摘要： Disclosed are acidic or basic gas absorptive fiber having both a degree of acidic gas absorption of 70 % or higher and a degree of basic gas absorption of 80 % or higher, and also fabric comprising the fiber. The fiber and fabric, after having absorbed acidic and basic gases, can easily be restored to its original condition if they are exposed to clean air. The fiber is preferably crosslinked acrylic fiber, which has a specific increase in its nitrogen content resulting from crosslinking with hydrazine, a specific amount of carboxyl groups resulting from modification with nitrile groups, a specific ratio of free carboxyl groups to all carboxyl groups existing therein, and a specific equilibrated pH in water, and which is prepared from acrylic fiber through crosslinking with hydrazine, hydrolysis, and conversion of carboxyl groups therein into metal carboxylate groups. The fiber and fabric are durable to cycle use.

摘要： Disclosed herein is a fiber capable of basic gas absorption and easy regeneration. Disclosed also herein is a process for producing said fiber. The basic gas absorptive fiber is an acrylic fiber characterized by a specific amount of nitrogen which is increased by crosslinking with hydrazine, a specific amount of carboxyl groups and amido groups resulting from modification of nitrile groups, and a specific value of tensile strength. It is prepared from acrylic fiber by crosslinking with hydrazine and subsequent hydrolysis and conversion of hydroxyl groups into carboxylic acid. It has good processability and can be used repeatedly.
