Description

One aspect of the present invention relates to pest-proofing fabrics.

For example, as disclosed in Patent Document 1, a fabric with pest control performance is known, which is obtained by soaking the fabric in a solution containing a pest behavior distracting agent and retaining the pest behavior distracting agent. However, even if the fabric is immersed in the solution containing the insect pest behavior distracting agent of Patent Document 1, if the fabric cannot sufficiently retain the pest behavior confusing agent, sufficient pest control performance may not be exhibited. I understand.

International Publication No. 2005/018329

As a means to solve such problems, Patent Document 1 describes that a resin binder is applied to the entire surface of the fabric to retain the pest behavior confusion inducer, but this time, it is not enough to be used as clothing. A new problem arises in that there are cases where the texture is not provided. Therefore, as a result of intensive studies, the inventors found that by providing a resin composition containing a thermoplastic resin and a pest behavioral confusion inducer in the form of dots on the surface of the fabric, it was possible to create a garment that has insect repellent properties and can be used as clothing. It has been found that a sufficient texture can be obtained. However, the inventors discovered a new problem in that when the fabric produced in this way is washed, the pest control performance is significantly reduced and cannot be sustained.

Accordingly, an object of one aspect of the present invention is to provide a pest-proofing fabric that has excellent pest-proofing performance, maintains its pest-proofing performance even after washing, and has a feel sufficient for clothing.

[1] The pest-proofing fabric according to one aspect of the present invention includes a fabric as a base material, and dots attached to at least one surface of the fabric and containing a thermoplastic resin and a pest behavior confusion inducer. a dot-shaped resin composition part, and the area occupation rate of the dot-shaped resin composition part with respect to the fabric is in the range of 2.4% to 65.0%, and the pest behavior disturbance per dot-shaped resin composition part is The initial content C1 of the inducer is in the range of 0.005 μg to 0.70 μg, and the initial content C1 and the content C2 of the pest behavior confusion inducer per dot-shaped resin composition part after washing are calculated by the following formula. (1) is satisfied.
0.28≦(C1-C2)/C2≦2.12...(1)

The inventors of the present application believe that the cause of the significant decrease in pest control performance after washing is that the pest behavior distracting agent falls off from the thermoplastic resin that forms the dot-shaped resin composition portion during washing, and the surface of the dot-shaped resin composition portion It was found that this is due to a decrease in the amount of insect pest behavior inducing agents present in the insects. Therefore, the inventors of the present application have conducted extensive studies, and found that even if the pest behavior confusion inducer falls off from the thermoplastic resin and the pest control performance temporarily decreases, the insect behavior confusion inducer contained in the thermoplastic resin By controlling the ease with which bleed-out occurs, the pest behavior distracting agent can be induced to the surface of the dot-shaped resin composition portion from which the insect pest behavior distracting agent has fallen off, and the initial pest control performance can be restored; In other words, it has been found that the pest control performance can be maintained even after washing.

As a specific configuration for controlling the ease of occurrence of bleed-out, in the insect-proof fabric according to one aspect of the present invention, the relationship between the initial content C1 and the content after washing C2 is 0.28≦(C1 -C2)/C2≦2.12, the amount of insect pest behavior inducing agent per dot-shaped resin composition part is adjusted. Here, C1 indicates the initial content of the pest behavioral confusion inducer per dot-shaped resin composition part. C2 indicates the content of the pest behavioral confusion inducer per dot-shaped resin composition part after washing. Here, (C1-C2) can be said to indicate the space (size) of the insect pest behavior confusion inducer that has fallen off from the dot-shaped resin composition part due to washing. In other words, (C1-C2) can be said to indicate the size of the space in which the insect pest behavior confusion inducer remaining in the dot-shaped resin composition portion can move. In addition, the value obtained by dividing such (C1-C2) by C2 is the mobility of the pest behavior confusing agent remaining in the dot-shaped resin composition part per piece, in other words, the bleed-out of the pest behavior distracting agent. It can be said that this indicates the ease with which this occurs (the ease with which the dot-shaped resin composition moves to the surface).

