Description

The present invention relates to a cleaning tool capable of removing dirt adhering to a floor surface and wiping off the removed dirt at the same time and efficiently.

Conventionally, in order to remove dirt adhering to the floor surface or to remove dirt etc. adhering to the sash of the window frame, the floor surface is first rubbed with a brush-like object. A method of peeling off the dirt from the cloth and wiping off the dirt that has been peeled off with a cloth-like material is generally performed. In such a case, two types of cleaning tools, a brush-shaped one and a cloth-shaped one, are required. Moreover, if the floor surface is rubbed strongly with a brush-like object, the floor surface or the like is likely to be scratched.

In addition, it is necessary for the cloth-like material to reach the corner in order to wipe off the dirt accumulated in the corner, but it is difficult for the cloth-like material to reach the corner, and a sponge-like material is used instead of the cloth-like material. However, it is also difficult to wipe off the dirt that has accumulated in the corners. Furthermore, in the case of cloth-like materials and sponge-like materials, they have the disadvantages that they lose their waist in a short period of time, become less bulky, are easily worn out, and are difficult to reach the corners. Will decrease and the ability to wipe off dirt existing in the corners will also decrease.

As a cleaning tool that can wipe off dirt with such a brush, a cut pile is attached to the outer peripheral portion of the base material, and a loop pile is attached to the inner portion of the base material surrounded by the cut pile. A cleaning wiper is known (Patent Document 1). This document states that the cleaning wiper can be used to remove dust on the floor and dirt adhering to the floor at the same time and efficiently, but in reality, it is a cut pile. Since the loop pile is located in different places on the base material, there is a possibility of scratching the floor surface and sagging of the loop pile part, and since the cut pile faces the side, the floor surface The effect of scraping and removing dirt is not sufficient.

In addition, a cleaning tool that locks a cleaning cloth to a cleaning tool such as a mop with a hook-and-loop fastener has been widely adopted, and a cleaning sheet made of a non-woven sheet can be attached to and detached from a mounting portion made of a male hook-and-loop fastener. A cleaning tool attached to is known (Patent Document 2), but in this case, the hook-and-loop fastener is merely used as a mounting means, and the hook-and-loop fastener is involved in removing dirt and wiping dirt. Not done.

JP-A-2007-202966 (Claims, FIG. 3) JP-A-11-299 (Claims, paragraph 0008)

It is an object of the present invention to provide a cleaning tool capable of scraping off adhering dirt and wiping off dirt at the same time, further less damaging the floor surface and the like, and further reducing the settling of the non-woven fabric used for wiping. To do.

That is, in the present invention, the fluff layer of the fluff cloth made of the base cloth and the monofilament fluff is filled with a bulky non-woven fabric made of crimped fibers, and the fluff penetrates the bulky non-woven fabric and the surface of the non-woven fabric is covered with the nap. It is a cleaning tool characterized in that the tip portion of the cloth is exposed or easily exposed.

And preferably, it is a case where the bulky non-woven fabric is composed of a confounded state by three-dimensional crimped fibers, the height of the ridges is 2 to 5 mm, and the thickness of the bulky non-woven fabric is 60, which is the height of the ridges. ~ 110%, and the root of the monofilament fluff is woven into the base cloth, the tip of the fluff is crushed, and the central part of the cut surface is raised like a ridge. If you have.

Further, it is preferable that the diameter of the standing hair has a thickness of 0.10 to 0.25 mm and the standing hair density is 5 to 50 hairs / cm ² , and the standing hairs are paired with two adjacent standing hairs. This is a case where the curved tips have a curved shape so as to approach each other.

Further, preferably, the bulky nonwoven fabric is made of a composite fiber having a side-by-side type or an eccentric core sheath type cross-sectional shape of resins having different heat shrinkage rates.
And preferably, the density of the bulky non-woven fabric is in the range of ^{0.02 to 0.11 g / cm 3.}

In the cleaning tool of the present invention, the rising monofilament fluff layer is filled with a bulky non-woven fabric made of crimped fibers, and the fluff penetrates through the bulky non-woven fabric so that the tip of the fluff is exposed or bulky non-woven fabric on the surface of the non-woven fabric. Since the surface is easily exposed when pressed, when the floor surface or the like with dirt is rubbed with such a cleaning tool, the dirt is scraped off by the fluff made of monofilament, and the scraped dirt is scraped off. Will adhere to the bulky non-woven fabric and be removed. Since the monofilament fluff is only slightly protruding from the non-woven fabric surface, the force for scraping is dispersed on the non-woven fabric surface and is not concentrated on the tip of the monofilament fluff, and therefore the floor surface is almost always damaged. Absent.

