Description

[Detailed description of the invention]

The present invention provides a clothing treatment composition suitable for household use that imparts excellent slippage to woven and knitted fabrics using synthetic fibers such as nylon fibers, acrylic fibers, and polyester fibers, or blended fibers of these synthetic fibers and noodle fibers. relating to things. It is preferable that slips, stockings, blouses, etc. made of woven or knitted fabrics of synthetic fibers or blended fibers of synthetic fibers and cotton fibers always have an appropriate slipperiness. "Slide" here refers to the surface properties, especially the frictional properties, which are one of the physical properties of textiles and textiles, which is synonymous with smoothness, which is one of the basic functional quantities of textiles and textiles. It was evaluated. Excellent slipperiness means that, for example, when layered, the covering material retains its form, is adaptable to human body movements, and is smooth when putting on or taking off clothes, etc. ``Densen'' is known for its texture and comfort, and for synthetic stockings due to its reduced sliding friction resistance.
This is an extremely important property from the viewpoint of the practical functions of textiles and fabrics, such as prevention. On the other hand, in the textile industry, smoothing agents and the like are used to reduce frictional resistance during spinning or the manufacturing process from fiber to textile, from spinning to finishing. However, this slipperiness often decreases as clothing is worn and washed repeatedly at home, so there is a need for the development of a means that can be easily used at home and that can impart slipperiness. At present, no household finishing agent has been found that meets this purpose. In fields other than household finishing agents, technologies related to imparting slipperiness include cationic surfactants and anionic surfactants such as alkyl sulfates and alkyl ether sulfates in an equivalent or larger amount. A method is known in which fibers for spinning are treated with a liquid in which a cation-anion complex obtained by mixing a surfactant is dispersed using an anionic or nonionic surfactant (Japanese Patent Publication No. 46-5279). ). However, even if this method is applied as a finishing treatment after washing, the effect of imparting slipperiness does not improve much. On the other hand, as a known softening agent, there are compositions consisting of a cationic surfactant and an insoluble fatty acid salt (JP-A-53-19497 and JP-A-53-19497).
52799), although it was possible to improve the slipperiness to some extent, it was insufficient as a slippery-imparting finishing agent. As a result of intensive research to obtain a household finishing agent with an excellent effect of imparting slipperiness, the present inventors found that 4.
It has been discovered that the objective can be achieved by selectively combining an anionic surfactant with a mixture containing an ammonium salt having a structure similar to that of the species, and based on this knowledge, the present invention has been accomplished.

-Olefins may be sulfonated with sulfur trioxide or hydrolyzed. The treatment agent of the present invention is prepared by blending the mixture of the four types of quaternary ammonium salts described above and one type of anionic surfactant in a molar ratio of 80:20 to 50:50. Even if the molar ratio of the anionic surfactant is smaller than 20 or larger than 50, sufficiently satisfactory slip properties cannot be obtained. Furthermore, the treatment agent of the present invention needs to contain the five types of components described above, that is, four types of quaternary ammonium salts and one type of anionic surfactant.
If even one of these components is missing, good slipperiness cannot be obtained. Thus, it was completely unexpected that the combination of the five components significantly improved the slipperiness. The treatment agent of the present invention has the above-mentioned five types of components as essential components, and in addition, optional components include nonionic surfactants, urea, stabilizers such as propylene glycol, sodium chloride, ammonium chloride, etc. It can contain electrolytes, coloring agents, fluorescent skin thickening agents, fragrances, etc. When the treatment agent of the present invention is used at home, it is desirable to adjust the amount of the active ingredient in the treatment agent to 3 to 20% by weight, taking into consideration the effectiveness of use and dispersibility. The treatment agent of the present invention is a household clothing treatment agent, because when it is used to treat synthetic fiber products or synthetic fiber and cotton blend products after washing, it imparts significantly superior slipperiness compared to conventional treatment agents.
