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. Therefore, compared to existing cellulosic fibers such as cotton and rayon produced by the viscose method, it has excellent dry and wet strength and fiber shrinkage, is soft and comfortable, and has a unique surface texture that applies the property of fibrillation. It is known that highly sensitive products having As a method of fibrillating the solvent-spun cellulose fiber, generally, using a liquid jet dyeing machine, an air jet dyeing machine, a washer, etc., the solvent-spun cellulose fiber is wetted with water, rubbed, rubbed, and then treated. A method of performing an enzyme treatment is used. In this method, a solvent-spun cellulose fiber is wetted with water, fibrils are developed in a mechanical abrasion process, and then excess fluff is removed by a cellulase enzyme. Is obtained. However, the fibrillated solvent-spun cellulose fiber-containing fabric currently commercially available only has a product having this surface feeling, and there is a fibrillated product of a solvent-spun cellulose fiber-containing fabric having a different surface texture. It is not at present.

てしまういわゆるフィブリルが発生する。According to the present invention, when a solvent-spun cellulose fiber-containing fabric is subjected to friction and rubbing treatment in an aqueous alkaline solution, the surface obtained by friction with water, rubbing treatment and enzyme treatment is conventionally used. Although the reason why the surface feeling different from the feeling is obtained is not clear, the present inventors speculate as follows. Solvent-spun cellulose fibers, when the cellulose solution is extruded and cooled during spinning, cellulose molecules are crystallized and oriented to form a fiber,
In its structure, thousands of microfibers are bonded by amorphous or non-oriented cellulose "glue" to form one fiber. If strong friction is applied to the fiber while it is sufficiently moistened, the swollen “swollen” part that has absorbed water many times its own weight has reduced its bonding strength.
A so-called fibril, which splits in a branching manner in the fiber axis direction due to the applied stress, occurs.

のであろうと推測する。When an aqueous alkali solution is used to wet the solvent-spun cellulose fibers, the decomposition of the cellulose molecules and the change in the crystal structure are caused by the alkali, and the degree of swelling is increased as compared with the swelling with water. Fibrils of length and thickness develop. For this reason, it is presumed that the surface feeling of the fabric will be wild and casual. On the other hand, those that have been subjected to an enzyme treatment by a conventionally used method lack the fibrils and fluffs generated excessively, and exhibit fibrils of uniform length and thickness, so that they have a feminine tone with an elegant luster. I guess it will be a surface feeling.
