Abstract

PURPOSE: To enable direct electretization by one-time corona discharge using a single corona discharge device by a method wherein a fibrous material consisting of a regular-slitted drawn film and capable of exhibiting a network structure when expanded widthwise is lelectretized.
CONSTITUTION: A fibrous material consisting of a regular-slitted drawn film, tape, or strip of a thermoplastic polymer and capable of exhibiting a network structure when expanded widthwise, is electretized. Upon forming of the slits, the regular- slitted drawn film, tape, or strip is fibrous material capable of being spread into a network structure; at the same time, it still retains the form of a film, so that it can be electretized in the same manner as an ordinary film, without such phenomena as dielectric breakdown.
