Description

  The present invention relates to a camouflage fabric and a striped camouflage fabric that are difficult to recognize by visual observation and an infrared scope in a desert and a natural environment similar to a desert.

  A camouflage pattern that makes it difficult to distinguish from surrounding environments and objects is generally used as a cover fabric pattern covering clothes and various devices worn on the battlefield and the like. For example, the following Patent Document 1 proposes an invention relating to a camouflage processed nylon fabric dyed with an acid dye containing an infrared absorbing pigment. This fabric has a function to make the reflectance in the wavelength region of light including a specific wavelength region of infrared of 600 to 1200 nm in the same level as that of the natural world, and camouflage performance (imitation performance) ) Can be expressed. Further, it is known that the same effect can be exhibited by using a nylon or polyester fabric with a coating of a resin liquid containing an infrared absorber and print dyeing of a camouflage pattern.

  In the following Patent Document 2, an invention relating to a fabric made of fibers obtained by melt spinning a polymer mixed with an infrared absorber is proposed. By performing camouflage pattern print dyeing on this fabric, camouflage properties can be exhibited both for visual inspection and for searches using an infrared scope.

  However, by means such as print dyeing, both ends of a shaped product such as a narrow belt, particularly a belt-like product having a thickness of 1 mm or more, are not uniformly colored, so that sufficient camouflage performance can be achieved. Can not. For this reason, the camouflage property is ensured by covering the belt itself with a cloth in a situation where the necessary training is performed in a war zone or the like. However, there is a problem that slippage easily occurs between the fabric and the belt body, the gripping force of the buckle for tightening is difficult to stabilize, and the camouflage property is easily impaired due to dropping or breakage of the fabric.

  In order to solve this problem, in Patent Documents 3 and 4 below, four colors of original yarns obtained by melt spinning a polymer mixed with an infrared absorber and a colorant, or four colors of color obtained by dyeing the yarns are used. An invention has been proposed in which a yarn is jacquard processed to achieve uniform coloring even on a thick belt or the like.

Japanese Patent No. 3094130 Japanese Patent No. 3088264 Japanese Patent No. 4278165 Japanese Patent No. 5061256

  Up to now, an environment with trees such as a green field or a jungle is assumed as a battlefield, etc., camouflage pattern of a specification (hereinafter referred to as “jungle specification”) that can exhibit camouflage properties for such an environment, etc. Has been developed. However, in view of the recent world situation, the possibility that an environment such as a desert can become a battlefield is sufficiently assumed, and specifications that can exhibit camouflage properties in a natural environment that conforms to the desert and the desert (hereinafter referred to as `` There is a need to develop a camouflage pattern, etc.). For example, in the overseas dispatch of Self-Defense Force members and joint exercises with the US Army, there is a reality that jungle-equipped equipment cannot adequately respond. It is reported that the US military already has equipment that conforms to desert specifications as the main equipment.

  Assuming that it will be installed in the desert, etc., consider the characteristics required for the fibers (raw yarns) that make up clothes, fabrics, belts, etc., together with the characteristics of the colors of each color that make up the camouflage pattern. Is required. For example, a camouflage pattern that assumes a desert will be composed mainly of sand color, and it is difficult to fade even under severe direct sunlight. It is necessary to maintain a state that is difficult to recognize by the scope.

  The present invention has been proposed in view of the above circumstances, and an object of the present invention is to provide a camouflage fabric and a striped camouflage fabric that are difficult to recognize visually and by an infrared scope in a desert and a natural environment similar to a desert.

  The applicant arrived at the present invention as a result of diligent studies to achieve the above object. That is, the camouflage pattern fabric according to the present invention has a tensile strength of 7.0 cN / dtex or more, a strength retention of 500 hours of weathering treatment by an accelerated weathering test of 70% or more, and an evaluation by a fading fastness test of grade 4. It is the above, and is composed of an original yarn containing 0.2% by weight or more of titanium oxide and colored with a pigment and woven into a camouflage fabric having a multilayer structure by a jacquard loom. And

