## Title
Multi-layered bedclothes material

## Abstract

A material for bedclothes includes first and second outer layers connected together at their peripheries, the first outer layer being made of at least two sub-layers connected together, one sub-layer being a smooth fabric material and a second sub-layer being made of a comfort-adjusting material such as a heat insulating material (fibrous batting). The second outer layer is made of a smooth fabric material (cotton sheeting). The first and second sub-layers can be sewn together to provide a quilted, non-smooth outer surface. The smooth outer layer is intended for contact with a person using the bedclothes.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to bedclothes such as bed sheets, blankets and comforters, and in particular to materials which can be used to make such bedclothes.
2. The Prior Art
Materials used to fabricate bedclothes such as bed sheets, blankets and comforters are well known and include cotton fabrics, satin, linen, polymer and polymer blend fabrics, wool fabrics, down-filled composite materials, etc. However, none of the known materials include a comfort-adjusting material, such as an insulation material, which also provides a smooth surface facing the person using the product.
I have developed such a material.
SUMMARY OF THE INVENTION
According to my invention, a multi-layered bedclothes material includes a first outer layer which includes a comfort-adjusting material and a second outer layer which is made of a smooth fabric, these two outer layers being attached at their peripheries so as to form a bedclothes item such as a flat bedsheet, a fitted bedsheet, a blanket, a comforter, etc. A comfort-adjusting material is a heat-insulating material, a moisture wicking material, or a heat reflecting material. The first outer layer is itself preferably formed of a first (outer) sub-layer that is made of a smooth fabric material and a second (inner) sub-layer that is made of a batting (heat insulating) material, the first and second sub-layers being connected together (e.g. stitched) to provide an outer surface for the bedclothes material which is not smooth (e.g. quilted). The first outer layer can also include a third inner sub-layer of a smooth fabric, with the second batting sub-layer being connected (e.g. stitched) between the first and third smooth fabric sub-layers. The inventive bedclothes material can be used to form flat or fitted bed sheets, blankets, comforters, etc.
The invention will now be better understood by reference to the attached drawings, taken in conjunction with the following discussion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The multi-layered bedclothes material of the present invention can be fabricated into a fitted bed sheet 10 that is mounted on a mattress M in a conventional manner as shown in FIGS. 1 and 2, or it can be fabricated into a flat bed sheet 11 as shown in FIG. 3. The multi-layered  bedclothes material can also be fabricated into other products used with bedding, such as comforters or blankets.
The multi-layered bedclothes material of the invention includes a first comfort-adjusting outer layer and a second smooth outer layer attached (stitched together) at their peripheries. One preferred embodiment is represented in FIGS. 4, 5 and 6. This embodiment includes a first outer layer 20 and a second outer layer 25. The first outer layer 20 is formed of a first outer sub-layer 21 and a second inner sub-layer 22 sewn together in a crisscross fashion 23 to form a quilted (non-smooth) outer surface 21a (see FIG. 5). The first outer sub-layer 21 is made of a smooth cotton or a polycotton cloth fabric and the second inner sub-layer 22 is made of a polyester or polyester/acrylic blend fiberfill fabric. The second outer layer 25 is formed of cotton sheeting. The second outer layer 25 is intended for contact with the person laying in a bed whereas the first outer layer in this embodiment provides insulation and warmth.
Another preferred embodiment of the inventive multi-layered bedclothes material is represented in FIGS. 7 and 8. This embodiment includes a first outer layer 30 and a second outer layer 35. The first outer layer 30 is formed of a first outer sub-layer 31, a second inner sub-layer 32 and a third inner sub-layer 33, these sub-layers being sewn together with crisscross stitching 34 to form a quilted outer surface 31a (see FIG. 8). The first outer sub-layer 31 is made of a smooth cotton or a polycotton cloth fabric, the second sub-layer 32 is made of a polyester or polyester/acrylic blend fiberfill fabric, and the third sublayer 33 is made of a poly or polycotton sheeting fabric. The second outer layer 35 is formed of cotton sheeting and is intended for direct contact by the person lying in a bed. The first outer layer 30 in this embodiment provides insulation and warmth. The additional sub-layer 33 in this embodiment prevents bunching of the sub-layer 32 during the sewing process.
It should be understood that the first outer layer of the multi-layered bedclothes material of the invention need not be constructed as shown in FIGS. 4–8 but can include a down-filled layered fabric material. The second sub-layer of the first outer layer can be made of a material which wicks moisture away from a person in the bed, or a heat-reflecting (cooling) material.
