Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber wiping material for wiping off dust and dirt on a cleaning target with a fiber non-woven sheet.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
A cleaning tool is widely used in which a non-woven sheet as a cleaning member is sandwiched and held by a non-woven sheet holding head to which a handle is connected, and a floor surface or the like is wiped in a mop-like manner.

When an ordinary non-woven sheet is used as a cleaning tool to wipe an object to be cleaned, the amount of dust wiped increases, the amount of dust approaches a saturated state, and the wiping ability decreases. When the wiping capacity deteriorates, it is necessary to replace it with another non-woven sheet for further cleaning, but in the case of the conventional non-woven sheet for cleaning, it is necessary to replace the non-woven sheet relatively often, which makes the work complicated. There was also a decrease in the efficiency of cleaning work.

In particular, in the case of a non-woven sheet covering the bottom surface of the non-woven sheet holding head, dust is intensively collected at both ends in the moving direction of the cleaning tool, that is, in the vicinity of a portion corresponding to the edge of the non-woven sheet. As a result, the cleaning efficiency tends to decrease quickly. Therefore, the non-woven sheet is forced to be replaced with another non-woven sheet without effectively utilizing the part other than the edge-corresponding part of the non-woven sheet, and the non-woven sheet is consumed quickly.

The present invention has been made in view of the above problems existing in the prior art, and an object of the present invention is to remove a large amount of dust until it reaches a saturated state. It is to provide a fiber wiping material having a large total amount that can be wiped off.

[0006]

A fibrous wiping material of the present invention which achieves the above object is a wiping material having one or more cleaning parts made of a non-woven fiber sheet, which is wholly or partly The non-woven sheet is a superposed section in which two sheets are overlapped, and the whole or a part of the superposed section is formed into a bag shape by a joint section that joins both the non-woven sheets to each other in the thickness direction thereof, and the bag thereof. Is a bag-shaped overlapping portion in which both non-woven sheets are not joined to each other, and all or more than half of a predetermined cleaning portion which is at least one cleaning portion of the wiping material is the bag-shaped portion. It is characterized by being constituted by the outer surface portion of the non-woven sheet forming the overlapping portion.

When the object to be cleaned is wiped by the predetermined cleaning section of the fiber-made wiping material, dust on the cleaning object enters between the fibers of the non-woven sheet which constitutes the predetermined cleaning section, and the non-constant which constitutes the predetermined cleaning section. The fibers of the woven sheet are entangled in the dust, or the dust is adsorbed to the fibers of the non-woven sheet that constitutes the predetermined cleaning unit, and is wiped off by the predetermined cleaning unit.

In the case of a normal non-woven sheet, as the amount of dust wiped increases, the amount of dust approaches a saturated state, and the wiping ability decreases. However, a part of the dust wiped on the non-woven sheet forming the bag-shaped overlapped portion in the predetermined cleaning portion is, for example, pushed into the dust to be wiped one after another, or almost from the beginning of the wipe. ,
It enters the inside of the bag-shaped overlapped portion, that is, the portion between the two non-woven sheets forming the bag-like overlapped portion, and is retained inside the bag-like overlapped portion. Therefore, in the bag-shaped overlapping portion in the predetermined cleaning unit, the amount of dust until it reaches a saturated state is significantly larger than that of a normal nonwoven sheet, and the amount of dust that can be wiped off as a whole of the predetermined cleaning unit is large. Increase.

Therefore, for example, replacement of the fiber wiping material or 1
When one fiber wiping material has two or more predetermined cleaning parts, it is possible to wipe off dust for a long period of time or in large amounts without changing the predetermined cleaning part.

The fibrous wiping material may be, for example, one sheet-shaped member as a whole, or may be in a form other than the sheet-shaped member (for example, a bag-shaped member having one end opened). The fibrous wiping material may be, for example, one in which two non-woven sheets are stacked to form a single sheet as a whole, or two non-woven sheets may be stacked to form a non-sheet form. The thing (for example, bag-shaped thing) may be used.

The non-woven fabric sheet is made of a fiber such as a synthetic fiber as a main material and is formed into a sheet without a woven process, and includes a so-called non-woven fabric.

