Abstract: A fiber is made with a polybenzimidazole (PBI) polymer with a phosphoric acid pick-up (APU) in the range of 1-25% (PBI-p fiber). The PBI-p fiber may have a LOI ≥50% and/or an initial thermal decomposition temperature in air of ≥555° C. A method of making a phosphonated polybenzimidazole fiber comprises the steps of: spinning an untreated PBI resin into a PBI fiber; treating the PBI fiber with phosphoric acid, and thereby obtaining a PBI fiber with 1-25 wt. % phosphoric acid APU.

Abstract: Exemplary embodiments of the present disclosure provide a system, apparatus, and methods for producing a high-performance camouflage and thermal management composite fabric textile systems. The systems comprise woven and non-woven composite fabrics consisting of layers for thermal and electromagnetic wave propagation as well as human thermal emission control. The systems incorporate thermal plastic insulation, felt insulation, electromagnetic wave absorption materials, electromagnetic wave propagation and thermal emission control elements, and camouflage pigment patterns. Dots containing encapsulated metallic particulates enable omni-spectral electromagnetic wave and thermal radiation signature manipulation and control as well as cost-effective manufacturing. Single blended textile processed via needle punching produces hair/fur-like protrusions made from a multilayer fabric composition having EM wave and thermal radiation control elements. The protrusions subsequently contain EM propagation and thermal emission control elements on their surfaces for omni-spectral camouflage and detection mitigation. The systems expand the options for meeting the demands of today and future stealth missions.

Abstract: A novel wound dressing material is produced by a chemical treatment of animal fibers, particularly, wool, to strip off the keratin layers of the surfaces of the fibers so as to expose the non-keratin protein in the underlayers, which is hydrophilic. The wound dressing material provides healing and regenerating effects on the wounds, and can be produced at a low cost.
