Abstract

A garment portion made primarily from a material with low-stretch characteristics, having defined stretch zones with greater flexibility is provided herein. The stretch zones have slits through the garment portion. An interior layer having higher stretch characteristics than the garment body portion is affixed to the internal surface of the garment body portion in the area of the stretch zone. The result is a garment portion that is primarily constructed with a low-stretch material that has stretch zones allowing greater flexibility.

First claim

The invention claimed is:

1. A garment portion having stretch zones, the garment portion comprising:
a garment body portion comprising a material having a first set of stretch characteristics, the material having an external surface and an internal surface; and
at least one defined stretch zone on the garment body portion, the at least one defined stretch zone having an area that is less than an area of the garment body portion, the area of the at least one defined stretch zone having outer edges and a middle, the at least one defined stretch zone comprising:
an exterior facing layer defined by the external surface of the garment body portion;
an interior layer affixed to the internal surface of the garment body portion, the interior layer having an area co-extensive with the at least one defined stretch zone and corresponding only to the area of the at least one defined stretch zone, the interior layer having higher stretch properties than the first set of stretch characteristics of the material of the garment body portion; and
a plurality of spaced apart slits extending through the at least one defined stretch zone of the garment body portion, wherein the slits have a longer length in the middle of the area of the stretch zone and taper to a shorter length near the outer edges of the area of the stretch zone.

2. The garment portion of claim 1 , wherein the slits are of varying length across the area of the stretch zone.

3. The garment portion of claim 1 , wherein the interior layer is affixed to the internal surface of the garment body portion with a heat-activated adhesive applied to at least one of the internal surface of the garment body portion in the stretch zone area or to the interior layer.

4. The garment portion of claim 1 , wherein the interior layer is one of a stretch-woven or stretch-knit material.

5. The garment portion of claim 1 , wherein the stretch zone is located in an area of the garment portion subjected to tensioning forces when the garment portion is worn and used, and wherein the slits are oriented orthogonally relative to the tensioning forces.

6. The garment portion of claim 1 , wherein the spacing between the slits of the plurality of slits varies within the stretch zone.

7. The garment portion of claim 1 , wherein the interior layer is a contrasting color to that of the material of the garment body portion.

8. An upper body garment comprising:
a right sleeve having an external surface, an internal surface, and a right elbow region; and
a left sleeve having an external surface, an internal surface, and a left elbow region, the right sleeve and the left sleeve comprising a material having a first set of stretch characteristics;
wherein the right elbow region includes a right stretch zone and the left elbow region includes a left stretch zone, the stretch zones having an area defining outer edges and a middle, each stretch zone comprising:
an exterior facing layer defined by the external surface of the corresponding right sleeve and left sleeve;
an interior layer affixed to the internal surface of the corresponding right sleeve and left sleeve, the interior layer having an area corresponding to the area of the respective stretch zone the interior layer having higher stretch properties than the first set of stretch characteristics; and
a plurality of spaced apart elbow slits extending through the stretch zone,
wherein a length of the plurality of spaced apart elbow slits varies across the stretch zone such that the length of the plurality of spaced apart elbow slits is longer in the middle of the stretch zone than near the outer edges of the stretch zone.

9. The upper body garment of claim 8 , wherein the interior layer of the stretch zone is affixed to an interior surface of the corresponding right sleeve and left sleeve with a heat activated adhesive applied to at least one of the internal surface of the corresponding right sleeve and left sleeve in the stretch zone area or to the interior layer.

10. The upper body garment of claim 9 , wherein the interior layer is one of a stretch-woven or a stretch-knit material.

11. The upper body garment of claim 7 , wherein the spacing between the slits of the plurality of elbow slits varies within the stretch zone.

12. The upper body garment of claim 11 , wherein the interior layer is a contrasting color to that of the exterior layer.

13. A method of manufacturing a garment portion having stretch zones, the method comprising:
defining at least one stretch zone area on a garment body portion comprising a material having a first set of stretch characteristics, an external surface and an internal surface, the at least one stretch zone area defining outer edges and a middle and having an area that is less than an area of the garment body portion;
creating a plurality of spaced apart slits that are of varying length and that are longer in the middle of the at least one stretch zone and taper to be shorter near the outer edges of the at least one stretch zone, the slits extending through the material of the garment body portion within the at least one stretch zone area; and
affixing an interior layer having an area co-extensive with the stretch zone and corresponding only to the at least one stretch zone area to an internal surface of the garment body portion in the at least one stretch zone area.

14. The method of manufacturing of claim 13 , further comprising coupling a heat-activated adhesive layer on an internal surface of the garment body portion in the at least one stretch zone area, wherein the affixing comprises activating the heat-activated adhesive.

15. The method of manufacturing of claim 14 , wherein the step of creating a plurality of spaced apart slits further comprises creating a plurality of spaced apart slits having varying widths.

16. The method of manufacturing of claim 15 , wherein the step of creating a plurality of spaced apart slits further comprises creating the plurality of spaced apart slits in an orthogonal orientation relative to an area of tensioning force when the garment portion is in an as-worn configuration.
