The water phase after cultivation can also be used.

Of the above, hinokitiol and its related compounds (commonly referred to as troborones-type compounds) are particularly preferably used mite-resistant or antibacterial components.

In the present invention, one of the tick-proof or antibacterial components as exemplified above, or a combination of two or more thereof can be used.

S of the anti-mite or antibacterial component to be adhered to or absorbed by buckwheat 5S is 0.0005 to 1%, preferably 0.001 to 0.5%. It is. As the water, pure water or ion-exchanged water can be preferably used, but natural water such as ordinary tap water or well water can also be used.

Organic solvents have good miscibility with anti-mite or antibacterial components such as methyl alcohol, ethyl alcohol, isoprovir alcohol (-2-propanol), ethyl ether, and acetone. A low-boiling solvent with affinity for water is present.

The mixture of the hydrophilic polymer and water used in the invention of the present invention may be, for example, water having a water temperature of 10 to 95, preferably 20 to 60, or a prepared mixture. On the other hand, it is prepared by mixing well using 0.7 to 1296, preferably 1 to 5%, of a hydrophilic high molecule of S. (Hereinafter, this will be referred to as the "first preparation liquid" in IE)

In the case of an aqueous mixture containing, in addition to the hydrophilic polymer, an anti-mite or antibacterial component in addition to the hydrophilic polymer used in the third invention, for example, the first SS S In addition, the anti-mite or anti-bacterial component is added to the prepared mixture in an amount of 0.005 to 4%, preferably 0.01 to 26. Prepare by mixing well. (Hereinafter referred to as “second preparation liquid”)

(Hereinafter referred to as "third preparation liquid")

The three types of preparations, the first preparation, the second preparation, and the third preparation, are collectively referred to as “preparation liquid”.

有機 An organic solvent may be used in combination with the first and second preparation liquids, and 、 3 Water may be used in combination with the preparation liquid.

The preparation solution used in the present invention is preferably a homogeneous solution. It can be in the shape of a sheet.

In the case of using the prepared liquid for spraying, the method of preparing the sake liquor may include mixing the prepared liquid with water or an organic solvent during the spraying process. is there. This method includes mixing the iS or the first preparation solution and the third preparation solution with water in the spraying process.

In the case of a preparation solution containing ¾molecules and semi-synthesis 髙 molecules, polymerization reaction of those monomers (eg, emulsion polymerization) or chemical reaction of W molecules (eg, There is also a method of directly preparing a preparation solution using the hydrolysis reaction of acrylic acid (2), and the reaction of vinyl alcohol as an esterification reaction). For example, the absorption method may be a method in which the prepared solution is subjected to sopa killing (hereinafter referred to as “immersion method” in the IE list below), or a method in which the prepared solution is added to the buckwheat husk. (In the following description, “8 & Cloth Method” is described as 2), but if it can adhere to or absorb buckwheat, the preparation method of the preparation solution, There is no particular limitation on the method of adhering or absorbing the substance and the amount used.

In the “clarification method”, as a guide, the prepared solution is 4 to 40 kg per mass (kg) of buckwheat (ic _ε >), preferably 5 to 30 kg, More preferably, it is 15 to 25 kg in the case of buckwheat S, in which sopa S is sufficiently immersed, and apparent specific gravity of 0.08 to 0.20.

Solution temperature, 0 to: 100 * C, preferably 100 to 90%, with stirring.

The mixing time should be at least as long as the time required to sufficiently adhere or absorb the prepared に on the saliva husk, usually 0.5 minutes to 2 hours, preferably 1 minute. Soak for about 30 minutes.

In this immersion process, it is of course possible to use ultrasonic waves.

Raise the buckwheat soaked in the prepared solution and use it attached to the buckwheat hulls after filtration. Rinse the used preparation solution and small pieces with a new preparation solution, rely on it, cut the liquid content to about 50 to 70%, and then dry. In the present invention, an ordinary method can be used. Among these, the gravitational filtration by a centrifugal separator can be preferably used.

The drying temperature is preferably from 25 to 90, more preferably from 40 to 70.

The drying time is determined by the water content of the treated buckwheat hulls or the water content of the buckwheat slaughter before treatment (water content at equilibrium moisture for buckwheat slaughter in a living environment: usually about 13 to 14 ¾. In the case of g, it is about 18¾, and when it is described as the water content of sopa killing before treatment, it indicates the water content of these.)

In the present invention, a normal drying method using a box-type air dryer, a rotary dryer, a stirring dryer, or a flash dryer can be used.

In the spraying method, as a guide, the mass (kg) of the preparation is 0.01 to: 10 kg per quality S (kg) of sopa husk, preferably 0.1 to 5 kg. Is spread in liquid or «form.

The time required for spraying should be longer than the time required for the preparation to sufficiently adhere to or absorb the buckwheat hulls. If is 0.5 minutes to 2 hours, preferably:! It takes about 30 minutes.

The application temperature of the preparation is from 0 to 100, preferably from 10 to 90.

If a large amount of the preparation is used and some of the preparation does not adhere to buckwheat hulls or remains unabsorbed, remove the excess and remove the small particles adhered to the buckwheat husks « Wash off with water and dry well.

