Abstract
A fabric for use in arc and flame protection, is made up of: more than 15% weight percent (wt %) aramids; less than 50% wt % modacrylic; less than 50% wt % cellulose; and less than 15% wt % nylon. A process for producing the fire-resistant fabric involves shredding recycled fire-resistant garments into fibers; creating yarn from the shredded fibers; weaving the yarn into fabric; and knitting the yarn to produce new garments. The fabric may be used to produce fire-resistant garments worn by workers in many industries such as the oil and gas.
