Filter-Cloth
Non woven filter cloth is typically manufactured by putting small fibers in the form of sheet or web and then binding them either mechanically or chemically with an glue. Non woven filtration fabric is less robust, it can be tear easily. The woven category of filter cloth is stronger than non woven.
Filter cloth's strength is considered for tensile and bursting strength. Filtration degrees are secondary to the
strength measurements. Liquid filters are those who found in oil filtration system, are Calculated for strength and filtration capability also. The flow of liquid is calculated in pounds per square. Tensile strength is also evaluated in pounds. The specific of measurements is depend upon the type of fabric and the purpose of the fabric. An absolute rating of 10 microns does not imply a good filter.
Now a days filter cloth is available in different colors and sizes in accordance to the specifications.
Measurement of filtration grade of filter cloth is done in microns. Micron is similar term to micro meter. The micron is the smallest scale on which filter cloth performs filtration process. Rating of 10 microns mean that the filter can capture elements that have diameter of 10 micro meter. usually human hair's diameter is about 70 micrometer. generally bacteria are between 1 to 10 microns.
capability of Filter Cloth:-
The effectiveness of a filter cloth denotes accuracy of filtration degree. An efficiency level of 50% at 10 microns denotes that filter will trap half of all elements 10 microns in size, which is a standard rating. If a filter is able to filter 98% or higher of the measured micron level. Good filters should have a high-efficiency rating for the size elements that are mean to be filtered. Liquid filters having absolute rating at 10 microns are known as very effective filters.