  Further, according to the present invention, in the camouflage pattern fabric, the hue (H) is 8.0 ± 1.5 YR, the lightness (V) is 6.5 ± 0.5, and the saturation (C) is 1 in the Munsell color system. Beige yarn that appears at a reflectance of 35 to 50% with respect to light in the wavelength range 1000 to 1200 nm, and H is 2.0 ± 1. 5Y, V is 5.2 ± 0.5, C is 2.5 ± 0.5, and it is a sand beige original with a reflectance of 25 to 40% for light in the wavelength range of 1000 to 1200 nm. In the Munsell color system, H is 2.0 ± 1.5 YR, V is 3.5 ± 0.5, C is 2.0 ± 0.5, and the color is 1000 to 1200 nm. The camouflage pattern is woven into a belt having a multilayer structure of three or more layers from an original brown yarn that appears at a reflectance of 10 to 25%. A belt-shaped camouflage characterized in that the surface is configured with an area ratio of 45% to 55%, 35 to 45% of the sand beige, and 10% to 20% of the brown. It is a patterned fabric.

  Moreover, it is preferable that the belt-shaped camouflage woven fabric is woven in a strip shape of 3 to 6 layers only from the beige original yarn, the sand beige original yarn and the brown original yarn.

  Here, the present invention has a constituent requirement that the tensile strength of the original yarn is 7.0 cN / dtex or more. This is because the solar radiation intensity in the desert is normally expected to be about 3 to 5 times that of the green space, and the accompanying strength deterioration is taken into account. In addition, the original yarn has a strength retention ratio of 500% or more in a weathering treatment by an accelerated weathering test of 70% or more and an evaluation by a fading fastness test of grade 4 or more. That is, not only the weather resistance and fading fastness but also the initial tensile strength of the original yarn is high.

  In addition, it is a constituent requirement that the original yarn contains 0.2% by weight or more of titanium oxide and is colored with a pigment. Nylon, polyester, and other fibers used in camouflage pattern tapes, belts, etc. (band-shaped camouflage pattern fabrics) that are planned to be applied as camouflage pattern fabrics are inherently glossy. % Or more (preferably 0.3% by weight or more) is contained to eliminate the glossiness. Furthermore, since the colored yarn formed by dyeing tends to be inferior in fading fastness, an original yarn obtained by mixing a pigment at the time of spinning is set as a constituent requirement in the present invention.

  The camouflage pattern fabric according to the present invention has high weather resistance and fastness to fading, and high initial tensile strength of the original yarn. The strength is further improved by using an original yarn colored with a pigment. Therefore, the present invention achieves the prevention of deterioration in the natural environment according to the desert and the desert where the solar radiation intensity is high by the above-mentioned original yarn, and it is difficult to be recognized by the visual and infrared scope over a long period of time, and has a camouflage property. A camouflage fabric with a camouflage pattern and infrared reflectivity can be achieved.

  Furthermore, if the belt-shaped camouflage pattern fabric according to the present invention is configured to have the parameters shown in [Table 1] below, from any point of view such as the HVC characteristics of each color, the pattern that appears on the surface, and the area ratio of each color. However, it will be possible to make it difficult to distinguish the surrounding environment from visual observation. Since the reflectance with respect to light in the infrared wavelength region of 1000 to 1200 nm is close to the infrared reflectance in the desert and the natural environment according to the desert, it is possible to satisfactorily exhibit the disguise for reconnaissance of the infrared scope.

  In addition, the belt-shaped camouflage woven fabric is woven into a strip shape of 3 to 6 layers only from a beige original yarn, a sand beige original yarn and a brown original yarn. It is possible to provide a belt-like camouflage fabric with an appropriate thickness according to the application product. In the case of a three-layer structure, the first three-layer structure in which the stacking order is beige, brown, sand beige from the lower layer to the upper layer, the second three-layer structure in which the beige, brown, sand beige, 3rd layer structure with the same sand beige, beige and brown, 4th layer structure with the same sand beige, brown and beige, 5th layer structure with the same brown, sand beige and beige, the same brown The belt-shaped camouflage woven fabric according to the present invention is formed by weaving including all six patterns of the sixth three-layer structure, which are beige and sand beige. While using these six patterns, it is preferable that the area ratio of brown in the middle layer of the three-layer structure is 60 to 70%. Since the present invention is processed by a jacquard loom, there is no problem such as uneven coloring at both ends. Further, an extra work such as covering the belt or the like with a cloth to ensure camouflage properties can be eliminated.

It is a front image which shows an example (imitation belt) of the strip-shaped camouflage pattern fabric which concerns on this invention.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodied embodiment of a striped camouflage fabric according to the present invention will be described with reference to the drawings. This embodiment is merely an example of the present invention, and various design changes can be made to the present invention without departing from the matters described in the claims.

