DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bulletproof and antiblade jacket having both a bulletproof performance and a bladeproof performance.

[0002]

2. Description of the Related Art Heretofore, there has been known a bulletproof garment having a bulletproof function for protecting oneself from a bullet fired from a firearm. On the other hand, for example, resin-made blade-proof garments having a blade-proof function of protecting themselves from ice picks and blades (hereinafter, referred to as "blades and the like") are also known (there is no bullet-proof function). However, there has been no bulletproof and anti-blade garment which has these two functions, is lightweight, and is excellent in wearing feeling.

[0003]

Among these prior arts, the conventional bulletproof garments have the disadvantage that they are generally heavy.
In addition, conventional resin blade garments have poor blade protection, are heavy, are uncomfortable and uncomfortable when worn, and generate noise when worn and active, and lack quietness. There was a problem. Even if these conventional bulletproof garments and blade proof garments are simply combined, it is not possible to provide a product that has both high bulletproof performance and high blade proof performance, and is lightweight and excellent in wearing feeling. In addition, secondary disasters, such as when the bobbin is stabbed by a jump or a blade, cannot be effectively prevented.

[0004] Therefore, the present invention provides a bulletproof and anti-blade garment which has both high bulletproof performance and high anti-blade performance, is lightweight, has excellent wearing feeling and quietness, and can effectively prevent a secondary disaster. With the goal.

[0005]

SUMMARY OF THE INVENTION A bulletproof and anti-blade garment according to the present invention which has solved the above-mentioned problems has a high breaking strength of not less than 20 g / d, a breaking elongation of not more than 6% and an initial elastic modulus of not less than 600 g / d. the strength and high modulus fiber having a multilayer structure using at least a portion thereof, and the metal member is attached to an arbitrary position in the thickness direction at the lamination structure, the fabric
However, the opened fiber is turned to 0 ° / 90 ° so as to be orthogonal.
Laminate at least two layers, thermoplastic elastomer resin
Is impregnated and fixed .

In the present invention, a fabric using high-strength high-modulus fibers is provided. The reason why the breaking strength of the high-strength high-modulus fiber is 20 g / d or more and the breaking elongation is 6% or less is to consume a large amount of energy when the fiber breaks. That is, when a bullet is received, the energy of the bullet is offset by the energy at which the fiber is cut. If the breaking strength is less than 20 g / d and the breaking elongation is more than 6%, the energy of the bullet cannot be sufficiently absorbed. The high-strength high-modulus fibers used in the present invention include, for example, wholly aromatic polyamide fibers, polyparaphenylene benzobisoxazole fibers (PBO fibers), wholly aromatic polyester fibers, high-strength polyethylene fibers, and high-strength polyethylene fibers. Examples thereof include polyvinyl alcohol fibers, but are not limited thereto.

Also, when a bullet is received, if the high-strength high-modulus fiber has a high initial modulus, the high-strength high-modulus fiber is very difficult to stretch, so that the energy of the bullet is instantaneously transmitted to a wide area range. be able to. Therefore, in the present invention, fibers having an initial modulus of 600 g / d or more are used as high-strength high-modulus fibers. Thereby, the energy of the bullet can be received by more fibers. If the initial elastic modulus is less than 600 g / d, the efficiency of instantaneously transmitting the energy of the bullet over a wide range is reduced.

[0008] In addition, since the metal member is attached to the cloth, it is possible to exhibit high blade-proof performance in addition to high bullet-proof performance. When attaching the metal member to the cloth, an adhesive or an adhesive can be used.

Further, the cloth used in the bulletproof and blade-proof robe
Is such that at least two layers of opened fibers are laminated at 0 ° / 90 ° so as to be orthogonal to each other, and impregnated with a thermoplastic elastomer resin to be fixed. By adopting such a structure, the elastic modulus of the fabric is increased, and as a result, the energy of the bullet can be instantaneously and efficiently transmitted to a wide area.

