Abstract (en)

[origin: EP4011238A1] A hair holder (1) includes a tubular body (2) constructed in such a manner that a hair bundle (H) is insertable from an opening (1a) at one end toward an opening (1b) at the other end. The hair holder (1) has a longitudinal direction (X) and a width direction (Y). The hair holder (1) is constructed in such a manner that the hair holder can be rolled up along the longitudinal direction (X). The hair holder (1) includes a first sheet (21) to be located on an inner side in the rolled-up state, and a second sheet (22) to be located on an outer side. One or both of the two sheets (21, 22) satisfies at least one of condition (1) or (2) below: (1) the sheet includes a polyester-based nonwoven fabric, and the sheet's storage modulus E' in dynamic viscoelasticity measured at 100°C at a frequency of 1 Hz is 50 MPa or greater; or (2) the sheet includes a polyester-based nonwoven fabric, and the sheet's storage modulus E' in dynamic viscoelasticity measured at 150°C at a frequency of 1 Hz is 19.2 MPa or greater.
