Abstract
A yarn, fabric, and apparel formed from modacrylic fibers and high energy absorptive fibers. When the yarn is formed into a fabric comprised substantially of the yarn, the fabric meets the American Society for Testing and Materials standard for flame resistance and the National Fire Protection Association standard for arc thermal performance exposure.
Claims37
A yarn comprising:
- (a) an intimate mixture of modacrylic and high energy absorptive fibers, the modacrylic fibers comprising at least about 70 percent of the fibers;
- (b) the modacrylic fibers and high energy absorptive fibers combined in a uniform distribution to form a yarn end;
- and
- (c) wherein when said yarn is formed into a fabric comprised substantially of said yarn, said fabric meets the American Society for Testing and Materials standard ASTM F 1506 for flame resistance and the National Fire Protection Association standard NFPA 70E for arc thermal performance exposure.

A fabric for use in safety apparel:
- (a) the fabric being formed substantially of flame-resistant yarns formed from an intimate mixture of modacrylic fibers and high energy absorptive fibers, the modacrylic fibers comprising at least about 70 percent of the fibers;
- and
- (b) wherein, when a cationic dye is applied to said fabric, the dyed fabric meets the American National Standard Institute standard ANSI/ISEA-107 minimum conspicuity level class requirements for occupational activities for high-visibility safety apparel, the American society for Testing and Materials standard ASTM F-1506 for flame resistance and the National Fire Protection Association standard NFPA 70E for arch thermal performance exposure.
A safety garment having high visibility and flame resistant characteristics formed from:
- (a) the fabric being formed substantially of flame-resistant yarns formed from an intimate mixture of modacrylic fibers and high energy absorptive fibers, the modacrylic fibers comprising at least about 70 percent of the fibers;
- (b) a cationic dye applied to said fabric;
- and
- (c) wherein said dyed fabric meets the American National Standard Institute standard ANSI/ISEA-107 minimum conspicuity level class requirements for occupational activities for high-visibility safety apparel, the American society for Testing and Materials standard ASTM F-1506 for flame resistance and the National Fire Protection Association standard NFPA 70E for arch thermal performance exposure.
