Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool which can be suitably used for cleaning articles such as kitchens, bathtubs, tiles, cooking utensils, and the body.

[0002]

2. Description of the Related Art Conventionally, sponges used as cleaning tools have been made of materials such as urethane. However, the sponge has poor drainage, is not preferable for hygiene, has low abrasion properties, and has sticky dirt. It is difficult to remove strong dirt.

On the other hand, Japanese Patent Application Laid-Open No. 10-117999 discloses a scourer in which a metal flat yarn (lame yarn) is woven or knitted into a chemical fiber and woven so as to be entangled with a base fiber surface. However, there is a problem in that, although the polishing property is good, the pot or sink of the object to be cleaned is easily damaged because it contains metal fibers. In addition, in the case of a cleaning tool made of a nonwoven cloth containing an abrasive, the polishing property is good, but when processing a large amount of dirt such as sticking of stew, the dirt accumulates on the polished surface immediately. As the abrasion is reduced, cleaning is performed to remove dirt while cleaning the non-woven cloth frequently, there is a problem in that the cleaning efficiency is poor, and the strength of the non-woven cloth itself is low, and it is used several times. There is a problem in that the surface becomes fuzzy or small pieces are torn off. Furthermore, scourers made of steel wool and stainless steel curl kate have good polishing properties, but are hard, so that the body to be cleaned is easily damaged,
Further, there is a problem in that dirt that has entered the gap is very difficult to remove. In addition, nylon towels have good lathering and relatively good drainage, but have a small slime effect, poor rinsing properties, and are difficult to remove soap without good sooting. There is a problem in that the fibers tend to fray when they are stacked.

On the other hand, a cleaning tool in which soap is encapsulated in various nets or sponges has an effect of improving foaming. However, the former in which soap is encapsulated in various nets has no abrasive power in the net itself, and thus has a cleaning effect. In addition, sponges containing urethane or the like containing soap do not have good water drainage.

Japanese Patent Application Laid-Open No. 52-47011 discloses a soap wrapped in a resin net,
No. 2 discloses a solid soap containing a shrinkable net made of a shrinkable net bag and a solid soap put in the shrinkable net bag in which the entire shrinkable net bag shrinks according to the size of the solid soap. In the first place, the use of soap prevents slippage when used, and although foaming is somewhat good, there is a problem in that there is no cleaning power (polishing power) in place of a brush.
Further, Japanese Utility Model Laid-Open No. 7-39682 discloses a razor,
Japanese Utility Model Application Laid-Open No. 63-175992 discloses sponge scourers incorporating a solid soap. The technology disclosed in these publications can improve the foaming and save the trouble of attaching the soap to the sponge. There is a problem in that it is inferior to cleaning and dirt removal.

[0006]

As shown in FIGS. 1 (a) to 1 (c), the cleaning tool of this embodiment has a sheet body 10 as a base cloth and has loop-like fiber yarns 20, 20 on one or both sides of the sheet body 10. The number of the loop-shaped fiber yarns 20, 20,... Is 5 to 50 (pieces / cm ² ), and part or all of the loop-shaped fiber yarns 20, 20,. It is characterized by the following.

In the present invention, the sheet 10 serving as a base cloth
At least one selected from natural fibers, synthetic fibers, semi-synthetic fibers, regenerated fibers (chemical fibers excluding metal fibers) or composite fibers obtained by combining these fibers, and coated fibers obtained by coating these fibers with a resin. What comprises the thing which woven or knitted the fiber is mentioned. Examples of natural fibers include cotton, wool, hemp, and the like. Examples of synthetic fibers include polyester fibers such as polyethylene terephthalate and polypropylene terephthalate, polyamide fibers such as nylon 6, nylon 66, and nylon 46, and aramid. Fiber, polyacrylonitrile fiber,
Polyolefin-based fibers such as polyethylene and polypropylene, polyvinyl alcohol-based fibers, polyurethane-based fibers, and the like. Semi-synthetic fibers include, for example, acetate-based fibers, triacetate-based fibers, and promix fibers. Examples of the chemical fibers other than fibers include rayon, polynosic, cupra, and the like. Further, the conjugate fiber in the present invention refers to a conjugate fiber obtained by compounding the above various fibers, and the coated fiber refers to a fiber obtained by coating the above various fibers (including the conjugate fiber) with a resin.

Preferred examples of the sheet include those which are slightly hydrophilic in view of the need for a certain amount of water and also have good drainage properties. Examples thereof include polyamides such as nylon and polyvinylon alcohol such as vinylon. , Acrylic, polyurethane, and acetate fibers are preferable.Also, polyester fibers or fibers composed of polyester fibers and hydrophilic rayon, cupra, or the like may be used. Good. The basis weight of the sheet body serving as the base fabric is 30 (g / m2).
² ) to 300 (g / m ² ), preferably 50 (g / m ² ).
m ² ) to 200 (g / m ² ) are desirable. When the grammage is less than 30 (g / m ² ), the base fabric has no tension,
If it is difficult to use as a cleaning tool, and if the basis weight exceeds 300 (g / m ² ), the flexibility will be reduced and drainage will be poor.

