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.
Claims24
A swab constructed to collect and release a biological sample comprising a flock fiber tipped applicator comprised of:
- an applicator;
- and
- flock fibers attached to the applicator, wherein
- the flock fibers are sea-island bicomponent fibers attached to an end portion of said applicator with an adhesive selected from the group consisting of a photocurable acrylic adhesive and a polyurethane adhesive, and wherein
- the bicomponent fibers comprise a first polyester sea material and a second polyester island material, and wherein
- the first polyester sea material has a lower melting point and a greater solubility than the second polyester sea material.
