摘要:
The present invention is directed to a textile material to which one or more antimicrobial and/or hydrophilic and/or stain release agents are adhered. The agent(s) is/are adhered to the textile material in such a manner that they are not released from the textile even if the textile is wetted or washed, so that the textile is reusable. In preferred embodiments, where one or more antimicrobial agents are adhered to the textile, the textile can be used to sanitize a surface in a non-leaching manner, e.g. without a liquid sanitizer, both under wet and dry conditions. Washability and/or usability of the textile are improved where one or more hydrophilic and/or stain release agents are adhered to the textile, which is particularly advantageous if the textile is used as a wipe or for similar purposes. The invention further relates to a method of finishing a textile material by applying and binding antimicrobial and/or hydrophilic and/or stain release agents to the textile material so that the agents are essentially irreversibly adhered to the finished textile material.

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.

A process is described for manufacturing a hydrophilic and wash durable textile material which exhibits a high antimicrobial efficacy and a high stain release capability. The process comprises an antimicrobial process cycle and a main process cycle, the antimicrobial process cycle being performed before the main process cycle. The antimicrobial process cycle comprises the steps of treating the textile material using an exhaust or padding process, wherein the liquor comprises one or more chemical agents which increase the antimicrobial efficacy of the textile material, and subjecting the treated textile material to a heat treatment. The main process cycle comprises the steps of treating the textile material using an application process such as a knife or screen coating process, a spraying process, an exhaust process, or preferably a padding process, wherein a liquor is applied to the textile which comprises one or more chemical agents which increase the stain release capability of the textile material, and subjecting the treated textile material to a heat treatment. The resulting textile material is particularly suitable for forming an absorption layer in a reusable sanitary napkin.

The present disclosure provides low pH fibers that are treated with additives, preferably after regenerating the cellulosic fiber, to control the pH and oxidation-reduction potential (ORP) in an aqueous environment where the fiber is placed. The low pH fibers can be formed into fibrous articles such as tampons or wipes. The low pH fibers with the additives provide health benefits to the user in that they hinder the ability of harmful bacteria to flourish.

The present invention relates to a tapered filament prepared from bio-based biologic-based material and a method for producing same. The present invention generally provides a method for producing a tapered filament, comprising the following steps of: a) providing filaments; b) providing a treating solution to treating tank; c) immersing the filaments in step a) into the treating solution, using auxiliary means such as mechanical stirring and/or cycling, or ultrasound energy for treating agent for enhancing effects of tapering, in which during step c), the depth of the filaments immersed in the treating agent varies with time.
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.
