US Classification:

427475, 427485, 427201, 427202, 4273899

Abstract:

The invention provides processes for coating the surface of substrates such as a sheet, film, foam, fiber, etc. , with a curable liquid resin or solution of curable resin, then in one embodiment, stably attaching a superabsorbent polymeric powder to such resin, and then curing the resin to form a coated superabsorbent product. Such substrates may include polymeric materials. Other process embodiments utilizing curable and thermoplastic resinous powders may be used instead of curable liquid resins and resulting products are included in the invention. The coated product has reduced particle agglomeration and particle loss due to the curing or melting steps. The thin, superabsorbent powder adhered, films may be used as an absorbent core for a wide variety of absorbent products. The product can be interposed between sheets to form disposable absorbent products such as diapers, bandages, water and nutrient retention elements, erosion control devices and elements thereof, etc. or used on one side to form cleaning products.

Abstract:

The invention provides processes for coating the surface of substrates such as a sheet, film, foam, fiber, etc. , with a curable liquid resin or solution of curable resin, then in one embodiment, stably attaching a superabsorbent polymeric powder to such resin, and then curing the resin to form a coated superabsorbent product. Such substrates may include polymeric materials. Other process embodiments utilizing curable and thermoplastic resinous powders may be used instead of curable liquid resins and resulting products are included in the invention. Other embodiments involve affixing a container at least partially filled with superabsorbent polymeric powder to a substrate, placing the container proximate to the element, or affixing the container to a separate member. The products may be utilized for water and nutrient retention in combination with irrigation, erosion control, to direct plant root growth, and to clean up standing water and petroleum spills.

International Classification:

A61F 13/53

US Classification:

604367, 604378

Abstract:

A method of making a pouch-like container product for absorbing liquids comprises joining a first sheet having SAP particles preferably adhered to a first surface with a second sheet to form a container partially filled with such particles. The application of pressure, for example by passing the product through a roll nip, facilitates joining of the sheets and causes the particles to break through at least the one of the sheets to create an opening whereby free volume is created to permit the particles to expand when in contact with a liquid. The resultant product is also described. In an additional product embodiment non-SAP particles may be utilized to break through the sheet(s) and preformed openings may also be included in the sheet(s). Additional SAP material may be placed in between the sheets of the product.

Abstract:

A method of underground watering utilizes a pouch-like container product made by joining a first sheet having SAP particles adhered to a first surface with a second sheet to form a container partially filled with such particles. The application of pressure, for example by passing the product through a roll nip, facilitates joining of the sheets and causes the particles to break through at least the one of the sheets to create an opening whereby free volume is created to permit the particles to expand when in contact with a liquid. The resultant product is used to collect, store, and dispense water-containing liquids into the soil for watering of agricultural plants, trees, and the like. A composite underground watering element is also included in an embodiment of the invention. The inventive products may also be used as a pad, including a propagation pad, to collect, store, and dispense water-containing-liquids into plant vessels to provide watering of plants. Also included are underground watering of athletic fields and golf course greens, erosion control products and plant root balls having a watering collar.
