Thus, a non-woven fiber fabric which is substantially free from a solvent, different from the case of spinning a polymer solution, but yet has an extremely small fiber size (diameter of 0.5 μm or less) is provided. The non-woven fiber fabric comprises an olefin-based thermoplastic resin fiber, said fiber having an average fiber size of 0.01-0.5 μm, and said non-woven fiber fabric having an average pore size of 0.01-10.0 μm and being free from a solvent component. | 05-16-2013 |
| 20130137329 | MELT BLOWN FIBER - Melt-blown fiber having an average diameter of not more than 5.0 μm, said fiber comprises at least 85 wt.-% of a propylene copolymer, wherein • said melt blown fiber and/or said propylene copolymer has/have a melt flow rate MFR | 05-30-2013 |
| 20130337714 | Glazed Nonwoven Fabric and Methods of Manufacture - A glazing method for improving abrasion resistance using a heated smooth roll to melt the lower-melting-point portion of bicomponent fibers as the spunbond web passes over the heated smooth roll. Because there is no external pressure exerted in a nip by an opposing second roller, as in calendering, the outer surface of the web which does not contact the heated smooth roll remains essentially unchanged and the nonwoven fabric exhibits no compression as a result of the glazing process. The roll temperature and dwell time (roll diameter, wrap angle and line speed) are controlled for the purpose of surface treating only one side of the nonwoven fabric to improve abrasion resistance while allowing the air permeability and web thickness to remain essentially unchanged. | 12-19-2013 |
| 20140273703 | SERIALLY DEPOSITED FIBER MATERIALS AND ASSOCIATED DEVICES AND METHODS - Fibrous materials and methods of manufacturing fibrous materials are disclosed. In particular, this application discloses methods of making and processing serially deposited fibrous structures, such as serially deposited fibrous mats. Serially deposited fibrous mats may be used in implantable medical devices with various characteristics and features. Serially deposited fibrous mats of various mat thickness, fiber size, porosity, pore size, and fiber density are disclosed. Additionally, serially deposited fibrous mats having various amounts of fiber structures (such as intersections, branches, and bundles) per unit area are also disclosed. | 09-18-2014 |
| 20140323005 | SURFACE COATING AND FUSER MEMBER - Described is a fuser member having a substrate and a surface layer disposed on the substrate. The surface layer includes a non-woven polymer fiber matrix having dispersed throughout a siloxyfluorocarbon (SFC) networked polymer and a fluorinated polyhedral oligomeric silsesquioxane. | 10-30-2014 |
| 20150111456 | MELT-SPUN POLYPROPYLENE FINE-GRADE NANOFIBROUS WEB - The present invention is directed toward a to fine-grade stand-alone nanoweb and nanofibrous membrane comprising a nanofiber network with a number average nanofiber diameter less than 200 nm and the mean flow pore size less than 1000 nm that yield the selective barrier medium with a superior balance of flow versus barrier properties. | 04-23-2015 |
| 20160032505 | ELECTROSPINNING OF PTFE WITH HIGH VISCOSITY MATERIALS - An improved process for forming a PTFE mat is described. The process includes providing a dispersion with PTFE, a fiberizing polymer and a solvent wherein said dispersion has a viscosity of at least 50,000 cP. An apparatus is provided which comprises a charge source and a target a distance from the charge source. A voltage source is provided which creates a first charge at the charge source and an opposing charge at the target. The dispersion is electrostatically charged by contact with the charge source. The electrostatically charged dispersion is collected on the target to form a mat precursor which is heated to remove the solvent and the fiberizing polymer thereby forming the PTFE mat. | 02-04-2016 |
