ABSTRACT:
A method for manufacturing a fiber aggregate formed by fiber having reforming surface comprises the 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 the surface, and a second portion having interfacial energy different from that of the hydrophilic group, and interfacial energy substantially equal to the surface energy of the fiber; orientating the second portion toward the fiber surface, while orientating polymer to the side different from the surface of the first group; and forming a fiber absorber by heating the fiber having the reformed surface in the step of orientating polymer to thermally bond the contact points of fibers themselves. With this method of manufacture, it becomes possible to enhance the uniform property of the fiber aggregate still more, which is formed subsequent to making the property of such fiber aggregate uniform per unit of single fiber or small aggregate existing in any one of stages before the formation thereof.
