[Prior art]

 2. Description of the Related Art Conventionally, a dust control (shoe-wiping) mat has been widely used in order to prevent outdoor dust from adhering to the inside of a shoe by adhering to the sole or the like. This shoe-cleaning mat is lent to customers for a limited period of time, and is laid and used at entrances and entrances of stores and offices where people can enter and exit, and then collected, washed, treated with oil, etc. It is being operated by a rental system that is regenerated by the company and is rented to consumers again.

As such a rental mat, for example, as described in Japanese Patent Publication No. 59-7450, a separate type mat in which a piled mat is detachably attached to a rubber frame base, It is known as an integrated type in which a rubber sheet is fixed to the back side of a piled mat, but the latter type tends to be preferred in terms of stability and appearance when laid.

[0004]

[Problems to be solved by the device]

 Shoe-wiping mats have a matte surface consisting of tufted pile threads on the base cloth on one side of the base cloth.However, in conventional mats, the pile threads on the matte surface have fine dust etc. It is effective when there is little adherence, but when dust is sticking to the sole of the shoe and when there is much adherence, it needs to be repeatedly rubbed to remove dirt, and it tends to take some effort to remove dirt. In addition, the pile yarn tends to lie down during repeated use, and the scratch resistance of dirt such as dust tends to decrease during repeated use, washing and regeneration. In addition, when cleaning after use, dust, lint, etc. are less likely to get dirty, and in particular, lint tends not to fall cleanly and remain attached.

Therefore, the object of the present invention is to easily wipe off dirt such as dust adhering to shoe soles and the like as compared with a conventional mat, and it has a better wiping effect, and is repeatedly used and washed in a rental system. The present invention is to provide a shoe-wiping mat that has excellent durability and has a good function of wiping off dirt such as dust for recycling such as recycling.

Another object of the present invention is to provide a shoe-cleaning mat which has an excellent effect of wiping off dirt such as dust adhering to shoe soles and the like, and is also excellent in cleanability in repeated use, washing and recycling for recycling. To provide.

[Means for solving the problem]

 According to the present invention, a shoe wiping mat is characterized in that a pile area of nylon monofilament having a single yarn fineness of 30 to 800 denier and a pile area of nylon multifilament crimped yarn are alternately provided in an adjacent relationship. Will be provided. In the present invention, the stitch density of the pile yarn in the pile area of the nylon monofilament is preferably in the range of 20 to 2000 per unit square inch. Further, it is preferable that the pile yarn in the pile area of the nylon monofilament is composed of a bundle of 1 to 500 nylon monofilaments.

[0008]

[Action]

 The shoe-wiping mat of the present invention comprises a pile area of nylon monofilament (hereinafter simply referred to as “monofilament”) and a pile of nylon multifilament crimped thread whose pile surface has a single yarn fineness of 30 to 800 denier. A distinctive feature is that areas (hereinafter referred to as area B) are provided adjacent to each other in an adjacent relationship.

As described above, the shoe-wiping mat is roughly classified into an integrated mat and a separate mat, but the present invention can be applied to either of them.

In the shoe-wiping mat of the present invention (hereinafter simply referred to as “mat”), the nylon monofilament that constitutes the pile yarn in the area A of the pile surface is quite thick with a single yarn fineness of 30 to 800 denier and is conventionally used for mats. Compared to fibers such as multifilaments and nylon multifilament crimped yarns in the B area of the pile surface, it is more rigid and has excellent resilience and resilience to bending and elasticity, and acts like a brush, maintaining the matte texture. ing. It also has excellent wear resistance and dust resistance.

When wiping a shoe sole or the like (hereinafter referred to as a shoe sole) with a mat, the shoe bottom is brought into pressure contact with the mat due to foot pressure (the load of the human body on the foot), but there is a degree of consolidation in areas A and B. Differently, the B area tends to be dented, and the pile recoverability when released from foot pressure is faster in the A area than in the B area. Moreover, the waist is standing strong. Therefore, when the shoe sole is wiped with a matte surface, the area A protrudes from the area B to scrape off the dust adhering to the shoe sole, which is synergistic with the conventional wiping off. Thus, it becomes easier to remove dust on the sole of the shoe as compared to the conventional mat, and the dust removal efficiency is significantly improved.

The mat pile surface has an A area and an B area, and the A area is always strongly affected by foot pressure, but it has excellent impact resilience, so that it is suitable for repeated use, cleaning, and recycling for recycling. There is almost no change (decrease) in pile height, and the change in pile height in area B is also small, and the dust removal effect is long-term dust removal during repeated use, cleaning and recycling. Good property can be maintained.

