Bamboo heat-dried crushed material having a specific size does not scatter in the air, so it can be used for deodorant antibacterial products by laying or filling a part of the product.
Bamboo heat-dried crushed material having a specific small particle size is easy to apply or immerse into an object after being mixed with a liquid, so that it is easy to produce a deodorant antibacterial product.

  Examples of the bamboo used as a raw material for the heat-dried crushed bamboo of the present invention include, but are not limited to, bamboo belonging to the genus Poales Poaceae Bambusoideae Phyllostachys. As for the genus Mushroom, Mushroom (Phyllostachys bambusoides Sieb.et Zucc.), Moussouchiku (Phyllostachys heterocycla Mitf. .et Zucc.var. aurea Makino) and Phyllostachys makinoi Hayata. Of these genus, Mosouchiku is most preferably used. The Mosouchiku includes varieties such as Kikkochiku (Phyllostachys heterocycla Mitf. Var. Pubescens Ohwi cv. Heterocycla), Kinmeimosouchiku (Phyllostachys heterocycla Mitf. Var. Pubescens Ohwi cv. Nabeshimana) and the like. The part of bamboo used as a raw material is not particularly limited, but it is preferable to use the above-ground stem part. The reason for this is that when the ground stem portion of Moso bamboo is used, it is easy to produce the heat-dried crushed bamboo of the present invention and is excellent in deodorizing and antibacterial effects.

  The bamboo dried and dried crushed material of the present invention is produced by heating and drying at a temperature of at least 70 ° C. and 250 ° C. or less. If the temperature is lower than this temperature, drying is not sufficiently performed, so that a sufficient specific surface area cannot be obtained, and a deodorizing and antibacterial effect cannot be sufficiently imparted. On the other hand, if the temperature is higher than this temperature, the bamboo is carbonized and the bamboo has a dark brown color, and a white heat-dried crushed product cannot be obtained, which is not preferable.

The bamboo dried and dried crushed material of the present invention has a specific surface area of 0.5 to 10 m ² / g. The specific surface area is measured by a nitrogen adsorption / desorption method. In addition, the specific surface area of the bamboo dried at normal temperature, without performing the heat drying of 70 degreeC or more and 250 degrees C or less which is the process of this invention is about 0.3 m < ² > / g. When the specific surface area is less than the above range, the deodorizing and antibacterial effects are inferior compared with the case where the specific surface area is within the above range, which is not preferable.

Although the magnitude | size of the heat-dried crushed bamboo of this invention is not specifically limited, The heat-dried crushed material whose long side is 5-20 mm is used. This is because the heat-dried crushed material of this size does not scatter in the air and can be used in a method of being administered or filled into a part of the product. In this way, the bamboo heat-dried crushed material of the present invention can be suitably used as it is without being applied to the object. In addition, the long side here refers to the longer one of the length dimensions of the heat-dried crushed bamboo of the present invention.
Moreover, although a magnitude | size is not specifically limited, Preferably it is 0.01-1000 micrometers, More preferably, it is used as 0.1-500 micrometers. More preferably, it is 1-100 micrometers, Most preferably, it is 10-70 micrometers. This is because if the particle size of the heat-dried crushed material is less than 0.01 μm, the deodorizing and antibacterial effect is inferior, and if it exceeds 1000 μm, it tends to peel off when applied to an object. Thus, the heat-dried crushed bamboo of the present invention having this particle size can be suitably applied to an object and used.

The heat-dried crushed bamboo of the present invention is white. The white color includes yellowish white and brown white. In the Munsell color system, the white color indicates a range of hues 5YR to 5GY, lightness 7.0 or higher, and chroma 10.0 or lower.

In particular, it exerts an excellent deodorizing effect on ammonia that causes urine odor and meaty odor, pyridine contained in tobacco odor, butyric acid gas, and isovaleric acid gas that causes foot odor.
For example, a fabric to which 30 g / m ² of a bamboo heat-dried crushed material of the present invention is attached exhibits a 95% reduction rate (reduced from 100 ppm to 3.5 ppm) in 2 hours with respect to ammonia.

