It protrudes as a locking part for locking the floor surface to be laid.

  Further, the inventor laminated the fibrous sheet 15 containing the heat-adhesive fiber 16 as a constituent fiber on the knitted fabric 12 and entangled them in the carpet 1, whereby the heat-adhesiveness of the fiber sheet 15 is obtained. The fibers 16 are entangled and integrated with the knitted fabric 22, and the heat-adhesive fibers 16 contained in the fiber sheet 15 are heat-sealed by heat treatment thereon to become a resin component, and the fiber sheet 15 is hardened. Similarly, the heat-adhesive fibers 16 that are intertwined with the knitted fabric 12 are also heat-sealed to become a resin component, improving the integrity of the two, and the loop-shaped warp 14 cut from the knitted fabric 12 is also a resin component and its base (root portion) is It has also been proposed that it is hardened, the strength of the cut end 14a of the warp yarn 14 is increased, and the bite to the floor surface and the slip prevention property are also improved.

  Many rugs having a similar structure have been proposed thereafter (see, for example, Patent Documents 3 and 4). That is, as shown in FIG. 9, it comprises a net-like raschel knitted fabric 22 having a loop pile, the loop pile of the raschel knitted fabric is cut in the vicinity of the top, and the cut end engages the floor surface on which the rug 21 is laid. A backing material 22 protruding as a locking portion to be stopped is attached to the back surface of the rug 21.

  Hereinafter, the lining material of the rug of the present invention, the rug using the same, and the mat for an automobile will be described in more detail with reference to the drawings. In the following, a backing material and an automobile mat, which is one of its uses, will be described in the process of explaining a rug. The rug of the present invention is, for example, a carpet or mat laid on the floor of a vehicle such as an automobile, train or aircraft, a carpet or mat laid on the floor of a building or hallway, a chair mat for computer operation, a room The present invention can be applied to a wide range of uses such as a floor mat laid at the entrance of a door, a floor mat laid in an elevator or in front of an opening / closing door of an elevator hall, and an entrance mat.

  As shown in FIGS. 1 to 4, the rug 51 of the present invention includes a surface covering material 52 formed by driving pile yarn into a base fabric, and a backing material 53 attached to the back surface of the surface covering material 52. The cover material 52 is driven by a pile yarn 55 in a predetermined volume to form a substantially U shape on a base fabric 54 made of non-woven fabric, paper, cloth, felt, or a composite thereof, and a precoat 56 is applied to prevent it from coming off. It is a thing. In addition, the base fabric 54 in this invention can also take the form which consists only of the base fabric 54 which does not drive the pile thread | yarn 55. FIG.

  In addition, the base fabric 54 constituting the cover material 52 is provided with antibacterial deodorant fibers in which antibacterial deodorant particles, such as titanium, cerium, zinc, copper, etc., coated with a photocatalyst particle surface with a fluorine-based porous layer are attached to the fiber surface Or a conventional antibacterial agent applied or sprayed on the constituent fiber surface of the sheet together with a binder. In this case, the surface covering material 52 comes to have antibacterial properties, efficiently absorbs the bad odor in the room, and decomposes or removes it.

  Further, as shown in FIG. 3, a discharge paper 56 containing conductive fibers and having a static air discharge function is laminated on the base fabric 54 constituting the cover material 52, and the discharge paper 56 and the base fabric 54 are laminated. It is also possible to use a laminate obtained by driving a pile yarn 55a containing conductive fibers into a substantially U shape.

  In this case, when a person comes into contact with the rug 51, the conductive fibers contained in the pile yarn 55a are instantaneously guided to the rug 51 side and discharged in the air by the discharge paper 56 in the rug 51. It becomes like this. A part of static electricity is discharged in the air through the discharge paper 56 and through the conductive fibers included in the pile yarn 55a.

  The conductive fibers contained in the discharge paper 56 and the pile yarn 55a are not particularly limited, and for example, inorganic fibers such as carbon fibers, metal fibers, and conductive ceramic fibers, and synthetic fibers are used as main materials, and the surface of the fibers. Plating fibers plated with metals such as copper, silver, and aluminum, kneaded metals such as copper, silver, and aluminum on the fiber surface, or fibers containing conductive resin in the fiber component are used. be able to.

