Title: Frictional study of polymeric textiles
Author: Rajanala, Ranjeet
Abstract: The frictional properties of textile materials have been of interest to material scientists and textile technologists for a number of years . Friction is defined as the resistance to motion when two bodies in contact are set to a relative motion . Friction is the principal physical property - that holds the fibers together to form a fabric . Friction is a complex physical and mechanical phenomenon . Polymeric materials such as textiles fail to obey the classical Amontons' law of friction . This thesis work endeavors to prove the failure of Amontons' classical law of friction using a statistical approach . The nonlinearity between the friction force and the normal load resulted in the de \'elopment of a normalized friction factor , "R" The novel normalized friction factor has been used to evaluate the frictional properties of a set of woven and nonwowen fabrics . In addition , research efforts also focused on understanding the surface mechanical properties of needlepunched -thermalbonded nonwoven substrate . The sliding friction apparatus has been conveniently used to characterize the frictional properties of the nonwoven fabric . Results on the frictional study of the nonwoven fabric have been very promising and have proved the effectiveness of the novel friction factor . The thesis also presents a critical appreciation of previous works on the frictional properties of polymeric textiles .
