Description

  The present invention relates to a functional sheet such as a cleaning sheet for cleaning a flooring or the like mounted on the cleaning unit of a cleaning tool including a cleaning unit and a rod-shaped handle connected to the cleaning unit. In some cases, it is used as a functional sheet for floor protection such as floor protection, polishing, and waxing of flooring materials used for care. In addition, the functional sheet is not limited to a cleaning sheet, and can be used as a wet tissue, a towel, a body wipe, a makeup remover, and the like.

As a conventional mop-shaped cleaning tool, for example, cleaning that removes foreign matter such as dust, hair, solid dust, stains, and adhering liquid on the floor, cleaning of the floor such as protection of the floor, polishing, etc. Is known as a functional sheet.
For example, as described in Patent Document 1, a type of cleaning sheet that is impregnated with a cleaning agent and directly wiped by hand is known. However, when this is mounted on a mop-shaped cleaning tool for cleaning, it is difficult to achieve both stains on the floor, cleanability, and operability of lightly wiping with one hand.
Patent Document 2 describes a cleaning sheet that is impregnated with a cleaning agent and wiped by hand. When the cleaning sheet is attached to a mop-shaped cleaning tool, the long fiber may be caught by a protrusion on the floor and the sheet may be torn. Moreover, when it is used by being mounted on a mop-shaped cleaning tool, the cleaning agent is excessively discharged at the beginning of wiping, and there is no sustainability even if it is desired to clean a large area.
Accordingly, as described in Patent Document 3, Patent Document 4, and Patent Document 5, a disposable cleaning sheet is generally cleaned by supplying a cleaning agent or water to the cleaning sheet or the floor.

  In addition to the cleaning tool equipped with the cleaning sheet, such a cleaning method is very time-consuming, such as holding a cleaning agent in the hand, and removing the sheet from the cleaning tool in the middle of cleaning to wet it with water. In addition, when the amount of squeezing after wetting with water is weak, water may be excessively applied to the floor at the initial stage of cleaning, and the dirt may be spread on the contrary. Moreover, when the strength of the handle is weak like a mop for dry cleaning, the operability may be deteriorated. Furthermore, cracks such as cracks may be given to some wooden floors. In addition, although the above publication uses a cleaning sheet having a spunlace nonwoven fabric on the surface, the cleaning sheet is not sufficiently entangled with foreign matter such as hair and cotton dust in a water-containing state.

Japanese Utility Model Publication No. 4-89251 Japanese National Patent Publication No. 11-508256 Japanese Patent Laid-Open No. 10-262883 JP-A-10-286206 JP-A-9-131288 JP-T-2005-507271 JP 2005-42290 Gazette

In particular, although Patent Document 1 discloses a cleaning sheet, there is no technical idea of storing a substance in a base material in a lattice pattern formed on the surface. Further, Patent Document 2 discloses a technique in which hair or the like protrudes from the surface of the support as a result of the rubbing operation. There is no technical idea of storing.
Patent Document 3 discloses a configuration that has good slipperiness, excellent water absorption and water retention, and can be used for both dry wiping and water wiping. Since the three-layer sheet is pressed and depressed at the joining line portion, a swell is formed on the sheet at the boundary between the joining line and the non-joining line, and dirt is scraped off at the swelled portion. Although there is a description that the effect is exhibited (paragraph [0034]), there is no idea of storing a substance in the cleaning sheet.
Furthermore, the embossed cleaning sheet of Patent Document 4 has a plurality of convex portions, and each convex portion is divided by a linear concave portion. In this embodiment, a continuous rhombus-like pattern is formed by the recess, and therefore there is no concept of storing a substance in the cleaning sheet.

  Patent Document 5 includes a wiping portion made of a liquid-permeable cleaning sheet and a liquid absorber that absorbs the liquid wiped by the wiping portion, and the cleaning sheet has a number of convex portions. In this technique, the area of the convex portion that contacts the surface to be cleaned at the time of cleaning is 5 to 60% with respect to the area of the entire cleaning sheet. However, as a result of experiments conducted by the inventors, the area of the convex portion that contacts the surface to be cleaned during cleaning is more than 5 to 60% of the total area of the cleaning sheet. Cleaning sheet used for removing stains, stains, adhering liquids, protecting floors, polishing, etc. works on dust, hair, solid debris, smudges, adhering liquids etc. and subsequent flow. Turned out to be affected.

  Furthermore, in Patent Document 6, a wiping substrate used in combination with substances such as ingredients and blending is disposed on the surface of a synthetic resin sheet found in the home or workplace, and the substance is applied to the substrate. The concept of storing is used. The shear force-sensitive micropockets described in Patent Document 6 are fine-scale three-dimensional sections in the surface of the substrate, and along the surface of the substrate when the substrate is in contact with the target surface. When a shearing force is applied, the shearing force substantially deforms the wall surface of the micropocket and releases the substance to the target surface. However, even when the base material has a plurality of micro pockets, when the cleaning part of the cleaning tool is reciprocated from the front to the back as shown in the example of FIGS. 19 to 27 published in Patent Document 6, When reciprocating left and right, moving in a specific direction guides dust on the floor, hair, solid debris, stains, adhering liquid, etc., and moves directly from one side of the cleaning part of the cleaning tool to the other opposite side. Therefore, the foreign matter securing efficiency does not increase.

In addition, in patent document 7, a pulp fiber layer is located between two card web layers, this is mounted on the support body of a coarse plain weave structure, a high pressure water stream is injected, and fibers are intertwined. In addition, a kitchen towel is disclosed in which a plurality of low integration regions and a plurality of high integration regions having a thickness larger than the thickness of the low integration region are formed to obtain a kitchen towel.
However, although it is distinguished from the low integration area and the high integration area, the maximum and minimum peak values of the low integration area and the high integration area, and the boundary between them are not clearly separated. It is not specified and is unknown. In particular, the highest peak value and the lowest peak value are connected to the top and bottom of FIG. 1 published in Patent Document 7, but on the foreign matter such as dust on the floor, hair, solid dust, stain stains, adhering liquid, etc. Even if a kitchen towel is placed on the wall, it cannot be secured as a foreign object.

  Therefore, the present invention eliminates such conventional problems, and is used for floor management such as dust on the floor, hair, solid dust, stain stains, adhering liquid and other foreign matters, floor protection, and polish. It is an object of the present invention to provide a functional sheet that can be used as a cleaning sheet for securing good foreign substances, wet tissue, hand towels, body wipes, makeup removers, and the like.

