DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a uniform cloth having a blade-proof material attached to a lining, which is flexible and has excellent mobility, and has anti-blade protection with emphasis on wearability.

[0002]

2. Description of the Related Art As conventional anti-blade protective clothing, the whole body is a single metal plate, a plurality of laminated plates or a high-strength laminated woven fabric integrally formed by resin impregnation as disclosed in JP-A-63-152232. There have been proposed blade-proof vests worn in uniforms and inside shirts, such as products having a structure in which small pieces of metal plates are combined as disclosed in JP-A-1-46594. Also, as a thing to wear in a uniform,
JP-A-11-183, a jacket-shaped bulletproof garment in which fabrics woven by para-type aramid fiber spinning as in JP-A-8-334296 are laminated and stored in an inner pocket between a surface material and a lining.
As disclosed in JP-A-993, there has been proposed an outerwear with a protective function in which a protective plate for blades or bullets is detachably provided on the back side of the outer body.

[0003]

However, in the former two known examples, no consideration is given to the wearability, and they are very hard and have poor mobility. In addition, there is a drawback that the laminated plate hits and makes a sound every time the exercise is performed.
For this reason, police officers hated wearing them and could not wear them at all times, putting them in danger. In the third known example, although 100% of para-aramid fiber is not flexible, it cannot be said that the blade-proofing performance is sufficient although it is flexible and excellent in wearability and has anti-elasticity. The fourth known example is one in which one or more hard protective plates such as a metal plate are disposed on an outerwear, which is poor in wearability and heavy, and can be used only partially such as the chest. Was. That is,
In the prior art, there is no one that can simultaneously satisfy the wearability and the blade-proof property.

[0004] In view of the drawbacks of the prior art, the present invention provides
It is an object of the present invention to provide a uniform having excellent protection against blades, which simultaneously satisfies three characteristics of protection, especially blade protection against slash, and flexibility, that is, wearability.

[0005]

The present invention employs the following means in order to solve the above problems. That is, the uniform of the present invention is a uniform, in which a blade-proof material is incorporated, as the blade-proof material, a cloth-like material, a net-like material, and a braid in which metal ropes composed of a plurality of metal strands are arranged in the process. At least one sheet-shaped material selected from the shapes is attached to the backing material.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention has intensively studied a uniform having excellent anti-blade protection which simultaneously satisfies the above-mentioned problems, namely, mobility and blade-proofing properties, and also flexibility, that is, three characteristics of wearability. However, it has been found that such a problem can be solved at once by adopting a metal rope sheet material as a blade-proof material.

In the present invention, a metal rope made of a plurality of metal strands is used as such a sheet made of metal rope. As the metal rope, a rope made of stainless steel and carbon steel is preferably used. . Such a rope preferably has a diameter of 0.03 to 0.2
A rope obtained by twisting 0 mm strands, preferably 21 to 49 strands, is used, and more preferably, a rope finished to 0.4 to 1.5 mm in diameter is used. However, the material is not limited to this. Further, as the number of constituent wires, a single twisted form of seven wires is used, and this is preferably 3 to
7 bundled strands, more preferably 7 strands
Forty-nine bundles are optimally used. That is, it is preferable that the number of constituent wires is large, since the strands are thin and flexible. Also, the diameter of the metal rope is preferably 0.4 to 1.2 mm
Is optimal. If the diameter of the metal rope is small, the blade resistance is not obtained unless the density is high, and the cost is high. If the diameter is too large, the metal rope becomes coarse and hard, so it is preferably 0.5 to 1.2 mm. Further, in order to prevent scratching when touching the end surface of the metal rope and to prevent unevenness of the cut surface, and to heat-fix a structure such as a fabric, the metal rope is coated with a thermoplastic resin such as a nylon resin. It is desirable to do.

[0008] The sheet-like material of the present invention includes a cloth obtained by laminating such a metal rope to the background and laminating it with a film or a nonwoven fabric, a cloth-like substance obtained by laminating and laminating in one direction and laminating the background, and a metal. Either a rope or a cross woven fabric made of synthetic fibers can be employed. The above-mentioned laminated product is slightly harder but cheaper, and the mixed fabric is slightly more expensive.However, if the warp woven with a metal rope is superimposed on the background, it becomes flexible, so this structure is flexible. Most preferably used.
If weave the plain woven fabric with the metal rope alone, it becomes slightly harder.However, if the metal rope weave density is coarse and the weave structure is made of satin fabric or oblique fabric, the number of intersections between the metal ropes can be reduced. It can be provided at low cost without sacrificing flexibility. Specifically, 1/3 twill for oblique text,
For satin, a five-sheet satin structure is preferably employed.

