Important Points Require Consideration Before Abrasion Tests

A number of important points require consideration before abrasion resistance tests are carried out. The choice of the method may be governed by the type of apparatus available, the precision demanded and so forth.

Some of the more important points are condition of the specimen, choice of testing instrument, choice of abrasive motion, direction of abrasion, choice of abradant, backing the specimen, cleanliness of the specimen and instrument, tension on the specimen, pressure between abradant and specimen, end-point of the test etc.

 Now there are various abrasion resistance testing instruments available for example, the WIRA abrasion tester, the LIRA abrasion tester, the Taber abraser, the Shiefer machine, the Wyzenbeek abrasion tester, the Stoll universal wear tester, the LINRA wear tester, the BFT abrasion tester etc. The abrasion tester we used here is made by Qinsun Instrument. In this instrument abrasion surfaces wrapping by sand paper are used to abrade the fabric samples. A counter is used to count the no. of abrasion. This is an electrical tester.

Abrasion Tester is used to determine the abrasion resistance of fabrics when rubbed against a standard abradant or a wire mesh screen with a backward and forward motion over a curved surface. Particularly it’s suitable for? automotive and furniture industry fabric manufacturers working to US standards.

Determination of air permeability of a fabric-air permeability tester

Fabric air permeability is a measure to what extent it gives air passing through the fabric. Air permeability, a given area in the vertical direction of the air flow rate, a given time period, is measured by the fabric test area inside the pressure difference of the fabric. Basically, it depends on weight, thickness and porosity of fabric. The porosity of fabric is the demonstration of the air gap as a percentage within fabric. It has been important for especially the tent fabric, parachute fabric, raincoat fabric and garment, the fabric used in air bags, industrial filters and sail cloth. Moreover, when thermal properties of clothing and body interaction are taken into consideration, there has been the effect of air permeability. there is an instrument which is designed to test the air permeability of fabric on the market .it is air permeability tester . Air permeability is an important feature of fabrics (Sundaramoorthy et al., 2011) and is one of the main factors affecting the t...

How To Process The Elmendorf Tear Strength Test

The Elmendorf tear tester has been developed specially for the paper industry and is outstanding for simplicity of operation and high measurement accuracy. The exchangeable pendulum is equipped with a pneumatic sample clamp. The initiation and return of the pendulum, as well as sample cutting is completely automatic. The device is operated via an integrated touch screen, where the test method can be selected, specific settings can be adjusted, and, after the measurement, results and statistics can be  displayed.Each pendulum is supplied with the appropriate control weight so that, with the help of the service program, it can easily be checked for functionality and balance. The Elmendorf tear test Procedure:     Cotton fabric was taken.     Warp and weft direction of the fabric was identified.     Two strips were cut from the fabric in both directions having dimensions of 100 x 63.5 mm.     The sample was then fixed in the jaws of the ...

3 main functional values of the Burning Manikin System

3 main functional values of the Burning Manikin System 1) Research on the heat transfer mechanism of individual soldier's flame retardant equipment By simulating the battlefield fire conditions of different intensities, the changes of human skin surface heat flow and skin temperature by burning dummies, a good human body-clothing-fire environment conditions are created, and the individual soldiers are flame retardant The study of equipment heat transfer mechanism provides an important research method. 2) Research and screening of flame retardant fabrics for individual soldier equipment Quantitatively test the flame retardant properties of different individual soldier equipment fabrics through the burning dummy system, guide the research on flame retardant fabrics, and screen out flame retardant fabrics with excellent performance. 3) Structure and style design of individual soldier's flame retardant protective equipment The structure and style of individual soldier's flame r...
