Abstract:
Improvements in the high-temperature 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, particularly when laundered at elevated temperatures. The inventive treatment requires the presence of a specific cross-linked binder, either as a silver-ion overcoat or as a padded-on component of a cross-linked binder admixed with the silver-ion antimicrobial compound. In addition, specific metal halide additives (preferably substantially free from sodium ions) may be utilized to combat the discolorations typical of such silver-ion formulations. As a result, high-temperature 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.

Abstract:
Wound care devices having a topically applied silver-based antimicrobial finish are provided. The finish comprises at least one silver ion-containing compound and at least one binder compound. The finish may be applied to a target substrate, such as a fiber, fabric, film, foam, hydrogel, or hydrocolloid to provide a single layer antimicrobial wound care device. Alternatively, a silver-containing layer may be combined with one or more additional layers of target substrate to provide a composite antimicrobial wound care device. The device may also contain an odor-absorbing component capable of reducing or eliminating odors that are inherently associated with infectious wounds. Also provided is a method for making the wound care device and a composition of matter comprising the silver-based antimicrobial finish.

Abstract:
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.

Nonwoven Roll Towels Having Antimicrobial Characteristics

International Classification:

US Classification:
442/117000, 442/110000, 442/408000, 442/394000
Abstract:
The present disclosure relates to roll towels made from a nonwoven fabric and treated with a silver-ion containing compound to impart antimicrobial characteristics to the fabric. Specifically, the nonwoven fabric of one preferred embodiment is comprised of composite fibers that are at least partially split into their microdenier elementary components. Such structure provides a greater surface area onto which the silver ions may adhere, thus increasing the amount of surface-available silver. This structure further causes the fabric to be highly absorbent, despite being made of synthetic materials.

Abstract:
Antimicrobial fabrics having a topically applied silver-based antimicrobial finish are provided. The finish comprises at least one silver ion-containing compound and at least one binder compound. The antimicrobial fabric may be formed into a garment to be worn as a base layer garment, close to the skin, which aids in the prevention of skin infection caused by abrasions to the skin. The garment may also aid in preventing the transfer of microbes from one person to another, for instance, after sharing communal items such as protective athletic equipment. The antimicrobial fabric exhibits long lasting antimicrobial efficacy against both Gram positive and Gram negative microbes and also exhibits antimicrobial efficacy after repeated wash cycles. Also provided is a method for making the silver-containing antimicrobial fabric.
