Abstract

See full text

A yarn is disclosed, which includes a blend of: 33-75 wt. % of a flame resistant fiber having a limit of oxygen index of 43%, a thermal conductivity of 0.0063 watt/meter/K and a moisture regain of 12%; 10-40 wt. % of an aramid fiber; and up to 36% of a wearability enhancing fiber selected from the group consisting of wool, flame resistant rayon and lyocell, wherein the yarn is free of thermoplastics and is sufficiently flame resistant such that a fabric consisting of the yarn is effective to limit a body burn percentage resulting from 4 seconds of flame exposure to less than 35% as measured by ASTM F1930. Fabrics and garments including the inventive yarn are also disclosed.
