A method is provided to form a barrier configured to be placed between a first region and a second region, to prevent passage of pathogens between the first region and the second region. The method includes melt blowing a stream of polymer fibers onto a surface to form a non-woven fabric used to make the barrier. The melt blowing includes introducing pathogenicidal components into the stream of polymer fibers. A device of a system is also provided to form the barrier according to the method disclosed herein. The device is configured to introduce pathogenicidal components into the stream of polymer fibers downstream of the extruder and upstream of the collector.

Some embodiments include a method of preparing polymer nanofiber composites using a cross-linkable polymer precursor solvated with a solvent, and forming a nanofiber precursor by mixing with a metal-organic-framework (MOF) crystal material that includes a metal ion coupled to at least one multidentate ligand. Further, the method can include forming a plurality of nanofibers by electro-spinning the nanofiber precursor, where at least a portion of the nanofibers includes a dispersion of the first MOF crystal material. The method can include crosslinking the plurality of nanofibers by irradiating the plurality of nanofibers with UV light, IR light, visible light, gamma radiation, and/or electro-beam radiation. Further, the method can include applying a second MOF crystal material between the cross-linked nanofibers and the first MOF material.

The present invention addresses the problem of providing a synthetic fiber first processing agent which improves storage stability. This synthetic fiber first processing agent contains a phosphate compound (A), a solvent (S) and an optional non-ionic surfactant (C), said agent being characterized in that the content ratio of the phosphate compound (A) to the non-ionic surfactant (C) is within a prescribed range, and by being used in conjunction with a synthetic fiber second processing agent which contains a non-ionic surfactant (E). The phosphate compound (A) contains a prescribed organic phosphate ester compound, and the proton NMR integration ratio attributable to an inorganic phosphate compound during proton NMR measurement when performing an alkali over-neutralization preprocessing is set to a prescribed range. The solvent (S) has a boiling point no higher than 105 C. at atmospheric pressure. The non-ionic surfactant (C) has a (poly)oxyalkylene structure in the molecule thereof.

This invention relates to a method for producing a colored yarn based on synthetic fibers, wherein the method comprises the addition of a spinning additive. The spinning additive is self-elutable and/or self-sluicing upon washing the yarn and/or a fabric spun from the yarn with an aqueous solution and/or the spinning additive is water-soluble. The spinning additive can therefore be easily removed from the yarn and/or fabric produced of the yarn by washing with water.
