The existence of the electromagnetic radiation may lead to diseases, which also includes cancer and cause the repellence of electrical compatibility. The textiles which have electromagnetic shielding effectiveness become more important in modern life. In the research, the PET/ Ni-coated Copper composite yarn were made by the wrapping machine, which the core yarn is Ni-coated Copper wire and the wrapped yarn is PET filament. After that, the composite yarn is fabricated by the automatic sampling loom into woven fabrics and had the tests of mechanical properties and electromagnetic shielding effectiveness. The test results revealed that the EMSE of the PET/Ni-Cu complex woven fabrics is 32.28dB, which the test frequency is 900 MHz, laminated layer number is 3 and the laminated angles are 0°/45°/90°, respectively.

In this study, the covered yarn, composed of stainless steel wires as the core and bamboo charcoal roving as the sheath, is made on a ring spinning machine and then knitted into bamboo charcoal/stainless steel fabric by an automatic 14-gauge horizontal knitting machine. According to the test results, both far infrared emissivity and the anion count of bamboo charcoal/stainless steel fabric increase with an increase in bamboo charcoal content.
