TY - JOUR TI - Continuous nanofiber yarns twisted through three-dimensional high-speed swirling airflow AU - He Jian-Xin AU - Zhou Yu-Man AU - Qi Kun AU - Liu Fu-Juan JN - Thermal Science PY - 2013 VL - 17 IS - 5 SP - 1269 EP - 1276 PT - Article AB - A new method is proposed to fabricate continuous twisted nanofiber yarns. Nanofibers are bunched by a double conjugate electrospinning, and then twisted through a three-dimensional high-speed swirling airflow. Its principle and process are analyzed theoretically, and the airflow field inside the nozzle chamber is studied numerically, and mechanical properties of nanofiber yarns at different spinning conditions are systematically discussed.
