The world's only cellulosic continuous filament nonwoven "Bemliese®"

Abstract

In the last 30 years, the market and utilization of cellulosic nonwovens have been remarkably increasing because of progress in productivity and eco-friendship (as a renewable raw material). Most cellulosic nonwovens consist of short fibers from cotton, pulp, viscose, and lyocell that are commonly blended with each other or commodity polymers. In this decade, cellulosic nonwovens are required for some special utilizations such as cosmetics, sanitary products, and medical devices. The world's only cellulosic spunbond "Bemliese®" originated from "Bemberg®", a continuous filament made by cuprammonium solution, invented in the middle of the nineteenth century. "Bemliese®" has some inherent properties which come from the characteristic spinning solution (cuprammonium solution) and sheet-forming technology (wet spunbond process). Recently we have achieved the production of the world's only cellulosic nonwoven made of the finest denier filament.
