Abstract
The present invention provides fibers and products produced therefrom, including nonwoven webs and adhesive articles. The fibers, which can be multilayer fibers, include a polydiorganosiloxane polyurea copolymer.
Claims56
A fiber having a diameter of no greater than about 100 .mu.m comprising a polydiorganosiloxane polyurea copolymer as a structural component of the fiber.
A nonwoven web comprising fibers having a diameter of no greater than about 100 .mu.m comprising a polydiorganosiloxane polyurea copolymer as a structural component of the fibers.
An adhesive article comprising a backing and a layer of a nonwoven web laminated to at least one major surface of the backing;
- wherein the nonwoven web comprises fibers having a diameter of no greater than about 100 .mu.m comprising a polydiorganosiloxane polyurea copolymer as a structural component of the fibers.
A release liner comprising a backing and a layer of a nonwoven web laminated to at least one major surface of the backing;
- wherein the nonwoven web comprises fibers having a diameter of no greater than about 100 .mu.m comprising a polydiorganosiloxane polyurea copolymer as a structural component of the fibers.