Further, the nylon monofilament in the area A is wear-resistant and strong against abrasion, and is unlikely to be cut or lint, but the nylon multifilament crimped thread in the area B also gives a matte feel and is repeatedly used. It has the feature that it does not unravel easily when washed and regenerated, and that it is difficult to remove hair.

Therefore, in repeated use such as repeated use, washing, and recycling, it is durable against abrasion, has excellent washability, and the generation and adhesion of lint and the like are suppressed and reduced. Further, since the area A is a monofilament, it is particularly excellent in cleanability.

By designing the arrangement of the A area and the B area on the pile surface and changing the coloring in the A area and the B area or in each area, mats of various designs can be obtained, and the A area and the B area can be obtained. Because of different textures, it is possible to provide various textures and design mats that can be adapted to places of use. In the present invention, the nylon monofilament is important in that it has a single yarn fineness within a range of 30 to 800 denier, has rigidity, has a supple texture, and has good elasticity and rebound recovery property.

If it is below the above range, the waist becomes weak and the synergistic effect of scraping off dirt such as dust is reduced. On the other hand, when the amount exceeds the above range, the synergistic effect of scraping off the dirt cannot be expected so much, and the texture of the mat is deteriorated.

When the nylon monofilament is bundled (using no sizing agent) in the range of 1 to 500 to form a pile yarn, the dust collecting property, elasticity, and rebound recovery property are further improved. Even in this case, the pile yarn has a sharp tip, so that the texture is good and the washability is also good. Further, it is preferable that the stitch density in the pile area of the nylon monofilament is 20 to 2000 per unit area square inch in order to exert the above-mentioned effect.

[Preferred Embodiment of the Invention]

 An example of the shoe-wiping mat of the present invention is shown in FIG. 1. The mat is fixed to a base cloth 1, tufted mat pile yarns 2 on the base cloth 1, and non-pile surface 3 of the base cloth. Made of rubber backing 4 made.

As for the pile surface 5 of the mat of the present invention, as shown in FIG. 2 showing an example thereof, a pile area (A area) 6 of nylon monofilament having a single yarn fineness of 30 to 800 denier and a nylon multifilament crimped yarn. The pile areas (B areas) 7 are alternately arranged adjacent to each other.

As the matte base cloth 1, any material such as woven cloth, knitted cloth, and non-woven cloth is used. Usually, synthetic fiber is used, but natural fiber, human silk, inorganic fiber, carbon fiber, metal fiber or the like or a combination thereof can also be used.

As the synthetic fiber, any synthetic fiber, for example, polyester fiber, polyamide fiber, acrylic fiber, vinylon fiber, polypropylene fiber, ultra high molecular weight polyolefin fiber, aromatic polyamide fiber, etc. can be used, and these are used alone. However, you may use 2 or more types. High molecular weight thermoplastic polyesters, especially thermoplastic copolyesters based on polyethylene terephthalate or ethylene terephthalate, are preferably used.

A plain weave is usually sufficient as the woven fabric, but a twill weave or another weave may be used. As the knitted cloth, gauze, gauze, or a net-like material having a small knitting density is used. Further, a woven fabric, a knitted fabric, etc. and a non-woven fabric can be used in combination. The basis weight of the base cloth varies depending on the weight of the mat and the like, but it is generally preferable to be in the range of 100 to 500 g / m ² .

The nylon monofilament having a single yarn fineness of 30 to 800 denier used for the pile yarn in the area A 6 is made of colored nylon. Nylon monofilament has a single yarn fineness in the range of 30 to 800 denier, which improves the abrasion resistance, elasticity (repulsion recovery) and dust trapping property (especially the scraping synergistic effect) of the pile and mat. It is important for maintaining the texture of. It also provides flexibility and elasticity (rebound recovery) while strengthening the waist, and improves dust collection and texture.

When the single yarn fineness is below the above range, the elasticity is reduced and dust is scraped off, and the synergistic effect cannot be sufficiently exerted. When the single yarn fineness is above this range, the dust collecting property is not significantly improved. On the contrary, the texture of the mat will be impaired.

The nylon monofilament 8 is used as the pile yarn 9 in a substantially non-twisted state by bundling 1 to 500 filaments as shown in FIG. The nylon monofilament 8 is flat in the figure, but non-flat ones and various cross-sectional shapes can be used. It can also be used in a properly twisted state.

