Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for repelling pests of polyester fiber products. More specifically, a polyester fiber product can be provided with a repellent effect of a blood-sucking pest with excellent washing resistance and durability, and can be provided with a simple method without impairing the feel and physical properties of the textile product. The present invention relates to a pest repellent processing method for a polyester fiber product which can be performed. [0002] In recent years, outdoor sports such as camping, fishing, hiking, tennis and the like have become popular, and opportunities to get acquainted with nature have been increasing. In these outdoor activities,
Especially in summer, damage from various pests is increasing. Among the pests, blood-sucking pests such as mosquitoes, flies, gnats, fleas, ticks, lice and the like are not only damaged by physical pain, but also may transmit infectious diseases, so that it is necessary to reduce the damage. Generally, in order to prevent the damage of blood-sucking pests, wear insect-repellent clothes or cover the living environment with insect-repellent textiles, etc., so that the pests are prevented from getting on the human body. Is adopted. Conventionally, in order to impart repellency to textile products, a method of applying a repellent to the textile product (Japanese Patent Laid-Open No. 2-62804, etc.) has been performed. However, when washed, the repellent flows away and the repellent effect is not maintained. Various methods for repelling textile products have been proposed to improve such washing resistance and durability. For example, a method of applying an emulsion of a repellent and a substance capable of forming a film to a fiber to form a film containing the repellent on the surface of the fiber (Japanese Patent Application Laid-Open Nos. 2-264073 and 3-2348).
No. 77, etc.), powdered repellents (2-6670)
No.), those supported on an inorganic carrier (2-47374)
No.) or microencapsulated (2-36 above)
No. 02, No. 2-200602, No. 3-90682)
For example, a method of forming a coating containing these on a fiber surface with a binder, a method of kneading a repellent into fibers, and the like are known, and various methods of penetrating the repellent into fibers have been reported. [0005] However, these conventional pest repellent methods have various problems. For example,
In the method of applying an emulsion of a repellent and a substance capable of forming a film to the fiber to form a film containing the repellent on the surface of the fiber, the feeling of the treated cloth changes and the persistence of the repellent effect is maintained. Difficult to control. The method of forming a coating containing a powdered repellent, an inorganic carrier supported or microencapsulated on the fiber surface using a binder can release the repellent slowly and sustain Although it has excellent properties, the disadvantage that the change in the feeling of the treated cloth cannot be avoided is recognized. In addition, the method of kneading the repellent into the fiber has excellent washing resistance, but particularly when kneading the repellent into a fiber having a high melting point such as polyester,
At the time of melt spinning, the repellent on the yarn surface may volatilize in the air and deteriorate the working environment, and in order to obtain a certain repellent effect, it is necessary to knead a large amount of repellent, and therefore the physical properties of the fiber Disadvantages such as lowering [0006] On the other hand, the method of infiltrating the repellent into the fiber is less likely to change the feeling and physical properties of the fiber, and the repelling effect can be expected to be long-lasting. . For example, a method of penetrating a repellent into a fiber in a swollen state at the time of spinning (JP-A-59-163)
No. 426, JP-A-4-263617, JP-A-5-3115
No. 09) or a method in which the fiber is swollen using a solvent to penetrate the repellent (No. 3-146678) can be expected to have a good repellent effect, but the treatment method is complicated,
Further, a method of treating and heating unstretched fibers (see 1-4)
No. 0622), the repellent was likely to fall off in the post-processing step of the fiber product, and it was difficult to stably maintain the repellent effect. Furthermore, the method of manufacturing a composite fiber from a resin that easily penetrates the repellent and a resin that easily spreads and infiltrates the specific part with the repellent (No. 2-307912) increases the production cost and increases the physical properties of the fiber. There is a problem that versatility is insufficient because it is specified. The present invention has been made in view of the above points, and provides polyester-containing fiber products having excellent washing resistance and durability and a simple method without impairing the feeling and physical properties of the fiber products. The gist of the present invention is to provide a method for repelling pests of polyester fiber products, which can provide a repellent effect for blood-sucking pests. Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above problems, and as a result, when a polyester fiber product is processed by a specific treatment method using a specific repellent, The repellent can be penetrated and diffused from the surface of the polyester fiber product into the interior of the polyester fiber product, and a polyester fiber product having a repellent effect excellent in washing resistance and persistence against blood-sucking pests can be obtained. The present inventors have found that the operation is simple and that the feeling and physical properties of the fiber product do not change, and have completed the present invention. That is, according to the present invention, N, N-diethyl-m-toluamide is added in an amount of 0.5 / 100 g of polyester fiber product.
