である。The comonomer having an acidic group is a commonly used vinyl monomer having an acidic group which can be copolymerized with acrylonitrile. Specific examples include monomers having a carboxyl group such as acrylic acid, methacrylic acid, and itaconic acid or salts thereof, and monomers having a sulfonic acid group such as allylsulfonic acid and methallylsulfonic acid, and salts thereof. It is preferable that the acrylic fiber contains a comonomer unit having an acidic group in an amount of 1 to 5% by mass, since the later-described crosslinking and hydrolysis reactions are promoted.