The functional sheet according to the invention of claim 1 draws a virtual reference line perpendicular to two opposing sides of a rectangular reference sheet made of a nonwoven fabric sheet or a woven fabric sheet, and is drawn with respect to the drawn virtual reference line A plurality of independent filaments formed with the same filament thickness, the same filament length, the same filament spacing, and the same filament number on the reference sheet surface with the inclination of −45 degrees and +45 degrees by the collection of nonwoven fabric fibers. A group is formed. Incidentally, the whole of the present invention is generally similar to the overall conceptual shape in which the four-folded stripes (four-folded) are inclined 45 degrees.
Moreover, the virtual straight line connecting the lowest ends of the filaments in the adjacent independent filament group is at the overlapping position where the virtual straight lines connecting the highest ends of the filaments at the shortest distance from the adjacent independent filament group overlap. Since it is formed, the foreign matter moving between the filaments collides with or is guided by the filaments of the independent filament group, and therefore passes straight through the lower surface of the cleaning unit, that is, the cleaning unit body surface. There is no.

Here, the reference sheet is a rectangular sheet (artificial paper) made of a nonwoven fabric sheet or a woven fabric sheet. This reference sheet may be net-like or plain. It may be a material that has been slightly embossed.
In addition, the same-thickness and same-length line formed at the inclination angles of −45 degrees and +45 degrees draws a virtual reference line perpendicular to the opposing long sides of the reference sheet. With respect to the virtual reference line, it is formed by a collection of non-woven fibers on the reference sheet surface, and the non-woven fibers of long fibers are entangled with the non-woven fibers of short fibers by high-pressure water flow. It is sufficient that the density of the filaments is dense and the mass is also large.
The density of fibers of the above-mentioned filaments (independent filament group) is high and the mass is large. The fiber density of the nonwoven fabric sheet or the nonwoven fabric sheet can be formed high, and the liquid absorption and retention ability is large due to capillary action. Is intended to do.

  The plurality of independent line groups are drawn on the front or back surface of a virtual reference line perpendicular to two opposite sides (or even one side) of the reference sheet, with respect to the drawn virtual reference line. The reference sheet surface is formed by a set of non-woven fibers with an inclination of −45 degrees, the same line length and the same line interval, and with the inclination of +45 degrees, the same line thickness, the same line length, A group of filaments formed at the same filament spacing and independent of each other. Here, the -45 degree and +45 degree filaments of the plurality of independent filament groups are formed with the same filament thickness, the same filament length, the same filament interval, and the same filament number. is there. Of course, these are not a problem if the error is small, but even if they have an error of 10 to 30%, they cannot be implemented and can be implemented. In this embodiment, since it is only specified from the appearance, it does not deny the intervention of error.

  Furthermore, the virtual straight line connecting the lowest ends of the filaments in the adjacent independent filament group overlaps the virtual straight line connecting the uppermost ends of the filaments at the shortest distance from the adjacent independent filament group. Formed. Here, the overlapping position where the virtual straight line connecting the lowest end of the line in the independent line group and the virtual straight line connecting the top end of the line at the shortest distance from the independent line group overlaps, The overlap may be a virtual straight line having an overlapping width where a virtual straight line connecting the bottom ends and a virtual straight line connecting the top ends overlap.

  The functional sheet of the invention of claim 1 draws a virtual reference line perpendicular to the opposing long sides of a rectangular reference sheet made of a nonwoven fabric sheet or a woven fabric sheet, and with respect to the drawn virtual reference line The filaments formed so that the inclination angles of −45 degrees and +45 degrees do not intersect with the reference sheet surface due to the collection of non-woven fibers, the filaments of −45 degrees and the filaments of +45 degrees are the same filament thickness. And a plurality of independent line groups formed with the same line length, the same line interval, and the same number of lines.

  Moreover, the virtual straight line connecting the lowest ends of the filaments in the adjacent independent filament group is at the overlapping position where the virtual straight lines connecting the highest ends of the filaments at the shortest distance from the adjacent independent filament group overlap. Since the foreign matter that moves between the filaments collides with the filaments of the independent filament group, and the reflected foreign substances collide with the filaments in the independent filament group one after another, the cleaning unit In addition to eliminating the leakage of cleaning that does not collide with the lower surface of the cleaning unit main body surface, the line in the independent line group causes dust on the floor, hair, solid dust, stain stains, Foreign matter such as adhering liquid can be submerged and held repeatedly, or floor management such as floor protection and polishing can be performed.

Therefore, when the strip formed so as not to intersect at an inclination angle of −45 degrees and +45 degrees is repeatedly linearly reciprocated from the front to the back of the cleaning part of the cleaning tool, or when the cleaning part is swung left and right, for example, Foreign matter such as dust on the floor, hair, solid debris, etc., when the cleaning part of the cleaning tool is repeatedly reciprocated from the front to the back, the collision angle of 45 degrees with respect to the filaments with inclination angles of +45 degrees and -45 degrees Similarly, it collides with the adjacent strips of +45 degrees and −45 degrees by the reflection of 45 degrees. At this time, since the repulsion coefficient of the filaments having the inclination angles of +45 degrees and −45 degrees is small, the filaments are secured by any of the filaments, and the density of the filaments and the mass of the filaments are involved in this securing.
In addition, a rectangular reference sheet made of a nonwoven fabric sheet or a woven fabric sheet is located above the floor surface in the thickness direction, and even if it is on dust, hair or solid waste on the floor, it retains them by elasticity. The 45-degree reflections collide with adjacent +45 degree and -45 degree inclined lines, making it difficult to leave a rectangular reference sheet made of a nonwoven fabric sheet or a woven fabric sheet.

  The plurality of independent filament groups are composed of the filaments, and the force applied to the cleaning part of the cleaning tool appears as the elasticity of each thread of the filament, so the pressing force per unit area of the functional sheet It is possible to increase the size, and it is possible to respond appropriately to cleaning or floor protection and management. And since the density change arises in the line | wire space | interval of the said independent line | wire group by the manufacturing process, a foreign material can sneak into any position and it can be hold | maintained.

  Furthermore, both ends of the independent line group adjacent in the extending direction of the line include the line of the adjacent independent line group that intersects at an angle of 90 degrees if an extended line is drawn, and the line interval Since the foreign matter does not pass straight through the surface, the foreign matter enters the functional sheet at any position and is entangled. Even when a downward force is applied to the cleaning portion of the cleaning tool, the foreign material is entangled with the functional sheet by the vertical elastic force and the elastic force between the gaps, so that the foreign material holding force is improved.