Here, when the value of (C1-C2) is relatively high, it indicates that there is a large space in the dot-shaped resin composition portion in which the pest behavior distracting agent can move. The inventors of the present application have found that when the value of (C1-C2)/C2 is too high, although there is a large space in which the pest behavior confusing agent can move in the dot-shaped resin composition part, the amount of the pest behavior distracting agent remaining. It has been found that due to the lack of insect pest behavior confusion inducer, it is not possible to exist in an appropriate amount in the above-mentioned space, and the insect pest control performance is not sufficiently exhibited. On the other hand, when the value of (C1-C2) is relatively low, it indicates that there is a small space in the dot-shaped resin composition portion in which the pest behavior distracting agent can move. The inventors of the present application have found that when the value of (C1-C2)/C2 is too low, the space in which the pest behavior distractor should move in the dot-shaped resin composition portion is small, but the resins present in the space are strong with each other. It has been found that the insect pest control performance is not fully demonstrated in this case as well, because the insect pest behavior disorder inducer is not sufficiently transferred.

In the insect-proof fabric having this configuration, the value of (C1-C2)/C2 is appropriately adjusted as shown in the above formula (1), so that the insect behavior confusion-inducing agent in the dot-shaped resin composition portion is Mobility is ensured, and bleed-out of the insect pest behavior inducing agent can occur appropriately. As a result, the insect pest behavior disorder-inducing agent can be transferred to the surface of the dot-shaped resin composition portion, so that the pest prevention performance is excellent and the pest prevention performance can be maintained even after washing. Further, in the pest-proofing fabric according to one aspect of the present invention, the area occupation rate of the dot-shaped resin composition portion to the fabric is in the range of 2.4% to 65.0%, so that the fabric has sufficient texture as clothing. can be provided.

[2] In the pest-proofing fabric described in [1] above, the fabric as a base material has a mass per unit area in the range of 30 g/m ² to 150 g/m ² and a JIS L 1092 water repellency test. It may have at least one of 3rd to 5th grade water repellency. According to the inventors' studies, especially when the fabric is a thin fabric of about 30 g/m ² to 150 g/m ² or has water repellency of about grade 3 to grade 5 in the JIS L 1092 water repellency test. In the case of a water-repellent fabric, even if the fabric is immersed in a solution containing the pest behavior confusion inducer of Patent Document 1, the pest behavior confusion inducer cannot be sufficiently retained, and sufficient pest control performance cannot be achieved. I found out that it doesn't show up. As a result of intensive studies, the inventors found that even if the fabric used as a base material is a relatively thin fabric or a water-repellent fabric, thermoplastic resins and insect pest behavior confusion. It has been found that by forming the resin composition portion containing the inducer into a dot shape, it is possible to make the fabric hold the insect pest behavior confusion inducer. With this configuration, even if the fabric used as the base material is a relatively thin fabric or a water-repellent fabric, it has excellent pest control performance and is resistant to pests when washed. It has long-lasting performance and has a sufficient texture as clothing.

[3] In the pest-controlling fabric according to [1] or [2] above, the initial content I of the insect pest behavior-disrupting agent is 1.5% by mass to 30% by mass based on the total amount of the dot-shaped resin composition. The dot-shaped resin composition is in the range of 0% by mass, and the residual rate R of the pest behavior confusion inducer after washing is in the range of 10.0% to 99.0%, and the dot-shaped resin composition is in the dot diameter of the dot-shaped resin composition part. The ratio of the height of the material part (height of the dot-like resin composition part/dot diameter of the dot-like resin composition part) r is in the range of 0.050 to 1.000, the initial content I, after washing. The residual rate R and the ratio r may satisfy the following formula (2).
1.24≦1000×(I/100) ² ×(R/100)/r ^1/6 ≦13.48...(2)

