あつた。 The mainstream tape base materials are those made by laminating non-woven fabric such as rayon non-woven fabric and paper material, and those made by laminating plastic on both sides of non-woven fabric, but the laminated type is expensive, and the laminated type is expensive. In addition to the inconvenience of easily damaging the skin, the flexibility of both nonwoven fabrics is reduced, and the tear strength is significantly reduced because it depends on the laminated paper and plastic layers.
It had the disadvantage that it would break if unnecessary force was applied.

For example, a fiber made of a high melting point material and a fiber made of a low melting point material may be twisted together and twisted together, or both fibers may be mixed and then twisted together, or the surface of the fiber made of a high melting point material may be partially or completely covered with a low melting point material. The high-melting point material and the low-melting point material are essentially integrated and have approximately the same length. It is used in the form of staples (short fibers) or filaments (long fibers), and the basis weight is determined by a conventional method.
It is processed into a nonwoven fabric of 10 to 300 g/ m2 , and the ratio of high melting point material to low melting point material per unit volume is 1:9 to 9:1, preferably 3:7 to 7:
The ratio is said to be 3.

One side is a heating roll (may be a textured roll)
Then, the low melting point materials at least in the surface portions may be partially or entirely fused together between a pair of rolls, one of which is a non-heated roll, or both of which are heated rolls. Heat treatment further improves the interlaminar strength and tear strength of the nonwoven fabric.

Alternatively, the fastener tape C may be provided with a release layer 6 on the back surface if necessary. The fastener tape C is cut to a predetermined size in the width direction, and
100-300℃ x 2-200 on the front or back of the diaper
Thermal bonding is carried out under heating and pressing conditions of Kg/cm 2 ×0.1 to 5 seconds.