In addition, the fluff is made of stretched monofilament fibers, and because it is oriented and crystallized, it has high strength for its thickness, and even if force is applied by scraping work, it will be cut or bent. Is less likely to be pulled out. Further, since the monofilament fluff (hereinafter, may be simply referred to as fluff) penetrates in the thickness direction of the bulky non-woven fabric, the non-woven fabric layer is not subjected to a great deal of compression, and therefore the non-woven fabric is settled. Less is.

Moreover, the fluff has a structure reinforced by a non-woven fabric, and therefore, even if a force is applied to the fluff by cleaning, the fluff is unlikely to fall or bend. The roots of the monofilament fluff are woven into the base cloth, and the fluff is formed from the base cloth. Therefore, the fluff does not easily fall down, and even if the fluff is caught during cleaning and tension is applied to the fluff, the fluff is pulled out. hard. Further, as shown in FIG. 2, when the tip of the fluff is crushed to form, for example, a substantially elliptical shape, and the central portion of the cut surface is raised like a ridge, the ridge-like point is sharpened. The part will scrape off the dirt efficiently.

Furthermore, when the main fibers of the base fabric, fluff and bulky non-woven fabric are both formed of polyester fibers, the fluff and non-woven fabric have strong resistance to fluff and non-woven fabric when they are used wet because they have high compressive elasticity even in a wet state. Demonstrates settling. When the non-woven fabric constituent fibers are composed of composite fibers having a side-by-side type or eccentric core sheath type cross-sectional shape of resins having different heat shrinkage rates, they may be three-dimensionally crimped by heating (hereinafter, referred to as microcrimps). ) Will occur, and even stronger settling resistance will be exhibited.

Further, since the microcrimp is coiled, the bulky non-woven fabric is hard to come off from the fluff when the fluff is sandwiched between the coils and fixed, and the bulky non-woven fabric hardly comes off by itself during use. Further, when the fluff has a curved shape in which two adjacent fluffs are paired and the curved tips approach each other, the non-woven fabric is prevented from coming off from the fluff and the tip of the fluff is on the floor surface. It can be prevented to hurt more highly.

It is sectional drawing which shows typically an example of the cleaning tool of this invention. It is a figure which shows enlarged and schematically the tip part of the example of the standing hair which constitutes the cleaning tool of this invention.

First, the cleaning tool of the present invention will be described in detail based on the attached drawings.
Basically, as shown in FIG. 1, the cleaning tool of the present invention is a bulky non-woven fabric made of crimped fibers on a fluff layer of a fluff cloth made of a base cloth (1) and monofilament fluff (2) rising from the surface thereof. It has a structure filled with 3), and the fluff (2) penetrates through the bulky non-woven fabric (3) so that the tip of the fluff is exposed or easily exposed on the surface of the non-woven fabric. ing. The support (5) may be integrated on the back surface side of the base cloth (1) via the adhesive layer (4).

The base cloth may be a woven fabric, a knitted fabric, or a non-woven fabric, but a woven fabric is preferable because its shape does not easily collapse even if it is handled roughly. In the case of a woven fabric, the warp and fluff that make up the base fabric are both yarns formed of a polyester resin, and the weft contains a core-sheath type heat-sealing polyester fiber, and the fluff is further formed. It is preferable that the heat-sealing fibers constituting the base fabric are melt-fixed in terms of settling resistance when wet, that is, morphological retention.

Rigidity and shape retention are required for naps, and synthetic fiber monofilaments are used for this purpose. In the present invention, the performance is almost the same even when wet, that is, the monofilament is excellent in water resistance. Therefore, the monofilament is composed of a polyester type, particularly preferably a polyethylene terephthalate type or a polybutylene terephthalate type, and particularly a polybutylene terephthalate type polyester. The monofilament to be used is used.

