Description

  The present invention relates to an industrial wipe having an emboss.

Industrial wipes are used for wiping off dust, dirt, moisture, oil, and the like adhering to various industrial products and parts used therefor.
Industrial wipes are required to have less paper dust (sometimes referred to as lint) generated from industrial wipes in addition to wiping performance of moisture and oil, etc. Some industrial wipes on which base paper is laminated have embossed surfaces.
Typical embossing applied to industrial wipes is pin-shaped embossing and dimple-shaped embossing. FIG. 4 shows an industrial wipe in which pin-shaped embossing is applied in a dot shape, and FIG. 5 shows a dimple. Fig. 2 shows an industrial wipe with dot embossing on its shape.

Industrial wipes with pin-shaped embossing are pressure-resisted by a large number of pin-shaped embosses, so that ply peeling is prevented, and dust and dust are efficiently stored in the recesses formed by a large number of pin-shaped embosses. be able to. However, industrial wipes with pin-shaped embossing have poor wiping performance such as grease with high viscosity.
On the other hand, industrial wipes with dimple-shaped embossing can efficiently accommodate high-viscosity grease or the like in a recess having a relatively large aperture formed by dimple-shaped embossing. However, industrial wipes with dimple-shaped embossing have poor wiping performance with low viscosity water and the like, and there is a risk that ply peeling will occur due to being pressured by a relatively small number of dimple-shaped embossing (patent) Reference 1).
In addition to pin-shaped embossing and dimple-shaped embossing, various shapes of embossing have been proposed (Patent Documents 2 to 4).

Moreover, since the longitudinal direction length of the hexagonal emboss is as long as 125 to 200% with respect to the length in the width direction, and the depth of the concave portion of the hexagonal emboss is 0.8 to 1.7 mm, the wiping property is high. .
Furthermore, the long side of the hexagonal emboss does not face the long side of the adjacent hexagonal embossing, and the corner of the long side of the hexagonal embossing faces the corner of the long side of the adjacent hexagonal embossing. Therefore, the contact between the corners of the long sides of the hexagonal embosses and the long sides of the hexagonal embosses, which are so-called sharp corners of the hexagonal embosses, and dust, grease, water, etc. is high, and the wiping property is high.

  Since the crossing angle between the extending direction of the lattice pattern and the lateral direction of the base paper is 0 to 80 degrees, the embossing which is an acute angle portion of the sliding direction of the industrial wipe (horizontal direction and vertical direction) and the lattice pattern The slope is inclined and the wiping property is high.

An industrial wipe characterized in that the crossing angle between the longitudinal direction of the hexagonal embossing and the lateral direction of the base paper is 30 to 60 degrees.

(Function and effect)
In the reference invention of the present invention, since the industrial wipe has a thickness of 1000 to 1700 μm, the water absorption amount of water having a low viscosity is large.
If the thickness is 1000 μm or less, the amount of water absorption is reduced by about 10%. On the other hand, if the thickness of the industrial wipe is 1700 μm or more, the rigidity is increased, which may cause resistance when the industrial wipe is folded in four.

The length in the longitudinal direction of the hexagonal emboss is as long as 125 to 200% with respect to the length in the width direction, and the depth of the concave portion of the hexagonal emboss is 0.8 to 1.7 mm.
In particular, since the length in the longitudinal direction of the hexagonal emboss is as long as 125 to 200% of the length in the width direction, the volume of the recess formed by the hexagonal embossing is larger than that of the regular hexagonal embossing, and the viscosity is high. The wipeability with respect to grease etc. can be improved.
Moreover, since the depth of the recessed part of a hexagonal emboss is 0.8-1.7 mm, the retainability of the dust collected by the recessed part of a hexagonal embossed, water with a low viscosity, etc. is high.

  The long side of the hexagonal emboss is not facing the long side of the adjacent hexagonal emboss, and the corner of the long side of the hexagonal embossing is facing the corner of the long side of the adjacent hexagonal embossing. Therefore, the contact between the corners of the long side of the hexagonal embossing and the long side of the hexagonal embossing, which is a so-called acute angle part of the hexagonal embossing, and dust, grease, water, etc. is large, and the wiping property is high.

