Problems solved by technology

[0012] Therefore, the present inventors considered using ultrasonic cutting and welding instead of punching. However, for example, acrylic fibers are difficult to melt, and acrylic fibers and other raw materials (polyester, etc.) have different melting points.

Embodiment 1

[0048] Such as figure 1 As shown, the toilet seat sheet of the present embodiment 1 is installed on the upper surface of the toilet seat 11 of the Western-style toilet 1 so as to be detachable. This toilet seat sheet 2 is comprised by a pair of sheet|seat formed in the substantially crescent shape which is long in front and back and symmetrical about left and right, and substantially follows the planar shape of a toilet seat.

[0049] Such as image 3 As shown, the toilet seat sheet 2 is composed of 4 layers when in use. According to the order from top to bottom, there are knitting layer, core layer 23 , buffer layer 24 and adhesive layer 25 which are composed of surface layer yarn 21 and inner layer yarn 22 . At the time of sale, since the adhesive layer 25 is covered with the release sheet 26, it becomes 5 layers.

[0050] The surface layer yarn 21 is 100% acrylic yarn with a height of about 5-10 mm. The inner layer yarn 22 is composed of 2-5 reeded 100% polyester yarns....

Embodiment 2

[0066] Figure 5 and Figure 6 Be embodiment 2 of the present invention.

[0067] Such as Figure 5 As shown, this toilet seat sheet 2A is composed of four layers in use. The order from top to bottom is the surface yarn layer 21A, the core layer 23A, the buffer layer 24A, and the adhesive layer 25A. At the time of sale, since the adhesive layer 25A is covered with the release sheet 26A, it becomes five layers.

[0068] In contrast to Example 1, the inner layer yarn 22 is absent. In addition, unlike Example 1, the core layer 23A and the cushion layer 24A are tufted by the acrylic yarn constituting the surface layer yarn layer 21A.

[0069] The materials and basis weights of the surface layer yarn layer 21A, the core material layer 23A, the cushion layer 24A, the adhesive layer 25A, and the release sheet 26A are the same as in Example 1.

[0070] Hereinafter, the method of forming the edge part of 2 A of toilet seat sheets is demonstrated.

[0071] First, the core layer 2...

Abstract

The present invention provides a toilet seat cushion with a propylene yarn surface and the edge contour of the toilet cushion is not damaged under the circumstance of without particular edge process by ultrasonic cutting welding. The toilet seat cushion is mounted on the upper surface of a western toilet seat or a cleaning and heating device, is free for dismounting and is a pair of crescent-shaped pieces. Each piece (2) at least includes a knitted layer composed of a surface layer of yarn (21) and an inner layer of yarn (22), a core member layer (23), a buffer layer (24), and an adhesive layer (25). The surface layer of yarn (21) is propylene yarn. The inner layer of yarn (22) is polyester yarn. The core member layer (23) is any of polyester spunbonded nonwoven fabric, polyester canvas, and polyester hot melt pieces. The buffer layer (24) is nonwoven fabric.

Description

technical field [0001] The present invention relates to a toilet seat sheet which is attached to the upper surface of a toilet seat of a Western-style toilet so as to be detachably used, and its manufacturing method. Background technique [0002] Not only based on hygienic considerations, but also from the viewpoint of improving sitting comfort and heat retention, toilet seat covers made of fabrics (fabric, knitted fabrics, non-woven fabrics) are often installed and sold as such toilet seat covers With various products. [0003] Generally, the upper surface shape of a toilet seat is almost always an O-shape or a U-shape. Furthermore, it is also popular to install an inverted U-shaped washing and heating device. As a toilet seat cover which can be attached to any toilet seat of these shapes, the toilet seat cover which consists of a pair of sheet|seat formed in the substantially symmetrical crescent shape formed in front-back long and left-right symmetrical and substantiall...