This is a method for repelling pests of polyester-based fiber products, which is subjected to heat treatment at 150 to 180 ° C. for 0.1 to 10 minutes after application of g to 10 g. The N, N-diethyl-m-toluamide used in the present invention is known as a repellent, and a commercially available product can be used. The polyester fiber products which can impart the repellent effect in the present invention include yarns, knits, woven fabrics and clothing made of polyester fibers, and the polyester fibers include polyester fibers or polyester fibers. Fibers mixed with cotton, wool, and other synthetic fibers are included. Examples of the mixing method include blending and cross weaving, and it is preferable that at least 30% or more of the polyester fiber is contained in order to sufficiently exert the effects of the present invention. Examples of the polyester fiber include polyethylene terephthalate fiber, and fiber obtained by chemically modifying polyethylene terephthalate fiber for the purpose of improving the anti-pill property, improving the dyeing property of the cationic dye, and the like. it can. In the present invention, as a method for applying N, N-diethyl-m-toluamide to a polyester fiber product, a solution of N, N-diethyl-m-toluamide is prepared, and this solution is used as a polyester fiber product. Or by immersing a polyester fiber product in a solution, squeezing the solution to adhere, and then drying. Examples of the solution of N, N-diethyl-m-toluamide include an aqueous solution dissolved or dispersed and emulsified in water, and a solution dissolved in a solvent such as alcohol, benzene, xylene, and toluene. It is preferable to use The concentration of N, N-diethyl-m-toluamide in the solution is 0.1-3.
0% by weight is preferable, and the amount of N, N-diethyl-m-toluamide applied to the polyester-based fiber product is such that N, N-diethyl-m-toluamide is effectively converted to polyester-based fiber when a subsequent heat treatment is performed. 0.5% per 100 g of polyester fiber product so as to be fixed to the fiber product
-10 g are preferred. 100g polyester fiber product
If the amount of N, N-diethyl-m-toluamide given per unit is less than 0.5 g, the repellency will be insufficiently permanent when heated, and if it exceeds 10 g, the degree of improvement of the repellent effect with respect to the added amount will be reduced. Low cost, not economical, strength, elongation,
It is not preferable because the physical properties of the fiber such as Young's modulus and the like are lowered, and in the case of a dyed product, the dyeing fastness tends to be lowered. The addition amount is more preferably in the range of 0.8 to 5.0 g. As the aqueous solution of N, N-diethyl-m-toluamide, a lower alcohol and / or lower alcohol is used in order to enhance the stability and wettability of the solution and to make it easier to uniformly adhere to the surface of the fibers constituting the polyester fiber product. It is preferable that a nonionic surfactant is used in combination. As the lower alcohol which can be used here, methanol, ethanol, propanol, butanol and the like can be mentioned, and isopropanol is preferable. The amount of lower alcohol used is preferably less than 5% by weight. Examples of the nonionic surfactant which can be used for preparing an aqueous solution of N, N-diethyl-m-toluamide include polyoxyethylene alkyl phenyl ether, polyoxyethylene alkyl ether, polyoxyethylene higher fatty acid ester, and polyoxyethylene higher fatty acid ester. Oxyethylene sorbitan alkylate, polyoxyethylene alkylamine and the like can be mentioned, and polyoxyethylene alkyl ether is preferable. Preferably, the amount of nonionic surfactant used is less than 2% by weight. [0015] The drying after the application of N, N-diethyl-m-toluamide to the polyester fiber product can remove water and / or solvent of N, N-diethyl-m-toluamide used for coating. For example, a polyester fiber product coated with N, N-diethyl-m-toluamide may be heated to 60 to 130 ° C. under normal pressure in an air bath.
For about 30 seconds to about 10 minutes, and an ordinary hot flue, tenter, cylinder dryer or the like can be used. Next, after N, N-diethyl-m-toluamide is applied to the polyester fiber product as described above,

Even if the toluamide is run off, N, N-diethyl-m-toluamide is leached from the inside of the fiber, so that the repellent effect can be exhibited and the durability can be exhibited. The method for repelling pests of polyester fiber products of the present invention can be applied to any shape of fiber products such as yarns, knits, woven fabrics and clothing made of polyester fibers. Properties can be imparted. In addition, repellent processed polyester fiber products can be worn as clothing for outdoor clothing, sports clothing, outdoor work clothing, sleeping bags, etc., or interior textile products such as curtains, carpets, tablecloths, etc.
