PROBLEM TO BE SOLVED: To provide a leg wiping drying mat keeping excellent dry feeling and having excellent textile for a long period of time even though the large number of people use the same.SOLUTION: The leg wiping drying mat has an upper layer mat (a surface layer mat) constituted by weaving constituting yarns of antibacterial synthetic fiber with high water repellency into a predetermined shape and an under mat (an under layer mat) comprising a laminated structure of three kinds of polyurethane porous materials with different densities forming the first layer mat, the second layer mat, and the third layer mat from above.

Description

  The present invention has a non-slip effect as a good touch of the feet and a safety measure while ensuring water absorption, water retention and drying properties when used as a facility around a watering facility such as a dressing room, washstand, kitchen, etc. It relates to a rug that can be secured.

Traditionally, mats made of jute fibers and pile-woven (towel type) sheet-like mats made by bundling hygroscopic cotton and cellulosic fibers have been used as drying mats for feet. .

However, these foot-wiping dry mats become damp as a whole as they continue to be used, and moisture oozes out to the upper surface during the next person's use, giving the user an uncomfortable sticky feeling. Frequent replacement work was required.

Furthermore, in order to ensure water retention, those having a dense woven structure also have a problem in that it is difficult to dry the foot-drying mat when wet.

For this reason, recently, various researches have been conducted on foot-drying mats that can solve such problems and can keep the user uncomfortable and sticky for a long period of time even if they are used continuously. Has been. (For example, Patent Documents 1 to 3)

JP 2002-209709 A JP 2003-220659 A JP 2006-34797 A

The foot wipe drying mat described in Patent Document 1 includes a three-dimensional mesh sheet, a water permeable sheet provided on the upper surface side of the three-dimensional mesh sheet, and a water absorbing member interposed between the water permeable sheet and the three-dimensional mesh sheet. , Which is an integral laminated structure. Further, the foot wipe drying mat described in Patent Document 2 absorbs moisture with a water-permeable sheet of liner material (Technofine (registered trademark) fiber / component: made of 85% polyester and 15% polyurethane), and is a urethane foam as an inner material. A laminated sheet in which moisture is released to the outside by a passage (a continuous bubble in which bubbles are connected to each other) that are connected to a large number of continuous bubbles, and the inner material is sandwiched between upper and lower liner materials Therefore, one sheet or three or more sheets can be freely stacked according to the amount of moisture to be absorbed. Furthermore, the foot wipe drying mat described in Patent Document 3 uses a humidity control material containing diatomaceous earth having water absorption, water retention, and drying functions to absorb moisture with a porous ceramic tile. Release. Diatomaceous earth uses Wakkanai diatomaceous earth with very small pores, and has breathability (humidity control, moisture absorption and desorption) that releases moisture once absorbed, so it can be sun-dried in good weather or wind It is described that it can be used semipermanently by easily releasing internal moisture such as by hitting, and that it can maintain a sanitary condition without fear of generation of molds and bacteria.

Since the foot wipe drying mat described in Patent Document 1 maintains air permeability due to the gaps in the sheet having a three-dimensional mesh structure, the foot wipe drying mat exhibits an excellent quick drying property. Although a comfortable feeling of use can always be obtained, the limit of the amount of water retention is not clear, and the countermeasures for capacity over are unclear. In other words, even if it is possible to support the use of about 5 people or less at the level of general households, there is a possibility that the amount of absorption and water retention will be exceeded for the use of a large number of people for business purposes such as public baths. It has excellent moisture absorption and water retention for a long time beyond the limit, maintains a dry feeling, does not maintain a pleasant texture, and is still perfect as a foot wipe drying mat used by many people I can't say that.

The foot-wiping dry mat described in Patent Document 2 has a thickness of about 1 cm for a laminated sheet and a width of about 50 to 60 cm (normally the depth dimension is also equal to the width of the left and right). That's it. It is described that when 3 cc or more of water is dropped on the inner material, the capacity is exceeded in about 10 minutes, and water droplets appear on the surface (back surface) opposite to the surface on which the water droplets have been dropped (see Patent Document 2, column 0024, 0025). Column and FIG. 7). If the feet are wiped on a dry mat without wiping at the end of the bath, one person / about 50cc of water is absorbed and retained. Even when wiped out, water is absorbed and retained as 1 person / about 20 cc of water. In Patent Document 2, although the amount of water absorbed and retained by the total of the inner material and the liner material is not described, the required number of sheets when calculated using only the inner material is about 6.7 sheets (one sheet). The thickness is about 1 cm) and the total height (thickness) is about 7 cm. Moreover, since it is in this state by one person, when it is used by five persons, the height is 35 cm, which exceeds the height of a normal foot-wiping dry mat, and is not practical such as being one step or more on the stairs. It is done. In other words, it is not yet perfect as a foot-drying mat used by many people.