Furthermore, the bamboo dried and dried crushed material of the present invention has an excellent antibacterial effect.
For example, the fabric to which 30 g / m ² of the heat-dried bamboo crushed material of the present invention adheres meets the standards set by the Japan Textile Evaluation Technology Council (JTETC) and suppresses the growth of bacteria and has high antibacterial properties. Show the effect.

Hereinafter, the liquid deodorant antibacterial agent will be described.
The liquid deodorizing antibacterial agent of the present invention comprises a liquid in which the bamboo heat-dried crushed material of the present invention is mixed. Although the liquid used in order to mix the heat-dried crushing material of the said bamboo is not specifically limited, Water, an organic solvent, a polar solvent, a nonpolar solvent, etc. are mentioned.
Since the heat-dried crushed bamboo of the present invention is white, the desired deodorant and antibacterial effect can be obtained without substantially affecting the color of the liquid deodorant antibacterial agent itself.

The amount of bamboo dried and dried crushed material contained in the liquid deodorant antibacterial agent is not particularly limited, but is preferably 1 to 70% by weight, more preferably 3 to 50% by weight, and most preferably 5 to 40% by weight. A liquid deodorant antibacterial agent containing 1 to 70% by weight of bamboo dried and dried by heating is excellent in fluidity. For example, when the surface is applied to a smooth coating, a smooth coating surface is formed. Can do. In addition, work efficiency is improved because it is easy to paint.
Moreover, when the particle size of the bamboo heat-dried crushed material contained in the liquid deodorizing antibacterial agent is small, for example, when the particle size is 0.01 μm to 100 μm, the bamboo heat-dried crushed material cannot be confirmed even in appearance. Therefore, it can be used for all purposes.

  Examples of the liquid deodorant antibacterial agent of the present invention include, but are not limited to, paint agents, printing agents, dye agents, coating agents, and inks.

Hereinafter, the deodorizing antibacterial material will be described.
The deodorant antibacterial material of the present invention is a paper material or a fiber material that holds the bamboo dried and dried crushed material of the present invention on the surface and / or inside. Since the deodorizing and antibacterial material of the present invention retains the bamboo dried and dried crushed material, it has excellent deodorizing and antibacterial effects. Moreover, since the heat-dried crushed bamboo contained in the deodorant antibacterial material is white, the appearance of the deodorant antibacterial material is not impaired.

When the deodorized antibacterial material of the present invention holds bamboo dried and dried crushed material on the surface, the amount of bamboo dried and dried crushed material is not particularly limited, and may be appropriately determined according to the use, preferably It is 1-500 g / m < ² >, More preferably, it is 5-200 g / m < ² >, Most preferably, it is 10-100 g / m < ² >.
If the content of the bamboo heat-dried crushed material is less than 1 g / m ² , a sufficient deodorizing effect cannot be obtained, and if the content exceeds 500 g / m ² , the bamboo heat-dried crushed material becomes paper. Or, since it becomes easy to peel off from the fiber material, either case is not preferable.

When the deodorized antibacterial material of the present invention holds bamboo heat-dried crushed material on its surface, the deodorized antibacterial material of the present invention may hold bamboo heat-dried crushed material uniformly on the entire surface. Moreover, the deodorizing antibacterial material of this invention may provide the part which does not hold | maintain the part which hold | maintains the heat-dried bamboo crushed material on the surface, and may form a pattern further.
Moreover, the deodorizing antibacterial material of this invention may provide both the part and pattern part which hold | maintain the heat-dried crushed material of bamboo uniformly on the surface, and may form one surface.

  If a portion for holding and not holding a bamboo heat-dried crushed material is provided on the surface of the deodorant antibacterial material, a convex portion is formed in a portion for holding the bamboo heat-dried crushed material. Thereby, a frictional force can be produced between the convex part with which a deodorizing antibacterial material is provided, and the object which this deodorizing antibacterial material contacts, and the anti-slip effect is acquired.

