## 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.

## Claims

### Claim 1

A flame resistant panel, comprising:
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; and
a layer comprising a plurality of substantially vertically oriented flame retardant treated fibers extending from the top surface to the bottom surface.

### Claim 2 (depends on 1)

The flame resistant panel of claim 1, wherein the substantially vertically oriented flame retardant treated fibers are fire retardant treated lyocell fibers.

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 1)

The fire resistant batting material of claim 1, wherein the fibers of the substantially vertically oriented flame retardant treated fibers are selected from the group consisting of polyester, polyolefins, cellulosic fibers and mixtures thereof.

### Claim 5 (depends on 4)

The fire retardant batting material of claim 4, wherein the cellulosic fibers comprise as cotton, rayon, wool, silk, acetate, nylon, lyocell, flax, ramie, jute, angora, kenaf or mixtures thereof.

### Claim 6 (depends on 1)

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

### Claim 7 (depends on 1)

The flame resistant panel of claim 1, wherein a loading of the fire retardant material of the substantially vertically oriented flame retardant fibers treated is in an amount effective to meet a flammability standard defined in 16 CFR Part 1633 (2007).

### Claim 8 (depends on 1)

The flame resistant panel of claim 1, wherein the fire retardant material of the substantially vertically oriented flame retardant treated fibers comprises halogenated compounds, phosphorous containing compounds, sulfate containing compounds, metal hydroxides, borates, silicon based compounds, melamine based compounds, phosphonic acid derivatives, intumescent compounds, and mixtures thereof.

### Claim 9 (depends on 1)

The flame resistant panel of claim 1, wherein the batting material has a thickness greater than 0.5 inches to 3 inches.

### Claim 10 (depends on 1)

The flame resistant panel of claim 1, wherein the substantially vertically oriented flame retardant treated fibers comprise lyocell fibers treated with ammonium polyphosphate.

### Claim 11 (depends on 1)

The flame resistant panel of claim 1, wherein the substantially vertically oriented flame retardant treated fibers are greater than 50 percent of the layer.

### Claim 12 (depends on 1)

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

### Claim 13 (depends on 1)

The flame resistant panel of claim 1, wherein the substantially vertically oriented flame retardant treated fibers comprise natural fibers.

### Claim 14 (depends on 1)

The flame resistant panel of claim 1, wherein the first and second functional components are adjacent to one another on the fabric and wherein a mixing gap is produced by removal of water, which leads to formation of water-transporting polymer bridges.

### Claim 15 (depends on 1)

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

### Claim 16 (depends on 1)

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.
