摘要： The disclosure includes, in some embodiments, a filter element that includes a first porous outer layer formed from a nonwoven material, a second porous outer layer formed from a nonwoven material, and at least one inner porous layer formed from a high loft nonwoven material (or other suitable material) disposed between the first porous outer layer and the second porous outer layer. The high loft nonwoven material has a three dimensional matrix formed by entangled and bonded fibers that cooperate to form a plurality of three dimensional interstices between the fibers for maintaining an open and tortuous flow path for fluid to pass through. The filter element also includes filter aid particles dispersed in the interstices of the high loft nonwoven material.

摘要： A fiber bed mist eliminator has a fiber bed which is formed of a composite fiber bed collecting media strip including a collection layer which is not subjected to needle punching. The fiber bed can be made very thin while retaining high efficiency in removing small particles of aerosol from a gas stream passing through the fiber bed. The fiber bed collecting media strip lends itself to be applied to the mist eliminator by spirally wrapping the element onto the mist eliminator. The fiber bed collecting media strip can overlap itself to seal at the locations where the fiber element overlaps itself. The fiber bed collecting media strip can be provided to the field in different formats for use in making a mist eliminator fiber bed.

摘要： Fibrous structures containing immobilized particulate matter and processes for making them are disclosed. These structures may be used for filters and for fabrics including chemical defense garments and others. The fibrous structures have webs containing composite fibers having a lower melting component and a higher melting component. The particles are distributed into the interior of the web and fused to the low melting component of the individual fibers without substantially reducing the available surface area of the particle. A fibrous structure of a composite staple having a nylon sheath and a polyester core, with activated carbon particles bonded to the sheath is specifically disclosed. The processes for producing such a fibrous structure include carding a web of staple fibers and distributing particulate matter therein, air laying a web of staple fibers and particulate from a suspension thereof between two wet formed layers of staple fibers. One or more additional layers of nonwoven, woven, or knit webs or fabrics may be bonded thereto.