The number of the metal rope and the synthetic fiber is as follows:
Preferably, the ratio is in the range of 1: 1 to 1: 4, and especially when the metal rope is interwoven, the higher the synthetic fiber ratio is, the more flexible it is. As the synthetic fiber, high-strength nylon, polyester, para-polyamide fiber, high-strength polyethylene and the like can be used, but a para-polyamide fiber which is strong and has high heat resistance is most preferably used. That is, the yarn strength is 5.3c.
Fibers of N / dtex or more are preferably used from the viewpoint of the blade-proof property. The higher the density of such a high-strength woven fabric, the higher the cut resistance becomes, and it is preferable because a large blade-proof effect can be obtained especially for an ice pick.

[0010] Next, as the sheet-like material, in addition to a cloth-like material such as a woven fabric, a net-like material or a braided material is preferably used. That is, these sheet-like materials are characterized in that since the yarns are obliquely interlaced, they have excellent bending flexibility. The intersection angle between the longitude and the latitude is preferably 30 to 150.
By setting the range of degrees, there is a feature that the longitudinal direction and the lateral direction of the sheet-like material can be strengthened. Such an intersection angle is more preferably 30 to 70 degrees and 110 to 1.
The two positions are at 50 degrees, but may be orthogonal.

[0011] Next, as a net-like material, Russell knitting,
Knotless nets are preferably employed, and in all cases, knitting with synthetic fibers is preferred. That is, in Russell knitting, a metal rope is inserted into a core yarn, a synthetic fiber is made into a chain knitting yarn, and the mesh size is 5 to 20 mm.
Is preferably employed. In addition, the knotless net is obtained by twisting two filaments of a synthetic fiber and a metal rope to obtain a twist-balanced net. However, metal rope 1
Even at 00%, a stable net can be obtained by adjusting the balance between the number of twists and the number of twists. These net-like objects have a flexible structure in which metal ropes are crossed diagonally.

[0012] The same applies to the braided material. The braid has a structure in which metal ropes cross in an oblique direction, and a flat braided braid or a round braided braid can be developed and used. There are benefits to be gained.

In such uniforms, the heart is the most important protective part, and a material that can protect against piercing is required. For this reason, attach a bag to the back of the breast pocket,
A method of inserting a metal plate is preferably employed. In addition, it is preferable to be detachable because there is an advantage that the work can be removed and performed in a safe indoor operation or the like.

The metal plate is made of duralumin, an aluminum alloy,
Stainless steel, titanium alloy and the like are preferably used, and among them, duralumin having a thickness of 1 to 1.5 mm which is light and inexpensive is most preferably used.

Next, a method of attaching the sheet to a uniform will be described. First, the sheet-like material is cut into the shape of the front and back of the left and right sides of the uniform, and when the metal rope appears on the front or back side, it feels strange and uncomfortable,
The sheet is wrapped in a bag of high-density cotton cloth or polyester cloth, attached to the lining with a fastener, velcro, or the like, and finished in a detachable uniform. In some cases, it is possible to insert a sheet-like object only in the front body, but it is preferable to attach it in a well-balanced manner in front, rear, left and right. Such uniforms include all uniforms of police officers, guards, etc., such as suit land and jumper type dispatch type.

The thus obtained uniform of the present invention has an effect that it can be stopped with a metal rope no matter what angle it is cut with a knife or knife.

The present invention will be described below with reference to the drawings.

FIG. 1 is a schematic view showing an example of a suit-type uniform of the present invention. This uniform 1 has a sheet-like material made of a metal rope attached to a front body 2 and a back body 3 with a velcro on a lining. The heart is strengthened by inserting a metal plate 4 into the chest.

FIG. 2 is a schematic view showing an example of a sheet-like material made of a metal rope. It is a sheet-like material made of cloth in which the high-strength yarns 6 are arranged in a ratio of three to one metal rope 5.

FIG. 3 is a schematic view showing an example of a sheet-like material made of a Russell knitted fabric into which a metal rope is inserted. A metal rope is inserted into a core thread, a Russell knitted fabric 7 in which a chain thread is knitted with a high-strength thread is expanded, and is fixed to a fabric 9 with a sewing thread 8.

