PROBLEM TO BE SOLVED: To provide a multifunctional regenerated cellulosic fiber in which a carboxyl group is introduced in cellulose without graft polymerization, and to which deodorant properties, washing resistance of deodorant properties, moisture releasing and heat dissipating properties and moisture absorption/release properties are imparted, a fiber structure including the same, and a method for producing them.SOLUTION: The multifunctional regenerated cellulosic fiber includes polyacrylic acid in cellulose. The total content of carboxyl groups is 0.30 to 1.63 mmol/g. The proportion of a content of salt type carboxyl groups is 35% or less to the total content of carboxyl groups. The multifunctional regenerated cellulosic fiber can be obtained by blending an aqueous dispersion including a polyacrylic acid unneutralized compound having a viscosity of 1,000 to 10,000 mPa s and a pH of 1.4 to 2.7 in a viscose dope including cellulose, spinning the prepared viscose liquid for spinning, and adjusting pH so that the pH becomes 6.5 or less as necessary. The fiber structure includes the multifunctional regenerated cellulosic fiber. |