Since the crossing angle between the longitudinal extension direction of the hexagonal embossing and the lateral direction of the base paper is 30 to 60 degrees, the sliding direction of the industrial wipe (lateral direction, vertical direction) and the hexagonal embossing The long side of the hexagonal embossing, which is a so-called acute angle portion, is inclined and the wiping property is high.

Hereinafter, an embodiment (reference embodiment) of a reference invention related to the present invention and an embodiment of the present invention will be described in this order.
Reference form
Hereinafter, embodiments of the reference invention as the basis of the present invention will be described. The industrial wipe 1 of the first embodiment has a four-ply structure in which four thin base papers are laminated with hexagonal embosses 2. FIG. 1 shows an emboss pattern of an industrial wiper 1, and FIG. 2 is an enlarged view of the AA cross section of FIG. 1.

<Base material paper>
The base paper 10 constituting the industrial wipe 1 is formed by laminating four thin base papers having a thickness of about 100 μm, and the thickness at the time of lamination is about 400 μm.
By making the base paper 10 into a laminated structure, the industrial wipe 1 has a ply structure, and the risk of the industrial wipe 1 being broken during wiping can be suppressed.
In addition, there is no restriction | limiting in particular about the number of the thin base paper laminated | stacked, However, 2-4 sheets are suitable. When the number of thin base papers is 5 or more, there is a possibility that the laminated portion may be displaced during wiping use, so that wrinkles are generated on the surface of the industrial wipe 1, and the wiping property may be deteriorated.

The thin base paper forming the base paper 10 contains 10 to 30% by weight of LUKP, LBKP (hardwood kraft pulp) and 70 to 90% by weight of NUKP, NBKP (conifer kraft pulp) as pulp, in particular, LUKP, As LBKP, it is preferable to contain pulp produced from FSC certified chips.
The production of the thin base paper can be carried out based on the production of known crepe paper and thin paper from a paper making raw material containing NBKP, LUKP, LBKP, and NUKP.
Examples of constituent fibers other than NBKP and LBKP include non-wood pulp such as kenaf pulp and manila hemp, and synthetic fibers such as polyester fiber, rayon fiber and acrylic fiber.
The basis weight (JIS P 8124: 1998) of each thin base paper is 15 to 25 g / m ² , and preferably 18 to 23 g / m ² .
When the amount is 15 g / m ² or less, it is difficult to speak a sufficient liquid absorption amount. When the amount is 25 g / m ² or more, the rigidity is increased, and the base paper in which four thin base papers are laminated. When the industrial wipe 1 composed of 10 is folded in four, there is a risk of large resistance, and in particular, it may be difficult to wipe the fine parts and the groove portions of the parts.

<Hexagonal embossing>
The base paper 10 is laminated by pressing four thin base papers with the hexagonal emboss 2. The hexagonal emboss 2 formed on the base paper 10 has a longitudinal length (EL) of 4.5 mm, a width direction length (EW) of 3 mm, a depth (ED) of 1.1 mm, and a taper angle (Eθ). ) Is formed at 60 degrees.
Further, when the hexagonal emboss 2 is formed, the thickness (T) of the base paper 10 that is the thickness of the industrial wipe 1 is 1195 μm, and the density is 66 g / cm ³ .
In this specification, the depth (ED) refers to the distance from the surface of the base paper 10 to the bottom surface of the recess 3 of the hexagonal emboss 2, and the taper angle (Eθ) refers to the hexagonal emboss 2. The thickness (T) refers to the distance from one surface of the base paper 10 to the other surface. (See Figure 2)
Furthermore, the thickness (T) of the base paper 10 is measured with a peacock manufactured by Ozaki Seisakusho, and the density is preferably ³⁰ to 80 g / cm ³ from the viewpoint of water absorption and tensile strength.

