Abstract

Mattress assemblies including fiber panels generally include bicomponent fibers including optically active particles within a core thereof. The bicomponent fibers can be treated with a fire retardant or untreated and blended with fire retardant fibers. The bicomponent fibers are configured to transform radiant body heat of an end user.

First claim

What is claimed is:

1. A mattress assembly comprising:
a fiber batting layer having a top planar surface and a bottom planar surface overlying a mattress core, the fiber batting layer comprises a plurality of fibers comprising a blend of fire retardant treated bicomponent fibers and untreated lyocell fibers, wherein the fire retardant treated bicomponent fibers consist of a polyethylene terephthalate core and a sheath about the core, and optically active particles embedded in the core, and a fire retardant material, wherein the optically active particles comprise one or more of aluminum oxide (Al 2 O 3 ), quartz (SIO 2 ), and titanium dioxide (TiO 2 ) in rutile form,
wherein the fire retardant treated bicomponent fibers and the lyocell fibers are vertically oriented relative to the underlying mattress core and have fiber lengths within a range of 0.25 and 4 inches, and
wherein the fiber batting layer includes the fire retardant treated bicomponent fibers in an amount effective to meet a flammability standard set forth in 16 C.F.R. Part 1633.

2. The mattress assembly of claim 1 , wherein the fire retardant material is selected from the group consisting of 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.

3. The mattress assembly of claim 1 , wherein the batting material has a thickness greater than 0.5 inches to 3 inches.
