Abstract

PROBLEM TO BE SOLVED: To remove scale without corrosion or damage to a surface to be washed by using a fiber product having a cleaning surface mainly composed of an alumina long fiber. SOLUTION: The alumina long fiber to be used is produced by the precursor fiberization of a continuous filament obtained by spanning a highly viscous raw material consisting of a water-soluble metal compound such as aluminum oxychloride or a polyaluminoxane and silica or other additives thereto and, particularly, it preferably has a circular fiber cross section. When a cleaning is performed by use of a cleaner using such an alumina long fiber, the surface to be washed is never damaged since the cross-sectional form of the alumina long fiber is circular, and the scale that was not removable in the past can be easily removed. Particularly, composite dirt of oil and composite dirt of rust can be easily removed. Since no abrasive grain is used, the washing of the abrasive is not required. Further, since its accumulation is also eliminated, a piping is never clogged.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaner, and more particularly to a cleaner capable of removing scales (high-hard dirt) which are difficult to remove with a normal cleaning agent.

[0002]

2. Description of the Related Art At present, as dirt difficult to remove in a house,
Scales attached to places around the water may be mentioned. In the conventional technology, the scale attached to the stainless steel in the kitchen is made up of a chemical such as hydrochloric acid, a resin sheet to which abrasive particles (alumina) are attached,
Composite sheet of aluminum hydroxide and aluminum oxide,
Alternatively, removal of water stains is addressed by an operation such as rubbing using a sponge to which abrasive particles have adhered. However, although it can be removed to some extent from surfaces such as stainless steel and pottery, at present, it is not at a satisfactory level because the surface to be cleaned is corroded or damaged.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and provides a cleaner (or cleaning article) capable of removing water scale without corroding or damaging a surface to be cleaned. The purpose is to:

[0004]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies on various materials that are effective in removing scale, and as a result, it has been found that alumina-based long fibers, which are continuous long fibers, have a circular cross section. The present invention was found to be extremely effective in removing scale without damaging the surface to be cleaned, and completed the present invention. That is, the present invention is a cleaner characterized in that a fiber product mainly composed of alumina-based long fibers is used for a cleaning surface. In particular, it is preferable that the above-mentioned fiber product made of alumina-based long fibers is fixed to a support.

[0005]

Embodiments of the present invention will be described below in detail. As the alumina-based long fiber used in the present invention, a high-viscosity raw material obtained by mixing silica or other additives with a water-soluble metal compound such as aluminum oxychloride or polyaluminoxane is spun to form a precursor fiber comprising a continuous filament. It is required that the fiber cross section be circular.

In general, alumina fibers are produced by a melt fiberization method or a precursor fiberization method. The melt fiberization method is an average fiber diameter of 2-3μ by the blowing method using compressed air.
m, a short fiber having a maximum length of about 250 mm, and a non-circular fiber cross section, which is not preferable in the present invention. On the other hand, in the precursor fiberization method, a high-viscosity spinning stock solution is spun by a dry spinning method to obtain a continuous alumina precursor fiber, which is woven directly or after weaving into a plain weave structure, and then 1000 to 1300 fibers.
Heat treatment to ℃ (for example, JP-B-60-52205, JP-B-60-52205)
The cross section of the fiber is circular and retains a high-strength soft feel.

The alumina-based long fiber used in the present invention is an alumina-based long fiber obtained by the latter method of forming a precursor fiber, and particularly, a woven or non-woven fabric, a knit, a cloth, a pile, a string, or the like. It can be used in textile products in the form.
Here, particularly preferred alumina-based long fibers have a circular cross section and a fiber diameter of 5 to 20 μm, preferably 10 μm.
be of longitudinal m, and that the rear steel cord twisting at an appropriate twist number, a basis weight of 100 to 1000 g / m ^2, preferably 200 to 600 g / m ² (in particular 280 g / m ² front and back) Woven or non-woven fabrics are preferred.

The alumina-based long-fiber product of the present invention may optionally contain other natural or chemical fibers, synthetic fibers, metal fibers, glass fibers and the like. In particular, a mixture of stainless steel fibers which are metal fibers is preferable. As the weaving method of the fiber, a plain weave and a twill weave are mainly used. Specifically, plain weave and double twill are good. The density of this fiber is 8 to 45 for the warp (book / 25 mm) and the weft (book / 25 m).
In m), 8-35 is preferred because of good productivity. Further, other metals (stainless steel, glass, chromium, iron, copper, zinc, titanium, and steel) can be contained in the alumina-based long fibers. There is no limitation as long as it is a fiber that improves the elasticity and strength of the alumina fiber.

In addition, by using a binder between fibers (a polymer binder is particularly preferable), or by blending a thermoplastic fiber or the like and heating, the fibers can be joined to increase the strength of the fiber product. In this case, the content of these binders and thermoplastic fibers blended in the fiber product is 2
The range of 0 to 90 wt% is good. As thermoplastic fibers,
It is made of polyolefin resin, polyester resin, polyamide resin, etc. Specifically, PE, P
P, PET, 6-nylon, 66-nylon, polybutylene terephthalate, and the like. Further, a deodorant, an antibacterial agent, or the like may be added to the above fibers as long as the effects of the present invention are not impaired.

The shape and the like of the cleaner (cleaning article) of the present invention are not particularly limited. For example, a string product, a woven fabric, a nonwoven fabric, a pile fabric, or the like made entirely of alumina-based long fibers, including a cleaning surface, or these. Is tied into a scalloped shape or any other form with a wire or the like to form a block, or mixed with a metal scalloped, or an alumina long fiber on the cleaning surface of the support,
In particular, there may be mentioned those which are embedded in the form of a woven or non-woven fabric, or which are fixed by an adhesive or fixed by surrounding with a bag. Examples of the support include a sheet or board made of various plastic materials, a foamed sheet, a sponge board, and other various molded articles.
The thickness of the fiber product is preferably about 0.1 to 1.5 mm for good usability.

When the support serving as the cleaning surface is a sheet or a board, the thickness is 1.5 to 30 mm, preferably 3 to 30 mm.
About 20 mm is preferable. Since a certain degree of flexibility is required as a cleaning article, the bending elastic modulus is particularly preferably 9800 N / cm ^{2 to} 245000 N / cm ² , particularly preferably 49000 N / cm ²
Those in the range of cm ^{2 to} 196000 N / cm ² are preferred. Examples of the material used for such a support include polyamide (6-nylon, 6,6-nylon, etc.), polypropylene, polyethylene, ionomer, polyacetal, polyester (polyethylene terephthalate, polyethylene naphthalate, etc.), polyphenylene sulfide, polyether ketone. , Polyetherester, polyethersulfone, polyetherimide, polysulfone, polyarylate and the like. Particularly preferred materials are polyamide (6-nylon, 6,6-nylon, etc.), polypropylene, and polyethylene.

In the case of cleaning using the product of the present invention, especially since the cross section of the alumina-based long fiber is circular, the surface to be cleaned is not damaged, and the conventional resin sheet to which abrasive particles are adhered. Scales that cannot be removed with a composite sheet of aluminum and aluminum oxide or a sponge to which abrasive particles have adhered can be easily removed. In particular, the product of the present invention can easily remove complex stains such as oil stains and rust stains. Furthermore, since no abrasive particles are used, there is no flushing of the abrasive, and no accumulation of the abrasive, so there is no clogging of the piping.
