Abstract: Swabs, materials, and methods of making same, include randomly arranged sea-island bicomponent fibers. According to certain embodiments, swabs and methods of using such swabs are provided so as to collect and release a biological sample comprising a flock fiber tipped applicator wherein the flock fibers are sea-island bicomponent fibers attached to an end portion of the applicator with an adhesive selected from the group consisting of a photocurable acrylic adhesive and a polyurethane adhesive, the bicomponent fibers being structurally stable in water and the sea component of the bicomponent flock fibers being intact.

Abstract: Swabs, materials and methods of making the same include randomly arranged sea-island bicomponent fibers which have randomly splayed terminal ends. According to certain embodiments, swabs are provide which include an applicator, and sea-island bicomponent fibers attached to the applicator, wherein at least about 70% of the fibers comprise randomly splayed terminal ends of the islands of said bicomponent fibers along a length of about 45% or less from said ends, and wherein the bicomponent fibers comprise 10-3000 island parts per fiber.
