Description

The present invention relates to a knitted cloth and a cleaning tool using the knitted cloth.

Conventionally, knitted fabrics have been used not only for clothing but also for various purposes such as bags and cleaning tools, and functions or designs are required for each application.
For example, Patent Document 1 below proposes a cleaning tool in which the sponge is stored in a bag-shaped knitted cloth (net) in order to improve the foaming of a sponge made of a resin foam such as urethane foam. Has been done.
In some cases, the cleaning tool is composed only of knitted cloth without storing the sponge.

In general, the knitted fabric is bulkier than the woven fabric, so that the content of air and liquid is high, and depending on the design, uneven portions formed by the knitting means can be added to the surface. The uneven portion can add design to the knitted fabric and contribute to further improvement of the content of air and liquid. Further, when the knitted fabric is used for a specific purpose, it is possible to exert a function according to the use in the uneven portion.

For example, in a cleaning tool made of a knitted cloth having the uneven portion on the surface, the uneven portion exerts a function of scraping dirt and increases the content of gas or liquid. Therefore, the cleaning tool configured by using the knitted cloth having the uneven portion on the surface has good foaming and high cleaning property. Of course, the uneven portion can give the cleaning tool a design.

Further, clothing or the like made of a knitted fabric having the above-mentioned uneven portion has excellent design and heat retention.

By the way, due to its structure, when the knitted fabric is pulled in the knitting direction, the entire knitted fabric is stretched by extending each stitch (loop) in the knitting direction, and when the pulling force is released, the elasticity of the knitted yarn is released. Therefore, it has elasticity to shrink to its original shape. While the above elasticity is an advantage of knitted fabric, it has the following problems.

That is, when the knitted fabric is greatly extended in the knitting direction, the overall thickness is reduced and the bulkiness is reduced. The uneven portion formed on the surface of the knitted fabric also expands and flattens in conjunction with the elongation of the knitted fabric itself. Therefore, the stretched knitted fabric may have a lower gas or liquid content than before the stretched fabric, resulting in impaired design.
As a result, various problems may occur in each application using the knitted fabric. For example, when the cleaning tool made of a knitted cloth having the uneven portion is stretched in the knitting direction, the knitted cloth itself and the uneven portion are flattened, so that there is a concern that the foaming property and the cleaning property may be deteriorated. In addition, when the knitted fabric having the uneven portion is partially or wholly arranged, when the garment is stretched in the knitting direction, there is a concern that the heat retention property and the design property may be deteriorated.

The present invention has been made in view of the above-mentioned problems. That is, the present invention has an uneven portion on the surface, which exerts various effects such as improvement of gas or liquid content, addition of dirt scraping function, or improvement of design, and knitted fabric. A knitted fabric in which the uneven portion is prevented from being completely flattened and the above effect can be maintained even when the knitted fabric is pulled in the knitting direction while maintaining its own appropriate elasticity, and the knitted fabric. The cleaning tool used is provided.

The knitted fabric of the present invention is a knitted fabric that alternately includes a convex portion extending in the lateral direction, which is a direction intersecting the knitting direction, and a concave portion extending in the lateral direction on one surface side. The ridge portion is formed by forming a first loop row having two or more first loops composed of the first yarn in the knitting direction, which are continuous in the lateral direction. The concave portion is formed by forming a second loop row having a second loop composed of the second thread continuous in the lateral direction, and the elasticity of the first thread is the first. It is smaller than the elasticity of the two yarns, and is less than the number of first loops forming the first loop row between one first loop row adjacent to each other in the lateral direction and the other first loop row. It is characterized by having a third loop sequence consisting of a number of third loops.

The cleaning tool of the present invention is characterized by using the knitted cloth of the present invention.

