DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article for treating clothes, and more particularly, to an article of clothing having a substrate for carrying a treating agent for clothes which can be transferred to the clothes by contact with the clothes in a laundry dryer. The present invention relates to a clothing treatment product that can impart antistatic properties, flexibility, and the like.

[0002]

2. Description of the Related Art A laundry dryer is generally of a rotary drum type, in which hot air is blown into a rotary drum to give a rotating motion to clothing to remove residual moisture contained in clothing after washing. Is what you do.

[0003] Therefore, clothing is subjected to considerable friction in the dryer, generating a large amount of static electricity. When a hand is put into a rotating drum to take out the clothing, a discharge phenomenon occurs, and an electric shock is given to an operator. . In addition to the above-mentioned shock, the generation of the static electricity causes phenomena such as wrapping when attaching and detaching the dry clothes and adhesion of dust and the like. Furthermore, it is desirable that the clothing be finished with a smooth, soft texture and flexibility.

[0004] From such a viewpoint, it has been practiced to apply a clothing treating agent to clothing during drying to prevent the generation of static electricity and to give the clothing flexibility. Then, as one of the methods, a clothing treatment product in which a clothing treatment agent is supported on an elastic substrate is put into a dryer together with the clothing to be dried and tumbled to transfer the clothing treatment agent to the clothing. A method has been reported (US Pat. No. 3,442,692).

[0005] As the chemicals used in such clothing treatment products, di-long chain alkyl-type cationic activators of compounds widely used in liquid soft finishes and analogous compounds are generally used. . Although these cationic activators have the effect of imparting flexibility to cotton clothing and the effect of preventing static electricity of chemical fibers, they are insufficient for imparting flexibility to chemical fibers.

[0006]

The inventors of the present invention have made intensive studies to overcome the above-mentioned drawbacks and to provide a clothing treatment product having a softening effect on chemical fibers. completed.

That is, the present invention provides a treatment agent for clothing which comprises the following compound (A) as an essential component and which can be transferred to clothing in a laundry dryer upon contact with clothing on a substrate (B) shown below. The present invention provides a clothing processing product. (A) two or three hydrocarbon groups having 11 to 22 carbon atoms in the molecule;
An amine compound having a C00-group and / or a -CONH- group or a neutralized product of an inorganic acid or an organic acid having 6 or less carbon atoms. (B) A sheet-like molded article made of paper or nonwoven fabric.

[0008] Examples of the amine compound used in the component (A) of the present invention include the following.

R ^{9 represents} H, a hydrocarbon having 1 to 3 carbon atoms or a hydroxyalkyl group m; 1 to 3 n; 2 to 3 X; OH, NH ₂ or R ⁷ P; Examples of acids for obtaining the neutralized product of the present invention from these amine compounds include inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid, and phosphoric acid, acetic acid, lactic acid, glycolic acid, and citric acid.
Organic acids having 6 or less carbon atoms, such as maleic acid, may be mentioned.

The component (A) of the present invention is used in an amount of from 20 to 50 based on the substrate (B).
It is preferable that the weight ratio of the obtained clothing treatment product is 5 to 50 g / m ^2, which is carried at 0% by weight. Also, the substrate
As (B), a sheet-like molded article made of paper or nonwoven fabric obtained by a usual method is used.

A known method can be used to carry the clothing treating agent on the substrate.
Examples include a method of dipping in a bath, a spray method, and a printing method. Depending on the type of treating agent used and the method of supporting it, the treating agent is diluted with a volatile solvent such as isopropanol, ethanol or the like for convenience in handling,
After loading on the substrate, an operation of removing the solvent can also be taken.

Further, in order to enhance long-term storage stability, a cellulosic polymer compound such as hydroxypropylcellulose or hydroxypropylmethylcellulose can be added or applied to the substrate surface.

[0016] In addition to the above components, the clothing treatment may contain a fluorescent whitening agent, a fragrance, or silicone for facilitating ironing, etc. in an amount of 0 to 10% by weight.

EXAMPLES The present invention will be described in more detail with reference to the following Examples, but it should not be construed that the present invention is limited thereto.

Examples 1 to 15 Using the component (A) shown in Table 1 and the base (B) shown in Table 2, products for treating clothing were prepared in combinations shown in Table 3. The test samples were prepared by impregnating the various non-woven fabrics shown in Table 2 with the component (A) shown in Table 1 so as to have a concentration of 30 g / m ^2, and measuring 20 cm × 30 cm.
The test sample was cut into cm. Using this, flexibility was evaluated by the following method.

<Evaluation of flexibility> 1 kg of a commercially available cotton towel,
1 kg of acrylic jersey was washed five times with a commercial detergent attack (manufactured by Kao Corporation, registered trademark) in 3.5 ° DH hard water five times (30 liter washing machine), centrifugally dehydrated, and then washed with a Toshiba ED360G clothes dryer. 2 acrylic sweaters, 5 cotton underwear (dry weight approx. 1 kg, 1.7
kg) was dried together with the test sample under the conditions of a capacity of 1200 W and a drying time of 45 minutes. Clothes after drying, 15 ℃, 30% RH
After conditioning for 24 hours in a constant temperature / humidity room, 10 female panelists evaluated the flexibility of cotton underwear and acrylic sweater in the room. The evaluation of the flexibility was performed by a pair comparison using a cloth treated with a test sample in which the substrate (B-1) was impregnated with the same weight of dihydrogenated tallow alkyldimethylammonium methyl sulfate. The evaluation is expressed as follows.

+2; softer than control +1; slightly softer than control 0; same as control -1; control is slightly softer -2; control is softer
