, extrudable fluoroplastic material. The film includes spaced-apart strand segments defining apertures therebetween and has at least 10 strand segments per inch. The film has a thickness of 2-12 mils and a Frazier air permeability number in the range of 200-2,000. The invention includes a process for preparing an apertured thermoplastic film by a single-sided embossing method. The process includes the steps of extruding in the machine direction, a film of a molten, crystalline, thermoplastic, extrudable, fluoroplastic material. The molten extruded film is passed in the machine direction through the nip of two metal rollers. One of the rollers has a substantially smooth surface, having a convex configuration as viewed from a direction substantially parallel to the axis of the roll, such that the diameter in the center of the roll is in the range of 8-12 mils greater than the diameter at the ends of the roller for a 40 inch roller. The other roller includes a plurality of discrete, raised projections disposed in a pattern.