The knitted fabric of the present invention having the above structure has a convex portion on one side surface, has a high content of gas or liquid, exhibits various effects such as showing excellent design, and exhibits appropriate elasticity. At the same time, even when the ridges are pulled in the knitting direction, the flattening of the ridges is prevented.
The cleaning tool of the present invention using the above-mentioned knitted cloth has the above-mentioned ridges, so that it has good foaming property and a function of scraping dirt, and even when it is pulled in the knitting direction, the ridges are formed. Since flattening is prevented, various effects due to the provision of the convex portion are maintained.

<First Embodiment>
Hereinafter, the first embodiment of the knitted fabric of the present invention will be described with reference to FIGS. 1 and 2. Further, with respect to the description of the comparative example of the present invention, FIG. 5 will be used as appropriate.
FIG. 1 is a top view of the knitted fabric 100 according to the first embodiment of the present invention. 2A and 2B are schematic side views when the side surface of the knitted fabric 100 according to the first embodiment is observed from the lateral direction B, and FIG. 2A shows a state in which no force is applied to the knitted fabric 100. FIG. 2B shows a state in which a tensile force is applied to the knitted fabric 100 in the knitting direction A. 5A and 5B are schematic side views when the side surface of the knitted fabric 400 to be compared of the present invention is observed from the lateral direction, and FIG. 5A shows a state in which no force is applied to the knitted fabric 400. FIG. 5B shows a state in which a tensile force is applied to the knitted fabric 400 in the knitting direction A.

First, the outline of the knitted fabric 100 of the present embodiment will be described.
As shown in FIG. 1, the knitted fabric 100 has a convex portion 10 extending in the lateral direction B, which is a direction intersecting the knitting direction A, and a concave portion 20 extending in the lateral direction B on one surface side. , Are provided alternately.
The ridge portion 10 is formed by having a first loop row 16 having two or more first loops 14 composed of the first yarn 12 in the knitting direction A continuous in the lateral direction B. On the other hand, the concave portion 20 is formed by having a second loop row 26 having a second loop 24 composed of the second thread 22 continuous in the lateral direction B. The state of unevenness on one side of the knitted fabric 100 due to the provision of the convex portion 10 and the concave portion 20 is shown in FIG. 2A, which is a schematic side view of the side surface of the knitted fabric 100 observed from the lateral direction B. Easy to understand.

In the knitted fabric 100, the first yarn 12 is selected to have elasticity smaller than that of the second yarn 22. By making the elasticity of the first thread 12 and the second thread 22 different in this way, the first loop row 16 composed of the first thread 12 having a relatively small elasticity has a relatively large elasticity. The second loop row 26 composed of the second yarn 22 rises so as to protrude in the plane direction of the knitted fabric 100 (see FIG. 2A). The ridge portion 10 is formed by the raised first loop row 16 being continuous in the lateral direction B. Further, a concave portion 20 which is a relatively concave portion is formed between the convex portion 10 and the convex portion 10. By using the first yarn 12 and the second yarn 22 having different elasticity as described above, when the knitted fabric 100 is manufactured, it is not necessary to change the knitting method in order to form an uneven portion on one side surface, and it is simple and easy. Clearly, the ridges 10 and the ridges 20 can be formed.

The elasticity of the yarns such as the first yarn 12 and the second yarn 22 constituting the knitted fabric 100 is confirmed as follows. That is, using two types of yarn, flat knitting is performed on a flat knitting machine at a speed of 1.0 m / min under the condition that one type of the above two types of yarn is repeatedly knitted every four courses to form a tubular knitted fabric. To make. The obtained tubular knitted fabric is observed with the naked eye, and on the inner surface of the tubular knitted fabric, the yarn constituting the ridge portion is set as the first yarn, and the yarn is relatively concave between the adjacent ridge portions. The thread constituting the concave portion is the second thread.
The flat knitting machine is a knitting machine that knits a knitted fabric using a flat needle bed, and examples thereof include a WHOLEGARMENT flat knitting machine SWGO61N2 manufactured by Shima Seiki Seisakusho Co., Ltd. When confirming the elasticity of the first yarn and the second yarn by using such a WHOLEGARMENT flat knitting machine, for example, it is preferable to set the degree to about 40 to produce a tubular knitted fabric. The above course refers to a stitch extending in a direction intersecting the knitting direction (the yarn feeding direction, which is consistent with the above-mentioned lateral direction).

