The mat material, the rubber sheet 4 and the elastomer film 6 are simultaneously heated to a high temperature to vulcanize the rubber sheet 4 and the elastomer film 6.
The labeled dust removal mat of the present invention is manufactured by vulcanizing and fixing them together.

(Effects of the Invention) In the labeled dust removal mat of the present invention, the label is completely covered with an elastomer film that is integrally fixed to the rubber sheet of the mat, so that the dust removal mat with a label can be used on the floor while the mat is in use. The label will not separate from the mat even if it is subjected to friction with the mat or is subjected to repeated cleaning treatments, and can fully perform the function of displaying the contents written on the label throughout the life of the mat. It has excellent functions and effects.

In addition, the manufacturing method of the labeled dust removal mat of the present invention uses the equipment conventionally used for manufacturing dust removal mats as is, and adds a few simple operations such as adding a label and an elastomer film. By simply doing this, it is possible to easily produce a dust removal mat with a label that exhibits the excellent functions and effects as described above without requiring any other special work steps.

(Preferred Embodiment of the Invention) The base fabric used in the present invention includes a synthetic fiber woven fabric,
In addition to base fabrics such as knitted fabrics, gauze, and non-woven fabrics, any base fabrics such as plastic nets and metal nets may be used. on the other hand,
Pile fibers for tufting include natural fibers such as cotton, wool, and hemp fibers, regenerated fibers such as viscose silk, polynosic fiber, copper ammonium silk, and cellulose acetate fibers, polyester fibers, and polyamide fibers. Synthetic fibers such as acrylic fibers, polyimide fibers, polyolefin fibers, polyvinyl alcohol mm, polyvinyl chloride m fibers, polyvinylidene chloride fibers, or composite fibers thereof, and mixed m fibers consisting of a combination of two or more of these fibers. is used. These ams include spun yarn 1 twisted yarn, core spun yarn,
It can be used as a pile yarn in any form such as multifilament, perlock spun yarn, or interlace yarn.

The tactified mat used in the present invention is obtained by tactifying the pile yarns on the base fabric described above, and optionally coating the back side with synthetic latex to form a thin backing layer. It can be used as a mat in a rolled form, and can also be used as a mat by trimming the ends of the pile. Mats of the Gonagi type are suitable as dust removal mats.

In the pile yarn for tufting, the fineness of the single fibers is desirably in the range of 0.5 to 300 deniers, particularly 5 to 50 deniers, from the viewpoint of dust adsorption and dust retention. In this regard, it is preferable that the pile yarn has a fineness of 10 to 5,000 deniers, particularly 100 to 2,000 deniers, and the stitch density of the pile yarn is 3 to 300 pieces per unit area inch.

In particular, it is desirable that the number be in the range of 20 to 70.

The pile yarn for tufting may be either non-spoolable or spoolable.For example, a nylon filament with latent spooling properties may be used, and when the matte backing is cured, It is also possible to perform a winding process on the tufted pile yarn by using the heating in .

The pile length of the mat can be varied, but it is generally in the range of 3 to 30 mm, particularly 6 to 12 m + w.
If it is shorter than the above range, it is unsatisfactory in terms of dust adsorption and dust retention, and if it exceeds the above range, the cleaning workability during regeneration cleaning will be poor. descend.

In order to prevent the pile threads from falling off during handling of the tufted mat and to improve the adhesion between the rubber sheet and the tactified mat, a thin backing layer is coated with synthetic rubber latex on the back side of the tufted mat in advance. As the synthetic rubber latex that is preferably formed, it is preferable to use various rubber latexes, especially latexes of the same type as the rubber sheet described below.Such latexes have a solid content in the range of 10 to 70% by weight. Certain latexes are preferably used, the coating weight being generally between 10 and 2000 g/m2. Especially ioo to 500g/112
It is desirable that it be within the range of .

As a rubber composition for forming a rubber sheet, C. Example Jf, ethylene-propylene rubber, ethylene-propylene-nonconjugated diene rubber, polybutadiene, polyisoprene, polyisobutylene-polybutyl rubber, styrene-butadiene rubber, nitrile-butadiene rubber, acrylic Any rubber composition such as rubber, fluororesin rubber, polyurethane rubber, vinyl chloride resin soft rubber composition, etc. can be used.

