Document Type and Number:
WIPO Patent Application WO/2010/064622
Kind Code:
A2
Abstract:
Provided is a method for manufacturing an ultrafine fiber nonwoven fabric, in which a hollow splittable fiber is prepared by discharging two or more kinds of fiber-forming polymers that are mutually insoluble through one or two slit apertures. The two or more fiber-forming polymers are subsequently interlaced with one another and split. Furthermore, the splittable fiber can preferably be split into 4 to 48 strands, the ratio (L/W) of the slit length (L) to the slit width (W) of each slit aperture is preferably 4 or more, and the slit width (W) of the slit aperture is preferably 0.05 to 0.5 mm and the slit length (L) is preferably 0.2 to 5.0 mm.