  Although there is no restriction | limiting in particular about the longitudinal direction length (EL) of the hexagonal embossing 2, 3-9 mm is suitable, and it is more suitable to set it as 125-200% with respect to the width direction length (EW). is there. In addition, when the length in the longitudinal direction (EL) is 3 mm or less, there is a possibility that sufficient wiping properties such as grease with high viscosity cannot be secured, and when it is 9 mm or more, the base paper 10 may be broken at the time of wiping. .

  Although there is no restriction | limiting in particular about the width direction length (EW) of the hexagonal embossing 2, 2-5 mm is suitable. In addition, when width direction length (EW) is 2 mm or less, there exists a possibility that wiping property, such as grease with high viscosity, cannot fully be secured, and in the case of 5 mm or more, there is a possibility that the base paper 10 may be broken at the time of wiping. .

  Although there is no restriction | limiting in particular about the depth (ED) of the hexagonal embossing 2, 0.8-1.7 mm is suitable. In addition, when the depth (ED) is 0.8 mm or less, there is a possibility that sufficient wiping properties such as grease with high viscosity cannot be secured. When the depth (ED) is 1.7 mm or more, the base paper 10 may be broken at the time of wiping. There is.

  The taper angle (Eθ) of the hexagonal emboss 2 is not particularly limited, but is preferably 40 to 65 degrees. If the taper angle (Eθ) is 40 degrees or less, the periphery of the recess 3 of the hexagonal emboss 2 may be dull and there is a risk that sufficient wiping properties such as grease with high viscosity cannot be secured. There is a possibility that the paper 10 is broken at the time of wiping.

The thickness (T) of the base paper 10 is not particularly limited, but is preferably 1000 to 1700 μm, more preferably 1050 to 1700 μm, and is arbitrarily set by pressurization when forming the hexagonal emboss 2. can do.
In addition, when the thickness (T) is 1000 μm or less, the absorption amount is reduced by about 10%, and when it is 1700 μm or more, the rigidity is increased, and there is a fear that a large resistance may be caused when the industrial wipe 1 is folded in four. In particular, it may be difficult to wipe the fine parts and the groove portions of the parts.

Each hexagonal emboss 2 is formed such that the long side 4 of the hexagonal emboss 2 is shifted in the longitudinal direction with respect to the long side 4 of the adjacent hexagonal emboss 2, and The corners 5 are formed at positions facing the corners 5 on both sides of the long side 4 of the adjacent opposing hexagonal emboss 2.
Each hexagonal emboss 2 is formed in a turtle shell pattern at a position where the longitudinal pitch (PL) is 6 mm and the widthwise pitch (PW) is 3 mm with respect to the adjacent hexagonal emboss 2.

Although there is no restriction | limiting in particular about the longitudinal direction pitch (PL) of the hexagonal embossing 2, 4-10 mm is suitable. Further, the width direction pitch (PW) of the hexagonal emboss 2 is not particularly limited, but is preferably 2 to 5 mm.
When the hexagonal emboss 2 is formed in a turtle shell pattern at a position where the longitudinal pitch (PL) is 6 mm and the width direction pitch (PW) is 3 mm, the surface area of the base paper 10 (industrial wipe 1) is hexagonal embossed. Since the surface area before forming 2 is increased to 144%, the wiping property is remarkably improved.
The surface area can be simply calculated by squaring the cross-sectional elongation rate generated when the hexagonal emboss 2 is elongated in the direction perpendicular to the long side 4 of the hexagonal emboss 2 with a tensile force of 1000 CN / 25 mm. 121%.
When the cross-sectional elongation rate is calculated by squaring, the surface area of the industrial wipe after forming the hexagonal emboss is 110 to 110 from the viewpoint of wiping performance with respect to the surface area of the industrial wipe before forming the hexagonal emboss. 130% is preferred.
The bottom of the recess 3 of the hexagonal emboss 2 is flat, and the surface area formed by the recess 3 of the hexagonal emboss 2 is 58% of the surface area of the base paper 10. The formed surface area is preferably 30 to 80% with respect to the surface area of the base paper 10 from the viewpoint of the wipeability of grease having a particularly high viscosity.