Here, when the initial content rate I is high, the more the residual rate R of the pest behavior confusion inducer after washing is relatively low, the more the pest behavior confusion inducer bleeds out appropriately and the surface of the dot-like resin composition part. However, if the residual rate R after washing is too low, bleed-out progresses too much and the insect pest behavior confusion inducer is present from the dot-shaped resin composition part. As a result of extensive studies, the inventors of the present application found that the agent no longer exists. On the other hand, when the initial content rate I is low and the residual rate R after washing is relatively high, the pest behavior confusion inducer bleeds out appropriately and the pest behavior confusion inducer is present on the dot surface. Although this tends to be the case, if the residual rate R after washing is too high, bleed-out will hardly progress and the insect behavior confusion inducer will be unevenly distributed inside the dot-shaped resin composition part. As a result of intensive studies, the inventors of the present application discovered this. In addition, the lower the value of the ratio r of the height of the dot-like resin composition part to the dot diameter of the dot-like resin composition part (the closer to the flat shape), the easier the bleed-out tends to progress. As a result of intensive study, the inventors of the present application discovered this. The above formula (2) reflects the trends of the initial content rate I, the residual rate R after washing, and the height ratio r, and calculates the balance of the bleed-out of the pest behavior confusion inducer from the dot-shaped resin composition part. It can be said that this is what is shown.

In the insect-proof fabric with this configuration, the value of 1000 x (I/100) ² x (R/100)/r ^1/6 is appropriately adjusted as shown in equation (2) above, so the dot The mobility of the pest behavior distracting agent in the resin composition part is ensured, and bleed-out of the pest behavior distracting agent can occur appropriately.

[4] In the pest-proofing fabric according to [3] above, the initial content I is in the range of 8.0% by mass to 16.0% by mass, and the residual rate R after washing is 20.0% to 80.0%, and the initial content I, the residual rate R after washing, and the ratio r may satisfy the following formula (3).
9.15≦1000×(I/100) ² ×(R/100)/r ^1/6 ≦11.98...(3)

In the insect-proof fabric with this configuration, the value of 1000 x (I/100) ² x (R/100)/r ^1/6 is appropriately adjusted as shown in equation (3) above, so the dot The mobility of the pest behavior distracting agent in the resin composition part is ensured, bleed-out of the pest behavior distracting agent can occur appropriately, and pest control performance is maintained at a higher level even when washed. be able to.

[5] In the pest-proofing fabric according to [3] or [4] above, the ratio r is in the range of 0.060 to 0.300, and the initial content I, the residual rate R after washing, and the ratio r are , may satisfy the following formula (4).
9.34≦1000×(I/100) ² ×(R/100)/r ^1/6 ≦11.79...(4)

In the insect-proof fabric with this configuration, the value of 1000 x (I/100) ² x (R/100)/r ^1/6 is appropriately adjusted as shown in equation (4) above, so the dot The mobility of the pest behavior distracting agent in the resin composition part is ensured, bleed-out of the pest behavior distracting agent can occur appropriately, and pest control performance is maintained at a higher level even when washed. In addition, the timing at which the pest-proofing fabric exhibits its pest-proofing properties can be brought forward.

[6] In the pest-proofing fabric according to any one of [1] to [5] above, the resin composition portion may further contain an ultraviolet absorber, and the ultraviolet absorber may be a triazole type. With this configuration, the timing at which the pest-proofing fabric exhibits its pest-proofing properties can be brought forward.

According to one aspect of the present invention, it is possible to have excellent pest control performance, maintain the pest prevention performance even after washing, and have a feel sufficient as clothing.

The number of dot-shaped resin composition parts 20 can also be determined by observing the dot-shaped resin composition parts 20 formed in a dot shape from above using a microscope (VHX-600 manufactured by Keyence Corporation) and counting the number. It can be measured by

The ratio of the content rate of the thermoplastic resin to the content rate (initial content rate) of the pest behavior confusing agent R2 (content rate of thermoplastic resin/content rate of the pest behavior distracting agent) is, for example, 0.5 to 5. It is in the range of 0, preferably in the range of 0.8 to 4.0.

When the initial content of the pest behavioral disturbance inducer R2 per dot-shaped resin composition part 20 is defined as C1, the initial content C1 is in the range of 0.005 μg to 0.70 μg. The initial content C1 can be set to 0.03 μg or more, 0.31 μg or more, or 0.35 μg or more from the viewpoint of good initial pest control performance. Further, the initial content C1 can be set to 0.60 μg or less, 0.57 μg or less, or 0.53 μg from the viewpoint of maintaining initial fastness and improving washing durability.

