    摘要： An oxidizing anti-microbial treatment and products containing such treatment are described. The treatment involves, in part, preparing a substrate to accept an attachment of charged moieties, and a number of stabilized peroxide compounds on at least part of a surface of said substrate. When microbes, such as bacteria, having a net charge opposite to that of the charged moieties come in close proximity to the treated substrate surface, peroxide molecules from the substrate are activated and released to kill the microbes.

    摘要： As described herein, an abrasion resistant nonwoven fabric includes fibers having an external surface covered with a treatment selected from the group consisting of organosilicone compounds applied by plasma treatment in inert gas without the presence of oxygen and acrylic monomers having a Tg greater than or equal to 20 degrees C. applied onto the nonwoven fabric and subsequently surface grafted and crosslinked via exposure to plasma glow discharge or e-beam without the presence of oxygen. The treated fabrics demonstrate improved abrasion resistance over untreated fabrics.

    摘要： A technique for incorporating a liquid additive into a nonwoven web is disclosed. Specifically, the liquid additive is loaded into filler particles to form a “dry liquid concentrate”, i.e., pulverulent granular solid or powder loaded with the liquid additive. The incorporation of the liquid additive into dry liquid concentrates provides a variety of benefits. For example, prior to extrusion, the dry liquid concentrates generally retain the properties of filler particles from which they are formed as the liquid remains isolated. In this manner, a higher level of the liquid additive may be compounded with a melt-extrudable base composition without adversely affecting the extrusion process. Only upon extrusion of the composition will a significant portion of the liquid additive be released to provide the desired properties to the resulting nonwoven web.

    摘要： An antimicrobial composition that involves a synergistic mixture in terms of active agents, of a primary antimicrobial agent, such as polyhexamethylene biguanide (PHMB), a secondary antimicrobial agent, and optionally an organic acid against various kinds of microbes is described. Various additional processing aids, such as alcohols and surfactants, may also be incorporated within the mixture. The composition allows one to use a significantly less concentration of individual constituent antimicrobial agents to achieve the same or a better degree of antimicrobial efficacy. The antimicrobial composition can be applied to the surface of almost any kind of substrate material, and can achieve a killing-efficacy of about 3 Log10 reduction in microbes within 30 minutes under ambient conditions.
