Abstract:
1. A method for manufacturing a fiber aggregate formed by fiber having reforming surface, comprising the following steps of: providing a fiber surface having thermoplastic resin at least on the surface layer thereof with a hydrophilic processing liquid containing polymer having a first portion with more hydrophilic group than said surface, and a second portion having interfacial energy different from that of said hydrophilic group, and interfacial energy substantially equal to the surface energy of said fiber; orientating the second portion toward said fiber surface, while orientating polymer to the side different from the surface of the first group; and forming a fiber absorber by heating said fiber having the reformed surface in said step of orientating polymer to thermally bond the contact points of fibers themselves; and providing a catalyst for cleaving polymer in said processing liquid, wherein said polymer is cleaved into subdivided polymer on the surface of said portion by the utilization of said catalyst for cleaving polymer.
