The latter case is preferable because an appropriate cushioning property can be given to the toilet seat.

As the adsorbent, those having an adsorbing layer having a large number of pores having a vacuum adsorbing force on at least the surface can be used. For example, it is a foamed synthetic resin composition applied to one side of a sheet used as an anti-slip layer of a tile mat, and includes an anti-slip layer having a large number of pores and having a vacuum adsorption force (Japanese Patent No. 2841018). Issue). Such an anti-slip layer is one in which air in the pores is discharged by pressing against the toilet seat, the inside of these pores becomes negative pressure, and an adsorption force is generated, and this toilet force can adsorb the toilet seat sheet to the toilet seat. . The adsorbent can be easily detached from the toilet seat with a little force.

The adsorbent layer may be provided by directly applying the foamed synthetic resin composition to the back surface of the surface fiber layer, or a sheet of nonwoven fabric or the like coated with the foamed synthetic resin composition is opposite to the coated surface. In this case, it can also be produced by bonding to the back surface of the surface fiber layer by using an adhesive or by means such as high frequency bonding.

In the case of the adsorbent, the adhesive (or adhesive) layer is conveniently formed by directly applying an adhesive to the back surface of the surface fiber layer (in the case of a pile fabric or the like) to form an adhesive layer. In the same manner as above, a non-woven fabric sheet coated with a pressure-sensitive adhesive is bonded to the back surface of the surface fiber layer on the surface opposite to the coated surface using an adhesive or by means such as high-frequency bonding. May be. Adhesives (including adhesives) are required to be sticky enough that they do not move or fall off during use, but are easily removed from the toilet seat when changing during washing. Must have adhesive or adhesive strength. As long as these conditions are satisfied, any known pressure-sensitive adhesive (or adhesive) may be used.

The agent layer 4 is laminated. And as a toilet seat sheet in which the adsorbing force and the peeling force of the adsorbent or the adhesive force and the peeling force of the adhesive are balanced, for example, an adsorbent layer or an adhesive as proposed in Patent Document 3 etc. A structure having a number of horizontal grooves or vertical grooves in the layer is also preferably used. Specifically, as shown in FIG. 1, the adhesive layer 4 has a large number of lateral grooves 5 parallel to each other at an equal pitch over the front and rear sides so as to be substantially orthogonal to the virtual axis along the front and rear longitudinal direction. Those put in are preferred. Alternatively, a vertical groove in a direction orthogonal to the horizontal groove 5 may be inserted. In order to form the groove, for example, an adhesive is continuously applied to the surface of the base fabric of the surface fiber layer 3, and at the time of coating, a parallel groove is made with a scraper, and the adhesive is scraped off at the groove portion, followed by heating and drying. Thus, the pressure-sensitive adhesive layer 4 may be formed. This side preferably has a groove width of 0.5 to 4 mm and a distance between grooves of about 10 to 45 mm.

Specifically, the test environment: 20 ° C., 40% RH, a sample table tilted at 45 degrees and a test sample and a control sample (10 × 7 cm) are mounted side by side, and a hot plate (90 ° C.) is placed 15 cm before that. Set in parallel. The surface temperature of both samples is measured with a thermoviewer, and the temperature difference between the two samples is obtained. For the sample, the surface temperature of one bore fabric was measured (n = 5). As a result, the temperature of the surface fiber layer used in the present invention was 0.9 ° C. higher on average than the surface fiber layer for comparison. This result was also clearly confirmed by comparison of surface temperatures by thermography after 120 seconds.

Using the same pile yarn and ground yarn as in Example 1, a cut pile knitted fabric was obtained with a double raschel knitting machine (cut pile length of 4 to 5 mm, basis weight of about 400 g / m 2). This was used as the surface fiber layer of the present invention. On the other hand, as an attachment means, an acrylic resin containing a foaming agent is uniformly applied to one side of a polyester fiber non-woven fabric (thickness: about 3 mm) (thickness: about 0.5 mm), and dried by a tenter. What consists of an adhesion layer and a nonwoven fabric was produced. And the raw material of the toilet seat sheet | seat of this invention was manufactured combining the back surface (non-cut pile surface) of the said surface fiber layer, and the surface of the said nonwoven fabric. Next, the original fabric was die-cut into a toilet seat sheet, and the periphery of the obtained mold was subjected to high-frequency adhesion using a thermoplastic resin as an adhesive to produce the toilet seat sheet of the present invention.