In addition, since the nonwoven fabric sheet or the woven fabric sheet in the independent filament group and the filaments has a dense fiber density and a large mass, the nonwoven fabric sheet or the woven fabric sheet has a fiber density. Since it can be formed high, the ability to absorb and retain liquid is increased by capillary action.
Therefore, it can be used in cleaning sheets that are used for floor management such as dust on the floor, hair, solid debris, stain stains, adhered liquids, floor protection such as floor protection, polish, etc. Since the reference sheet and the independent filament group move independently and function as a wet tissue, a towel, a body wipe, a makeup remover, etc., it is an object to provide a functional sheet.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that, in the embodiments, the same reference numerals and the same reference numerals are the same or corresponding functional parts, and therefore, redundant description thereof is omitted here.

[Embodiment 1]
First, the case where the functional sheet of Embodiment 1 of the present invention is the cleaning sheet 1 will be described with reference to the drawings.
As shown in FIGS. 1 and 2 , the conventional cleaning tool 10 includes a rectangular cleaning unit 11 parallel to the floor surface, a biaxial connection unit 12 rotatably connected to the cleaning unit 11, and It has a rod-like handle 13 that is connected to the biaxial connecting portion 12 and can be moved up and down, and can be extended, and the cleaning tool 10 is engaged with the four or six corners of the cleaning sheet 1. The cleaning part 11 connected to the rotating biaxial connecting part 12 has an opposite side to which the biaxial connecting part 12 is connected. The surface of the cleaning unit 11 is a cleaning unit main body surface 15.

The cleaning sheet 1 as a functional sheet is mounted so as to cover the cleaning unit main body surface 15 on the lower surface of the cleaning unit 11 and to be engaged with the sheet holding units 14 at the four left and right corners. Therefore, after wetting with water and squeezing excess water, it can be used as it is for cleaning. That is, the cleaning sheet 1 can clean the floor surface and the like in the same manner as a normal mop.
In this type of cleaning sheet 1 according to the present embodiment, since the reference sheet 2 is formed of pulp fibers and thermoplastic fibers, the friction resistance value during cleaning is low, and water can be wiped smoothly with a light force. it can.

In addition, the rectangular reference sheet 2 and the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc, Rd are integrated, and even if wet with water or impregnated with wax, Even if the cleaning sheets 1 are squeezed strongly, the fibers do not separate. Here, the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd mean straight filaments formed as ellipses in the plan view. For example, it is assumed that this includes a chamfered corner.
Here, the non-woven fabric refers to a fabric bonded by a chemical or physical method without weaving chemical fibers, glass fibers, metal fibers, natural fibers, and the like. The manufacturing process is short-term and low cost. The reference sheet 2 is a long fiber, and the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd are formed by a process in which short fibers are entangled.

Next, the cleaning sheet 1 as a functional sheet of the present embodiment will be described.
The reference sheet 2 is composed of a nonwoven fabric sheet or a woven fabric sheet. The reference sheet 2 is provided with a hole made of a plurality of round holes (not shown) on a plane. In this Embodiment, the reference | standard sheet | seat 2 is comprised with the nonwoven fabric sheet, and the fistula sheet | seat is created using a specific sheet | seat pattern so that the entanglement in a later process is possible. The plurality of holes are not complete hollow holes, but are formed of non-woven long fibers so that they can be entangled with the short fibers in a later step, and are formed thinly in a so-called spider web.
Moreover, when implementing this invention, the reference | standard sheet | seat 2 may form the hole part which is not shown in figure which cooperates with jet spray, and may form the fistula sheet | seat which can be entangled. When the reference sheet 2 is a woven fabric, it is preferable that the hole made of a plurality of round holes is a square hole made of warp and weft.

  Although the reference sheet 2 is composed of a nonwoven fabric sheet or a woven fabric sheet, the reference sheet 2 may be generally embossed except around a hole (not shown). That is, the reference sheet 2 made of a nonwoven fabric sheet may be flush with the surface other than the hole and its surroundings by embossing. Alternatively, in the final step, embossing may be performed to fix the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd of the short fibers to the long fiber reference sheet 2. In particular, it is suitable for determining individual shapes of the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd.

A virtual reference line XX perpendicular to the opposing long sides 2A and 2B of the rectangular reference sheet 2 is drawn, and a set of non-woven fibers is formed on the surface of the reference sheet 2 with respect to the drawn virtual reference line XX. theta = +45 degrees tilt angle formed by the striatum La, Lb, Lc, to form an Ld, striatum at a tilt angle of theta = -45 ° Ra, Rb, Rc, the filament so Rd do not intersect with each other ing.
Here, theta = +45 degrees tilt angle of the linear La, Lb, Lc, and Ld, θ = -45 ° tilt angle of the linear Ra, Rb, Rc, and striatum formed so Rd does not intersect Does not intersect with the actual lengths of the filaments La, Lb, Lc, Ld formed on the surface of the reference sheet 2 and the filaments Ra, Rb, Rc, Rd, and does not have a intersecting length. Is.

  Furthermore, a virtual straight line MM connecting the lowest ends of the filaments Ra, Rb, Rc, Rd in the same independent filament group (independent filament group R composed of the filaments Ra, Rb, Rc, Rd), An imaginary straight line NN connecting the uppermost ends of the filaments at the shortest distance from the adjacent independent filament group is formed to have an overlapping width δ. Although not shown, the same applies to the independent filament group (independent filament group L composed of filaments La, Lb, Lc, and Ld). At this time, the foreign matters moving through the intervals of the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc, Rd are the filaments La, Lb, Lc, Ld of the independent filament groups R, L, the filaments. Ra, Rb, Rc, Rd repeatedly collide, sink, and then held by the independent filament groups R, L, so that foreign matter collides with the cleaning unit main body surface 15, that is, the cleaning unit main body surface 15, and undergoes reflection. Never go straight. That is, the foreign matter does not directly escape through the long side 2A and the long side 2B, the short side 2C, and the short side 2D of the rectangular reference sheet 2 facing each other.

In addition, the lines La, Lb, Lc, Ld of θ = + 45 degrees and the line Ra of θ = −45 degrees formed with the same line thickness, the same line length, the same line interval, and the same number of lines. , Rb, Rc, Rd, the plurality of independent filament groups R, L in the present embodiment has four filaments, a filament thickness of 1 mm, a filament length of 20 mm, and a filament spacing of 20 mm. The distance between the filaments is 2.5 mm, the distance between the independent filaments R and L is 36.4 mm , and the independent filaments are separated by the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd. R and L are formed.
In particular, the filaments La, Lb, Lc, and Ld, the filaments Ra, Rb, Rc, and Rd prevent the passage of foreign matter, and the filaments La, Lb, and Lc are entangled with the long fibers and the short fibers. , Ld, and rods Ra, Rb, Rc, and Rd are held in the dam and are held by foreign objects.
The size of the independent line groups R and L is 3 to 10 times larger than the figure of the conventional cleaning sheet, but the independent line groups R and L are individually divided into the conventional figures. It has been confirmed that it can maintain a degree of flexibility and can be used as a wet tissue, a towel, a body wipe, a makeup remover, and the like.

