To do.

The above first to tenth inventions will be further described. In the first invention, when the content of the negative ion generating substance is less than 0.3 parts by weight, it is difficult to expect a sufficient negative ion generating effect. On the other hand, if it exceeds 10.0 parts by weight, the obtained granular material becomes too hard and brittle.
In addition, since the natural negative ion generating substance is generally expensive, the manufacturing cost becomes high if it is used in a large amount. In the above-mentioned mixing ratio of the negative ion generating substance, the preferable range is 2.0 to 5.0 parts by weight.

The antistatic agent is a chemical agent which is added to the molding material or applied to the surface of the product in order to reduce the electric resistance of the surface of the resin and prevent the generation of static electricity. The antistatic method by coating tends to lose its effect by rubbing or washing with water, while the antistatic method by kneading inside can maintain the antistatic effect. Therefore, as the antistatic agent in the present invention, a method of kneading into the inside is adopted. Currently used antistatic agents include various surfactants, inorganic salts, polyhydric alcohols, metal compounds, carbons, etc. Among them, the cationic surfactants are most often used.

The classification of antistatic agents includes, for example, permanent antistatic agents, general antistatic agents, nonionic polymer-based, anionic polymer-based, cationic polymer-based, nonionic surfactant-based, anionic surfactant-based, cationic surface-active agents. There are agents, amphoteric surfactants, etc., but an antistatic agent that can suppress the charge to a low level when an antistatic agent is blended and mixed, as compared with the case where a biodegradable resin is used alone. However, it is not particularly limited.

Examples of the biodegradable resin include polyvinyl alcohol, polyvinyl alcohol / starch mixture, polylactic acid, polyalkylene succinate, polycaprolactone, polycaprolactone / starch mixture, polyester carbonate, polyamino acid, polyesteramide, polyhydroxybutyrate. Rate / valerate, chitosan, etc. may be mentioned. Of these, particularly preferred are starch-produced biodegradable resins. The above starch can be used without particular limitation as long as it is starch. Examples thereof include underground starches such as corn starch (corn starch), potato starch, sweet potato starch, and tapioca starch, unprocessed starches such as wheat flour, sago starch, rice starch, and processed starches and starch derivatives using them. In the negative ion generation experiment conducted by the present inventor, the one using corn starch seems to be preferable.

Examples of the processed starch include degradation products such as dextrin, oxidized starch and low-viscosity modified starch. Furthermore, examples of the starch derivative include starch esters such as acetic acid ester and phosphoric acid ester, positive starch, and starch ethers such as hydroxyethyl ether and hydroxypropyl ether. In the case of manufacturing the cleaning tool described in the seventh invention to the tenth invention, it is essential that the size of the particles of the granular body accommodated in the cloth bag is larger than the size of the opening of the cloth bag. When the fabric bag is formed of a flexible synthetic fiber or synthetic resin bag, the size of the mesh opening of the bag is, for example, 0.1 mm square (0.1 mm × 0.1 mm) to 8. 0 mm square (8.0
mm × 8.0 mm). Further, the ratio of the size of the granular material to the size of the mesh opening is (1.0: 0.
It is preferably in the range of 1) to (1.0: 0.7).

The shape of the particles is not particularly limited as long as it is basically a three-dimensional shape capable of preventing chipping and cracking, but generally, a spherical shape, a cylindrical shape, a cylindrical shape, a pyramidal shape or the like can be adopted. However, a sphere, a cylinder, a cone, or a cylinder is preferable in order to generate fine-textured, foam-friendly bubbles.
It is preferable that the variation in particle size of the particles of the granular material placed in the bag is small. The material of the cloth is not particularly limited as long as it can function as a cleaning tool. When the cloth bag is made of synthetic fiber, for example, polyester, polyethylene, nylon, etc. are preferable. The size of the mesh of the bag containing the particles is usually 0.1 mm or less when used for general cleaning in daily life.
It is preferably within a range of 5.0 mm square.

[0017] For cleaning tools intended for human body volume of the fabric bag may preferably be in the range of 10cm ³ ~600cm ^3. The shape of the particles may be a mixture of a plurality of shapes as long as they have a volume within a certain range.
For example, there is a case where spherical particles and cylindrical particles are mixed. The plasticizer for the biodegradable resin can be appropriately selected from known plasticizers according to the type of biodegradable resin used. Examples of the plasticizer include aliphatic polyester plasticizers and phthalate ester plasticizers. Polycaprolactone can be used as the aliphatic polyester plasticizer. Examples of the phthalate ester plasticizer include diethyl phthalate, dimethyl phthalate, dioctyl phthalate, diisononyl phthalate, and the like.

