Stitchbonded inherently flame resistant fabrics
The invention relates to an inherently flame resistant (FR) stitchbonded nonwoven fabric for mattresses, boxsprings, upholstered furniture, top-of-the-bed, office panel, transportation seating or any end use application where a FR textile material is desired. Two of the preferred forms of this invention include: 100% cotton. 100% rayon, 100% lyocell, cotton/non-FR fiber blends, rayon/non-FR fiber blends or lyocell/non-FR fiber blend battings that are stitchbonded with flame resistant fiberglass core-spun yarn. 100% cotton, 100% rayon, 100% lyocell, cotton/non-FR fiber blends, rayon/non-FR fiber blends or lyocell/non-FR fiber blend battings that are stitchbonded with FR spun yarn.
1. A flame resistant, stitchbonded nonwoven fabric comprised of batting that is stitchbonded with a fire resistant spun stitching yarn, which is a blend of char-forming flame resistant staple fibers and oxygen depleting flame resistant staple fibers, or a fiberglass core-spun yarn;
wherein the batting consists of 100% cotton, 100% rayon, 100% lyocell, cotton/non-FR fiber blends, rayon/non-FR fiber blends or lyocell/non-FR fiber blends.
2. The fabric of claim 1 , wherein the yarn comprises a blend of char forming flame resistant staple fibers and oxygen depleting flame resistant staple fibers.
3. The fabric of claim 2 , wherein the yarn further comprises non-flame resistant staple fibers.
4. The fabric of claim 1 , wherein the yarn is comprised of a flame resistant fiberglass core-spun yarn.
5. The fabric of claim 1 , comprised of from 5 to 50 wt % of flame resistant stitching yarn, and 50 to 95 wt % of the batting.
6. The fabric of claim 5 , wherein the amount of flame resistant stitching yarn ranges from 15 to 35 wt %.
7. The fabric of claim 1 , wherein the batting is stitchbonded with a flame resistant fiberglass core-spun yarn.
8. The fabric of claim 5 , wherein the batting comprises nonwoven batting.