The cleaning section refers to a portion of the fiber wiping material for wiping the object to be cleaned and its vicinity, and is made of a non-woven fiber sheet. The cleaning unit may be the whole or a part of the fiber wiping material. The latter includes, for example, a case where a part of the fiber wiping material is held by being sandwiched between the devices and the floor surface or the like is wiped in a mop-like manner. May wipe the object to be cleaned, and in that case, the part of the fiber cleaning material that faces the floor and its vicinity (for example, fold it back to hold the fiber cleaning material by holding it with the device). The vicinity of the closed part) is the cleaning part.

A plurality of cleaning parts can be provided for one fiber wiping material, but one cleaning part may be provided. For example, the fibrous wiping material may be in the form of a single sheet as a whole, and cleaning parts may be provided on the front and back sides of certain parts thereof.

Further, in the fiber-made wiping material of the present invention, all or a part of the fiber-made wiping material is a polymerized portion in which two non-woven sheets are overlapped, and all or a part of the polymerized portion is bag-shaped polymerized. It can be a part.

The bag-shaped overlapping portion is formed in the overlapping portion where two non-woven sheets are overlapped. The bag-shaped overlapping portion is formed in a bag shape by a joining portion that joins both non-woven sheets in the thickness direction thereof. For example, two square non-woven sheets
It is also possible to join two opposite sides of the overlapped portion which are overlapped with each other to form a bag shape in which the other two sides are not joined.
The joining of both non-woven sheets at the joining portion can be performed by, for example, heat fusion or an adhesive. The non-woven sheets are not joined to each other inside the bag-shaped overlapping portion formed in the bag shape. In addition, all or part of the bag-shaped overlapping portion in the predetermined cleaning unit may be closed in a bag shape by a joint portion that joins both nonwoven sheets to each other in the thickness direction over the entire circumference. it can. In this case, the dust that has entered the bag-shaped overlapping portion can be prevented from leaking to the outside. When a plurality of such bag-shaped overlapping portions are present in the predetermined cleaning portion, the dust that has entered the inside of each bag-like overlapping portion is suspended and dispersed.

At least one cleaning section of the wiping material is a predetermined cleaning section. All or more than half of the predetermined cleaning portion is constituted by the outer surface portion of the non-woven sheet forming the bag-shaped overlapping portion. The fibrous wiping material of the present invention can be provided such that a plurality of bag-shaped overlapping portions are present adjacent to the predetermined cleaning portion. The surface of the bag-shaped overlapping portion facing the other nonwoven fabric is the inner surface, and the surface of the bag-like overlapping portion exposed to the outside is the outer surface.

The fibrous wiping material of the present invention may be formed as a single sheet as a whole, and the predetermined cleaning portions may be provided on the front and back of certain portions thereof. in this case,
A part of the dust wiped on the non-woven sheet that forms the bag-shaped overlapping portion at the predetermined cleaning portions on both sides enters the inside of the bag-shaped overlapping portion and is retained. Will increase.

Further, in the fibrous wiping material of the present invention, the outer surface portion of the non-woven sheet forming the bag-shaped overlapped portion in the above-mentioned predetermined cleaning portion is more fluffed than the inner surface portion of the non-woven sheet. You can

For example, in the case of a thermal bond nonwoven fabric, the surface to which heat is applied has little fuzz and the other surface has a lot of fuzz. Can be the inner surface side of the non-woven sheet.

In this case, when the object to be cleaned is wiped with the non-woven sheet forming the bag-shaped overlapping section in the predetermined cleaning section of the fiber wiping material, the outer surface of the non-woven sheet is fluffed as compared with the inner surface thereof. , The dust on the cleaning target is easily wiped and enters the inside of the bag-shaped overlapping portion, and the inner surface of the non-woven sheet is less fluffed than the outer surface thereof, so that the dust entering the inside of the bag-like overlapping portion On the contrary, it is prevented from going out, and dust is effectively retained inside the bag-shaped overlapping portion.

It is preferable that the joint portion in the predetermined cleaning portion is a linear joint portion having a linear shape.

Among the joints for joining the two non-woven sheets to each other in the thickness direction over the entire circumference of the bag-shaped overlapping portion existing in the predetermined cleaning portion, the one in the predetermined cleaning portion is the adjacent bag-like overlapping portion. Since it is a linear joint that forms a line, including the joint that forms the boundary between each other, it is possible to suppress the area of the bag-shaped overlapping portion in the predetermined cleaning unit from being reduced as much as possible, and the predetermined cleaning is performed. As a whole, the amount of dust that can be wiped off can be increased as much as possible.

Further, it is desirable that the outer surface portion of the linear joint portion in the predetermined cleaning portion be formed with a compression concave line along the linear joint portion.

