Velour fabric articles having flame retardance and improved dynamic insulation performance
First Claim
1. A method of forming a velour fabric body, said method comprising the steps of:
- joining a loop yarn and a filament stitch yarn to form a fabric prebody, the filament stitch yarn forming a technical face of the fabric prebody and the loop yarn forming a technical back of the fabric prebody, the filament stitch yarn comprising heat sensitive material and the loop yarn comprising flame retardant material,finishing at least one of said technical face and said technical back of the fabric prebody, thereby to form a velour fabric body having at least one velour surface region, and entangling raised fibers of at least one of the technical face and the technical back, including in and/or through interstices of the fabric body, thereby to increase density and tortuosity of the fiber body, the fabric body having permeability of about 90 ft3/ft2/min or less under a pressure difference of ½
inch of water across the fabric body.

Abstract
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.
