    • A method of preparing a silver loaded activated carbon fiber includes the following steps. A viscose fiber is treated with a hydroxyalkyl cyclodextrin aqueous solution to obtain a hydroxyalkyl cyclodextrin loaded viscose fiber. The hydroxyalkyl cyclodextrin loaded viscose fiber is then treated with a silver salt aqueous solution to obtain a hydroxyalkyl cyclodextrin and silver salt loaded viscose fiber. The hydroxyalkylated cyclodextrin and silver salt loaded viscose fiber is heated in deionized water at 80 to 100° C. to obtain a silver loaded viscose fiber. The silver loaded viscose fiber is treated with a disodium hydrogen phosphate aqueous solution and then heated under nitrogen at 400 to 600° C. to obtain a silver loaded carbon fiber. The silver loaded carbon fiber is heated under nitrogen and water vapor at 900 to 1,200° C. to obtain the silver loaded activated carbon fiber.
    • 制备负载银的活性炭纤维的方法包括以下步骤。 用羟烷基环糊精水溶液处理粘胶纤维,得到负载粘羟基烷基环糊精的粘胶纤维。 然后用银盐水溶液处理载有羟烷基环糊精的粘胶纤维,得到羟烷基环糊精和负载银盐的粘胶纤维。 将羟烷基化环糊精和负载银盐的粘胶纤维在去离子水中在80至100℃下加热,得到负载银的粘胶纤维。 将银负载的粘胶纤维用磷酸氢二钠水溶液处理,然后在氮气下在400〜600℃加热,得到负载银的碳纤维。 将负载银的碳纤维在氮气和水蒸气下在900-1200℃下加热,得到负载银的活性炭纤维。

    • 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.
    • 提供了具有局部施加的银离子处理(例如离子交换化合物,如磷酸锆,玻璃和/或沸石)的织物的洗涤耐久性和变色水平的改善。 这种固体化合物通常易于变色,并且由于其固体特性通常易于从局部表面应用中去除。 本发明的处理需要特定的聚氨酯粘合剂的存在,作为银离子外涂层或与银离子抗微生物化合物混合的染浴混合物的组分。 此外,使用特定的金属卤化物添加剂(优选基本上不含钠离子)来抵抗典型的这种银离子制剂的变色。 结果,洗涤耐久性,变色水平或两者都可以改善到在大量标准洗涤和干燥之后,本发明的处理不会以任何明显的量磨损,并且处理的颜色基本上保持不变 与第一次应用时相同。 特定的处理方法以及经处理的织物也包括在本发明中。
