Description

  The present invention relates to a textile product treating agent composition.

Cotton has excellent water absorbency and is excellent in touch, so it is suitably used for textile products such as clothing. Especially in wet seasons during the rainy season and high temperatures in summer, clothing using cotton is preferred because it absorbs moisture such as sweat and creates an environment between clothing and skin. Yes.
However, in cotton that absorbs a large amount of moisture such as sweat, so-called "wetting back" occurs in which the absorbed moisture is re-released onto the skin. Rewetting makes it easier for the clothing to stick to the skin, causing discomfort to the wearer, as well as making the skin surface more susceptible to wiping and further causing friction between the skin and clothing, which may cause skin problems. There is concern about being connected.

A technique using special fibers has been proposed as a technique for suppressing rewetting when wet with sweat or the like.
For example, Patent Document 1 discloses a multi-layered yarn that has less wetting back by having a yarn whose inner layer and / or intermediate layer has a lyocell structure.
In Patent Document 2, the use of a composite spun yarn in which a water-absorbing fiber having improved water retention capability by modifying cellulose filament fiber in the core part and synthetic fiber arranged in the sheath part is used. A technique for leaving no sweat on the contact surface is disclosed.

In addition, a technique for improving the quick drying property of a wet textile product is known.
For example, Patent Document 3 discloses a water-absorbing quick-drying imparting agent composition mainly used as an aerosol product. Specifically, a technique using a polymer having a silicone structure in order to impart quick drying without significantly impairing water absorption is disclosed.
In Patent Document 4, a fatty alcohol having a linear hydrocarbon group having 7 to 11 carbon atoms, an aliphatic alcohol having a branched hydrocarbon group having 7 to 20 carbon atoms, or a mixture thereof is applied to a cotton cloth that directly touches the skin. A method for treating cotton fabric that is attached to impart water diffusion promoting properties is disclosed.
However, these techniques basically have a problem of increasing the drying rate of the textile product, and do not directly solve the problem of wetting back.
Patent Documents 5 and 6 describe softener compositions containing dialkyl quaternary ammonium salts and aliphatic alcohols. However, these patent documents improve the flexibility and antistatic properties against synthetic fibers. However, no consideration has been given to improving rewetting. Patent Document 7 discloses a fabric care agent containing a saturated branched chain alcohol having 8 to 20 carbon atoms as a stabilizer between a delivery enhancer such as a cationic polymer and a fabric softening active substance.

On the other hand, Patent Document 8 discloses an ester group-containing quaternary ammonium type softening agent and a softening agent containing a fatty acid monoglyceride, and Patent Document 9 discloses a dimethyl diester quaternary ammonium type softening agent and a polyvalent compound. Softener compositions containing fatty acid esters of alcohol are described.
Patent Document 10 contains a quaternary ammonium salt having three or more fatty acid ester groups, a polyoxyethylene alkyl ether type nonionic surfactant, and an ester compound of a 3-6 valent polyhydric alcohol and a fatty acid. A softener composition is described.
Furthermore, Patent Document 11 discloses a liquid softener composition containing a specific cationic surfactant and a polyhydric alcohol nonionic surfactant.
These softener compositions have also not been studied at all in terms of improving rewetting.

Japanese Patent Laid-Open No. 10-25638 Japanese Patent Laid-Open No. 62-299534 JP 2005-89882 A JP 2011-122252 A JP-A-56-73173 JP 56-79768 A Special table 2014-510849 gazette Special table 2001-525020 gazette JP-A-8-81881 JP 10-77575 A JP 2003-213568 A

The wetting back suppression technology described in Patent Documents 1 and 2 is difficult to realize at home because special fiber processing is required. The drying promotion method for textile products is achieved by making the moisture absorbed by the textile products easier to wet and spread, and requires time to dry the absorbed moisture. It cannot be said that the problem has been solved.
Therefore, a simple treatment is applied in advance to a textile product containing general cotton fibers, particularly a textile product that is prone to get wet with sweat or the like, such as an underwear, etc. Therefore, development of a textile product treating agent composition capable of suppressing the above-mentioned rewetting is desired.

As a textile product treating agent composition having an effect of suppressing wetting back, the present inventors have a specific tertiary amine compound or quaternary ammonium compound, and an aliphatic alcohol having a linear alkyl group having 12 to 18 carbon atoms. The textile agent processing agent composition using this was found.
However, among quaternary ammonium compounds, quaternary ammonium compounds derived from fatty acid esters of triethanolamine have become world-class general-purpose substrates as flexible substrates excellent in biodegradability. There was room for improvement regarding the anti-wetting effect of the fiber product treating agent composition contained.
Therefore, even when a composition using the above-described triethanolamine fatty acid ester type quaternary ammonium compound having excellent biodegradability is used, a textile product treating agent composition that exhibits an excellent effect of suppressing rewetting. Development is desired.
