Method of making sorbent articles

摘要

A method of making a microfibrous sorbent article is provided. The method includes the steps of a) extruding molten thermoplastic fiber-forming polymer from multiple orifices (12) in a fiber-forming die (10), said orifices being aligned along the face of the die; b) attenuating the fibers in a stream of hot air to form a fiber stream of microfibers; and c) collecting said microfibers on a collector (14, 15) having a forming surface, said surface being aligned with said die and substantially parallel to and equidistant from said die such that the fibers form a spirally wound microfibrous sorbent article which is supported on its exterior surface by said forming surface and which is drawn across said forming surface substantially parallel to said die.
