The backing of the present invention includes, for example, carpets and mats laid on the floor of vehicles such as automobiles, trains and aircraft, carpets and mats laid on the floor of buildings and corridors, chair mats for computer operations, and rooms. It is suitably used for floor mats laid at the entrances and exits, floor mats laid in elevators and in front of elevator doors, entrance mats, and the like.

1 to 3, the monofilament bundle 21 is tufted on the resin backing 17a at predetermined intervals, and the cut end 21a of the cut loop of the monofilament bundle 21 protrudes from one side of the resin backing 17a. A mat 30 is shown in which a backing 17 is used and a fiber substrate 10 or 20 is provided on the backing 17 .

  In the example shown in FIGS. 1 to 3, the resin backing 17 a has an open cell structure, and a large number of misalignment preventing projections 19 for preventing misalignment are formed on the back side thereof. Examples of the resin constituting the resin backing 17a include styrene-butanediene-styrene copolymers, acrylonitrile-butadiene copolymers, polymers such as urethane resins, styrene-butanediene rubber, acrylonitrile-butanediene rubber, Examples thereof include rubber polymers such as butanediene rubber, natural rubber and isoprene rubber, or a mixture of a plurality of these. Moreover, you may add a filler and a thickener to the said resin as needed.

Examples of the thickener include polyacrylic acid soda, carboxymethylcellulose, polyvinyl alcohol, casein, and fermented polysaccharides, with low molecular weight sodium polyacrylate being preferred.

  Moreover, the resin backing 17a shown to FIGS. 1-3 has many through-holes 18 penetrated in the front and back. Air enters and exits the fiber base 10 or 20 side of the mat 30 through the large number of through holes 18, and as a result, excellent sound absorption is exhibited. Note that the number, size, shape, interval, and arrangement of the through holes 18 are arbitrary, and may be appropriately changed according to the required sound absorption.

  The monofilament bundle 21 is tufted for each of the many through holes 18 of the resin backing 17a. By tufting the monofilament bundle 21 for each of a large number of through holes 18 of the resin backing 17a, a loop of a large number of monofilament bundles 21 is formed on both surfaces of the resin backing 17a and formed on one side of the resin backing 17. By cutting the pile, as shown in FIGS. 1 to 3, the cut end 21a protrudes to one side of the resin backing 17a. For this reason, for example, even if a cut pile carpet is laid on the automobile floor, the cut end 21a of the monofilament bundle 21 protruding to one side of the resin backing 17a catches the automobile floor and ensures the displacement of the mat. Will come to prevent. Further, by adopting such a configuration, when sound passes through the numerous through holes 18 of the resin backing 17a, the monofilament bundle 21 is repeatedly collided with the sound absorption effect by the through holes 18. More effective sound absorption.

  The length of the cut end 21a of the monofilament bundle 21 protruding to the one surface side of the resin backing 17a is arbitrary, but may be appropriately changed according to the required size of the shift prevention function.

For this reason, in the backing 17 shown in FIGS. 1 to 3, the cut end 21 a of the monofilament bundle 21 and the protrusion 19 for preventing displacement catch the automobile floor surface, and prevent the mat from being displaced more reliably. It has become. For this reason, there is an advantage that the mat can be surely prevented from being displaced regardless of whether the cut pile carpet is laid on the automobile floor or the felt is laid.

  As the monofilament constituting the monofilament bundle 21 tufted to the resin backing 17a, nylon monofilament and polyester monofilament are preferable, and those bundled to a thickness of 200 to 400 denier are preferable.

  Moreover, as shown in FIGS. 1-3, it is desirable to provide a retaining layer on the other surface side of the resin backing 17a in order to prevent the cut monofilament bundle 21 from falling off the resin backing 17a. Examples of the retaining layer of the monofilament bundle 21 include those made of a spider web-like porous adhesive sheet. As this permeable adhesive sheet, there can be used those formed into a thin film by heat and / or pressure during bonding, and those obtained by kneading and forming a foaming agent in an adhesive resin such as a hot melt resin. . In the example shown in FIG. 3, the permeable adhesive sheet 16b is placed on the other surface side of the resin backing 17a and hot-pressed, so that the permeable adhesive sheet 16b becomes a thin film (film) shape and the monofilament bundle 21 It comes to stop the omission. Further, the porous adhesive sheet 16b in the form of a thin film (film) serves to simultaneously solidify the root of the monofilament bundle 21, so that the cut protruding on one side of the resin backing 17 of the monofilament bundle 21 is thereby performed. The waist becomes stronger at the end 21a, and the effect of preventing the mat from shifting is further enhanced.
