The present inventors have analyzed the mechanism of action of the antistatic agent technology of Patent Document 1, and found that a quaternary ammonium salt compound is found on textile products regarding fiber treatment by partial treatment such as spraying or coating. We found that it was not sufficiently diffused.
A water-soluble quaternary ammonium salt having a specific structure is known as a bactericide, and an aqueous composition containing the compound is used as a spray to eliminate unnecessary diffusion in the air or other than the target surface. The spray area during spraying is limited or the quaternary ammonium salt concentration in the aqueous composition is designed to be low. When the concentration of the quaternary ammonium salt is low, the diffusion of the quaternary ammonium salt in the textile product is hardly observed and the spray area is small. Therefore, it is necessary to improve the diffusivity of the quaternary ammonium salt in the textile product. When the quaternary ammonium salt concentration is high, there is almost no effect of diffusion of the textile product. So far, no one has found the problem of diffusion in textile products when the concentration of quaternary ammonium salts is low. Since Patent Documents 2 and 3 consider diffusion one day or several weeks after the solution is immersed in the non-woven fabric, the quaternary ammonium salt is diffused into the textile product in a short time as in the present invention. It does not propose the technical issue.