The knitted fabric 100 has a third loop row 36 between one adjacent first loop row 16 and the other first loop row 16 in the lateral direction B. The third loop row 36 is configured to have a number of third loops 34 that is less than the number of first loops 14 that make up the first loop row 16. By providing the third loop row 36, the knitted fabric 100 is prevented from being completely flattened even when the knitted fabric 100 is pulled in the knitting direction A, and the ridge portion 10 is provided. The effect is maintained well. The action and effect of providing the third loop row 36 will be described below.

First, as a comparison target, the knitted fabric 400 configured in the same manner as the knitted fabric 100 except that it does not have the third loop row 36 will be described. A schematic side view of the knitted fabric 400 is shown in FIG. 5A. The knitted fabric 400 is formed of a first loop row 16 having a plurality of first loops 14 formed of first yarns 12 having relatively low elasticity, and a second yarn 22 formed of second yarns 22 having relatively large elasticity. A second loop row 26 having a plurality of two loops 24 is alternately provided in the knitting direction A. The convex strip portion 10 is formed by the continuous first loop row 16 from the front side to the back side of the paper surface of FIG. 5A, and the concave strip portion 20 is formed by the continuous second loop row 26 in the same direction. .. When the knitted fabric 400 is pulled in the knitting direction A (that is, in the left-right direction on the paper surface), the first loop 14 and the second loop 24 extend in the knitting direction A as shown in FIG. 5B, and the convex shape shown in FIG. 5A. The strip 10 and the recess 20 are flattened. In this state, the effect of providing the ridge portion 10 on the knitted fabric 400 is lost.

On the other hand, as shown in FIG. 1, the knitted fabric 100 according to the present embodiment has a first loop row 16 between one adjacent first loop row 16 and another first loop row 16 in the lateral direction B. A third loop row 36 having a smaller number of third loops 34 (specifically one in this embodiment) than the number of first loops 14 (specifically four in this embodiment). have. Therefore, as shown in FIG. 2A, in the side view, the third loop row 36 composed of the third loop 34 is observed in the back direction of the first loop 16. Similar to FIG. 5B described above, when the knitted fabric 100 is pulled in the knitting direction A (that is, the left-right direction of the paper surface), the first loop 14, the second loop 24, and the third loop 34 are pulled respectively. Extend in the direction. However, since the third loop row 36 has a smaller number of loops than the first loop row 16, the third loop row 36 reaches the extension limit prior to the first loop row 16, and the knitted fabric 100 further extends in the pulling direction. Regulate that. That is, in the knitting direction A, the fully extended third loop row 36 becomes a regulating portion that regulates that the first loop row 16 is fully extended and the ridge portion 10 is flattened by this. Therefore, in the knitted fabric 100, even when the knitted fabric 100 is strongly pulled in the knitting direction A, the ridge portion 10 is maintained at a certain height, and the effect of providing the ridge portion 10 is completely lost. It is maintained well without any problems.

According to the knitted fabric 100 having the above structure, by having the ridge portion 10, a space is secured in the ridge portion 10, and a gas or a liquid can be contained in the space. Therefore, the knitted fabric 100 exhibits functions such as improved foaming when used as a cleaning tool and improved heat retention when used for clothing. Further, when the knitted cloth 100 is used as a cleaning tool, the ridge portion 10 functions as a dirt scraping portion and contributes to improvement of cleaning property. Further, the knitted fabric 100 is excellent in designability by providing the convex portion 10. Moreover, as described above, since the knitted fabric 100 includes the third loop row 36, the ridge portion 10 is maintained without being completely flattened even when pulled in the knitting direction A. Therefore, the above-mentioned effect due to the provision of the convex portion 10 is not lost.

