Microporous polypropylene fibers were prepared by stretching polypropylene fibers containing CaCO 3 filler. The properties of the resultant fibers are controllable by adjusting the filler content and the stretching ratio. Also, it is elucidated that the fibers have a fine texture of polypropylene fibrils, in which the filler particles are dispersed. Furthermore, the CaCO 3 filler was removed by treating the fibers with an HCl–CH 3 OH solution, and their properties were also investigated. © 1996 John Wiley & Sons, Inc.
