Abstract: A fine fiber can be made having a structure with an axial core and a coating layer. The fiber can have a polymer core and one or two layers surrounding the core. The fine fiber can be made from a polymer material and a resinous aldehyde (e.g., melamine-aldehyde) composition such that the general structure of the fiber has a polymer core surrounded by at least a layer of the resinous aldehyde composition.

Abstract: A process for separating the components of a gas mixture, including a sterilant gas and a diluent gas is disclosed. The gas mixture is fed to a membrane separation unit within which a perm-selective membrane is located which allows migration of diluent gas and sterilant gas at different rates. Both sterilant-rich and diluent-rich gas streams are withdrawn from the membrane separation unit and optionally recovered or further processed to a less hazardous compound. The process may be utilized to separate and treat the constituents of the exhaust gases from a chemical sterilization process of which the common components are olefin oxides such as ethylene oxide as a sterilant and chlorofluorocarbons (freon) such as dichlorodifluoromethane (CFC-1) as a diluent.
