Abstract

In this research, a type of bamboo charcoal polyester (BC-PET)/antibacterial nylon(AN)/stainless steel wire (SSW) metal composite yarn was prepared with a hollow spindle spinning machine, which using the SSW as the core material, the BC-PET and AN as the outer and inner wrapped yarns, respectively. The wrapping numbers was set at 8.0turns/cm for the produced metal composite yarns. Furthermore, a type of plated knitted fabric was designed and produced by using the automatic jacquard knitting machine. The plated knitted fabric presents the BC-PET/AN/SSW metal composite yarn on the knitted fabric face and the crisscross-section polyester (CSP) on the knit back. The effect of lamination numbers and angles on the electromagnetic shielding effectiveness (EMSE) were discussed in this study. EMSE measurement showed that the lamination angles will influence the EMSE, but not affect the air permeability. Finally, a novel EM shielding socks was designed with the produced plated knitted fabric. Finally, the performance of thermal resistance and evaporation resistance was also test usingThe sweating guarded hot plate apparatus.

Highlights

With the development of science and technology, more and more electronics products are present in our daily life
We mainly study the effect of lamination number and angles on the air permeability and EM shielding properties for the produced plated EM shielding knitted fabric used as socks
To make the produce EM shielding socks have great water transport ability and elastic properties, the 25 denier spandex was back plated with crisscross-section polyester (CSP) yarn and the produced metal composite yarns as the front face of plated knitted fabric and the EM shielding socks was fabricated on automatic jacquard knitting machine

Summary

Introduction

With the development of science and technology, more and more electronics products are present in our daily life. It will cause various electromagnetic (EM) wave reveal and pollute the human living space. Various forms of electromagnetic waves cause electrical and electronic malfunctions and link to serious health problems, such as leukemia, brain tumors, Alzheimer’s disease, sleeping problems, and depression. Compared to other EM shielding materials, EM shielding fabric could meet the need of the people's daily life and could protect the human body from EM radiation. The EM shielding fabric is more close to people's life [1,2,3]
