The Process and Property Characteristic of Electromagnetic Shielding Functional Warp Knitted Composite Fabrics
The scientific progress has improved human life quality, meanwhile today's high-stress lifestyle has resulted in a rising demand for health care and well-being products. The high technology products and innovation make our life more convenient and at the same time the negative effects, such as electrostatic and electromagnetic wave. High electromagnetic wave affects the human body in different ways. Technological innovation and product aesthetics are both important for modern life quality. Companies have invested in research, development and essential household items to improve the lives such as thermal retentivity and antistatic. In this study, PET fiber was used as warp, and PET fiber, bamboo charcoal nylon fiber and stainless steel fiber employed as weft to weave three groups of resilient warp knitted fabrics. Then various examination have been conducted, including electromagnetic shielding effectiveness, tensile strength test, tearing strength test, burst strength test. The results indicate that the electromagnetic shielding effectiveness of bamboo charcoal / stainless steel resilient warp knitted fabrics attained 35 dB and the shielding achieved 99.9 %. The tensile strength of bamboo charcoal / stainless steel resilient warp knitted fabrics (weft) reached 26 MPa.
