PRODUCTION OF HIGH STRETCHABLE NONWOVEN FABRIC

PURPOSE:To obtain a nonwoven fabric which is suitable for a hygienic material such as a base for external medicines, because of its high stretchability and flexibility, by passing a web of conjugated fibers having latent crimpability and thermal fusibility through between the hot embossing roll and the flat roll. CONSTITUTION:Conjugated fibers which are composed of at least 2 kinds of polymers different in their melting point and have latent crimpability are used to form web and the web are passed through under pressure between an embossing roll having an incontinuous pattern and the flat roll, both of which are heated at such a temperature as it is higher than the softening point of the low temperature softening polymer, lower than the softening point of the high temperature-softening polymer and higher than the crimp-developing temperature so that the web contacts with the embossing roll or the flat roll in the length of at least 1/5 circumference.
