Abstract:
A hydrated, nonwoven nanocellulose sheet and method for manufacturing the nanocellulose sheet are disclosed. The method of manufacture comprises the steps of diluting a purified nanocellulose slurry to form a colloidal nanocellulose suspension, dispersing pure nanocellulose crystals into the nanocellulose suspension in a nanocellulose crystal to total nanocellulose ratio less than 50% weight per weight (w/w), placing the suspension over a filter sheet in a dispensing device, and forming the hydrated, nonwoven nanocellulose sheet by filtering with a pressure difference across the filter sheet, via a high pressure or vacuum filtration process. The hydrated, nonwoven nanocellulose sheet thus manufactured has high conformability, drape-ability, good adhesion to the skin, and a high rate of evaporation, making it ideal for dermatological treatments.
