Abstract

A double layer sweater which is knit simultaneously of two independent layers, one being an inner layer, and the other layer being an outer layer. Joining the two layers together is a polygonal-shaped quilting stitch pattern forming insulating pockets between the layers. Each layer is different and may be comprised of a blend of wool and acrylic yarn in the outer layer and a synthetic wicking enhanced yarn, such as polyester or acrylic, in the inner layer, such that there is a hydrophilic inner layer and a hydrophobic outer layer. The inner layer is comprised of synthetic yarn with enhanced wicking features. The outer layer of yarn is treated in a bath of teflon material such that the teflon-coated yarn produces the hydrophobic outer layer. The sweater has the properties of insulation to provide warmth to the wearer; has a water repellant and stain resistant outer layer. A wickability inner layer has a capillary action to remove moisture on the skin moving through the inner layer to the outer layer and then evaporated away so that the wearer of the sweater feels dry as well as warm.

Claims

1. A multi-layer garment to be worn by a person comprising

a first layer being an inner layer to be worn adjacent to skin of a person and comprised of a two-yarn knit having two strands of yarn interknit with each other in an interlocking pattern, wherein said inner layer has wickability;

a second layer being an outer layer to be worn away from said person and adjacent to said first layer and comprised of a two-yarn knit having two strands of yarn interknit with each other in an interlocking pattern, wherein said outer layer is made from a wool/acrylic blend yarn for warmth and breathability and said yarn treated with high performance water and stain repellant material to provide a water and stain resistant outer layer;

a series of knit stitches in a shaped pattern for joining said first layer with said second layer, said first layer and said second layer being independent layers; and

a series of insulating pockets formed in said multi-layer garment wherein said stitches joins said first layer with said second layer creates said pockets in said shaped pattern such that said pockets trap body heat in the garment to provide a greater warmth for said person.

2. The multi-layer garment of claim 1, wherein said inner layer is made from yarn to quickly wick away perspiration from the skin allowing it to evaporate through the cloth keeping the person wearing the garment dry and comfortable.

3. The multi-layer garment of claim 1, wherein said shaped pattern is that of a polygon.

4. The multi-layer garment of claim 1,

wherein said inter-locking pattern is formed by a series of inter-locking loops.

9. The multi-layer garment of claim 1, which is a sweater.

5. A multi-layer garment to be worn by a person comprising

a first layer being an inner layer to be worn adjacent to skin of a person and comprised of a two-yarn knit, wherein said inner layer has wickability;

a second layer being an outer layer to be worn away from said person and adjacent to said first layer and comprised of a two-yarn knit, wherein said outer layer is made from a wool/acrylic blend yarn for warmth and breathability and said yarn treated with high performance water and stain repellant material to provide a water and stain resistant outer layer;

a series of knit stitches in a shaped pattern for joining said first layer with said second layer; and

a series of insulating pockets formed in said multi-layer garment wherein said stitches joins said first layer with said second layer creates said pockets in said shaped pattern such that said pockets trap body heat in the garment to provide a greater warmth for said person.

6. The multi-layer garment of claim 5,

wherein said inner layer is made from yarn to quickly wick away perspiration from the skin allowing it to evaporate through the cloth keeping the person wearing the garment dry and comfortable.

7. The multi-layer garment of claim 5,

wherein said shaped pattern is that of a polygon.

8. The multi-layer garment of claim 5, wherein said inter-locking pattern is formed by a series of inter-locking loops.

10. The multi-layer garment of claim 5, which is a sweater.
