[0090] Hereinafter, the present invention will be described more specifically based on examples, but the present invention is not limited to these examples.
[0091] The physical property values and the like in Examples and Comparative Examples were measured by the following methods.
[0092] (1) Item payment [g / m 2 ]
[0093] From the (mixed fiber) spunbonded nonwoven fabric, take 6 test pieces of 200 mm (MD) x 50 mm (CD). Here, the selected positions are arbitrary 3 positions on both MD and CD (total 6 positions). Next, the mass (g) of each of the taken test pieces was measured using an electronic balance (manufactured by Kenseiko Co., Ltd.). The average value of the mass of each test piece was calculated|required. Converted from the obtained average value to every 1m 2 The mass (g) of each nonwoven fabric sample is rounded off to the second place after the decimal point [g / m 2 ].

[0095] From the (mixed fiber) spunbond nonwoven fabric, t...
manufacture example 1
[0139] Diphenylmethane diisocyanate (hereinafter referred to as MDI) was put into a tank under a nitrogen atmosphere, and the temperature was adjusted to 45° C. while stirring so as not to mix air bubbles.
[0140] Under a nitrogen atmosphere, 628.6 parts by weight of polyester polyol (manufactured by Mitsui Takeda Chemical Co., Ltd., trade name: Takelack U2024), 2.21 parts by weight of Irganox (Irganox) with a number average molecular weight of 2000 1010 and 77.5 parts by weight of 1,4-butanediol were put into the B tank, and it adjusted to 95 degreeC, stirring. This mixture is referred to as polyol solution 1.
[0141] The amount of hard segments calculated from these reaction raw materials was 37.1% by weight. Next, MDI and polyol solution 1 were quantitatively transported to a high-speed mixer (SM40) adjusted to 120°C at flow rates of 17.6 kg / h and 42.4 kg / h through the infusion line through a gear pump and a flow meter. , after stirring and mixing at 2000rpm for 2 minut...