Next, manufacturing of the cleaning sheet 1 of the present embodiment will be described with reference to FIGS.
In FIG. 7, the reference sheet 2 is supplied from the outside. A conveyor 21 such as a wire net conveyor composed of a conveyance roller and a conveyance roller can freely convey the reference sheet 2 from the left to the right in the drawing. The spunlace processing unit 23 is provided with a spunlace nozzle (nonwoven fabric nozzle) 31 that entangles the aggregate of short fibers with the reference sheet 2, and in this embodiment, the design change according to the good workability and the application. Since it is easy, the spunlace method which entangles a fiber with a high-pressure water stream is used for manufacture of the cleaning sheet 1. In addition, a baffle plate (not shown) and an air nozzle 24 that rectify the air flow are disposed at the inlet of the spunlace processing unit 23.

The collection tank 25 is a container for collecting excess liquid containing excess short fibers not used for the filaments La, Lb, Lc, Ld or the filaments Ra, Rb, Rc, Rd. The liquid containing the fiber is stirred and at the same time, the foreign matter such as dust is removed, and the liquid is supplied to the stirring filter 26 through which only the target short fiber passes. The required amount of short fibers and liquid are mixed and supplied by the stirring filter 26.
Fluid consisting of short fibers and liquid is supplied by pumps 27A and 27B that are independently arranged to circulate the fluid. The pump 27A and the pump 27B that generate a predetermined pressure to supply the fluid pass through the conduit 28 and the conduit 29, and the manifold 30 or the manifold 47 is fed with the fluid in which the short fibers are agitated.

A plurality of spunlace nozzles 31 are disposed in the manifold 30 at an angle of −45 degrees and an angle of +45 degrees with respect to the length direction (traveling direction) of the conveyor 21. In other words, the spunlace nozzle 31 is −45 degrees with respect to the traveling direction of the conveyor 21 of the spunlace processing unit 23 (the displacement is inclined 45 degrees to the left when the traveling direction of the conveyor 21 is the axis). .
That is, with respect to the central imaginary line XX of the conveyor 21, the moving direction is −45 degrees (displaced at an angle of 45 degrees to the left) and the moving direction is +45 degrees (displaced at an angle of 45 degrees to the right). A plurality of spunlace nozzles 31 are arranged. Therefore, the jet spray 31a is sprayed from the plurality of spunlace nozzles 31 arranged. Thus, the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd are formed on a specific surface of the reference sheet 2, for example, the surface.

At this time, the pressure regulator 32 is disposed in the pipe line 28 of the manifold 30, adjusts the pressure of the spunlace nozzle 31, adjusts the energy of the spunlace method in which the fibers are entangled with the high-pressure water flow between the reference sheet 2, The fiber is entangled with the reference sheet 2 with a high-pressure water flow. Thereby, the position and cross-sectional shape of the filament La, Lb, Lc, Ld, the filament Ra, Rb, Rc, Rd with respect to the reference sheet 2 are specified.
That is, the reference sheet 2 is provided with a plurality of round holes on the plane, and in the example shown in FIG. 3, the lines La, Lb, Lc, Ld, the lines Ra, Rb, Rc are formed by the plurality of holes. , Rd.

As in the present embodiment, the reference sheet 2 uses a plurality of provided holes, one of the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd. Is firmly entangled with the reference sheet 2 and embossed in the final process, the integration of the reference sheet 2 and the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc, Rd is strengthened. . The plurality of holes may be three to five, or the oval filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd are initially provided without any holes. You may form from.
According to the experiments by the inventors, the reference sheet 2 was formed from the beginning with the number of holes provided and the ellipse-shaped filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd. In some cases, a large difference in mechanical strength was not obtained, but the one provided with five holes on both sides was mechanically the reference sheet 2 and the filaments La, Lb, Lc, Ld, the filament Ra, It was difficult to separate Rb, Rc and Rd.

  At this time, the positions of the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd of the reference sheet 2 are set so as to obtain the timing at which the jet spray 31a is ejected from the spunlace nozzle 31 by a sensor (not shown). The injection control. In the present embodiment, the jet spray 31a from the spunlace nozzle 31 is controlled, but the conveyor 21 may be repeatedly finely moved, or may be moved or stopped by a stepping operation.

The squeezing roller 34 is disposed at the exit of the spunlace processing unit 23 where the spunlace nozzle 31 is disposed, and the filaments La, Lb, Lc disposed on one surface of the reference sheet 2 and the reference sheet 2. , Ld and the filaments Ra, Rb, Rc, Rd are squeezed, and the reference sheet 2 and the filaments La, Lb, Lc, Ld and the filament Ra disposed on the upper surface of the reference sheet 2 are reduced. , Rb, Rc, and Rd.
The conveyor 21 conveys the reference sheet 2 to the end thereof, and is sucked to the outer surface of the large-diameter pulley 40 whose inside is depressurized during that time, rotates along the large-diameter pulley 40, and the filament La on the opposite surface , Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd.

In the reference sheet 2 placed on the conveyor 21, the filaments La, Lb, Lc, and Ld and the filaments Ra, Rb, Rc, and Rd are formed by the spunlace processing unit 23. Therefore, the filament La on the remaining surface is formed. , Lb, Lc, Ld or the filaments Ra, Rb, Rc, Rd are formed by the spunlace processing unit 43.
The spunlace processing unit 43 also performs injection control by obtaining a timing at which the jet spray 44a is injected from the spunlace nozzle 44 by a sensor (not shown). In the present embodiment, the jet spray 44a from the spunlace nozzle 44 is controlled, but the conveyor 41 may be repeatedly finely moved and a stop operation may be performed.

The pressure regulator 45 is disposed in the pipe line 29 of the manifold 47, adjusts the pressure of the spunlace nozzle 44, adjusts the energy of the spunlace method in which the fibers are entangled with the high pressure water flow between the reference sheet 2 and the high pressure water flow. The degree of the process of entwining the fibers with the reference sheet 2 is adjusted. Thereby, the position and sectional shape of the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd with respect to the reference sheet 2 are specified.
That is, the reference sheet 2 is provided with a plurality of round holes on the plane, and in the example shown in FIG. 2, the plurality of holes are entangled with the mating member, and the filaments La, Lb, Lc, One ellipse of Ld or filaments Ra, Rb, Rc, Rd is formed.
The squeezing roller 46 is disposed at the outlet of the spunlace processing unit 43 in which the spunlace nozzle 44 is disposed, and the reference sheet 2 and the filaments La, Lb, Lc, Ld disposed on the reference sheet 2 and the wire. The water contained in the strips Ra, Rb, Rc, Rd is reduced. A baffle plate (not shown) and an air nozzle 42 that rectify the air flow are disposed.

