Description

  The present invention relates to a wiping fabric for wiping off dirt on a surface of an object (three-dimensional structure, particularly sphere dirt) to give surface gloss.

  The most commonly used tool for polishing the surface to give gloss is a polisher driven by an electric motor. The polisher is roughly divided into a circular polisher buff that rotates or a rectangular polisher buff vibrates. However, both are methods of applying a polishing compound consisting of oils and fats, abrasive grains, etc. in advance to the surface of the object, and polishing while sliding against the buff surface, requiring an extra abrasive such as a polishing compound. Therefore, it is complicated and the cost becomes high.

  In order to quickly and effectively gloss, it is important to properly select the type, pressure, and number of sliding of the polisher buff according to the shape, material, and desired gloss level of the target substance. Among them, the selection of the type of polisher buff is the most important.

  For example, when the target substance is a pachinko ball, there are currently cloth-type polishing and poly-polishing, and there are polishing methods as described below for general cloth polishing. As shown in FIG. 5 (a), a guide rail P3 in which a ball passage P1 having a semispherical cross section corresponding to the size of a pachinko ball is formed, and a cloth belt P5 as an abrasive member mounted on the surface of the guide rail P3. There is known one provided with a conveying belt P7 arranged to face the guide rail P3 and a spring P9 for urging the guide rail P3 in the direction of the conveying belt P7 (see Patent Document 1).

  The cloth belt P5 covers the entire front side of the guide rail P3, and the pachinko ball P11 is held on one side of the pachinko ball P11 by the ball path P1 via the cloth belt P5, and the opposite side is suppressed by the transport belt P7. It is done. In this state, the transport belt P7 is driven in the lifting direction (a direction perpendicular to the paper surface in FIG. 5A), so that the pachinko ball P11 is lifted in the ball path P1 while being polished by the cloth belt P5. Carried in the direction.

  Since the conventional cloth belt P5 is easy to shrink, the cloth belt P5 shrinks in the lateral direction, and the outer one of the ball paths P1 is not covered with the cloth belt P5 as shown in FIG. 5B. Part may occur. As a result, the pachinko ball P11 conveyed through the ball path P1 not completely covered with the cloth belt P5 protrudes from the ball path P1, and the metal side wall is in contact with P13 and is damaged, so that the dirt cannot be removed well. There is. In addition, if the conventional cloth belt gets dirty, the cloth will be clogged with dirt and cannot be wiped further, and the dirt attached to the cloth may be re-transferred to the pachinko ball. . Therefore, it is necessary to frequently wash the cloth belt, but the cloth belt contracts by washing. In addition, since the fabric itself does not have cushioning properties, it is difficult to uniformly contact the pachinko balls, and thus wiping is uneven.

JP 2000-308752 A

  The present invention has been made to solve the above-mentioned problems, and its purpose is to wipe off dirt on the surface of the object without damaging the object to give a surface gloss, and to wipe off and dimension stability over a long period of time. It is an object of the present invention to provide a wiping fabric that can be used without impairing the strength.

The present invention employs the following means as a result of intensive studies to solve the above-mentioned problems.

《Double Russell Knitted Fabric》
The double raschel knitted fabric is knitted by a double raschel knitting machine, and is composed of a front fabric, a lining fabric, and a connecting yarn that connects the front and back fabrics, and is a conventionally known knitted fabric. There are various types of double raschel knitted fabrics as a knitted structure of a front material and a lining material. For example, a knitting yarn knitted with two or more chain knitting yarns, a mesh-like structure having a substantially hexagonal or rhombus-shaped open stitch, or a plain knitted with chain knitting yarns and insertion yarns Some are organized. In the present invention, the mesh-like structure described above is adopted for either one or both of the outer material and the lining material. For example, a mesh-like structure may be employed for the outer material, and a plain structure may be employed for the lining material, or vice versa. Moreover, you may employ | adopt a mesh-like structure | tissue for both a surface material and a lining.