Further, even when the knitted fabric 100 repeats stretching and contracting in the knitting direction A, the third loop row 36 is fully stretched ahead of the first loop row 16, so that the first loop row 16 is pulled to the limit. There is nothing to be done. Therefore, at least the first yarn 12 used in the first loop row 16 can maintain a good elastic force for a long period of time as compared with the yarn (third yarn) constituting the third loop row 36. As a result, the shape of the ridge portion 10 can be maintained satisfactorily for a long period of time.

Next, the knitted fabric 100 of the present embodiment will be described in detail.
As shown in FIG. 1, the knitted fabric 100 in the present embodiment alternately includes a convex portion 10 extending in the lateral direction B and a concave portion 20 extending in the same direction on one surface side. .. In the present embodiment, the convex portion 10 and the concave portion 20 are substantially parallel to each other. Here, when the convex portion 10 and the concave portion 20 extend in the lateral direction B, the convex portion and the concave portion between the convex portion and the convex portion are continuous so as to extend in the lateral direction B. It means that it exists.

The ridge portion 10 is formed by the first loop row 16 being continuous in the lateral direction B. The plurality of first loops 14 constituting the first loop row 16 are each composed of the first thread 12. On the other hand, the concave portion 20 is formed by the second loop row 26 being continuous in the lateral direction B. One or more second loops 24 constituting the second loop row 26 are composed of the second yarn 22. At the boundary between the convex portion 10 and the concave portion 20, the first loop 14 and the second loop 24 are linked. Similar to a general knit, the knit 100 is connected in the lateral direction B between the adjacent first loops 14 and 14 by the first thread 12 constituting them. The connecting portion to be sewn is referred to as a connecting portion 18. Similarly, in the lateral direction B, the adjacent second loops 24 and 24 are connected by the second thread 22 constituting them. The connecting portion to be sewn is referred to as a connecting portion 28.

The first thread 12 may be a thread having a relatively smaller elasticity than the second thread 22. Therefore, the thickness and material of the first thread 12 are not particularly limited. Similarly, the thickness and material of the second thread 22 are not particularly limited. When the first yarn 12 and the second yarn 22 are made of the same material, the elasticity can be adjusted by making the diameter of the yarn relatively small. In the present embodiment, the first thread 12 and the second thread 22 are made of the same material, and by making the diameter of the first thread 12 larger than that of the second thread 22, the first thread 12 and the second thread 22 are first compared to the second thread 22. The elasticity of the thread 12 is adjusted to be relatively small.

The convex portion 10 may contain a thread having elasticity different from that of the first thread 12 as long as the convex shape is not obstructed, and the concave portion 20 is long as the concave shape is not obstructed. A thread having elasticity different from that of the second thread 22 may be included.

The yarns used as the first yarn 12 and the second yarn 22 are appropriately selected from the yarns that can form the knitted fabric 100. Examples of the above-mentioned yarn include resin yarns made of cotton yarn, polyester, nylon, polyolefin and the like, and metal yarns made of copper, iron, stainless steel, aluminum and the like. Further, the yarn may be either a monofilament yarn which is a single fiber or a multifilament yarn produced by twisting a large number of fibers. The first thread 12 and the second thread 22 may be selected from threads made of the same type of material or may be selected from threads made of different materials, as long as the magnitude of the bending elasticity is indicated.
From the viewpoint of selecting a yarn having remarkably low elasticity and reliably forming the ridge portion 10, the aspect ratio of the first yarn 12 in the cross section is 1: 1.5 or more and 1: 100 or less. It is preferable to select a slit thread. The slit thread is generally a resin thread having a flat cross section and has a high hardness. Therefore, the knitted cloth 100 provided with the ridge portion 10 formed by using the slit yarn can be used for the cleaning tool, and the dirt scraping function of the cleaning tool can be further enhanced.