As a result, the reference sheet 2 makes a U-turn with the large-diameter pulley 40 and starts forming the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd on the opposite surface of the reference sheet 2. Basically, since the surface of the reference sheet 2 is reversed by the large-diameter pulley 40, the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc, Rd of the reference sheet 2 are entangled first. The formation of the opposite surface is then.
In this case, with respect to the central imaginary line of the conveyor 41, a plurality of θ = + 45 degrees (displacement inclined at an angle of 45 degrees to the right) and θ = −45 degrees (displacement inclined at an angle of 45 degrees to the left). Arranged spunlace nozzles 44 are provided. Therefore, the jet spray 44a is ejected from the plurality of spunlace nozzles 44 arranged.
The pressure regulator 45 is disposed in the pipe line 29 of the manifold 47, adjusts the pressure of the spunlace nozzle 44, and converts the energy of the spunlace method in which fibers are entangled with the high-pressure water flow between the reference sheet 2 and the spunlace processing of the conveyor 21. The section 23 and the spunlace processing section 43 of the conveyor 41 are adjusted independently.

  Therefore, when the reference sheet 2 is introduced from outside into the spunlace processing unit 23, the jet spray 31 a is sprayed from the spunlace nozzle 31, and the spunlace processing unit 23 between the conveyors 21 has short fibers on the reference sheet 2. It becomes the process which a fiber is entangled with the reference | standard sheet | seat 2 by the high-pressure water flow between nonwoven fabric fibers. That is, the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd of the reference sheet 2 are entangled. Next, a jet spray 44a is sprayed from the spunlace nozzle 44, and the spunlace processing section 43 between the conveyors 41 entangles the fibers with the reference sheet 2 by high-pressure water flow between the reference sheet 2 and the non-woven fibers of short fibers. This is a process of intertwining the filaments Ra, Rb, Rc, Rd and the filaments La, Lb, Lc, Ld of the reference sheet 2.

The cleaning sheet 1 as the functional sheet of the present embodiment formed in this manner is a virtual reference that is perpendicular to the opposing long sides 2A and 2B of the rectangular reference sheet 2 made of a nonwoven fabric sheet or a woven fabric sheet. Line XX is drawn on the surface, and the reference sheet 2 is formed so that the inclination angles of θ = −45 degrees and θ = + 45 degrees do not intersect with the reference sheet 2 by the collection of non-woven fibers with respect to the drawn virtual reference line XX The filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd, the +45 degree filaments La, Lb, Lc, Ld and the -45 degree filaments Ra, Rb, Rc, Rd Are formed with the same line thickness, the same line length, the same line interval, and the same number of lines.

  Furthermore, the imaginary straight line MM connecting the filaments La, Lb, Lc, Ld in the adjacent independent filament group R, L and the lowest end of the filaments Ra, Rb, Rc, Rd is adjacent to the same It is formed to have an overlap width δ that overlaps with the line La, Lb, Lc, Ld at the shortest distance from the independent line group and the virtual straight line NN connecting the uppermost ends of the lines Ra, Rb, Rc, Rd. Here, the imaginary straight line MM connecting the lowest ends of the filaments La, Lb, Lc, Ld or the filaments Ra, Rb, Rc, Rd in the independent filament groups R, L and the independent filament groups R, L The overlapping width δ where the imaginary straight line N-N connecting the filaments La, Lb, Lc, Ld and the top ends of the filaments Ra, Rb, Rc, Rd at the shortest distance from each other is the imaginary line connecting the bottom ends. The straight line MM and the virtual straight line NN connecting the uppermost ends may be a single virtual straight line (overlap width δ = 0), or may have an overlap width δ.

  Moreover, the imaginary straight line MM connecting the filaments La, Lb, Lc, Ld and the lowest ends of the filaments Ra, Rb, Rc, Rd in the same independent independent line group R, L is adjacent to the same independent line. A line La, Lb, Lc, Ld at the shortest distance from the line group R, L and an imaginary straight line NN connecting the uppermost ends of the lines Ra, Rb, Rc, Rd are formed in an overlapping width δ. Therefore, even if the foreign matter moves in the interval between the line La, Lb, Lc, Ld and the line Ra, Rb, Rc, Rd (the upper part is a part of the reference sheet 2), the line of the independent line group R, L Since it collides with the strips La, Lb, Lc, Ld and the strips Ra, Rb, Rc, Rd, and reflects and collides one after another, it passes straight through the cleaning portion main body surface 15 and there is no cleaning leakage. In other words, due to the overlapping width δ, no foreign matter passes directly between the opposing long side 2A and the long side 2B and between the short side 2C and the short side 2D of the reference sheet 2.

  Therefore, the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd formed so as not to intersect at an inclination angle of −45 degrees and +45 degrees are located on the front side of the cleaning portion main body surface 15 of the cleaning tool 20. When the cleaning unit body surface 15 is repeatedly moved back and forth from side to side or the cleaning unit body surface 15 is swung left and right on the straight line, for example, foreign matter such as dust on the floor, hair, solid dust, etc. 45 degrees with respect to the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd at an inclination angle of θ = + 45 degrees and θ = −45 degrees when reciprocating back and forth from the front. It collides at the collision angle, and similarly collides with the adjacent filaments with inclination angles of +45 degrees and −45 degrees by reflection of 45 degrees. At this time, the coefficient of restitution of the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc, Rd having an inclination angle of the overlap width δ = + 45 degrees and the overlap width δ = −45 degrees is small, and the individual nonwoven fabrics Since it is held by the fiber, foreign matter is secured by any of the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd. In addition, the rectangular reference sheet made of a nonwoven fabric sheet or a woven fabric sheet is located in the middle of its thickness direction, and even if it is on dust, hair, solid waste on the floor, it is held by elasticity, 45 degrees A rectangular reference made of a nonwoven fabric sheet or a woven fabric sheet colliding with adjacent filaments La, Lb, Lc, Ld and filaments Ra, Rb, Rc, Rd having an inclination angle of +45 degrees and -45 degrees by reflection of It becomes difficult to leave the seat 2.

