Agglomerates of delusterant particles located near the surface of sythetic fibers cause asperities .

In this model the rough surface of the contact is idealized as a plane with some asperities . The sticking effect is also considered . The variation of contact resistance with contact force is calculated .

The larger the surface roughness and the sharper the asperities the greater the asperity contact load .

Merchant thought that minute asperities existed at the chip-tool interface and the fluid was drawn into the interface by the capillary action of the interlocking network of these surface asperities .