Next, the pest behavior per dot-like resin composition part 20 is determined by dividing the content of the pest behavior confusion inducer R2 by the number of dot-like resin composition parts 20 fixed to the measurement sample before washing. The initial content C1 of the confusion inducer R2 is calculated.

When the content of the insect pest behavior disturbance inducer R2 per dot-shaped resin composition part 20 after washing is defined as C2, the content after washing C2 is in the range of 0.002 μg to 0.60 μg. The content C2 after washing can be 0.02 μg or more, 0.12 μg or more, or 0.17 μg or more from the viewpoint of good pest control performance after washing. Further, the content C2 after washing can be set to 0.40 μg or less, 0.35 μg or less, or 0.30 μg from the viewpoint of achieving both good pest control performance after washing and economical efficiency. From these viewpoints, the content C2 after washing is preferably in the range of 0.02 μg to 0.40 μg, more preferably in the range of 0.12 μg to 0.35 μg, and even more preferably 0.17 μg. ~0.30 μg.

First, the above-mentioned sample for measurement after washing was washed 20 times under the C4M conditions described in JIS L 1930 Home Washing Test Methods for Textile Products. After that, the method for obtaining the initial content C1 is the same as the method of obtaining the initial content C1. The content of the insect pest behavior confusion inducer R2 is determined. Next, the pest behavior per dot-like resin composition part 20 is determined by dividing the content of the pest behavior confusion inducer R2 by the number of dot-like resin composition parts 20 fixed to the sample for measurement after washing. The content C2 of the confusion-inducing agent R2 after washing is calculated.

In the pest-proofing fabric 1 of this embodiment, one dot-shaped resin composition part 20 is designed to induce insect pest behavior so that the initial content C1 and the content after washing, C2, determined as described above, satisfy the following formula (1). Contains confusion inducer R2.

A method for obtaining the post-washing residual rate R of the insect pest behavior confusion inducer R2 will be explained. First, the above-mentioned sample for measurement after washing was washed 20 times under the C4M conditions described in JIS L 1930 Home Washing Test Methods for Textile Products. Thereafter, in the same manner as the method for obtaining the content before washing, the pest behavior confusion inducer R2 was extracted from the dot-shaped resin composition part 20 fixed on the measurement sample after washing 20 times, and extracted by gas chromatography. The content of the insect pest behavior confusion inducer R2 (content after washing) is determined. Next, the post-washing residual rate R is calculated by dividing the post-washing content by the pre-washing content.

For example, by increasing the ratio of the content rate of the thermoplastic resin R1 (the content rate of the thermoplastic resin R1/the content rate of the pest behavior confusing agent R2) to the content rate (initial content rate I) of the pest behavior confusing agent R2, , the residual rate R after washing can be increased.

The ratio r can be set to 0.050 or more, 0.060 or more, or 0.070 from the viewpoint of maintaining the residual amount of the insect pest behavior confusion inducing agent R2 after washing. In addition, the ratio r may be set to 1.000 or less, 0.300 or less, or 0.100 or less from the viewpoint of ease of movement of the pest behavioral confusion inducer R2 to the surface of the dot-shaped resin composition portion 20. can.

That is, a PET film cut to 12 cm x 15 cm was set inside the tube, and a specimen of the same size (from Examples 1 to 11 above, Comparative Examples 1 to 4 above, and Reference Examples 1 to 2 above) was placed inside the PET film. A pre-washing measurement sample and a post-washing measurement sample of pest-proof fabric 1) were set with the side to which the pest behavior confusion inducer R2 was attached facing inside. Then, adult Aedes albopictus (female) test insects were introduced into the tube in which the PET film and specimen were set. Thereafter, the number of test insects knocked down was counted every 5 minutes from 0 to 30 minutes and every 10 minutes from 30 minutes to 60 minutes.

