Mechanical Evaluation of the Production of Bamboo Charcoal/ Stainless Steel Complex Yarns and Knitted Fabrics
In this study, bamboo charcoal/ stainless steel complex yarns was made of stainless steel wires and polyester bamboo charcoal filaments using a rotor twister machine. The stainless steel wires served as the core yarns while the polyester bamboo charcoal filaments served as the wrapped yarns. The speed of rotor twister was set as 7000 to 11000 rpm and wrapped counts were 2 to 7 turns/ cm. Bamboo charcoal/ stainless steel complex yarns were with the tenacity as 3.08 g/d when manufacture parameters were speed of rotor twister as 8000 rpm and wrapped counts as 4.0 turns/ cm; moreover, when speed of rotor twister was at 7000 rpm and wrapped counts was 5.0 turns/cm, bamboo charcoal/ stainless steel complex yarns received the tensile strain as 24.91%. According to tensile strength test for knitted fabrics, when wrapped count was 4 turns/ cm, the knitted fabrics had its tensile strength as 214.49 N, and the vertical tensile strength was higher than the horizontal one. When the wrapped counts of bamboo charcoal/ stainless steel complex yarns was 6 turns/ cm, the knitted fabrics attained its tensile strain at 236.87%.
