20110008620 | Fiber with 4T cross section - The present invention relates to a fiber with 4T cross section, comprising four T-shaped lobes, each of said T-shaped lobes having a cap portion and a leg portion, the leg portion of each of said lobes intersecting at the center of the fiber, each of said lobes separating from each other, and the adjacent T-shaped lobes forming an open hollow portion. Moreover, parameters such as Denier, opening range of the hollow portion, hollowness ratio, and degree of variation of the cross section are specifically defined. The fiber of this invention has guide channels design and thus can preserve relatively large clearances. Accordingly, the fabrics woven by the fiber of this invention have the outstanding capabilities of absorbing moisture and relieving sweat and the effect of keeping warm without creating a muggy feeling. | 01-13-2011 |
