Abstract: A nonwoven web comprising a layer of polymeric fibers, wherein, based on the total number of polymeric fibers, at least 10% the polymeric fibers in said layer are coarse fibers having a fiber diameter of 4 μm or more, and at least 10% of the polymeric fibers in said layer are fine fibers having a fiber diameter of 2 μm or less. Also described herein is a method for making the nonwoven web, comprising melt-blowing a polymer mixture comprising two immiscible or partially miscible polymers.

Abstract: Described herein is a continuous process for modifying the properties of polyester and polyester based fibers, such as a poly(butylene terephthalate) (PBT) fiber, comprising subjecting the PBT fiber to alkaline hydrolysis, and optionally further comprising functionalizing the PBT fiber by solution grafting such as fluorination. The alkaline hydrolysis and optionally subsequent functionalization such as fluorination process can be continuous, following the melt blowing/spinning or spun-bonding process. Also described is a nonwoven PBT fiber mat obtained by the surface modification process. Further described is a filtration device comprising the nonwoven PBT fiber mat.

Abstract: A method comprises providing a polymer. The polymer is heated to a first predetermined temperature so as to liquefy the polymer. The liquefied polymer is formed into a polymer fiber. The polymer fiber is cross-linked to form a cross-linked polymer fiber comprising a polymer network by at least one of cooling the polymer fiber to a second predetermined temperature lower than the first predetermined temperature or exposing the polymer fiber to a cross-linking stimulus, the cross-linked polymer fiber capable of being decross-linked by heating to a third predetermined temperature above a characteristic decross-linking temperature of the polymer.

Abstract: Embodiments described herein relate generally to adhesive alloys and their use in filter media, and in particular to adhesive alloys that can be melt blown onto a filter media layer, and which are thermally activated to bond the filter media layer to another filter media layer. An adhesive alloy is provided. A thermally activated adhesive has a first melting temperature. A polymer has a second melting temperature greater than the first melting temperature. A ratio of the thermally activated adhesive in the adhesive alloy is in a range of 5 wt % to 70 wt %.
