  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a water absorbing tape for a sink according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a water absorbing tape for a sink according to the present invention, FIG. 2 is a plan view showing the back surface of the water absorbing tape for the sink, and FIG. 3 is a position of the water absorbing tape for the sink in FIG. FIG. 4 is a cross-sectional view taken along the line IV-IV in FIG. 2 of the water absorption tape for the sink.

  A water absorbing tape 1 for a sink according to the present invention has a water absorbing layer 2, and an adhesive layer 3 is provided on one surface of the water absorbing layer 2.

  The water absorption layer 2 is formed of a nonwoven fabric. The nonwoven fabric is processed by relatively thin-walled fibers formed by entanglement of fibers in which a first thermoplastic fiber such as polyester is mixed with a second thermoplastic fiber that melts at a lower melting point than the thermoplastic fiber. A sheet-like web is formed, the sheet webs are overlapped to form a relatively thick lap web, the lap web is made into a felt shape by needle punching, and one surface of the felt web is raised by needle punching. The nonwoven fabric formed in this way has good water absorption and moderate flexibility (flexibility).

  Next, the adhesive layer 3 having adhesiveness and shape retention is applied and formed on one surface (back surface) of the water absorbing layer 2 (nonwoven fabric). For the adhesive layer 3, a synthetic resin material is used in which a filler is blended with an emulsion of a tacky acrylate copolymer and a methyl methacrylate butadiene copolymer that is well compatible with thermoplastic fibers.

  The adhesive layer 3 is formed by the following process. A stirring chamber communicating with an air source is provided in the middle of the delivery path for sending out the solution of the synthetic resin material described above by a pump, and the solution supplied to the stirring chamber is stirred by blowing air into the stirring chamber. After foaming the solution, this foamed solution is applied to the back surface of the nonwoven fabric constituting the water absorbing layer 2 from the outlet of the delivery path, and the applied foamed solution is leveled with a doctor blade, and then dried in a drying room at about 120 ° C. After drying for 1 to 2 minutes, after taking out from the drying chamber and cooling, the foamed solution is cured in a state having adhesiveness, and an adhesive layer 3 of adhesive resin having a plurality of microbubbles is formed. It is formed. The adhesive layer 3 has a thickness of about 0.5 mm. A part of the solution applied to the back surface of the nonwoven fabric penetrates into the nonwoven fabric.

  The second thermoplastic fibers of the nonwoven fabric are melted by drying when the adhesive layer 3 is formed, and the first thermoplastic fibers of the nonwoven fabric can be bonded to each other by the second thermoplastic fibers. The thermoplastic fiber of 2 and the acrylic acid ester copolymer and methyl methacrylate butadiene copolymer in the solution react chemically to form a cross-linking bond between molecules, thereby increasing the bonding strength of the adhesive layer 3 to the nonwoven fabric. In addition, the shape retention of the nonwoven fabric can be improved, and wrinkles due to washing can be prevented.

  Furthermore, the above-mentioned drying causes a chemical reaction between the acrylic ester copolymer and the methyl methacrylate butadiene copolymer in the foamy solution, resulting in cross-linking between molecules, and all the foam in the solution is microscopic. It becomes a bubble. The shape retention of the adhesive layer 3 can be improved by the cross-linking of the acrylic ester copolymer and the methyl methacrylate butadiene copolymer in this solution, and the shape retention of the nonwoven fabric is further improved by the shape retention. In addition, wrinkles caused by washing can be prevented even better. Moreover, since microbubbles are also generated on the surface of the adhesive layer 3, when the adhesive layer 3 is pressed against a flat floor surface or the like, each of the plurality of microbubbles exposed on the surface discharges the internal air and performs a vacuum adsorption action. None, the vacuum adsorption action and the adhesiveness enhance the adhesiveness of the adhesive layer 3.

  Next, the water absorbing tape 1 is formed by cutting the water absorbing layer 2 on which the adhesive layer 3 is formed as described above into a tape shape. The dimensions of the water absorbing tape 1 are, for example, about 100 mm wide and 900 mm long.

  The adhesive layer 3 of the water-absorbing tape 1 is formed with a fold line 3a having a convex side of the water-absorbing layer 2 along the tape longitudinal direction at the central position in the tape width direction, and a plurality of grooves 3b intersecting with the fold line 3a. They are arranged side by side at intervals of about 15 mm in the longitudinal direction. The layer thickness of the adhesive layer 3 is the same in the fold 3a and the portion other than the fold 3a, and the opposite side of the crease 3a to the water absorption layer 2 has a depth similar to the height of the protrusion on the water absorption layer 2 side. A recess (groove) is formed. The width of the groove 3b is about 2 mm, and is inclined from the end of the groove toward the center, and the layer thickness is the smallest at the center.

  The groove 3b is formed by bringing a substantially U-shaped heating portion of a high-frequency heater into contact with the surface of the adhesive layer 3, and heating and pressing the adhesive layer 3 while partially melting the heating portion. The crease 3a is formed by bringing a substantially V-shaped heating part into contact with the surface of the adhesive layer 3, and heating and pressing the adhesive layer 3 at a temperature at which the adhesive layer 3 is not melted by the heating part.

  Next, the use of the water absorbing tape for a sink according to the present invention will be described.

A faucet 5 is provided on the back side of the water tank 4b, and the edge 4c on the near side constitutes a part of the top plate 4a. When the water-absorbing tape 1 is bent in the tape width direction with the adhesive layer 3 inside, the adhesive layer 3 is bent at the concave portion on the opposite side of the water-absorbing layer 2 of the fold 3a along the longitudinal direction of the tape. Since the convex portion of the first bite bites into the water absorption layer 2 and the surface of the water absorption layer 2 protrudes along the crease 3a, the upper surface 4c1 of the edge portion 4c on the near side of the sink 4 passes through the crease 3a of the adhesive layer 3 and the upper surface. The adhesive layer 3 is attached to the upper surface 4c1 and the outer surface 4c2 of the edge portion 4c on the near side of the sink 4 by positioning near the corner formed by the outer surface 4c2 continuous with the outer end portion of 4c1.

  FIG. 6 shows a case where the water return ridge is not provided on the upper surface 4c1 of the edge 4c, and FIG. 7 shows a case where the water return ridge is provided on the upper surface 4c1 of the edge 4c. In any case, the adhesive layer 3 of the flexible water-absorbing tape 1 is bent along the surface of the upper surface 4c1 and the outer surface 4c2 of the edge 4c, bent at the fold 3a, and the surface protruded along the fold 3a. It can be confirmed that the tape 1 is well adhered along the corner shape of the upper surface 4c1 and the outer surface 4c2 of the edge 4c.
