HEAT ADHESIVE COMPOSITE FIBER, NON-WOVEN FABRIC AND NON- WOVEN FABRIC-PROCESSED ARTICLE BY USING SAME

摘要

PROBLEM TO BE SOLVED: To obtain a heat adhesive composite fiber capable of adhering to a highly water-absorbing resin strongly by mixing with the highly water- absorbing resin and performing a heat-treatment for preventing it from falling off, and to provide a formed article by using the same fiber. SOLUTION: This heat adhesive composite fiber used together with a highly water-absorbing resin power or highly water-absorbing resin comprises a low melting component constituted of a modified polyolefin obtained by a grape polymerization with a vinyl monomer including at least one kind selected from an unsaturated carboxylic acid and an unsaturated carboxylic acid anhydride, and a high melting component having a higher melting point by >=15 deg.C than that of the low melting component, and is characterized in that the low melting component forms at least a part of the heat adhesive composite fiber surface continuously in its length direction and the heat adhesive composite fiber gas 0.5-50 denier single fiber fineness.