  The backing material 53 constitutes the greatest feature of the present invention, and comprises a pile knitted or pile woven fabric 61 knitted or woven using a looped pile yarn composed of monofilaments and a support layer 62. As the pile knitted fabric or the pile fabric 61 knitted or woven using the loop-shaped pile yarn composed of monofilament, for example, warp knitting (Russell knitted fabric) knitted using the loop-shaped pile yarn composed of monofilament A knitted fabric obtained by cutting the looped pile yarn, a warp weft knitted fabric (double raschel knitted fabric) having a front surface and a back surface knitted using a looped pile yarn composed of monofilaments, A knitted fabric obtained by cutting a loop pile yarn that connects the front surface and the back surface, a loop pile yarn that joins a front fabric and a back fabric of a double fabric woven using a loop pile yarn composed of monofilaments Loop fabric of a pile fabric woven using a looped pile yarn composed of monofilament Yl yarn can be mentioned cut fabric a.

  The cut end 63a of the looped pile yarn 63 cut from the pile knitted fabric or pile fabric 61 protrudes from the pile knitted fabric or pile fabric 61. For example, as shown in FIG. 5, the 51 rug is laid on the floor (carpet). When a load is applied thereto, the cut end 63a enters the floor surface (carpet) 70 and acts as a locking portion for locking the cut end 63a.

  The loop pile yarn 63 used for the pile knitted fabric or the pile fabric 61 is composed of a thick and hard monofilament. Specifically, polyethylene monofilament, polyester monofilament, polyamide monofilament and the like are desirable, and the fineness thereof is 100 denier or more, preferably 300 denier or more. Further, not only one but also a bundle of a plurality of monofilaments can be used as the loop pile yarn 63.

  Moreover, although the form of the eyes of the pile knitted fabric or the pile fabric 61 is arbitrary, as shown in FIGS. 1-4, for example, net shapes, such as a turtle shell shape, a rhombus shape, and a square shape, are preferable.

  A conductive layer made of a conductive material can also be formed on the surface of the loop pile yarn 63 of the pile knitted or pile fabric 61. For example, the conductive layer can be formed by coating the surface of the loop pile yarn 63 with a mixture of conductive powder such as carbon powder or metal powder mixed with paint.

  The support layer 62 is made of a foamed resin. For example, polyurethane, polyethylene, polypropylene, polyvinyl alcohol, polyvinyl chloride, styrene-butadiene-acrylonitrile copolymer, ethylene-vinyl acetate copolymer, polymethyl methacrylate, Using phenol, urea, etc. as a raw material, these are bubble generating means using a pyrolytic foaming agent, bubble generating means using a volatile solvent, or an inert gas is absorbed into the polymer under high pressure, and at normal pressure Examples thereof include those obtained by foam molding using conventionally known bubble generating means such as bubble generating means for foaming. In the illustrated example, a support layer using foamed polyurethane is employed.

  Although it is arbitrary as a foaming ratio of the foamed resin which comprises the support layer 62, Preferably it is 5-50 times, More preferably, it is 10-30 times. Further, the cell structure of the foamed resin is not particularly limited, but it is preferable that the open cells and the closed cells are mixed in a ratio of 20%: 80% to 80%: 20%. That is, when the ratio of the open cell structure in the foamed resin is large, the sound absorbing property is improved, but it is easy to loosen. It is good to select suitably according to a use or use condition. In the illustrated example, the ratio of open cells to closed cells is 50%: 50%.

  This support layer 62 is attached to the above-described pile knitted fabric or pile fabric 61 via an adhesive. As a result, when a load is applied to the rug, the support layer 62 made of foamed resin that fixes and supports the base of the loop-like pile yarn 63 of the pile knitted fabric or pile fabric 61 is elastically deformed, and the support layer 63 Since the cut end 63a of the loop pile yarn 63 enters the floor surface (carpet) due to the restoring force of the load, the action spreads to the periphery of the portion to which the load is applied, and the direction or magnitude of the load is also increased. The cut end 63a can surely enter the floor (carpet) by the restoring force of the support layer elastically deformed by the load applied to the rug, and the displacement of the rug can be prevented more effectively. The means for attaching the support layer 62 to the pile knitted fabric or the pile fabric 61 is not limited to an adhesive. For example, a layer made of a heat-fusible resin is provided on the surface layer portion of the support layer 62, and this layer is heat-fused. A method such as attaching to the pile knitted fabric or the pile woven fabric 61 can be adopted.

  The support layer 62 can contain at least one of fiber, feathers, nonwoven fabric, woven fabric, and knitted fabric. By including these, the strength of the support layer is enhanced. In addition, since elasticity will fall when the content increases too much, it is good to select suitably according to a use, a use condition, and the kind of floor surface (carpet).

  The support layer 62 may also be a foamed resin layer including a composite sheet integrated with a feather layer sandwiched between two nonwoven fabrics. In this case, the feather layer itself is lightweight, and since the feather layer is integrated with the feather layer sandwiched between two nonwoven fabrics, the strength of the support layer 62 is high, and as a result, the strength is excellent. A lightweight support layer 62 is obtained.