These rubbers may be compounded with compounding agents 1 which are known per se, such as vulcanizing agents, vulcanization aids, anti-aging agents, reinforcing agents, fillers, pigments and the like.

Although the thickness of the unvulcanized rubber sheet can be varied, the thickness is determined so as to at least prevent the backstitch from popping out and provide a good fit to the floor surface. Generally speaking, its thickness is between 0.3 and 7 layers, especially 0.5
It is preferable that the distance be within a range of 5 m to 5 m.

As a rubber component of a rubber composition for forming an elastomer film, it itself has transparency or translucency after vulcanization, and when vulcanized simultaneously with a rubber composition for a rubber sheet, it can be vulcanized with a rubber sheet. As long as it can be fixed, does not discolor or break when the mat is washed, heated, etc., and has heat resistance, cold resistance, oil resistance, water resistance, alkali resistance, abrasion resistance, etc. For example, in addition to those exemplified as rubber components for rubber sheets, chloroprene rubber, epichlorohydrin rubber, thiol rubber, silicone rubber,
Hypalon etc. can be used. Particularly preferably, a rubber component that is the same as or of the same type as the rubber component used for the rubber sheet is used. The rubber composition for forming the elastomer film cannot contain fillers such as carbon black that completely lose the transparency of the vulcanized product, but the transparency of the film after vulcanization Ingredients known per se can be added to the extent that translucency is maintained. In particular, the use of silicon oxide as a filler can increase strength without losing transparency. The thickness of the elastomer film can be appropriately selected in consideration of its transparency and durability. Generally speaking, it is preferably between 0.01 and 3II11, particularly between 0.05 and 2 mm.

Vulcanization of the rubber sheet and elastomer film is performed using pressure on the matte surface of ■ to 20KgIc layer 2 (gauge).
Preferably under a press pressure of 2 to 20 Kg/cm2 (gauge), at 100 to 200°C, preferably at 130°C.
At a temperature of 160°C to 160°C for 5 to 60 minutes, preferably 1
It is carried out for 0 to 30 minutes.

Labels are commonly used, such as paper, resin film, cloth, etc., with the quality, name, purpose, manufacturer's name, license number 1, and other necessary information printed on one side of paper, resin film, cloth, etc. This is what is displayed.

#Adhesive may be applied to the opposite side of the label.

In addition to the above-mentioned method of sequentially overlapping each material and then vulcanizing and fixing the materials, the manufacturing method of the present invention is to first place a label on a rubber sheet or temporarily adhere it with adhesive, and then The elastomer film is placed on top of the rubber sheet with a small amount of adhesive temporarily attached to the rubber sheet at several points so as to completely cover the label, and then placed on the lower mold of the press, and then vulcanized in the same manner as above. A method of manufacturing a dust removal mat with a label by fixing it can also be used.

Further, the surface of the lower press die may be processed to give the rubber sheet a double-sided pattern, but it is preferable that the portion facing the label portion be a smooth surface.

In the present invention, the matte pile yarn can be made into a cut pile by trimming the ends of the looped pile prior to the backing operation, or the ends of the looped pile can be cut off after the backing operation is completed. You can also make a cut pile by aligning them. In addition, the looped pile yarn can be used as a backing mat without cutting the cut ends.

The labeled dust removal mat of the present invention is useful as a dust removal mat for removing dust or dirt adhering to the soles of shoes, etc. by laying it on the floor of entrances and exits such as entrances. Although the backing mat of the present invention can be used for such dust removal mat applications without special treatment, it is generally necessary to apply a dust absorbent, especially a dust-retaining oil, to the pile threads of the mat. It is desirable to keep it.

The oil agent used in this type of mat according to the present invention has a dust-absorbing oil composition that is mainly composed of mineral oil and contains an amphoteric surfactant, a cationic surfactant, an antifungal agent, a bactericidal agent, etc. A fragrance, an antioxidant, etc. are added as necessary.
