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.
Tyvek is a nonwoven product consisting of spun bond olefin fiber.It was first discovered in 1955 by a researcher for the DuPont textile company working in an experimental lab, who noticed a type of white fluff coming out of a pipe. [2]
Multiple colored swatches of non-woven fabric. Nonwoven fabric or non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres (continuous long), bonded together by chemical, mechanical, heat or solvent treatment.

The pouches are made of a material that is permeable to water vapor but not to the solution within, such as flashspun high-density polyethylene fibers ("Tyvek"). To minimize leaks in the event a pouch is damaged, the solution is thickened with an agent such as hydroxyethylcellulose, xanthan gum, or alginate, to produce a hydrocolloid.

The principal uses of cellulose nitrate is for the production of lacquers and coatings, explosives, and celluloid. [6]In terms of lacquers and coatings, nitrocellulose dissolves readily in organic solvents, which upon evaporation leave a colorless, transparent, flexible film. [4]
