Acrylic synthetic fibers are widely used in the fields of clothing, bedding and interior. Carpets, curtains, etc. are widely used in rooms with constant temperature and high humidity, where the living environment is becoming more westernized in recent years. It becomes a breeding ground for cockroaches and is said to be a hotbed for ticks. Especially when mites breed,
It is said that the cause of Kawasaki disease, which is a fever that often occurs in infants when carcasses of mites scatter in the air, or that ticks carry anaerobic bacteria that cause Kawasaki disease, has become a social problem. .. Therefore, it has been desired to develop insect repellent fibers such as mites among the fibers.

The method of including DET and / or DMT in the cyclodextrin of the present invention includes, for example, dissolving water-soluble cyclodextrin in water to prepare DET and / or DM.
T is dissolved in methanol, and both equimolar solutions are gradually mixed and stirred. DET and / or DMT are insoluble in water but become a uniform solution when they are included in water-soluble cyclodextrin. Although it may be used as it is, methanol is removed by distillation to protect the environment, and then a surfactant is added.
The surfactant may be one that does not destroy the inclusion state of cyclodextrin and DET and / or DMT and is used as a primary oil before dry densification during the production of acrylic synthetic fibers.

If the temperature is lower than the above temperature, the dry and densification will be insufficient and the physical properties of the fiber, such as whitening of the fiber, defective dyeing color, decrease in strength and elongation, will be serious. Furthermore, the release of the insect repellent becomes large due to insufficient densification of the fibers. In addition, many insect repellents are removed by washing and the like, and the durability of insect repellent performance is poor, which is not preferable.

The insect-repellent acrylic synthetic fiber of the present invention has low toxicity and retains the fiber function and texture of ordinary acrylic synthetic fiber, and even if the insect repellent on the surface of the fiber is washed off by washing, the insect repellent is constantly applied from the inside. It is regenerated on the surface of the fiber by bleeding out, so it does not lose its effect even after repeated washing. Furthermore, it has excellent dyeing resistance.