Similarly to Patent Document 1, the foot-wiping dry mat described in Patent Document 3 does not have a definite limit of water retention. If it is assumed that it will be used for business use, water absorption / retention will not be able to catch up with the number of users, and there is a possibility that the amount of absorption / retention will be exceeded. In addition, it is said that there is no generation of fungi such as mold, but in the case of over-quantification, there is a possibility that germs contained in moisture that cannot be absorbed may float on the mat, preventing the growth of mold and germs It doesn't seem to be a problem. Therefore, if the number of users and the drying speed are within the assumption of the foot-wiping dry mat described in Patent Document 3, even when used for a long time, a dry surface state can be maintained and a comfortable feeling can always be obtained. Although it seems that the function which can maintain a good hygiene state can be demonstrated to the maximum, it cannot be denied that it is difficult when the capacity is over. In other words, it is not yet perfect as a foot-drying mat used by many people.

By the way, more than 70% of foot-wiping dry mats currently used for business use are towel type (material: cotton). However, from the hot spring inns used by tens to hundreds of people, public baths such as day-trip hot springs, swimming pools, etc. It becomes a state of getting wet, and also causes discomfort for users. For this reason, the present situation is that the facility side frequently changes mats as a means of eliminating discomfort. As a result, the linen cost is increased, which is a big problem in the operation of the hot bath facility.

The point of this problem is, cost savings "drying of the superiority or inferiority of the mat in use" in the facility business hours with the decrease of the number of times of exchange, such as reduce the emissions of CO ₂ from the fact that the number of washing is reduced, the Earth from the cost surface “Products” with improved “dryness of mats in use”, such as improvements to the environment, are being sought by both users and hot bath facility operators.

  The present invention has been made in view of the above points, and its purpose is to solve the above-described conventional problems, and to maintain an excellent dry feeling over a long period of time even when a large number of people use it. It is another object of the present invention to provide a foot-drying mat having a texture.

The invention of claim 1 that achieves the above-mentioned object is as follows.
An upper mat (surface mat) that is woven into a predetermined shape using synthetic yarns with antibacterial processing and high water repellency;
An underlay mat (lower layer mat) comprising a laminated structure of three types of polyurethane porous bodies having different densities forming a first layer mat, a second layer mat, and a third layer mat from above.
It is a foot-drying mat characterized by comprising.

In the invention of claim 2, the upper mat (surface mat) uses acrylic fiber as a synthetic fiber forming the constituent yarn, and is any one of dobby weave, waffle weave, or pile weave. 2. The foot-wiping dry mat according to claim 1, comprising a woven fabric.

  According to a third aspect of the present invention, the underlay mat (lower mat) uses a polyurethane porous body, the first-layer mat having an air layer, the second-layer mat forming a moisture blocking layer, and moisture absorption / retention water retention. It consists of said 3rd layer mat which makes a layer, The foot-wiping dry mat of Claim 1 characterized by the above-mentioned.

