  • Patent number: 11691379
    Abstract: The application relates to a fire-resistant textile composite having an upper surface and a lower surface. The composite contains a nonwoven layer and a knit layer. The nonwoven layer has a first and second side and contains a nonwoven textile. The nonwoven textile contains a plurality of first fire-resistant fibers, where the first fire-resistant fibers are non-thermoplastic. The nonwoven layer forms the lower surface of the textile composite. The knit layer contains a knit textile having a first and second side and the second side of the knit layer is adjacent to the first side of the nonwoven layer. The knit textile contains a plurality of second fire-resistant yarns, where the second fire-resistant yarns are non-thermoplastic. At least a portion of the first fire-resistant fibers from the nonwoven layer extend through the first side of the knit layer and form the upper surface of the textile composite.

  • Patent number: 9982096
    Abstract: A composition comprises at least one condensed phosphorus compound. The condensed phosphorus compound is produced by reacting together in a condensation reaction a nitrogen compound and a phosphonium compound. A phosphorus-containing polymer is produced by reacting in a condensation reaction a hydroxyalkylphosphonium compound to produce an intermediate polymer and then oxidizing phosphorus atoms in the intermediate polymer to yield a polymer comprising phosphine oxide groups.

  • Patent number: 9926663
    Abstract: An article comprises a textile material and a flame retardant, phosphorus-containing polymer. The flame retardant, phosphorus, containing polymer can be present in the form of a plurality of microprotuberances. The flame retardant, phosphorus, containing polymer can contain a relatively low amount of residual hydroxyalkyl groups bonded to the phosphorus atoms in the polymer. A process for producing a treated textile material is also provided.