Moreover, the deodorizing antibacterial material of this invention can form a pattern by the said convex part on the surface. For example, the convex portions can be formed in a matrix (see FIG. 15), that is, a matrix pattern can be formed. With this matrix pattern, a further excellent anti-slip effect can be obtained. The reason for this is that a high frictional force is generated between an object in contact with the deodorant antibacterial material by regularly forming convex portions provided on the surface of the deodorant antibacterial material.
For example, when such a deodorizing and antibacterial material is an artificial anus covering bag, when it is used overlapping with vinyl (artificial anus stoma), etc., it is caused by the frictional force generated between the convex part of the artificial anus covering bag and the vinyl. Can prevent slipping of vinyl.

  Moreover, the deodorant antibacterial material provided with the part which hold | maintains the heat dried crushed material of bamboo on the surface, and the part which does not hold | maintain does not impair the air permeability and water absorption of a deodorant antibacterial material.

  The deodorant antibacterial material of the present invention is a paper material or a fiber material. The fiber material is not particularly limited, and examples thereof include cellulosic fibers produced from natural plant fibers, or cotton, hemp, fabric, wool, polyethylene, rayon, nylon, silk, and acrylic.

The fiber material containing the bamboo dried and dried crushed material of the present invention does not deteriorate its deodorizing effect by washing. For example, a fabric (100 cm ² ) holding 30 g / m ² of bamboo by heat-dried crushed material is reduced by 66% (reduced from 100 ppm to 25 ppm) in 2 hours with respect to ammonia even after 10 washes. Indicates.

There is no particular limitation on the method of holding the bamboo dried and dried crushed material on the surface and / or inside the deodorant antibacterial material of the present invention.
For example, when the deodorizing antibacterial material of the present invention is a fiber material, the deodorizing antibacterial material is produced by weaving bamboo heat-dried crushed material into the fiber material.

For example, when the deodorizing antibacterial material of the present invention is a paper material or a fiber material, the deodorizing antibacterial material is produced by the following steps (a) to (c).
(A) Step of preparing a liquid deodorant antibacterial agent (method described above)
(I) The step of applying the liquid deodorant antibacterial agent obtained in the step (A) to the surface of the paper material or fiber material, or the step of immersing the paper material or fiber material in the liquid deodorant antibacterial agent (C) step (I) Process to obtain deodorant antibacterial material by drying paper or fiber material obtained in

In the step (b), the method of applying the liquid deodorant antibacterial agent to the surface of the paper material or fiber material or immersing the paper material or fiber material in the liquid deodorant antibacterial agent is not particularly limited, Dyeing methods applied to fibers and fabric materials can be applied. That is, by using the liquid deodorant antibacterial agent of the present invention instead of the dyeing solution used in a general dyeing method, the bamboo and heat dried crushed material of the present invention can be held on the fiber and fabric materials. .
For example, examples of the dyeing method include dip dyeing in which fibers and fabric materials are immersed in a dye solution, and printing. The dyeing is performed using water as a medium, and the printing is performed using paste as a medium. In the present invention, among these, textile printing is preferably employed (detailed later).

  By drying the paper material or the fiber material obtained in the step (I) in the step (C), it is possible to make it difficult to peel off the heat-dried crushed bamboo of the present invention.

Hereinafter, the textile printing will be described.
Printing is generally referred to as printing, and a pattern is created by printing a dyed solution prepared by combining a paste and dyeing solution onto a fabric or the like (fabrics or products (products made of materials other than fabric)). It is a staining method. The above-mentioned printing means an operation of placing a dye solution at a certain thickness on a portion where a pattern of a fabric is to be printed using a printing plate. Thereafter, the pattern can be fixed by performing steaming heat treatment.

  The printing used in the present invention uses a dye solution containing the paste and the heat-dried crushed material of the bamboo of the present invention (that is, the liquid deodorizing antibacterial agent according to the present invention). It is a method of fixing things together. Colorants (dyes and pigments) can be optionally added. The paste is usually not limited as long as it is a resin used for a cloth, but an acrylic or the like is preferably used.