The knitted fabric 100 according to the present embodiment is configured such that the number of the first loops 14 in the first loop row 16 is larger than the number of the second loops 24 in the second loop row 26. Specifically, in the present embodiment, the number of the first loops 14 in one first loop row 16 is four, and the number of second loops 24 in one second loop row 26 is two. is there. By increasing the number of the first loops 14 constituting the ridges 10 to be larger than the number of the second loops 24 forming the ridges 20, the ridges 10 are clearly formed and the ridges 10 are formed. It is possible to remarkably exert the effect of providing the ridge portion 10, such as increasing the volume of the space secured by the above.
However, to the extent that the gist of the present invention is not deviated, the present invention has an aspect in which the number of first loops 14 in the first loop row 16 is the same as the number of second loops 24 in the second loop row 26, and the first aspect. Includes aspects in which the two loops 24 are more common.

Next, the third loop sequence 36 will be described. As described above, the third loop row 36 is composed of the third loop 34 formed by using the third yarn. The number of third loops 34 in one third loop row 36 is less than the number of first loops 14 in one first loop row 16. The third loop 34 existing between the first loop rows 16 and 16 is a loop having a relatively large diameter as compared with the first loop 14 in the knitting direction A. The number of first loops 14 in one first loop row 16 is preferably twice or more, and more preferably three times or more, as compared with the number of third loops 34 in one third loop row 36. It is preferable, and it is more preferable that it is 4 times or more. In this embodiment, a four-fold example is shown. As described above, the larger the number of the first loop 14 than the number of the third loop 34, the more the convex portion 10 when the knitted fabric 100 is pulled in the knitting direction A and reaches the extension limit of the third loop row 36. The shape of the is well maintained. However, if the number of third loops 34 in one third loop row 36 is too small compared to the number of first loops 14 in one first loop row 16, the dimension of the third loop 34 in the knitting direction A becomes large. It becomes too large, and a finger or an arbitrary article is likely to be caught in the third loop 34, which may cause the stitches to hang. From this point of view, in one third loop row 36 and one first loop row 16, the number of first loops 14 is preferably 10 or less with respect to one third loop 34, and eight. It is more preferably less than or equal to, and even more preferably 5 or less.

The number of the third loops 34 constituting one third loop row 36 is not particularly limited, but is specifically one in the present embodiment. As shown in FIG. 1 or 2, the knitted fabric 100 in the present embodiment is composed of a first loop row 16 composed of four first loops 14 and one third loop 34 in a top view. The third loop row 36 and the third loop row 36 are alternately continuous in the lateral direction B. By setting the number of the third loops 34 constituting the third loop row 36 to one in this way, the structure of the knitted fabric 100 can be made simple and easy to manufacture.

In the knitted fabric 100 according to the present embodiment, the third yarn forming the third loop 34 is common to the second yarn 22 forming the second loop 24. More specifically, in the present embodiment, a large-diameter loop is formed by the second thread 22 forming the second loop 24 between the second loop rows 26, 26 forming the concave portion 20. Is the third loop 34. By using both the second yarn 22 and the third yarn in this way, the types of yarns used in manufacturing the knitted fabric 100 can be reduced, and the manufacturing process can be simplified.

In this embodiment, the second loop row 26 is composed of two second loops 24. That is, two second threads 22 are used in the second loop row 26. One of the two second threads 22 is also used as the third thread for forming the third loop 34. The remaining second yarn 22 that is not also used for the configuration of the third loop 34 constitutes a linking loop 35 that links the third loop 34 and the third loop 34 in the knitting direction A. In this embodiment, the linkage loop 35 has substantially the same dimensions as the second loop 24. It is not essential to provide the linking loop 35 in the present embodiment, and as a modification omitted from the illustration, the linking loop 35 may be omitted and the third loops 34 may be directly connected to each other in the knitting direction A.

