A system for the functionalization of polyolefin fiber includes a reactor chamber, a fiber pulley system, and a precursor sprinkler system. The reactor chamber defines an interior reactor space and a plurality of fiber inlet/outlet pairs positioned at opposite ends of respective fiber processing axes. The fiber pulley system is arranged to direct polyolefin fiber through the plurality of fiber inlet/outlet pairs, along a fiber processing path comprising the respective fiber processing axes. The precursor sprinkler system is operable to aerosolize a precursor solution and contact the aerosolized precursor solution with the polyolefin fiber. A method for functionalizing polyolefin fiber includes aerosolizing the precursor solution to form an aerosolized precursor solution, passing polyolefin fiber along the fiber pulley system into the reactor chamber, contacting the polyolefin fiber with the aerosolized precursor solution, and passing functionalized polyolefin fiber out of the interior reactor space of the reactor chamber.

The application relates to a process for producing fibrous material with antimicrobial properties, wherein in the first step coniferous resin acid composition is emulsified into aqueous solution with emulsifier and wetting agent, and in the second step thus formed emulsion is transferred into fibrous material by impregnation. Further, the application relates to an aqueous antimicrobial composition for use as a water-soluble concentrate in the treatment of fibrous materials, and to a fibrous material with antimicrobial properties, and to its use in e.g. fabrics, fur, leather, clothes, canvas, tissues, plastics, webs, accessories, packaging materials, wallpapers, food-related products, household products, footwear, construction materials, insulating materials and medical products.

Processes for preparing ultra-high molecular weight polyethylene yarns, and the yarns and articles produced therefrom. The surfaces of partially oriented yarns are subjected to a treatment that enhances the surface energy at the fiber surfaces and are coated with a protective coating immediately after the treatment to increase the shelf life of the treatment. The coated, treated yarns are then post drawn to form highly oriented yarns.
