Title:
低下した変色傾向を示す部分的に適用された銀系仕上げ剤を有する布地
Document Type and Number:
Japanese Patent JP4551770
Kind Code:
B2
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.
