[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat used for wiping shoes and the like. More specifically, the mat pile yarn has a remarkably improved napped property, a rubbing property of a shoe sole and the like, and a dust collection. And a mat which is remarkably excellent in holding performance.

[0002]

2. Description of the Related Art Conventionally, dust control mats (for wiping shoes) have been widely used to prevent outdoor dust from adhering to shoe soles and the like and invading indoors. This dust control mat is lent to customers only for a certain period of time, laid at places such as entrances where people enter and exit, used, collected, regenerated by washing, oil treatment, etc. It is operated by a rental system that is lent to.

[0003] Rental mats include Japanese Patent Publication No. 59-74.
No. 50, a separate type in which a mat having a pile is detachably attached to a rubber frame-like base, and a pile type, as described in JP-A-62-137029. An integrated type in which a rubber sheet is fixed to the back side of a certain mat is known.

[0004] These mats, whether of the separate type or the integral type, are constructed by embedding a pile yarn on a fiber base material such as a woven or non-woven fabric by means of tufting or the like, and forming a pile. An elastomer backing on the stitched surface.

[0005]

These shoe wiping mats repeat a number of rental cycles, including use, cleaning, and regeneration, and increasing the number of rental cycles requires the use of a shoe wiping mat. It is highly desirable in reducing the service cost of the service. However, in the known shoe wiping mats, the mat pile tends to sleep more and more as the rental number increases, and the pile pile-up property gradually decreases. When the pile nurturing property is reduced, the appearance and texture of the mat are reduced, and not only the commercial value is impaired, but also the bulkiness of the piles is lost, and the dust collecting property and the dust holding property are also reduced.

Accordingly, an object of the present invention is to solve the above-mentioned drawbacks of the conventional mat, remarkably improve the napped property of the mat pile yarn, and improve the rubbing property with the shoe sole and the dust collecting and holding performance. Another object of the present invention is to provide a rental shoe wiping mat which is remarkably excellent and has a protective effect on mat pile yarn.

[0007]

Means for Solving the Problems The pile raising property of the pile of the present invention .
The improved shoe wiper mat for rental is a densely woven lower tissue, a mesh-woven upper tissue, an intermediate tissue that connects the lower tissue and the upper tissue, and is interwoven between them. A three-dimensional woven fabric comprising a base fabric, and a pile yarn having a height substantially equal to the height of the upper fabric is planted in the lower fabric of the base fabric.

[0008]

According to the present invention, a three-dimensional woven fabric is used as the base fabric of the mat. The three-dimensional woven fabric connects (i) a densely woven lower tissue, (ii) a mesh-like or densely woven upper tissue, and (iii) connects the lower and upper tissues to each other. It is made up of an intermediate organization that is woven.

The lower structure is a portion where the pile yarn is implanted by tufting or the like and serves as a support for the entire mat. However, the lower structure is densely woven, has high strength, and has dimensional stability. Is also large. The upper structure becomes the upper surface of the mat together with the tip of the pile yarn at the time of use, and contacts the bottom surface of the shoe to perform a wiping action for removing dust. The intermediate tissue keeps the lower tissue and the upper tissue integrally and mechanically firmly connected, and keeps the upper tissue at a certain height relative to the lower tissue. Further, the intermediate structure works in cooperation with the upper structure so as to significantly improve the pile raising property of the pile yarn as described later.

In the present invention, the three-dimensional fabric is used as a base fabric,
It is a remarkable feature that a pile yarn reaching almost the same height as the upper structure is implanted in the lower structure of the base fabric. The pile yarn implanted with respect to the lower tissue is accommodated in a mesh-shaped upper tissue in a mesh opening (chamber) partitioned by cells of a middle tissue vertically connected to the upper tissue, and passes through the cell. As a result of being prevented from falling down sideways,
The pile raising is significantly improved, which offers the advantage that it is not lost when the number of rental cycles is increased.

The pile yarn is made of delicate fiber to increase the surface area in order to improve dust retention.
In particular, the cut pile has a free end, so the waist is weak, but in the present invention, the three-dimensional fabric is mechanically strong in the three-dimensional direction and has a strong waist structure. , Sufficient uprightness can be guaranteed. This is also the case if the pile is wet with rain.