The extending direction of the long side 4 of the hexagonal emboss 2 formed in a turtle shell pattern is formed such that the crossing angle (θ) with respect to the lateral direction of the base paper 10 (industrial wipe 1) is 45 degrees.
The crossing angle (θ) is not particularly limited, but when wiping while wiping the industrial wipe 1 in the horizontal direction or the vertical direction, it is an acute angle portion of the hexagonal emboss 2 and the long side 4 is in the sliding direction. When tilted, the wiping property is improved, so 30 to 60 degrees is preferable.
Furthermore, the longitudinal direction is a direction along the flow direction of the base paper 10 at the time of papermaking and is referred to as an MD direction, and the lateral direction is a direction orthogonal to the longitudinal direction and may be referred to as a CD direction.

The hexagonal embossing 2 can be formed, for example, by passing the base paper 10 between a pair of embossing rolls. In particular, it is preferable to use steel match embossing from the viewpoint of making the hexagonal embossing 2 bulky. is there.
In this case, it is suitable that the embossing pressure is 10 to 80 kgf / cm ² , preferably 10 to 25 kgf / cm ² . If the embossing pressure is 10 kgf / cm ² or less, the peripheral part including the long side 3 of the hexagonal emboss 2 cannot be made acute, and the wiping property may be lowered. If the embossing pressure is 80 kgf / cm ² or more, the hexagonal embossing There is a possibility that the base paper 10 is broken during the formation of 2.
With respect to the pair of embossing rolls, a combination of a metal roll and an elastic roll with a hexagonal embossing 2 provided with a turtle shell pattern is preferable. In this case, the elastic roll preferably has a Shore hardness of A30 to A90 on the surface thereof. When the Shore hardness is A30 or less, that is, when the elastic roll surface is soft, the base paper 10 may be broken. When the Shore hardness is A90 or higher, that is, when the elastic roll surface is hard, the hexagonal emboss 2 is formed on the base paper 10. There is a possibility that the thin base paper constituting the base paper 10 cannot be laminated.
The base paper 10 on which the hexagonal emboss 2 is formed as described above is laminated and folded or wound up by an interfolder or the like according to a known method to obtain a product.
Although the hexagonal embossing has been described above, it goes without saying that even if it is a pentagonal or heptagonal embossing, any embossing having equivalent performance may be used.

[Embodiment of the present invention]
Next, an embodiment of the present invention will be described. In the industrial wipe 1 according to the embodiment of the present invention, hexagonal embosses 2 are formed in a tortoiseshell pattern on each lattice portion 8 of the linear embosses 6 and 7 formed in a lattice pattern.
FIG. 3 shows an emboss pattern of the industrial wiper 1 according to the embodiment of the present invention. Since the hexagonal emboss 2 and the base paper 10 are the same as those in the above reference embodiment, the description thereof is omitted.

<Linear embossing>
The straight embosses 6 and 7 forming the lattice pattern have a width (LW) of 2 mm and a depth (LD) of 1.1 mm, and are defined by the diagonal distance of the lattice portion 8 surrounded by the linear emboss 6. The pitch (LP) is 19 mm, and the lattice pattern has an intersecting angle of 45 degrees with respect to the horizontal direction of the base paper 10.
When the lattice pattern is used, when moisture or the like having a low viscosity is wiped off, the moisture or the like progresses while being diffused and absorbed in the recesses of the linear emboss 6, thereby improving the ability to wipe off moisture or the like having a low viscosity.

Although there is no restriction | limiting in particular about the width | variety (LW) and depth (LD) of the linear embossing 6 and 7, 1-3 mm is suitable from a viewpoint of wiping off.
Moreover, there is no restriction | limiting in particular about emboss pitch (LP), However, 10-30 mm is suitable from a viewpoint of wiping off property, and 15-25 mm is more suitable.