[0011] The structure of the sheet is not particularly limited, and may be an appropriate structure according to the use of the cleaning tool, for example, kitchen, bathtub, floor, body, and the like. For example, considering foaming and running out of water, FIG.
As shown in FIG. 3A, a cleaning tool that includes a large number of openings (voids) 12 regularly or randomly between the base cloth portions 11 and 11 and that includes a solid soap described later (FIG. 3) For example, a knitted or woven fabric having no opening is preferably used. Also, the shape of the sheet body,
It is not particularly limited, and depending on the use of the cleaning tool, for example, kitchen, bathtub, floor, body, etc.
The shape may be an appropriate shape, for example, a rectangular shape such as a rectangle or a square, a triangle shape, a circular shape, or the like.

As shown in FIG. 1 (b) or (c), the sheet member 10 according to the present invention has loop-shaped fiber yarns (hereinafter simply referred to as "loops") 20, 2 on one or both sides thereof.
0, and a part or all of the fiber yarn needs to be composed of hydrophobic fibers. As the material of the loop,
It is strong enough to withstand polishing and has good drainage.
For example, a fiber composed of hydrophobic fibers such as polyamide fibers such as nylon, polyester fibers, and polyolefin fibers such as polypropylene and polyethylene can be used.

In the present embodiment, the provision of the loops 20, 20,... On one or both sides of the sheet body 10 has the effect of polishing dirt and scratching off dirt.
In addition, since a hard material such as metal is not used, the object to be cleaned is less likely to be damaged. Further, in the present invention, a mass ratio of 10% by mass (hereinafter, simply referred to as “%”) or more to a part of the fiber yarns constituting the loop, specifically, the whole of the fiber yarns constituting the loop. Preferably, at least 20%, or all (100%) of the fibers are composed of hydrophobic fibers, whereby the water drainage property can be improved. If the amount of the hydrophobic fiber of the fiber yarn constituting the loop is less than 10%, the drainage property is poor, which is not preferable.

In the present invention, as shown in FIGS. 2A and 2B, the loop height H is set to 0.5 mm to 12 mm, preferably 1.5 mm to 10 mm, and the thickness R of the loop fiber is set. 0.1 mm to 0.5 mm in diameter, preferably 0.1 mm to 0.5 mm.
It is desirable to set it to 15 mm to 0.4 mm. In the present invention, five the number T of the loop / cm ² to 50 pieces / cm ²
And preferably 7 / cm ² to
40 pieces / cm ² , more preferably 7 pieces / cm ^{2 to} 35 pieces / cm ²
cm ² is desirable. The "number of loops" refers to the total number of loops provided on one side of the sheet body, and the total number provided on both sides of the sheet body when loops are provided on both sides. The height H of the loop, the thickness R of the loop fiber, and the number of loops are determined by the use of the cleaning tool, for example,
Depending on the kitchen, bathtub, floor, body, etc., each of the above numerical ranges, that is, H: 0.5 mm to 12 m
m, R: 0.1 mm to 0.5 mm, T: 5 pieces / cm ² to
It is preferable to adjust within the range of 50 pieces / cm ² , and by setting the value within each of these ranges, it is possible to obtain foams, drainage and dirt removal (cleaning power) without further damaging the body to be cleaned. Become. Further, in the present invention, 0.5 mm to 5.0 mm and the maximum width W ₁ of the loop, preferably,
And 0.5 mm to 4.0 mm, 0.5 mm to 5.0 mm width W ₂ of the loop in the base fabric 10, preferably, 0.
It is desirable to set it to 5 mm to 4.0 mm.

If the height H of the loop is less than 0.5 mm, the foaming of the soap becomes poor, the loop is less likely to be rounded, and the sharp angle makes the body to be cleaned such as cloth damaged. When the height H exceeds 12 mm, a loop is likely to be stuck on the object to be cleaned, making it difficult to clean. The loop fiber has a diameter R of 0.1 m in diameter.
If it is less than m, the polishing power is reduced, the loop becomes sharp, and the object to be cleaned such as cloth is damaged, and if the thickness R of the loop fiber exceeds 0.5 mm in diameter, the loop becomes hard, This may damage the body to be cleaned such as cloth. Further, if the number T of loops is less than 5 / cm ² , the foaming of the soap becomes worse, and the polishing power is reduced. If the number T of loops exceeds 50 / cm ² , the number of loops increases. In addition, the bubbles are poorly removed, the dirt attached to the loop is hardly removed, and the rinsing property is also deteriorated. Further, when the maximum width W ₁ of the loop is 0.5mm below and W ₂ is less than 0.5mm, the loop becomes sharper, will damage the cleaning object, such as a fabric, also the maximum width W ₁ of the loop When 5.0 mm and W ₂ exceed 5.0 mm, the polishing power is reduced and the foaming is deteriorated, which is not preferable.