According to a fourth aspect of the present invention, the first-layer mat is a polyurethane porous body having a concavo-convex portion formed on the surface thereof and a low foam density (35 to 40), and the second-layer mat is formed of a foam. A polyurethane porous body having a slightly high density (50 to 60), the third layer mat having a skin (thin film) on the lower surface, and a slightly hard polyurethane porous body having a foam density (35 to 45) It is a mass, It is a foot-wiping dry mat in any one of Claims 1-3 characterized by the above-mentioned.
Since the first-layer mat is a polyurethane porous body having a low foam density (35 to 40), it has excellent absorbability and has an uneven portion on the surface in order to secure a large air space. . Since the second layer mat is a polyurethane porous body having a slightly higher foam density (50 to 60), it has a moisture barrier property as well as an absorptivity. Since the third-layer mat has a skin (thin film) on the lower surface and is a slightly rigid polyurethane porous body having a foam density (35 to 45), the absorbed moisture is difficult to escape and has water retention. Kept. The underlay mat (lower mat) thus absorbs the moisture of the upper mat (surface mat) quickly by combining three different functions, but the absorbed moisture returns to the upper mat (surface mat). However, since it has difficult properties, it is possible to maintain the drying property of the upper mat (surface mat). In addition, because of the action of wiping the foot with the weight applied, and the wiping of the foot, especially the first layer mat contains a lot of air, so the urethane foam (polyurethane porous body) that can be stepped on with the foot is consolidated (compressed). The air passing through the upper mat (surface mat) out of the volume of air dispersed in the surroundings accelerates the drying of the upper mat (surface mat), and conversely when the feet are removed from the mat. From the direction of the air, the volume of air in which the urethane foam (polyurethane porous body) returns to the original passes through the upper mat (surface mat). Since the amount of air that passes through this upper mat (surface mat) increases as you step on it, it is possible to maintain the dryness of the upper mat (surface mat) even if there are many users. It is a dry mat.

According to the present invention, the upper mat (surface mat) and the urethane foam (polyurethane porous body) three layers using synthetic fibers (drying, antibacterial agent blend) with reduced water retention as much as possible as a material that promotes natural drying Foot-drying mat consisting of an underlay mat (lower mat) with a structure (moisture absorption layer with air layer, moisture barrier layer, moisture absorption / water retention layer) converts human foot pressure energy generated at the entrance to the bathroom into drying energy And, as a mat with improved drying performance without using electricity or environmentally, it breaks through all the concepts of traditional mat drying, such as maximizing the natural drying of the upper mat (surface mat). Considering the global environment, such as using a dry mat to wipe the feet leads to eco-friendliness.

Further, in parallel with the absorption / diffusion function of the upper layer mat (surface mat), water movement is promoted to the lower layer mat (underlay mat) each time it is stepped on, and the drying property of the upper layer mat (surface layer mat) is improved. Furthermore, when stepped on, the repulsive force of the lower layer mat (underlay mat) is generated, and the air around the stepped floor is diffused into the lower layer mat (underlay mat) and upper layer mat (surface mat), further drying the upper and lower layer mats. Facilitate.

The foot-wiping drying mat of the present invention saves the cost of the introduced warm bath facility and linen supplier in charge of cleaning (higher drying performance and reduction in the number of used sheets can reduce fuel cost by about 75%), and CO ₂ accompanying the reduction in the number of washing sheets. It can also be used as a product to combat global warming.

It is sectional drawing of the foot-wiping dry mat which concerns on this invention. It is state explanatory drawing at the time of use of the foot-wiping dry mat which concerns on this invention. It is explanatory drawing of the state which returned to the standby state from the state of FIG. The top view of the 2nd layer mat 12 of the foot wipe drying mat concerning the present invention is shown. FIG. 5 is a VV arrow cross-sectional view of the second second-layer mat 12 shown in FIG. 4. FIG. 5 is a rear view (back view) of the second second-layer mat 12 shown in FIG. 4.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

A foot-wiping dry mat 1 of the present invention shown in FIG. 1 is a laminated type composed of an upper mat (surface mat) 2 and an underlay mat (lower mat) 4. The upper mat (surface mat) 2 is a dobby weave with a soft and gentle texture with a soft feeling of unevenness, using anti-bacterial processed and high-water-repellent synthetic fiber constituent yarns, using a woven fabric in a predetermined shape, or It consists of a woven fabric of any one of a waffle weave and a pile weave. Furthermore, the upper mat (surface mat) 2 is a synthetic fiber with reduced water retention as a material that promotes natural drying and uses moisture-drying and antibacterial-blended fibers. Each time, the moisture transfer is promoted to the underlying mat (lower mat) 4 and the drying of the upper mat (surface mat) 2 is further promoted.

The upper layer mat (surface layer mat) 2 is an antibacterial acrylic fiber with reduced water retention as a synthetic fiber forming the constituent yarn, and is any one of dobby weave, waffle weave, or pile weave. Since it is made of woven fabric, moisture movement is promoted to the lower mat (lower mat) 4 every time it is stepped on by a person, and drying of the upper mat (surface mat) 2 is further promoted.

