  However, the conventional pest repellent clothing described above, in particular, the pest repellent clothing (fishing clothes) subjected to chemical treatment has the following problems.

  In other words, the chemical treatment method is basically performed by immersing the fabric in a repellent treatment solution, so the thickness of the coat layer due to the treatment solution adhering to the surface of the fabric must be thin. . Therefore, for general clothing, there is not much different from the method of spraying treatment liquid with repellent effect by spray method, and the repellent effect cannot be maintained for a long time, and the coat layer is solidified by drying Therefore, it is not possible to sufficiently generate odors which are harmful to pests. Eventually, there was room for further improvement from the practical viewpoint of ensuring sufficient repellent performance and sustaining for a long period of time.

  The object of the present invention is to provide a pest repellent garment and a method for producing the same that solve the problems in the background art.

  In order to solve the problems described above, the pest repellent garment 1 according to the present invention is configured to at least friction when constituting a pest repellent garment that prevents a pest from approaching by applying a predetermined pest repellent treatment to the clothing fabric 2. A plurality of microcapsules 3 in which a liquid pest repellent 3d is encapsulated inside a capsule wall 3s made of synthetic resin Rs generated in a breakable manner by attaching to the surface of the fiber material 2g constituting the garment fabric 2, and It is characterized by being distributed on the surface of the clothing fabric 2.

  On the other hand, in order to solve the above-described problem, the method for manufacturing a pest repellent clothing according to the present invention manufactures a pest repellent clothing that prevents a pest from approaching by applying a predetermined pest repellent treatment to the clothing fabric 2. At this time, the clothing is so arranged that a large number of microcapsules 3... In which a liquid pest repellent 3d is sealed inside the capsule wall 3s made of synthetic resin Rs that can be broken at least by friction are distributed on the surface of the clothing fabric 2. It is made to adhere to the surface of the fiber material 2g ... which comprises the fabric 2.

  In this case, according to a preferred aspect of the invention, the synthetic resin Rs can be the first synthetic resin Rs1 as the first crosslinking agent and the second synthetic resin Rs2 as the second crosslinking agent.

Further, the size of the microcapsules 3 can be selected in the range of 1 to 500 [nm], and the durability of the microcapsules 3 can be adjusted by selecting at least the size.

  According to the pest repellent garment 1 and the method for manufacturing the same according to the present invention, the following remarkable effects can be obtained.

  (1) When the pest repellent clothing 1 is attached to the body, the capsule wall 3s of the microcapsule 3 is broken by friction caused by the movement of the body, so that the internal pest repellent 3d is released to the outside, and the clothing fabric 2 adheres to the surface of the fiber material 2g. Since the microcapsules 3 are ruptured randomly according to the position and size of friction, the repellent effect of the pest repellent 3d can be maintained for a long period of time.

  (2) Every time the microcapsule 3 breaks, a new liquid pest repellent 3d is released and adheres to the surface of the fiber material 2g in the clothing fabric 2, so that it is always sufficient while the microcapsule 3 remains. Can be provided as a pest repellent garment 1 with high practicality, such as ensuring high repellent performance (initial performance).

  (3) According to a preferred embodiment, if the first synthetic resin Rs1 as the first crosslinking agent and the second synthetic resin Rs2 as the second crosslinking agent are used as the synthetic resin Rs, the first synthetic resin Rs1 and the second synthetic resin Since both characteristics of Rs2 can be combined, it is possible to easily ensure sufficient adhesion performance and appropriate breaking performance of the microcapsules 3 to the fiber material 2g by selecting the blending ratio and the like.

The flowchart for explaining the manufacturing process of the pest repellent clothing according to a preferred embodiment of the present invention step by step, The schematic diagram which shows the state which the microcapsule adhered to the fiber material of the insect repellent clothing which concerns on suitable embodiment of this invention, Action diagram of the pest repellent clothing, Use illustration of the pest repellent clothing, Other usage illustrations of the pest repellent clothing,

  Next, preferred embodiments according to the present invention will be given and described in detail with reference to the drawings.

