Abstract:
1. An electrospun functionally active nanofiber comprising: a homogenous mixture of one or more polymer and one or more bleaching agent, wherein said polymer and said bleaching agent are at least partially reacted or bonded together, said polymer is at least partially water-soluble, at least partially ethanol-soluble, at least partially glycerol-soluble, or combinations thereof, said bleaching agent is selected from the group consisting of peracids, perborates, percarbonates, sodium hypochlorite, calcium hypochlorite, peroxides, or mixtures thereof, optionally, said mixture includes one or more additives, anti-corrosion materials, anti-redeposition materials, anti-static agents, anti-sticking agents, buffering and pH adjusting agents, chelating agents, defoamers, elastomers, enzymes, filler materials, foamers, fragrances or perfumes, heat generating materials, hydrotropes, sequestration agents, softening agents, soil release agents, solubilizing materials, stabilizers, surfactants, sudsing control agents, thickeners, solvents, wetting agents, and-UV protectors, said mixture having a viscosity of said mixture about 1000-10000 cps at 20° C., said mixture of one or more polymer, one or more bleaching agent and one or more additives, together forms a homogenous composition that is formed into a homogenous nanofiber that has an average diameter of less than about 1000 nanometers, said polymer designed to dissolve in water at a slower rate than said bleaching agent so as to extend the time of release of said bleaching agent from said polymer and thereby extend cleaning time and efficacy of said electrospun functionally active nanofiber.
