Abstract
A method of forming polymeric fibers, first forming a mixture containing water, the polymer, and an organic liquid capable of dissolving or swelling the polymer, and secondly by suddenly vaporizing the mixture by passing it from a high pressure zone to a pressure zone lower, whereby the organic liquid evaporates and the polymer precipitates in the form of fibers, characterized in that the water mixes with the polymer and the organic liquid in such a way that the water disperses as droplets in a continuous phase that It comprises the polymer and the organic liquid.
