Description

[Detailed description of the invention]

The present invention provides clothing suitable for household use that imparts excellent slipperiness to woven and knitted fabrics using synthetic fibers such as nylon fibers, acrylic fibers, polyester fibers, or blended fibers of these synthetic fibers and noodle fibers. Regarding the treatment composition.Slips, stockings, blouses, etc. made of woven or knitted fabrics of synthetic fibers or blended fibers of synthetic fibers and cotton preferably always have a suitable level of slipperiness. "Smoothness" is a tactile evaluation of surface properties, especially frictional properties, which is one of the physical properties of textiles and textiles, and has the same meaning as smoothness, which is one of the basic sensory values of textiles and textiles. . 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. , the feel and comfort of synthetic stockings, and the reduction in sliding friction resistance of synthetic stockings.
This is an extremely important property from the viewpoint of practical functions of textiles and fabrics, such as prevention of "dense". On the other hand, in the textile industry, smoothing agents and the like are used to reduce frictional resistance during the spinning process or the manufacturing process from fiber to finished yarn to finished fabric. 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. However, so far no household finishing agent has been found that meets this purpose. In fields other than household finishing agents, technologies related to imparting slipperiness include the addition of an equivalent or more amount of alkyl sulfate, alkyl ether sulfate, etc. to a cationic surfactant in the field of textile treatment agents. A method is known in which spinning fibers are treated with a liquid in which a cation-anion complex obtained by mixing an anionic surfactant is dispersed using an anionic or nonionic surfactant (
(Special Publication No. 1979-5279). However, this method
Even when 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, for example, there is a composition comprising a cationic surfactant and a non-falling fatty acid salt (Samurai Kaisho Kyuichi 1-ban No. 97 and Dokyu-5
No. 2799), although it was possible to improve the slipperiness to some extent, it was insufficient as a finishing agent for imparting slipperiness. As a result of extensive research in order to obtain a household finishing agent with an excellent effect of imparting slipperiness, the present inventors discovered a composition containing several types of quaternary ammonium salts with similar structures and a long-chain alkyl alcohol. It was discovered that the objective could be satisfied by selectively adjusting the above, and based on this knowledge, the present invention was accomplished. That is, the present invention provides a quaternary ammonium salt and a carbon atom having 12 carbon atoms.

It is necessary to use a mixture in the ratio of 0/1, preferably 40/60, or 60/40. That is, excellent slipperiness can only be obtained by using a mixture within the above range, and when the mixture falls outside of this range, the slipperiness deteriorates. In the present invention, the long chain alkyl alcohol used in combination with the quaternary ammonium salt has 1 carbon number.
2 to 20, so it is usually water-insoluble. Examples of such long-chain alkyl alcohols include lauryl alcohol, cetyl alcohol, n-icosyl alcohol, and the like. The treatment agent of the present invention is prepared by blending the above-mentioned quaternary ammonium salt mixture and long-chain alcohol in a weight ratio of 96:4 to 50:50. The treatment agent of the present invention does not contain the above-mentioned five components, namely, the four components.
It is necessary to contain various quaternary ammonium salts and one type of long mirror alcohol, and if even 11 of these components are missing, good slip properties cannot be obtained. - It was completely unexpected that the combination of the five components greatly 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, and ammonium chloride. It can contain electrolytes, colorants, poppy seeds, optical brighteners, fragrances, and the like. When the treatment agent of the present invention is used at home, the active ingredient in the treatment agent should be
It is desirable to adjust the amount to 2% by weight. When the treatment agent of the present invention is used to treat synthetic fiber products or blended products of synthetic fibers and cotton after washing, it imparts significantly superior slipperiness compared to conventional treatment agents, so it can be used to treat household clothing. It is suitable as an agent. Next, the present invention will be explained in more detail with reference to Examples. The slip properties in each example were tested by the following method. ○} Preparation of samples Commercially available polyester/cotton (weight ratio: 65/35) taffeta, nylon taffeta, and polyester taffeta were repeatedly washed 5 times at 60 qo using a laundry detergent (commercially available) to prepare samples. Next, each of the various treatment agents was diluted with tap water at 25 qC to obtain an aqueous solution with a concentration of 0.067%, and the sample was immersed into this solution at a pressure of 30 degrees and stirred for 3 minutes. After air-drying the sample treated in this way indoors, it was heated at 25°C and 65°C.
It was evaluated after being left for 2 hours under the condition of %RH. [
21 Method for evaluating slipperiness Fold each sample into a rectangle, fold it in half, hold one end in your hand, rub the other end together, and compare the slipperiness with that before treatment. The beach value was determined according to the standards of ◎...Slip property is very good ○...Slip property is good △...Slip property is slightly poor ×...Slip property is poor (before treatment) ) Example 1 Didocosyl dimethylammonium chloride [