In addition, since the height of the pile yarn is set to be substantially the same as the height of the three-dimensional fabric, when the mat is stepped on a shoe sole or the like, the upper structure of the three-dimensional fabric retreats downward. Therefore, the tip of the pile yarn effectively contacts the surface of the shoe sole or the like, and when rubbing with the shoe sole or the like, not only the tip of the pile thread but also the upper structure of the three-dimensional fabric is effectively rubbed against the shoe sole. As it is involved in rubbing, it effectively removes dust and mud,
In addition, the collection and holding of the dusts on the pile yarn are effectively performed.

Further, in the present invention, even when a luggage cart or the like passes on the mat, there is an effective effect that the three-dimensional fabric protects the pile yarn and prevents the pile yarn from being damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 (perspective view) and FIG. 2 (enlarged sectional view taken along line AA in FIG. 1) showing a three-dimensional fabric 1 used as a base fabric in the present invention, the three-dimensional fabric 1 , An upper tissue 3 and an intermediate tissue 4 connecting the two. The lower tissue 2 is densely woven, and the upper tissue 3 is woven in a mesh shape. In this specific example, the mesh net is hexagonal, but may of course be square or other shapes.

The intermediate structure 4 of the three-dimensional fabric 1 connects the lower structure 2 and the upper structure 3, and the yarn constituting the intermediate structure 4 is interwoven with the lower structure 2 and the upper structure 3. However, in order to maintain these three-dimensional structures at high strength and to withstand even when a compressive force is applied by being stepped on with shoes, etc., and to make the rebound resilience and resilience high, In addition, it is preferable to use high-strength high-strength fibers.

For this reason, in the present invention, the fibers constituting the intermediate portion structure 4 have a single yarn fineness of 5 to 500 denier,
In particular, a monofil (monofilament similar to Tegs) 5 having a denier of 20 to 200 is used. This monofil is desirably made of polyamide fibers such as nylon 6, nylon 6, 6 in terms of strength and compression elasticity.

The lower structure 2 supports the whole of the three-dimensional fabric 1 serving as a mat, and since the pile yarn is implanted by tufting or the like, the lower structure 2 is strong in terms of strength, and is further washed. Even if the reproduction is repeated, the structure must be resistant to fraying and running. Generally, the lower structure 2 includes a warp chain knit made of a multifilament yarn or a spun yarn,
And the knitting in the weft direction made of the monofil, and the knitting in the weft direction is tangled with the knitting in the warp direction and has a knitting structure for connecting these.

The upper structure 3 serves as a mat surface in contact with a shoe sole or the like together with the tip of a pile yarn described later.
In the mesh-like upper structure, a warp chain knitting generally made of a multifilament yarn or a spun yarn is branched and merged to form a mesh-like net. The knitted structure in which the monofil of the intermediate part structure 4 is entangled in the weft direction also for the chain knitting of the upper structure. In this specific example, the chain knitting in the warp direction in the lower tissue 2,
The chain knitting in the warp direction in the upper structure 3 is independent of each other, and both are connected only between the upper and lower portions by the monofil 5 of the intermediate structure 4.

The monofils 5 of the intermediate structure extend vertically along the contour of the mesh of the upper structure, and the monofils 5 are aligned substantially parallel to the vertical direction. Thus, after the monofil 5 constituting the intermediate structure 4 is entangled with the warp chain knitting of the upper structure 3, it passes through the intermediate structure 4 and forms a weft knitting while tangling with the warp chain knitting of the lower structure 2. It is understood that the knitted structure is repeated through the intermediate structure 4.

It will be understood that there is an opening 6 between the meshes in the upper tissue 3, through which the lower tissue 2 is exposed.

The three-dimensional fabric used in the present invention is known per se, and is generally woven by Russell knitting using a plurality of reeds (front) in a warp direction and a reed (back) in a weft direction. You.

As the yarn for the lower structure and the yarn for the upper structure, a spun yarn or a multifilament yarn composed of one or more of cotton fiber, rayon fiber, polyvinyl alcohol fiber, acrylic fiber, nylon fiber and other synthetic fibers. Can be used. These yarns generally should have a total fineness of 20 to 1600 denier.

In the three-dimensional woven fabric, the height between the upper and lower structures is preferably in a range of generally 2 mm to 30 mm, particularly 5 mm to 15 mm. When the upper structure is a mesh, the opening size is an average value. Is suitably in the range of 0.1 mm to 5 mm, particularly 1 mm to 3 mm. Other conditions for weaving are not particularly limited, but the cell interval of the intermediate composition is preferably in the range of 1 mm to 15 mm from the viewpoint of the mat as a mat, shape retention, and durability.

