FLAME RETARDANT STRETCH FIBER STRUCTURE, FLAME RETARDANT STRETCH WOVEN/KNITTED FABRIC, FLAME RETARDANT STRETCH CORE SPUN YARN, AND PROTECTIVE CLOTHING USING SAME

摘要

The purpose of the present invention is to impart stretchability to a flame retardant structure composed of pilling-resistant flame retardant modacrylic fiber and blended yarn. This flame retardant stretch fiber structure is characterized in that the flame retardant modacrylic fiber blend ratio is 44-79 weight%, the regenerated cellulose fiber blend ratio is 17-50 weight%, and the polyurethane elastic fiber blend ratio is 2-10 weight%. Afterflame and afterglow according to the ISO 15025 A method both average 2.0 seconds or less.
