Development of nanoparticle as reinforcement in fabrics is a novel approach in engineering of polymeric composites Carbon nanotubes (CNTs), particularly have a great potential in improving nanofiber properties. In the present study, outstanding features of nanoparticles and electrospun nanofibers are translated into the body of PA/CNT nanofiber. This work aims at comparing the reinforcing impact of nonwoven, weft-knitted and woven fabrics on tensile strength . Composite PA/CNT nanofibers were produced by electrospinning and then converted into yarn. Then woven and weft-knitted fabrics were manufactured by means of these yarns. Also, nonwoven fabrics were made out of electrospun composite nanofibers. Results indicated that loading CNTs into nanofibers increased the tensile properties of nanofibers and hence the resultant yarn. Furthermore, utilization of carbon nano tubes as reinforcement could significantly enhance properties of these fabrics , respectively. Tenacity of the CNT-free nonwoven web sample, was found to be 3/89 MPa. By adding CNT to control sample, tenacity value was doubled.