Here, it is preferable that the metal member is attached with an adhesive. The adhesive shows semi-permanent viscoelasticity even after pasting, so when repeatedly wearing bulletproof and anti-blade clothing, metal members are less likely to peel than when glued with an adhesive, and in that sense it is durable Will increase.

Preferably, the pressure-sensitive adhesive is a natural rubber latex-based pressure-sensitive adhesive. The natural rubber latex-based pressure-sensitive adhesive has a property of hardening even at a low temperature.
Therefore, by using a natural rubber latex-based pressure-sensitive adhesive as a pressure-sensitive adhesive, high durability performance can be exhibited even when the bulletproof and anti-blade garment is used in, for example, a cold region.

It is desirable that the high-strength high-modulus fiber is an ultrahigh molecular weight polyethylene multifilament having a weight average molecular weight of 500,000 or more, preferably 1,000,000, more preferably 2,000,000 or more. As described above, by using an ultrahigh molecular weight polyethylene multifilament having a weight average molecular weight of 500,000 or more, a fiber having higher strength and higher elastic modulus can be obtained. Thereby, high bulletproof performance can be provided.

Further, it is desirable that the high-strength high-modulus fiber is a multifilament having a single yarn fineness of 12 d or less. When the single yarn fineness is 12d or more, it is difficult to achieve high strength and high elastic modulus of the fiber.
It is necessary to be 2d or less, preferably 6d or less. Further, in the fabric configuration in which the opened fibers are laminated at 0 ° / 90 °, it is more advantageous that the end yarn fibers be 12d or less in order to increase the volume ratio of the fibers.

[0014] Further, it is preferable that at least a part of the high-strength high-modulus fibers used in the fabric constituting the laminate is laminated so that the weft fiber axis is in an arbitrary direction. desirable. As described above, the anisotropy can be eliminated by adopting a mode in which the warp fiber axes are laminated so as to be in an arbitrary direction. Therefore, the energy of the bullet can be distributed over a wide range and evenly.

On the other hand, it is preferable that the metal member has a mode in which a plurality of small pieces are independently attached without any gap. As described above, by adopting a mode in which a plurality of small pieces are independently attached without gaps as a metal member,
Flexibility as a bulletproof and anti-blade garment can be exhibited, so that a feeling of wearing can be improved.

It is preferable that the plurality of small pieces are staggered in the laminating direction. in this way,
By arranging a plurality of small pieces in a staggered manner in the stacking direction, the surface portions of the small pieces in the other layers overlap the gaps between the small pieces in the stacking direction, so that the blade-proof performance can be exerted uniformly in the surface direction. .

Further, at least a part of the plurality of small pieces is desirably a turtle-shaped thin plate. As described above, since the small piece is a tortoiseshell-shaped thin plate, the flexibility as the bulletproof and anti-blade garment is further improved, and the wearing feeling can be further improved. At this time, in addition to the mode in which all of the plurality of small pieces are formed as a turtle-shaped thin plate, for example, a turtle-shaped thin plate and a small piece of another shape may be combined, or a small piece having a shape in which a part of the turtle-shaped portion is cut at an end portion. Needless to say, it is also possible to adopt a mode such as using

Further, the metal member has a density of 5 g /
cm ³ or less, and its thickness is desirably 3 mm or less. The density of the metal member is 5 g / cm ³ or less and the thickness is 3
mm or less, it is possible to reduce the weight of the entire bulletproof and anti-blade garment. For this reason, it contributes to improvement of a feeling of wearing.

Further, the metal member has a hardness of 130 Hv.
It is desirable to use the above titanium plate. Hardness is 130H
By using a titanium plate of v or more, higher blade-proof performance can be exhibited.

