Abstract

A fabric having a first side and a second side and comprising weft yarns and warp yarns woven together in pattern. At least some of the weft, or warp, yarns float over a number of warp yarns, or weft yarns, and below a number of warp yarns, or weft yarns, to provide weft, or warp, over portions on the first side and under portions on the second side. The under portions and/or over portions of the yarns form loops. At least some of the yarns that form the loops are conjugate yarns comprising a plurality of filaments that are separable, i.e., splittable into sub-filaments. The loops of the conjugate yarns extend for a length of at least three adjacent warp, or weft, yarns.

Claims

1. A fabric having a first side and a second side, the fabric comprising weft yarns and warp yarns woven together in pattern, wherein at least some of the weft, or warp, yarns float over a plurality of warp yarns, or weft yarns, and below a plurality of warp yarns, or weft yarns, to provide weft, or warp, over portions on said first side and weft, or warp under portions on said second side,

whereby at least one of said under portions and said over portions of the yarns form loops, wherein at least some of said yarns that form said loops are conjugate yarns comprising a plurality of filaments splittable into sub-filaments, and said loops of said conjugate yarns extend for a length of at least three adjacent warp, or weft, yarns,

wherein said under portions form said loops and said over portions define connection portions and said loops extend past a first number of yarns and the connection portions extend past a second number of yarns, the first number being at least 3 times the second number and less than 24 times the second number.

2. The fabric according to claim 1, wherein at least part of said sub-filaments of the loops are separate from each other and at least some of said sub-filaments are broken to provide a plurality of loose ends protruding from a body of the fabric and forming a fleece layer.

3. The fabric according to claim 1, wherein said conjugate yarn has a count comprising between about 75 and 600 den.

4. The fabric according to claim 1, wherein said sub-filaments include a count between 0.01 and 0.5 den.

5. The fabric according to claim 1, wherein said splittable filaments comprise between 3 and 100 said sub-filaments.

6. The fabric according to claim 1, wherein some of said weft yarns are elastic.

7. The fabric according to claim 1, wherein said conjugate yarns extend in a first direction and a ratio of said conjugate yarn to other ones of said weft or warp yarns extending in said first direction, lies between 5:

1 and 1;

2.

8. The fabric according to claim 1, wherein at least one of a warp density and a weft density is between approximately 25 and 80 warps/cm after three home washes.

9. The fabric according to claim 1, herein said fabric is a denim fabric.

10. The fabric according to claim 9, wherein said denim fabric includes said first side having a denim appearance and said second side being a fleece layer.

11. The fabric according to claim 1, wherein said warp yarns have an English cotton number between approximately Ne 4 and Ne100.

12. The fabric according to claim 1, wherein said loops are on said first side of said fabric and on said second side of said fabric, said conjugate yarns pass over a weft yarn or a warp yarn, and further yarns adjacent to said conjugate yarns pass over the same weft or warp yarn passed over by the conjugate yarn, or a weft or warp yarn that is adjacent to the weft or warp yarn passed over by the conjugate yarn.

13. The fabric according to claim, 1, wherein a length of the loops of said conjugate yarns is at least 1.5 times greater than a length of said under or over portions of other ones of said yarns.

14. The fabric according to claim 1, wherein said conjugate yarn has a count comprising between about 20 and 1800 den.

15. A method for producing a fabric, the method comprising:

providing warp yarns;

providing weft yarns, wherein at least one of;

at least some of said warp yarns are conjugate yarns; and

, at least some of said weft yarns are said conjugate yarns,

said conjugate yarns comprising a plurality of filaments splittable into a bundle of sub-filaments and said conjugate yarns including under portions and over portions with respect to said warp or weft yarns; and

forming loops with one of said under portions and said over portions of said conjugate yarns, and forming connection portions with the other of said under portion and said over portions of said conjugate yarns, said loops extend past a first number of weft or warp yarns and the connection portions extend past a second number of weft or warp yarns, the first number being at least 3 times the second number and less than 24 times the second number.

16. The method according to claim 15, further comprising:

splitting at least part of said filaments into said sub-filaments; and

breaking apart at least part of said sub-filaments to form fleece.

17. The method according to claim 16, further comprising tailoring said fabric into a garment after said splitting.

18. The method according to claim 17, wherein said conjugate yarns are weft yarns and said weft yarns include further weft yarns.

19. The method according to claim 16, wherein at least one of said splitting and said breaking apart is carried out by a process selected from the group consisting of:

stone washing, perlite washing, sand blasting, hand-scraping, laser treatments, bleaching, caustic-shrinking washing, enzyme biostoning, chemical treatments, thermal treatments, mechanical treatments, and abrasion on fabric.

20. An article comprising a fabric having a first side and a second side, the fabric comprising weft yarns and warp yarns woven together in pattern, wherein at least some of the weft, or warp, yarns float over a plurality of warp yarns, or weft yarns, and below a plurality of warp yarns, or weft yarns, to provide weft, or warp, over portions on said first side and weft, or warp under portions on said second side,

wherein at least one of said under portions and said over of the yarns form loops and at least some of said yarns that form said loops are conjugate yarns comprising a plurality of filaments splittable into sub-filaments, and said loops of said conjugate yarns extend for a length of at least three adjacent warp, or weft yarns,

wherein said under portions form said loops and said over portions define connection portions and said loops extend past a first number of yarns and the connection portions extend past a second number of yarns, the first number being at least 3 times the second number and less than 24 times the second number,

said article comprising a garment.

21. The article according to claim 20, wherein said fabric is a denim fabric that includes said first side having a denim appearance and said second side being a fleece layer and said garment comprise one of pants, jeans, a shirt, a sweater, a jacket and track suit bottoms.
