Abstract

A fabric with moisture management properties has a pattern of hydrophobic areas comprising at least one hydrophobic agent provided at least on the first side of the fabric and at least one hydrophilic agent which is provided in a pattern on at least some regions of said first side of the fabric, whereby said first side has a pattern of hydrophobic areas and a pattern of hydrophilic areas to transfer the moisture from the first side to the second side.

Claims

1. A fabric (1), having a first side (11), a second side (12), a body (13) extending from said first side (11) to said second side (12);

at least one hydrophobic agent (14), provided at least on said first side (11) of said fabric (1) as a pattern of hydrophobic areas (16),

wherein said fabric (1) comprises;

at least one hydrophilic agent (15) which is provided on at least some regions of said first side (11) of the fabric (1), whereby said first side (11) has a pattern of said hydrophobic areas (16) and a pattern of hydrophilic areas (17), to transfer moisture (30) from said first side (11) to said second side (12).

2. The fabric (1) according to claim 1, wherein said hydrophobic areas (16) comprise a hydrophobic agent (14) and a hydrophilic agent (15).

3. The fabric (1) according to claim 2, wherein said hydrophobic areas (16) comprise a film on the first side (11) of the fabric (1).

4. The fabric (1) according to claim 1, wherein the minimum distance between two said adjacent hydrophobic areas is in the range of 0.3 to 0.4 mm.

5. The fabric (1) according to claim 1, wherein the maximum distance between two said adjacent hydrophobic areas is in the range of 1.6 to 2.1 mm.

6. The fabric (1) according to claim 1, wherein said hydrophilic agent (15) and/or said hydrophobic agent (14) is thermofixed to the fabric (1) and/or crosslinked.

7. The fabric (1) according to claim 1, wherein said fabric (1) is an elastic fabric that can be stretched up to 100% of its initial length, both in weft and warp directions.

8. The fabric (1) according to claim 1, wherein said hydrophilic agent (15) extends through the body (13) of the fabric (1) and wherein hydrophobic areas (16) extend from said first side (11) into said body (13) of the fabric (1) for a depth (D) ranging from 20% to 70% of the thickness of said body (13).

9. The fabric (1) according to claim 1, wherein said hydrophobic areas (16) extend through said body (13) of said fabric (1) for different depths (D).

10. The fabric (1) according to claim 1, wherein said fabric (1) is a denim fabric.

12. The fabric (1) according to claim 1, wherein said pattern of hydrophobic areas (16) comprises hydrophobic areas (16) having a spiral shape.

13. The fabric (1) according to claim 1, wherein said pattern of hydrophobic areas (16) comprises hydrophobic areas (16) having at least one of the same shape and the same dimension.

21. A garment comprising a fabric (1) according to claim 1.

22. The garment according to claim 21, wherein said pattern of hydrophobic areas (16) comprises hydrophobic areas (16) having at least one of different shapes and different dimensions in different areas of the garment.

23. The garment according to claim 21, wherein the fabric is a denim fabric.

11. The fabric (1) according to claim, wherein said pattern of hydrophobic areas (16) has an irregular distribution.

14. A process for the production of a fabric (1) comprising:

a. providing a fabric (1) comprising a first side (11), a second side (12), and a body (13) extending from said first side (11) to said second side (12),

b. providing at least one hydrophilic agent (15) on at least some regions of said first side (11) of the fabric (1), and

c. providing at least one hydrophobic agent (14) at least on said first side (11) of said fabric (1) as a pattern of hydrophobic areas (16), whereby said first side (11) has a pattern of hydrophobic areas (16) and a pattern of hydrophilic areas (17), to transfer the moisture (30) from said first side (11) to said second side (12).

15. The process according to claim 14, wherein said hydrophilic agent (15) and said hydrophobic agent (14) are applied on a same area of the said first side (11) to provide hydrophobic areas (16).

16. The process according to claim 15, wherein said hydrophobic areas (16) are in the form of a film on the first side (11) of the fabric (1).

17. The process according to claim 15, wherein said pattern of hydrophobic areas is applied to said fabric before the fabric is shrunk by washing.

18. The process according to claim 15, wherein at least one of said hydrophilic agent (15) and said hydrophobic agent (14) is thermofixed and/or crosslinked to the fabric (1).

19. The process according to claim 15, wherein said hydrophilic agent (15) extends through the body (13) of the fabric (1) and wherein hydrophobic areas (16) extend from said first side (11) into said body (13) of the fabric (1) for a depth (D) ranging from 20% to 70% of the thickness of said body (13).

20. The process according to claim 15, wherein said hydrophobic areas are applied to said fabric according to spiral and/or curved lines.
