  • Nonwoven web and filter media containing partially split multicomponent fibers
    Patent number: 8021996
    Abstract: The present invention provides a nonwoven web prepared from multicomponent fibers which are partially split. The partially split multicomponent fibers have at least one component of the multicomponent fiber separated from the remaining components of the multicomponent fiber along a first section of the longitudinal length of the multicomponent fibers. Along a second section of the longitudinal length of the multicomponent fibers the components of the multicomponent fibers remain together as a unitary fiber structure. In addition, part of the second section of the multicomponent fibers is bonded to part of a second section of an adjacent multicomponent fiber.