The underlay mat (lower mat) 4 is made of a polyurethane porous body having three different foam densities and forming a first layer mat 5, a second layer mat 7, and a third layer mat 9 from above. For example, the first-layer mat 5 is a polyurethane porous body having a foam density of 35 to 40, the second-layer mat 7 is a polyurethane porous body having a foam density of 50 to 60, and the third-layer mat 9. Is composed of a polyurethane porous body having a foam density of 35 to 45.

The shape of the first-layer mat 5 constituting the underlay mat (lower layer mat) 4 is such that the concave portions 5a and convex portions 5b having a relatively large radius of curvature are arranged on the entire surface adjacent to each other. A concave portion 6a and a convex portion 6b having a small radius of curvature are arranged adjacent to each other. The convex portion 5 b on the front surface is in contact with the back surface side of the upper layer mat (surface layer mat) 2, and the space between the back surface side of the upper layer mat (surface layer mat) 2 and the concave portion 5 a having a relatively large curvature radius of the first layer mat 5. Air is stored in The convex portion 6b on the back surface of the first-layer mat 5 is in contact with the surface of the second-layer mat 7 described later, and the concave portion 6a having a relatively small radius of curvature of the first-layer mat 5 and the second-layer mat 7 described later. Air is also stored in the space with the surface. When the foot-wiping dry mat 1 is in use, moisture is forcedly dispersed and moved in the direction of the surrounding arrow by the user's foot pressure (step pressure) (see FIG. 2).

By the way, urethane foam (polyurethane porous body) that is stepped on with a foot is compacted (compressed), and the air and moisture passing through the upper mat in the volume of air dispersed in the surroundings are described with reference to FIG. The moisture in contact with the surface of the upper mat 2 is transmitted through the upper mat 2 due to the synthetic fiber having a low water holding power, and the moisture is the first mat of the underlay mat (lower mat) 4. 5 is absorbed by the polyurethane porous body having a density of 35-40. Then, when a person rides on the dry mat 1 and foot pressure is applied to the polyurethane porous body, which is the first mat 5 constituting the underlay mat (lower mat) 4, through the upper mat 2, the upper mat 2 Moisture released from the water further passes through the polyurethane porous body of the second layer mat 6 together with air, and further moves to absorb and retain water in the third layer mat.

In the foot-wiping dry mat 1 of the present invention, the first-layer mat 5 is a polyurethane porous body having a low foam density (35 to 40), and therefore has excellent absorbability and a large amount of air layer space. Therefore, the concave portion 5b and the convex portion 5a and the concave portion 6b and the convex portion 6a on the back surface are formed on the front surface. Since the second-layer mat 7 is a polyurethane porous body having a slightly high foam density (50 to 60), it has moisture barrier properties as well as absorbability. The third-layer mat 9 is a slightly porous polyurethane porous body having a skin (thin film) 9b formed on the lower surface of the main body 9a of the third-layer mat and having a foam density (35 to 45). Therefore, the absorbed moisture is difficult to escape and water retention is maintained. In particular, the second layer mat 7 is a polyurethane porous body having a slightly higher foam density (50 to 60) than the foam density of the first layer mat and the third layer mat, and is stepped on from above. At that time, air and moisture are forced to pass through the second-layer mat 7 and sent to the third-layer mat 9. Conversely, when the stepped force (stepping force) is removed and the deformed foot-wiping dry mat 1 is restored to a flat state, the slightly higher foam density (50) of the second-layer mat 7 (50). -60) becomes resistance, and reverse inflow of air and moisture from the direction of the third layer mat 9 is prevented, and the restoration of the flat state is caused by air from the surrounding direction (mainly at the upper part) as described later. It is made by flowing into the foot-drying dry mat 1.

