Shear spun sub-micrometer fibers

A process including shearing a first dispersion medium and a second dispersion medium under conditions that precipitate a plurality of polymeric fibers; and collecting the plurality of polymeric fibers at a rate of at least 300 grams/hour. The first dispersion medium is a solution including at least one polymeric component. The at least one polymeric component includes a polyetherimide component selected from the group consisting of polyetherimide homopolymers, polyetherimide co-polymers, polyetherether ketones homopolymers, polyetherether ketones copolymers, polyphenylene sulfones homopolymers, polyphenylene sulfones copolymers, and combinations thereof. Products produced by the process can be non-woven paper, medical implants, ultra-fine filters, membranes, hospital gowns, electrical insulation paper, honeycomb structures and personal hygiene products, dialyzers, blood, oxygenator filters, intravenous (IV) filters, diagnostic test filters, and blood/apheresis filters.

CROSS-LAPPED MULTILAYER FIBROUS BATT AND METHOD OF MAKING THE SAME
20180363183 · 2018-12-20 · ·

A cross-lapped multilayered batt, and a method of making the same is presented. The batt includes one or more layers of a carded web of staple fibers, and one or more continuous filament fiber layers. At least some of the staple fibers and, in some instances, some of the continuous filament fibers are mechanically entangled through a thickness of the batt. The method includes folding both the carded web and the continuous filament fiber layers together, and subjecting the folded layers to a needle-punching process to impart structural stability and enhance the Z-directional strength of the batt.