In addition, both ends of the independent line groups R and L adjacent in the direction in which the line lines La, Lb, Lc, and Ld and the line lines Ra, Rb, Rc, and Rd extend intersect at an angle of 90 degrees if an extended line is drawn. There are strips La, Lb, Lc, Ld of adjacent independent strip groups R, L, strips Ra, Rb, Rc, Rd, and foreign matter does not pass straight through the surface of the cleaning unit main body surface 15. Therefore, the foreign matter enters the cleaning sheet 1 at any position and is entangled. Even when a downward force is applied to the cleaning unit main body surface 15 of the cleaning tool 10, the foreign matter gets into the cleaning sheet 1 and gets entangled by the vertical elastic force and the elastic force between the gaps.

  The plurality of independent line groups R and L of the cleaning sheet 1 of the present embodiment are such that when the reference sheet 2 is transmitted, the independent line groups R and L on the front and back overlap at the same position. Even if an external force is applied to a plurality of independent line groups R, L, one reference line is positioned at about 1/2 the thickness of the line La, Lb, Lc, Ld and the line Ra, Rb, Rc, Rd. Since there is a position of the sheet 2 and it has elasticity, the space surrounded by a plurality of independent filament groups R, L and the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd are Acts as a foreign matter storage area. Also, the reflection of 45 degrees collides with the adjacent stripes having an inclination angle of overlap width δ = + 45 degrees and overlap width δ = −45 degrees, and it is difficult to leave the rectangular reference sheet 2 made of a nonwoven fabric sheet or a woven fabric sheet. Become.

The inventors determine the position of the reference sheet 2 and the interval between the lines on the front and back of the reference sheet 2 at the intermediate positions of the thicknesses of the lines La, Lb, Lc, Ld or the thicknesses of the lines Ra, Rb, Rc, Rd. Is effective, the foreign material enters into the interval between the reference sheet 2 or the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc, Rd, and the elastic force of the non-woven yarn acts. It was determined that the foreign material was held elastically.
However, for example, in the manufacturing apparatus for the cleaning sheet 1 as the functional sheet according to the present embodiment, the spunlace processing unit 23 that uses only the conveyor 21 is used to generate a high-pressure water flow between the reference sheet 2 and the non-woven fibers of short fibers. The cleaning sheet 1 in which fibers are entangled with the reference sheet 2 and the thickness of the filaments La, Lb, Lc, Ld and the thickness of the filaments Ra, Rb, Rc, Rd is formed only on the surface of the reference sheet 2 (only on one side) Produced experimentally.

Here, only the surface of the reference sheet 2 is formed with the lines La, Lb, Lc, Ld and the lines Ra, Rb, Rc, Rd, and the lines La, Lb, Lc, The Ld and the filaments Ra, Rb, Rc, Rd were formed and compared. As a result, there was no significant difference between the two. The independent line group R and the independent line group L were tested in a shape of about 20 mm × 37 mm, and no change in the properties of the cleaning sheet 1 was observed at a size of about 10 mm × 20 mm to about 20 mm × 40 mm.
That is, when the filaments La, Lb, Lc, Ld, filaments Ra, Rb, Rc, Rd are processed by the spunlace method, the filaments La, Lb, Lc, Ld and filaments Ra, Rb, Rc, The density of Rd increases and its mass also increases. Accordingly, the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd are, in other words, bridge girder and are held at the interval between the filaments. , Lb, Lc, Ld, if the foreign matter collides with the filaments Ra, Rb, Rc, Rd, the result is that the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc, Rd are submerged and secured. It was out.

  Briefly, the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc, Rd have a higher density than the reference sheet 2 and its mass increases. Therefore, the filaments La, Lb, Lc, Even when an external force is applied to Ld, filaments Ra, Rb, Rc, and Rd, the amount of change is small. Since the reference sheet 2 is lower in density than the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc, Rd and its mass is also small, the filaments La, Lb, Lc, Ld and the filaments Ra, Rb , Rc, Rd. However, since the density change and mass change of the reference sheet 2 are small, the reference sheet 2 has a dust collecting function for foreign matters. Therefore, if a foreign object collides with or is guided to the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd, it is presumed that the foreign substance will sink into and be secured there.

That is, the rectangular reference sheet 2 made of a nonwoven fabric sheet or a woven fabric sheet is positioned in the thickness direction, and even if it is on dust, hair or solid waste on the floor, it holds them by elasticity, A rectangle made of a nonwoven fabric sheet or a woven fabric sheet that collides with the adjacent filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd having an inclination angle of θ = + 45 degrees and θ = −45 degrees by reflection. It is difficult to move away from the reference sheet 2 in the form of a sheet, and it is normally accommodated in the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd, and the foreign matter retaining property is maintained.
Accordingly, the line La, Lb, Lc, Ld and the line La, Lb, Lc, Ld and the line La, Lb, Lc, Ld and the line La, Rb, Rc, Rd can be lifted to a half height. It was confirmed that the strips Ra, Rb, Rc, and Rd are the core, the reference sheet 2 is slightly lifted, and the movement path of the foreign matter is formed at intervals between the strips.

Therefore, it has been found that the line La, Lb, Lc, Ld and the lines Ra, Rb, Rc, Rd need not be formed on both sides of the reference sheet 2 and may be formed only on one side.
Moreover, in the said embodiment, the short fiber is entangled planarly with the filament La, Lb, Lc, Ld and the filament Ra, Rb, Rc, Rd in what provided the some hole part in the reference | standard sheet | seat 2. Although the process to match was demonstrated, the cleaning sheet 1 was manufactured using the plain sheet 2 non-woven fabric sheet (mat) with a thickness of 1 to 4 mm.

[Embodiment 2]
The manufacturing will be described using another cleaning sheet manufacturing apparatus as a functional sheet shown in the schematic configuration diagram of FIG.
The reference sheet 2 was a non-woven fabric having a thickness of 2 mm calculated by photographing the end portion. In addition, it was confirmed by experiment of a later date that a nonwoven fabric may be sufficient when implementing this invention.
The mask drum 70 formed of the stainless steel plate of the cleaning sheet 1 according to the present embodiment is formed in the shape of the line La, Lb, Lc, Ld, line Ra, Rb, Rc, Rd shown in FIG. It is a mask that is formed as a through hole and forms the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd.
Around the mask drum 70, the guide cylinder 81 and the guide cylinder 82 allow the homogeneous reference sheet 80 (reference sheet 2) to rotate along the periphery of the mask drum 70 from the left to the right in FIG. 8. Is being transported to. Around the mask drum 70, the reference cylinder 80 and the guide cylinder 82 allow the reference sheet 80 to rotate at an equal speed to the outer periphery of the mask drum 70 within an angle range of 200 to 270 degrees.

