Abstract
A liquid absorbent composite is disclosed. The composite comprising a first substrate and a laminate or bonded mixture, the laminate or bonded mixture comprising a mixture of binder particles and super-absorbent polymer particles, wherein the binder particles are on average smaller than the super-absorbent polymer particles, wherein at least some of the binder particles coalesce at least some of the bonded mixture to the substrate, wherein at least some of the bonded mixture forms a three-dimensional array of elongated channels upon contact with a liquid.

A composite comprising a first substrate and a bonded mixture, said bonded mixture comprising a mixture of binder particles and super-absorbent polymer particles, wherein said binder particles are on average smaller than said super-absorbent polymer particles, wherein at least some of said binder particles coalesce at least some of said bonded mixture to said substrate, wherein at least some of said bonded mixture forms a three-dimensional array of elongated channels upon contact with a liquid.
A method of absorbing liquid comprising the steps of:
- a) placing a composite adjacent to a liquid source, wherein said composite comprises a first substrate and a bonded mixture, said bonded mixture comprising a mixture of binder particles and super-absorbent polymer particles, wherein said binder particles are on average smaller than said super-absorbent polymer particles, wherein at least some of said binder particles coalesce at least some of said bonded mixture to said substrate, and wherein at least some of said bonded mixture forms a three-dimensional array of elongated channels upon contact with a liquid from said liquid source;
- and
- b) absorbing the liquid by means of at least some of said bonded mixture.
A liquid absorbent pad which comprises:
- an outer layer of a substantially liquid-impervious material having an outer surface and an inner surface;
- at least one composite segment positioned on said inner surface of said liquid impervious material, said at least one composite segment comprising a first substrate and a bonded mixture, said bonded mixture comprising a mixture of binder particles and super-absorbent polymer particles, wherein said binder particles are on average smaller than said super-absorbent polymer particles, wherein at least some of said binder particles coalesce at least some of said bonded mixture to said substrate, and wherein at least some of said bonded mixture forms a three-dimensional array of elongated channels upon contact with a liquid;
- and
- a liquid-permeable acquisition layer in liquid communication with said at least one composite segment, wherein at least a portion of said outer layer and said liquid permeable acquisition layer are directly or indirectly attached, and said at least one composite segment is sandwiched therebetween.
