Description

  The present invention relates to a harmful arthropod-controlling fiber, a method for producing the same, and a textile product using the fiber.

  Leopard mites such as Kona Leopard Mite and Yake Leopard Mite have their parasites, carcasses, feces, etc. as causative agents of allergies and cause various harms such as atopic dermatitis and asthma. In addition, crawfish mites such as southern ticks and stag beetles breed on leopard mites and mites, and often sting people. The house host of the house dust mite is a mouse or a bird, but the mite that crawls out sucks and sucks a person. In order to control these mites, it is common to formulate harmful arthropod control compounds such as acaricides and insecticides in aerosols, smoke agents, etc., and treat them at the place where mites are generated. (For example, refer nonpatent literature 1).

Many harmful arthropod control compounds are known, among which etoxazole ("2- (2,6-difluorophenyl) -4- (2-ethoxy-4-tert-butylphenyl) -2-oxazoline" It is known that dihydrooxazole-based compounds represented by) exhibit excellent control activity against mites (see, for example, Non-Patent Document 1).

[Wherein, X represents a halogen atom or a methyl group, Y represents an alkyl group, an alkoxy group, a methyl mercapto group or a halogen atom, and m and n each independently represents an integer of 0 to 5]
The raw fiber is infiltrated into an aqueous emulsion containing a harmful arthropod control compound having a structure represented by the following formula, and then the fiber is dried.

  According to the said method, the harmful arthropod control fiber which can be arrange | positioned in the place where the harmful arthropod represented by the mite is easy to live can be manufactured. Furthermore, since the harmful arthropods have the controllable fiber harmful arthropod control compound firmly adhered to the fibers, their medicinal effects are maintained for a long time.

  As described above, the harmful arthropod controlling fiber according to the present invention is a raw fiber in a water emulsion containing a binder resin and a harmful arthropod controlling compound having a structure represented by the general formula (1). It is characterized by being obtained by dipping the fiber and then drying the fiber.

  For this reason, since the harmful arthropod controlling compound is adhered to the fiber surface together with the binder resin, it can be placed in a place where harmful arthropods typified by ticks are liable to live. Harmful arthropods such as mites are liable to live in dark and humid places such as the inside and back of carpets, inside tatami mats, and inside futons, so place the fiber of the present invention in such places. Thus, it can be efficiently controlled. In addition, since the harmful arthropod control compound is firmly attached to the fiber surface, this medicinal effect is sustained for a long time.

  Therefore, according to the above configuration, the harmful arthropod control compound represented by ticks can be placed in a place where it is easy to live, and the harmful arthropod control compound can maintain the efficacy of the harmful arthropod for a long period of time. There exists an effect that a foot animal controllable fiber can be provided.

  The present invention will be described in detail below. Note that “A to B” indicating a range means A or more and B or less.

  The harmful arthropod controlling fiber according to the present embodiment has the following general formula (1) on the raw fiber surface.

[Wherein, X represents a halogen atom or a methyl group, Y represents an alkyl group, an alkoxy group, a methyl mercapto group or a halogen atom, and m and n each independently represents an integer of 0 to 5]
It is obtained by adhering a harmful arthropod control compound having a structure represented by the above together with a binder resin.

  In the general formula (1), X is a halogen atom or a methyl group. As said halogen atom, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, etc. are mentioned, More preferably, it is a fluorine atom.

  In the general formula (1), Y is an alkyl group, an alkoxy group, a methyl mercapto group, or a halogen atom. The alkyl group is preferably a linear or branched alkyl group having 1 to 6 carbon atoms, and specifically includes a methyl group, an ethyl group, a propyl group, a butyl group, and a t-butyl group.

In the present invention, the “water emulsion” means a binder resin and / or the compound dispersed in water in an emulsified state or a suspended state.

  The harmful arthropod controlling compound is not normally emulsified or dispersed in water as it is. For this reason, it is usually used after preparing a suitable formulation containing a surfactant (e.g., an organic solvent if necessary) such as an emulsion or suspension, and then diluting it in water. In addition, since the binder resin is not emulsified or suspended in water as it is, a concentrated liquid containing a surfactant (and an organic solvent if necessary) such as an emulsion and a suspension is similarly diluted with water.

  When the raw fiber is immersed in a water emulsion containing the binder resin and the harmful arthropod control compound, the concentration of the harmful arthropod control compound with respect to the raw fiber is 0.001 to 0.5%. It is preferable to be within the range of owf (owf is an abbreviation of on the weight of fiber), and more preferably within the range of 0.001 to 0.1% owf. The concentration of the binder resin relative to the raw fiber is usually preferably in the range of 0.01 to 10% owf, and more preferably in the range of 0.01 to 1% owf. The above-mentioned “% owf” generally means the mass% of the amount of dyes and auxiliaries used in the dyeing process (for example, “Dyeing Dictionary”, March 25, 1982, Asakura Shoten) In this specification, it means the mass% of the active ingredient (in the above case, harmful arthropod control compound or binder resin) with respect to the mass of the raw fiber.

  The main arthropod pests to be controlled are leopard mites such as leopard mite and mushroom mite, tick mites such as southern mite and staghorn tick, mite mites such as mite mite, and mites such as house mites. Insects that directly damage fibers and fiber products, such as moths and cutworms. Furthermore, insects such as fleas, cockroaches, termites, and aphids, and arthropods such as centipedes, geese, and rubber bugs can be controlled.

  The harmful arthropod controlling fiber according to the present embodiment can be used for any product, but is preferably cotton, thread, fiber sheet or the like. As a fiber sheet, a nonwoven fabric, a textile fabric, a knitted fabric etc. are mentioned, for example. Specific product applications include carpet fabrics, vehicle interior materials, interior materials (chair upholstery, chair cushion materials, curtains, wallpaper, etc.), tatami mat interior sheets and futons, stuffed animals, cushions and other packed objects. Applicable to batting etc.

  The method for producing harmful arthropod control fibers according to the present embodiment includes a binder resin and the following general formula (1):
