Process for the production of a carboxymethyl cellulose nonwoven fabric and use of a carboxymethyl cellulose nonwoven fabric produced in this way

Process for the production of a porous， wet-laid carboxymethylcellulose nonwoven fabric with a pore size between 1 and 500 ??m， which can be gelled on contact with body fluids or water， the process comprising the following steps: - Chemical treatment of cellulose fibers in an alcoholic solvent in order to produce carboxymethyl cellulose fibers by carboxymethylation of the cellulose fibers; - Detangling or disentangling and mixing of the carboxymethyl cellulose fibers in an alcoholic solution for paper production， which consists of an alcoholic solvent from the group of ethanol， methanol， propanol and mixtures thereof; - elimination of the solvent; and - Carrying out a pressing process by means of calendering after eliminating the solvent. The present invention relates to a method for manufacturing carboxymethyl cellulose wet nonwoven fabrics and a use of carboxymethyl cellulose wet nonwoven fabrics manufactured therefrom. The manufacturing method is a method for manufacturing carboxymethyl cellulose wet nonwoven fabrics by first performing carboxymethylation of cellulose fibers and then performing a paper making process， and enables mass-production due to the convenience and ease of carrying out a process compared with conventional nonwoven fabric carboxymethylation. Additionally， gelation occurs when the carboxymethyl cellulose wet nonwoven fabric manufactured by the manufacturing method above comes in contact with body fluid or water， and thus the carboxymethyl cellulose wet nonwoven fabric manufactured by the manufacturing method of the present invention is useful as medical nonwoven fabrics or mask packs.