It can be used as a textile product for exteriors such as a tent in a place that covers a living space, thereby preventing pest damage to the human body. Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited thereto without departing from the gist thereof. Example 1 3 g of N, N-diethyl-m-toluamide was dissolved in 6 g of isopropyl alcohol, and polyoxyethylene stearyl ether (the number of moles of ethylene oxide added was 20) was further dissolved.
After adding 1.5 g, the mixture was diluted with water to 100 ml to obtain a clear aqueous solution. This aqueous solution is mixed with 100% regular polyester short fiber plain woven fabric (30 counts 120 / 2.54
cm, weft 30 count / 70 lines / 2.54 cm), and the excess liquid was squeezed with a mangle so that the liquid adhesion rate was 80%. This was dried in an oven at 80 ° C. for 7 minutes and then heat treated at 170 ° C. for 60 seconds. The hardness and thickness of the obtained woven fabric were equivalent to those of the unprocessed cloth, and no change was observed. After washing the processed cloth 10 times under the conditions of the JIS L0217 103 method, a mosquito repellency test was carried out using the unprocessed cloth as a control together with the finished cloth (worked cloth without washing) as follows. Was. Table 1 shows the results. Test method for confirming repellent effect. Test cloth Finished cloth, processed cloth after repeating washing 10 times, unprocessed cloth. Test Method 30 adult female Aedes albopictus (mating finished about 7 days after emergence) were released into a mosquito breeding cage of about 30 × 30 × 30 cm, and 30 ± 2 ° C., humidity 60-
Under a condition of 70%, a cylindrical test cloth was wound on the human arm of the monitor and exposed into the cage for 2 minutes. During this time, the number of mosquitoes that stopped on the test cloth wrapped around the arm (A: the number of mosquitoes that stopped on the processed cloth, B: the number of mosquitoes that stopped on the unprocessed cloth) were counted, and A ×
100 / number of mosquitoes tested = resting rate (%), (BA) ×
Calculated as 100 / B = repellent rate (%). [Table 1] Comparative Example 1 The same 100% regular polyester short-fiber plain woven fabric as used in Example 1 was immersed in 100 ml of an aqueous solution containing 3 g of N, N-diethyl-m-toluamide prepared in the same manner as in Example 1. The excess liquid was squeezed with a mangle to a liquid adhesion rate of 80%, and dried in an oven at 80 ° C. for 7 minutes to obtain a work cloth. A mosquito repellent effect test was performed using the obtained work cloth and the work cloth after repeating the washing for 10 times in the same manner as in Example 1 to obtain a static rate and a repellent rate. Table 1 shows the results. COMPARATIVE EXAMPLE 2 A 100% cotton plain fabric (130 40 counts / 2.40 yarns) scoured and bleached in 100 ml of an aqueous solution containing 3 g of N, N-diethyl-m-toluamide prepared in the same manner as in Example 1. 54
cm, weft 40 count 65 lines / 2.54 cm), squeezing the excess liquid with a mangle, and adjusting the liquid adhesion rate to 80%.
This is dried in an oven at 80 ° C. for 7 minutes, then
Heat treatment was performed at 70 ° C. for 60 seconds. Example 1 was performed using the obtained work cloth and a work cloth repeatedly washed 10 times.
