Fabric for electric-arc protective clothing, and electric-arc protective clothing
A fabric for arc-protective garments includes first yarns and second yarns different from the first yarns. The first yarns include first modacrylic fibers, and the first modacrylic fibers contain an infrared absorber in an amount of 2.5 wt % or more with respect to a total weight of the first modacrylic fibers. The weight of the infrared absorber per unit area in the fabric for arc-protective garments is 0.05 oz/yd.sup.2 or more. An arc-protective garment includes the fabric for arc-protective garments.
FLAME-RETARDANT FIBER COMPOSITE AND FLAME-RETARDANT WORKING CLOTHES
A flame-retardant fiber composite includes an acrylic fiber A containing an acrylic copolymer and an aramid fiber. The acrylic fiber A is substantially free of an antimony compound, and the flame-retardant fiber composite forms a surface-foamed char layer when burned. A flame-retardant work clothing includes the flame-retardant acrylic fiber. A highly flame-retardant fiber composite and highly flame-retardant work clothing include an acrylic fiber, and are capable of exhibiting high flame retardancy while suppressing environmental impacts caused by a flame retardant.
FLAME-RETARDANT FABRIC AND PROTECTIVE CLOTHING MADE OF THE SAME
The present invention relates to a flame-retardant fabric that includes modacrylic fibers, one or more of regenerated cellulose fibers selected from the group consisting of flame-retardant rayon fibers and lyocell fibers, and polyimide fibers. The flame-retardant fabric includes the modacrylic fibers in an amount of 26 to 79 wt%, the regenerated cellulose fibers in an amount of 18 to 48 wt%, and the polyimide fibers in an amount of 3 to 26 wt%. The polyimide fibers have a fiber length of 45 to 127 mm. The char length measured by a flammability test based on GB/T 5455-1997 is 50 mm or less. The present invention also relates to protective clothing made of the flame-retardant fabric. Thus, the present invention provides a flame-retardant fabric whose char length is short in a flammability test and that has favorable flame retardancy, and protective clothing made of the flame-retardant fabric.

Fire resistant garments containing a high lubricity thermal liner
Protective garments are disclosed having an inner lining with high lubricity and high strength characteristics. The inner lining, in one embodiment, contains spun yarns combined with para-aramid multifilament yarns. The spun yarns may also contain flame resistant fibers, such as meta-aramid fibers, FR cellulose fibers, or mixtures thereof. The para-aramid filament yarns provide excellent strength characteristics to the fabric. In addition, in some embodiments, the multifilament yarns may enhance the fire resistant properties of the fabric. In one embodiment, the para-aramid filament yarns may have less than five twists per inch, such as from about 1 twist per inch to about four twists per inch.
