摘要： PURPOSE:To dehydrate and concentrate an aqueous carrageenan solution without deteriorating it with superior power consumption efficiency, by providing two cation exchange membranes between an anode and a cathode and further a hydrophilic porous membrane between these cation exchange membranes, introducing successively from the anode side an alkaline electrolyte solution, an aqueous carragenan solution, etc., and applying a voltage between the electrodes. CONSTITUTION:Two alkali-resistant and heat-resistant cation exchange membranes (e.g. perfluorocarbonsulfonic acid membranes) having a cation transference number of 0.95 or more, and an electroendosmosis constant of 20mol. H2O/F or less are provided between an anode and a cathode in an electroendosmosis apparatus or the like, and a hydrophilic microporous membrane having an average pore diameter of 50Angstrom -5mu through which carrageenan cannot permeate but water and ions can permeate is provided between the two membranes. An alkaline electrolyte solution is introduced at least into the anode side, and an aqueous carrageenan solution having a concentration of 0.01-10wt.% is introduced in between the cation exchange membrane on the anode side and the hydrophilic microporous membrane. Then, a voltage is applied between the electrodes so that the DC voltage applied to the aqueous carrageenan solution may be 1-1,000V, and water is removed from between the microporous membrane and the cation exchange membrane on the cathode side to dehydrate and concentrate the aqueous carrageenan solution.

摘要： PROBLEM TO BE SOLVED: To obtain an antimicrobial textile product capable of avoiding deterioration of antimicrobial and deodorizing properties due to various treatments received by the textile product under use environments, excellent in degree of whiteness and color developing clarity and useful for clothes, etc., by including acrylic fibers containing a prescribed amount of a nonelutable antimicrobial agent in a specific mixing ratio. SOLUTION: This antimicrobial textile product comprises acrylic fibers containing 0.05-2.0 wt.% of a nonelutable antimocrobial agent such as a natural antimicrobial agent, e.g. chitosan which is basic polysaccharides prepared by removing calcium carbonate and proteins from a chitinous material forming the outer skeleton of crustaceans such as a crab or a lobster or a shrimp, heating the resultant chitin with a concentrated alkali and deacetylating the chitin in 20-60 wt.% mixing ratio. Furthermore, the bacteriostatic activity value of the antimicrobial textile product is >=2.2. A method for including an acidic aqueous solution of chitosan in a washed yarn prepared by washing a solvent contained in a coagulated yarn in a wet production process for the acrylic fibers, then neutralizing the resultant yarn and washing the chitosan is preferred as the method for including the nonelutable antimicrobial agent.
