Elastic fasciated yarn resistant to electromagnetic radiation and fabric obtained by weaving same

Abstract

The invention relates to an elastic fasciated yarn resistant to electromagnetic radiation and fabric obtained by weaving the same. The core yarn of the elastic fasciated yarn is made of an elastic fiber filament, wherein the outer wrapping yarn is made of conductive polyester / metal filament fasciated yarn, the core yarn of the conductive polyester / metal filament fasciated yarn is made of a metal filament, and the outer wrapping yarn is made of a conductive polyester fiber filament. The fabric obtained by weaving the elastic fasciated yarn resistant to the electromagnetic radiation has a transverse elongation of 70-120%, a transverse recovery of 96-100%, a longitudinal extension of 95-130%, a longitudinal recovery of 95-100%, a creasy recovery angle of 300-330 degrees, the flatness of appearance of 4-5 grade and an electromagnetic shielding value of up to 7-27 dB against 1.5 GHz electromagnetic waves. According to the elastic fasciated yarn resistant to the electromagnetic radiation and the fabric obtained by weaving the same, the elastic fiber filament is adopted as the core yarn, and the conductive polyester / metal filament is adopted as the outer wrapping yarn, and therefore the fabric obtained by weaving the elastic fasciated yarn resistant to the electromagnetic radiation not only is high in shape retention, but also has two effects of reflection and absorption of the electromagnetic waves at the same time, so that the shielding effectiveness of the fabric against the electromagnetic waves is improved.

Description

technical field [0001] The invention belongs to the field of novel spinning, and relates to an elastic wrapping yarn for preventing electromagnetic radiation and a fabric prepared therefrom. Background technique [0002] With the rapid development of miniaturization and high integration of modern electronic equipment, the electromagnetic environment in which human beings live is becoming more and more complex. At present, electromagnetic radiation has become the fourth largest public hazard after noise pollution, air pollution and water pollution. Electromagnetic radiation not only interferes with the normal operation of electronic equipment, but also has great harm to human health, and is called an "invisible killer". A large amount of scientific evidence shows that long-term exposure to electromagnetic radiation can easily lead to metabolic disorders, decreased body immunity, rough skin, etc., and even induce leukemia and various types of cancer. With the continuous enha...
