Mount Vernon FR is giving the workwear consumer what they want: comfort and movement.

The mill announced Thursday it is expanding its collection of flame resistant (FR) FlexTex fabrics engineered with stretch for increased comfort and mobility. The collection now includes six denim and four piece-dyed FR fabrics.

Mount Vernon tapped stylists from apparel manufacturers to help develop the line, resulting in garments that feature the authentic look of rigid denim but with enhanced stretch and comfort qualities. Mount Vernon FR FlexTex fabrics meet the performance requirements of ASTM F1506 and are NFPA 2112 component recognized.

“We believe workers should have comfortable clothing options on the job and off,” said Mike Woods, vice president of FR fabrics for Mount Vernon FR. “We’ve developed our line of FR FlexTex fabrics with the comfort and character of everyday denim and piece-dyed fabrics, combined with the exceptional protection and durability of Mount Vernon FR fabrics.”

FlexTex fabrics are made using an elastomeric fiber that adds mobility to fabric, so workers experience increased range of motion in their FR apparel. Most FlexTex fabrics can stretch from 12 to 15 percent, but the latest Mount Vernon FR fabric developments incorporate TreFlex yarn, which may allow as much as 20 percent stretch. Treflex provides stretch properties and shrinkage control.

The expanded offering of FlexTex fabric constructions includes twill, canvas and oxford, and a variety of desirable vintage appearances can be achieved through increased yarn character and slub effects.
