摘要： A method of charging fibrous webs with nonaqueous polar liquids. A web (20) that contains nonconductive fibers is wetted with a nonaqueous polar liquid (14). The web (20) is then substantially dried (22) to provide a fibrous electret web. The fibrous electret web can be used as a filter in a filtration face mask (40) that is adapted to cover the nose and mouth of the wearer. The present method has the advantage over known charging methods in that the nonaqueous liquid requires less energy for drying than is required for aqueous liquids. Additionally, many filter webs can be directly wetted with nonaqueous liquids, which cannot be easily wetted with aqueous liquids.

摘要： The present disclosure describes a surfactant treatment for a polyolefinic nonwoven fabric used to wrap items to be sterilized. The surfactant treatment consists essentially of carbon, hydrogen and oxygen atoms. The surfactant treated sterile wrap has a BFE after electret treatment and after sterilization of at least 97 percent. This treatment should produce fewer wet packs than the same fabric after electret treatment and after sterilization but without such surfactant treatment.

摘要： Des biséthers de dérivés oxydés du thiodiglycol de formule générale (I): R1-O-(C2H4O)x-(C2H4-SOz-C2H4-O)w-(C2H4-O)y-R2 où R1 et R2 = groupes alkyle ou alcényle à chaîne droite ou ramifiés avec 6 à 30 atomes de carbone, ou hydrogèn, x + y = 0 à 20, w = 1 à 5, z = 1 ou 2, R1 et R2 pouvant être identiques ou différents, peuvent être préparés par réaction de thiodiglycol avec des alcools gras éventuellement éthoxylés, suivie d'une oxydation. La condensation se produit, de façon appropriée, en présence de composés acides et l'oxydation s'effectue en particulier avec du peroxyde d'hydrogène. Les composés ont une utilisation comme adoucissants des textiles.