The cleaning tool A according to the above-described embodiment having the above-described configuration is obtained by forming a sheet into a desired size, folding the sheet into two pieces, folding it into four pieces, or the like, and holding it in a kitchen as it is. In such as, pots, around the range, wash or sink, etc., can be used in a suitable sponge mode to polish, the brush part of the toilet brush, floor cleaning or sponge for floor cleaning such as cushion floor,
It can be used in the form of a body washing towel. In the cleaning tool A of the present embodiment, by providing a loop made of a hydrophobic fiber yarn on one or both sides of the sheet body, the dirt is polished, and the dirt has an effect of being scraped off. For example, efficiently remove (wash) a large amount of dirt, such as sticky dirt on a pot, or hard-to-remove dirt such as scorch.
It does not use hard materials such as metal, so that objects to be washed, such as pots and sinks, are not easily damaged.Also, if the sheet is colored due to dirt, it can be bleached as it is Because it is stronger, it can be washed in a washing machine. Also,
Since the loop is partially or entirely made of a hydrophobic fiber yarn, the loop is excellent in drainage.

FIG. 3 is a front view showing another example of the embodiment of the present invention. As shown in FIG. 3, the cleaning tool B of the present embodiment is based on the cleaning tool A of the above embodiment, that is, a sheet body made of at least one of the above-described various fibers.

One or all of the fiber yarns are formed of hydrophobic fibers into a bag-like (bag) 30 in which a solid soap 40,
For example, the present invention is characterized by containing cosmetic solid soap and washing soap (solid soap for washing clothes or shoes). In addition, 50 in FIG. 3 is a binding string.

In the cleaning tool B of the present embodiment, the sheet having the above structure is formed in a bag shape. The sheet used is preferably a polyester fiber, a polyolefin fiber such as polypropylene, polyethylene, or the like. Composed of hydrophobic fibers such as vinyl chloride and vinylidene chloride, or composites of these hydrophobic fibers with polyvinylon alcohol-based fibers such as vinylon, acetate-based fibers, rayon, cupra, etc. Is mentioned. In the present embodiment, the basis weight of the sheet body serving as the base cloth is adjusted within the range of the cleaning tool A of the above-described embodiment.
(G / m ² ) to 150 are desirable.

In the cleaning tool B of the present embodiment, the material of the loop is preferably a material which has strength enough to withstand polishing, does not damage the fabric, easily lathers soap, and has good drainage. For example, a fiber made of hydrophobic fibers such as polyamide fibers such as nylon, polyester fibers, and polyolefin fibers such as polypropylene and polyethylene may be used. Further, the loop height H, the thickness R of the loop fiber, and the number T of the loops are preferably adjusted within the range of the cleaning tool A of the above-described embodiment, but in the present embodiment, the cleaning containing the soap bar is performed. More preferably, the loop height H is
1.5 mm to 7 mm, the thickness R of the loop fiber is 0.
15 mm to 0.4 mm, the number of loops T is 8 pieces / cm ² to
Desirably, the number is 40 / cm ² . In particular, Zuk
When the cleaning tool is used for athletic shoes, it is more preferable that the height H of the loop be 2 mm or more so that dust in the groove on the back surface of the shoe can be scraped out.

In the cleaning tool B of this embodiment, it is preferable to have a loop on both sides. However, the cleaning tool B may have a loop on only one side, or a sheet having a loop on only one side may have a loop on the outside. They may be stacked to face each other. In use, on both sides of the loop, the soap-side loop rubs the soap to facilitate liquefaction, and the opposite side polishes the object to be cleaned. In the case of only one side, the same effect as on both sides can be exhibited by combining the cleaning body polishing center with one side. The cleaning tool B of the present embodiment
Is not particularly limited as long as it has a structure in which the above-described sheet body is formed in a bag shape (bag body) and solid soap is contained therein, and the structure, shape and the like are not particularly limited. And the like can be made into a bag having a circular or square shape, and various binding structures such as a chuck body and a hook-and-loop fastener body can be used to bind the storage opening in addition to the binding string.

In the cleaning tool B constructed as described above, the solid soap can be applied to a cloth or the like while being liquefied by the action of the sheet member. Can be prevented. In addition, the loop serves as a brush, and can be polished while applying soap, thereby saving labor for washing. In addition, it is possible to prevent cracking of the soap by appropriate drainage and water retention.

Although the cleaning tool of the present invention is configured as described above, it is not limited to the above-described embodiment, and it goes without saying that various changes can be made within the technical idea of the present invention. Nor. For example, as shown in FIG. 5 (a), a commercially available solid soap 51 using the same type of sheet is provided substantially at the center of a sheet body 20 having a loop on one side of a base cloth.
The cleaning tool C may be provided with a pocket portion 52 having a size just enough to fit therein, and after the solid soap 52 is put in the pocket portion 52 and the opening is closed with a string 53. Then, as shown in FIG. 5 (b), the sheet body 50 can be used by folding it in three with the side having the loop 54 facing up and sealing both ends.
