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.

Basic gas absorptive fiber and production thereof

The present invention provides a method of producing a softening agent in which a silicone resin containing particular functional groups, a particular emulsifier and a particular antistatic agent are dispersed stably in an aqueous medium in a particular ratio, and which can give durable slippery touch, softness and processability at the same time to fibers after treatment. The invention also provides an industrially advantageous method of producing acrylic fibers which have animal hair-like touch and processability by one-step treatment, by fixing said softening agent to the acrylic fibers.