For the pre-washing measurement samples of the insect-proof fabric 1 of each of the above Examples 1 to 11, the above Comparative Examples 1 to 4, and the above Reference Examples 1 to 2, every 5 minutes from 0 to 30 minutes, and from 30 minutes to The number of test insects knocked down is counted every 10 minutes for 60 minutes, and the average value of these counted numbers is defined as the "average number of knocked down before washing". The "average number of knockdowns before washing" indicates that the higher the number, the higher the pest control performance. For the samples for measurement after washing of the insect-proof fabric 1 of each of the above Examples 1 to 11, the above Comparative Examples 1 to 4, and the above Reference Examples 1 to 2, each count was calculated every 5 minutes from 0 to 30 minutes. The average number is defined as the "average number of knockdowns after washing at 30 minutes", and the number obtained by averaging each count every 10 minutes between 30 and 60 minutes is defined as "average number of knockdowns after washing at 60 minutes". The "average number of knockdowns after washing at 30 minutes" and the "average number of knockdowns after washing at 60 minutes" indicate that the higher the number, the higher the pest control performance.

In the pest-proofing fabrics 1 of Examples 1 to 11 above, the "average number of knockdowns before washing" was 10. That is, it was found that the pest-proofing fabrics 1 of Examples 1 to 11 exhibited sufficient pest-proofing performance. In the pest-proofing fabrics 1 of Examples 1 to 11 above, the "average number of knockdowns after washing at 30 minutes" ranged from 1.5 to 5.5, indicating that the pest-proofing performance was reduced. Furthermore, in the pest-proofing fabrics 1 of Examples 1 to 11 above, the "average number of knockdowns after washing at 60 minutes" ranged from 9.3 to 10.0, and the "average number of knockdowns after washing at 30 minutes" It was confirmed that there was a significant increase compared to That is, in the pest-proofing fabrics 1 of Examples 1 to 11, although the pest-proofing performance temporarily decreased after washing, it was found that the pest-proofing performance recovered to almost the same level as before washing. As a result, the pest-proofing fabrics 1 of Examples 1 to 11 have excellent pest-proofing performance and even when washed, even if the fabric 10 as a base material is a relatively thin thin fabric. It was confirmed that this was sustained.

In addition, in the pest-proofing fabrics 1 of Examples 1 to 11, whether the ultraviolet absorber is triazole-based or triazine-based, the pest-proofing performance is excellent and the pest-proofing performance remains even after washing. I was able to confirm that it was. In addition, all of the pest-proofing fabrics 1 of Examples 1 to 11 had good texture evaluations. As a result, it was confirmed that the pest-proofing fabrics 1 of Examples 1 to 11 had sufficient texture as clothing.

In Comparative Example 1, the value of "(C1-C2)/C2" was not appropriate. Specifically, the value of "(C1-C2)/C2" was below the lower limit of the above formula (1). As a result, the desired sustainability of pest control performance could not be achieved. As a result, it was confirmed that if the value of "(C1-C2)/C2" was less than the lower limit of the above formula (1), the desired sustainability of pest control performance could not be obtained. In addition, in Comparative Example 1, the value of "1000×(I/100) ² ×(R/100)/r ^1/6 " was also not appropriate. Specifically, the lower limit of "1000×(I/100) ² ×(R/100)/r ^1/6 " did not satisfy the above formula (2).

In Comparative Example 2, the value of "(C1-C2)/C2" was not appropriate. Specifically, the value of "(C1-C2)/C2" exceeded the upper limit of the above formula (1). As a result, the desired sustainability of pest control performance could not be achieved. As a result, it was confirmed that when the value of "(C1-C2)/C2" exceeds the upper limit of the above formula (1), the desired sustainability of pest control performance cannot be obtained. In addition, in Comparative Example 2, the value of "1000×(I/100) ² ×(R/100)/r ^1/6 " was also not appropriate. Specifically, the upper limit value of "1000×(I/100) ² ×(R/100)/r ^1/6 " did not satisfy the above formula (2).

In Comparative Example 3, the area occupancy of the dot-like resin composition portions 20 with respect to the fabric 10 did not satisfy the range of 2.4% to 65.0%. Specifically, the area occupancy rate was less than 2.4%. As a result, the desired sustainability of pest control performance could not be achieved. As a result, if the value of the "area occupancy rate of the dot-shaped resin composition portion 20" is less than the lower limit of the range of 2.4% to 65.0%, even if the above formula (1) is satisfied, It was confirmed that the desired sustainability of pest control performance could not be obtained.
