[Prior art]
Generally, in a patterned polishing tool, the polishing portion at the tip has two types of modes, such as a brush mode or a non-brush mode such as a scourer or a sponge.
When this is used for cleaning, the former has good drainage and abrasion, but has a hard lump due to the rigidity of the individual polishing brush fibers and cannot enter a narrow space, causing a problem in cleaning workability. . Further, since a large number of needle-like fine brush fiber aggregates are handled, it is not easy to fabricate the attachment to the handle.
Since the latter usually forms a single mass, it can be easily mounted on a handle or the like, but the drainage is poor and the polishing and cleaning action is not as effective as a brush.

Although the present abrasive nonwoven fabric is known, the configuration, characteristics, and the like of the nonwoven fabric are as follows.
As the base material of the abrasive nonwoven fabric, a nonwoven fabric made of entangled fibers of synthetic resin fibers having a fine diameter is used, and exhibits a predetermined elasticity by maintaining a constant thickness. Demonstrate. According to the present substrate, water repellency is basically used. However, exceptional non-water repellency is not excluded, and the substrate may have hydrophilicity.
Abrasive grains are bonded to the non-woven fabric by a predetermined processing method using a thermosetting resin as a binder resin. The attachment of the abrasive grains is based on the attachment to the surface layer of the nonwoven fabric, but does not exclude the attachment to the interior of the nonwoven fabric.
In the above, acrylic fibers, polyamide fibers, polyester fibers, polyolefin fibers, and the like are appropriately adopted as synthetic resin fibers used for the base material. In terms of fineness, a fineness near 15d (denier) and 1 to 50d is adopted. Known abrasive grains are used, and for example, alumina, diatomaceous earth, silica, calcium carbonate, calcium phosphate, carborundum, gold sand, glass beads, mica and the like are appropriately adopted. The size and shape of the abrasive may be appropriately set according to the intended use, and the size is 0.5 μm or more and 100 μm or less. As the binder resin, a thermosetting resin such as an ethylene-vinyl acetate resin, an acrylic resin, or a urethane resin is appropriately adopted. The abrasive grains are fixed to at least the surface layer of the nonwoven fabric using a binder resin. As the fixing method, an abrasive method is mixed with a binder resin, and an impregnation method, a coating method, a spray method, a dot method and the like are appropriately adopted.
The abrasive nonwoven fabrics 5A and 5B are easily bent by a person's hand or fingertip as a characteristic of hardness and elasticity, and immediately return to the original state when released.
[0017]
(Twist processing)
As shown in FIG. 4 and FIG. 5, two disc-shaped, non-abrasive nonwoven fabrics 5A, 5B of a predetermined thickness are stacked, and two steel metal wires 7, 8 are radially interposed therebetween.

The pitch is a small pitch of, for example, 1.5 cm.
Thereafter, at the end of the handle portion 2, in other words, at the place where the polishing portion 1 starts, the metal wires 7 and 8 sandwich the disc-shaped abrasive nonwoven fabrics 5 </ b> A and 5 </ b> B with a predetermined tightening force and twist at a gentle pitch. Can be In the present embodiment, the metal wires 7 and 8 are twisted at 180 ° from the start point to the end point of the disc-shaped abrasive nonwoven fabrics 5A and 5B. At this time, the tightening force (compression force) of the two metal wires 7, 8 on the abrasive nonwoven fabrics 5A, 5B corresponds to the strength of the abrasive nonwoven fabrics 5A, 5B, and the strength at which the abrasive nonwoven fabrics 5A, 5B do not break. Is set to
FIG. 6 shows the metal wires 7, 8 in this state. α indicates the interval between the metal wires 7 and 8 and maintains substantially the same distance from the start point to the end point of the abrasive nonwoven fabrics 5A and 5B.
As the metal wires 7 and 8 are twisted, the two abrasive nonwoven fabrics 5A and 5B are twisted and separated from each other at 90 ° intervals, and the polishing leaves 5 are formed at equal intervals with the same phase of twist.
In other words, in the abrasive nonwoven fabrics 5A and 5B, a large stress (compressive stress) is introduced in the portion where the stranded wires 7 and 8 are sandwiched and in the immediate vicinity thereof, and the stress is gradually reduced in other portions. The abrasive 5 keeps a predetermined twisted state.

A description will be given of the operation of the polishing tool K with the handle and the operation thereof. The polishing tool K with a handle is used as a polishing tool suitable for polishing and cleaning in water.
FIG. 7 shows the polishing operation of the polishing section 1. In the figure, H denotes an object to be cleaned, I denotes dirt adhering to the object H to be cleaned, and W denotes water.
An operator grips the grip portion 3 and applies the polishing portion 1 to the surface of the cleaning target H, and rubs the polishing leaf 5 of the polishing portion 1 against the cleaning target H to perform cleaning. At this time, since the polishing leaves 5 of the polishing section 1 are flexible, they easily spread between the two polishing leaves 5, and the side surface 5b of the polishing leaves 5 comes into contact with the surface of the cleaning object H with a wide contact surface S. I do. That is, the contact width of the polishing leaf 5 increases due to the twist.
The illustrated example shows a case in which the pressing force of a normal worker is used. By further applying the force, the contact surface S is expanded against the elasticity of the polishing leaf 5 and the gap space is eliminated.
In this state, the gripper 3 is pushed forward and pulled rearward (back and forth operation), and the polishing unit 1 is moved back and forth (perpendicular to the paper). The dirt ■ adhered to the surface of the cleaning object H is polished by the polishing leaves 5 and is separated and removed from the surface of the cleaning object H. More specifically, the dirt ■ is scraped off by the abrasive nonwoven fabric and taken into the abrasive nonwoven fabric. By adding a lateral movement to the front-back movement of the gripper 3, in other words, a circular movement, the polishing unit 1 uniformly contacts the surface of the object H to be cleaned.
[0020]
According to the patterned polishing tool K of the present embodiment, when the polishing section 1 is immersed in the water W, the polishing leaves 5 are slender in the movement of the polishing section 1 so that the water resistance is small and V The grooves facilitate drainage, and the cleaning operation is performed smoothly without causing splashing of the washing water.
In addition, since the polishing leaves 5 of the polishing section 1 have flexibility, the polishing tool K with a handle can easily enter a narrow gap and perform a cleaning operation.
Furthermore, if the abrasive solution 5 is used by immersing the detergent solution in the polishing leaf 5, a more effective cleaning operation can be performed.
