Abstract

The woven fabric according to the invention comprises a warp and weft yarns, the weft yarns comprise first weft yarns and second weft yarns, the first weft yarns and the warp yarns form a base layer of the fabric, while the at least one plurality of second weft yarns forms an additional layer of the fabric that can be broken under a stress without damaging the base layer to change the appearance of the fabric and of the clothing articles made of said fabric.

First claim

The invention claimed is:

1. A clothing article ( 10 ) comprising a woven fabric ( 1 ) comprising warp yarns ( 2 ) and weft yarns ( 3 , 4 ) woven together, said fabric having a front side ( 5 ) and a back side ( 6 ) wherein said front side ( 5 ) of the fabric ( 1 ) is the external side of the clothing article when the article is worn, and said back side ( 6 ) is the internal not visible side when the article is worn, wherein: said weft yarns comprise a plurality of first weft yarns ( 3 ) and at least one plurality of second weft yarns ( 4 ); said plurality of warp yarns ( 2 ) and said plurality of first weft yarns ( 3 ) form a base layer (la) of said fabric; and said at least one plurality of second weft yarns ( 4 ) form an additional layer ( 1 b ) of said fabric in the form of over portions ( 7 ′), characterized in that said an additional layer ( 1 b ) is located on the front side ( 5 ) of the fabric and in that said first ( 3 ) and second ( 4 ) weft yarns are different and are selected to give a different behaviour with respect to a same stress applied to an area of said fabric, so that at least part of said second weft yarns ( 4 ) in said additional layer ( 1 b ) of the fabric breaks under said stress applied to at least one area ( 11 ) of said fabric and at least said first weft yarns ( 3 ) of said base layer ( 1 a ) within said areas ( 11 ) withstand the said stress, and
wherein at least a portion of the second weft yarns are broken and at least part of at least some of the broken second weft yarns is removed from the fabric.

2. The clothing article according to claim 1 , wherein said stress is a mechanical stress.

3. The clothing article according to claim 2 , wherein the breaking force of said second weft yarns ( 4 ) is 3 to 5 times less than the breaking force of said first weft yarns ( 3 ).

4. The clothing article according to claim 1 , wherein a yarn count of said second weft yarns ( 4 ) is 5 to 8 times less than a yarn count of said first weft yarns ( 3 ).

5. The clothing article according to claim 1 , wherein said second weft yarns ( 4 ) extend to form over portions ( 7 ) along the front side ( 5 ) of the fabric by passing over three or more warp yarns ( 2 ).

6. The clothing article according to claim 5 , wherein said second weft yarns ( 4 ) extend to form over portions ( 7 ) along the front side ( 5 ) of the fabric by passing over up to twenty warp yarns ( 2 ).

7. The clothing article according to claim 1 , wherein said first weft yarns ( 3 ) extend to form under portions ( 8 ) along the back side ( 6 ) of the fabric by passing below two or more warp yarns ( 2 ).

8. The clothing article according to claim 1 , wherein said second weft yarns ( 4 ) are made by single yarns and wherein said warp yarns ( 2 ) and/or said first weft yarns are made by single and/or twisted yarns.

9. The clothing article according to claim 1 , wherein said second weft yarns ( 4 ) have different color with respect to said first weft yarns ( 3 ) and/or said warp yarns ( 2 ).

10. The clothing article according to claim 1 , wherein said second weft yarns ( 4 ) are made by a different material with respect to said first weft yarns ( 3 ) and/or said warp yarns ( 2 ).

11. The clothing article according to claim 1 , wherein the fabric is a denim fabric.

12. The clothing article according to claim 1 , wherein said warp yarns ( 2 ) and said first weft yarns ( 3 ) are woven to form a warp faced twill fabric.

13. A woven fabric ( 1 ) comprising warp yarns ( 2 ) and weft yarns ( 3 , 4 ) woven together, said fabric having a front side ( 5 ) and a back side ( 6 ), wherein: said weft yarns comprise a plurality of first weft yarns ( 3 ) and at least one plurality of second weft yarns ( 4 ); said plurality of warp yarns ( 2 ) and said plurality of first weft yarns ( 3 ) form a base layer ( 1 a ) of said fabric; and said at least one plurality of second weft yarns ( 4 ) form an additional layer ( 1 b ) of said fabric in the form of over portions ( 7 ), characterized in that said an additional layer ( 1 b ) is located on the front side ( 5 ) of the fabric and in that said first ( 3 ) and second ( 4 ) weft yarns are different and are selected give a different behaviour with respect to a same stress applied to an area of said fabric, so that at least part of said second weft yarns ( 4 ) in said additional layer ( 1 b ) of the fabric breaks under said stress applied to at least one area ( 11 ) of said fabric and at least said first weft yarns ( 3 ) of said base layer ( 1 a ) within said areas ( 11 ) withstand the said stress, wherein the breaking force of said second weft yarns ( 4 ) is lower than the breaking force of said first weft yarns ( 3 ) and wherein said second weft yarns ( 4 ) extend to form over portions ( 7 ) along the front side ( 5 ) of the fabric by passing over three or more warp yarns ( 2 ), and
wherein at least a portion of the second weft yarns are broken and at least part of at least some of the broken second weft yarns are removed from the fabric.

14. The clothing article according to claim 1 , wherein said second weft yarns ( 4 ) extend to form over portions ( 7 ) along the front side ( 5 ) of the fabric by passing over five or more warp yarns ( 2 ).

15. The clothing article according to claim 1 , wherein said second weft yarns ( 4 ) extend to form over portions ( 7 ) along the front side ( 5 ) of the fabric by passing over seven or more warp yarns ( 2 ).

16. The clothing article according to claim 5 , wherein said second weft yarns ( 4 ) extend to form over portions ( 7 ) along the front side ( 5 ) of the fabric by passing over up to fifteen warp yarns ( 2 ).

17. The clothing article according to claim 5 , wherein said second weft yarns ( 4 ) extend to form over portions ( 7 ) along the front side ( 5 ) of the fabric by passing over a maximum of 12 warp yarns.

18. The clothing article according to claim 1 , wherein the fabric is an indigo dyed denim fabric.

19. The clothing article according to claim 1 , wherein a ratio of a breaking force of the first weft yarns to a breaking force of the second weft yarns is in a range of 2:1 to 7:1.