The area composed of the straight embosses 6 and 7 is preferably 2 to 40% with respect to the surface area of the base paper 10, and more preferably 10 to 20%. When the area of the linear embosses 6 and 7 is 2% or less, when the area is 40% or more, it is difficult to achieve a desired wiping property.
The lattice pattern has an intersection angle of 45 degrees with respect to the horizontal direction of the base paper 10. That is, an intersection angle (Lθ1) between the extending direction of one linear emboss 6 forming the lattice pattern and the lateral direction of the base paper 10 is 45 degrees, and the other linear shape forming the lattice pattern is formed. Similarly, the crossing angle (Lθ2) with respect to the extending direction of the emboss 7 and the lateral direction of the base paper 10 is 45 degrees.
Although there is no restriction | limiting in particular about intersection angle (L (theta) 1, 2), 30 to 60 degree | times is suitable from a viewpoint of wiping off.

  In the industrial wipe 1 according to the embodiment of the present invention, as shown in FIG. 3, the hexagonal emboss 2 formed on each lattice portion 8 has the base paper 10 extending in the long side 6 of the hexagonal emboss 2. However, the extending direction of the long side 6 of the hexagonal emboss 2 may be formed with an intersecting angle of 30 to 60 degrees with respect to the lateral direction of the base paper 10. .

The method of forming the linear embosses 6 and 7 and the hexagonal embossing 2 can be formed, for example, by passing the base paper 10 between a pair of embossing rolls. In particular, the linear embossing 6 and 7 and the hexagonal embossing 2 are bulky. It is preferable to use steel match embossing from the viewpoint of making it.
In this case, it is suitable that the embossing pressure is 10 to 80 kgf / cm ² , preferably 10 to 25 kgf / cm ² . If the embossing pressure is 10 kgf / cm ² or less, the peripheral part including the long side 3 of the hexagonal emboss 2 cannot be made acute and the wiping property may be lowered. If the embossing pressure is 80 kgf / cm ² or more, the linear embossing There is a possibility that the base paper 10 is broken when the 6, 7 and hexagonal embosses 2 are formed.
Regarding the pair of embossing rolls, a combination of a metal roll and an elastic roll in which the linear embossments 6 and 7 are provided with a lattice pattern and the hexagonal embossing 2 is provided with a turtle shell pattern is preferable. In this case, the elastic roll preferably has a Shore hardness of A30 to A90 on the surface thereof. When the Shore hardness is A30 or less, that is, when the elastic roll surface is soft, the base paper 10 may be broken. When the Shore hardness is A90 or more, that is, when the elastic roll surface is hard, linear embossing 6 and 7 and hexagonal embossing 2 cannot be formed on the base paper 10, and there is a possibility that the thin base paper constituting the base paper 10 cannot be laminated.
The base paper 10 on which the linear embosses 6 and 7 and the hexagonal emboss 2 are formed as described above is laminated and folded or wound by an interfolder or the like according to a known method to obtain a product.

The sample (dimensions: 315 mm wide × 405 mm long) was folded in four and slid on the horizontal table for about 5 seconds with a 500 g weight placed thereon, and then the remaining state of the grease was visually evaluated.
In addition, it was set as "(double-circle)" which grease was able to wipe off well, "(circle)" which grease wiped off normally, and "(triangle | delta)" which grease did not wipe off.
<Tensile strength>
Evaluation was performed according to JIS P8113.
The tensile strength [CN / 25 mm] is “◎” when 5000 or more, “◯” when 3500 to 5000, “Δ” when 2000 to 3500, and “x” when 2000 or less.

As shown in Table 1, Reference Examples 1 to 6 were highly evaluated for water absorption, wiping properties, and tensile strength, while Comparative Example 1 had a low evaluation of water absorption, and Comparative Example 2 had a water absorption. The evaluation of wiping property was low.
From the above, it was confirmed that the industrial wipe according to the present invention was excellent in water absorption, wiping property and tensile strength.
