Abstract
A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.
Claims8
A disposable absorbent article comprising:
- a. a topsheet,
- b. a backsheet, and
- c. an absorbent composite comprising
- i. a first fabric that is in addition to and between the topsheet and the backsheet,
- ii. a second fabric bonded to said first fabric,
- iii. an absorbent layer of particles adhered between said first and second fabric,
- wherein said absorbent composite is disposed between the topsheet and backsheet, and generally centrally at a location identified as a crotch region, and
- wherein the absorbent composite lacks an absorbent matrix capable of stabilizing the absorbent layer of particles against particle migration.
A disposable absorbent article comprising:
- d. a topsheet,
- e. a backsheet, and
- f. an absorbent composite consisting of
- i. a first fabric that is in addition to and between the topsheet and the backsheet,
- ii. a second fabric bonded to the first fabric,
- iii. an absorbent layer of particles
- 1. adhered between the first and the second fabric by an adhesive in sufficient quantity to inhibit migration of the particles and in a concentration of 1 to 100 grams per square meter, and
- 2. having a concentration of absorbent particles of 50 to 650 grams per square meter,
- iv. optionally, a plurality of discrete points or bond lines joining the first fabric to the second fabric at to define pockets for further inhibiting migration of the absorbent particles, and
- v. optionally, one or more of absorbent particles coated with mineral oil, skin care particles, odor absorbing particles, binder particles, ion exchange resins or particles, or any combinations of the foregoing,
- wherein said absorbent composite is disposed between the topsheet and backsheet, and generally centrally at a location identified as a crotch region.