The shape and size of the granular material of the present invention can be appropriately determined in consideration of the size of the cleaning tool to be used, and the granular shape includes granular shape and pellet shape. The size of the granular material of the present invention is in the range of 1.0 to 10 mm in diameter in the case of a spherical body, and the length of one side is 1.0 to 10 in the case of a rectangular parallelepiped.
The range is mm. The granular material used in the cleaning tool of the seventh invention to the tenth invention preferably contains starch as a main component,
It is preferred that at least 70% by weight is starch. Furthermore, the granular material has a hardness that does not easily cause chipping or peeling when used for a long time as a cleaning tool,
It is required to have tenacity.

It is preferably 5% or less. The granules according to the seventh invention to the tenth invention are kneaded with starch powder, biodegradable resin and a plasticizer for biodegradable resin, negative ion generating substances such as atomized tourmaline ore, antistatic agent, and the like. It can be produced by molding the obtained kneaded product into a granular body.

In the present invention, the kneading step in producing the resin composition can be carried out as follows. The kneading conditions can be appropriately selected depending on, for example, the blending amounts of the three components of the biodegradable resin, the negative ion generating substance, and the antistatic agent, and the types of the biodegradable resin and its plasticizer. For example, when heating and kneading, 130 ° C
220 ° C, preferably 140 ° C-180 ° C, 10-
It can be done for 60 minutes. Examples of equipment used for heating and kneading include a batch type pressure kneader, a Banbury mixer, a kneader ruder, a continuous type kneader, and a twin-screw extruder.

The hot kneaded product is formed into granules while it is hot. Molding, using the batch type pressure kneader or Banbury mixer, kneader ruder or continuous kneader or twin-screw extruder used for heating and kneading as it is,
Kneading and molding can be performed continuously. For molding,
For example, a die of 1.0 to 10 mmφ is used. The kneaded product obtained by the above method can be passed through the die to obtain a granular or pellet-like granular material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the drawings. First, the resin composition according to the first embodiment of the present invention will be described. The types of raw materials specifically used in this resin composition are as follows. (Biodegradable Resin) In this example, a raw material of a natural material is used as the biodegradable resin, specifically, a biodegradable resin produced from corn starch. As a biodegradable resin using such corn starch, WONDER COR of the United States is available.
P. ) Made of Wonder Starch (registered trademark).

(Negative Ion Generating Material) Ion powder as one of the negative ion generating materials is a fine particle that generates negative ions in the surrounding space. For example, tourmaline ore is crushed to have a particle size of about 1.0 μm to 5.0 μm. The finely divided particles can be used, and further 2.0 μm to 3.
Those finely divided to about 0 μm are preferable. The tourmaline ore is preferable as a raw material for the ion powder. In addition, natural or synthetic materials that generate negative ions can be used. As natural materials that generate energy for generating negative ions in the surrounding space, monazite, bustness stone, xenotime, columpe stone, betajo stone, tantalum stone, and the like are known, and these ores can be used as appropriate. Also in tourmaline ore,
Known are lithium tourmaline, dravite tourmaline, rubellite tourmaline, pink tourmaline, and watermelon. 370 becquerels / g (gram)
The following various radioactive materials can also be included. GRANITE may be used as the granite.

(Antistatic Agent) The antistatic agent is a kneading type, and a preparation which prevents the resin from being charged is used. As the resin used for styrene-based resins such as polystyrene, ABS resin and AS resin, one of the cationic surfactants, Daspar 125B (manufactured by Miyoshi Oil & Fat Co., Ltd.) and Daspar 125BN (manufactured by Miyoshi Oil & Fats Co., Ltd.) are used. did.
The chemical name of Dasper 125B is N-hydroxyethyl-
N- [2-hydroxyalkyl] amine.

The details of the sample are as follows. (Production method of granules) The biodegradable resin, the negative ion generating substance, and the antistatic agent to be blended are mixed by a predetermined mixer, and then the granules are formed by a predetermined granulating device in a heated state. To do.

[Experiment 1] This experiment 1 is an experiment for confirming the negative ion generation effect by blending the antistatic agent. Example 1 To 100 parts by weight of 6-nylon (manufactured by Toray), 3.0 parts by weight of ion powder composed of tourmaline ore with an average particle diameter of 1.0 μm, and Dasper 125B (Miyoshi oil and fat) as an antistatic agent. (Manufactured by K.K.) was added and mixed in a mixer for about 10 minutes. The mixed sample is heated at a heating temperature of 150 using a Ruder machine.
A strand having a diameter of 2 mm to 3 mm was prepared at 0 ° C., the strand was cut into a length of 2 mm to 3 mm, and the one having a length of 2 mm to 3 mm was selected excluding irregular ones to obtain the following granules. .

