業上完全に防ぎ止めることができなかつた。 Filtration of liquids containing activated carbon for decolorizing liquid products and adsorbing impurities in products is widely used in alcoholic beverages (sake, grape wine, whiskey, beer, etc.), various soft drinks, pharmaceuticals, and chemical products. . Diatomaceous earth and asbestos have traditionally been used as materials, but they suffer from clogging and slow overspeed.
It had drawbacks such as poor overefficiency. Furthermore, when a material layer using asbestos is used, it has not been possible to completely prevent a very small amount of asbestos from being mixed into the liquid in actual work.

は不向きと考えられる。 It is known from Japanese Patent Publication No. 52-32479 that a beverage can be prepared using split fibers of a polyolefin containing 5% or more of polyvinyl alcohol, but the split fibers of the film have a small surface area per unit weight, so the overefficiency is low. Unfortunately, it has the disadvantage that it is slow to develop in water because it contains a lot of polyvinyl alcohol.
Furthermore, when hot water or hot alcoholic water is passed through split fibers that contain a large amount of polyvinyl alcohol, polyvinyl alcohol is detected in the liquid, and the Ministry of Health and Welfare's Sanitary Testing Methods, Packaging Materials Act No. 434 Considering the number, it is considered to be particularly unsuitable for drinking alcoholic beverages.

つ。 The present invention has been made to solve the problems of these conventional methods, and is to produce a polyolefin fibrous material (flat) obtained by jet-spinning a polyolefin solution or emulsion under high temperature and high pressure into a low pressure region. Because fibers (fibers, fibrids) are used, the surface area of the fibrous material is extremely large, and the strong surface activity of the fibrous material greatly contributes to excessive liquid adsorption and is useful for increasing the liquid purification effect.

４mm、表面積が0.3ないし25m2/ｇのものである。 The polyolefin fibrous material used in the present invention is a solution obtained by dissolving polyolefin such as polyethylene or polypropylene in a solvent such as hexane, heptane, benzene, or toluene at a high temperature, for example, at a high temperature of 100°C or higher, or Furthermore, an emulsion obtained by adding a solvent that is difficult to mix with the above solvent, such as water, can be spouted into a recovery drum at a low pressure region, for example, at room temperature and pressure. By appropriately selecting the concentration of polyolefin in this solution or emulsion, the type of solvent, temperature, pressure conditions, etc., the fibrous material once obtained can be beaten in the same manner as wood pulp. By this, the length and surface area of the polyolefin fibrous material can be adjusted. The fibers preferably used in the method of the present invention have a length of 0.5 to 4 mm and a surface area of 0.3 to 25 m 2 /g.

使用できる。 Among the polyolefin fibrous materials that can be used as the material of the present invention, among those that have been developed as synthetic pulps, those manufactured by a method in which a solution or emulsion of polyolefin under high temperature and pressure is ejected into a low pressure area. A polyolefin fibrous material having a shape very similar to that of natural wood pulp can be suitably used.

ポリオレフインに対して５重量％以下の量で使用
される。 A fibrous material made only of polyolefin has poor water dispersibility, so a polyolefin grafted with a compound having a polar group can also be used, but it is easier to mix it with a polymer having a polar group. Among these, combination use with polyvinyl alcohol is preferred. In this case, a method can be employed in which polyvinyl alcohol is added together with polyolefin into a solution or emulsion and then ejected to adhere to or mix with the polyolefin fibrous material, or a method in which the polyolefin fibrous material is treated in a polyvinyl alcohol solution. The amount of polyvinyl alcohol added is
It is used in an amount of up to 5% by weight, based on the polyolefin.
このように、ポリビニルアルコールの併用量が

りなる材層の親水性を上げることができる。 More favorable results can be obtained by using other super-aids in addition to the polyolefin fibrous material. For example, activated carbon, diatomaceous earth, glass fiber, etc. are effective for space control and to improve the decolorizing effect, while natural fibers such as linter pulp and esparto pulp are effective for space control and as reinforcing materials for the cake layer (material layer) made of polyolefin fibers. It is. The amount of these super-aids to be blended may vary depending on the purpose of use and the type of the super-aid, but generally they are used together in an amount of 75% by weight or less based on the total weight of the cake. By adding these inorganic substances and natural fibers, the hydrophilicity of the material layer made of polyolefin fibrous material can be increased.

なるので、夾雑物の吸着量も増加する。 Furthermore, activated carbon, diatomaceous earth, and the like can be added to a polyolefin solution or emulsion for forming a fibrous material, and used as a result of being fused or entangled with the polyolefin fibrous material. This method has the advantage that the specific gravity of the fibrous material can be adjusted and its hydrophilicity can also be improved. Furthermore, since the resulting polyolefin fibrous material is broken into finer particles, its surface area becomes larger, and the amount of impurities adsorbed also increases.
以上のような方法で親水性が高められると、

に、過に必要な液性の高さを低めるのに役立
ち、工業的に有利である。 When hydrophilicity is increased by the above method,
This is industrially advantageous because it facilitates the leaching of the liquid into the material layer and helps reduce the required level of liquid properties.

It is dispersed in water together with inorganic fibers, esparto pulp, etc. as a slurry, or dispersed in a filtered liquid, and introduced into a filter, for example, on a cloth in a filter press, to form a material layer, and then In this method, the liquid to be filtered is passed through this layer of material. In a typical filter press, several layers of these materials are formed and maintained, and each of these layers is utilized as a layer of liquid material.

るという利点を有する。 In the case of a method of forming a material layer in advance,
The material layer made of the polyolefin fibrous material can be heat-treated in a hot air permeation oven or in an ordinary open air condition with or without pressure, as necessary, to fuse the polyolefin fibrous material. When the material layer contains the above-mentioned super-aiding agent, this heat treatment causes interaction with inorganic substances, inorganic fibers, natural fibers, etc. existing in the vicinity of the polyolefin fibrous material.
Since the spatial position and void state can be changed, it has the advantage that the mechanical strength and over-characteristics of the material layer can be adjusted.

何らの支障をもたらす変化は見られなかつた。 When the obtained liquid was compared with the liquid obtained by using a liquid column colorimeter and a nephelometer, it was found that the liquid obtained by the present invention was more preferable as a commercial product. “Teri”
It was a clear sake with a strong flavor. Also, if this is stored for 3 to 6 months, it will become cloudy or cloudy.
The incidence of this was also relatively low. The light transmittance of the liquid by short wavelength light (430 mμ) is 99.4% immediately after passing, 98.7% after 3 months, and 98.5% after 6 months.
Therefore, no changes were observed in the taste or smell of the sake that would cause any problems as a product.
