Abstract:
A wound dressing material comprising a solid bioabsorbable substrate dyed with an antioxidant dyestuff. The substrate may comprise collagen, chitosan or oxidized regenerated cellulose, and the dyestuff may for example be an aniline or acridine dye. The material preferably also comprises a silver salt, whereby the dyestuff stabilizes the silver salt. Also provided are methods of making such materials, and wound dressings comprising such materials.

Abstract:
The present invention pertains to a kit of parts for the preparation of a solvent based coating composition, said kit of parts comprising A) at least one toner base comprising an acrylic polyol, a cellulose resin, a polyester polyol, and a pigment, B) at least one connector base comprising at least one resin compatible with the resins mentioned in toner base A), and C) at least one reducer base free of resins and pigments. The coating compositions prepared from the kit of parts of the present invention provide a very flexible application window. Due to a selection of resins, additives, and/or fillers to be used in the connector base (B), the use and properties of the coating composition can be modified.
Abstract:
The present invention relates to a process for the manufacture of short or discontinuous lignocellulosic fibre in combination with synthetic fibre filled thermoplastic composites, in which the process consists of preferably, defiberization and dispersion of the cellulosic fibres in the thermoplastic matrix, further consolidation and dispersion of the blended thermoplastic composition, further blending of the same with inorganic fibres to get the moldable thermoplastic composition and further injection or compression or compression injection molded under high pressure ranging from 100 tones to 1000 tones and a temperature range from 170 to 210 degree centigrade into composite products. The said composites have a tensile strength of at least 75 MPa and a flexural strength of at least 125 MPa. The invention also relates to the use of the said composites in automotive, aerospace, furniture and other structural applications.
Abstract:
An absorbent cellulose material having an application of superabsorbent polymer adhered to the cellulose material. In particular, the cellulose material has an application of pre-superabsorbent polymer adhered to the material, wherein an aqueous solution of pre-superabsorbent polymer is applied to the cellulose material and converted to superabsorbent polymer upon subjected to heat for a sufficient time. The absorbent cellulose material has a fluid retention of greater then 2 g/g.

Abstract:
This invention is directed to advanced hemorrhage control wound dressings, and methods of using and producing same. The subject wound dressing is constructed from a non-mammalian material for control of severe bleeding. The wound dressing for controlling severe bleeding is formed of a biomaterial comprising chitosan, a hydrophilic polymer, a polyacrylic polymer or a combination thereof. The kind of severe, life-threatening bleeding contemplated by this invention is typically of the type not capable of being stanched when a conventional gauze wound dressing is applied with conventional pressure to the subject wound. The wound dressing being capable of substantially stanching the flow of the severe life-threatening bleeding from the wound by adhering to the wound site, to seal the wound, to accelerate blood clot formation at the wound site, to reinforce clot formation at the wound site and prevent bleed out from the wound site, and to substantially prohibit the flow of blood out of the wound site.