It is preferable that a cushioning material is provided on the human body side of the laminate. By arranging the cushioning material on the human body side of the laminated body, it is possible to reduce the impact applied to the human body and reduce the trauma upon impact. Here, trauma is when a bullet is shot by a bulletproof test or the like described below,
It refers to the dent length of the simulated human body substance placed on the back side of the sample. In addition, it eliminates discomfort when worn and contributes to reduction of discomfort.

Further, it is desirable that the weight per unit area of the bulletproof / brush-proof portion of the bulletproof / brush-proof garment is 1.3 g / cm ² or less. By making the weight per unit area of the bulletproof and antiblade garment at the bulletproof and antiblade site not more than 1.3 g / cm ² , the bulletproof and antiblade garment can be made lightweight as a whole and worn. It can contribute to improvement of the performance.

Here, the blade-proof performance preferably has a blade-proof performance with a penetration amount of less than 5 mm measured by the present blade-proof test method. In addition, "the present blade-proof test method" referred to in the present invention will be described in Examples described later.

Further, the bulletproof performance is based on the NIJ standard 010
It is desirable to have bulletproof performance at or above 1.03 threat level IIIa. In addition, "NIJ standard"
0101.03 "will also be described in an embodiment described later.

[0024]

Embodiments of the present invention will be specifically described below with reference to the drawings. 1 (a) is a plan view of the bulletproof and anti-blade garment according to the present invention in an unfolded state, FIG. 1 (b) is a front view of the worn state, and FIG. is there.

As shown in FIG. 1 (a), the front part (ballistic-proof and anti-blade portion) 1 of the cover sheet 11 in the bullet-proof and anti-blade garment 1
1A is provided with a bulletproof and blade-proof clothing member 12 indicated by a virtual line. Also, four surface fasteners (female portions) 13, 13, 1 are provided on the surface of the front portion 11A of the cover sheet 11.
3, 13 are sewn. Then, the cover sheet 11
The back surface portion 11B is mesh-processed, and hook-and-loop fasteners (male portions) 15, 15 are attached to ends thereof via a rubber belt 14. When wearing the bulletproof / battery-proof clothing 1, a wearer (not shown)
6 and the hook-and-loop fasteners (male portion) 15 and 15 are connected to the hook-and-loop fasteners (female portion) 13 and 1 as shown in FIG.
Attach to appropriate positions of 3, 13, 13 and wear.

As shown in FIG. 2, the bulletproof and blade-proof clothing member 12 includes a laminate 3 formed by laminating a plurality of high-strength sheets 2, 2,. The high-strength sheet 2 used in the present embodiment is configured such that the opened fibers are orthogonally crossed by 0 °.
/ 90 ° is a sheet formed by laminating a plurality of layers and impregnating and fixing a thermoplastic elastomer resin. As the cloth, a cloth in which high-strength high-modulus fibers are laminated so that the weft fiber axis is arbitrary can be used. The portion of the fabric using the high-strength, high-modulus fibers does not need to be the entire fabric, and may be in a range that can protect at least the bulletproof and blade-proof part of the human body.

On the human body side (lower side in FIG. 2) of the laminate 3, two metal members 4 and 5 are laminated. The laminated body 3 and the metal members 4 and 5 constitute a member 12 for bulletproof and anti-blade clothing.

As shown in FIGS. 2 and 3, a plurality of metal pieces, that is, titanium pieces 4a, 4a,... It is stuck to the high strength sheet 4b1 with an adhesive. Titanium pieces 4a, 4a, ...
Is adhered to the high-strength sheet 4b2 with a natural rubber latex-based adhesive.

