A plastic fabric using a different-melting point core-sheath structure fiber comprises a top layer fabric, a support layer, and a bottom layer fabric. The top layer fabric is fabricated with a different-melting point fiber, which comprises a core-sheath structure including a core and a sheath wrapping the core. The core has a melting point higher than that of the sheath. The bottom layer fabric is disposed on one side of the top layer fabric. The support layer is disposed between the top layer fabric and the bottom layer fabric. As the core has a melting point higher than that of the sheath, the different-melting point fiber has superior dimensional stability and permanent shape memory after heat treatment for plastic shaping.

An electrically conductive yarn including an elastomeric monofilament and an electrically conductive thread crocheted about the elastomeric monofilament. A method of forming an electrically conductive fabric including providing an elastic monofilament, enclosing the elastic monofilament with a conductive thread by crocheting, thereby producing a conductive elastic yarn and forming an electrically conductive fabric from the conductive elastic yarn and an electrically conductive fabric formed thereby.
