A mask assembly includes a liner and one or more patches coupled to the liner. The liner includes a front sector that includes one or more rim portions and a lower portion. The rim portions define one or more eye openings, and the lower portion at least partially define a head opening. The liner is at least partially fabricated from a first fabric. The patches include one or more edge portions that are coupled to the rim portions such that the patches extend at least partially across the eye openings. The patches are fabricated from a second fabric different from the first fabric.

The present disclosure relates to the technical field of medicines, and in particular, to a composite scaffold material, a preparation method therefor and use thereof. The present disclosure provides a composite scaffold material, including a charged fiber framework material. The fiber framework material is coated with positively charged biocompatible materials and negatively charged biocompatible materials alternately, by means of electrostatic attraction. The composite scaffold material of the present disclosure overcomes the defects of traditional scaffold materials, such as poor hydrophilicity, biocompatibility, histiocyte adhesion ability, and biological induction activity. The composite scaffold material has better applicability when used for tissue adhesion, closure, leaking stoppage, hemostasis, isolation, repair, and adhesion prevention, and can also be used for preparing a drug carrier (e.g., sustained release carrier) and a tissue engineering scaffold material. Therefore the composite scaffold material has a wide range of industrial uses.

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.
