Chooseing Best Quality Of Filter-cloth
Filter Cloth is the device of filtration process
. Filter cloth is of woven or non woven fabrics of fiber, cotton or wool. The woven filter cloth is knitted as normal cloth, but non woven is sediment ed.
Non woven filter cloth is generally made by putting small fibers in the form of sheet or web and then joining them either mechanically or chemically with an adhesive. Non woven filtration fabric is less strong, it can be tearing easily. The woven category of filter cloth is stronger than non woven.
Filter cloth's robustness is calculated for tensile and bursting strength. Filtration levels are secondary to the strength measurements. Liquid filters are those who found in oil filtration system, are calculated for strength and filtration capacity also. The flow of liquid is calculated in pounds per square. Tensile strength is also calculated in pounds. The specific of measurements is depending upon the type of fabric and the objective 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 according to the specifications.
Measurement of filtration grade of filter cloth is done in microns. Micron is similar word 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 trap particles that have diameter of 10 micro meters. Typically human hair's diameter is about 70 micrometer. Usually bacteria are between 1 to 10 microns.
Efficiency of Filter Cloth:-
The efficiency of a filter cloth denotes accuracy of filtration capacity. An efficiency level of 50% at 10 microns implies that filter will catch half of all particles 10 microns in size, which is a typical 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.

Usages of Filter Cloth:-
Filter cloth is used in various specialties, which are as follows:
Hygiene
In hygiene filter cloth is used in baby nappies, feminine hygiene, adult incontinence products, wet wipers, bandages and injuries dressings.
Medical
In medical field filter cloth is used in isolation gowns, surgical gowns, surgical drapers and covers, surgical scrub suits and surgical masks.
Engineering
In engineering area filter cloth is used filtration system of gasoline, oil and air, coffee or tea bags, medical laboratories, refineries and food processing plants.
Geotextiles
As a Geo-textile it is used in soil stabilizers, erosion control, canals engineering, water flow systems etc.