The end of the mask drum 70 is closed, and a manifold 62 connected to the pipe line 61 is disposed there. The pressure in the pipe 61 and the manifold 62 (not shown) is adjusted by adjusting the pressure of the spunlace nozzle 63 by a pressure regulator (not shown) and adjusting the energy of the spunlace method in which fibers are entangled with the high-pressure water flow between the reference sheet 80 and the pipe 61. The fiber is entangled with the reference sheet 80 with a high-pressure water flow. Thereby, the position and cross-sectional shape of the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc, Rd with respect to the reference sheet 80 are specified.
Below the mask drum 70 is disposed a collection tank 73 that collects excess liquid after the short fibers are entangled with the reference sheet 80 by high-pressure water flow. A stirring filter 74 is connected to the collection tank 73, a necessary amount of short fibers and liquid are mixed, and a fluid composed of the short fibers and liquid is supplied by a pump 76 that circulates the fluid.

  A pump 76 that generates a predetermined pressure passes through the conduit 61 and supplies the manifold 62 with the required amount of short fibers and liquid. A jet spray 63a is constantly sprayed from the spunlace nozzle 63, and the filaments La, Lb, Lc, Ld, the filaments Ra, Rb, Rc are within a predetermined angular range by the short fibers that have passed through the through holes of the mask drum 70. , Rd are formed. At this time, due to the injection from the jet spray 63a, the positions of the filaments Ra, Rb, Rc, Rd and the filaments La, Lb, Lc, Ld are increased in density, the mass thereof is increased, and the mass is relatively high in elasticity. It becomes. As a result, the nonwoven fabric sheet or the woven fabric sheet in the independent filament groups R, L and the filaments Ra, Rb, Rc, Rd and the filaments La, Lb, Lc, Ld has a dense fiber density and a large mass. Therefore, since the fiber density of the nonwoven fabric sheet or the woven fabric sheet can be formed high, the ability to absorb and retain liquid is increased by capillary action.

Accordingly, the mask drum 70 is formed with through holes for forming the filaments La, Lb, Lc, Ld, and the filaments Ra, Rb, Rc, Rd. The fibers are entangled with the reference sheet 80 by a high-pressure water flow between the reference sheet 80 and the non-woven fibers of the short fibers in the spunlace processing section 75 in the mask drum 70, and the filaments Ra, Rb, Rc, Rd or filaments La, Lb, Lc, Ld are entangled.
The figure shown in FIG. 2 is drawn as a through hole in the annular mask drum 70 so that the reference sheet 80 rotates at the same speed as the mask drum 70 along the periphery of the mask drum 70. Furthermore, the guide cylinder 81 and the guide cylinder 82 are moving at a constant speed. That is, the shape of the reference sheet 80 is transferred to the reference sheet 80 around the mask drum 70 because the guide cylinder 81 and the guide cylinder 82 make the reference sheet 80 at the same speed as the outer periphery of the mask drum 70.

Therefore, since the jet spray 63a is sprayed from the spunlace nozzle 63 through the through hole of the mask drum 70, and the fibers are entangled with the reference sheet 80 by the high-pressure water flow between the nonwoven fabric fibers made of short fibers, the filaments Ra, Rb, Rc, The density of only the positions of Rd or filaments La, Lb, Lc, Ld increases, and the mass also increases. At this time, the filaments Ra, Rb, Rc, Rd or the filaments La, Lb, Lc, Ld become a lump, and during that time, due to peeling from the mask drum 70, the mass on the floor side of the reference sheet 80 has a low density. A foreign substance passage with a small amount is formed by the interval between the filaments.
The cleaning sheet 1 as the functional sheet of this embodiment also has the filaments Ra, Rb, Rc, Rd and the filaments La, Lb, Lc, Ld so that the short fibers are intertwined with the reference sheet 80 by high-pressure water flow from one side. Is forming. In addition, the nonwoven fabric sheet or the woven fabric sheet in the independent filament groups R, L and filaments Ra, Rb, Rc, Rd and filaments La, Lb, Lc, Ld has a dense fiber density, Since the fiber density of the nonwoven fabric sheet or the woven fabric sheet can be formed high, the ability to absorb and retain liquid is increased by capillary action.

However, the line Ra, Rb, Rc, Rd in the adjacent independent line group R, L or the virtual straight line MM connecting the lowest ends of the lines La, Lb, Lc, Ld is adjacent to the same line Formed in the overlapping width δ where the imaginary straight lines NN connecting the uppermost ends of the filaments Ra, Lb, Rc, Rd or the filaments La, Lb, Lc, Ld at the shortest distance from the independent filament group NN It is.
Therefore, the line La, Lb, Lc, Ld and the line La, Lb, Lc, Ld and the line La, Lb, Lc, Ld and the line La, Lb, Lc, Ld and the line La The strips Ra, Rb, Rc, Rd are the cores, and the spacing between the streaks of the reference sheet 80 is raised, and foreign matter such as dust on the floor, hair, solid debris, stain stains, adhering liquid, etc. are submerged and held repeatedly, or It was confirmed that floor management such as protection and polishing was performed.
Moreover, in the said embodiment, the short fiber is entangled planarly with the filament La, Lb, Lc, Ld and the filament Ra, Rb, Rc, Rd in what provided the some hole part in the reference | standard sheet | seat 2. Although the process to match was demonstrated, it was confirmed by this experiment that even if a non-woven sheet (mat) is used for the plain reference sheet 80 having a thickness of 1 to 3 mm, the expected characteristics can be secured.

Cleaning sheet 1 as a functional sheet in the above embodiment is further long side 2A of the reference sheet 2,80 to the long side of the cleaning body surface 15 of the cleaning tool 10, a 2B, the cleaning body of the cleaning tool 10 Since the short sides 2C and 2D of the reference sheet 2 and 80 are associated with the short side of the surface 15 and attached, the long sides 2A and 2B of the reference sheet 2 and 80 are attached to the cleaning unit main body surface 15 of the cleaning tool 10. The cleaning tool 10 can be reliably attached to the cleaning unit main body surface 15.