The reason why the textile printing is suitably used is that the textile can be firmly attached to the deodorized antibacterial material by heat-dried bamboo of the present invention. Thereby, when the deodorizing antibacterial material is a fabric, for example, the bamboo dried and dried crushed material is not peeled off from the deodorizing antibacterial material even after multiple washings.
In addition, when bamboo heat-dried crushed material is attached to a deodorant antibacterial material by printing, it is excellent in that it can impart an anti-slip effect to the deodorant antibacterial material.

The case where the deodorant antibacterial material of the present invention is an artificial anus covering bag will be described as an example, and a method for holding a bamboo dried and dried crushed material in an artificial anus covering bag by printing will be described below.
Place the printing plate on top of the fabric that will be inside the colostomy bag. A dye liquor containing paste and heat-dried crushed bamboo of the present invention is prepared and applied from above the printing plate. This printing plate is engraved in a mold in which the applied dyeing liquid forms a plurality of matrix-like convex portions on the colostomy bag. Thereafter, by performing steaming heat treatment, a plurality of convex portions including bamboo dried and dried crushed material can be fixed to the surface of the artificial anal capsule bag.
Since the artificial anal capsule bag manufactured in this way is provided with a plurality of convex portions on the inner surface of the artificial anal capsule bag, slipping of the vinyl can be prevented when vinyl (artificial anal stoma) is overlapped.

  The printing method is not limited to the method using the printing plate, and inkjet printing can be used based on the same technical idea. That is, using a printing machine for ink jet textile printing, a dye containing heat-dried bamboo can be fixed on a deodorizing antibacterial material such as cloth.

  When the deodorant antibacterial material of the present invention is a paper material, the method for holding bamboo dried and dried crushed material is not particularly limited. For example, an ink jet printer may be used to print on paper as characters, pictures, and the like. Alternatively, during the process of manufacturing Japanese paper, the bamboo dried and dried crushed material of the present invention is mixed (that is, the bamboo dried and crushed bamboo is contained in the water containing the raw material fibers, and is then sown). May be.

Next, the deodorant antibacterial product of the present invention will be described. The deodorized antibacterial product of the present invention refers to a product produced by using the bamboo dried and dried crushed material or the deodorized antibacterial material as one of the components.
The deodorized antibacterial product of the present invention has white dehydrated dried bamboo and can be easily dyed in a desired color, so that it can obtain an excellent deodorant and antibacterial effect without impairing the appearance of the product. Can do.

The deodorant antibacterial product of the present invention is a product that requires a deodorant and antibacterial effect in clothing products, animal products, care products, medical products, bedding products, interior products, daily products, and foods.
Examples of the above are listed below, but are not limited thereto. Examples of the clothing article include uniforms, exercise clothes, and hats. Examples of the animal supplies include animal clothing, animal rugs, animal coverings, and animal breeding sheds. Examples of the medical supplies include an artificial anal covering bag. Bedclothes include futons and pillows. Examples of the interior article include a face material, a film material, a curtain, a cushion floor, a wall cloth, a wallpaper material, a mat, a carpet, a shoji, and a bag. Examples of the daily necessities include packaging materials, bags, calendars, colored paper, stationery, and plastic containers. Examples of the food include beverages, strawberries, and pet food.

What is necessary is just to select the magnitude | size of the heat-dried bamboo crushed material used for a deodorant antibacterial product according to a use application.
For example, a heat-dried crushed product having a long side of 5 to 20 mm can be used by charging or filling a part of the product. This is because the heat-dried crushed material of this size does not scatter in the air.
As an example, a heat-dried crushed material having a long side of 5 to 20 mm is suitably used for an animal breeding shed. For example, in a certain animal breeding shed, a part of the shed (second unit) can be pulled out from the main body (first unit) to secure a playground space, and bamboo dried dried bamboo is put under the floor of the first unit. A drawer member is provided. Specifically, the first unit includes a bottom plate member, a caster, a column member, a back panel, a side surface right panel, a side surface left panel, a top frame member, and a top plate member. The second unit includes a front panel, casters, a slide right panel, a slide left panel, a fixing material, a slide bottom plate member, a stopper, and an auxiliary plate member. The second unit can be accommodated in the first unit because it can slide back and forth along the slide groove of the top frame member of the first unit. Since the drawer member can slide back and forth along the slide groove of the bottom plate member of the first unit, it can be accommodated under the main unit.
This breeding shed can be provided with a deodorizing and antibacterial effect by putting heat-dried crushed bamboo into the drawer. As a result, the odor of the pet and the odor of the excrement of the pet are reduced, and it becomes possible to coexist comfortably with the pet as a member of the family.