The underlay mat (lower mat) 4 absorbs moisture of the upper mat (surface mat) 2 quickly by combining three different functions in this way, but absorbs the absorbed moisture into the upper mat (surface mat) 2. Is difficult to reverse, so that the drying property of the upper mat (surface mat) 2 can be maintained. In addition, because of the action of wiping the foot with the weight applied, and the wiping of the foot, the first-layer mat 5 in particular has a large amount of air, and therefore urethane foam (polyurethane porous material) that receives the force (stepping pressure) struck by the foot. The air passes through the upper mat (surface mat) 2 out of the volume of air that is compacted (compressed) and is dispersed in the surroundings, thereby promoting the drying of the upper mat (surface mat) 2. Then, when the foot that has been stepped on to change the foot is removed from the foot wiping dry mat 1, the foot wiping dry mat 1 deformed by the stepping pressure is restored to a flat state as shown in FIG. Therefore, as shown in FIG. 3, conversely, air passes through the upper mat (surface mat) 2 and flows into the underlay mat (lower mat) 4. That is, air passes through the upper mat (surface mat) 2, further passes through the first mat 5 of the underlay mat (lower mat) 4, further passes through the second mat 7, and the third mat. Reach 9 and stop. In this state, air is wiped from the surrounding direction (mainly at the upper part) into the drying mat 1, and the volume of air in which the urethane foam (polyurethane porous body) returns to the original is the upper mat (surface mat) 2. Passes through the first layer mat 5 of the underlay mat (lower layer mat) 4, further passes through the second layer mat 7, and reaches the third layer mat 9 to stop (see FIG. 3). ). In this manner, in the foot-drying mat 1, the amount of air passing through the upper mat (surface mat) 2 increases as the user steps on the upper mat (surface mat). 2) The drying property of 2 can be maintained.

  FIG. 4 shows a plan view of a second second-layer mat 12 that can be arranged instead of the second-layer mat 6 constituting the underlay mat (lower layer mat) 4, and FIG. 5 is shown in FIG. FIG. 6 is a cross-sectional view of the second second-layer mat 12 taken along the line VV, and FIG. 6 is a rear view (rear view) of the second second-layer mat 12 shown in FIG. The configuration of the second second-layer mat 12 will be described with reference to FIGS. 4, 5, and 6. The second second-layer mat 12 includes a second second-layer mat body 13 having a plurality of cylindrical holes (a cylindrical shape or a polygonal column shape) 13a having a predetermined size on the upper surface side, and a lower surface side ( On the back surface side, a surface corresponding to the plurality of cylindrical holes 13a and having a size covering the lower end surface of the cylindrical hole 13a, may be a plurality of circular arc cuts (polygonal side cuts may be used). A second thin film (second skin) having a surface surrounded by Air and moisture that have passed through the upper layer mat (surface mat) 2 and further passed through the first mat 5 of the underlay mat (lower layer mat) 4 are guided to the plurality of cylindrical holes 13a to form a plurality of arcs. After passing through the cut, the third layer mat 9 is reached and stopped. However, when air and moisture are to flow backward from the third-layer mat 9 toward the upper surface of the second-layer mat 12, a plurality of arcs each having a size covering the lower end surfaces of the plurality of cylindrical holes 13a. Each of the surfaces surrounded by the incisions (polygonal side incisions) serves as a check valve, each covering the lower end surface of the plurality of cylindrical holes 13a and blocking air and moisture. Demonstrate sex. Therefore, in the foot wipe drying mat 1 of the present invention, the second two-layer mat 12 can be used in place of the second-layer mat 6 constituting the underlay mat (lower mat) 4 even if the second two-layer mat 12 is used. The eye mat 12 has a moisture barrier property as well as an absorptive property in the same manner as the second layer mat 7, and the amount of air passing through the upper layer mat (surface mat) 2 in the foot wipe dry mat 1 is as follows. Since the number of steps increases as the user steps on, the drying property of the upper mat (surface layer mat) 2 can be maintained even if the number of users increases. In the second second-layer mat 12, the portion of the surface surrounded by the cuts of a plurality of arcs of the second thin film (second skin) provided on the lower end surface of the second second-layer mat body 13 Is a non-return between the operation of closely contacting the lower end surfaces of the plurality of cylindrical holes 13a and the operation of opening the plurality of circular arc incisions as communication holes apart from the lower end surfaces of the plurality of cylindrical holes 13a. In order to have a valve function, the surface surrounded by the cuts of the plurality of arcs can freely move in a flattened manner, and the other second thin film (second skin) portion is the second second-layer mat body 13. It is assumed that it is fixed to the lower end surface of the substrate by adhesion or welding.

  Although the embodiment of the present invention has been described above, the scope of the present invention is not limited to this, and it goes without saying that various modifications can be made without departing from the scope of the present invention.

The present invention can be used for inns / hotels, day-trip hot spring facilities, sports clubs and the like nationwide.
