Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cloth made of the pile knitted fabric.
[0002]
[Prior art]
Needless to say, towels and handkerchiefs are used to wipe the human body. Of these, towels are generally used in pile knitted fabrics, and the touch is required as a particularly important function.
[0003]
On the other hand, liquid crystal displays (liquid crystal panels) are often used as display devices in electronic devices and electrical appliances with display devices such as personal computers, televisions, and digital cameras, but the display surfaces of liquid crystal displays are made of a thin resin film. Therefore, unlike a cathode ray tube, it may be damaged if wiped with a general towel or mop.
[0004]
For this reason, liquid crystal displays have been wiped with a mop or a soft paper such as tissue paper. In addition, there are storage medium discs such as CDs and MDs as articles for which scratches are strictly prohibited, and it has been necessary to carefully clean the discs with dust.
[0005]
Furthermore, there are optical devices such as cameras and lenses for spectacles that require careful wiping off dust and dirt. For removing dust from these lenses, wipes with pile layers or raised layers formed on both the front and back sides of the ground structure In addition, a wiping cloth plain-woven with multifilaments made of a bundle of yarns having a fineness of about 0.01 denier has been used.
[0006]
And when a pile layer is formed on both front and back surfaces of a towel or a lens wiping cloth, conventionally, a knitted fabric with the same height of the front and back pile layers is used. .
[0007]
[Problems to be solved by the invention]
By the way, the liquid crystal display is not composed of only the display surface, but includes a frame made of synthetic resin. Further, electronic devices such as personal computers are provided with other devices such as a main body and a keyboard in addition to the display, and it is necessary to wipe off dusts other than the display surface.
[0008]
In addition, in optical devices and glasses, it is necessary to wipe off dirt on non-lens parts such as bodies and frames. Furthermore, for example, when wiping the body of a person at a beauty salon or esthetic salon, for example, when wiping the face and wiping the arms and legs, the wiping part, purpose, use, etc. Depending on the difference, you may want to change the functions such as softness and touch.
[0009]
The desire to make the skin feel different depending on the site and purpose of wiping the human body can be considered for towels used for patients in hospitals and nursing towels. Of course, there are a case where a touch function is preferentially obtained and a case where a dirt scrubbing function is preferentially obtained for a wipe used by a person to wipe the body.
[0010]
As described above, the wiping cloth used for the article and the wiping cloth used for the human body are often required to have a difference in functions such as softness, touch or water absorption.
[0011]
However, the conventional pile knitted fabric made of wiping cloth for the front and back both sides had been in the same state, in answer to the user's requests, will be must be kept to prepare a plurality of types, with this order handling is troublesome There was a problem of poor usability.
[0012]
The present invention aims to improve such a current situation.
[0013]
[Means for Solving the Problems]
In the invention of claim 1 for achieving the above object, in the front surface and the back surface of the ground structure, the group of units pile forms a pile layer that is knitted in alignment number, each of the unit pie Le is In a knitted fabric that is held in a loop shape and the height of the pile layer on the front surface side and the pile layer on the back surface side is different, the pile layer on the front and back surfaces is composed of a bundle of a large number of yarns. The yarn is knitted with multifilaments, and the raw yarn is a synthetic monofilament having a fineness of 0.05 denier or less, and the raw monofilament monofilament is torn to form the raw yarn.
[0014]
In claim 1, the height dimension and the ratio of the height of the front and back piles are not limited. However, in order to efficiently take up the hocols by utilizing the three-dimensionality of the piles, a pile layer having a low height may be used. A height of at least about 1 mm is preferable (1.5 mm or more is particularly preferable).
[0015]
Further, the difference in height between the front and back pile layers is preferably at least 1.5 times or more (more preferably 2 times or more). When the height is different to this extent, the user can be surely recognized the difference in volume between the front and back pile layers, and the use (use location) of the front and back can be distinguished.
[0016]
A second aspect of the present invention, which was devised as suitable wiping cloth used to clean the equipment with LCD display, given the configuration of claim 1, the one of the pile layer of the front back both pile layer The height is set to about 4 mm, and the height of the other pile layer is set to about 2 mm.
[0017]
In the present invention, the fineness of the pile yarn is more preferably about 0.02 denier.
[0018]
[Operation and effect of the invention]
According to the present invention, by changing the height of the pile layer between the front surface and the back surface, it is possible to differentiate the functions such as softness and feel between the front surface and the back surface.
[0019]
For this reason, for example, a pile layer with a high height is used for a portion that needs to be wiped with a soft touch, and a pile layer with a low height is used for a portion that can be wiped with a certain amount of force. You can do two roles. For this reason, the usability of the wiping cloth can be significantly improved.
[0020]
By the way, there are wiping cloths such as velor fabrics that are made non-looped by cutting the tip of the pile, and those that raise the surface of the ground tissue. Since the tip is often a sharp edge, wiping a soft object may damage the other party, and may be inferior to the touch when used on a person.
