|1. (WO2018184051) A NONWOVEN MATERIAL DESIGNED FOR USE IN ABSORBENT CORE STRUCTURES WITH INTRINSIC ACQUISTION/DISTRIBUTION CAPABILITIES|
HAYHURST, Malcolm, John
|Title:||A NONWOVEN MATERIAL DESIGNED FOR USE IN ABSORBENT CORE STRUCTURES WITH INTRINSIC ACQUISTION/DISTRIBUTION CAPABILITIES|
This invention relates to an absorbent core structure comprising: (a) an essentially pure cellulose nonwoven web formed from essentially continuous filaments and multibonded by merged filaments, hydrogen bonding and/or physical intermingling of filaments, and (b) combined with superabsorbent polymer, for use in hygiene products. This product is thin, lightweight and flexible and has high wet and dry strength, excellent absorbency and retention, and maintains the superabsorbent polymer in its designed location, both dry and when wet and swollen. It further relates to the use of the inventive absorbent core structure according for the manufacture of a hygiene product. Further it relates to a hygiene product characterized in that it contains the inventive absorbent core structure, the use of the inventive absorbent core structure where it is combined with another nonwoven material to produce a nonwoven composite for hygiene applications and the use of the inventive absorbent core structure to provide the functions of acquisition/distribution layer, a core wrap and an absorbent core in a single hygiene product and/or structure.