The relative magnitude of elasticity of the third yarn with respect to the first yarn 12 and the second yarn 22 is not specified. The third yarn may be substantially the same as the first yarn 12 or the second yarn 22, or may be a yarn exhibiting elasticity different from that of the first yarn 12 and the second yarn 22. The third yarn may be appropriately selected from the same yarns as the first yarn 12 and the second yarn 22 described above.

When the protrusion direction of the ridge portion 10 is the upward direction and the vertical direction is the downward direction in the knitted fabric 100, the third loop row 36 in the present embodiment is located lower than the first loop row 16. ing. That is, the third thread (the thread that is also used as the second thread 22) constituting the third loop row 36 passes under the first thread 12. In the top view of FIG. 1, the third loop row 36 is visually recognized downward between the first loop rows 16 and 16. However, by appropriately adjusting the length of the connecting portion 18 connecting the first loop rows 16 and 16, the actual knitted fabric 100 is substantially third from the one side surface on which the ridge portion 10 is visually recognized. The loop row 36 can be organized so that it is not visible. As a result, the knitted fabric 100 is prevented from deteriorating the design on one side surface by visually recognizing the third loop row 36. When the surface provided with the ridge portion 10 is the front side and the opposite side surface is the back side, the knitted fabric 100 has a finger or a finger on the front side with respect to the third loop 34 having a diameter larger than that of the first loop 14 and the second loop 24. The problem that any article is caught and the stitches are hung is prevented.

The means for producing the knitted fabric 100 in the present embodiment is not particularly limited, and includes either mechanical knitting or hand-knitting means. For example, the knitting fabric 100 of the present embodiment is knitted by a flat knitting machine. The knitting method of the knitted fabric 100 of the present embodiment is not particularly limited, and any generally known knitting method such as flat knitting, rubber knitting, pearl knitting, or knitting may be adopted. The knitted fabric 100 can be provided with the ridge portion 10 and the ridge portion 20 by making the elasticity of the first yarn 12 and the second yarn 22 different regardless of the type of knitting method. In the present embodiment, each loop is composed of one knitting yarn, but as a modification omitted from the illustration, any one of the first loop 14, the second loop 24, and the third loop 34 , Or a combination, or all of them may be composed of two or more (that is, a plurality of yarns) knitting yarns.

<Second embodiment>
Next, the knitted fabric 200 according to the second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a top view of the knitted fabric 200. The knitted fabric 200 is different from the above-mentioned knitted fabric 100 in that the knitting yarn forming the third loop 34 is the third yarn 32, which is different from the second yarn 22.

The configuration of the knitted fabric 200 will be described in detail. As shown in FIG. 3, the knitted fabric 200 alternately includes a convex portion 10 extending in the lateral direction B and a concave portion 20 extending in the lateral direction B on one surface side. In the present embodiment, the ridge portion 10 is configured such that the first loop row 16 having three first loops 14 composed of the first yarn 12 in the knitting direction A is continuous in the lateral direction B. ing. On the other hand, the concave portion 20 is formed by having a second loop row 26 having two second loops 24 composed of the second yarn 22 continuous in the lateral direction B. The elasticity of the first thread 12 is smaller than the elasticity of the second thread 22 as in the first embodiment.

The knitted fabric 200 has a number smaller than the number of the first loops 14 forming the first loop row 16 between one adjacent first loop row 16 and the other first loop row 16 in the lateral direction B. It has a third loop row 36 having three loops 34.

In the knitted fabric 200 according to the present embodiment, the yarn (third yarn 32) forming the third loop 34 is not common with the second yarn 22 forming the second loop 24. Further, the first loop 14 formed by the first thread 12 and the second loop 24 formed by the second thread 22 are linked at an arbitrary position (for example, the boundary between the convex portion 10 and the concave portion 20). However, these loops and the third loop 34 formed by the third thread 32 are not linked to each other. In other words, the third loop row 36 is independent of the first loop row 16 and the second loop row 26.

