摘要:
The web of the invention can comprise a super absorbent layer that can act as an moisture sensitive fuel shut-off valve, absorbent, adsorbant or reactant. The web of the invention can comprise a super absorbent fabric or layer made of a superabsorbent particle or fiber. Fluid, gas or liquid, that flows through or by the assemblies of the invention can have any gas, liquid or solid material dispersed or dissolved in the fluid interact with the super absorbent particulate. The structures of the invention can act simply as flow-by reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters.

The web of the invention can comprise a super absorbent layer that can act as an moisture sensitive fuel shut-off valve, absorbent, adsorbant or reactant. The web of the invention can comprise a super absorbent fabric or layer made of a superabsorbent particle or fiber. The web can comprise a nanofiber layer having dispersed within the nanofiber layer a super absorbent particulate and optionally a second particulate material that can act as an absorbent, adsorbant or reactant. Fluid, gas or liquid, that flows through or by the assemblies of the invention can have any gas, liquid or solid material dispersed or dissolved in the fluid interact with the super absorbent particulate. If needed these materials can also react with, be absorbed by, or adsorbed onto, the active particulate within the nanofiber layer. The structures of the invention can act simply as flow-by reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters that can filter particulate from a mobile fluid in a flow-through mode while simultaneously reacting, absorbing, or adsorbing materials from the mobile fluid.

摘要:
An air filter having a low pressure drop and adsorbent capabilities when placed in a fluid stream is disclosed. The air filter contains activated carbon incorporated into a filter media that can be shaped into a fluted configuration. The fluted shape is maintained during operation of the air filter through the use of flow restrictors along the length of the flute. The fluted material can be rolled or stacked.
摘要:
A surface energy gradient on a fluid-impervious surface and method of its creation comprising the steps of a) Exposing a base surface having a proximal and a distal portion to a first solution comprising at least one molecule of the formula X-J-M1 wherein X and M1 represent separate functional groups and J represents a spacer moiety that, together, are able to promote formation from solution of a self-assembled monolayer for sufficient time to form a monolayer surface [with] having a uniform surface energy on the base surface. b) Removing a portion of the monolayer of (a) such that a portion of the base surface is again fully or partially exposed. (c) Exposing the portion of the base surface from (b) to at least one other molecule including a functional group having a different surface energy from that of the functional group removed in (b) such that a surface energy gradient from a proximal location to a distal location is formed.

A moisture-retentive fabric medium includes a hydrophilic, thermoplastic polyester fiber as a blend of from 10-905% or 20-80% by total weight of textile fibers and 90-10% or 80-20% by total weight of hydrophilic textile fibers and less than 0.5% by weight of total fabric medium as microfibrillated cellulose fiber and less than 0.05% by weight superabsorbent polymers, the polyester having a melting point between 190-500 F when measured in accordance with ASTM D-3418.
摘要:
A filter and filter media configured and arranged for placement in a fuel stream is disclosed. The filter and filter media allow for filtering of liquid fuels, such as diesel fuel. In certain embodiments the filter media includes a media fiber, such as melt blown polyester; and a scaffold fiber, also such as such as melt blown polyester, having a larger diameter than the media fiber. The media and scaffold fibers combine to create a media structure having low solidity and relatively low compressibility, and which contain a pore structure that avoids premature fouling of the filter by fuel degradation products.
