Measurement and assessment of abrasion of fabric

Measurement of abrasion resistance of fabric

Factors of abrasion testing that affect the measurement

Types of abrasion and testing abradant affect the result of testing abrasion properties.

I.e. - The number of different abradants in abrasion tests like standard fabrics, steel plates, abrasive paper or stones aluminium oxide or silicon carbide create variation in abrasion.

The severity and the type of action are different in each case.

For the test to be accurate with actual wear in use, it is advisable that the abrasive should be similar to that encountered in service in actual use.

The action of any abradant used for the test should be constant throughout the test without wearing itself. (If Abradant itself starts to wear during testing so it constantly creates variation in further process. To reduce this coated material from the abraded sample, such finishes are generally used.)

The pressure between the abradant and the sample also affects the severity and rate at which abrasion occurs.

Pressure between them creates seriously alters the ranking of a set of fabrics when using a particular abradant.

During measurement, the higher speed of the wearing action generally increases the temperature of the sample. This may affect the physical properties of thermoplastic fibres and so fabric.

When the sample is placed for abrasion measurement, the Tension applied on the sample need to be proper because it is reproducible for determining the degree of mobility of the sample under the applied abradant.

In many fabrics Direction of abrasion in the case of the warp, direction differs from that of the weft direction.

In general, the rubbing motion is designed such a way that it tends to eliminate and minimize the above effects.

The methods used for measuring abrasion may be described by the equipment, the test head movement or testing device setups like an inflated diaphragm, flexing and abrasion, oscillatory cylinder, rotary platform, uniform abrasion, and impeller tumble.

Assessment of abrasion damage

In abrasion damage assessment, it can be approached either by a abrade sample until it creates a hole and recorded significant abrasion or by abrade sample for a specific time and conditions.

Abrade the sample until a predetermined end-point such as a hole, and record the time or number of cycles to this.

In both ways, Abrasion needs to create up to some aspect of the abraded fabric such as a change in appearance, loss of mass, loss of strength change in thickness, or other relevant properties.

In the comparison of these methods, the second is more accurate due to its fixed time for testing. However due to complications like lack of relations between these two methods and variable results. These are not ideal conditions for measuring abrasion damage.
