A method of producing an absorbent biocompatible material which comprises mixing at least one mycological material, such as a fungus or fungal tissue, with at least one lignocellulosic material to provide a biocomposite material comprising the at least one mycological material and the at least one lignocellulosic material. The biocomposite material then is contacted with at least one substance that increases the hydrophilicity of the biocomposite material, thereby providing an absorbent biocomposite material that has a variety of uses, such as absorbent materials for use in vegetation propagation and preservation, animal bedding, animal litter, filler in diapers, cold chain materials for temperature regulation, ice packs, absorbent foams and mats Bio Basic Absorbent Booms, such as decorative floral arrangement foams, carpet mats, and absorbent booms applied to chemical spills.
Sorbent articles
A microfibrous sorbent article is provided. The microfibrous sorbent article comprises an elongate boom having a substantially oval cross-section. The boom is formed of multiple adjacent microfibers layers, the layers being bonded to each other by entanglement of fibers between adjacent layers. The boom further contains ion exchange resin, selectively absorbent particulate material, catalytic agent, or selectively reactive particulate material.
Biodegradable bait station for liquid ant bait
A biodegradable bait station is disclosed that can be used with liquid baits targeting pest ants in urban, agricultural, and natural setting, which can overcome several limitations that most of other liquid bait stations currently experience. For example, instead of keeping a large quantity of liquid bait in a reservoir, a small amount, for example, 10-20 ml of sugary liquid bait with an insecticide, for example, boric acid, thiamethoxam, imidacloprid, will be contained in a biodegradable cylindrical container with one open end.
The open end will be plugged with a piece of water absorbent polymer or gel, for example, polyacrylamide gel, sodium alginate. The water absorbent polymer or gel absorbs the liquid bait and expands inside of the cylindrical container so that it will function as a polymer “wick” to deliver a small amount of the liquid bait to foraging ants.

A process for making an absorbent towel paper web is provided. The process steps include a) providing a papermaking furnish, b) forming a differential density wet fibrous web from the paper making furnish; and, c) drying the differential density wet fibrous web until fibrous web contains not more than about 10% by weight moisture to form the absorbent towel paper web. Step a) provides the steps of providing: i) from about 20.1% to about 99.9% by weight of a softwood pulp fiber mixture and, ii) from greater than 0% to about 79.9% by weight of a hardwood pulp fiber mixture. Step i) further provides the steps of providing u) from about 20% to about 99.8% by weight of softwood pulp fiber, v) from about 0.05% to about 20% by weight of cellulose nano-filaments, and, w) from about 0.05% to about 5.0% by weight of strengthening additive.
Absorbent sheet made by creping a nascent web on a multilayer belt having openings
An absorbent sheet made by a process that includes the steps of forming a nascent web from an aqueous papermaking furnish, and creping the nascent web on a multilayer belt that includes (i) a first layer made from a polymeric material having a plurality of openings, and (ii) a second layer attached to the first layer, with the nascent web being deposited onto a surface of the first layer.
The absorbent sheet includes a plurality of hollow domed regions projecting from a side of the absorbent sheet, with each of the hollow domed regions being shaped such that a distance from at least one first point on an edge of a hollow domed region to a second point on an edge at an opposite side of the hollow domed region is at least about 0.5 mm.
Absorbent core, articles comprising said core, and methods of making
An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.
Absorbent article with partial laminate waist elastic member
An absorbent article (10) can include a waist elastic member (50, 150, 250). In one embodiment, the waist elastic member (50, 150, 250) can include a first longitudinal zone (92), a second longitudinal zone (94), and a middle longitudinal zone (93). The first longitudinal zone (92) can include a first elastic member (76) disposed between two layers of material, the second longitudinal zone (94) can include a second elastic member (78) disposed between two layers of material, and the middle longitudinal zone (93) can include less layers of materials than each of the first longitudinal zone (92) and the second longitudinal zone (94).
Polymer-based superabsorbent coating composition and use thereof
The present invention relates to a polymer-based superabsorbent coating composition and a use thereof. The superabsorbent coating composition comprises: (i) an absorbent material; and (ii) a binder comprising a polymerizable absorbent polymer and a crosslinking agent, wherein the absorbent material contains at least one functional group for chemically binding to the binder, thereby chemically bonding to the binder, and the absorbent polymer and the crosslinking agent chemically bond together within the binder.
Absorbent towel products comprising nanofilaments
A differential density absorbent towel paper web having from about 45% to about 90% by weight of the dry fiber basis of the differential density absorbent towel paper web of a softwood pulp fiber mixture and from about 10% to about 55% by weight of the dry fiber basis of the differential density absorbent towel paper web of a hardwood pulp fiber mixture is provided.
The softwood pulp fiber mixture has: 1) from about 20.0% to about 88.5% by weight of the dry fiber basis of softwood pulp fiber; and, 2) from about 0.05% to about 5.0% by weight of the dry fiber basis of strengthening additive. The hardwood pulp fiber mixture has: 1) from about 9.9% to about 54.9% by weight of the dry fiber basis of hardwood pulp fibers; and, 2) from about 0.05% to about 20.0% by weight of the dry fiber basis of cellulose nano-filaments.
Absorbent article with fusion bonded side seams
A pull-on diaper 50B of the invention includes an outer cover assembly 3 defining the exterior surface of the diaper. A front body portion F and a rear body portion R of the outer cover assembly 3 are connected to each other along their laterally opposite side edges to form a pair of side seams 4, a waist opening 8, and a pair of leg openings 9. Each side seam 4 has a sealed edge portion 41 where the front body portion side edge 3F and the rear body portion side edge 3R of the outer cover assembly 3 are bonded to each other at a continuous linear fusion bond extending in the longitudinal direction of the side seam and, in part, a non-sealed portion 42 where the front body portion side edge 3F and the rear body portion side edge 3R of the outer cover assembly face to each other in a non-bonded relationship.
