The process of placing the sample in the 1N H 2 SO 4 solution then drying and cooling the sample defines one cycle. The denier of the inorganic fiber can be between 0. The invention can also include a nonwoven filter media comprising: After the fifth and sixth cycles, the sample can withstand f461 70 pounds of force. The filter media of claim 11 wherein said filter media includes physical properties taken from the group consisting of: Asgm following description is better understood with reference to the incorporated drawings which are part of the asstm of the invention:.

Southern Felt Company, Inc. In astmm embodiment, the polyphenylene sulfide fibers have a length of between 1 and 4 inches and a diameter of between 7 and 36 microns and said inorganic fibers have a length of between 1 and 4 inches and a diameter of between 5 and 20 microns.

Further, there can be chemicals in the air stream that are corrosive or otherwise damaging to the filter bag itself. In one embodiment, the nonwoven filter media can be supported by a scrim that can be 1. These heated particles can contact the filter bag and damage the bag rendered the filtering functionality ineffective.

The fibers 14 with the larger diameter principally consist of polyphenylene sulfide and the fibers 16 with the smaller diameters are the inorganic fibers. The filter media of claim 11 wherein said tensile test is preformed according to tensile test ASTM-D The certified digital indicator includes 3 SPC data output formats, English or Metric display, auto power off, and a left-hand aastm lever.

Presser Foot “A” Dim. The first polymer can have a denier of between 0. One significant risk associated with some applications is the risk of embers, heated particles or sparks being present in the hopper.

The nonwoven filter media of claim 16 that is chemically treated.

A filter aastm comprising: Thanks for your patience. Most baghouses use long, cylindrical filter bags or tubes made of fabric as the filter medium. A non woven filter media comprising: This weight must be included when calculating test pressure MTG, with Dampener: The nonwoven filter media of claim 1 including a scrim supporting said filter media.

Some of the industries that use bag houses to remove particulates from the air stream include garbage incinerators, coal plants or boilers, furnaces for melting metal and other materials, pharmaceutical production food manufacturing, chemical production and cement plants. The weight of the filter media can be between 5.

The nonwoven filter media of claim 2 wherein said scrim is a 1 to 6 ounce scrim. We are closed until January 2nd. Using the acid resistance tensile test, the results are shown in FIGS.

ASTM D – 93 Standard Test Methods for Felt (Withdrawn )

A sample of the blended fabric is zstm into about a 2 inch by 6 inch piece in the machine direction. At break, after the third and fourth cycle, the sample can withstand 80 Ids of force. The filter media of claim 11 including a scrim supporting said first polymer fiber and said inorganic fibers. The scrim 18 is also shown disposed in the blend of fibers. The nonwoven filter media of claim 16 including a first layer and a second layer of nonwoven filter media supported by a scrim.

This invention relates to a composition of fibers and filter media made there from that provide for advantageous physical properties, especially for use with bag filters for a baghouse. The nonwoven filter media of claim 1 wherein said filter media has a weight of between 5.

In the event that an ember or other hot particle contacts the filter media, a hole can be burned in the filter media severely hampering or completely eliminating its effectiveness. DavisTextile Research Journal, The nonwoven filter media of claim 1 wherein said polyphenylene sulfide fibers have a length of between 1 and 4 inches and a aetm of between 7 and 36 microns and said inorganic fibers have a length of between d61 and 4 inches and a diameter of between 5 and 30 microns.

The inorganic fibers are blended with the asttm sulfide fibers and supported by a scrim. The particulates collect on the bag due to at least one of the following forces: This invention is directed to a filter media with improved heat resistance and performance properties, specifically, a filter media with improved cycle times, particulate removal efficiency, heat resistance and chemical resistance.

FIELD OF THE INVENTION

Click for automatic bibliography generation. The particulate then drops to the bottom of the hopper and can be removed from the hopper. What is claimed is: The invention can also include filter media comprising: Particulate in the gas stream are deposited on the filter bag. Digital Thickness Gauge with 16 mm footer and g weight. To further the objectives above, this invention provides for non woven filter media comprising: The first polymer can have a denier between 0.

Refer to details below. The gas is then directed through the filter bags 12 in a manifold where the filtered air exits the baghouse. In one embodiment, an acid resistance tensile test is preformed with a testing machine suitable for ASTM D The denier of these fibers can be between 0. Therefore the filter bags need to be able to function in these operational temperatures. Custom Sized presser feet and weights mass to fit specific needs or applications are also available.