  First, the manufacturing method of the insect repellent clothing 1 which concerns on this embodiment is demonstrated concretely with reference to FIGS.

  The pest repellent garment 1 according to the present embodiment includes a clothing fabric 2 and a number of microcapsules 3 attached to the clothing fabric 2 as basic components. In this case, the garment fabric 2 is a garment to which the microcapsules 3... Are not attached, which is the same as a general garment. In addition, the kind of pest repellent garment 1 is not particularly limited, and can be applied as long as it is basically worn on the user's body and uses a fiber material. Therefore, various garments such as a jacket, a spong, a hat, socks, an arm cover, a foot cover, and a neckerchief can be applied. The clothing fabric 2 may be a commercially available clothing as it is, or may be produced as a dedicated clothing fabric 2 for obtaining the pest repellent clothing 1.

Further, the following substances are used as basic generation materials (raw materials) for generating the microcapsules 3.
Pest repellent 3d (main agent): Toluamide complex compound
First synthetic resin Rs1 (first crosslinking agent): acrylic resin
Second synthetic resin Rs2 (second crosslinking agent): urethane resin

  In this case, as the toluamide complex compound used for the pest repellent 3d, for example, DEET (N, N-diethyl-m-toluamide), which is widely known as a repellent for repelling pests, can be used. This pest repellent 3d becomes the core substance of the microcapsule 3. In addition, DEET is only shown as an example, and various substances having a pest repellent effect including various toluamide complex compounds can be used. Since the acrylic resin can obtain a wide range of physical properties from a rubber-like elastic body to a hard resin depending on the type of the side chain R of the acrylate ester used as a raw material, the first cross-linking agent (the first cross-linking agent for generating the capsule wall 3s of the microcapsule 3) Most suitable as one synthetic resin Rs1). Since the urethane resin has high substrate adhesion, it is optimal as a second cross-linking agent (second synthetic resin Rs2) for generating the capsule wall 3s.

  As described above, when the first synthetic resin Rs1 serving as the first crosslinking agent and the second synthetic resin Rs2 serving as the second crosslinking agent are used as the synthetic resin Rs, both the first synthetic resin Rs1 and the second synthetic resin Rs2 are used. Since the features can be combined, it is possible to easily ensure sufficient adhesion performance and appropriate breaking performance of the microcapsules 3 to the fiber material 2g by selecting the blending ratio and the like. In particular, if an acrylic resin is used as the first synthetic resin Rs1 and a urethane resin is used as the second synthetic resin Rs2, sufficient adhesion performance to the fiber material 2g of the above-described microcapsules 3 and appropriate breakage performance are obtained. There is an advantage that can be implemented as an optimum form from the viewpoint of ensuring.

  Next, the manufacturing procedure of the pest repellent clothing 1 will be described with reference to the flowchart (process diagram) shown in FIG.

  First, the pest repellent 3d as the main agent is prepared (step S1). In this case, the toluamide complex compound as a raw material is well dissolved in water at room temperature, and then poured into a solution (water) to obtain a prepared solution. Then, this prepared solution is uniformly mixed by a predetermined mixing means (step S2). At this time, the liquid temperature of the prepared solution is adjusted to about 25 [° C.] (step S3). Thereby, the pest repellent 3d used as a core substance can be obtained.

  Next, the garment fabric 2 to be processed is put into the preparation solution obtained in step S3, that is, the pest repellent 3d (steps S4 and S5). Then, a stirring process is performed by a predetermined stirring means (step S6). This stirring process is performed for approximately 10 minutes after the garment dough 2 is introduced. On the other hand, the production | generation process liquid for producing | generating a microcapsule is prepared by mixing the acrylic resin (1st synthetic resin Rs1) used as a 1st crosslinking agent, and water (step S7). Moreover, the production | generation process liquid for producing | generating a microcapsule is prepared by mixing the urethane resin (2nd synthetic resin Rs2) used as a 2nd crosslinking agent, and water (step S8). In this case, the ratio of the acrylic resin generation treatment liquid and the urethane resin generation treatment liquid can be appropriately adjusted between 20:80 and 80:20.