Comparative Example 1 Example 1 was followed except that 1.0 part by weight of antistatic agent was not added. Comparative Example 2 Example 1 was followed except that 1.0 part by weight of a silicone resin was added instead of adding 1.0 part by weight of the antistatic agent. (Example 2) In place of 100 parts by weight of 6-nylon in Example 1, an ethylene elastomer (manufactured by Aron Kasei)
The amounts of ion powder and antistatic agent added were the same as in Example 1 except that 100 parts by weight were used. (Comparative Example 3) Example 2 was followed except that 1.0 part by weight of the antistatic agent was not added. Comparative Example 4 Example 2 was followed except that 1.0 part by weight of a silicone resin was added instead of adding 1.0 part by weight of the antistatic agent.

The structures of Examples 1 and 2 and Comparative Examples 1 to 4 are as shown in FIG. The measurement results of the ionization coefficient and the number of ions in Experiment 1 are shown in FIG. The number of ions was measured using an ion tester [Kobe Denpa Co., Ltd.]. Numerical values represent the number of ions, + means positive ions, and-means negative ions. When 6-nylon is selected as the resin material, comparing Comparative Example 1 / Comparative Example 2 containing no antistatic agent with Example 1 containing an antistatic agent, the antistatic agent is 1.0 wt. It can be seen that the number of generated negative ions can be remarkably increased by adding a small amount of a small amount. Regarding the effect of this antistatic agent, even when a styrene elastomer is selected as the resin material, comparison is made between Comparative Examples 3 and 4 containing no antistatic agent and Example 2 containing an antistatic agent. For example, it can be seen that the number of generated negative ions can be remarkably increased only by adding a very small amount of the antistatic agent of about 1.0 part by weight.

[Experiment 2] Also in the sample of Experiment 2, a granular body was produced according to the production method of Experiment 1. The specific mixing ratio in that case is as follows. In Comparative Example 5, the biodegradable resin (A) was 100 parts by weight and the ion powder was 2.0 parts by weight. As the biodegradable resin (A), Wonder Starch manufactured by Wonder Co., Ltd. was used. All the ion powders used in Experiment 2 were the same as those used in Experiment 1. In Example 3, 100 parts by weight of the biodegradable resin (A), 2.0 parts by weight of the ionic powder, and 1.0 part by weight of the antistatic agent were used. All the antistatic agents used in Experiment 2 were the same as the antistatic agents used in Experiment 1. In Comparative Example 6, EVA is 100 parts by weight, ionic powder is 2.0 parts by weight, and antistatic agent is 1.0 part by weight.

In Example 4, the biodegradable resin (A) was 70%.
Parts by weight, biodegradable resin (B) 30 parts by weight, ionic powder 2.0 parts by weight, antistatic agent 1.0 parts by weight. As the biodegradable resin (B), Wonder Star SH300 manufactured by Wonder Corporation was used. In Comparative Example 7, 80 parts by weight of the biodegradable resin (A), EV
A is 20 parts by weight, ion powder is 2.0 parts by weight, and antistatic agent is 1.5 parts by weight. In Example 5, 90 parts by weight of biodegradable resin (A), EV
A is 10 parts by weight, ion powder is 2.0 parts by weight, and antistatic agent is 2.0 parts by weight. In Example 6, 70 parts by weight of biodegradable resin (A), LD
PE (low density polyethylene) is 30 parts by weight, ionic powder is 2.0 parts by weight, and antistatic agent is 1.0 parts by weight. In addition, as LDPE, J
M-910 was used. In Example 7, 100 parts by weight of polypropylene (PP), 2.0 parts by weight of ionic powder, and 1.
0 parts by weight. As the polypropylene, J-2000GP manufactured by Idemitsu Co., Ltd. was used.

The measurement results of the ionization coefficient and the number of ions in Experiment 2 are shown in FIG. Comparing Comparative Example 5 with Example 3, it can be seen that the amount of negative ions generated can be increased by using the biodegradable resin (A) and adding a small amount of antistatic agent. Comparing Example 3 and Comparative Example 6, when the biodegradable resin is replaced by EVA, the amount of negative ions generated is significantly reduced even if the same 1 part by weight of the antistatic agent is added. At least, it can be seen that the amount of negative ions generated can be increased by using a biodegradable resin rather than EVA.

A comparison between Comparative Example 7 and Example 6 shows that
It can be expected that the amount of negative ions generated will decrease as the EVA ratio increases from 10% to 20%. Referring to Examples 4, 5 and 6, if the biodegradable resin is 70% or more and the antistatic agent is about 1%, it is possible to secure the negative ion generation amount to some extent. I understand. It can be seen that even if the polypropylene of Example 7 is used, practically sufficient negative ions can be generated if the antistatic agent is contained.