However, in the knitted fabric 200, when the protruding direction of the ridge portion 10 is the upward direction and the opposite direction is the downward direction, the third thread 32 is up and down with respect to the first thread 12 and the second thread 22. Crossing at. Therefore, the third loop row 36 is not separated from the first loop row 16 and the second loop row 26. Specifically, in the present embodiment, the third thread 32 is arranged below the first thread 12 between the adjacent first loop rows 16 and 16, while the adjacent second loop row 26 , 26 is arranged on the upper side of the second thread 22.

In the present embodiment, the third loop row 36 is composed of one third loop 34. The third loop 34 in the present embodiment corresponds to the three first loops 14 forming the first loop row 16 and the two second loops 24 forming the second loop row 26 in the knitting direction A. The diameter is large enough to do.

As described above, the third loop row 36 in the knitted fabric 200 is independent of the first loop row 16 and the second loop row 26. When the knitted fabric 200 is pulled in the knitting direction A, it is difficult for the first yarn 12 and the second yarn 22 to follow the extension of the large-diameter third loop 34. Therefore, when the extension of the knitted fabric 200 with respect to the knitting direction A is restricted by the third loop 34 reaching the extension limit, the concave portion 20 is suspended from the third thread 32 and a part of the shape is deformed. , There is no possibility that the convex portion 10 will be deformed due to the deformation of the concave portion 20. Therefore, when the knitted cloth 200 is pulled in the knitting direction A, the ridges 10 are not completely flattened like the knitted cloth 100, and the shape of the remaining ridges 10 is well maintained.

<Third Embodiment>
Next, the third embodiment of the present invention will be described with reference to FIG. FIG. 4A is a schematic perspective view of the cleaning tool 300 according to the third embodiment of the present invention, and FIG. 4B is a schematic cross-sectional view of the cleaning tool 300 showing the I-I cross section in FIG. 4A. In FIG. 4B, the first loop, the second loop, and the third loop are not shown individually, and the first loop row 16, the second loop row 26, and the third loop row 36 are linearly shown. Shown.

The cleaning tool 300 according to the present embodiment is configured by using the knitted cloth of the present invention. In the present embodiment, the cleaning tool 300 configured by using the knitted cloth 100 will be specifically described. By including the knitted cloth 100, the cleaning tool 300 exhibits a desirable function due to the characteristic structure of the knitted cloth 100. Specifically, the cleaning tool 300 can sufficiently contain gas and liquid (including detergent) by having the convex portion 10 in the knitted cloth 100, and exhibits good foaming property. Further, since the ridge portion 10 also exhibits a dirt scraping property, the cleaning tool 300 is excellent in cleaning property. Moreover, as described above, even if the knitted fabric 100 is pulled in the knitting direction A, the convex portion 10 is not flattened and the convex shape is maintained, so that the foaming property and the detergency are maintained well. Will be done.

The cleaning tool of the present invention may be composed of one knitted cloth 100, but in the present embodiment, the two knitted cloths 100 are opposed to each other to form a tubular shape or a bag shape (hereinafter referred to as a tubular shape or the like). The aspect of the constructed cleaning tool 300 is shown. It is preferable that the first knitted cloth 100 and the second knitted cloth 100 are arranged so as to face each other so that the convex portion 10 is arranged on the exposed surface side of the cleaning tool 300 such as a tubular shape. As a result, the cleaning tool 300 exhibits a function of scraping dirt by the ridge portion 10 on both sides and exhibits high cleaning performance.

Both the first knitted fabric 100 and the second knitted fabric 100 are formed so that the third loop row 36 is located below the first loop row 16. That is, by arranging the ridges 10 (first loop row 16) on the exposed surface side of the two knitted fabrics 100 arranged so as to face each other, the third loop row 36 is placed on the facing surface side of the cleaning tool 300. To position. As a result, in the cleaning tool 300, the third loop row 36 is less likely to be visually recognized by the user, and the user's finger or the object to be cleaned is less likely to get caught in the third loop row 36.