"fiber"
Examples of fibers constituting the three-dimensional fiber structure include polyester fibers such as polyethylene terephthalate, polyamide fibers such as 6,6-nylon and 6-nylon, cellulosic regenerated fibers, polyacrylonitrile fibers, cotton, silk, and wool. Natural fibers and mixed fibers thereof may be mentioned, but polyester fibers are preferred from the viewpoints of heat compression moldability, compression resilience, flexibility and the like.

<Characteristics of three-dimensional fiber structure>
The three-dimensional fiber structure of the present invention preferably has a fabric elongation according to the JIS L 1096 B-1 method of 20 to 50% in both length and width. When the fabric elongation is less than 20%, the cushioning property is deteriorated. When the fabric elongation exceeds 50%, the shape retention becomes worse.

The three-dimensional fiber structure of the present invention preferably has a permeability of 150 cc / cm ² / sec or more as measured by the Frazier method. When the air permeability is less than 150 cc / cm ² / second, the cushioning property is deteriorated.

  The three-dimensional fiber structure of the present invention preferably has a fabric hardness of 40 to 70 mm as measured by the JIS L 1018 cantilever method. When the fabric hardness is less than 40 mm, the cushioning property is deteriorated, and when the fabric hardness is greater than 70 mm, the shape retaining property is deteriorated.

《Connecting thread》
As the connecting yarn used in the present invention, it is preferable to use a multifilament yarn having a fineness of 33 to 110 dtex composed of a yarn having a single yarn fineness of 3 to 6 dtex. If the single yarn fineness is less than 3 dtex, the strength and elastic force of the fiber are weak, so the shape retention may be deteriorated. If it is larger than 6 dtex, the connecting yarn becomes hard and is formed on the surface of the three-dimensional fiber structure. There is a risk of jumping out. Further, if the fineness is less than 33 dtex, the elasticity of the fiber is weak, so that the shape retaining property may be deteriorated. If it is greater than 110 dtex, the texture of the fabric may be cured. When the connecting yarn is a monofilament, it is not preferable because high temperature and high pressure are applied at the time of molding, so that the connecting yarn may be hardened and flexibility may be deteriorated, and the shape retaining property of the fabric may be deteriorated.

  In the present invention, it is preferable to use a multifilament yarn having a fineness of 33 to 110 dtex composed of a yarn having a single yarn fineness of 3 to 6 dtex as the connecting yarn, and the connecting yarn is different even when high temperature and high pressure are applied during molding. Since the ground structures of the front and back are connected at an angle, the pressure is dispersed, the connected yarn is hardly broken, and the compression resilience is excellent. By using multifilament yarns as connecting yarns, the yarns are less likely to harden even when heated compared to monofilament yarns of the same fineness, so that the flexibility of the fabric is less likely to be impaired, and sufficient thickness retention and shape retention And compression resilience can be secured.

The number of the connecting yarn of the present invention is preferably from 1,700 to 2,800 present / inch ^2, particularly preferably in 2000 to 2600 present / inch ^2. When connecting yarn is less than 1,700 / inch ^2, there is a possibility that compression repulsive force and shape retention is impaired, and if larger than 2600 / inch ^2, or stretchability of the fabric is impaired, flexibility There is a risk of damage. The number of connected yarns is obtained by (number of single yarns) × (number of loops (number / inch ² )) × 2 used for the connected yarns.

<Number of loops>
The number of loops in the ground structure of the present invention is preferably 850 to 1400 pieces / inch ² , and particularly preferably 1000 to 1300 pieces / inch ² . The number of loops of the present invention is determined from (course number / inch ² ) × (well number / inch ² ) of the ground texture of the three-dimensional fiber structure. If the number of loops is less than 850 / inch ² , the fabric may have poor compression resilience and shape retention, and sufficient strength may not be obtained. When the number of loops is more than 1400 / inch ² , the gap between the loops is decreased, the fabric becomes harder or heavier, and the stretchability and flexibility may be impaired.