The natural rubber latex-based pressure-sensitive adhesive used in the present invention does not harden for a long time and has a property of maintaining the flexibility semipermanently. For example, titanium pieces 4a, 4
When the metal members 4 are formed by attaching a,... to the high-strength sheets 4b1 and 4b2, if an ordinary adhesive is used, the adhesive hardens after being dried. For this reason, the bulletproof and anti-blade garment is attached or detached or moves while being worn, causing fatigue of the bonded portion, and the metal member 4 is easily peeled off, resulting in poor durability. On the other hand, when attaching the titanium pieces 4a, 4a,... To the high-strength sheets 4b1, 4b2, an adhesive,
In particular, when a natural rubber latex-based pressure-sensitive adhesive is used, its flexibility is maintained, so that the metal member 4 can be prevented from peeling. Therefore, when the metal member 4 is stuck with the adhesive, the metal member 4 does not peel off semi-permanently. In particular, when using a natural rubber latex-based adhesive, even when the temperature is low,
Since it does not harden easily, the metal member 4 can be prevented from peeling off even when the bulletproof and anti-blade jacket 1 is used in a cold region or when it is used in a cold season such as winter. As a result, high bulletproof and blade performance can be reliably maintained.

Further, in this embodiment, another metal member 5 is arranged and laminated on the human body side (the lower side in FIG. 2) of the metal member 4. In the metal member 5, as shown in FIG. 3, titanium pieces 5a, 5a,.
Are spread, and their back surfaces are attached to the high-strength sheet 5b1 with a natural rubber latex-based adhesive. The surface side of the titanium pieces 5a, 5a,... Is adhered to the high-strength sheet 5b2 with a natural rubber latex-based adhesive. The metal member 5 is a metal member 4
Similarly to the above, since it is configured to use a natural rubber latex-based adhesive, it has the same durability as the metal member 4.

Then, as shown in FIG. 4, the positions where the titanium pieces 4a, 4a,... (Shown by solid lines) in the metal member 4 are adjacent to each other, and the titanium pieces 5a, 5a,.
The metal members 4 and 5 are arranged so as to be shifted from adjacent positions (shown by broken lines), that is, staggered in the stacking direction. By arranging the metal members 4 and 5 in a staggered manner in the stacking direction in this way, as shown in FIG. 4, the titanium pieces 4a, 4a,.
are located in the gaps between the titanium pieces 5a, 5a,..., and titanium pieces 4a, 4a,. Therefore, even if a blade or the like is inserted into the gap between the titanium pieces 4a, the wearer's body can be reliably protected by hitting the titanium piece 5a.

As described above, the laminated body 3 formed of the fabric using the high-strength and high-modulus fibers is used as a bulletproof and anti-blade garment in which a metal member is attached using an adhesive.
Since it has both high bulletproof performance and bladeproof performance, it has high flexibility and light weight, so that it does not hinder the movement of the wearer. In addition, the use of the adhesive makes it difficult for the metal member to peel off, and also has much better quietness than conventional resin-made blade-proof clothing.

Although the metal members 4 and 5 are laminated in two layers,
One sheet may be used. Further, the shape of the titanium pieces 4a, 4a, ..., 5a, 5a, ... in the metal members 4, 5 is not limited to a square such as a square or a rectangle, but may be an appropriate shape such as a triangle or a hexagon. It is preferable to form a tortoiseshell shape (regular hexagonal shape). Also, the size and the like can be determined as appropriate. Further, in the present embodiment,
Front part 11 of cover sheet 11 in bulletproof and jacket 1
Although the metal members 4 and 5 and the laminate 3 are arranged with only A as the bulletproof and blade-proof part, the bulletproof and blade-proof part can be set at an appropriate position according to the properties required for the bulletproof and blade-proof clothing 1. For example, a cover sheet 11A for the bulletproof and anti-blade jacket 1
These may be arranged on the back surface portion 11B.

In the above embodiment, the metal members 4 and 5 are laminated on the human body side of the laminate 3. However, the present invention is not limited to this mode.
Laminating a metal member on the outside of a high-strength high-modulus fiber body,
Alternatively, it can be laminated on both the human body side and the outside.

