Abstract

Flame retardant panels generally include an adaptive cover layer and underlying batting layer. The cover layer includes a moisture vapor permeable synthetic fibrous layer, and a liquid impermeable but moisture vapor permeable thermoplastic layer disposed on an outer face of the cover layer, wherein the liquid impermeable but moisture vapor permeable thermoplastic layer is in an amount of about 2 to 15% by weight based on a total weight of the synthetic fibrous layer and the thermoplastic layer. The underlying batting layer can have a top surface and a bottom surface, the layer comprising a plurality of substantially vertically oriented flame retardant treated fibers extending from the top surface to the bottom surface; and a binder material.

First claim

What is claimed is:

1. A flame resistant panel, consisting of:
an adaptive cover layer comprising a multifunctional layer disposed on a fabric, wherein the multifunctional layer comprises a first functional component and a second functional component, the second functional component having a chemical-functional and constitutional specification for responsive behavior or a responsive property reversibly switchable by external stimulus, wherein the first and second functional components are different, wherein the first and second functional components are adjacent to one another on the fabric in a planar arrangement, wherein the first functional component is selected to be hydrophobic having a fixed length and the second functional component is selected to be hydrophilic at a first temperature and at a first length, and evaporative at a second temperature by a contraction in the first length, and
a fire retardant layer comprising a plurality of substantially vertically oriented flame retardant treated lyocell fibers having been treated with a fire retardant chemical consisting of ammonium polyphosphate permeating substantially throughout a cross-sectional area of the lyocell fibers such that the plurality of substantially vertically oriented flame retardant treated lyocell fibers consist of lyocell fibers and the ammonium polyphosphate, and a plurality of vertically oriented non-flame retardant treated fibers extending from a top surface to a bottom surface of the fire retardant layer, wherein the fire retardant layer underlies the adaptive cover layer, wherein a loading of the fire retardant chemical in the fire retardant layer comprising the plurality of substantially vertically oriented flame retardant lyocell fibers treated is in an amount effective to meet a flammability standard defined in 16 CFR Part 1633 (2007), and wherein the adaptive cover layer in combination with the fire retardant layer are configured to encapsulate a mattress core.

2. The flame resistant panel of claim 1 , wherein the first functional component is a spacer polymer.

3. The flame resistant panel of claim 1 , wherein the plurality of vertically oriented non-flame retardant treated fibers are selected from the group consisting of polyester, polyolefins, cellulosic fibers and mixtures thereof.

4. The flame resistant panel of claim 3 , wherein the cellulosic fibers comprise as cotton, rayon, wool, silk, acetate, nylon, lyocell, flax, ramie, jute, angora, kenaf or mixtures thereof.

5. The flame resistant panel of claim 1 , wherein the flame resistant panel has a basis weight of 5 to 18 ounces per square yard.

6. The flame resistant panel of claim 1 , wherein the flame resistant panel is a batting material, wherein the batting material has a thickness within a range of 0.5 inches to 3 inches.

7. The flame resistant panel of claim 1 , wherein the substantially vertically oriented flame retardant treated lyocell fibers and the vertically oriented non-flame retardant treated fibers extending from the top surface to the bottom surface are in the form of pleats.

8. The flame resistant panel of claim 1 , wherein the external stimulus is temperature.

9. The flame resistant panel of claim 1 , wherein the second functional component is a responsive polymer selected from a group consisting of polyethylene oxide, polypropylene oxide derivatives, and copolymerizates thereof; ethoxylated and propoxylated polysaccharides; polyacrylamides; polyacrylates; and polyelectrolytes.

10. The flame resistant panel of claim 1 , wherein the flame resistant panel is a batting material encapsulating the mattress core.

11. The flame resistant panel of claim 1 , wherein the flame resistant panel is a component in a mattress assembly.
