Abstract:
A creasing method includes: a gripping and rotating step of bunching and gripping a continuously drawn long fiber non-woven fabric and rotating the gripped part so that the long fiber non-woven fabric is twisted and a first folding line is formed; a heating step of heating the twisted long fiber non-woven fabric to fix the first folding line; and a widening step of releasing the long fiber non-woven fabric having the first folding line formed thereon.
