ABSTRACT:
A hotmelt-adhesive fiber sheet having a high adhesion onto paper, clothes ,timbers, metals, etc. is obtained by subjecting (1) a termpolymer of ethylene-acrylic acid ester-maleic anhydride, from which microfine fibers have not so far been obtained due to inferior spinnability since the terpolymer has a high frictional force against metals and is liable to generate static electricity, and (2) a thermoplastic resin having a melting point higher by 30.degree. C. or more than the melting point of the terpolymer, to conjugate spinning according to a melt blown process, followed by making up the conjugate fibers into a web without using any spinning oiling agent and heat-treating the web.
