The present invention provides agents having efficacy against viruses, allergens, bacteria and odorants, materials including such agents, and methods for producing the agents. An agent according to an embodiment of the present invention includes titanium dioxide particles having low photocatalytic activity, and metal ions of at least one metal selected from gold, silver, platinum and copper that are adsorbed to the surface of the titanium dioxide particles. The agent may further include hydroxyapatite particles, and the metal ions may be adsorbed also to the surface of the hydroxyapatite. The metal ions may be at least partially present in the form of at least one of an oxide of the metal, a hydroxide of the metal, and the elemental metal.

There is disclosed a method of coating textile fibers, the method comprising applying, on the external surface of textile fibers, a pre-treated oil-in-water emulsion comprising: (i) an aqueous phase containing water; and (ii) a pre-treated oil phase containing at least one reactive condensation-curable film-forming amino-silicone pre-polymer that, subsequent to condensation curing optionally in presence of additional reactants, forms an amino-silicone coat. The pre-treated reactive oil phase includes at least one pre-treated reactant or pre-treated pre-polymer. An aqueous dispersion containing particles of a hydrophilic polymeric material is then applied to the amino-silicone coat, so as to form a polymeric layer thereon. At least one of the oil-in-water emulsion forming a first coat and of the aqueous dispersion forming a second coat may further contain a plurality of sub-micronic pigment particles dispersed therein. Suitable compositions and kits including the same are also disclosed, as well as fibers coated thereby.

This document presents algae-derived antimicrobial fiber substrates, and a method of making the same. The fiber may be a synthetic fiber, but can also be formed as a cellulosic (e.g., cotton). In various implementations, an algae-derived antimicrobial fiber substrate can be made to have identical properties and characteristics of nylon-6 of nylon 6-6 polymer or the like, and yet contain antimicrobial, anti-viral, and/or flame retardant algal derived substances. Any of various species of red algae, brown algae, blue-green algae, and brown seaweed (marine microalgae and/or macroalgae) are known to contain a high level of sulfated polysaccharides with inherent antimicrobial, antiviral, and flame-retardant properties, and can be used as described herein. Additionally disclosed are algae-derived flexible foams, whether open-cell or closed-cell, with inherent antimicrobial, antiviral, and flame resistant properties. Further, a process of manufacturing is presented wherein the process may include one or more of the steps of: harvesting algae-biomass; sufficiently drying the algae biomass; blending the dried algae biomass with a carrier resin and various foaming ingredients; adding an algal-derived antimicrobial compound selected from various natural sulfated polysaccharides present in brown algae, red algae, and/or certain seaweeds (marine microalgae); and adding a sufficient quantity of dried algae biomass to the formulation to adequately create a fire resistant flexible foam material.