For example, the main portion of the square non-woven sheet is located on the bottom side of the square plate-shaped non-woven sheet holding head, and the two opposite sides of the non-woven sheet correspond to the two corresponding non-woven sheet holding heads. When cleaning with the non-woven sheet on the bottom side of the non-woven sheet holding head while folded back at the side and held on the top side, the non-woven sheet holding of the non-woven sheet holding head of the non-woven sheet holding head Near the two sides of the head,
That is, generally, the effect of wiping off the dust is high in the vicinity of the portion corresponding to the edge of the nonwoven sheet.

A plurality of bag-shaped overlapping portions exist adjacent to each other in the predetermined cleaning portion, and the joint portion in the predetermined cleaning portion is a linear joint portion. The outer surface portion of the linear joint portion in the predetermined cleaning portion is a linear joint portion. However, when forming a compression concave line along the linear joint portion, since the joint portion in the predetermined cleaning portion is a linear joint portion, the area of the bag-shaped overlapping portion in the predetermined cleaning portion is The joint reduces the reduction as much as possible. Further, when the object to be cleaned is wiped by the predetermined cleaning portion in the direction intersecting with the compression concave line, the compression concave line has an effect similar to that of the edge portion corresponding to the above, and therefore, in the vicinity of the compression concave line. The effect of wiping off the dust is enhanced, and the dust can be more effectively wiped off in the bag-shaped overlapping portions that are adjacent to each other with the compression concave line interposed therebetween. Further, since the dust can be wiped in a state of being dispersed in the bag-shaped overlapping portions, the amount of dust that can be wiped can be increased as a whole.

The compression concave line means a linear concave portion fixed in a compressed state in the thickness direction of the nonwoven sheet. For example, by heating and compressing a non-woven fiber sheet along a certain line, a compression concave line can be formed along the line.

The compression concave line may be, for example, a lattice shape, a wave shape, or a combination of the two. The wave shape means a substantially continuous linear shape that repeats at a constant or variable amplitude and wavelength and progresses in a constant or variable direction, and as an example, a semi-circular arc-shaped half wavelength alternates in the opposite direction. Examples thereof include a continuous waveform, a waveform in which sinusoidal curves are continuous, and a zigzag waveform in which half wavelengths of two sides of a triangle alternate in opposite directions.

Such a compressed concave line crosses all or more than half of the predetermined cleaning section so as to cross at least the main wiping direction of the predetermined cleaning section (more preferably two or more, further preferably three or more). It is preferable to have four or more) so that dust can be more effectively wiped off in the bag-shaped overlapping portions that are adjacent to each other with the compression concave line interposed therebetween.

The main wiping direction of the predetermined cleaning portion is the main direction when the object to be cleaned is wiped by the predetermined cleaning portion of the fiber wiping material of the present invention, and the predetermined cleaning portion is the longitudinal direction and the transverse direction orthogonal to it. Is a fixed shape (for example, a rectangle, a square, an ellipse, etc.), it is usually the longitudinal direction or the lateral direction. Of these, the short-side direction in which the wiping range is wide is often the main direction. In the case of a circular shape in which the longitudinal direction and the lateral direction are not defined, either direction can be the main wiping direction. Further, when the fiber wiping material of the present invention is used by being attached to an instrument, if the mode of attachment is fixed, the main wiping direction of the predetermined cleaning part is also fixed.

As described above, as an example of the fibrous wiping material having a compression concave line that crosses at least the main wiping direction of the predetermined cleaning portion in all or more than half of the predetermined cleaning portion,
An example is the case where a large number of bag-shaped overlapping portions are evenly present in all or more than half of the predetermined cleaning portion. In such a case, the area of each bag-shaped overlapping portion is 0.25c in all or more than half of the predetermined cleaning portion.
it is preferred that it is assumed that m ² or more, in all or more than half of the part in a given cleaning unit, it is more preferable area of each bag-like polymer portion is 1 cm ² or more. If the area of each bag-shaped overlapping section in the predetermined cleaning section is too small,
The proportion of the joint portion in the entire predetermined cleaning portion becomes too large, and the effect of wiping off the dust decreases.

FIG. 1 is a plan view of a fiber wiping material as an example of an embodiment of the present invention, FIG. 2 is an enlarged cross-sectional view of a main part of the fiber wiping material of FIG. 1, and FIG. It is a perspective view of the wiping and cleaning tool using the wiping material. A bottom view of this fiber-made wiping material appears the same as the plan view.

