    • There is provided products for the removal of negatively charged particles like bacteria from surfaces. The products have a positive charge that may be developed through the use of cationic treatments. The product or substrate from which it is made may be dipped in an aqueous solution of a non-antimicrobial treatment having a positive charge and the excess solution squeezed out. Treatment of the resulting coated substrate with heat at a temperature and for a time sufficient adheres the coating to the substrate. Alternatively, a non-antimicrobial, cationically charged chemical may be imbedded in a substrate web such that it will bloom to the surface when the web is exposed to water. A suitable substrate web may be a pulp and synthetic fiber fabric made by coforming or hydroengling and may be a laminate including other layers. The treated substrate and product remove a substantial amount of the bacteria from a surface yet do not appreciably kill the bacteria. Harsh, oxidizing, chemicals are not used in the preparation of the products and so the products are mild in their effect on the user's skin. The removal of the bacteria, in contrast to killing the bacteria, does not encourage the bacteria to develop immunity to the treatment.
    • 提供了从表面除去带负电荷的颗粒如细菌的产品。 这些产品具有通过使用阳离子处理可以开发的正电荷。 可以将其制成的产品或基材浸渍在具有正电荷且过量溶液挤出的非抗微生物处理的水溶液中。 在一段温度和一段时间内用热量处理所得的涂覆的基材足以将涂层粘附到基材上。 或者,非抗微生物的带阳离子电荷的化学品可以嵌入基材网中,使得当幅材暴露于水时,其将盛开到表面。 合适的基材纤维网可以是通过共成型或水化加工制成的纸浆和合成纤维织物,并且可以是包括其它层的层压体。 经处理的底物和产物从表面除去大量的细菌,但不会明显杀死细菌。 苛刻,氧化,化学品不用于制备产品,因此产品对用户皮肤的影响温和。 与杀死细菌相反,细菌的去除不会鼓励细菌发挥对治疗的免疫力。