  The camouflage pattern woven fabric according to the present invention is a strip-shaped camouflage fabric that uses a strip-shaped woven fabric having a thickness (for example, a thickness of 1 mm or more) such as a narrow belt or a camouflage pattern tape. As an example, the camouflaged belt 1 according to the present embodiment includes three kinds of original yarns including a beige original yarn, a sand beige original yarn, and a brown original yarn in three layers by a jacquard loom. It is woven into a belt with a camouflage pattern.

  As shown in FIG. 1, the beige area BE is 45 to 55% as a camouflage pattern, the sand beige area SB is 35 to 45%, and the brown area BR is 10 to 20% as a camouflage pattern. It is formed with an area ratio. In FIG. 1, the area ratio is 45% for the beige area BE, 40% for the sand beige area SB, and 15% for the brown area BR. By making the surface a camouflage pattern with such an area ratio, it is possible to provide a good disguise performance visually and make it difficult to distinguish the desert from the surrounding environment in a natural environment similar to the desert.

  As will be described later, the original yarns of the respective colors can be obtained by mixing the respective color pigments during spinning by melt spinning with a polymer. At the same time, it is preferable to further mix the infrared absorbing agent and the infrared reflecting material.

  The camouflage belt 1 according to the present embodiment has a good camouflage performance visually according to the HVC characteristics of each color shown in the following [Table 2] and the camouflage pattern that appears on the surface based on the area ratio of each color. This makes it difficult to distinguish from the surrounding environment in a natural environment. Moreover, since the reflectance of each color with respect to light in the infrared wavelength region of 1000 to 1200 nm shown in [Table 2] is close to the infrared reflectance in the natural environment according to the desert and the desert, it is impersonating the reconnaissance of the infrared scope. Can be exhibited satisfactorily.

  In addition, identification of HVC of each color and reflectance measurement in the infrared wavelength region were performed using a self-recording spectrophotometer UV3100 manufactured by Shimadzu Corporation.

  Next, in the camouflaged belt 1 according to this embodiment, the tensile strength of the original yarn of each color is 7.0 cN / dtex or more, and the strength retention after 500 hours of weathering treatment by the accelerated weathering test is all. A value of 70% or more is shown. Moreover, all the evaluation by a fading fastness test becomes 4th grade or more. The tensile strength of 7.0 cN / dtex or more is a tensile strength value (initial value) before various tests or at the time of product completion. Assuming that it is equipped in the desert, etc., the tensile strength in this application is 7.0 cN / dtex or more as sufficient strength to indicate that the fiber (raw yarn) has excellent weather resistance against severe direct sunlight. This is a requirement that should be prepared.

  The accelerated weather resistance test and the fading fastness test refer to tests using an accelerated weather resistance tester called a sunshine weather meter using a carbon arc as a light source. Tensile strength retention (%) is the breaking strength (kilonewton: KN) of the original yarn obtained by unraveling the imitation belt before the weathering treatment, and the original adhesion obtained by unraveling the imitation belt treated with a sunshine weather meter for 500 hours. The breaking strength (KN) of the yarn was measured under the conditions of a yarn length of 25 cm in accordance with JIS L 1013, an initial load of 0.05 kN, and a tensile speed of 30 cm / min, and this was calculated using the formula [Equation 1] below. It is a thing.

  The fastness to fading is determined by subjecting each color constituting the camouflage belt to a weathering treatment for 500 hours using the above accelerated weathering tester in accordance with the method specified in JIS L 0842. It was used and evaluated in 1-5 grade. The grades 1 to 5 using the gray scale are as follows. The first grade is the most fading and the fifth grade is the least fading. The first grade has faded to near colorlessness. The 2nd grade can confirm fading significantly. Even if you look away, you can see clearly. Grade 3 clearly shows fading. It can be determined even if you are away. Grade 4 is slightly fading. It is difficult to distinguish when looking away. Grade 5 is evaluated as having no fading before and after treatment.

  Hereinafter, a dummy belt is manufactured as an example of the present invention, and performance evaluation is performed using this belt as an example.

