Abstract

PURPOSE:To obtain wiping cloth for pin ball machines which has an excellent cleaning effect, does not generate cracks (crazes) in plastic of pin ball machine frames, etc., by impregnating a non-woven fabric with a surfactant consisting of citrus oil as a chief material. CONSTITUTION:The wiping cloth for pin ball machines is formed by impregnating the nonwoven fabric with the surfactant consisting of the citrus oil as the chief material. The citrus oil refers to the oil squeezed from citrus fruits, such as mandarin oranges, lemon, navel oranges, oranges, grapefruits and more particularly the wiping cloth formed by using the citrus oil squeezed from the skin of the mandarin oranges is excellent in cleaning effect and effect of preventing generation of the cracks in the plastic. The citrus oil is usually used in combination with non-ion surfactants and an inorg. salt and polyhydric alcohol are added thereto at need. Fibers having water absorbing and holding properties, for example, spun lace and fibers formed by a spun bonding process, etc., are used as the fibers excellent in strength at the time of wetting, etc., as the non-woven fabric.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiping cloth for pachinko machines.

[0002]

2. Description of the Related Art Wiping cloths for pachinko are applicable to various materials from various plastics such as glass of pachinko machines, upper plates, lower plates, pachinko balls and so-called dollar boxes containing pachinko balls, metal, glass and various materials, In addition, it is excellent in the wiping effect on pachinko peculiar to tobacco, and it is also required to have antibacterial and deodorant effects, which are strong against oil stains.

However, conventional so-called wet tissues have a poor cleaning effect because they are mainly composed of alcohols and surfactants, and are used in glass windows, toilets, baths, dishes, kitchens, etc., especially cigarette tar and oil. Although various cleaning agents for household use that are said to be resistant to dirt, such as cleansers, have a cleaning effect, they cannot be used because they cause minute cracks (cracks) in the plastic such as the pachinko machine. Wiping cloth has not been proposed yet.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wiping cloth for a pachinko machine, which has an excellent wiping effect and which does not cause cracks in plastic such as a pachinko machine.

[0005]

The present invention is a wiping cloth for pachinko, which is obtained by impregnating a non-woven fabric with a surfactant containing citrus oil as a main component. The present invention has completed a wiping cloth for pachinko for the first time by using a surfactant containing citrus oil as a main ingredient.

In the present invention, the citrus oil is squeezed from citrus fruits such as mandarin orange, lemon, navel, orange, pomelo and grapefruit, and especially citrus oil squeezed from mandarin orange peel is excellent. It is excellent in cleaning effect and prevention of cracking of plastics, which is preferable. Such citrus oil is usually used as a mixture with a nonionic surfactant, and if necessary, an inorganic salt or a polyhydric alcohol is added.

The content of citrus oil in the nonionic surfactant may be appropriately selected depending on the desired cleaning effect.
It is preferably 0.6 to 4.0% by weight, more preferably 0.8 to 3.0% by weight. If it is less than this, the wiping effect may be insufficient in practice, and if it exceeds this, a remarkable improvement of the wiping effect cannot be expected. The present invention is a non-woven fabric impregnated with a surfactant containing citrus oil as a main component,
The content in the nonwoven fabric is 150 to 250% owf, preferably 150 to 250% owf. If it is less than this, the wiping effect may be insufficient in practice, and if it exceeds this, a remarkable improvement of the wiping effect cannot be expected.

The nonwoven fabric used in the present invention is a water-absorbing or water-absorbing fiber, for example, regenerated cellulose fiber such as pulp, cotton, cupra, viscose rayon, polynosic rayon,
Single-fiber denier is made up of ultrafine fibers of 1 denier or less, one or more synthetic fibers such as polyester, polyamide, acrylic, etc. having improved water retention and water content due to atypical cross section or porosity, needle punching, bonding, Nonwoven fabrics produced by a known production method such as a spunlace method and a spunbond method are generally used, but a nonwoven fabric produced by the spunlace method and the spunbond method are particularly preferable because they have excellent wet strength and the like. In particular, a non-woven fabric made of cupra long fibers is lint-free and is preferable because it has an excellent wiping effect. In addition, a non-woven fabric having no binder is preferable from the viewpoint of compatibility with a surfactant containing citrus oil as a main component.

The basis weight of such a nonwoven fabric is 20 to 12
0 g / m ^2, preferably 30 to 80 g / m ^2, more preferably it is 30 to 60 g / m ^2. A non-woven fabric impregnated with a surfactant containing citrus oil as the main ingredient is easy to use when treated in the same way as a conventional wet tissue, and unlike household use, it is handled for commercial use,
For example, a thermoplastic resin such as a polyolefin resin may be taken out one by one from the take-out port of the upper lid by using the storage section and the upper lid formed by various molding methods. It is preferable to use an injection-molded product for both the storage portion and the upper lid, since it is not roughly handled or even if it is used for a long period of time, there is almost no scattering or evaporation of a surfactant containing citrus oil as a main component.

There are box type and bottle type container shapes, but the bottle type is preferable because it is easy to handle. Further, the volume of the container may be appropriately designed according to the number of wet tissues to be stored, and the area of the bottom surface is 0.1 in terms of handleability.
Approximately 1.0 m ² and a height of approximately 20 to 50 cm are suitable. The wet tissue may be stored in a stacked form or a so-called roll form, but a roll form is preferable.

The number of wet tissues is 250 or more (the upper limit can be appropriately selected as desired, but generally 1
It is preferable to store about 000 sheets).

[0012]

[Examples and Comparative Examples] A nonionic surfactant (trade name "Mikan Club"; Honshu) containing 0.8% by weight of citrus oil squeezed from mandarin orange in a 38 g / m ² cupra long fiber nonwoven fabric 280 sheets of wet tissue containing 180% OWF (180 mm * 300 mm /)
In a pachinko parlor using a container (a container for wet tissue and an upper lid) both made of polyethylene resin injection-molded in a cylindrical container (diameter 25 cm, height 30 cm) Was carried out.

In Comparative Example 1, a conventional ethanol-based drug was contained. In Comparative Examples 2 to 5, household kitchen detergents were used instead of citrus oil (Comparative Example 2: trade name "Super Homing"). Comparative Example 3: brand name "Magic phosphorus", Comparative Example 4: brand name "My Pet", Comparative Example 5: brand name "Kitchen Higher"; all manufactured by Kao Soap Co., Ltd.) in an amount of 0.8% by weight. The thing was used and evaluated similarly to an Example.

In the example, the wiping effect was excellent, and cracks did not occur in the plastic such as a pachinko machine, but in the comparative example 1, the wiping effect was poor and the comparative example 2
Nos. 5 to 5 had cracks in the plastic.

[0015]

According to the present invention, it is possible to provide a wiping cloth for a pachinko machine which has an excellent wiping effect and does not cause a crack (crack) in a plastic such as a pachinko machine.