[0021]

EXAMPLES The present invention will now be described specifically with reference to examples, but the present invention is not limited to these examples. Example 1 7 × 7 strands of stainless steel wire having a thickness of 0.1 mm were twisted,
A 1-mm-thick stainless steel rope composed of 49 strands was prepared. The density of the metal rope is 3 strands / cm with a warp warper.
20cN single yarn strength between metal ropes
/ Dtex, three para-type polyamide yarns having a total fineness of 1650 dtex are aligned and warped. The weft has a ratio of one metal rope and the three aramid yarns and a weft density of 30 / inch. A sheet made of a 1/3 twill fabric was prepared.

The woven fabrics were cut into four front and back-viewable shapes by a cutting machine, wrapped in plain woven fabric of polyester 165 dtex, and attached to the lining of ready-made clothes with Velcro.

The protective uniform thus obtained was attached to a Charpy tester, and a drop impact test was carried out by adjusting the load of the knife to 3 kg from a height of 50 c. The energy at this time was 15 joules.

As a result of evaluation, the surface cloth was cut, but the metal rope was not damaged at all and good results were obtained. In addition, put the blade of the knife to face up, 10cm speed with 300N force
As a result of evaluating the presence or absence of cutting when the protective uniform was pulled at / min, no cutting was observed. A duralumin board (Part No. 7075, 1.5m thick) to be inserted under the heart of the uniform
m) was evaluated with a tensile tester, and a penetration resistance value (maximum resistance value when penetrating) of the knife blade of 2000 N was obtained.
As a result, the heart portion was excellent in resistance to piercing of the blade, and the other portions were excellent in resistance to cutting. Moreover, the wearing feeling of the uniform was light, flexible, and good without discomfort. Example 2 In the same manner as in Example 1, a metal rope and para-based polyamide yarn were aligned in a 1: 3 arrangement, warped to a width of 30 cm, and a thin polyester adhesive interlining was laminated from the front and back to form a sheet. The sheets were stacked vertically and horizontally, wrapped in a bag, and attached to the back of the uniform with a zipper. The finished uniform is
It was produced at a lower cost than a woven fabric, and had a blade-proofing performance of 15 joules, which was excellent. However, it was slightly harder. Example 3 In the same manner as in Example 1, a carbon steel rope (0.8 mm thick, composed of 49 wires) coated with a nylon resin was used as a core yarn.
Single yarn strength 8cN / dtex, total fineness 1650dt for chain yarn
ex, a Russell knitted fabric with a mesh size of 10 mm was made with a high strength polyester yarn. After the finished knitted fabric was sewn around with the polyester fabric, it was attached to the lining of the uniform so that the Russell knitted fabric entered. The finished uniform was evaluated in the same manner as in Example 1, and a result of imperviousness was obtained with the energy of 15 joules of the knife. Further, a product more flexible than the woven fabric was obtained. Similarly, a knotless net was processed with a metal rope and polyester high-strength yarn, and almost the same product in terms of performance was obtained. Example 4 A stainless steel rope composed of 35 strands of 5 × 7 and having a thickness of 0.6 mm was alternately arranged with para-based polyamide yarns having a total fineness of 1650 dtex, and was placed on a 72-braid machine to obtain a density of 25. A book / inch combination was created. The finished assembly is passed through a resin impregnator to reduce the length to 50%, expand the width, and then impregnate the assembly with polyurethane resin. A 120 degree sheet was obtained. The braids were aligned and cut and sewn on the front body and the back body to complete a uniform. The finished uniform was thinner and more flexible than that of Example 1, and a blade-proof performance of 15 joules or more was obtained. Comparative Example 1 Five plain fabrics each composed of para-based polyamide yarn 1650 dtex were laminated, attached to the lining of the uniform, and sewn. The protective uniform thus obtained was attached to a Charpy tester, and as in Example 1, a drop knife was cut with a 15-joule energy to evaluate the knife, and as a result, a part of the knife was cut to the lining. Moreover, although it was flexible, it became heavy and the wearability was not preferable.

[0025]

According to the present invention, there is provided a material which has excellent blade-proofing property against slash, is lighter and thinner than conventional ones, is flexible, has no fatigue due to constant wearing, and can be protected more reliably and safely. can do.
