Vulcan Twill is our 7.5 oz per sq. yard 100% Cotton Flame Resistant Denim for Shirting. Made from Ring Spun Warp yarn, Vulcan Twill is a great 2x1 Right Hand Twill fabric that gives the look and feel of a Chambray, but has the rugged life wear of a much heavier fabric. Vulcan meets requirements of NFPA 2112 and NFPA 70E as an HRC2 fabric. Under the Vulcan name we feature two indigo dyed fabrics: WSFR is from our “True Blue” shade collection and 9539 is from our “Light Blue” shade.
