Description

  The present invention relates to a wiper that wipes off water or oil adhering to a wiping surface.

  The wiper wipes off water or oil adhering to the wiping surface of a device or instrument installed in a clean room or the like. Conventionally, a wiper as disclosed in Patent Document 1 has been known as such a wiper.

  As shown in FIG. 4, the wiper 100 includes an absorbent body 103 having liquid absorbability, a surface material 101 disposed on the surface of the absorber 103, and a back surface material 102 disposed on the back surface of the absorber 103. I have. Such a wiper 100 is usually formed in a square shape.

Further, the wiper 100 has different liquid absorbency (liquid retention) and wiping property on the front and back surfaces due to different fiber states on the front and back surfaces. Specifically, the performance of the front and back surfaces of the wiper 100 differs because the surface material 101 is formed from a hydrophilic nonwoven fabric and the back material 102 is formed from a non-hydrophilic nonwoven fabric. Therefore, in order to perform good wiping, it is necessary to identify the front and back surfaces of the wiper 100.
JP-A-11-28182

  However, the wiper 100 as described above has a problem that it is difficult to grasp the difference between the front and back surfaces by visual observation, and the front and back surfaces cannot be identified at a glance.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a wiper that can reliably identify the front and back surfaces.

  The object of the present invention is a rectangular wiper having at least one of liquid-absorbing property, liquid-retaining property or wiping property on the front and back surfaces, and a front / back identification portion formed so as to cut out one corner portion. Achieved with a wiper having

  Moreover, in the said wiper, it is preferable that the said front and back identification part is the shape which cut off the said corner part in the diagonal direction at linear form.

  According to the wiper of the present invention, the front and back surfaces can be reliably identified.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a top view of a wiper according to an embodiment of the present invention.

  As shown in FIG. 1, the wiper 1 is formed of a rectangular knitted fabric having front and back surfaces, and has a front and back identification side 4 formed so as to cut out one of the rectangular corner portions 2. is doing. The wiper 1 includes short sides 3 and 3 and long sides 5 and 5 that face each other, and is cut out in a straight line from one short side 3 toward the adjacent long side 5 to form one corner. The part 2 is formed in a missing shape. The front / back identification side 4 is preferably linear from the viewpoint of workability. Further, the front / back identification side 4 is inclined with respect to the short side 3 and the long side 5 by cutting away the rectangular corner portion 2 in an oblique direction. The lengths of the short side 3 and the long side 5 can be appropriately changed according to the purpose of use of the wiper 1.

  Materials used for the wiper 1 include natural fibers such as cotton and hemp, synthetic fibers such as polyester, nylon, and acrylic, regenerated fibers such as rayon and cupra, and natural fibers, synthetic fibers, and regenerated fibers. In this embodiment, polyester is used.

  The wiper 1 has different fiber states on the front and back surfaces. This is because, in the process of manufacturing the wiper 1, differences occur in the gaps between the fibers on the front and back surfaces, entanglement, and the like, resulting in differences in fiber density and structure. Thereby, at least one of liquid absorption property, liquid retention property, or wiping property differs in the front and back of the wiper 1. For example, when the wiper 1 is manufactured from polyester, the amount of liquid absorption due to the capillary phenomenon differs due to the difference in fiber density on the front and back surfaces, resulting in a difference in liquid absorption. Moreover, since the contact state of a wiping surface and a fiber changes with the difference in the density of a fiber, a difference arises in wiping property. Further, the wiping property varies depending on the knitting direction on the front and back surfaces. In the present embodiment, the surface of the wiper 1 is superior in liquid absorbency and wiping performance compared to the back surface. Further, the strength and the like may be different between the front and back surfaces of the wiper 1.

  About the liquid absorptivity of the front and back of the wiper 1, it can measure according to the test (birec test) prescribed | regulated to JIS-L-1907, for example. Moreover, about liquid retention, it can measure according to the test prescribed | regulated to JIS-L-1912, for example. Further, the wiping property can be measured according to, for example, a wiping property test described in JP-A-2007-40792.

  FIG. 2 is an enlarged view of the front surface of the wiper 1, and FIG. 3 is an enlarged view of the back surface of the wiper 1. As shown in FIGS. 2 and 3, the density and structure of the fibers are different between the front and back surfaces of the wiper 1.

  Next, a method for identifying the front and back surfaces with the wiper 1 having the above configuration will be described.

  First, as shown in FIG. 1, the wiper is such that the short side 3 is parallel to the horizontal direction (X-axis direction in FIG. 1) and the long side 5 is parallel to the vertical direction (Y-axis direction in FIG. 1). 1 is placed. Further, the wiper 1 is arranged so that the front / back identification side 4 faces upward (the positive direction of the Y axis in FIG. 1). At this time, the front / back identification side 4 is arranged to face the left side of the paper (the negative direction of the X axis in FIG. 1). In this state, the surface of the wiper 1 is located on the upper surface of the paper (the front side of the paper). Further, the rear surface of the wiper 1 is located on the lower surface of the paper (the back side of the paper). Thereby, it can be identified which direction the front and back surfaces of the wiper 1 are facing.

  Contrary to the above, when the front / back identification side 4 is arranged so as to face rightward on the paper (the positive direction of the X axis in FIG. 1), the wiper 1 is turned over, and the surface of the wiper 1 is The lower surface of the paper surface (the back side of the paper surface) is located, and the back surface of the wiper 1 is positioned on the upper surface of the paper surface (the front side of the paper surface). Thereby, it can be identified which direction the front and back surfaces of the wiper 1 are facing.

  As described above, according to the wiper 1 according to the present embodiment, the liquid-absorbing property and the wiping property are different between the front and back surfaces, and the front and back identification sides formed so as to cut out one of the rectangular corner portions 2. 4, the front and back surfaces of the wiper 1 can be reliably identified by recognizing the positions of the front and back identification sides 4 when the rectangular short side 3 and the long side 5 are arranged in a predetermined direction.

  As mentioned above, although one Embodiment of this invention was described, the specific aspect of this invention is not limited to the said embodiment.

  For example, in the above embodiment, the wiper 1 is configured from a knitted fabric, but is not limited thereto as long as the liquid absorption or wiping properties of the front and back surfaces are different. The wiper 1 is configured from a woven fabric, a nonwoven fabric, or a combination thereof. It may be.

  In the above embodiment, the front / back identification side 4 is linear, but this shape is not particularly limited as long as one of the rectangular corners 2 is cut off, and may be curved. Good.

  Moreover, the usage method of the wiper 1 is not particularly limited. For example, the wiper surface is wiped dry with the wiper 1 in a dry state, or the wiper 1 itself is preliminarily impregnated with a liquid and then wiped with the wet wiper 1. The surface can be wiped off. Examples of the liquid impregnated in the wiper 1 include alcohols such as ethanol, organic solvents such as toluene, or pure water.

It is the figure which looked at the wiper concerning one embodiment of the present invention from the top. It is an enlarged view of the surface of a wiper. It is an enlarged view of the back surface of a wiper. It is a perspective view of the conventional wiper.