  First, for each color of beige, sand beige, and brown, a colorant (pigment), an infrared absorber, an infrared reflector, and a weather fastness improver for obtaining a desired color in advance are added with a high viscosity (Eater 1.45). 1.47 level) A virgin chip (in this embodiment, a polyester chip) is mixed to create a master chip for obtaining an original yarn. At this time, the concentration of the colorant (pigment) is adjusted so as to satisfy the value of the HVC characteristic in the above [Table 2] when the master chip is diluted 25 times to be the fiber of the original yarn. Infrared absorber is added in an amount of 0.010% by weight, titanium oxide having the function of an infrared reflector with a loss of glossiness is added in an amount of 5.0% by weight, and a fading fastness improving agent is added in an amount of 10.0% by weight.

  Next, virgin chips of the same type as those used to make the master chips are mixed so that the ratio of virgin chips: master chips is 24: 1, melted at 290 to 300 ° C. Spinning, winding the spun while being stretched by 4.5 to 5 times, to obtain an original yarn having a master chip diluted 25 times. For each color of beige, sand beige, and brown, the original yarn can be manufactured by the same method.

  The three kinds (three colors) of the original yarns thus produced are partially different in camouflage pattern between the front side (outside) and the back side (body side) of the camouflaged belt, and Jacquard weaving is performed so that the area ratio appearing on the surface satisfies the range specified in the above [Table 2] and becomes 100% as a whole. In the present invention, the surface means the outer surface of the camouflage belt (band-shaped camouflage fabric) as described above, and both the surface that faces the body when worn and the surface that faces outward are treated as the surface. .

  In the case of jacquard weaving, as shown in FIGS. 2 (a) to 2 (f), the first configuration example A in which the stacking order is beige, brown, sand beige from the lower layer to the upper layer, the beige, sand Second configuration example B to be beige, brown, third configuration example C to be the same sand beige, beige, brown, fourth configuration example D to be the same sand beige, brown, beige, same brown, sand beige, beige There are 6 patterns of weaving processing of 6th configuration F which becomes the 5th configuration example E, the same brown, beige and sand beige. In the present invention, all of these six patterns are used, and the surface area ratio value of each color in [Table 2] is set within the range, and jacquard weaving is performed to constitute a camouflaged belt. Furthermore, while using these 6 patterns, the area ratio of brown in the middle layer of the three-layer structure is 60 to 70%, and most of beige and sand beige appear on the surface. 2] is reliably provided.

  The polymer (virgin chip) used for the fiber as the material of the colored yarn constituting the camouflaged belt is preferably a polymer such as polyamide, polyester or polyolefin capable of forming a fiber. Specifically, nylon 6, nylon 66, polyethylene terephthalate, polybutylene terephthalate, polypropylene, polyethylene and the like can be exemplified. Further, the third component can be copolymerized or mixed within a range in which the properties of these polymers are not essentially changed.

  Examples of the infrared absorber to be mixed include carbon black, titanium black, and zirconium carbide. An infrared absorber containing a phthalocyanine compound can easily control the reflectance in a specific wavelength region. Examples thereof include PRO-JET925NP manufactured by FujiFilm. These compounds can be used alone or in combination. When 925NP is used, it may be used at a concentration of 0.001 to 0.01% by weight. If the amount is less than 0.001% by weight, the infrared absorption ability may be inferior and the camouflage performance may be insufficient. If the amount is more than 0.01% by weight, the cost becomes higher than the coloring effect, resulting in inefficiency. .

  Examples of the infrared reflecting agent include titanium oxide, aluminum oxide, zirconium oxide, and barium sulfate. These compounds can be used alone or in combination of titanium oxide and others. For example, when titanium oxide is used, it may be used at a concentration of 0.2 to 0.5% by weight. If it is less than 0.2% by weight, the camouflage performance may be insufficient, and if it exceeds 0.5% by weight, yarn breakage may easily occur during melt spinning.

  Furthermore, since titanium oxide has an effect of eliminating the glossiness of the fiber, it is effective for enhancing camouflage performance. In the present embodiment, titanium oxide manufactured by Ishihara Sangyo Co., Ltd. was used, and this function was exhibited as an infrared reflector and a glossy disappearance agent. In addition, for example, in the present invention, titanium oxide is used, and one or more of aluminum oxide, zirconium oxide, and barium sulfate is further included so that the total concentration is 0.2 to 0.5% by weight. Can do.

  As the fading fastness improving agent used for constituting the camouflaged belt of this embodiment, for example, TINUVIN 1577 (registered trademark) manufactured by BASF can be exemplified. The concentration may be 5.0-15.0% by weight.

