Abstract

A fabric is provided for use in safety apparel, including a first yarn type comprising at least about 60 percent modacylic fibers and a second yarn type comprising an intimate blend of anti-static fibers and other fibers selected from the group of fibers consisting of polyester, nylon, rayon, modacrylic, cotton, wool, and combinations thereof. The fabric meets the American Society for Testing and Materials standard ASTM F-1506 for flame resistance, Federal Test Method Standard 191A, Method 5931 for electrostatic decay, and the Electrostatic Discharge Association Advisory ADV11.2-1995 voltage potential.

Dependent claims

A fabric of the type formed of warp and weft yarns for use in safety apparel comprising:

(a) a first body yarn comprising at least 60% modacrylic fibers and no anti-static fibers;
(b) a second anti-static yarn comprising an intimate blend of anti-static fibers and other fibers selected from the group consisting of polyester, nylon, rayon, modacrylic, cotton, wool, and combinations thereof.
(c) the fabric being formed primarily of the first body yarns, and a minor number of the second anti-static yarns occurring at spaced distances in both the warp and the weft directions;
(d) wherein the fabric meets the American Society for Testing and Materials standard ASTM F-1506 for flame resistance, Federal Test Method Standard 191A, Method 5331 for electrostatic decay, and the Electrostatic Discharge Association Advisory ADV11.2-1995 voltage potential;
and
(e) wherein the fabric includes a high visibility dye that meets the American National Standards Institute standard ANSI/ISEA-107 minimum conspicuity requirements for occupational activities for high visibility safety apparel.
