    摘要： A yarn, fabric, and garment suitable for use in arc and flame protection and having improved flash fire protection consisting essentially of from (a) 50 to 80 weight percent meta-aramid fiber having a degree of crystallinity of at least 20%, (b) 10 to 30 weight percent flame-retardant rayon fiber, (c) 10 to 20 weight percent modacrylic fiber, (d) 0 to 5 weight percent para-aramid fiber, and (e) 0 to 3 weight percent antistatic fiber based on the total weight of components (a), (b), (c), (d), and (e). In one embodiment, garments made from the yarn provide thermal protection such that a wearer would experience less than a 65 percent predicted body burn when exposed to a flash fire exposure of 4 seconds per ASTM F1930, while maintaining a Category 2 arc rating.

    摘要： A ply-twisted yarn useful in cut resistant fabrics is made by providing a first multifilament yarn of continuous organic filaments having a tensile strength of at least 4 grams per denier and having a twist in a first direction of from 0.5 to 10 turns per inch; providing a second yarn comprising 1 to 5 continuous inorganic filament(s); and ply-twisting the first yarn and the second yarn about each other 2 to 15 turns per inch in a second direction opposite to that of the twist in the first yarn to form a ply-twisted yarn having an overall effective twist of +/- 5 turns per inch.
