摘要
Multifunctional metal composite yarns made of crisscross-section polyester (CSP), antibacterial nylon (AN), and stainless steel wires (SSW) were manufactured using a hollow spindle spinning machine. The core yarn, the inner wrapped yarn, and the outer wrapped yarns were SSW, AN, and CSP, respectively. Process parameters such as wrapping material content obviously influenced the tenacity, elongation, and surface morphology properties of the manufactured multifunctional metal composite yarns. These yarns were then woven into fabrics using a rapier loom. Woven fabric WC-8 was evaluated in terms of its mechanical properties, antibacterial activity, and electromagnetic shielding effectiveness (EMSE). Results showed that the use of SSW and AN in the metal composite yarns improved the antibacterial and EMSE of the woven fabric. Thus, these metal composite woven fabrics can be used in manufacturing personal protective clothing to protect humans from electromagnetic radiation and bacterial cross-infection.
