Abstract
An absorbent material comprising a mat of dry-formed cellulose fibers integrated with an air-laid non-woven gauze of reinforcing textile fibers. A method of producing this material by air-laying textile fibers on a wire to form a non-woven gauze, whereafter a mat of cellulose fibers is formed on the textile fiber non-woven gauze. The use of the material as an absorbent structure in an absorbent product. A method of producing an absorbent structure comprised of cellulose fibers and reinforcing textile fibers in which a mat of dry-formed cellulose fibers integrated with an air-laid non-woven gauze of reinforcing fibers is defined and mat-formed. An absorbent structure obtained by this method.
Claims32
An absorbent material comprising a mat of dry-laid cellulose fibers integrated with an air-laid non-woven gauze comprised of reinforcing textile fibers obtained by directly dry-laying the cellulose fibers on the newly formed gauze of textile fibers so that the cellulose fibers achieve a sufficient bonding with the textile fibers without any bonding agent.
A method of producing an absorbent material that includes a mat of dry-laid cellulose fibers integrated with an air-laid non-woven gauze comprised of reinforcing textile fibers, comprising:
- air-forming textile fibers with an air-doffing apparatus on a wire to form a non-woven gauze;
- and
- directly dry-laying the cellulose fibers on the newly formed non-woven gauze of textile fibers to integrate the cellulose fibers with the non-woven gauze and form a mat wherein the cellulose fibers achieve a sufficient bonding with the textile fibers without any bonding agent.
A process for producing an absorbent product, comprising:
- air-forming textile fibers with an air-doffing apparatus on a wire to form a non-woven gauze;
- directly dry-laying the cellulose fibers on the newly formed non-woven gauze of textile fibers to integrate the cellulose fibers with the non-woven gauze and form a mat wherein the cellulose fibers achieve a sufficient bonding with the textile fibers without any bonding agent;
- and
- including the mat in an absorbent product.
An absorbent structure including cellulose fibers reinforced with textile fibers, the structure having been produced by defiberating and mat-forming an absorbent material comprising a dry-laid mat of cellulose fibers integrated with an air-laid non-woven gauze of long reinforcing textile fibers, wherein the absorbent material is obtained by directly dry-laying the cellulose fibers on the newly formed gauze of textile fibers so that the cellulose fibers achieve a sufficient bonding with the textile fibers without any bonding agent.
A method of producing an absorbent structure including cellulose fibers and reinforcing textile fibers, comprising:

- directly dry-laying the cellulose fibers on the newly formed non-woven gauze of textile fibers to integrate the cellulose fibers with the non-woven gauze and form a mat wherein the cellulose fibers achieve a sufficient bonding with the textile fibers without any bonding agent;
- and
- defiberating and mat-forming the integrated mat of cellulose fibers and non-woven gauze.
