Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a household clothing finishing agent that has an excellent effect of imparting slip properties and antistatic properties to knitted fabrics made of cotton and synthetic fibers.

Secondary textile products made from knitted fabrics of cotton and synthetic fibers such as acrylic fibers, nylon fibers, and polyester fibers, such as blouses, slips, and stockings, are commercially available with appropriate slip and antistatic properties. .

"Slip property" here is synonymous with "smoothness", which is one of the basic properties of striped fabrics, and refers to surface properties, especially friction properties, which are one of the physical properties of knitted fabrics. The evaluation was based on tactile sensation.

Excellent slip properties mean, for example, that when layered, the covering material retains its covering form, is adaptable to human body movements, is smooth when worn, and is smooth when putting on and taking off clothes. That is, specifically,
For underwear, it means that it has a good feel and is comfortable to look at, and for synthetic stockings, it means that it can prevent ``dense'' due to a reduction in sliding friction resistance. Therefore, "slip property" is an extremely necessary property from the standpoint of practical functionality of knitted fabrics. However, if textile products are worn and washed repeatedly at home,
The slip properties and antistatic properties both tend to decrease significantly.

Therefore, there is a desire to develop a finishing agent that can be easily used at home and has the effect of imparting slip properties and antistatic properties, but no finishing agent has yet been found that satisfies these demands.

On the other hand, quaternary ammonium salts such as di-long-chain alkyl di-short-chain alkyl (or hydroxy short-chain alkyl) ammonium salts and polyoxyethylene alkyl sulfate or Q
- Complexes with olefin sulfonates, that is, complexes between quaternary ammonium salts and anionic surfactants, are known (U.S. Pat. No. 3,920,563, U.S. Pat.
20565 specification, Tokusekki No. 53-5279y, etc.).

The present inventors focused on a complex of this quaternary ammonium salt and an anionic surfactant and investigated the effect of imparting slip properties and antistatic properties, and found that in this type of complex, quaternary It was found that the molar ratio of ammonium salt to anionic surfactant greatly influences the physical and chemical properties. In other words, when the quaternary ammonium salt is in large excess compared to the anionic surfactant,
Almost no effect of imparting slip properties or antistatic properties to synthetic fiber products can be expected, and only an effect of imparting slip properties to cotton products can be expected. If the amount of quaternary ammonium salt is slightly excessive (approximately 55:45), a certain degree of slip property imparting effect and antistatic property imparting effect to synthetic fiber products can be expected, but the quaternary ammonium salt has no slip property imparting effect to cotton products. It is inferior to the case of large excess. If the anionic surfactant is in excess, no effect of imparting slip properties or antistatic properties to cotton products and synthetic fiber products can be expected. From the above study results, it has been found that a very limited ratio of quaternary ammonium salt and anionic surfactant can provide a certain degree of slip and antistatic properties to synthetic fiber products and cotton products. .

However, in order to be a household clothing finishing agent aimed at imparting slip properties and antistatic properties to both cotton products and synthetic fiber products, the proportion of the quaternary ammonium salt and anionic surfactant described above must be The effects obtained by adjusting and subtracting are still insufficient.

The inventors of the present invention have conducted intensive research to develop a household clothing finishing agent that exhibits excellent slip properties and antistatic properties for both cotton products and synthetic fiber products. a particular quaternary ammonium salt mixture of;
When polyoxyethylene alkyl sulfate, Q-olefin sulfonic acid, or their salts are sewn together with a long-chain alkyl alcohol, it has a surprising effect of imparting slip properties and charging to both cotton products and synthetic fiber products. It was discovered that the inhibitory effect is exerted, and the present invention was completed based on this knowledge.

If only the component as a quaternary ammonium salt is used and the component (B) is omitted, the effect of imparting slip properties and the effect of imparting antistatic properties to synthetic fibers will be reduced, making it impossible to achieve the object of the present invention. Further, even when the [D' component is omitted, the same excellent effect of imparting IJ slip properties and antistatic properties cannot be expected. That is, the sail,

By combining each component, the present invention has a synergistic effect. The purpose of this invention is to exhibit excellent slip properties and antistatic properties for textile products, both cotton fibers and synthetic fibers. By the way, in order to fully express this excellent effect, the ratio of each component is important.

It is an aqueous dispersion containing the four ingredients in the proportions mentioned above, and the concentration is within the range of 3 to 2% by weight based on the total amount of the four ingredients. Desirable from the viewpoint of effectiveness and dispersibility. In addition to the above-mentioned four ingredients, the household clothing finishing agent of the present invention optionally includes a nonionic activator, a stabilizer such as urea and propylene glycol, an inorganic electrolyte such as common salt and ammonium chloride, an organic electrolyte, and a colorant.

The test method for the household clothing finishing agent in each example is as follows.

[1] Finishing method Commercially available cotton towels, polyester jersey, and nylon tricot were washed 5 times at 60 oo using laundry detergent (commercially available) and used as test cloths.

Next, the clothing finishing agent shown in each example is diluted with 2,500 ml of tap water to give a concentration of 0.067%, and the test cloth is immersed in this solution at 3 pitches and stirred for 3 minutes.

After the fabrics treated in this way were air-dried indoors, those for evaluating slip properties were left at 2,500 and 65% RH for 2 hours, and those for evaluating antistatic properties were left at 2,500 and 65% RH for 2 hours.
The samples were left for 7 hours under the condition of 46% RH and used for each test. (2) Evaluation test: Fold the slip property test fabric into a rectangle, then fold it in half, hold one end in your hand, and rub the other end to compare the feeling of slippage with that before treatment. Evaluate according to the criteria.