As the monofilament constituting the fluff, a monofilament having a diameter of 0.10 to 0.25 mm is preferable, and a monofilament having a diameter of 0.15 to 0.20 mm is more preferable. When the diameter is 0.10 mm or more, the effect of scraping dirt is high and the settling resistance is improved, and when the diameter is 0.25 mm or less, scratches are less likely to occur.

The cross-sectional shape of the fluff does not have to be circular, and may be an elliptical, flat, multi-leaf, polygonal or other irregular cross-section or a hollow cross-section. The diameter here means the diameter when converted into a circle equivalent to the cross-sectional area.

As a method for forming fluff, a method in which a loop made of monofilament is formed on the base cloth and a cut is made at the tip of the loop to make the loop into two fluffs is preferable. Prior to making a cut in the tip of the loop, the woven fabric is heated to melt the sheath component of the core-sheath type cross-sectional fiber, and the shape of the base fabric is fixed by the molten resin, and the shape of the loop is heat-fixed. It is preferable to use the method of By using such a method, the fluff whose tip is cut has a structure in which two adjacent fluffs are paired and the curved tip approaches each other, and the gripping property of the non-woven fabric is improved. Improves the ability to scrape dirt.

The height of the naps is preferably 2 to 5 mm because the non-woven fabric layer can be sufficiently filled and the dirt scraping effect is high. The height of the naps referred to here is the height from the surface of the base cloth to the tip of the naps, and is an average value of 10 arbitrarily selected naps. More preferably, the nap height is 2 to 4.5 mm.

Then, as shown in FIG. 2, the tip of the fluff is crushed to form, for example, a substantially elliptical shape, and the central portion of the cut surface is raised like a ridge (2-2). ) It is preferable to have a shape, and this ridge-shaped pointed portion enhances the effect of stripping dirt. In order to make the cut surface have such a cross-sectional shape, it can be easily obtained by compressing the tip of the loop from both sides with a clipper or the like and cutting. Of course, not all of the cut surfaces need to have such a ridge-like cross-sectional shape, but most of them preferably have such a shape.

It is preferable that the tip of the fluff remains in a state in which the monofilament is cut in a state of facing away from the base cloth. The peeling effect is effective when it is hook-shaped and close to the base cloth surface like the male material of the conventional hook-and-loop fastener, or when the tip is heated and melted to form a mushroom-shaped bulging head. It will be insufficient.

In the present invention, the density of naps is preferably 5 to 50 / cm ² in terms of ease of insertion into a non-woven fabric, dirt scraping effect, settling resistance, and the like. Particularly preferably, it is in the range of ^{10 to 40 lines / cm 2.} Then, it is preferable that the monofilament for fluffing is woven into the base cloth in parallel with the warp at a ratio of 1 in 12 warp.

Further, in the present invention, in order to prevent the naps from falling over, a nap loop is formed across three or more warp threads, and particularly preferably, a loop is formed across six or more warp threads. is there. The upper limit of the number of straddles is not particularly limited, but 10 or less is preferable in terms of production. In this way, by straddling a large number of warp threads, the foot of the loop is widened, and it becomes easy to continuously cut the tip of the loop.

Further, the warp yarn is a multifilament yarn made of polyethylene terephthalate, and the weft yarn is a core-sheath type polyester having a low melting point and a polyester having a high melting point as the core component, for example, a copolymerization component for lowering the melting point. A multifilament yarn made of a polyester-based core-sheath type fiber made of a polyethylene terephthalate homopolymer in which the core component is substantially not copolymerized is used.

As the warp and weft, a multifilament yarn having a thickness of 100 to 400 dtex / 10 to 96 filaments manufactured from a polyester resin is preferably used. The weaving density is preferably 50 to 60 warp threads / cm and 10 to 25 weft threads / cm. Plain weave is generally used as the weave structure. The basis weight of the base cloth is preferably ^{200 to 300 g / cm 2.}

When the woven fabric constituent fibers are fixed by the core-sheath type heat-sealing fibers described above, the warp, weft and fluffing monofilaments are all composed of the same type of polymer due to the adhesive force of the fluffing monofilaments. It is preferable to prevent the base cloth from falling over, and specifically, it is preferably composed of a polyester-based polymer.

It is also possible to add an antibacterial agent to the base cloth and fluff that make up the cleaning tool of the present invention in order to prevent germs from propagating, and further, apply an antibacterial agent to the fibers and fluff monofilaments that make up the base cloth. It is also possible to knead.