  In addition to the infrared absorber, the infrared reflector, and the fading fastness improver, an additive that imparts antistatic properties, light resistance, heat resistance, and the like is included in the range of 0.1 to 0.5% by weight. Also good.

  The pigments that are colorants employed in this example are shown in [Table 3] below. Each is manufactured by Dainichi Seika Co., Ltd., and two types of each color are mixed to obtain a pigment. Colorants (pigments) are mixed when preparing a master chip for obtaining an original yarn. As described above, when the master chip is diluted 25-fold to form an original yarn fiber, the above [Table 2] The pigment concentration is adjusted so as to satisfy the value of the HVC characteristic at.

  Here, the performance evaluation of the strength retention and fading fastness of the original yarn of each color of beige, sand beige, and brown prepared as described above and Comparative Examples 1 to 3 was performed. ].

  In Comparative Example 1, a master chip was prepared in the same manner as in the present example, and a predetermined dye was used as a sand beige colorant to be mixed (in Comparative Example 1, the HVC characteristics of sand beige are as described above. It is adjusted so as to satisfy the values described in [Table 2]. Comparative Example 2 is an example in which a master chip was prepared in the same manner as in this example, and a beige original yarn was formed without using an infrared absorber.

  In Comparative Example 3-1, a master chip was prepared in the same manner as in this example, and a beige original yarn was formed without using TINUVIN 1577 (registered trademark) of BASF as a fading fastness improving agent. It is. Comparative Example 3-2 is an example in which a master bead was formed in the same manner as in this example, and a sand beige original yarn was constructed without using TINUVIN 1577 (registered trademark). Comparative Example 3-3 is an example in which a master chip was produced in the same manner as in this example, and a brown original yarn was formed without using TINUVIN 1577 (registered trademark).

  In addition, a 1.5 mm thick camouflaged belt (Example 1) was constructed by processing a single color jacquard from the original yarns of beige, sand beige and brown produced as described above, and the HVC characteristics of each color The results of the investigation are shown in [Table 5] below. In addition, as shown in FIG. 1, the area ratio of the camouflage belt of Example 1 is beige area BE45%, sand beige area SB is 40%, and brown area BR is 15%.

  FIG. 3 shows a graph comparing the reflectance of light in the infrared wavelength region near 1000 to 1200 nm between the portion where the surface of Example 1 is beige and the beige original yarn of Comparative Example 2. 4 shows the reflectance of light in the infrared wavelength region near 1000 to 1200 nm of the portion where the surface of Example 1 is sand beige, and FIG. 5 shows 1000 of the portion where the surface of Example 1 is brown. The reflectance of light in the infrared wavelength region near ˜1200 nm is shown.

  From the above [Table 4], [Table 5] and FIGS. 3 to 5, the false belt of Example 1 has an original yarn of each color having a tensile strength of 7.0 cN / dtex or more. It can be seen that the strength retention after 500 hours of the weathering treatment by the accelerated weathering test shows a value of 70% or more, indicating good weatherability. Evaluated by a fading fastness test has performance of grade 4 or higher and also has resistance to discoloration. In addition, the camouflage belt of Example 1 has a good camouflage performance visually due to the camouflage pattern that appears on the surface based on the HVC characteristics of each color and the area ratio of each color shown in [Table 2]. From FIG. 3 to FIG. 5, it is understood that the reflectance of each color in the infrared wavelength region of 1000 to 1200 nm satisfies the standard, and is close to the infrared reflectance in the natural environment according to the desert and the desert. It is understood that the disguise for reconnaissance can be demonstrated well.

  On the other hand, based on the above [Table 4], the sand beige original yarn of Comparative Example 1 used a dye, so the post-treatment strength (KN) was poor, the strength retention (%), and the color fastness. The value of is also bad. Therefore, in order to solve the subject of this application, it turns out that it is necessary to use a pigment for a coloring agent. In addition, since the beige original yarn of Comparative Example 2 did not use an infrared absorber, as shown in FIG. 3 and [Table 4], the infrared reflectance at 1200 nm was 52.4%, which was out of specification, There may be a problem in the disguise of the scouting of the infrared scope. Therefore, in order to solve the subject of this application, use of an infrared absorber is indispensable.