Here, the cleaning sheet 1 as the functional sheet according to the above embodiment is a virtual reference line perpendicular to the two opposite sides 2A and 2B of the rectangular reference sheet 2 and 80 made of a nonwoven fabric sheet or a woven fabric sheet. XX is drawn, and with respect to the drawn virtual reference line XX, the same line thickness and the same line length are inclined at −45 degrees and +45 degrees by the collection of non-woven fibers on the reference sheets 2 and 80. A plurality of independent line groups R and L formed with the same line interval and the same number of lines are formed. Incidentally, the whole of the present invention has an overall conceptual shape as if the four-folded stripes (four-folded) were inclined 45 degrees.
Further, the filaments La, Lb, Lc, Ld or the filaments Ra, Rb, Rc, Rd formed at the inclination angles of −45 degrees and +45 degrees are formed on the opposing long sides 2A, 2B of the reference sheet 2,80. A virtual reference line XX that is perpendicular to the virtual reference line XX is set. The virtual reference line XX is formed by a set of nonwoven fabric fibers on both surfaces of the reference sheets 2 and 80 with respect to the set virtual reference line XX.

  The plurality of independent line groups R and L set a virtual reference line XX perpendicular to two opposite sides (or even one side) of the reference sheets 2 and 80, and the set virtual line Formed with the same line thickness, the same line length, and the same line interval with the inclination of −45 degrees and the inclination of +45 degrees by the collection of nonwoven fabric fibers on the reference sheets 2 and 80 with respect to the reference line XX The filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd are independent of each other.

The plurality of independent line groups R and L of the cleaning sheet 1 as the functional sheet according to the above embodiment are such that when the reference sheets 2 and 80 are transmitted, the front and back line groups overlap silhouette lines at the same position. It is.
Here, since the plurality of independent line groups R and L pass through the reference sheet 2 and 80, the line groups on the front and back are overlapped at the same position (the same on the front and back). Is levitated by the front and back line groups, and is suitable for collecting foreign matters at intervals of the line.

The cleaning sheet 1 as the functional sheet according to the embodiment further includes the long sides 2A and 2B of the reference sheet 2 and 80 on the long side of the cleaning unit main body surface 15 of the cleaning tool 10 and the cleaning unit main body of the cleaning tool 10. The short sides 2C and 2D of the reference sheet 2 are associated with the short sides of the surface 15 and attached.
Here, the cleaning unit main body surface 15 of the cleaning tool 10 is attached with the long sides 2A and 2B of the reference sheet 2 associated with the long sides and the short sides 2C and 2D of the reference sheet 2 associated with the short sides and cleaned. Although the tool 10 is provided, the operator can install it without thinking about it.

    The cleaning sheet 1 as the functional sheet according to the above-described embodiment has the inclinations of −45 degrees and +45 degrees of the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd being ± 15 degrees with respect to each other. It is within the range of the gradient. That is, the inclinations of the filaments La, Lb, Lc, and Ld and the filaments Ra, Rb, Rc, and Rd of −45 degrees and +45 degrees are meaningful for the inclination of 45 degrees, but the inclination ranges of ± 15 degrees with respect to each other. Within the range, it was confirmed that the characteristics were maintained.

[Embodiment 3]
Further, FIG. 9 is basically a plan view of the “three collapsed stripes” of the cleaning sheet of the third embodiment of FIG. 9 when the functional sheet of the present embodiment is viewed from the “breaking stripes”, and the implementation shown in FIG. The configuration of the plan view of the “flanked stripes” of the cleaning sheet of aspect 3 can be expressed as the concept of the invention.
The “breaking stripe” in the present embodiment overlaps between a virtual straight line MM that connects the bottom ends of the independent line groups R and a virtual straight line NN that connects the top ends of the adjacent independent line groups R. The width δ exists. At the same time, there is an overlap width δ between a virtual straight line MM connecting the lowermost ends of the independent line group L and a virtual straight line NN connecting the uppermost ends of the adjacent independent line group L. is there.

  Therefore, for example, foreign matter such as dust on the floor, hair, solid dust, etc., when the cleaning unit main body surface 15 of the cleaning tool 10 is repeatedly reciprocated from the front to the back, the filaments La, Lb, Lc, Ld, the filaments Collides with Ra, Rb, Rc, Rd at a collision angle of 45 degrees, and similarly, the lines La, Lb, Lc, Ld, the filaments with inclination angles of +45 degrees and −45 degrees adjacent to each other by 45 degrees reflection. Collide with Ra, Rb, Rc, Rd. Therefore, the cleaning does not end while leaving foreign matters such as dust, hair, and solid dust on the floor.

  Since the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd having inclination angles of +45 degrees and −45 degrees are provided at inclination angles of +45 degrees and −45 degrees, When the strips La, Lb, Lc, and Ld and the strips Ra, Rb, Rc, and Rd collide with foreign matter, the reflection angle moves to 45 degrees, so that the cleaning sheet 1 of this embodiment becomes a maze. The foreign matter cannot easily come out of the cleaning sheet 1.

  Further, since the reference sheet 2 is positioned between the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd, the filaments La, Lb, Lc, Ld and the filaments Ra, Rb , Rc, Rd maintains the elasticity in the vertical direction, and is held between the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd, so that the foreign matter removed by cleaning is large. In some cases, it is held, and in the case where it is small, it is held in the filaments La, Lb, Lc, Ld or the filaments Ra, Rb, Rc, Rd.

In addition, the nonwoven fabric sheet or the woven fabric sheet in the independent filament groups R, L and the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd has a dense fiber density and a large mass. Since it is configured, the non-woven fabric sheet or the woven fabric sheet can be formed with high fiber density, and the ability to absorb and retain liquid is increased by capillary action. The independent filament groups R, L and the filaments La, Lb, Lc, Ld and the filaments Ra, Rb, Rc, Rd have a dense fiber density and a large mass compared to the reference sheet 2. Or whether the mass is large.
In the above embodiment, a plurality of independent filament groups of the filaments of θ = −45 degrees and θ = + 45 degrees have the same filament thickness, the same filament length, the same filament interval, and the same number of filaments. Formed. However, even if they have an error of 10 to 30%, they cannot be implemented. In carrying out the present invention, the appearance and the like are taken into consideration from the overall balance.

  The functional sheet of the above embodiment is used for floor management such as dust on the floor, hair, solid dust, stain stain, adhered liquid, removal of foreign matters such as adhering liquid, floor protection, polish, etc., and ensures efficient foreign matter. The functional sheet that can be used for the cleaning sheet has been described as an example. However, since the reference sheet and the independent filament group move independently, the water-insoluble nonwoven fabric contains an aqueous solution such as alcohol or sodium hypochlorite. However, it can also be used as a wet tissue (wet towel) as a wet towel, as a wipe for attaching a wet tissue to a station lunch or the like, or as a wipe for a sick person or a person with some physical disability. In addition, sanitary daily necessities such as toilets and toilet seats can be used for sterilization, sterilization, and wiping. Furthermore, it can be used as a product for pet animals. It can also be used as a cosmetic surface for human use.
