Description

  The present invention relates to a textile treatment agent, a method for imparting tension to a fiber using the same, and a method for reducing wrinkles of the fiber.

  Typical examples of the textile product treating agent used in general households include softeners and pastes. Softeners soften and soften textile products such as clothing, and glues add tension to textile products and give them a feeling close to that of new products. It has been properly used depending on the type of product. However, in recent years, the finish feeling of the softener tends to be favored over the paste, and the demand for the paste tends to decrease year by year. This is thought to be due to the tendency to avoid the crispness, stiffness, etc. of conventional glues. On the other hand, for the diversifying types of clothing, there is a situation where the user's preference cannot be satisfied only by the soft finish feeling of the softening agent. Therefore, there is a strong demand for a finishing agent that finishes a textile product with a smooth texture that feels that cannot be achieved by using only a softener or glue alone, that is, it has tension but is not stiff.

  In addition, clothes such as shirts and polo shirts are formed with washing wrinkles through washing / rinsing / dehydration / drying, and especially wrinkles are formed on clothing mainly composed of cellulosic fibers such as cotton that cannot be worn without ironing. The In recent years, shirts and the like that have been subjected to form stabilization processing have become widespread. However, these effects have been reduced with repeated wearing / washing, and ironing has not been eliminated at all. However, since ironing is one of the most labor-intensive tasks, there is an eager desire for a method that can remove wrinkles as easily as possible without ironing.

  The present inventors disclose a treatment agent that restores the original shape and texture of clothing containing a water-soluble polymer compound, a silicone compound, and a nonionic surfactant in Patent Document 1, Patent Document 2, and Patent Document 3. is doing. However, these technologies use a nonionic surfactant as a stabilizer or an anti-gelling agent, and a specific nonionic surfactant imparts appropriate tension and texture to clothing, and There is no effect of suppressing the formation of wrinkles. In addition to the above prior art, Patent Literature 4, Patent Literature 5, and Patent Literature 6 disclose a technique using a nonionic surfactant as an emulsifier for a silicone compound.

Monoglyceryl ether is generally used as a cleaning agent. For example, Patent Document 7 discloses a liquid cleaning agent containing an alkyl glyceryl ether and having an excellent cleaning effect. However, although it is described that it exhibits excellent cleaning performance against stubborn sebum stains such as collar stains and modified oil stains around the kitchen, there is no description regarding the stability of the silicone-containing composition. In addition to use as a cleaning agent, it is known to be used for cosmetics. For example, Patent Document 8 discloses (a) α-monoalkyl glyceryl ether, (b) waxes, and (c) silicone oil. (D) An oil-in-water emulsified cosmetic containing a hydrophobized powder is disclosed. Here, monoalkyl glyceryl ether is used for the purpose of emulsion stability of silicone oil, but silicone oil is a volatile low-molecular compound that can be used in combination with the stability of high molecular weight polysiloxanes and amino-modified silicones. There is no mention of stability at.
