Abstract
The present invention provides compressed paper webs that maintain a substantial amount of their absorptive capacity and wet strength when compressed. The compressed webs bounce back to a portion of their uncompressed state when wetted. The present compressed webs allow more towels to be added to a dispenser without substantially sacrificing the absorbent capacity or the strength of the towels.
Claims (21)
1. An absorbent paper product comprising a compressed paper based web, wherein said compressed paper-based web has been compressed from an uncompressed paper-based web so as to have its caliper reduced from an original caliper, said reduced caliper being from 50% to about 90% of said original caliper, said compressed paper-based web recovering at least about 70% of its original caliper when said compressed paper based is saturated with liquid.
2. The product of claim 1 wherein said reduced caliper is from about 60% to about 90% of said original caliper.
3. The product of claim 1 wherein said reduced caliper is from about 70% to about 90% of said original caliper.
4. The product of claim 1 wherein said reduced caliper is from about 75% to about 90% of said original caliper.
5. The product of claim 1 wherein said reduced caliper is from about 80% to about 90% of said original caliper.
6. A process for forming a compressed paper-based web, said process comprising the steps of:
a) forming a paper-containing slurry;
b) transferring said slurry to a paper-forming wire;
c) drying said slurry so as to form an uncompressed paper-based web; and d) compressing said paper-based web by applying pressure to said web to form a compressed paper-based web, said pressure being sufficient to reduce the thickness of said uncompressed paper-based web to a caliper that is from 50% to about 90% of the original caliper of said uncompressed paper-based web.
a) forming a paper-containing slurry;
b) transferring said slurry to a paper-forming wire;
c) drying said slurry so as to form an uncompressed paper-based web; and d) compressing said paper-based web by applying pressure to said web to form a compressed paper-based web, said pressure being sufficient to reduce the thickness of said uncompressed paper-based web to a caliper that is from 50% to about 90% of the original caliper of said uncompressed paper-based web.
7. A method for making an absorbent structure comprising:
a) forming an uncompressed structure from a slurry of fibers without compacting the wet sheet during the forming or drying of said fibers; and b) compressing said uncompressed structure to a thickness of from about 50% to about 90% of the original thickness of said uncompressed structure to form a compressed structure that is capable of regaining at least 70% of its original thickness when said compressed structure is wetted.
a) forming an uncompressed structure from a slurry of fibers without compacting the wet sheet during the forming or drying of said fibers; and b) compressing said uncompressed structure to a thickness of from about 50% to about 90% of the original thickness of said uncompressed structure to form a compressed structure that is capable of regaining at least 70% of its original thickness when said compressed structure is wetted.
8. The method of claim 7 wherein said absorbent structure comprises fibers selected from the group consisting of fibers composed of natural wood pulps, synthetic resins, flax, milkweed, abaca, hemp, and cotton.
9. The method of claim 8 wherein said wood pulps comprise pulps selected from the group consisting of recycled fiber pulp and non-recycled fiber pulp.
10. A product formed according to the process of claim 7.
11. The method of claim 7 wherein said uncompressed structure is compressed to a thickness of from about 60% to about 90% of the original thickness of said uncompressed structure.
12. The method of claim 7 wherein said uncompressed structure is compressed to a thickness of from about 70% to about 90% of the original thickness of said uncompressed structure.
13. The method of claim 7 wherein said uncompressed structure is compressed to a thickness of from about 75% to about 90% of the original thickness of said uncompressed structure.
14. The method of claim 7 wherein said uncompressed structure is compressed to a thickness of from about 80% to about 90% of the original thickness of said uncompressed structure.
15. A process for forming a compressed paper-based web, said process comprising the steps of:
a) forming an original paper-based web; and b) compressing said paper-based web by applying pressure to said web to form a compressed paper-based web, said pressure being sufficient to reduce the thickness of said original paper-based web to a caliper that is from 50% to about 90% of the original caliper of said original paper-based web.
a) forming an original paper-based web; and b) compressing said paper-based web by applying pressure to said web to form a compressed paper-based web, said pressure being sufficient to reduce the thickness of said original paper-based web to a caliper that is from 50% to about 90% of the original caliper of said original paper-based web.
16. The process of claim 15 wherein said original paper-based web is formed by a heavy wet creping paper-forming process.
17. The process of claim 15 wherein said original paper-based web is formed by an uncreped through-air drying paper-forming process.
18. The process of claim 15 wherein said original paper-based web is formed by a light dry creped paper-forming process.
19. An absorbent paper product comprising a compressed paper-based web, wherein said compressed paper-based web has been compressed from an uncompressed paper-based web so as to have its caliper reduced from an original caliper, said reduced caliper being from 50% to about 90% of said original caliper, said compressed paper-based web has a water absorbent capacity of at least about 70% of the water absorbent capacity of said uncompressed paper-based web.
20. The product of claim 19, wherein said compressed paper based web has a water absorbent capacity of at least about 80% of the water absorbent capacity of said uncompressed paper-based web.
21. The product of claim 19, wherein said compressed paper-based web has a water absorbent capacity of at least about 90% of the water absorbent capacity of said uncompressed paper-based web.
