Blend of lyocell and flame resistant fibers for protective garments
A unique blend of fibers used to create a yarn or fabric useful in protective garments including a lyocell fiber, and a flame resistant fiber that is not a modacrylic and/or does not require the emission of gases and/or acids for flame resistance. The lyocell fiber is approximately 5% to 55% of the blend, and the flame resistant fiber is approximately 45% to 95% of the blend. The resulting fabric requires no post treatment for flame resistance.
1. A textile fabric for a protective garment consisting of:
5-20% by weight of a non-FR lyocell fiber,
10-30% by weight of an inherently FR fiber, the inherently FR fiber is not a modacrylic fiber, and
50-85% by weight of an FR cellulosic fiber, and
the fabric reports no break open per ASTM F1930 at four seconds.
2. The textile fabric of claim 1 wherein the inherently FR fiber is made from a polymer selected from the group consisting of aramid, polyamide-imide, melamine, PBI, polyimide, PBO, PPS, PEEK.
3. The textile fabric of claim 2 wherein the inherently FR fiber is made from a polymer selected from the group consisting of PBI and PBO.
4. The textile fabric of claim 2 wherein the inherently FR fiber is made of PBI.
5. The textile fabric of claim 1 wherein the FR cellulosic fiber is an FR rayon.
6. The textile fabric of claim 1 wherein the fabric includes
10% by weight of a non-FR lyocell fiber,
20% by weight of an inherently FR fiber, and
70% by weight of an FR cellulosic fiber.