This fiber-made wiping material 10 is mainly held on a non-woven fabric holding head 12a of a wiping / cleaning tool 12 shown in FIG. 3 in which a handle 12b is connected to a non-woven fabric holding head 12a having a flat rectangular shape. Although it is used for wiping and the like, it can be used as it is by hand.

In the fibrous wiping material 10, two non-woven fabrics made of synthetic fibers having a rectangular shape in a plane are stacked, and the two non-woven fabrics are joined in the thickness direction thereof by heat compression at a plurality of kinds of linear joint parts. The compression concave line is formed on the outer surface portions on both the front and back sides along the linear joint. Both of the nonwoven fabrics are thermal bond nonwoven fabrics, and the surface on the side to which heat is applied is on the inside and the other surface which is fluffy compared to that surface is on the outside, but the type of nonwoven fabric is not limited to this.

A wave-shaped compression concave curve 14 in which half-wavelengths in a semi-arc shape are alternately continuous in the lateral direction (main wiping direction).
A large number of (the compression concave lines along the linear joint portion) are arranged in parallel in the longitudinal direction in the same phase. When the longitudinal direction is the left-right direction, the right end position of one adjacent compression concave curve 14 and the left end position of the other adjacent compression concave curve 14 coincide with each other. However, the right end position and the left end position of the adjacent compression concave curves 14 may be separated from each other,
May overlap. In addition, such a compression concave curve,
For example, a compression concave line having a waveform in which half wavelengths composed of two sides of a triangle are alternately continuous in opposite directions may be used.

The main wiping direction of the non-woven fabric holding head 12a is the lateral direction in which the wiping range is widened. Fiber cleaning material 1
Both long sides of 0 are joined by two strip-shaped joints 15 extending over the entire length in the longitudinal direction. Inside the both band-shaped joints 15, at symmetrical positions separated by a length in the lateral direction,
Two linear positioning compression recesses 16 (compression recesses along the linear joint) are provided over the entire length in the longitudinal direction. When the fibrous wiping material 10 is held by the non-woven fabric holding head 12a, the inner side sandwiched by the positioning compression concave lines 16 is positioned on the bottom surface of the non-woven fabric holding head 12a, and the outside of each positioning compression concave line 16 is set to the non-woven fabric holding head 12a. It is folded back to the upper surface side and is held by the holding portion of the nonwoven fabric holding head 12a. The two linear positioning compression concave lines 16 facilitate the positioning of the nonwoven fabric holding head 12 a with respect to the fibrous wiping material 10.

The compression concave curve 14 and the positioning compression concave line 16 are both linear concaves fixed in a compressed state in the thickness direction by heating and compression, and are common to both surfaces of the fiber wiping material 10. For easy and reliable formation of compression concave lines,
It is preferable that all or part of the fibers constituting the non-woven sheet in the present invention are fibers that melt when heated (for example, synthetic fibers such as polyester).

The non-woven fabric holding head 1 is provided with the textile wiping material 10.
When used while being held on 2a, the cleaning portion 10a is an inner portion sandwiched between the two linear positioning compression concave lines 16 on each of the front and back surfaces of the fiber-made wiping material 10 and a portion outside thereof.
In the example of FIG. 1, the cleaning unit 10a has a compression concave curve 14 for 1.5 wavelengths in the lateral direction, and two linear longitudinal compression concave lines 18 are provided for each half wavelength. The longitudinal compression concave line 18 is formed in the same manner as the compression concave curve 14 and the positioning compression concave line 16.

The cleaning portion 10a is a predetermined cleaning portion, and each portion surrounded by two or three of the band-shaped joint portion 15, the positioning compression concave line 16, the compression concave curve 14 and the longitudinal compression concave line 18 is The bag-shaped overlapping portion 20 is closed in a bag shape by the peripheral joining portion, and the inside 20a of the bag-like overlapping portion 20 is not joined to both non-woven sheets. The cleaning unit 10a is
Almost all of them are a large number of bag-shaped overlapping portions 2 which are adjacent to each other.
The outer surface of the non-woven fabric forming 0 is formed. The bottom surface side of the fiber wiping material 10 is similar to the flat surface side.