Next, a bulky nonwoven fabric (3) made of the other material constituting the present invention will be described.
It is preferable that the non-woven fabric is bulky and has a density in a specific range in order to penetrate the naps. It is difficult to use a non-woven fabric in which fibers are oriented in the thickness direction of the non-woven fabric to densify the structure in the present invention.

Specifically, a non-woven fabric in which the density of the non-woven fabric is suppressed in the range of ^{0.02 to 0.11 g / cm 3 is used.} More preferably, it is in the range of ^{0.03 to 0.08 g / cm 3.} Then, it is preferable that the fibers constituting the non-woven fabric are oriented in the surface direction of the non-woven fabric and not substantially oriented in the thickness direction of the non-woven fabric. For that purpose, it is preferable that the fiber webs are not entangled in the thickness direction but are heat-treated to develop three-dimensional crimping of the constituent fibers, and the three-dimensional crimping that is expressed is preferably coiled in the non-woven fabric surface direction. The shape is maintained by expressing the confounding of. Since the coil crimp fibers are oriented in the direction of the surface of the non-woven fabric, the fluff is sandwiched between the coils, and the non-woven fabric is difficult to easily come off from the fluff.

More specifically, a method is used in which a web obtained by the curd method from staple fibers that develop three-dimensional crimps by heating is first heated in the next step to develop three-dimensional crimps. A small portion of the fibers of the fiber web may be lightly entangled for the purpose of preventing the fibers from scattering in the subsequent heat crimp development treatment. Specifically, a method is used in which water at a low temperature and low pressure at which three-dimensional crimp does not occur is sprayed to bring the fiber web into a wet state, and then heated in the next step to develop three-dimensional crimp.

As the injection of low-temperature low-pressure water, it is preferable to use water having a low pressure such that the entire web is wet and a water temperature of about 10 to 40 ° C. This treatment is different from the treatment method in which the fibers are firmly entangled in the thickness direction by a high-pressure water flow to dramatically increase the web strength, as is performed with a water-flow entangled non-woven fabric, and the fibers are simply scattered by wetting. It is a light process that suppresses this.

Then, as the heat crimp expression treatment to be performed next, dry heat treatment may be performed, but since it is difficult to uniformly develop crimps even inside the non-woven fabric, a method of treating with high temperature steam is preferable. As a method of treating with high-temperature steam, specifically, a method of subjecting a fiber web treated with low-temperature water to high-temperature steam treatment with a conveyor belt is used. The fiber web shrinks significantly due to high temperature steam treatment. Therefore, it is preferable to overfeed the supplied fiber web for high temperature steam treatment. The overfeed ratio is preferably 110 to 250% with respect to the length of the target non-woven fabric.

When the heat treatment with high-temperature steam is performed, the heated steam permeates into the inside of the fiber web, and coil-shaped three-dimensional crimping is uniformly developed from the front surface to the back surface. On the other hand, in the case of dry heat treatment, there is a problem that only the front surface of the fiber web is intensively heated to develop crimping, while the inside and the back surface side of the fiber web are not sufficiently crimped. There is.

In the high temperature steam injection, high temperature steam is injected from an orifice having a diameter of 0.2 to 0.5 mm arranged at intervals of 1 to 2.5 mm in the width direction of the supplied fiber web. The pressure of the high-temperature steam is preferably 0.2 to 1.5 MPa and a temperature of 80 to 120 ° C.

As the crimp-developing fiber, a composite fiber having a side-by-side type or an eccentric core sheath type cross-sectional shape of polyester resins having different heat shrinkage rates can be mentioned as a preferable example. Of course, a blend of such a composite fiber and another fiber may be used. A preferable combination of polyester resins having different shrinkage rates is a combination in which one resin is polyethylene terephthalate homopolymer and the other resin is polyethylene terephthalate copolymerized with isophthalic acid, sodium sulfoisophthalate, diethylene glycol, butanediol, etc. Is listed as.

