    摘要: A method for rendering a carboxyl-containing polymer surface resistant to microbial growth, the method comprising: (i) reacting the carboxyl-containing polymer surface with a metal borohydride in a solvent system comprising a water-soluble alcohol having one to three hydroxy groups and one to four carbon atoms, and optionally up to about fifty percent water, in a temperature range having a minimum of about 60° C. and a maximum of about 80° C., and for an amount of time sufficient for reducing carboxyl groups on the carboxyl-containing polymer surface to surface hydroxymethyl groups without altering the nature of the bulk of the polymer; and either: (iia) converting hydroxy groups of the surface hydroxymethyl groups to leaving groups and displacing the leaving groups with one or a combination of antimicrobial agents; or (iib) displacing the hydrogen atoms of the hydroxy groups of the surface hydroxymethyl groups with one or a combination of antimicrobial agents.

    摘要: A fabric treatment composition that includes a hydrophobic agent with a melting point or glass transition temperature below 100° C. and optionally, a fluoropolymer, that imparts fabric protection benefits, including improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better handfeel to treated fabrics. Compositions may further include a zeta potential modifier in an amount sufficient to adjust the zeta potential of the composition to be positive and greater, than zero millivolts. The composition can be used as a pretreatment prior to drying or ironing, through soaking or direct spray application, or used prior to or during the drying cycle of an automatic drying machine or clothing refresher machine, or used prior to or in conjunction with an ironing device. The fabric treatment is complete when the fabric treated by contact with the protective composition is then cured by drying and/or heating. The invention further includes a kit providing a means for convenient dispensing of the protective composition to effect treatment and curing of fabric articles.