  Each of the production processing solutions that have been prepared is sequentially put into the pest repellent 3d in which the clothing fabric 2 is accommodated. Then, a stirring process of stirring for approximately 10 minutes is performed (steps S9 and S10). When the stirring process is completed, a temperature increasing process is performed to obtain a temperature gradient that increases by 1 [° C.] over 1 [minute] (step S11). That is, heat treatment is performed by a predetermined heating means, and temperature control is performed by a feedback control method so as to obtain the temperature gradient, and the temperature is increased to 45 [° C.]. In this case, the temperature raising process time is approximately 20 [minutes]. When this temperature raising process is completed, stirring is performed for about 15 minutes while maintaining 45 [° C.] (steps S12 and S13).

  In the above process, the microcapsules 3 are generated. That is, the pest repellent 3d is dispersed in the generation treatment liquid as small microdroplets, and the microdroplets are covered with the capsule wall 3s by the generation treatment liquid of the acrylic resin and the urethane resin so that the microdroplet becomes a core substance. Processing is performed. As a result, a large number of microcapsules 3... In which a liquid pest repellent 3 d is sealed inside the capsule wall 3 s that can be broken at least by friction are generated, and the generated microcapsules 3 constitute a clothing fabric 2. A large number of microcapsules 3 are evenly distributed on the surface of the garment fabric 2.

  FIG. 2 schematically shows a state in which the microcapsules 3 are attached to the fiber material 2g. The size of the microcapsules 3... Obtained under the exemplified generation conditions is in the range of 1 to 500 [nm]. Thus, if the size of the microcapsules 3 is selected within the range of 1 to 500 [nm], the action effect by the pest repellent clothing 1, that is, the repellent effect against the pest is maintained over a long period of time, and always sufficient repellent. From the viewpoint of securing performance (initial performance), it can be implemented as an optimum form. FIG. 3 shows a cross-sectional form of the microcapsule 3, which is substantially a sphere. Therefore, the diameter of the microcapsules 3 becomes the size of the microcapsules 3.

  By the way, the size of the microcapsules 3 can be selected by setting processing conditions such as temperature conditions and stirring conditions when the microcapsules 3 are generated. That is, if the microcapsules 3 are selected to be large, the microcapsules 3 are easily broken, so that the durability can be shortened (smaller). On the other hand, if the microcapsules 3 are selected to be small, the microcapsules 3 are difficult to break, so that the durability can be increased (high). Thus, the durability can be easily adjusted by selecting at least the size of the microcapsules 3. Thereby, since the repellent performance and the lasting performance with respect to the pest in the pest repellent clothing 1 can be set arbitrarily, there is an advantage that the repellent performance and the lasting performance can be easily optimized according to the kind and use of the pest repellent clothing 1. In addition, by appropriately setting processing conditions such as temperature conditions and stirring conditions when the microcapsules 3 are generated, the amount of the microcapsules 3 generated and other physical properties can be easily adjusted.

  When the above process (stirring process) is completed, a dehydrating process is performed (step S14). In this case, complete dehydration is not performed, and dehydration of about 80% is performed. Therefore, about 20% of the solution remains. When this dehydration process is completed, a drying process is performed (step S15). In this drying treatment, the temperature is set to about 95 [° C.] and the drying is performed for a sufficient time. Thereby, the pest repellent clothing 1 which concerns on this embodiment which prevents that a pest approaches by performing predetermined pest repellent processing with respect to the clothing fabric 2 can be obtained.

