A medical dressing material having a chitosan fabric sponge structure according to the present disclosure has a structure in which chitosan fibers derived from a chitosan fabric are located on a porous structure formed using freeze-drying. Therefore, the medical dressing material has an excellent hemostatic effect and exudate-absorbing ability while exhibiting a strong tensile force, is convenient to use, and is capable of being molded into various forms so as to be widely used for wounds by an edged thing, scalds, pressure ulcers, diabetes-related foot disorders, or various surgical areas in various body tissue parts such as the spine, brain, eye, ear, nose, and cervix.

A highly permeable superabsorbent is prepared by a process comprising

polymerizing an aqueous monomer solution comprising
a) at least one ethylenically unsaturated monomer which bears acid groups and is optionally at least partly in salt form,
b) at least one crosslinker,
c) at least one initiator,
d) optionally one or more ethylenically unsaturated monomers copolymerizable with the monomers mentioned under a), and
e) optionally one or more water-soluble polymers;
drying the resulting polymer,
optionally grinding the dried polymer and sieving the ground polymer,
optionally surface postcrosslinking the dried and optionally ground and sieved polymer,
wherein, after drying, grinding or sieving, and, if surface postcrosslinking is conducted, during or after this surface postcrosslinking, x-ray-amorphous aluminum hydroxide powder is added.

A film having low pressure values is provided. The film may have from about 20 wt. % to about 75 wt. % of a polyolefin component, from about 5 wt. % to about 35 wt. % of an elastomeric resin, and from about 20 wt. % to about 45 wt. % of a particle component. The film may have a basis weight of from about 5 gsm to about 25 gsm. The film may have a predicted sound pressure level over the frequency octave range of 2000 Hz-6300 Hz of less than about 43 dB.