The drying * temperature, drying time, and drying method may be the same as the dip method.

Spraying can be favorably incorporated into a series of manufacturing operations, such as: The contaminants are removed from the buckwheat obtained through the grain process by a sieving method or a mechanical separation method such as a boat separation method using the resistance of fluid.

Then, the purified S-only sorghum is usually exposed to 20 to 100, preferably 60 to 85, water using 15 to 25 kg of water per kg of buckwheat hulls. Wash in a washing tank covered with water for 0.5 hours to 60 minutes, preferably 1 minute to 30 minutes. In this immersion S washing step, it is possible to remove contaminants that adhere to buckwheat hulls and cannot be removed by the sieving method and water-soluble components during the killing of buckwheat. In this process, Sopa absorbs water, and after passing through gravity, the quality S increases about three times and the volume increases about twice. The cleaning water in the washing tank can be reused by circulating and purifying one part of the washing water.

This sopa husk is charged into a centrifuge «» and dehydrated until the water content becomes about 50 to 60%. After this water, there is almost no change in the degree of swelling of buckwheat. In addition, while spinning the centrifugal separator, the prepared solution is in a liquid state or in an 8? -Like or, preferably, in the form of a liquid that is localized on the rotating side wall surface from the rotation center line side. Spray. After swelling in advance in the immersion washing process in this way, the prepared solution is further dewatered using centrifugal force to kill sopa with a water content of about 50 to 60¾. Spraying makes it possible to absorb the water absorbed in the buckwheat hulls without replacing it with the prepared solution.

Furthermore, the use of centrifugal separation in the preparation solution processing step e can reduce the rotation speed and mix the inner and outer buckwheat effects. It can be spread to every corner.

If the treated buckwheat effect obtained in the preparation liquid treatment step is dried to a moisture level equivalent to buckwheat killing before treatment, the improved buckwheat hulls aimed at by the present invention can be obtained. Due to the sufficient mechanical separation method, it is possible to use the 60 ~ It is possible to save part of the energy required for drying and removing water from buckwheat killing containing about 70% of water.

As a mechanical separation method, for example, if $ body classifiers are used in a two-stage series, it is possible to remove foreign matter derived from unbeaten buckwheat and small animals with a large specific gravity in the first stage. In the second stage, so-called dry washing can be performed by removing actual crushed pieces and buckwheat hulls.

By spraying and drying the prepared liquid on buckwheat husks obtained by the dry washing, the energy required for drying can be reduced and improved buckwheat killing can be obtained.

(Hereinafter, dried buckwheat ¾ is distinguished by describing のもの 1 prepared solution as 笫 1 improved buckwheat hull, and using 2nd K solution as 「2nd improved buckwheat hull.

. )

In the invention of the present invention 5, as a guide, the quality of the first improved buckwheat killing S (kg) is preferably 0.05 to 10 g, preferably an anti-mite or antibacterial component. To absorb or absorb 0.01 to 5 g of the third preparation, use 0.05 to 5 k, preferably 0.07 to 3 kg of the third preparation. By the g¾ method or the spraying method, or preferably the spraying method, 53 third treated sodas are manufactured and then dried to obtain the desired buckwheat hulls. (Hereinafter, it will be referred to as "third improved buckwheat ¾J")

笫 3 The re-drying degree and drying time for obtaining the improved buckwheat drum are as follows.

The drying temperature is preferably from 20 to 70, more preferably from 30 to 50.

The drying time is about the time when the moisture content of the third treated buckwheat hulls becomes the moisture S for the killing of the saliva before treatment. (Hereinafter, the three types of the first treated buckwheat hull, the second treated buckwheat hull, and the third treated buckwheat hull, The three types of first improved buckwheat hull, second improved buckwheat 玆, and third improved buckwheat hull are collectively described as “improved buckwheat killing”. )

The improved buckwheat hull according to the present invention is more durable and more durable than buckwheat before treatment, so it is excellent in abrasion resistance and extremely little dust after long-term use.

Also, since the second and third improved buckwheat hulls are treated with an anti-mite or antibacterial component, the first improved buckwheat hulls are provided with anti-mite and antibacterial properties.

Combining a hydrophilic polymer and an anti-mite or anti-if component to kill buckwheat, i.e., buckwheat, a hydrophilic molecule, and an anti-mite or antibacterial component By combining these three types, the anti-mite and antibacterial effects have an unexpectedly long gun-holding property, and the second and 笫 3 improved Sopa are surprising. It is not clear that the invention is characterized by its long-term antiwear properties. This surprising effect is due to a combination of buckwheat hull, polyvinyl alcohol and hinokitiol by JIS, which suggests that the effect of hinokitiol can be maintained for a long time.

In addition, a comparison of the improved collar and untreated sopa shell shows that they have a refreshing sensation in terms of touch, gloss, fragrance, etc. due to the touch.

Therefore, the improved Soba ®, particularly the second and third improved Soba, obtained by the present invention can be suitably used as a filling material and a contacting material for S tools.

Above all, an improved soda obtained from a combination of a series of steps, such as a washing step, and a treatment step of a prepared solution by a spraying method using a centrifugal separation method, from buckwheat enamel which has been sieved and separated. It has better permeability than shells. Example
