Microfine fiber product and process for producing the same.

摘要

A web is composed of microfine mixed fibers spun according to melt-blown process and comprising high melting point microfine fibers and low melting point microfine fibers having a melting point difference of 10 DEG C or more, the low melting point microfine fibers being present in a proportion of 10 to 90% by weight of the microfine mixed fibers. The web may be converted, by melt action of the low melting point fibers to the high melting point fibers to a non-woven fabric, molded product or, especially, a cylindrical filter.