The average fineness of such a composite fiber is preferably 1 to 5 dtex, particularly 1.5 to 4 dtex. If it is too thin, it is difficult to develop a beautiful three-dimensional crimp, and if it is too thick, the fibers become rigid, and it is also difficult to develop a beautiful three-dimensional crimp. Further, the average fiber length of the composite fiber is preferably 20 to 70 mm, particularly preferably 30 to 60 mm. If the fibers are too short, the entanglement between the fibers will be insufficient, and it will be difficult to obtain strength and elasticity. On the contrary, if the fibers are too long, it will be difficult to form a fiber web with a uniform texture, and the fibers will be crimped. When the fibers are expressed, the fibers interfere with each other to prevent the development of a beautiful coil-shaped three-dimensional crimp (hereinafter, also referred to as coil crimp).

In order to make the fibers web, it is necessary that the fibers have a crimp of about 5 to 15 fibers / 25 mm, but in the present invention, at such a level of crimping, the crimping resistance is low and the resistance is low. A bulky non-woven fabric having excellent sagging property cannot be obtained, and therefore, it is insufficient for the cleaning tool used in the present invention. Therefore, it is preferable to develop coil crimping of about 25 to 120 pieces / 25 mm by heating, and more preferably about 25 to 50 pieces / 25 mm.

The average radius of curvature of the circle of the developed coil crimp is preferably 50 to 200 μm, and the average pitch of the coil is preferably 0.03 to 0.3 mm. Then, such coil crimping makes it difficult for the standing hair penetrating the non-woven fabric to come off. That is, the fluff is sandwiched between the spirals of the coil to prevent it from coming off, and the non-woven fabric is prevented from sagging. The presence of the coil parallel to the surface direction of the non-woven fabric resists the compression of the non-woven fabric and keeps the bulkiness forever.

The thickness of the obtained non-woven fabric is preferably 60 to 110% of the nap height, specifically 1.2 to 5.5 mm in thickness, particularly 2.5 to 4.5 mm. If a sufficient thickness cannot be obtained with one non-woven fabric, it is possible to stack a plurality of non-woven fabrics to obtain the above thickness. However, when they are used in layers, the non-woven fabric on the upper part may be easily peeled off and difficult to use. Therefore, it is preferable that one non-woven fabric has the above thickness.

The thickness and density of the non-woven fabric were measured according to JIS L1913 "general short fiber non-woven fabric test method (method A)", and this value was measured according to JIS L1913 "general short fiber non-woven fabric test method". The density was measured from.

An antibacterial agent can be added to the non-woven fabric thus obtained in order to prevent germs from propagating, and further, the antibacterial agent can be kneaded into the fibers constituting the non-woven fabric.

When the above-mentioned bulky non-woven fabric is superposed on the fluffy surface of the fabric having fluff obtained by the above method and lightly pressed, the fluff penetrates the non-woven fabric layer, and the non-woven fabric is filled in the fluff layer. The crimped fibers constituting the non-woven fabric are coil-crimped, and the coil crimped fibers are oriented parallel to the surface of the non-woven fabric, so that the fluff is caught between the coils and the non-woven fabric is difficult to easily come off from the fluff. It will be. Therefore, even if it is used as a cleaning tool, the non-woven fabric layer can maintain its thickness forever and prevent it from sagging for a long period of time.

In the cleaning tool thus obtained, the fluff needs to penetrate through the bulky non-woven fabric so that the tip of the fluff is exposed or easily exposed on the surface of the non-woven fabric. If the fluff is stopped in the middle of the non-woven fabric layer or stays on the back surface of the non-woven fabric, a sufficient dirt scraping effect cannot be obtained. Such a state in which the tip portion of the fluff is exposed or easily exposed on the surface of the non-woven fabric by penetrating the inside of the bulky non-woven fabric further satisfies the state of the bulky non-woven fabric by the state of the fluff as described above. By doing so, it is easily achieved.

As shown in FIG. 1, the cleaning tool of the present invention can have a support (5) attached to the back surface of the base cloth (1) via an adhesive (4). For example, as a cleaning tool used for home use, a gripping rod can be attached to the support (5). Further, as an electric cleaning tool, a hook-and-loop fastener can be attached to the back surface of the base cloth of the fluffy cloth, and both hook-and-loop fasteners can be engaged with the support board to which the other hook-and-loop fastener is attached to be fixed and used.

The cleaning tool is moistened with water containing a detergent or a chemical, and the surface of the object to be cleaned is rubbed with the cleaning tool of the present invention. The scraped dirt is retained by the non-woven fabric and removed from the surface of the object to be cleaned.

