  • STAPLE FIBERS CONTAINING RELEASABLE SURFACE MODIFYING MOLECULES
    Publication number: 20230142258
    Abstract: Staple fibers and compositions formed from staple fibers are disclosed herein. The fibers are functionalized with molecules that render fabrics comprising the disclosed fibers hydrophobic, hydrophilic, and/or release molecules upon exposure to an external stimulus. Also presented are methods of synthesizing the same and a fabric comprising woven yarns including the staple fiber.

  • POLYMER COMPOSITIONS FOR FLAME RETARDANCY AND/OR IMPROVED MELT DRIPPING PROPERTIES
    Publication number: 20220389220
    Abstract: Compositions with improved flame properties and with improved melt dripping properties can include a first polymer and a reactive component. The first polymer may be nylon or polyethylene terephthalate (PET). The composition can be formed into fibers and woven into a fabric. Crosslinking of the first polymer or of the first polymer and the reactive component can provide the improved properties.
