摘要:
This invention provides a silver ion coated product, such as a denture and a restoration object for body deficiency, which can realize an antimicrobial coating capable of exhibiting persistent antimicrobial properties, antifouling properties, and deodorant properties. Silver ions are coated onto a target object (3) by microwave irradiation in such a state that the target object (3) is immersed in a container (2) containing an silver ion solution (1), or the target object (3) has been spray coated by a sprayer (12) containing the silver ion solution (1). Previous plasma ion coating onto the target object is also preferred. For example, silver ion coating treatment of the target object subjected to DLC coating is carried out.

The invention concerns a polymeric antimicrobial composition, a method of producing the same and the uses thereof. The ionomer composition comprises an amine functional polymer compound reacted with silver halide, optionally together with a stabilizing component, such as an organic substance carrying a sulfonamide functional group. The ionomer composition can be obtained by reacting together (i) at least one polyamine and silver halide and optionally at least one organic stabilizer substance or; (ii) at least one polyamine, at least one non-halide silver salt or silver complex, hydrogen halide and/or alkaline metal halide salt and optionally at least one organic stabilizer substance. The present ionomer composition is suitable for use as an antimicrobial coating, antimicrobial finish, antimicrobial additive and as antimicrobial component for formation of new antimicrobial materials.

The present invention relates to metal coated nano-fibres obtained by a process that includes electrospinning and to the use of said metal coated nano-fibres. The process is characterised in that a polymer nano-fibre with functional groups providing the binding ability to a reducing reagent is prepared by electrospinning at ambient conditions. Then this is contacted with a reducing agent, thereby opening the epoxy ring on the surface of polymer nano-fibre and replacing with the reducing agent and the reducing agent modified film is reacted with metal solution in alkaline media. Finally the electrospun mat is treated with water to open the epoxy rings in the structure and crosslinking the chains to provide integrity.
摘要:
Improvements in the wash durability and discoloration levels for fabrics having topically applied silver-ion treatments (such as ion-exchange compounds, like zirconium phosphates, glasses and/or zeolites) are provided. Such solid compounds are generally susceptible to discoloration and, due to the solid nature thereof, are typically easy to remove from topical surface applications. The inventive treatment requires the presence of a specific polyurethane binder, either as a silver-ion overcoat or as a component of a dye bath mixture admixed with the silver-ion antimicrobial compound. In addition, specific metal halide additives (preferably substantially free from sodium ions) are utilized to combat the discolorations typical of such silver-ion formulations. As a result, wash durability, discoloration levels, or both, can be improved to the extent that after a substantial number of standard launderings and dryings, the inventive treatment does not wear away in any appreciable amount and the color of the treatment remains substantially the same as when first applied. The particular treatment method as well as the treated fabrics are also encompassed within this invention.

In a preferred embodiment, the present process involves subjecting a fabric comprised of conjugate yarns to an acidic treatment, which degrades a portion of one component of the conjugate yarns and to dyeing. The acid treatment, given certain reaction kinetics, removes a portion of the polyamide element of the conjugate filament. The at least partial removal of the polyamide component results in a fabric has enhanced dyed appearance, especially when dyed a dark shade. In an alternate embodiment, the fabric may also be treated with a basic solution to improve its moisture transport properties.
