COEFFICIENT OF FRICTION OF THE FABRIC

Coefficient of friction:

The coefficient of friction of the fabric tells about the frictional characteristic of the fabric surface. The coefficient of friction of a fabric is the tangent of an angle at which a block covered with fabric begins to slide due to its own weight when it is kept over the inclined surface covered with same fabric. This is property which is directly associated with the smoothness of the fabric. The factor affecting the coefficient of friction are given below:

Type of yarn:

The fabric made of spun yarn starts to slide at a higher angle than continuous filament yarn because the spun yarn has a much-broken surface area in comparison of continuous filament yarn. The continuous filament yarn having lower TPM (turns per meter) starts to slide at a lower sliding angle. It is happed just because of a low degree of twist present in the yarn.

Type of material: 

The silk fibre has the lowest sliding angle among all the natural fibres. Most of the natural fibres have greater sliding angle than synthetic fibres.

Weave of the fabric: 

The satin weave has more smoothness than plain weave. This surface smoothness helps to reduce sliding angle in a satin weave.

Finishing agent used in the fabric:

The coefficient of friction of fabric is directly associated with the final fabric finish.
