Abstract
The invention provides a production method capable of reducing the amount of the chemical liquid (hydrazine and sodium carbonate, etc.) for applying a crosslinking treatment and a hydrolytic treatment, capable of shortening the treatment time, and capable of obtaining crosslinked acrylic moisture absorbing fibers having a sufficient moisture absorbing-moisture releasing performance and provides crosslinked acrylic moisture absorbing fibers. In the case of producing the crosslinked acrylic moisture absorbing fibers by applying a crosslinking treatment and a hydrolytic treatment to acrylic fibers, acrylic fibers made of a copolymer containing from 1 to 5% by weight a comonomer having an acidic group as a comonomer component are used as the raw material fibers to be treated.
