Abstract
Disclosed is a unitary absorbent structure including a fluid acquisition stratum; a fluid distribution stratum; and a fluid storage stratum between the acquisition stratum and the distribution stratum. Each of the acquisition, distribution, and storage strata are in fluid communication with each other.
Claims57
A unitary absorbent structure comprising:
- a. a fluid acquisition stratum;
- b. a fluid distribution stratum;
- and
- c. a fluid storage stratum between the acquisition stratum and the distribution stratum, wherein the acquisition, distribution, and storage strata are in fluid communication with each other.
A method of forming a multistrata absorbent structure, comprising:
- a. airlaying a 1st batt of fibers to be used in fluid distribution;
- b. airlaying a 2nd batt of fibers and a high absorbency material to be used in fluid storage over the 1st batt of fibers;
- c. airlaying a 3rd batt of fibers to be used in fluid acquisition over the 2nd batt of fibers;
- and
- d. compacting the batts of fibers to form a multistrata absorbent structure comprising a fluid storage stratum between an acquisition stratum and a distribution stratum.
A method of forming a multistrata absorbent structure comprising:
- a. airlaying a 1st batt of fibers to be used in fluid distribution;
- b. airlaying a 2nd batt of fibers and a high absorbency material to be used in fluid storage over the 1st batt of fibers;
- c. airlaying a 3rd batt of fibers comprising cellulosic fibers to be used in fluid acquisition over the 2nd batt of fibers;
- d. airlaying a 4th batt of fibers comprising synthetic fibers to be used in fluid acquisition over the 3rd batt of fibers;
- and
- e. compacting the fibers to form a multistrata absorbent structure comprising from top to bottom an acquisition substratum comprising synthetic fibers, an acquisition substratum comprising cellulosic fibers, a fluid storage stratum, and a fluid distribution stratum.