On the other hand, in the above-described embodiment, the laminated body 3 is composed of a set of five high-strength sheets 2, but may be laminated in an appropriate number unit such as a set of three sheets or a set of seven sheets. . In the above-described embodiment, the size of the titanium piece is unified in each metal member. However, the size of the titanium piece is not particularly limited, and titanium pieces having different sizes can be used.

Further, in the above-described embodiment, the bulletproof and anti-blade clothing member 12 is provided in the cover sheet 11.
For example, it is also possible to adopt a mode in which a member for bulletproof and blade-proof clothing is attached to clothing. On the other hand, in order to enhance the buffering effect of the bulletproof and anti-blade garment, it is also preferable to arrange a cushioning material made of, for example, foamed polyethylene on the human body side. As a result, wearability is also improved.

[0037]

EXAMPLES Examples of the present invention and comparative examples will be described below. Here, with respect to the bulletproof and anti-blade garments in each of the examples and comparative examples, tests were performed on four items of anti-blade properties, elasticity, wearability, and functionality. Hereinafter, those test methods will be described. Table 1 shows the evaluation criteria for each material.
It is as shown in FIG.

<Blade-proof test> A blade-proof test was performed based on the present blade-proof test method. The present blade-proof performance test will be described with reference to FIG. As shown in FIG. 5A, a non-resistive slider 31 is installed at a height of about 1.5 M from the sample B on the test table 30, and a vertical fixing screw 32 is provided on an upper part thereof. Further, an oil clay 33 serving as a simulated human body is laid under the sample, and the sample B is placed thereon.

A test ice pick 34 shown in FIG. 5B is attached to the vertical fixing screw 32. The test ice pick 34 was adjusted to have a weight of 1.7 kg. The total length of the blade is 147 mm, and the diameter of the root is φ4.4 mm. 62.5 from the tip
mm from the tip to a position 4.5 mm from the tip, the diameter at a position 4.5 mm from the tip is φ
2.0 mm. A larger taper is provided from a position 4.5 mm from the tip to the tip, and the tip is sharp.

The test ice pick 34 was mounted at a height at which the distance from the tip to the sample B was just 1.5 m, and the resistanceless slider 32 was slid in the direction of the arrow shown in FIG. The test ice pick 34 is allowed to fall naturally. The workload at this time is equivalent to about 25J. Then, the length (L in the figure) of the test ice pick 34 penetrating the sample B is measured.

When measuring the penetrating length, the test table 30 is turned over as it is, and as shown in FIG. 5C, the protruding length of the tip of the test ice pick 34 extracted from the oil clay 33 is measured. Measure L. In addition, instead of the test ice pick 34, a test using a blade knife and a survival knife also adjusted so that the work amount was equivalent to 25 J was also performed.

<Elasticity-proof test> The elasticity-proof test was performed based on the test method of the NIJ standard. In this test method, a bulletproof sample (approximately 30 cm square) is brought into close contact with a 15 cm thick oil clay, which is an NIJ designated human simulated substance, the distance from the muzzle to the sample is set to 5 m, and a bullet is fired. As a method of measuring the initial velocity, a measuring instrument is installed at 5 feet and 10 feet, and the velocity of the bullet detected when the bullet passes through the measuring instrument is set as the maximum and minimum values, respectively, and the average value of both is used for the bullet. Speed.

In this NIJ standard, threat level III
In order to be recognized as a or more, the following conditions are required. As a bullet, 44 magnums of 9 x 19 mm, 24 doses
0Gr (grain) semi-wind cutter with initial speed of 42
Six shots are fired at 8 m / s, and it is determined whether or not to penetrate. When all six shots have not penetrated, each trauma (footnote) is measured. The average value is 44m
If it is less than m, bulletproof performance at or above the threat level IIIa in NIJ standard 0101.03 is evaluated.

In the NIJ standard 0101.03, only the measurement when a bullet is fired from the front is used as a reference. However, in this embodiment, the NIJ standard 0101.03 is used.
According to 101.03, a test for firing a bullet from an oblique direction of 30 ° and a test for firing a bullet from an oblique direction of 45 ° were also performed. Table 1 also shows the results.