For example, bamboo dry dried crushed particles with a particle size of 0.1-500 μm can be applied to various paper or fiber materials as described above by making it liquid (liquid deodorizing antibacterial agent), and deodorizing antibacterial products. Easy to use.
Furthermore, bamboo dried and dried crushed material having a particle size of 0.1 to 500 μm can be added to foods or beverages. Ingesting the food and drink has the effect of reducing the symptoms of asthma and hay fever, and has the effect of reducing fatigue. Moreover, when a smoker ingests these food and drink, there exists an effect | action that nicotine is discharged | emitted from a body. Furthermore, it has the effect of keeping a pet's intestine beautiful by mixing with pet food and making a pet ingest. For example, the bamboo dried and dried crushed material is mixed with plastic to produce a plastic container, whereby food can be suitably stored. That is, the odor of food can be reduced and the antibacterial effect can be exerted by the heat-dried crushed bamboo contained in the plastic.

Hereafter, the manufacturing method of the heat-dried crushed bamboo of this invention is demonstrated.
The bamboo heat-dried crushed material of the present invention is produced by heat-drying bamboo at a temperature of 70 ° C. or higher and 250 ° C. or lower. The heat drying means that the bamboo is dried by heating the bamboo at least 70 ° C. or more and 250 ° C. or less. The heat-dried crushed bamboo is characterized by having a specific surface area of 0.5 to 10 m ² / g and white.
Furthermore, although the heat-dried crushed bamboo of the present invention is produced by a heat-drying step and a crushing step, either the heat-drying step or the crushing step may be performed first.

As an example of the production method, production method 1 and production method 2 (hereinafter, shown as a reference example) will be described.
<Production method 1>
Bamboo heat-dried crushed material can be produced by the following steps (1) to (7).
(1) Step of applying bamboo vinegar solution on the ground stem of bamboo and drying (2) Step of placing the bamboo obtained in step (1) in the kiln (3) Step of placing the bamboo obtained in step (2) of the kiln After heat-treating at 200-250 ° C., heat-treating at 150-190 ° C. (4) Obtaining bamboo obtained in step (3) by preheating (5) Obtained in step (4) The step of removing the bamboo from the kiln after the temperature difference between the inside of the kiln and the outside air is 20 ° C. or less (6) The step of drying the bamboo obtained in the step (5) (7) The step (6) Crushing the inner part of the bamboo surface obtained by removing the carbonized surface to obtain a heat-dried crushed bamboo product

  Step (1) is performed in order to make the wrinkles in the bamboo inconspicuous and make the finished color uniform.

  In step (2), the bamboo is placed in the kiln, whereby all the bamboo is baked substantially evenly in the next step (3). Specifically, the longer the moisture content (water content), thickness, and weight of bamboo, the longer it takes to burn (carbonize). In order to eliminate this, bamboo is arranged according to the temperature distribution of the kiln in which the temperature inside the kiln is higher from the lower part of the kiln and deeper from the front (entrance side).

  As a kiln used for baking bamboo, as shown in FIGS. 1 and 2, a kiln 10 made of iron or the like and having a clay surface on its surface and having a substantially dome shape can be used. Inside the kiln 10, a rail 12 extending by a length equal to a substantially diameter (for example, about 3 m) is laid from the entrance 11 to the back, and a carriage 13 can travel on the rail 12. The carriage 13 has shelves 14a to 14c in multiple stages, and a bamboo 15 can be placed on each shelf. Although not shown, the inlet 11 can be sealed with an iron door or the like. Although not shown, a temperature sensor is installed on the ceiling of the kiln 10 and a temperature display unit for visually confirming the temperature measured thereby is provided on the outer wall of the kiln 10. This can be used when controlling the temperature in the kiln 10.

