METHOD FOR MANUFACTURING CELLULOSE SOLUTION ORIGINATED FROM UROCHORDA MARINE LIFE SHELLS, AND CELLULOSE FIBER ORIGINATED FROM UROCHORDA MARINE LIFE SHELLS

摘要

The present invention relates to a method for manufacturing a cellulose solution originated from urochorda marine life shells and a cellulose fiber originated from urochorda marine life shells. More specifically, the present invention relates to a method for preparing a cellulose solution originated from urochorda marine life shells, the invention comprising the steps of: (1) preprocessing urochorda marine life shells wherein the washed and dried urochorda marine life shells are alkali treated, thereafter, acid treated and bleached; (2) pulverizing the preprocessed shells by a pin milling method to 10 to 200 mesh and producing into a powder; and (3) dissolving the shell powder in a cellulose solution and homogenizing. The present invention also relates to a cellulose fiber originated from urochorda marine life shells wherein the cellulose fiber can be obtained by extruding and spinning a cellulose solution, which is prepared from urochorda marine life shells, through a spinneret and thereafter by coagulating the spun fiber. According to the present invention, it is possible to prepare a cellulose solution from urochorda marine life shells by economically dissolving cellulose and thereafter, a regenerated cellulose fiber can be manufactured therefrom. Accordingly, it is possible to enhance a utilization rate and create an added value of urochorda marine life shells which are almost entirely discarded.;COPYRIGHT KIPO 2015