  The support layer 62 can also be a foamed resin layer containing a conductive material. Examples of the conductive material included in the foamed resin layer include at least one of carbon powder, carbon fiber, discharge paper, and carbon nanofiber nonwoven fabric. By adopting a foamed resin layer containing a conductive material, the support layer 62 itself has a function of absorbing static electricity when combined with the above-described cover material 52 having a function of discharging static electricity in the air, and charging the human body. Thus, the effect of absorbing and removing the static electricity more effectively can be achieved. In the illustrated example, a carbon fiber 64 and a carbon nanofiber nonwoven fabric 65 mixed in a foamed resin is used.

  Moreover, in the example shown in FIGS. 1-4, the fiber layer 57 is laminated | stacked on the surface to which the pile knitted fabric or the pile fabric 61 of the support layer 62 is not attached, and the need from this fiber layer 57 side to the pile knitted fabric or the pile fabric 61 side is required. The fiber layer 57 is integrated with the pile knitted fabric or the pile woven fabric 61 through the support layer 62 by ring treatment.

  The fiber layer 57 is a layer having a function of improving the handleability by increasing the strength of the backing material 53 while ensuring air permeability, and creating an appropriate waist in the rug when used as a rug. The fiber layer 57 can take a form including a heat-adhesive fiber. In this case, the fiber layer 57 functions as an adhesive that adheres to the outer covering material 52.

  Preferred examples of the heat-adhesive fibers to be included in the fiber layer 57 include those made of a core-sheath type composite fiber in which a high melting point polymer is disposed as a core component and a low melting point polymer is disposed as a sheath component. In particular, the difference between the melting point of the high melting point polymer and the melting point of the low melting point polymer is preferably 15 ° C. or more, and more preferably 20 ° C. or more. Examples of combinations of high melting point polymer / low melting point polymer include polyester / polyolefin, high melting point polyester / low melting point polyester, polyamide / polyolefin, high melting point polyamide / low melting point polyamide, polypropylene / polyethylene, high melting point polyethylene / low melting point polyethylene, etc. Is mentioned.

  The fiber layer 57 can contain conductive fibers such as carbon fibers and metal fibers. When the fiber layer 57 is combined with the above-described cover material 52 having a function of discharging static electricity in the air, the fiber layer 57 itself has a static electricity. As a result, a static electricity charged on the human body can be absorbed and removed more effectively. In the example shown in the figure, a carbon fiber 64 and a thermothermal adhesive fiber that are included in the constituent fibers of the fiber layer 57 are used.

  Next, the case where the rug is applied to an automobile mat will be described. In addition, the code | symbol used in description of the rug is used as a code | symbol of the mat | matte for motor vehicles as it is. In the embodiment shown in FIG. 5, when the car mat 51 is laid on the car floor (carpet) 70, the cut end 63a of the loop pile yarn 63 in the pile knitted or pile fabric 62 of the backing material 53 is shown in FIG. It protrudes obliquely toward the direction indicated by black coating or marking, that is, the traveling direction of the automobile. For this reason, when a load is applied in the traveling direction (forward) of the vehicle by the driver or the occupant while driving the vehicle, the cut end 63a protrudes obliquely in the same direction. The vehicle mat 51 enters the automobile floor (carpet) 70 to prevent the automobile mat 51 from being displaced. Further, since the cut end 63a does not act as a locking portion in the direction (backward) opposite to the direction (frontward) in the vehicle traveling direction indicated by the white arrow in FIG. The car mat 51 can be easily removed and positioned.

  The form shown in FIG. 6 is a case where the above-mentioned rug is similarly applied to a car mat, and the form shown in FIG. 6 is a backing material when the car mat 51 is laid on a car floor (carpet) 70. The cut end of the loop pile yarn 63 in the pile knitted fabric or pile woven fabric 62 is provided so as to become denser toward the traveling direction of the automobile. The load applied to the automobile mat 51 by the driver or the occupant during driving of the automobile is larger in the front portion of the automobile mat 51 than in the rear portion. For this reason, in the example of FIG. 6, the density of the cut end 63a of the front part of the car mat 51 is increased and the density of the cut end 63b of the rear part is decreased to provide a density gradient, thereby effectively preventing the deviation. The mat was demonstrated.

  The backing material and rug of the present invention are not limited to the examples shown in the drawings. For example, a water repellent, an antibacterial agent, an acaricide, a fungicide and a fiber layer constituting the backing material and the rug are used. By including at least one phthalocyanine compound and imparting performance such as water repellency, antibacterial properties, mite resistance and fungicidal properties to the backing material and rug, it is freely within the scope described in the claims. It can be changed and implemented.