  When the step (3) is performed using such a kiln 10, the bamboo 15a1 has a higher temperature than the bamboo 15a1 disposed at the back of the uppermost shelf 14a and the bamboo 15a2 disposed at the frontmost side. . Similarly, when the bamboo 15b1 disposed at the innermost shelf 14b is compared with the bamboo 15b2 disposed at the frontmost side, the temperature of 15b1 is higher. Similarly, when the bamboo 15c1 disposed at the back of the lowermost shelf 14c is compared with the bamboo 15c2 disposed at the frontmost side, the bamboo 15c1 has a higher temperature. Moreover, if the arrangement position of the kiln 10 in the depth direction is the same, the bamboo placed on the uppermost shelf 14a has the highest temperature, and the bamboo placed on the lowermost shelf 14c has the slowest temperature rise. Become. Therefore, according to the temperature distribution in the kiln 10, the bamboo with a large moisture content / thickness / weight is arranged at a position where the temperature in the kiln becomes high, and the bamboo with a small moisture content / thickness / weight is placed in the kiln. It arrange | positions in the position where temperature becomes comparatively low.

  Step (3) is a step of baking (partially carbonizing) a large number of bamboos 15 placed in the columns 14a to 14c of the carriage 13 in the kiln 10 using fuel such as wood pieces and bamboo pieces, It is executed under temperature control as shown in FIG. The fuel is not particularly limited, but because bamboo contains a lot of oil, bamboo pieces are used when baking at high temperatures (eg, 200 ° C. or higher), and wood pieces are used when baking at medium temperatures (eg, 150-200 ° C.). When baking at a low temperature (for example, 150 ° C. or lower), it is preferable to use logs of raw wood.

Step (3) includes the following steps (3-a) to (3-d).
(3-a) Step of charging fuel into the kiln and burning it to raise the temperature in the kiln to temperature T1 in a short time (3-b) Intermittently fueling and maintaining T1 for about 30 minutes (3-c) A step of stopping the fuel injection and lowering the temperature of the kiln to T2. (3-d) A step of performing fuel injection and maintaining the temperature T2 for a predetermined time.

Referring to FIG. 3, a necessary amount of fuel such as a piece of wood is introduced from an inlet 11 into a kiln 10 containing a large number of bamboos 15. Then, this fuel is burned, and the temperature in the kiln 10 is rapidly raised in a short time to a temperature T1 (3-a). The temperature T1 is 200 to 250 ° C., and can be set to 230 ° C., for example. To raise the temperature to such a high temperature T1 at once, for example, within 30 minutes after the start of combustion, a large amount of bamboo pieces are used as fuel in consideration of the capacity of the kiln 10 and the water content and quantity of the bamboo 15. Can be easily implemented. If necessary, the fuel is intermittently supplied several times.
If the temperature T1 exceeds 250 ° C. in this step, the bamboo bursts in the kiln and carbonizes to the inner surface of the bamboo to exhibit a dark brown color, which makes it impossible to obtain a white crushed material. Moreover, when temperature T1 is less than 200 degreeC, since drying is not enough and a deodorizing and antibacterial effect also become inadequate, it is unpreferable.

  Next, this high temperature state T1 is maintained for about 30 minutes, preferably 15 to 60 minutes (3-b). In order to maintain the high temperature state T1, the fuel is intermittently supplied. The time from the start of combustion to the end of the 3-b step is preferably about 30 to 60 minutes.

  Thereafter, the fuel injection is temporarily stopped and the temperature of the kiln 10 is lowered to T2 (T2 <T1) (3-c). The temperature T2 is 150 to 190 ° C, preferably 170 to 180 ° C. The time required for the temperature drop 3-c is 10 to 30 minutes, preferably about 15 minutes.

