Main Methods To Abrasion Resistance Of Fabric

The measurement of abrasion resistance, usually by the weighing of a material sample before and after subjecting it to a known abrasive stress throughout a known time period, or by reflectance or surface finish comparisons, or by dimensional comparisons.There are three main methods, that is, end point method, mass loss method, and appearance change method.
End point method: when two yarns of different directions of woven fabric are broken, when one yarn of knitted fabric is broken, when a hole that is not less than 0.5mm appears in the nonwovens, and when the whole velvet of the pile fabric is worn off, record the friction times as the abrasion resistance index.
Mass loss method: The sample was weighed as mass A before the test and as mass B after a certain number of friction times so that take the mass loss or percentage of mass loss as an index of abrasion resistance.
Appearance change method: after a certain number of friction times, observe the appearance changes, such as color change, pilling phenomenon, wear degree, the degree of appearance change as the index of abrasion resistance.
