The present invention is directed to a multi-filament yarn formed at least in part from filaments having cross-sectional zig-zag or double "W" shape with a 180 degree axis of symmetry. The filaments have a denier per filament generally in the range of about 0.1 to about 4.0. Fabrics made from yarns

The present invention is directed to a multi-filament yarn formed at least in part from filaments having cross-sectional zig-zag or double "W" shape with a 180 degree axis of symmetry. The filaments have a denier per filament generally in the range of about 0.1 to about 4.0. Fabrics made from yarns formed with the filaments have high moisture wicking, soft hand, and a silk-like lustrous appearance.

What is claimed is: 1. A fabric formed from a yarn comprising at least in part a synthetic polymer filament, wherein said filament comprises a transverse cross-section that includes seven contiguous segments in zig-zag configuration, wherein each segment defines a proximal end and a distal end, wherein a distal end of a first segment is connected to a proximal end of a second segment, wherein a distal end of the second segment is connected to a proximal end of a third segment, wherein a distal end of the third segment is connected to a proximal end of a fourth segment, wherein a distal end of the fourth segment is connected to a proximal end of a filth segment, wherein a distal end of the fifth segment is connected to a proximal end of a sixth segment, wherein a distal end of the sixth segment is connected to a proximal end of a seventh segment, and wherein a pivot point is defined along the fourth segment and the transverse cross-section of the filament is symmetrical when rotated 180 degrees about said pivot point; and wherein said fabric is a double sided fabric comprising said synthetic polymer filament on one side of said fabric; and further wherein a wetting agent is applied to the one side of said fabric. 2. The fabric of claim 1 wherein adjacent segments of the synthetic polymer filament form an angle between about 40 degrees and about 60 degrees. 3. The fabric of claim 1, wherein the synthetic polymer filament comprises a polyamide synthetic polymer selected from the group consisting of: polyhexamethylene adipamide; polycaproamide; polyenanthamide; nylon 10; polydodecanolactam; polytetramethylene adipamide; polyhexamethylene sebacamide homopolymer; a polyamide of n-dodecanedioic acid and hexamethylenediamine homopolymer; and a polyamide of dodecamethylenediamine and n-dodecanedioic acid. 4. The fabric of claim 1 wherein the synthetic polymer filament has a denier per filament of about 1.0 to about 4.0. 5. The fabric of claim 1 wherein the synthetic polymer filament has an indentation-to-thickness ratio between about 0.25 and about 0.6. 6. The fabric of claim 1, wherein the yarn comprises at least about 50% of the total number of filaments in said yarn of the synthetic polymer filaments. 7. The fabric of claim 1 wherein the yarn formed from the synthetic polymer filaments has a denier between about 15 and about 200. 8. The fabric of claim 1, wherein said wetting agent is selected from the group consisting of a hydrophilic polyamide, hydrophilic silicone, and hydrophilic polyester. 9. A fabric comprising at least in part a synthetic polymer filament having a transverse cross-section having multiple segments arranged in a double "W" shape including a upright W-shaped portion sharing a segment with an inverted W-shaped portion, wherein said fabric is double-sided fabric comprising said synthetic polymer filament on one side of said fabric; and further wherein a wetting agent is applied to the one side of said fabric.
