摘要： A process for the preparation of plexifilamentary film-fibril strands of polymer. The process includes the steps of generating a spin fluid containing (a) 5 to 30 wt. % containing one or more polymer types, (b) a primary spin agent selected from the group consisting of dichloromethane, cis-1,2-dichloroethylene and trans-1,2-dichloroethylene, and (c) a co-spin agent comprising 1H,6H-perfluorohexane or 1H-perfluorohexane or 1H-perfluoroheptane. The spin fluid is flash-spun at a pressure that is greater than the autogenous pressure of the spin fluid into a region of lower pressure to form plexifilamentary film-fibril strands of the polymer. The co-spin agent is present in the spin fluid in an amount sufficient to form an azeotrope-like composition with the primary spin agent in the presence of the one or more polymer types. The polymer may be selected from the group consisting of high density polyethylene, polypropylene, polybutene-1, polymethylpentene, polyvinylidene fluoride, poly (ethylene tetrafluoroethylene), and blends of the foregoing.

摘要： A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property.

摘要： Methods for the treatment of textiles used for facial masks assure for the inactivation of viruses captured by the textile. The aerosol droplets are absorbed by the textile, and any viruses in the water droplets react with a virucidal substance. The surface of textile fibers is first exposed to gaseous plasma to assure appropriate wettability. The textile is then soaked in a diluted water solution of a virucidal substance. The excessive water solution is optionally removed by draining, and the drained textile is then dried. The methods enable uniform coating of the textile fibers with an extremely thin film of virucidal substance. A typical concentration of the virucidal substance in the textiles treated according to the methods of the aspects of disclosed embodiments is about 10 g/kg. Such a small concentration is benign to humans but effectively inactivates the viruses that might be captured by the textile.

摘要： The present invention relates to fibers, particularly to as-spun fibers, having improved properties, in particular improved bonding performance and mechanical properties. In particular, the present invention relates to fibers comprising a metallocene random copolymer of propylene and one or more comonomers, said metallocene random copolymer having a broader molecular weight distribution. The present invention further relates to nonwovens comprising such fibers and to a process for producing such fibers and nonwovens. The fibers and the nonwovens of the present invention are characterized by improved properties, in particular improved bonding performance and mechanical properties, when compared to the prior art fibers and nonwovens.