[0021]
On the other hand, if each unit pile is left in a loop shape as in the present invention, it will not be damaged by wiping a soft object, and it is excellent in softness when used for humans. Further, since the pile layers on the front and back sides are knitted in advance to have different heights, there is no need for a process such as raising or cutting, which is excellent in terms of cost.
[0022]
Since the display surface of the liquid crystal display is easily scratched as described above, it is necessary to handle it softly even when wiping dust. The inventor of the present application repeated experiments on this point. When a high-pile pile layer is knitted to about 4 mm by using a synthetic fiber having a fineness of 0.05 denier or less as a raw yarn, it is excellent in softness and dust wiping property. It was suitable.
[0023]
Further, for example, for wiping hard made of a material portion such as a computer and keyboard, but it should be prioritized rub Installing function dirt than softness and, 2 mm height of lower height pile layer When the height was about high, it was suitable because it had an appropriate volume and was excellent in the function of removing dirt and dust.
[0024]
Also, if the height of the pile layer is too high, the pile will fall asleep due to use or the pile will fall asleep after washing, and the softness will be impaired, but the original yarn is about 0.05 denier or less in case of using the extra fine chemical fiber, when the high pile layer height set to about 4mm height of about (about 3.5～4.5Mm), the held state of projecting from the foundation structure lose softness and It was suitable.
[0025]
By the way, if the ratio of the height of the pile layers on the front and back sides is small, it is difficult for humans to visually recognize the difference in the height of the pile layers.For example, when using a wiping cloth for a personal computer, the liquid crystal display surface is displayed with a low pile layer. There is a risk that the liquid crystal screen may be damaged due to the dust adhering to the low pile layer because the main body is wiped.
[0026]
On the other hand, if the height of the pile layer on the front and back is set to about twice as high as in claim 2, the user can visually recognize the difference in the height of the pile layer on the front and back. Therefore, the user can use the pile layer on the front and back sides to use the high-pile pile layer exclusively for removing dust from the LCD screen and the low-pile pile layer to other parts. The use can be clearly distinguished, which is preferable.
[0027]
In addition, it cannot be overemphasized that the wipe of Claim 2 can be used not only for apparatus with a liquid crystal display but for other uses, such as being used for a human body.
[0028]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0029]
FIG. 1 is a perspective view of the wiping cloth in a state of being turned upside down, FIG. 2A is a perspective view schematically showing the front side of the wiping cloth, and FIG. 1B is a schematic showing the back side of the wiping cloth. FIG. 3 is a schematic cross-sectional view of a wipe.
[0030]
(1). Configuration The wiping cloth is knitted by a knitting machine having a two-row needle bed such as a double raschel knitting machine, and has a ground structure 1 and a surface pile layer 2 formed on the surface side of the ground structure 1 The back pile layer 3 is formed on the back side of the ground structure 1. The number of gauges is 28, for example.
[0031]
Both the front pile layer 2 and the back pile layer 3 are composed of a large number of unit piles 4 and 5, and these unit piles 4 and 5 are entangled with the ground structure 1 at appropriate intervals, and are vertically and horizontally at a constant pitch. They are lined up in an aligned state. Then, about 4mm height dimension H1 of Table pile layer 2 is set the height of the back pile layer 3 H2 to about 2 mm. Therefore, the ratio of the heights of the pile layers 2 and 3 is about 2: 1.
[0032]
The wiping cloth of this embodiment is a mode suitable for dust removal of a device with a liquid crystal display, and a 150 denier / 48-filament multifilament is used as the yarn of the ground structure 1 from the viewpoint of securing an appropriate waist and thickness. is doing.
[0033]
On the other hand, as shown in FIG. 4, the filament 6 constituting the front and back pile layers 2 and 3 uses a multifilament in which an extremely large number of raw yarns 7 are bundled, and is very loosely twisted. Since the pile yarn 6 has a very light twist, when it is knitted and piled, the unit piles 4 and 5 are twisted loosely as shown in FIG. 5 due to the restoring force resulting from the twist. It has become. For this reason, the unit piles 4 and 5 are in a state in which the raw yarns 7 can be obtained with a light force while maintaining their independence.
[0034]
4C is a cross-sectional view taken along the line C-C of FIG. 4A. As shown in FIG. 4C, the cross section of the raw yarn 7 constituting the pile yarn 6 is shown in FIG. ).
[0035]
The reason why the raw yarn 7 has such a cross-sectional shape is that, as shown in FIG. 4 (D), a monofilament monofilament 8 having a regular octagonal cross section that is torn into eight equal parts is used. It is. The monofilament 8 for raw yarn has a fineness of 0.13 denier. Therefore, the fineness of the raw yarn 7 is about 0.016.