  The thickness of the fabric is preferably 2 to 6 mm. If the thickness is less than 2 mm, the shape retention property is deteriorated, and the compression resilience may be impaired. If it is thicker than 6 mm, the fabric may become heavy or the texture may be deteriorated.

Weight of the three-dimensional fiber structure of the present invention ^is preferably from ^{250g / m 2 ~350g / m 2} , and more preferably in the range of ^{280g / m 2 ~330g / m 2} . If it is less than 250 g / m ² , the shape retention may be impaired, and if it is heavier than 350 g / m ² , the flexibility may be impaired.

The upper bending rod 40 in which the collar portion 41 is integrally formed is connected.

  The pachinko balls that have flowed in from the introduction basket 11 are transported from the lower roller 4 toward the upper roller by the conveyor belt 6 and then discharged from the discharge basket 41. The process of the transport will be described below. The dirt attached to the pachinko balls is wiped off by the frictional force with the cloth belt 21 provided along the guide rail cover 20, and the cleaned pachinko balls are discharged from the discharge basket 41. As shown in FIG. 1, an inclination angle adjusting bolt 12 that adjusts the inclination angle of the introduction rod 11 is attached to the introduction rod 11. The inclination angle adjusting bolt 12 is provided with a spring so that the pachinko balls are smoothly aligned even when an excessive force is applied to the introduction rod 11 by the pachinko balls flowing inside.

  A guide rail cover 20 is attached to the back side of the above-described lifting cylinder body 3 through a support hinge 28 attached to one side of the lifting cylinder body 3 so as to be freely opened and closed. The support hinges 28 are provided at several places in the vertical direction of the feed cylinder body 3. A stopper 25 is attached to the other side surface of the feeding cylinder body 3 by a stopper 26, and the guide rail cover 20 is engaged with the stopper 25 at a position corresponding to the stopper 25. The engaging protrusion 24 is provided. As shown in FIG. 3, the engagement protrusion 24 is attached by sandwiching a rail groove 20 a having a substantially C-shaped cross section integrally formed on the side surface of the guide rail cover 20 between the attachment piece 73 and the flat washer 55. It has been. The engaging protrusion 24 is a stepped screw, and its hexagonal head is slightly turned to loosen the clamping state between the mounting piece 73 and the flat washer 55, thereby moving the rail 20a in the vertical direction. It can be re-fixed at any position. The support hinge 28 is screwed into the screw hole of the mounting piece 29 inserted into the rail groove 20a of the guide rail cover 20 by screwing the thread portion of the mounting screw 38 inserted into the mounting hole of the support hinge 28, thereby supporting the support hinge 28. And the mounting piece 29 are fixed to the guide rail cover 20 so as to sandwich the rail groove 20a of the guide rail cover 20.

  Inside the guide rail cover 20 is mounted a guide rail member 30 formed with ball passages 31a to 31g which are pachinko ball lifting passages. The guide rail cover 20 is provided with a cloth belt fixing / locking member 22 for locking one end of the cloth belt 21 and a tension locking member 23 for pulling and locking the other end of the cloth belt 21 on the back side thereof. A cloth belt roller 37 (see FIG. 2) for guiding the cloth belt 21 in a folded manner is provided at the upper end. The cloth belt 21 locked to the cloth belt fixing / locking member 22 is passed from the lower end of the guide rail cover 20 to the cloth belt roller 37 through the cloth belt insertion side 36 of the guide rail cover 20 and is then pulled to the tension locking member. 23 is pulled and locked.

  Since the guide rail cover 20 is attached to the lifting cylinder body 3 so as to be openable and closable, the attachment of the conveyor belt 6 and the cloth belt 21 to the pachinko ball polishing lifting device 1 is as shown in FIG. This can be done by rotating the guide rail cover 20 around the fulcrum of the support hinge 28 and opening it. In this way, the transport belt 6 and the fabric belt 21 are mounted, and the transport cylinder body 3 and the guide rail cover 20 are locked by the fasteners 25 in a state where the guide rail cover 20 is closed. The cloth belt 21 is maintained in a state of facing. When the guide rail cover 20 is closed and locked by the stopper 25 as described above, a gap is formed between the feed cylinder body 3 and the guide rail cover 20. The size of the locking member 26 can be adjusted by adjusting the fixing position thereof, and the pressure applied to the pachinko balls to be fed can be changed according to the set value. As described above, in the state where the guide rail cover 20 is closed and locked by the stopper 25, the gap between the conveyance belt 6 and the ball paths 31a to 31g, that is, the interval between the pachinko balls is usually 7 to. It is set to about 10 mm.

