  • Flame resistant thermal liner, composite fabric, and garment
    Patent number: 9913504
    Abstract: The present invention relates to a flame resistant thermal liner comprising a nonwoven sheet comprising nanofibers of a synthetic polymer having an limiting oxygen index of at least 21, a mean flow pore of 10 micrometers or less, a thickness air permeability of 25 to 6000 cubic feet per min?micrometers (12 to 2880 cubic meters per square meter per min?micrometers), and an average thickness T1; and a thermally stable flame resistant fabric attached to an outer surface of the nonwoven sheet, the fabric having an average thickness T2; a surface of the thermally stable fabric being in contact with a surface of the nonwoven sheet; wherein T1 and T2 are selected such that the ratio of T1 to T2 is less than 0.75. The invention also relates to a flame resistant composite fabric comprising the flame resistant thermal liner and a garment comprising this flame resistant composite fabric.

  • Thermal liner subassembly, fabric and method of use
    Patent number: 8347420
    Abstract: The present invention concerns a thermal liner sub-assembly comprising crimped, heat resistant fibers held in a state of compression by a binder adhered to at least one thermally stable flame resistant stabilizing fabric wherein, when the thermal liner is exposed to heat or flame, the liner increases its thickness by at least one hundred percent and the shrinkage of the liner is no more than ten percent. The invention also relates to use of such liners in protective fabrics, garments, and articles.
