摘要
Microfiber microwebs are provided. The microfiber microwebs have relatively dense nuclei with individual fibers and/or fiber bundles protruding therefrom. The microfiber microwebs can be incorporated into nonwoven webs of blown microfibers, air-laid staple fibers, or wood pulp fibers as well as into shaped articles having porous covering materials. The microfiber microwebs are useful in sorbent, filtration, and thermal insulation materials. The microfiber microwebs are prepared by divellicating a microfiber web to form discrete particles of microfiber microwebs.