Further, the number of connecting yarns of this three-dimensional fiber structure was 26.3 pieces / inch ² , and the weight of the three-dimensional fiber structure was 56.34 g / m ² .

  FIG. 7 is a perspective view of the three-dimensional fiber structure obtained as described above. In FIG. 7, reference numeral 81 denotes a surface network structure, 82 denotes a back surface structure, 83 denotes a front / back intermediate layer, and 84 denotes both end ears.

  In addition, the range of 150 dtex / 48f-75dtex / 144f can be employ | adopted for the fineness of a surface, a back surface, an intermediate | middle layer, and an ear | edge part. Further, the density of the front surface, the back surface, the intermediate layer, and the ear portion can be in the range of 20 course / inch to 50 course / inch and 13 loop well / inch to 26 loop well / inch.

  Examples of the soil component adhering to the pachinko balls include hydrocarbon compounds, carboxylates, ester compounds, polysaccharides such as cellulose, inorganic salts, and the like. Therefore, the following experiment was conducted as to how much dirt adhered to the pachinko balls can be removed using the three-dimensional fiber structure produced as described above.

  That is, the three-dimensional fiber structure is attached in place of the cloth belt 21 of the pachinko ball polishing and lifting device 1 shown in FIG. 2, and 33 pachinko balls are polished by the pachinko ball polishing and lifting device. The dirt adhering to the balls was compared with the dirt adhering to the 33 pachinko balls before being polished by the pachinko ball polisher. The ATP value was measured as a numerical value serving as an index of the dirt. ATP (adenosine triphosphate) is an essential energy substance for all living organisms and is contained in soils derived from microorganisms and organisms. Therefore, by measuring the amount of AMP (adenosine monophosphate) produced by the decomposition of ATP and ATP contained in the wiping fabric, the contamination status can be objectively grasped. For example, a luminescent reagent containing firefly luciferase, luciferin, and pyruvate orthophosphate dikinase (PPDK) is used. Firefly luciferase has a phenomenon that it emits light in the presence of ATP and luciferin. By converting the AMP generated at that time into ATP again using PPDK, the light emission amount corresponding to the total amount of ATP can be obtained with the above-mentioned light emission reagent. By measuring the amount of luminescence with a specific measuring instrument, the degree of contamination can be grasped.

  Specifically, 33 pachinko balls are spread on the bottom of a 500 cc beaker, 30 g of ultrapure water is poured into the beaker, and ultrasonic treatment with a frequency of 40 kHz and an output of 40 W is applied to the ultrapure water in the beaker. Applied for 20 minutes. Then, ultrapure water in the beaker is caused to emit light by reaction with a luminescent reagent containing firefly luciferase, luciferin, and PPDK, and the amount of luminescence is measured by a luminescence measuring instrument (for example, trade name “Lumi” manufactured by Kikkoman Biochemifa). Tester PD-20 "). The ATP value obtained by performing the ultrasonic cleaning on the 33 pachinko balls before polishing with the pachinko ball polishing and lifting device was 2018 (RLU: relative light unit), but the pachinko ball polishing and lifting device The ATP value obtained by performing the above ultrasonic cleaning on 33 pachinko balls before polishing with 536 was 536 (RLU). The smaller the ATP value, the smaller the dirt, so it can be seen that the pachinko ball dirt is improved by polishing with the pachinko ball polishing and lifting device.

  The wiping fabric of the present invention is suitable as a means for wiping off the surface of the three-dimensional structure.