Hereinafter, the present invention will be described with reference to Examples.
Example 1
[Manufacturing of standing woolen fabric]
Using the following warp, weft, and monofilament for fluff, a fluff cloth was manufactured by the following manufacturing method.
[Warp] Polyethylene terephthalate multifilament yarn composed of 167 dtex / 48 filaments [Weft] 198 dtex / 96 filament with a core-sheath composite cross section in which the sheath component is 20 mol% isophthalic acid copolymerized polyethylene terephthalate and the core component is polyethylene terephthalate homopolymer. Multifilament yarn [monofilament for fluff] 320dtex (0.17mm in diameter) polybutylene terephthalate monofilament

[Production method]
Warp density: 140 threads / inch Weft density: 48 threads / inch The monofilament for nap was driven in parallel with the warp threads at a ratio of 1 in 12 warp threads.
Weave structure: Plain weave

Weaving method of fluffy monofilament: The fluffy monofilament sinks and floats alternately under and above 5 weft threads, and then protrudes as a loop on the surface of the base fabric, skipping 6 warp threads and 1 weft thread to the other side of the loop. The legs of the fabric sank into the base fabric, and in that state, the bottom and top of the five weft yarns sank alternately in parallel with the warp yarns, and then protruded again as a loop on the surface of the base fabric, with six warp yarns and one weft yarn. Repeat skipping and returning to the original warp.

The loop cloth obtained by the above method was heat-treated at a temperature of 190 ° C. for 1 minute, and then the center of the tip of the loop formed by the fluffing monofilament was cut so as to be crushed with a clipper to prepare a fluffy cloth. The fluff monofilament is sufficiently fixed to the base fabric by shrinkage and fusion of the weft threads. As a result, two adjacent fluffs (that is, the two fluffs generated by cutting the tip of one loop) are paired, and the curved tip is curved so as to approach each other. Had. When the tip of the fluff was magnified and observed, as shown in FIG. 2, most of the tips of the fluff were crushed, and the shape was substantially elliptical and the central part of the cut surface was raised like a ridge. Was.

[Manufacturing of bulky non-woven fabric]
Side-by-side composed of a polyethylene terephthalate resin (component A) having an intrinsic viscosity of 0.65 and a modified polyethylene terephthalate resin (component B) in which 20 mol% of isophthalic acid and 5 mol% of diethylene glycol are copolymerized as latent crimp fibers. Mold composite staple fiber (“PN-780” manufactured by Kuraray Co., Ltd., 1.7 dtex × 51 mm length, mechanical crimp number 12 pieces / 25 mm, coil crimp number 62 pieces / 25 mm after heat treatment at 130 ° C. × 1 minute) Got ready.

Using 100% by mass of this side-by-side composite staple fiber, a parallel card was used to obtain a card web ^{of 35.3 g / m 2.}

Then, while transferring this card web by a belt conveyor, the web is wetted with a small amount of water and lightly entangled, and then the web is introduced into the steam injection device, and 0.5 MPa of steam is perpendicular to the web from this steam injection device. Was treated with steam to develop coil-like three-dimensional crimping of latent crimped fibers.

The hole diameter of the steam injection nozzle was 0.3 mm, and an apparatus was used in which the nozzles were arranged in a row at a pitch of 2 mm along the width direction of the conveyor. The overfeed during the steam treatment was set to about 210%, and the processing speed was 10 m / min.

The obtained non-woven fabric had a basis weight of 75.5 g / m ² , a thickness of 1.21 mm, and a density of 0.06 g / cm ³ . This non-woven fabric was bulky and had cushioning properties.

The surface of the obtained non-woven fabric was photographed with an electron microscope (100 times). Further, the cross section in the thickness direction was photographed with an electron microscope (100 times). As a result, in the obtained non-woven fabric, each fiber is uniformly crimped in a substantially coil shape in the thickness direction (the number of coil crimps is 29 / the average pitch of 25 mm coils is 126 μm), and the non-woven fabric is obtained with respect to the surface direction of the non-woven fabric. It was observed that the coils were oriented while appearing substantially in parallel.

The bulky non-woven fabric was superposed on the fluffy surface of the fluffy cloth obtained by the above method and lightly pressed. As a result, the fluff penetrated the non-woven fabric layer, and the tip portion thereof was slightly exposed on the surface of the non-woven fabric. As shown in FIG. 1, a plastic support portion is attached to the back surface side of the fabric having fluff, and a gripping rod is attached to the end portion of the support portion so that it can be held by hand to complete the cleaning tool. It was.

