Description of the Related Art Solvent-spun cellulose fibers are produced by an innovative production method in which pulp as a main raw material is physically dissolved in an amine oxide solvent as a sub-raw material, and the cellulose molecules are converted into fibers without breaking the cellulose molecules as much as possible. So, compared to existing cellulosic fibers, such as cotton or rayon produced by the viscose method, it is superior in dry-wet strength and fiber shrinkage, etc., soft and comfortable, and when subjected to friction / rubbing treatment in a wet state The fibers have the property of fibrillating. A number of solvent-spun cellulose fiber products with a unique peach skin-like surface feeling utilizing this fibrillation property have been marketed.However, the generation of fibrils progresses due to repeated washing during wear, causing pilling or fabric surface There is a problem of whitening.

A method for performing a crosslinking reaction with a solvent-spun cellulose fiber is disclosed. However, this method requires a heat treatment to perform a crosslinking reaction, and thus can be processed when the fiber form is a fabric such as a woven fabric or a knitted fabric, but it is very difficult to treat with a cotton or yarn. However, there is a problem that becomes hard.

A fibrillation reduction processing method using a polyfunctional cationizing agent is disclosed. In this method, since an alkali catalyst is used for chemically reacting the polyfunctional cationizing agent and cellulose, if this fibrillation-reducing process is performed after dyeing, the dye is hydrolyzed by alkali and discolored. If the fibrillation reduction process is performed before dyeing, the affinity between cellulose and the dye becomes extremely high, so that it is not possible to dye light colors, and in dark colors, uneven dyeing may occur. There is a problem that it easily occurs.

Preferably, it is 60 to 100 ° C. If the temperature is lower than 40 ° C., the reaction speed becomes slow, so that the processing time becomes longer,
If the temperature is 0 ° C. or higher, reaction unevenness tends to occur.