The fibrous wiping material 10 is held by the non-woven fabric holding head 12a of the wiping / cleaning tool 12, and the fibrous wiping material 10 is made.
When the cleaning target is wiped by the cleaning unit 10a, the dust on the cleaning target enters between the fibers of the non-woven fabric forming the cleaning unit 10a, and the fibers of the non-woven fabric forming the cleaning unit 10a are entangled in the dust. Alternatively, the dust is adsorbed to the fibers of the non-woven fabric forming the cleaning unit 10a, and is wiped off by the cleaning unit 10a.

A part of the dust wiped on the non-woven fabric forming the bag-shaped overlapping portion 20 in the cleaning portion 10a is pushed, for example, into the dust to be wiped one after another, or almost from the beginning when it is wiped off. The inside 20a of the bag-shaped overlapping portion 20, that is, the portion between the two non-woven fabrics forming the bag-like overlapping portion 20, enters the inside 20a of the bag-like overlapping portion 20.
Reserved in a. In particular, the outer surface portion of the non-woven sheet forming the bag-shaped overlapping portion 20 in the cleaning portion 10a is more fluffy than the inner surface portion thereof, so that dust on the cleaning target is wiped off and the inside 20a of the bag-like overlapping portion 20 is wiped off. Since the non-woven sheet is easy to enter and the inner surface portion of the non-woven sheet is less fluffed than the outer surface portion thereof, the dust that has entered the inside 20a of the bag-shaped overlapping portion 20 is prevented from going out to the outside, and the bag-like overlapping portion is prevented. Inside 20
The dust is effectively retained in a.

Therefore, in the bag-shaped overlapping portion 20 of the cleaning portion 10a, the amount of dust until it reaches a saturated state is significantly larger than that of a normal nonwoven fabric, and the cleaning portion 10a is large.
As a whole, the amount of dust that can be wiped off increases.
In addition, the bag-shaped overlapping portion 20 in the cleaning portion 10a on both front and back sides.
Since a part of the dust wiped on the non-woven sheet forming the sheet enters the inside 20a of the bag-shaped overlapping portion 20 and is retained,
The amount of dust that can be wiped off the cleaning portions 10a on both sides increases.

In the cleaning section 10a, a large number of bag-shaped overlapping sections 20 are present adjacent to each other, and the joint section in the cleaning section 10a is a linear joint section. Since the outer surface portion forms the positioning compression concave line 16, the compression concave curve 14, and the longitudinal compression concave line 18,
When the cleaning target is wiped by the cleaning unit 10a in the direction intersecting with these compression concave lines, the compression concave curve 14 and the longitudinal compression concave line 18 have the effect of conforming to the edge equivalent portion,
The effect of wiping off the dust is enhanced in the vicinity of the compression concave lines, and the dust can be more effectively wiped at the bag-shaped overlapping portions 20 adjacent to each other with the compression concave curve 14 and the longitudinal compression concave line 18 interposed therebetween. In addition, dust is collected in each bag-shaped overlapping section 2
Since the particles can be wiped in a state of being dispersed in 0, the amount of dust that can be wiped can be further increased as a whole. The two longitudinal compression concave lines 18 are provided so as to cross the main wiping direction in the entire cleaning portion 10a, and the plurality of compression concave curves 14 are also provided so as to intersect. A large number of compression concave curves 14 are crossed in the direction orthogonal to the main wiping direction. Therefore, the bag-shaped overlapping portions 2 that are adjacent to each other with the compression concave line in between
At 0, dust can be wiped off more effectively.

Unless otherwise stated, the number of components, the material, the shape, the relative arrangement, etc. of the constituent parts in the above description of the embodiments are limited to only those parts. It is not intended to be limited to the above and is merely an example of description. In addition, the description including the examples and numerical ranges described for the present invention in the section of the means for solving the problems is applied to the above description of the embodiments in principle.

[0045]

According to the fiber-made wiping material of the present invention, part of the dust wiped on the non-woven sheet forming the bag-shaped overlapping portion in the predetermined cleaning portion enters the inside of the bag-like overlapping portion, Since the bag-shaped overlapped part in the predetermined cleaning part is retained inside the bag-shaped overlapped part, the amount of dust to be wiped up to a saturated state is significantly larger than that of a normal nonwoven sheet, and the predetermined cleaning is performed. As a whole, the amount of dust that can be wiped off increases. Therefore, for example, it is possible to wipe off a large amount of dust for a long period of time without changing the fibrous wiping material or changing the predetermined cleaning portion when one fibrous wiping material has two or more predetermined cleaning portions. .
