Flashspun fabric

{{Short description|Nonwoven fabrics}}

Flashspun fabric is a nonwoven fabric formed from fine fibrillation of a film by the rapid evaporation of solvent and subsequent bonding during extrusion.

A pressurised solution of, for example, high-density polyethylene (HDPE) or polypropylene in a solvent such as fluoroform is heated, pressurised and pumped through a hole into a chamber. When the solution is allowed to expand rapidly through the hole the solvent evaporates to leave a highly oriented non-woven network of filaments.{{cite book |url= https://books.google.com/books?id=j4Iep0AKhHcC&pg=PA87|title=The Illustrated Dictionary of Textile|first=Larry |last=Operath|publisher=Lotus Press|year=2007|ISBN=978-81-89093-62-4|page=87}}{{cite book |url= https://books.google.com/books?id=0g9QjxsbqmUC&pg=PA268|title=Concise Encyclopedia of Plastics|author1=D.V.