  Therefore, according to the manufacturing method of the pest repellent clothing according to the present embodiment and the pest repellent clothing 1 according to the present embodiment obtained by the manufacturing method, the capsule wall made of the synthetic resin Rs that can be broken at least by friction A large number of microcapsules 3... In which liquid pest repellent 3 d is encapsulated inside 3 s are attached to the surface of the fiber material 2 g... Constituting the clothing fabric 2 and distributed on the surface of the clothing fabric 2. When the pest repellent clothing 1 is attached to the body, the capsule wall 3s of the microcapsule 3 is broken by friction caused by the movement of the body, so that the internal pest repellent 3d is released to the outside and the clothes fabric 2 It adheres to the surface of the fiber material 2g. Since the microcapsules 3 are ruptured randomly according to the position and size of friction, the repellent effect of the pest repellent 3d can be maintained for a long period of time. Moreover, every time the microcapsules 3 are broken, a new liquid pest repellent 3d is released and adheres to the surface of the fiber material 2g in the clothing fabric 2, so that the microcapsules 3 are always sufficient while remaining. The pest repellent garment 1 can be provided with high practicality, such as ensuring repellent performance (initial performance).

  In addition, you may combine other various functions with respect to the pest repellent clothing 1 obtained by the above manufacturing method as needed. For example, by performing a treatment for adding an amphoteric surfactant (glycine betaine or the like), the pest repellent clothing 1 having an excellent water absorption (moisture absorption) function in addition to the pest repellent function can be obtained. Moreover, by performing the process which adds an inorganic compound (quaternary ammonium salt acrylic emulsion), the pest repellent clothing 1 excellent in the antibacterial and deodorant function can be obtained in addition to the repellent function against pests. Of course, both a water absorption (moisture absorption) function and an antibacterial / deodorant function can be added.

  Next, the usage method and action (function) of the pest repellent clothing 1 according to the present embodiment will be described with reference to FIGS.

  4 and 5 show a specific use state of the pest repellent clothing 1. FIG. 4 shows an example in which the pest repellent garment 1 is applied to a garment 1a having a rain-gown shape having a top 1ac having a hat 1ah and a trouser 1ap. The illustrated garment 1a is a woven fabric 2 in which a fiber yarn of cotton 62 [%] and polyester 38 [%] is used to make a mesh woven having high air permeability. FIG. 4 shows a state where the user H wears the clothes 1a and is caring for the tree (shrub) Pa.

  In this state, if the user H moves his / her body, the microcapsules 3... In the clothes 1a are broken by friction, and the insect pest repellent 3d is removed from the broken capsule wall 3s as shown in FIG. The pest repellent 3d released to the outside adheres to the surface of the fiber material 2g. In FIG. 3B, reference numeral 3sc indicates a broken portion in the capsule wall 3s. The pest repellent 3d adhering to the fiber material 2g generates an odor E that repels pests such as mosquitoes and exhibits the function of preventing the pests such as mosquitoes from approaching.

  At this time, as described above, the breakage of each microcapsule 3 is randomly performed according to the generation position and size of friction, and therefore, the repellent effect of the pest repellent 3d is maintained for a long period of time. Can do. Further, each time the microcapsules 3 break, a new liquid pest repellent 3d is released and adheres to the surface of the fiber material 2g in the clothing fabric 2, so that the microcapsules 3 are always sufficient while remaining. Repellent performance (initial performance) can be secured.

  In the case of the illustrated garment 1a, as a result of the experiment, a repellent effect of 94% was obtained in the initial state. The repellent effect of 94% is that if user H wears clothes 1a and stays in a place where mosquitoes are generated for a certain period of time, out of 100 [times] mosquitoes approached 6 [ Times]. On the other hand, as a result of performing normal washing 10 [times] after this, it was confirmed that the repellent effect of 72 [%] was maintained.

  By the way, even if it is such a pest repellent clothing 1 which concerns on this embodiment, it is inevitable that a repellent effect falls gradually by using. In this case, when the solution containing the microcapsules 3 generated by the same generation principle is contained in a spray can, and the repellent effect of the pest repellent clothing 1 is reduced, the microcapsules 3 are sprayed by a spray method using the spray can. It is also possible to add the microcapsules 3 to the pest repellent clothing 1 by spraying on the pest repellent clothing 1.

  FIG. 5 shows a case where the pest repellent clothing 1 is applied to an arm cover 1ba and a foot cover 1bf. FIG. 5 shows a state in which the user H wears the arm cover 1ba in his hand, wears the foot cover 1bf in his / her foot, and cares for the flower Pb by gardening or the like.
