Title:
METHOD FOR PROCESSING CELLULOSE IN IONIC LIQUIDS, AND FIBERS THEREFROM
Document Type and Number:
Japanese Patent JP2008248466
Kind Code:
A
Abstract:
To provide new processes for producing fibers, which uses a broad spectrum of raw materials, including high purity pulp, where derivatization of the cellulose is not necessary, which are simpler, have less of an environmental impact, and do not have some of the shortcomings of the current processes.
The present application is directed to a process of dissolving cellulose in an ionic liquid, regenerating the fibers and forming a nonwoven web. In particular it is directed to fibers produced from cellulose dissolved in ionic solvents and extruded by the meltblowing process. Bonded nonwoven webs can be obtained in the process.
