Abstract

PURPOSE:To improve the strength of a diaphragm for a speaker by using a foaming agent composed of porous foamed synthetic resin to fuse highly elastic fibers with other materials through the foaming agent and generating firm coupling. CONSTITUTION:To fuse various fiber materials, thermal expansion microcapsules rapping low boiling point solvents with vinyl chloride type resin are mixed into the varias fiber materials and fixed on the fiber materials with macromolecular coagulant. After forming these foamed fiber materials like a diaphragm and drying the sheet, these thermal expansion mirocapsules are foamed at about >=60 deg.C. Thus, the various fiber materials such as highly elastic fibers 1, pulp 2 and synthetic fibers 3 are fused mutually through the foaming agent 4.
