| 摘要 |
A hot press cushioning material (14a) includes: a first nonwoven fabric (15) forming an inner layer; and second nonwoven fabrics (16a, 16b) placed on both surfaces of the first nonwoven fabric (15) and forming outer layers. Copolymerized para-aramid fibers having a basis weight of 80 to 400 g/m2 are used as a material of the second nonwoven fabrics (16a, 16b). Fibers that are more rigid than the copolymerized para-aramid fibers are used as a material of the first nonwoven fabric (15). Each of the first nonwoven fabric (15) and the second nonwoven fabrics (16a, 16b) has a heat resistant temperature of 270° C. or more. |