The method for manufacturing the cleaning tool 300 is not particularly limited. For example, by continuously knitting the first knitting cloth 100 and the second knitting cloth 100 with a knitting machine such as a flat knitting machine, a tubular cleaning tool 300 can be manufactured. Further, as a different manufacturing method, two individually knitted fabrics 100 are opposed to each other so that the ridges 10 are on the exposed surface side and joined to each other to manufacture a cleaning tool 300 having a tubular shape or the like. May be good. The joining means that the two knitted fabrics 100 are joined together so as not to be separated from each other by the washing operation, and may be any means such as sewing, knitting, or bonding.

The cleaning tool 300 shown is configured in a bag shape. Specifically, the first knitted fabric 100 and the second knitted fabric 100 form a loop at the lateral end 112 by being joined or continuously knitted. Further, in the first knitted fabric 100 and the second knitted fabric 100, one of the knitting direction end portions 114 is closed and the other is opened to provide an opening 110. The cleaning tool 300 configured in a bag shape in this way can insert the user's finger into the inside through the opening 110, and can satisfactorily clean the details of the portion to be cleaned, the curved surface, and the like. The present embodiment includes a mode in which openings 110 are provided at both ends of the knitting direction end 114 to form a tubular shape, and a mode in which both the knitting direction end 114 are closed without the opening 110.

As a modification (not shown), in the cleaning tool 300, a porous body may be arranged between the first knitted cloth 100 and the second knitted cloth 100. That is, the porous body may be included in the bag-shaped cleaning tool 300. By providing a porous body inside, the foaming property or cushioning property of the cleaning tool 300 can be enhanced.

Here, the porous body is a solid having a plurality of pores capable of containing detergent and water and having appropriate elasticity, and is, for example, a resin foam (so-called sponge) such as urethane foam, a non-woven fabric, or the like. Alternatively, a fibrous body of a plant such as loofah sponge can be mentioned.

Although the embodiment of the knitted cloth and the cleaning tool using the knitted cloth have been described above, the knitted cloth of the present invention is widely used not only for the cleaning tool but also for various purposes. For example, part or all of the garment can be made of the knitted fabric of the present invention. In the present invention, clothing includes clothing, hats, gloves, footwear, and other body-worn attachments.
For example, in a garment having a first region and a second region that is required to expand and contract more repeatedly than the first region, it is preferable that the second region is composed of the knitted fabric of the present invention. It is an aspect. At this time, the knitted fabric used in the second region may be arranged so that the direction in which expansion and contraction is expected in the second region and the knitting direction of the knitted fabric are substantially the same direction. Further, in order to exhibit the design, it is preferable that the knitted fabric is arranged on the surface side of the garment so that the ridges can be visually recognized.
As described above, the knitted fabric of the present invention has a ridge portion on one side, so that it has a high design property, and since the ridge portion contains a large amount of gas, it is also excellent in heat retention. Further, the knitted fabric of the present invention has an appropriate elasticity, and when pulled in the knitting direction, the third loop row reaches the extension limit prior to the first loop row forming the ridge portion. .. Therefore, the extension of the first loop row is restricted and does not extend completely. Therefore, even when the second region is pulled in the knitting direction, the design and heat retention due to the ridges are well maintained in the second region.

When the garment is worn on the upper body such as a sweater or knit, the second area includes any or all of the collar, cuffs, or elbows. When the clothing is trousers, the second area includes knees and the like. In addition, it is preferable that the knitted fabric of the present invention is applied with the opening of the hat, footwear, or gloves through which the body enters and exits as the second region.

In general, the collar and cuffs of a sweater have a problem that the knitting yarns constituting the sweater lose their elastic force due to repeated stretching and are stretched completely. On the other hand, in the knitted fabric of the present invention, the protrusions are prevented from being fully stretched due to the presence of the third loop row. Therefore, in the garment of the present invention, the elasticity of at least the first yarn constituting the ridge portion is maintained for a long period of time in the second region, so that the above problem is unlikely to occur.
