It can be applied by a method such as attaching to the fiber together with the process oil during the fiber production process, adding to the spinning dope in advance, attaching to the fiber in a washing tank, or applying to the surface after forming the fiber product. Of these, a method of attaching the oil together with a process oil in the fiber production process is desirable. This is because the fixing rate of the quaternary ammonium salt to the fiber is good. The quaternary ammonium salt may fall off in the subsequent spinning process in the method of adding to the spinning solution or attaching it in the washing tank, and in the method of applying to textiles, the quaternary ammonium salt may be used when washing etc. Salt may fall off and the antibacterial performance may decrease.

The solvent for dissolving the above-mentioned acrylonitrile-based polymer and spinning is not particularly limited as long as the polymer is dissolved in a concentration at which the polymer can be spun, and organic solvents such as dimethylacetamide, dimethylformamide and dimethylsulfoxide, nitric acid, and the like are used. Examples thereof include concentrated aqueous solutions of inorganic substances such as rodane salt soda and zinc chloride. Organic solvents such as dimethylacetamide, dimethylformamide, and dimethylsulfoxide are preferably used because they are advantageous in forming microvoids in the acrylic fiber yarn before drying and densification described below.

ものである。In the present invention, it is preferable to add a quaternary ammonium salt to the acrylic fiber in a stage called a coagulated yarn, a washed yarn, or a drawn yarn before being dried and densified. This is because it is effective in suppressing the falling off of the quaternary ammonium salt and the deactivation of the antibacterial performance in use environments such as post-processing and washing. Many of the quaternary ammonium salts imparted to the acrylic fiber of the present invention fall off and become inactivated by being incorporated into microvoids and incomplete fiber structures vacated on the surface of the acrylic fiber yarn before being dried and densified. It is controlled and the antibacterial and deodorant properties are maintained.

It is possible. Since the production process can be simplified, for example, it is preferable to use a common solution tank for mixing chitosan and a surfactant containing a quaternary ammonium salt.