When such a cleaning tool was soaked in warm water containing kitchen detergent and lightly rubbed the slimy area in the kitchen sink, the slime was easily removed and the bright metallic color of the sink was restored. .. Similarly, when the tile surface on the back surface of the gas stove was rubbed with the same cleaning tool soaked in detergent water to remove the adhering dirt, the dirt could be completely removed by rubbing lightly.

Furthermore, when the PVC wallpaper surface on the wall surface of the kitchen was lightly rubbed, the stains that had adhered over the years and the stains that had adhered due to the embossment of the PVC plasticizer could be removed extremely easily. Furthermore, when the cleaning tool was used with the detergent water soaked and rubbed to remove dirt and mold adhering to the groove of the aluminum sash, it could be easily removed and the removed dirt and mold were also adsorbed by the non-woven fabric. I was able to remove it. Moreover, in each case, the sink surface, tile surface, wallpaper, and aluminum sash were not damaged at all.
In addition, the non-woven fabric did not peel off from the raised fabric during the work, and even after use, the non-woven fabric had the initial thickness and waist, and there was no feeling of being worn out. Furthermore, as a result of peeling off the non-woven fabric and observing the state of the fluffy cloth, the appearance was the same as before use.

Example 2
In Example 1 above, the fluffy monofilament was replaced with a monofilament yarn made of polybutylene terephthalate of 360 dtex (diameter 0.18 mm), and the fluff height was changed to 3.4 mm.
Further, the non-woven fabric used is a side-by-side type composite staple fiber (“PN-780” manufactured by Kuraray Co., Ltd., 1.7 dtex × 51 mm length, mechanical crimp number 12 pieces / 25 mm, which was used as the latent crimp fiber in Example 1 above. , 130 ° C x 1 minute heat treatment with 62 crimps / 25 mm), as a moist heat-adhesive fiber, the core component is polyethylene terephthalate, and the sheath component is an ethylene-vinyl alcohol copolymer (ethylene content 44 mol%, saponification). A core-sheath type composite staple fiber (“Sofista” manufactured by Kuraray Co., Ltd., 3.3 dtex × 51 mm length) having a degree of 98.4 mol%) was prepared. Side-by-side composite staple fibers / moist heat-adhesive fibers = 70/30 ratio (mass ratio) was mixed approximately uniformly, and a parallel card was used to obtain a card web ^{of 106.1 g / m 2.}
Then, the web was introduced into the steam injection device without entanglement treatment, and 0.5 MPa of steam was ejected perpendicularly to the web from this steam injection device to perform steam treatment, and coiled winding of latent crimped fibers. The shrinkage (28 coil crimps / average pitch of 25 mm coil 131 μm) was exhibited, and the bonding points between the fibers were formed by the moist heat adhesive fibers.
The hole diameter of the steam injection nozzle was 0.3 mm, and an apparatus was used in which the nozzles were arranged in a row at a pitch of 2 mm along the width direction of the conveyor. The overfeed during the steam treatment was set to about 110%, and the processing speed was 10 m / min.
The obtained non-woven fabric had a basis weight of 122 g / m ² , a thickness of 3.75 mm, and a density of 0.03 g / cm ³ . This non-woven fabric was bulky and had cushioning properties.

A cleaning tool was prepared by using the above-mentioned non-woven fabric in the same manner as in Example 1.
When the obtained cleaning tool was used for cleaning the kitchen wallpaper in the same manner as in Example 1 above, it was extremely excellent in cleaning power as in Example 1 and was further cleaned during cleaning. The non-woven fabric did not peel off from the fluff, the non-woven fabric did not sag when used as a cleaning tool, and neither the fluff cloth nor the fluff was bent.

Example 3
In Example 1 above, the fluffy monofilament was replaced with a monofilament yarn made of polybutylene terephthalate of 360 dtex (diameter 0.18 mm), and the fluff height was changed to 3.4 mm.
A cleaning tool was produced in the same manner as in Example 1 by making the three-dimensional crimped non-woven fabric produced in Example 1 exactly the same except that two layers were stacked.
When the obtained cleaning tool was used for cleaning the kitchen wallpaper in the same manner as in Example 1 above, it was extremely excellent in cleaning power as in Example 1 and was further cleaned during cleaning. The non-woven fabric located at the top of the two non-woven fabrics does not come off from the standing hair, the non-woven fabric does not sag when used as a cleaning tool, and the standing wool cloth and the standing hair do not bend. It was.

