Abstract

Temperature management bedding systems for mattresses and quilt panels generally include a trilayer of active components including a phase change material applied to a top surface of a flexible substrate thereof, a fire retardant layer underlying the flexible substrate including hydrophilic rayon fibers treated with ammonium polyphosphate; and a vertically oriented fiber batting layer underlying the first retardant layer including an elastomeric binder. The temperature management bedding systems provide heat control and mass transfer of moisture from the bedding surface.

First claim

What is claimed is:

1. A quilt panel comprising
a top fabric layer;
a trilayer of active components comprising
a phase change material applied to a top surface of a flexible substrate thereof,
a fire retardant layer underlying the flexible substrate including hydrophilic rayon fibers treated with ammonium polyphosphate; and
a vertically oriented fiber batting layer underlying the first retardant layer including an elastomeric binder; and

a bottom layer, wherein the top fabric layer and the bottom layer are joined at least about a perimeter thereof and encapsulate the trilayer of active components.

2. The quilt panel of claim 1 , further comprising one or more layers intermediate the top fabric layer and the bottom layer.

3. The quilt panel of claim 1 , wherein the phase change material is in the form of a coating on the flexible substrate.

4. The quilt panel of claim 3 , wherein the flexible substrate comprises a fabric layer, foam layer, a fiber layer or a combination thereof.

5. The quilt panel of claim 3 , wherein the flexible substrate is a non-woven substrate.

6. The quilt panel of claim 1 , wherein the fire retardant layer comprises lyocell fibers.

7. The quilt panel of claim 1 , wherein the fire retardant layer further comprises silver ions dispersed throughout.

8. The quilt panel of claim 7 , wherein the silver ions comprise a polymer emulsion comprising, based on a dry weight of the emulsion, from 90 to 99.9 wt % of a polymer A comprising acrylic, styrene-acrylic, or vinyl acetate-acrylic emulsion polymers, from 0.025 to 2 wt % of an oxidant selected from peroxides, halic acids, hypohalous acids, halous acids, perhalic acids, their salts, and combinations thereof, and from 0.002 to 0.5 wt % of silver, wherein the silver ions are complexed with a copolymer B that comprises from 5 to 95 wt % a heterocyclic containing monomer residue.

9. The quilt panel of claim 1 , wherein the ammonium polyphosphate is a loading of 13 to 20% based on a total weight of the fiber and the fire retardant.

10. The quilt panel of claim 1 , wherein the vertically oriented fibers are in the form of pleats.

11. The quilt panel of claim 1 , wherein the layer of vertically oriented fibers have a thickness greater than 0.5 inches to 3 inches.

12. The quilt panel of claim 1 , wherein the fire retardant layer including the hydrophilic rayon fibers are carded and crosslapped.

13. The quilt panel of claim 1 , wherein the fire retardant layer including the hydrophilic rayon fibers are vertically oriented.

14. The quilt panel of claim 1 , wherein the silver ions comprises a polymer emulsion comprising, based on a dry weight of the emulsion, from 90 to 99.9 wt % of a polymer A comprising acrylic, styrene-acrylic, or vinyl acetate-acrylic emulsion polymers, from 0.025 to 2 wt % of an oxidant selected from peroxides, halic acids, hypohalous acids, halous acids, perhalic acids, their salts, and combinations thereof, and from 0.002 to 0.5 wt % of silver, wherein the silver is complexed with a copolymer B that comprises from 5 to 95 wt % a heterocyclic containing monomer residue.

15. The quilt panel of claim 1 , wherein the quilt panel overlies a mattress structure, a seating structure, or is a cushion layer in a shoe structure.

16. A mattress comprising:
a mattress core; and
a quilt panel coupled to the mattress core, the quilt panel comprising a top fabric layer; a trilayer of active components comprising a phase change material applied to a top surface of a flexible substrate thereof, a fire retardant layer underlying the flexible substrate including hydrophilic rayon fibers treated with ammonium polyphosphate; and a vertically oriented fiber batting layer underlying the first retardant layer including an elastomeric binder; and a bottom layer, wherein the top fabric layer and the bottom layer are joined at least about a perimeter thereof and encapsulate the trilayer of active components.

17. The mattress of claim 16 , further comprising one or more layers intermediate the top fabric layer and the bottom layer.

18. The mattress of claim 16 , wherein the phase change material is in the form of a coating on the flexible substrate.

19. The mattress of claim 18 , wherein the flexible substrate comprises a fabric layer, foam layer, a fiber layer or a combination thereof.

20. The mattress of claim 18 , wherein the flexible substrate is a non-woven substrate.

21. The mattress of claim 16 , wherein the fire retardant layer comprises lyocell fibers.

22. The mattress of claim 16 , wherein the fire retardant layer further comprises silver ions dispersed throughout.

23. The mattress of claim 22 , wherein the silver ions comprise a polymer emulsion comprising, based on a dry weight of the emulsion, from 90 to 99.9 wt % of a polymer A comprising acrylic, styrene-acrylic, or vinyl acetate-acrylic emulsion polymers, from 0.025 to 2 wt % of an oxidant selected from peroxides, halic acids, hypohalous acids, halous acids, perhalic acids, their salts, and combinations thereof, and from 0.002 to 0.5 wt % of silver, wherein the silver ions are complexed with a copolymer B that comprises from 5 to 95 wt % a heterocyclic containing monomer residue.

24. The mattress of claim 16 , wherein the ammonium polyphosphate is a loading of 13 to 20% based on a total weight of the fiber and the fire retardant.

25. The mattress of claim 16 , wherein the vertically oriented fibers are in the form of pleats.

26. The mattress of claim 16 , wherein the layer of vertically oriented fibers have a thickness greater than 0.5 inches to 3 inches.

27. The mattress of claim 16 , wherein the fire retardant layer including the hydrophilic rayon fibers are carded and crosslapped.

28. The mattress of claim 16 , wherein the fire retardant layer including the hydrophilic rayon fibers are vertically oriented.

29. The mattress of claim 16 , wherein the silver ions comprises a polymer emulsion comprising, based on a dry weight of the emulsion, from 90 to 99.9 wt % of a polymer A comprising acrylic, styrene-acrylic, or vinyl acetate-acrylic emulsion polymers, from 0.025 to 2 wt % of an oxidant selected from peroxides, halic acids, hypohalous acids, halous acids, perhalic acids, their salts, and combinations thereof, and from 0.002 to 0.5 wt % of silver, wherein the silver is complexed with a copolymer B that comprises from 5 to 95 wt % a heterocyclic containing monomer residue.