<Wearability Test> The wearability test was conducted by a sensory test using 20 monitors. As described above, three types of S, M, and L sizes were prepared as bulletproof and gloves, and each monitor was allowed to select and wear a bulletproof glove of the size best suited to the user. And
The evaluation was made based on whether each monitor felt "comfortable". The lightness was also measured. This lightness is
Based on the appearance of one piece of bulletproof and anti-blade garment around the appearance of one M-size bulletproof and anti-blade garment. The total area of the bullet-proof and blade-proof part is 960 cm ² , and the total weight of the members other than the member for the bullet-proof and blade-proof clothing is about 50 g. That is, when calculating the total weight per piece of M size, the weight per unit area in the bulletproof / shutter-proof part is 1.3 g / cm
² , and the total area of the bulletproof and blade-proof part is 960 cm ² , so the total weight of the bulletproof and bulletproof part is about 1250 g. A total weight of about 50 g other than the bulletproof and blade-proof part is added to this, and the total unit is about 1.3 kg, which is extremely light.

<Functional Test> As a functional test, a quietness test and a durability test were performed. The quietness test was performed on each of the 20 monitors who performed the above-mentioned wearing feeling test.
A 0 m run was performed, and each was sensually evaluated whether or not each felt noisy. In the durability test, it was examined whether or not the metal member had peeled off after 100 m of running.

Example 1 As a high-strength high-modulus fiber,
Ultra-high molecular weight polyethylene multifilaments having a breaking strength of 40 g / d, a breaking elongation of 3.5%, an initial elastic modulus of 1500 g / d, a fineness of single yarn of 2 denier, and a weight average molecular weight of 4,000,000 are placed at 0 ° / 90 °, and a thermoplastic elastomer resin was impregnated and fixed to produce a fabric. A natural rubber latex-based pressure-sensitive adhesive was used for this fabric, and the density was 4.5 g / cm ³ , the thickness was 1 mm, and the hardness was 2
A plurality of 00Hv turtle-shaped titanium pieces stuck together without any gap were placed on the front side of the foamed polyethylene sheet, and further, a similar cloth and a titanium plate stuck to this cloth were placed on the back side. At this time, the adjacent points of the titanium pieces forming both titanium plates were staggered so as not to overlap each other to form a bulletproof and anti-blade coat. In addition, the weight per unit area of the bulletproof and antiblade portion of the bulletproof and antiblade clothing is 1.3 g / cm ² . In addition, three sizes of S size, M size, and L size are prepared as bulletproof and anti-blade clothing, and the total weight of one piece of M size is 1.3 kg.
It is. Table 1 shows the evaluation of each of these tests.

<Blade-proofing property> As a result of measurement based on the present blade-proofing test method, when using an ice pick of 2.1 mm, a blade knife of 1.6 mm, and a survival knife of 0.9 mm, Demonstrated good blade protection.

<Elasticity Prevention> As a result of conducting a test based on the NIJ standard test method, none of the six bullets penetrated. The trauma was very small, averaging 15 mm. In addition, all six bullets could be stopped when fired from either the oblique direction of 30 ° or the oblique direction of 45 °. Thus, it was found that the bulletproof performance was extremely high. Further, the aforementioned N
80-86Gr, 5.5 warhead weight according to IJ standard
g, a steel jacket bullet with a diameter of 7.62 mm and a length of 25 mm from Tokarev at an initial velocity of 490 to 510 m / s
A test to fire 6 shots was conducted. As a result, all six shots were impenetrable, and it was also found that good bulletproof performance was exhibited in such a test.

<Wearability> As for the feeling of wear, all the 20 monitors felt that they were good. The total weight was 1.3 kg in M size, and the description of other sizes was omitted, but the weight was generally light.

