Abstract In polymeric bearing applications it was found that the polymer tends to wear more quickly than indicated in laboratory wear tests. The reason has been attributed to the effect of loading conditions and the generation of fatigue surface cracks. The current study investigated the effect of single imposed vertical crack in the Nylon 66 surface upon its wear behaviour in dry and water ...

Nylon fabric is man-made and contains chemicals as a result of which its ability to attract and retain the Divine principle in them is restricted. This makes the clothes made from nylon fabric Raja-Tama predominant. Negative energies such as ghosts from the spiritual dimension are attracted towards anything that is Raja-Tama predominant.
