Abstract
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.
Claims9
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.
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.
