FRICTION COEFFICIENT OF THE SPUNBOND NONWOVENS

Friction force that can be defined as the force resisting to the movement between two surfaces contacting with each other which plays an important role in textile industry. during usage, the fabrics continue to friction against the textile or other surfaces; because of this problem fabric surface structure deteriorates. therefore, most scientists have designed different methods in order to estimate surface properties and friction of fabric before usage. in this study, friction experiments have been performed by designing and manufacturing two different systems which work as a horizontal platform and inclined plane. the study has tried to investigate friction properties of polypropylene (pp) nonwoven fabric samples which are produced by spunbond methods (filament laid and thermal bonding) with different weight. while the selected fabric samples weight increase, it has been seen that high friction force becomes effective until a certain weight after when a low friction force occurs because of more stable structure. in addition, it has been observed that the higher is vertical force (load) applied on specimens, the lower coefficient of friction. these results shows that both measurement methods have similar tendencies