As the colored nylon, either undiluted dyed nylon or dyed nylon can be used, but undiluted dyed nylon is particularly preferable because it is excellent in light resistance, fading resistance, washing fastness and the like. As the nylon, a general-purpose nylon such as nylon 6 (polycaprolactam) or nylon 66 (polyhexamethylene adipamide) is usually used. In concentrated dyed nylon, coloring agents such as pigments and dyes are mixed in nylon.For example, adding the coloring agent before polycondensation, adding it at the time of polycondensation, or masterbatch in nylon after polymerization. A method of mixing a colorant by a method is appropriately adopted.

As the nylon multifilament crimped yarn (hereinafter referred to as BCF nylon yarn), colored nylon such as undyed nylon and dyed nylon can be used, but undyed nylon is preferable.

As the multifilament single yarn, those having various cross-sectional shapes such as a circular type, a cocoon type, a trilobal type, a four-leaf type, a triangular type and a square type are used. A filament having a single fiber diameter of generally 10 to 200 μm, preferably 20 to 100 μm is used from the viewpoint of pile fluffing, dust collecting property, and texture. BCF nylon yarns generally have a total fineness in the range of 300 to 30,000 denier, especially 500 to 20,000 denier.

Well-known methods are used as the method for driving the nylon monofilament and the BCF nylon thread into the base fabric, the method for cut pile, etc., the gauge is 2 to 20 (per inch), and the stitch is 2 to 20. The range (per inch) is good. The length of the pile to be implanted is generally in the range of 4 to 30 mm, preferably in the range of 5 to 20 mm. A cut pile is used as the pile type, but a loop pile may be used for the BCF nylon yarn. The pile length may be constant or different from each other, for example, the pile length in the area A may be cut longer than the pile length in the area B, or the pile length in the area A may be high cut and the pile length in the area B may be low loop. .

As the sheet which becomes the rubber backing 4, various elastomer polymers such as acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), polybutadiene (BR), polyisoprene are used. (IIB), butyl rubber, natural rubber, ethylene-propylene rubber (EPR), ethylene-propylene-diene rubber (EPDM), polyurethane, chlorinated polyethylene, chlorinated polypropylene, soft vinyl chloride resin and the like can be used. From the viewpoint of oil resistance, weather resistance, etc., acrylonitrile-butadiene rubber (NBR) is preferable. In forming the rubber sheet, a compounding agent known per se, for example, a sulfur-based or organic vulcanizing agent, a vulcanization accelerator, a softening agent, an antioxidant, a filler, a dispersant, a plasticizer, a coloring agent. And the like can be added in a known amount.

In the production of the integrated mat, the above rubber composition is kneaded by using a roll, a Banbury mixer, etc., and the composition is formed into a sheet. Heating and pressurization are performed therein to simultaneously perform adhesion and vulcanization. In order to enhance the adhesion between the rubber sheet and the base fabric, latex of the same type of rubber as the rubber sheet is applied to the non-pile side of the base fabric, or an adhesive or adhesion promoter such as ethylene vinyl acetate copolymer is applied. It can be applied in advance. The basis weight of the rubber sheet is preferably in the range of 400 to 5000 g / square meter, and it is preferable that the both are integrated so that the edge of the rubber sheet slightly extends outside the edge of the base cloth. The vulcanization adhesion is performed at a temperature of 130 to 190 ° C. and a pressure of 1 to 20 kg / cm ² (gauge pressure).

When soft vinyl chloride resin is used as the backing sheet, plastisol of vinyl chloride resin is applied to the non-pile surface of the pile-implanted base fabric, and then the plastisol layer of vinyl chloride resin is gelated by heating. Just do it. When polyurethane is used as the backing sheet, the two-component type polyurethane resin composition is applied to the non-pile side of the pile-implanted base fabric, and then the polyurethane resin composition layer is cured by heating or the like. Just do it.

The pile yarn of the mat of the present invention has a function of adsorbing and retaining dusts adhering to a shoe sole or the like. In order to further enhance this action, the pile yarn can be coated or impregnated with a dust adsorbing oil agent. Examples of the dust-adsorptive liquid include fluid paraffin, mineral oil such as spindle oil, alkylbenzene oil, diester oil, castor oil, synthetic oil, vegetable oil-based oil agent, JP-B-53-1019 and JP-B-53- Examples thereof include the aqueous dust adsorbents described in JP-A-37471. The coating amount of the adsorbent is generally in the range of 5 to 70 g / m ² .