<Functionality> The result of quietness was that all 20 monitors felt quiet. Regarding the durability, the metal members did not peel off in the bulletproof and blade-proof clothing of any of the monitors.

Example 2 As a metal member, a density of 8 g /
The test was performed under the same conditions as in Example 1 except that SUS steel having a cm ³ , a thickness of 1 mm, and a hardness of 120 Hv was used. As a result, as shown in Table 1, the bulletproof performance was impervious to all six shots, but the average of the trauma was a slightly large value of 22 mm, which was slightly lower than that of Example 1. Also, in terms of the blade prevention performance, the penetration amount was slightly longer, for example, 2.7 mm with an ice pick, and the result was slightly lower than that of Example 1. However, these results are in a range that can sufficiently withstand practical use. In addition, although it became 3.5 kg as a whole,
The quietness and durability were good.

Example 3 A test was performed under the same conditions as in Example 1 except that the fabric configuration was plain weave. As a result, Table 1
As shown in the figure, up to five shots were not penetrated, but penetrated at the sixth shot. Thus, the ballistic performance was reduced, but the same results as in Example 1 could be obtained in all of the blade-proof property, wearability, and functionality.

Example 4 A test was performed under the same conditions as in Example 1 except that an epoxy-based adhesive was used instead of the natural rubber latex-based adhesive in attaching the metal member. As a result, as shown in Table 1, the durability of the functionality was slightly lowered. That is, out of the 20 monitors, several metal members of the two monitors were peeled off. However, other than the above, the blade-proof property, the elasticity-proof property, the wearability, and the function almost equivalent to those of the example 1 were exhibited.

Example 5 A test was performed under the same conditions as in Example 1 except that no cushioning material was provided. As a result, as shown in Table 1, the wearing feeling in wearability was slightly lowered. That is, 5 out of the 20 monitors complained of poor wearing sensation, but none of them felt uncomfortable. On the other hand, there was no opinion that the absence of cushioning material reduced the overall thickness and improved the feeling of wearing.
I went up from a human monitor. Further, since no cushioning material was provided, the trauma slightly increased.

Comparative Example 1 A single fiber fineness of 1 was used as a fiber material.
The test was performed under the same conditions as in Example 1 except that a fiber material having 5 denier, breaking strength of 18 g / d and breaking elongation of 6% and an initial elastic modulus of 180 g / d was used. As a result, as shown in Table 1, the bullet penetrated at the first shot, ending the test. Also, when the gun was fired from any of the oblique direction of 30 ° and the oblique direction of 45 °, the penetration of the bullet could not be prevented, and the test was completed. Thus, the ballistic resistance was very low. Further, the blade-proofing property was slightly lower than that of Example 1.

Comparative Example 2 A conventional bulletproof garment will be described as Comparative Example 2. Comparative Example 2 is an example in which the same material as in Example 1 was used as the fiber material, and a metal material or the like for imparting blade-proof properties was not provided. In Comparative Example 2, there was almost no blade-proofing property, and although the bullet prevented penetration of two bullets,
The test was over, and the test was over. In addition, diagonal 3
If fired from 0 °, 3 bullets, 45 oblique
When fired from the ° direction, although the penetration of four bullets was prevented, the fourth and fifth bullets respectively penetrated, and the test was terminated. Thus, it did not exhibit very high ballistic resistance.

<< Comparative Example 3 >> A conventional blade-proof garment will be described as Comparative Example 3. In Comparative Example 3, a fiber material for imparting anti-elasticity was not particularly provided, and small pieces made of resin were joined by rivets to impart blade-proof properties. In Comparative Example 3, the first bullet penetrated, ending the test. Also, 30 ° diagonally
In either case, the test was terminated because the bullet could not be prevented from penetrating in either direction.
Thus, it hardly exhibited the anti-elasticity. Further, the blade-proofing property was inferior to Example 1. Further, as quietness, 18 out of 20 monitors felt noisy.