[0036]
A suitable numerical value of the fineness of the entire pile yarn 6 varies depending on the number of gauges, but in the case of 28 gauges, it was suitable to be about 75 denier. It is preferable that the fineness is reduced when the number of gauges is increased, and the fineness is increased when the number of gauges is reduced so that the entire volume of the pile layers 2 and 3 is substantially constant.
[0037]
In general, the fineness of the pile yarn 6 is considered to be preferably about 50 to 100 denier. In addition, for example, a multifilament made of a bundle of raw yarns 7 is one unit (one filament), and an intermediate yarn of 75 denier and 36 filaments and an intermediate yarn of 150 denier and 48 filaments as a whole are 225 deniers / 84. It is also possible to form the pile yarn 6 with a plurality of intermediate yarns having different denier numbers and filament numbers, such as forming the filament pile yarn 6. Practically, a range of about 50 to 300 denier is assumed as a whole.
[0038]
Various materials can be used as the raw material for the base fabric and the raw material for the pile 7, but in the present embodiment, a material obtained by blending polyester and nylon is used. The blend ratio was preferably 70% polyester and 30% nylon.
[0039]
In the present embodiment, the wiping cloth is manufactured by cutting a large area of the original fabric in order to suppress the manufacturing cost. In order to prevent the peripheral edge from being unraveled, the peripheral edge portion of the wiping cloth is welded with a seal bar and overlock stitching is performed. The four peripheral portions of the wiping cloth are formed by integrally pressing the ground structure and the front and back pile layers. In FIGS. 1 and 2, the four peripheral portions are indicated as the ground structure 1 for convenience.
[0040]
(2). Summary As can be understood from the above description, the surface pile layer 2 of the wiping cloth is composed of very thin yarns 7 and is high in pile height, so it is soft and lightly touches the object. You can wipe off dust. For this reason, for example, it is most suitable for wiping dust on the display surface of a liquid crystal display or recording disks.
[0041]
On the other hand, since the back pile layer 3 is low in height and excellent in shape retention, a certain amount of force is applied as in the case of removing dust or dirt on the frame of a liquid crystal display, the body of a personal computer, or a CD case. Suitable for scraping off dirt and the like.
[0042]
By the way, even if the pile is knitted to a high height, if it falls down easily and falls asleep due to use or washing, the soft feeling is significantly attenuated. On the other hand, if a raw yarn having a large fineness is used, even if the shape of the pile can be maintained, the soft feeling is inferior, and the original softness cannot be exhibited.
[0043]
On the other hand, when a multifilament with a very light twist is used as the pile yarn 6 as in the present embodiment, each unit pile 4, 5 is composed of an extremely thin raw yarn 7. In other words, the unit piles 4 and 5 are made of very thin yarns (super extra fine fibers), so they have a moderate waist and are not easily deformed. There is an advantage that can be maintained over a long period of time.
[0044]
It is also possible to form the pile layers 2 and 3 uniformly densely over the entire surface of the ground structure 1, but an appropriate interval is provided between the adjacent unit piles 4 and 5 as in this embodiment. If left free, the unit piles 4 and 5 are allowed to bend appropriately, so that the softness (soft feeling) is excellent. As the ultrafine yarn, a 0.13 denier material yarn that has been split into 12 equal parts has been put into practical use. Such a raw yarn can also be used in the present invention.
[0045]
In the ground organization 1, for example, when the density of the mesh is small such that the number of meshes per inch is the same as the gauge number, even if the unit piles 4 and 5 are entangled for each mesh, they are adjacent to each other. A suitable space can be provided between the unit piles 4 and 5.
[0046]
When the number of meshes per unit length of the ground organization 1 is larger than the gauge number and the density of the mesh is high, the unit piles 4 and 5 are in a state of one jump or multiple jumps with respect to the mesh of the ground organization 1 The unit piles 4 and 5 can be set to an appropriate density. It is also possible to use raw yarns having the same fineness for the ground structure 1 and the pile layers 2 and 3.
[0047]
Further, for example, the characters “for display” are displayed on the pile layer 2 having a high height, and the characters “for main body” are displayed on the pile layer 3 having a low height. It is also possible to display the application location by appropriate means such as textile printing or printing.
[0048]
(3). Others The present invention can be embodied in various ways other than the above embodiment. For example, the material of the ground texture, the fineness, the cross-sectional shape of the yarn, the knitting structure (weave structure), the pile material, the fineness, the cross-sectional shape of the yarn, the pile height, the density of the pile, etc. The type, the number of gauges, etc. can be embodied in various ways depending on the application.
[0049]
For example, it is also possible such constitute a table behind the pile layer in the raw yarns of different fineness.
[0050]
Needless to say, the size and shape of the wiping cloth can be freely set as required. Further, the Wipe cloth is a concept including those with other functions such as heating as towel.