In the present invention, the three-dimensional fabric 1 is used as a base fabric, and pile yarns are planted in a lower fabric 2 of the base fabric to form a pile reaching almost the same height as the upper fabric.
If necessary, a backing layer is formed on the pile stitch surface.

In FIG. 3 (perspective view) and FIG. 4 (enlarged cross-sectional view taken along the line CC in FIG. 3) showing an example of the mat of the present invention, the mat has a base cloth 1 made of a three-dimensional woven fabric and a base cloth. It comprises a pile yarn 7 implanted by tufting or the like, and an elastomer backing layer 9 provided on the side of the stitch 8 of the base fabric.

That is, according to the present invention, the cell 6 (FIG. 1) divided by the cell wall of the upper tissue 3 and the intermediate tissue 4 has:
The planted pile yarns 7 are accommodated separately, and the pile yarns 7 are provided so as to reach almost the same height as the upper structure 3. It is exposed to. Of course, the tip of the pile yarn 7 is
May protrude slightly above the surface of the upper tissue 3, or conversely, may protrude slightly below the surface of the upper tissue 3.

In the specific example shown in the cross-sectional view of FIG. 4, the pile yarn 7 is shown as being tufted only in the cell 6, but tufting is performed under such controlled conditions. Alternatively, tufting may be performed on the intermediate structure 4 without any problem. The reason is that the intermediate structure 4 has a space through which the pile yarn passes.

As the pile yarn to be driven into the base cloth, a spun yarn or a multifilament yarn made of one or more of cotton fiber, rayon fiber, polyvinyl alcohol fiber, acrylic fiber, nylon fiber and other synthetic fibers can be used. it can. The pile thread can be implanted by any known method such as tufting, sewing, embroidery, and hook. In particular, it is a remarkable advantage of the present invention that the base cloth is not damaged even when a pile of extremely thick denier, which has not been hitherto made, is driven by a hook. The pile length to be implanted is generally 3mm to 15m
m, the type of pile may be a cut pile or a loop pile, or may be crimped, may not be crimped, and the pile length may be constant or different from each other,
For example, a high cut-low loop or the like may be used. The fineness of the pile can also vary greatly, from 100 denier to 40
It is in the range of 00 denier. The pile driving conditions may be known, and the gauge may be in the range of 2 to 20 (per inch) and the stitch may be in the range of 2 to 20 (per inch).

In producing the integrated mat, the above rubber composition is kneaded using a roll, a Banbury mixer, etc., the composition is formed into a sheet, a tufted mat is superimposed on the sheet, and the sheet is placed in a pressure mold. By applying heat and pressure, bonding and vulcanization are performed simultaneously. To enhance the adhesion between the rubber sheet and the base cloth, apply the same type of rubber latex as the rubber sheet to the non-pile surface of the base cloth, or apply an adhesive or adhesion promoter such as ethylene-vinyl acetate copolymer in advance. You can keep. The basis weight of the rubber sheet is 400 to 5
2,000 g / square meter, and the two are preferably integrated such that the edge of the rubber sheet slightly protrudes from the edge of the base cloth. Vulcanization bonding is preferably performed at a temperature of 140 to 190 ° C. and a pressure of 0.5 to 20 kg / cm ² .

When a soft vinyl chloride resin is used as the elastomer, a plastisol of the vinyl chloride resin is applied to the non-pile surface of the pile-implanted base fabric, and then the plastisol layer of the vinyl chloride resin is gelled by heating. Good. When polyurethane is used as the rubber sheet, a two-pack type polyurethane resin composition is applied to the non-pile surface of the pile-implanted base fabric, and then the polyurethane resin composition layer is cured by heating or the like. Good.

The rubber sheet used in the present invention is a low-magnification foam when integrated with the base cloth, in order to completely suppress the generation of ripples during repeated washing. desirable. The expansion ratio of the rubber sheet is
In general, it should be in the range of 1.2 to 5.0 times, especially 1.5 to 4.0 times. The foaming of the rubber sheet can be performed by adding a chemical foaming agent which decomposes at the vulcanization or curing temperature to the composition for forming the rubber sheet. Of course, foaming may be performed by impregnating or dispersing a gaseous foaming agent in the composition in advance.

The pile yarn of the mat of the present invention has a function of adsorbing and retaining dust adhering to shoe soles and the like. In order to further enhance this effect, the pile yarn may be coated or impregnated with a dust-adsorbing oil agent.
