摘要： PROBLEM TO BE SOLVED: To provide a monomer-recovering method capable of increasing recovery efficiency of unreacted monomer components recovered in a recovery process of acrylonitrile monomers, and a recovery system of an acrylonitrile polymer. SOLUTION: The monomer components are recovered by vaporizingly separating the monomer components and water from the polymer by distillation of a monomer/polymer/water solution obtained by polymerization in a polymerization reaction tank (5) and subsequently condensing the vaporized monomer components and water, where a deaeration tube part (6) having a tube body (9) of a small diameter is interveningly disposed between the polymerization reaction tank (5) and a distillation column (7) and the polymer/unreacted monomer/water solution obtained in the polymerization reaction tank (5) is continuously fed directly to the distillation column (7) through the deaeration tube part (6). Thus, the amount of AAP (Acrylonitrile Addition Products), formed by the reaction of acrylonitrile (AN) with sodium hydrogen sulfite as a reducing agent for a polymerization initiation reaction and subsequently discharged outside the system, is remarkably decreased thereby to increase the recovery efficiency of AN.

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.
