  In order to obtain a fiber treatment agent, the above-mentioned components are appropriately selected, mixed in a dry ratio or a wet ratio at a predetermined ratio, and stirred until uniform according to a conventional method, and then necessary pH adjustment and drying treatment are appropriately performed. Just do it.

  Examples of the object to which the fiber treatment agent is applied include paper, fibers, and sheet-like materials made of them. The term “paper” as used herein refers to a paper having a flat shape or a flat plate shape formed by entanglement of fibrous materials and rich in flexibility. For example, tissue paper, toilet paper, paper towel, paper diaper, paper napkin, sanitary paper, dust paper, Kyoto paper, wiper and the like can be mentioned.

  Examples of the fibers include, but are not limited to, animal hair such as wool, synthetic fibers such as rayon, cotton, acrylic, polyester, and nylon, or blended fibers themselves, and fibers made of these fibers. Since the effect of the treatment with the agent is great, it is more preferably any of cellulose fibers such as cotton / hemp and pulp, regenerated cellulose fibers such as rayon / cupra / polynosic, and protein fibers such as wool / silk. The form of these fibers is arbitrary, and may be a single yarn or woven fabric, and may be a coat, sweater, shirt, muffler, shawl, clothes, etc., various linings, duvets, blankets, stuffed animals, carpets, etc. There may be.

  The sheet-like material is a sheet-like material obtained by further processing paper or fiber, for example, woven fabric, knitted fabric, nonwoven fabric, felt, quilted cotton sanded with nonwoven fabric, etc., cotton sheet-like Can be mentioned.

  The amount of the fiber treatment agent applied to paper or the like is not particularly limited, but in general, the solid content is preferably 0.01 to 50% by mass with respect to paper or fiber, or a sheet-like material composed of them. However, the application amount can be appropriately determined according to the purpose, application, and material.

  There are no particular restrictions on the method used when applying the fiber treatment agent to paper or the like, and various methods can be taken. For example, a fiber treatment agent is impregnated with an impregnation machine (bath) in a manufacturing process of paper or fiber, or a sheet-like material made of them, or a finished paper, or sprayed with a sprayer, or with a coating machine. It can also be used by applying or kneading or adhering with a roll or the like. Alternatively, it can be kneaded and spun into a molten polymer, used in a method in which it is dissolved or dispersed in a spinning bath and adhered at the time of spinning, or used as a fiber finishing oil after spinning, Furthermore, the method of heat-processing after attaching a processing agent and drying can also be used.

  In particular, in fibers obtained by wet spinning, such as regenerated cellulose fibers such as cupra and rayon, the treatment agent is mixed with the spinning dope, dissolved or dispersed in the spinning bath, and the fiber after spinning is dissolved in the treatment agent. It is also possible to take a method of immersing in a treatment bath.

  Paper, fibers, and sheet-like materials obtained using the fiber treatment agent have a moist feeling without stickiness, and are excellent in smoothness after use and good conformity to the skin. In addition, since the fiber treatment agent is extremely hypoallergenic and excellent in safety, it is particularly useful in applications that directly contact the skin or the like.

While this solution was adjusted to a pH range of 10 to 11 with a 25% aqueous sodium hydroxide solution and the reaction temperature was maintained at 5 ° C., 31.1 g of N-lauroyl-L-glutamic anhydride (0. 1 mol) was added over 2 hours to carry out the reaction. After stirring for another 30 minutes, tertiary butanol was added to a concentration of 20% by weight in the liquid, 75% sulfuric acid was added dropwise to bring the pH value of the liquid to 2, and the liquid temperature to 65 ° C. It was adjusted. After completion of the dropwise addition, stirring was stopped, and the mixture was allowed to stand at 65 ° C. for 20 minutes. Tertiary butanol and water were added to the separated organic layer, the temperature was raised to 65 ° C., and the mixture was stirred for 20 minutes. After the stirring was stopped, the mixture was allowed to stand to separate into an organic layer and an aqueous layer. After repeating the same washing operation with respect to the obtained organic layer, the solvent was removed from the obtained organic layer and neutralized with sodium hydroxide to an aqueous solution having a solid content of 30% by weight and a pH of 6.7 (25 ° C.). After the preparation, this was dried to obtain a composition containing an acyl compound represented by the formula (4).
