Toy articles of manufacture comprising spontaneously wettable fibers

摘要

This invention relates to an article of manufacture consisting of a toy having a plurality of synthetic fibers capable of spontaneously transporting water on the surface thereof, said fibers satisfying the following equation (1-X cos theta a)<0, wherein theta a is the advancing contact angle of water measured on a flat film made from the same material as the fiber and having the same surface treatment, if any, X is a shape factor of the fiber cross-section that satisfies the following equation the fiber and r is the radius of the circumscribed circle circumscribing the fiber cross-section and D is the minor axis dimension across the fiber cross-section.