  Furthermore, since the original yarns of the respective colors of Comparative Examples 3-1 to 3-3 did not use a fading fastness improving agent, the fading fastness (KN) value was not only poor, but also the fading fastness value was poor. The strength retention rate (%) is also poor. Therefore, in order to solve the subject of this application, it turns out that it is necessary to use a fading fastness improving agent.

  It should be noted that the initial tensile strength (meaning before various tests and when the product is completed) is 7.0 cN / dtex or more, which should be provided as a premise when it is assumed to be equipped in a desert or the like. Since it was captured as the strength of the yarn, in the test results shown in [Table 4] above, all the original yarns of Examples and Comparative Examples are provided with a specification of a tensile strength of 7.0 cN / dtex or more. Similarly, titanium oxide is effective in further improving the camouflage performance due to the effect of eliminating the glossiness of the fiber, and therefore, all of the examples and comparative examples are provided with specifications including 0.5% by weight.

  Therefore, the present invention has a good disguise performance in an environment according to the desert and desert in terms of the HVC characteristics of each color appearing on the surface, the area ratio of each color, the reflectance of light with respect to the infrared wavelength range, etc. It can be made difficult to distinguish from the surrounding environment, and the disguise of the scouting of the infrared scope can be demonstrated well. Furthermore, the tensile strength is 7.0 cN / dtex or more, the strength retention of 500 hours of weathering treatment by accelerated weathering test is 70% or more, and the evaluation by fading fastness test is grade 4 or more. It is recognized that it has good weather resistance in the desert and the environment according to the desert due to the constitution comprising the original yarn containing 0.2% by weight or more and colored with the pigment.

  Here, in the above-described embodiment, the belt-like camouflage woven fabric woven into a three-layer belt from the beige original yarn, the sand beige original yarn and the brown original yarn has been described. Furthermore, the present invention also includes a belt-like camouflage fabric woven from these three colors of original yarns in a belt-like jacquard loom having a layer structure of 4, 5, or 6 layers.

  That is, various applications can be made by constructing a striped camouflage fabric having a multilayer structure of 3 to 6 layers from a beige original yarn, a sand beige original yarn and a brown original yarn prepared as described above. It is possible to provide a belt-like camouflage fabric having an appropriate thickness. At this time, by providing the belt-like camouflage fabric with the surface of the camouflage pattern having the HVC characteristics of each color and the area ratio of each color shown in the above [Table 2], good disguise performance is provided visually. Moreover, since it is woven from the three colored original yarns prepared as described above, the disguise for reconnaissance of the infrared scope can be exhibited well. Furthermore, it has a tensile strength of 7.0 cN / dtex or more, a strength retention of 500 hours or more in a weathering treatment by an accelerated weathering test of 70% or more, and an evaluation by a fading fastness test of grade 4 or more. It is recognized that it has good weather resistance in an environment according to the above.

  The present invention has been described in detail with respect to one of the embodiments that the applicant believes to be the best. However, the present invention is not limited to the above-described embodiment unless departing from the scope of the claims. Various design changes can be made without this. For example, in the above-described embodiment, the camouflaged belt has been illustrated and described. However, even a camouflage pattern tape having an adhesive layer on one side can be configured with the same performance.

  Moreover, for example, unless it deviates from the matter described in the claims, the present invention is not limited to the belt-like one, and can be applied to the entire camouflage fabric product. Even such fabrics have good disguise performance in deserts and desert-like environments in terms of HVC characteristics of each color appearing on the surface, area ratio of each color, reflectance to light in the infrared wavelength range, etc. Therefore, it is difficult to distinguish from the surrounding environment, and it is possible to make the disguise of the scouting of the infrared scope well. Furthermore, it will have favorable weather resistance in the desert and the environment according to the desert.

  Further, for example, when a belt-like camouflage woven fabric having a multilayer structure of 4 to 6 layers is formed, an original yarn other than the above-mentioned three colors is used unless the original yarn other than the above-described three colors such as black appears on the surface. It is possible to construct a belt-like camouflage pattern woven fabric according to the present invention by weaving a middle layer among 4 to 6 layers (including the uppermost layer on the surface and the layer excluding the lowermost layer). It is. By setting the area ratio of brown to 60 to 70% in any one of the intermediate layers among the 4 to 6 layers, most of beige and sand beige appear on the surface. The area ratio shown can be reliably provided. As a result, variations in the weaving method can be increased, and variations can be increased in terms of cost, product thickness, and the like.