Comparative Example 1
Similar to Example 1, side-by-side composite staple fiber (“PN-780” manufactured by Kuraray Co., Ltd., 1.7 dtex × 51 mm length, mechanical crimp number 12/25 mm, crimp after heat treatment at 130 ° C. × 1 minute Number 62 pieces / 25 mm) was prepared.
Using 100% by mass of this side-by-side type composite staple fiber, a card web ^{of 75.0 g / m 2 was prepared by a semi-random card.}
Then, while transferring this card web by a belt conveyor, the web is wetted with a small amount of water and lightly entangled, and then nozzles with a diameter of 0.1 mm are provided in a row at intervals of 0.6 mm in the width direction of the web. Water was sprayed from the nozzle and the fibers were entangled using two stages at a time. The water pressure was sprayed at 4 MPa on both the front and back surfaces of the nozzle row in the front stage, and at 7 MPa on both the front and back surfaces in the nozzle row in the rear stage.
After that, a web was introduced into a steam injection device, and 0.5 MPa of steam was ejected perpendicularly to the web from this steam injection device to perform steam treatment to develop coiled crimp of latent crimp fibers. .. The latent crimped fiber had a highly entangled structure, and the number of coil crimps and the average pitch of the coils could not be measured.
The hole diameter of the steam injection nozzle was 0.3 mm, and an apparatus was used in which the nozzles were arranged in a row at a pitch of 2 mm along the width direction of the conveyor. The processing speed was 10 m / min without overfeeding during the steam treatment.
The obtained non-woven fabric had a ^{grain size of 75.0 g / m 2} , a thickness of 0.46 mm, and a density of 0.16 g / cm ³ , and the non-woven fabric constituent fibers were oriented in the non-woven fabric thickness direction.
When this non-woven fabric was superposed on the fluff cloth used in Example 2 and pressed so that the fluff penetrated the non-woven fabric, the fluff could hardly penetrate due to the entanglement of the fibers constituting the non-woven fabric. The tip was far from being exposed, and both were bent on the back surface of the non-woven fabric, and the non-woven fabric could not be overlapped and integrated with the standing woolen cloth.

Comparative Example 2
Similar to Example 1, side-by-side composite staple fiber (“PN-780” manufactured by Kuraray Co., Ltd., 1.7 dtex × 51 mm length, mechanical crimp number 12/25 mm, crimp after heat treatment at 130 ° C. × 1 minute Number 62 pieces / 25 mm) was prepared.
Using 100% by mass of this side-by-side type composite staple fiber, a web of 250 g / m ^{2 was obtained} by a cross web of a parallel card, and the web was entangled from both sides of the web by a known needle punch method. The latent crimped fiber had a highly entangled structure, and the number of coil crimps and the average pitch of the coils could not be measured.
The obtained non-woven fabric had a basis weight of 250 g / m ² , a thickness of 2.1 mm, and a density of 0.12 g / cm ³ , and the non-woven fabric constituent fibers were oriented in the non-woven fabric thickness direction.
When this non-woven fabric was superposed on the fluff cloth used in Example 2 and pressed so that the fluff penetrated the non-woven fabric, the fluff could hardly penetrate due to the entanglement of the fibers constituting the non-woven fabric. The tip was far from being exposed, and both were bent on the back surface of the non-woven fabric, and the non-woven fabric could not be overlapped and integrated with the standing woolen cloth.

Comparative Example 3
In the first embodiment, the obtained bulky non-woven fabric was independently impregnated with warm water containing a detergent in the same manner as in the first embodiment without being superposed on the standing woolen cloth, and used as a cleaning tool for cleaning the aluminum sash. The bulky non-woven fabric could not reach the depths of the corners, which was almost the same as the conventional cleaning using a rag, and the cleaning of the five windows caused the non-woven fabric to settle and became less bulky.

The cleaning tool of the present invention is suitable for cleaning the floor surface, cleaning the wall surface, removing dirt adhering to the window frame, for example, removing dirt accumulated on the window frame of the aluminum sash.