Next, the kiln 10 is maintained in this temperature range T2 for a predetermined time, for example, 15 to 45 minutes, more preferably 20 to 40 minutes (3-d). For this purpose, the fuel is introduced intermittently.
If the steps 3-c and 3-d are not performed, the bamboo is not dried evenly, and sufficient deodorization and antibacterial effects cannot be obtained.

  In step (4), the fuel input is stopped and water remaining in the bamboo is removed by residual heat. Although this operation depends on the capacity of the kiln 10 and the like, it is carried out for almost a day and night, during which most of the water remaining on the bamboo is removed and dried.

  In step (5), it is confirmed that the difference between the temperature (T3) of the kiln 10 and the outside air temperature is 20 degrees or less, and the dried bamboo is taken out from the kiln 10. This operation can be performed by pulling out the carriage 13 along the rail 12 from the kiln 10.

  Bamboo is dried by a series of operations from step (3) to step (5). For example, after starting combustion at 10:00 am, performing 3-a for 20 minutes, 3-b for 30 minutes, 3-c for 15 minutes, and 3-d for 30 minutes, and then performing additional heat treatment in step (4) until the next morning It is allowed to cool and the bamboo dried in step (5) is taken out. In this way, dried bamboo can be repeatedly produced in a daily cycle.

  In step (6), the bamboo is further dried outside the kiln. As a period required for drying, it is preferable to leave it to dry for about 6 months in a place with low humidity. By this step, the water content of the bamboo is removed so that the water content of the bamboo is 10.0% or less, preferably 8.0% or less. Thus, by reducing the moisture content of bamboo, generation of mold can be suppressed.

The bamboo obtained in the step (6) is carbonized in the surface portion and has a brown color, but the inner portion has a white color. In step (7), the bamboo from which the carbonized surface portion has been removed is crushed to produce a white bamboo heated and dried crushed product.
In the step (7), a powdered bamboo heat-dried crushed product can be produced by crushing until the particle size of the bamboo heat-dried crushed material becomes 0.1 to 500 μm.
The specific surface area of the heat-dried bamboo dried product obtained in the step (7) is 0.5 m ² / g or more. Specifically, it is in the range of 0.5 m ² / g or more and less than 1.0 m ² / g.

<Production method 2>
Bamboo heat-dried crushed material can be produced by the following steps (A) and (B).
(A) Step of crushing bamboo ground stem (B) Step of placing bamboo obtained in step (A) in a kiln and drying it while heating at 70 to 120 ° C. to obtain a heat-dried crushed bamboo product

In step (A), the bamboo ground stem is crushed. The crushed bamboo may be of a size that can be dried in a sufficiently short period, but the long side is preferably 5 to 20 mm. If it is smaller than 5 mm, the crushed material is scattered in the kiln, and it becomes difficult to handle. On the other hand, if it is larger than 20 mm, drying is not sufficiently performed in a short period of time, which is not preferable.
By the step (A), the time required for drying in the step (B) can be shortened, and the heat drying treatment can be performed efficiently.

A process (B) is a process of heat-drying the bamboo crushed material in the range of 70-120 degreeC. The drying time is preferably 3 to 30 hours, more preferably 8 to 15 hours.
The bamboo to be dried by heating in this step (B) has a smaller shape than the bamboo in the steps (3) and (4) of the production method 1, and therefore has a large surface area in contact with air in the kiln. Therefore, although the temperature in the kiln of a process (B) is low, the water | moisture content contained in a bamboo evaporates comparatively early.
By this step, the moisture of the bamboo is removed, and the moisture content of the bamboo is set to 8.0% or less, preferably 6.5% or less. By reducing the water content of bamboo, the generation of mold can be suppressed.
The specific surface area of the heat-dried bamboo crushed material obtained in the step (B) is 1.0 m ² / g or more. Specifically, the range is 1.0 m ² / g or more and 10 m ² / g or less.