A mosquito repellency test was performed in the same manner as in Example 1 to determine the static rate and the repellent rate. Table 1 shows the results. Comparative Example 3 3 g of 2-hydroxyethyloctyl sulfide was dissolved in 6 g of isopropyl alcohol, and 1.5 g of polyoxyethylene stearyl ether (the number of moles of ethylene oxide added: 20) was added, followed by dilution with water to 100 ml. A clear aqueous solution was obtained. Example 1 using this aqueous solution
The same regular polyester 100% short fiber plain woven fabric was impregnated with a liquid adhesion of 80%, dried in an oven at 80 ° C. for 7 minutes, and then heat-treated at 170 ° C. for 60 seconds. A mosquito repellent efficacy test was performed in the same manner as in Example 1 using the obtained work cloth and the work cloth that was repeatedly washed 10 times, and the static rate and the repellent rate were obtained. Table 1 shows the results. As shown in Table 1, all of the comparative examples had excellent repellency after finishing the processing, but the effect was remarkably reduced and the washing resistance was inferior when the washing was repeated. Sample No. 1 exhibited excellent effects both at the end of processing and after washing, and had good washing resistance. Examples 2 to 4 and Reference Examples 1 to 2 20 g of N, N-diethyl-m-toluamide were mixed with 5.0 g of polyoxyethylene phenyl ether (mol number of ethylene oxide added: 10), and the mixture was heated and stirred at 75 ° C. While adding 75 ml of warm water little by little, an oil-in-water stable emulsion (concentration: 20%) was obtained. A treatment liquid was prepared by adding water in the proportions shown in Table 2 to this emulsion, and the same regular polyester 100% short fiber plain woven fabric as used in the example was immersed in the same manner as in Example 1, and the liquid was adhered. The excess liquid was squeezed with a mangle to a ratio of 80%. Then put it in the oven for 8
It dried at 0 degreeC for 7 minutes, and also heat-processed at 160 degreeC for 2 minutes, and obtained the work cloth used for Examples 2-4. The hardness and thickness of the obtained woven fabric were the same as that of the unprocessed cloth, and no change was observed. In addition, using the processing liquid of the same composition as Example 2 and 4 of Table 2, it is immersed in the same ratio in the same plain textile as above, squeezed to a liquid adhesion rate of 80%, dried, and only the heat treatment step is omitted. The prepared fabric was used for Reference Examples 1 and 2. Next, a blank cloth treated with water under the same conditions and in the same process as above was used as a blank cloth, and the mosquito was treated against mosquitoes in the same manner as in Example 1 using the blank cloth and the processed cloths of Examples and Reference Examples obtained above. A repellency test was performed to determine the static rate and the repellent rate. Table 2 shows the results.
Shown in [Table 2] As shown in Table 2, Examples 2 to 4 exhibited a repellent effect according to the amount applied and excellent washing resistance. On the other hand, in the reference example, the repelling effect at the time of finishing the processing was excellent, but the effect was significantly reduced after washing. This is because in the example, N, N-diethyl-m-toluamide was added to the polyester fiber and subjected to heat treatment. As a result, N, N-diethyl-m-toluamide permeated and diffused into the fiber, and was washed. Even when N, N-diethyl-m-toluamide on the fiber surface was run off, a phenomenon of oozing out from the inside of the fiber occurred. On the other hand, in the reference example, no heat treatment was performed, so that N, N-diethyl-m-toluamide was removed. It is presumed that insufficient permeation and diffusion into the interior of the fiber was caused, and most of N, N-diethyl-m-toluamide was washed away by washing. Examples 5 to 7 and Reference Examples 3 to 6 N, N-diethyl-m-toluamide (5 g) was dissolved in isopropyl alcohol (10 g), and polyoxyethylene cetyl stearyl ether (ethylene oxide added mole number 2
0) After adding 2.0 g, the mixture was diluted to 100 ml with water to obtain a clear aqueous solution. This aqueous solution was immersed in a 100% staple dyeable polyester short fiber knitted fabric (32th milling knitting) in the same manner as in Example 1 to a liquid adhesion rate of 80%, and dried in an oven at 80 ° C. for 7 minutes. After drying, heat treatment was performed under various conditions shown in Table 3 to obtain a work cloth. A repellent test for mosquitoes was performed on the obtained processed cloth in the same manner as in Example 1 to determine a static rate and a repellent rate. Table 3 shows the results. [Table 3] As shown in Table 3, in the range of the processing conditions of Examples 5 to 7, a good repellent effect was obtained both after finishing the processing and after washing 10 times without changing the physical properties of the fibers. No. 4 has a good repellent effect after finishing, but the effect after washing decreases. Reference Examples 5 and 6 have low effects both after finishing and after washing. Further, Reference Example 6 shows shrinkage and hardening of fibers. Was. Thus, in the heat treatment after the application of N, N-diethyl-m-toluamide, if the treatment temperature is low, most of the effect is lost after washing due to insufficient penetration and diffusion of the repellent into the fiber (reference). Examples 3 and 4), if the treatment temperature is too high, the repellent will volatilize more than the part that permeates and diffuses into the fiber, and will not exhibit good effects both at the time of finishing and after washing (Reference Examples 5 and 5). 6) Further, if the fiber is further exposed to a high temperature for a long time, it is considered that the physical properties of the fiber also change (Reference Example 6). As described above, the pest repellent processing method for a polyester fiber product of the present invention specifies a repellent and a fiber and performs treatment under specific conditions. To the inside of the polyester fiber product from the surface to diffuse into the inside, giving a repellent effect with excellent washing resistance and persistence to blood-sucking pests. I get it. Compared to conventionally known processing methods, it has features such as being a simple processing method and being applicable to any product form.
