Heat-resisting cushion material and method for producing the same |
摘要 |
The base layer of the cushion material is comprised of a ground body of meta-aromatic polyamide fibers and a bonding layer of substantially non-drawn meta-aromatic polyamide fibers integrated by needling. The airtight layer over the base layer comprises a non-woven fabric sheet of meta-aromatic polyamide fibers. The non-woven fabric sheet is integrated to the base layer under pressure by applying temperatures at or above the glass transition temperatures but at or below the decomposition temperatures of the constitutent fibers of the bonding layer. <IMAGE> |