The heat-dried crushed bamboo produced by the production method 2 may be used as it is, or may be used in the form of powder by the following step (C).
(C) A step of crushing the bamboo obtained in step (B) until the particle size becomes 0.1 to 500 μm.

  In the step (7) of the production method 1 or the step (C) of the production method 2, the method of crushing bamboo into a powder form is not particularly limited, but it is preferably performed by pulverization. As the pulverization treatment, for example, a pulverizer that performs physical pulverization such as a hammer mill, a cutter mill, an air jet mill, a beating machine, a stone mill, or a fiber crusher can be used. Alternatively, bamboo fiber swelling agents such as water and chemicals may be used. It can also be mechanically pulverized while being heated and humidified with steam or the like.

  Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.

30 g of the obtained sample of Reference Example 1 was used.
A white rayon cloth (100 cm ² ) was used as a comparative control.

(Antimicrobial evaluation test)
A method based on JIS L 1902 “Test method for antibacterial properties of textile products” was used. This test method inoculates a test piece that has been antibacterial processed and an untreated comparison control with bacteria, measures the number of viable bacteria after culture, and shows the difference in the number of viable bacteria compared to the untreated product comparison control Is.

The bacteria used in this test were Staphyococcus aureus (JCM No. 2151) and Klebsiella pneumoniae (IAM 12015).
First, 10 ml of Nutrient liquid medium was placed in each of two L-shaped tubes, and S. aureus and Klebsiella pneumoniae were inoculated into each tube. After shaking culture at 37 ° C. for 18 hours, the concentration of the bacteria inhabiting the medium was measured and used as the initial number of bacteria.

At the same time, in each of Staphylococcus aureus and Klebsiella pneumoniae, placed 10 ⁴ or so bacteria culture solution having a concentration of usually 1/40, the test piece 4, planted on a comparison between on the sample of Reference Example 1 Fungus. After culturing in a 37 ° C. incubator for 18 hours, the bacteria were washed out with 20 ml of physiological saline. From that, 1 ml was taken out, a dilution series was prepared, and the number of surviving bacteria was examined (viable cell count). Moreover, the proliferation value, the bacteriostatic activity value, and the bactericidal activity value were calculated by the method described later. The results are shown in Table 12.

(Calculation method of growth value, bacteriostatic activity value, bactericidal activity value)
Based on the viable count, the growth value, bacteriostatic activity value, and bactericidal activity value are calculated.
The calculation method is shown below. When the number of viable bacteria after culturing was less than 10, the number of viable bacteria was calculated as 10.
Growth value = log (number of viable bacteria on the control after 18 hours of culture) −log (number of initial bacteria)
Bacteriostatic activity value = log (number of viable bacteria on control after 18 hours of culture) −log (number of viable bacteria on test piece after 18 hours of culture)
Bactericidal activity value = log (initial number of bacteria)-log (number of viable bacteria on the test piece after 18 hours of culture)

Refer to Table 12. According to the standards established by the Japan Textile Evaluation Technology Council (JTETC), bacteriostatic activity values of 2.2 or more and bactericidal activity values of 0 or more are considered to be antibacterial. Also, the higher the value, the better the antibacterial properties. If the growth value is greater than 1.5, the test is considered valid.
For test piece 4, the bacteriostatic activity value is 6.40 for Staphylococcus aureus and 6.68 for Klebsiella pneumoniae, both being 2.2 or more. This bactericidal activity value is 3.49 for Staphylococcus aureus and 4.03 for Klebsiella pneumoniae, both of which are 0 or more.
For the sample of Reference Example 1, the bacteriostatic activity value is 4.56 for Staphylococcus aureus and 6.08 for Klebsiella pneumoniae, both being 2.2 or more. This bactericidal activity value is 3.02 for Staphylococcus aureus and 3.51 for Klebsiella pneumoniae, both being 0 or more.
Therefore, it was shown that the heat-dried crushed bamboo of the present invention satisfies the standards set by the Japan Textile Evaluation Technology Council (JTETC) and has high antibacterial properties by suppressing the growth of bacteria.
