Description

The present invention relates to a pest repellent composition for fiber treatment. More specifically, the present invention relates to a pest repellent composition for fiber treatment, which has a good adhesion efficiency of a pest repellent to fibers.

Currently, mosquito-borne infections are a major problem in warm regions such as Southeast and South Asia. There are many mosquito-borne infections without vaccines or remedies, and the only way to protect yourself from these diseases is to prevent them from being bitten by mosquitoes. One means of mosquito control is to wear clothing with a mosquito control function. There are mosquito-proof functional clothing on the market, but there are not many types, and the problem is that what you wear is limited.
In order to obtain a pest repellent effect on general clothing at home, it is conceivable to apply a spray agent containing a pest repellent. For example, in Patent Document 1, a spray agent containing a pest repellent is sprayed on a fiber to determine the pest repellent effect. However, with a spray agent, the spray agent must be sprayed all over the clothes, which is a heavy processing burden to be performed every day. Further, Patent Document 1 does not describe the efficiency of adhesion of the pest repellent to the fiber.

Japanese Unexamined Patent Publication No. 2013-6823

Therefore, the present inventors have attempted to impart a pest repellent effect to clothing by a dipping treatment.
However, the problem is that the efficiency of adhesion of the pest repellent to the fibers is low only by dispersing the pest repellent in the treatment liquid.

The present inventors conducted a study to efficiently attach a pest repellent to clothing, and found that a cationic surfactant and a nonionic surfactant having a specific ethylene oxide chain length were used in combination to obtain a cationic surfactant. It has been found that by keeping the pest repellent in a specific ratio, the adhesion rate of the pest repellent to the fiber is improved.
The present invention relates to, for example, the following [1] to [4].
[1] A pest repellent composition for dipping treatment of fibers.

[2] The pest repellent composition according to the above [1], wherein (A) / (B) is 6.5 or less.
[3] A method for adhering a pest repellent to a fiber, which comprises immersing the fiber in a treatment liquid containing the pest repellent composition according to the above [1] or [2].
[4] A method for preparing a fiber to which a pest repellent is attached, which comprises immersing the fiber in a treatment liquid containing the pest repellent composition according to the above [1] or [2].
