摘要:
A velour fabric article consists of a fabric body having a technical face formed by a filament stitch yarn and a technical back formed by a loop yarn. The filament stitch yarn includes a heat sensitive material, e.g. a hot melt material or a heat shrinkable material, and/or an elastomeric material, such as spandex. The loop yarn includes flame retardant material, such as M-Aramide fiber. The fabric body has a velour surface formed at one or both of the technical back and the technical face. Raised fibers of at least one of the technical face and the technical back may be entangled, including in and/or through interstices of the fabric body, toward the other of the technical face and the technical back, e.g., by a hydroentanglement process applied after finishing. The fabric body has permeability of about 90 ft3/ft2/min, or less, under a pressure difference of ½ inch of water across the fabric body.
