Abstract
A thermoplastic fiber demonstrates moisture wicking properties. The fiber has one or more internal lenghtwise open channels each having an opening and at least one groove having a deepest point, a longest dimension and a mouth. The mouth is defined by moving a line from the deepest point along the longest dimension until the largest convex set is identified. The mouth is at the line segment closing the largest convex set. The mouth has width x wherein the average transverse cross-sectional area of the groove is greater than or equal to (.pi.x.sup.2)/8. A durable hydrophilic surface modification is assosiated with said channel.
