Abstract

The invention discloses novel electromagnetic shielding textile fabric and its preparation method and belongs to the field of textile processing. By a magnetron sputtering technology, nano-silver, nano-copper and nanometer titania particles are respectively sputtered onto a fabric base material to form an uniform nanocomposite film so as to obtain the electromagnetic shielding fabric. The electromagnetic shielding fabric for children's garments has advantages of simple preparation technology, low cost, high binding strength of the film and the base material, uniformly and compactly distributed film, strong adhesive force and no environmental pollution, and has excellent electrical conductivity and electromagnetic shielding performance. Resistance can be less than 10 omega/cm, SE value reaches about 28dB, and more than 99% of electromagnetic wave is shielded. By means of rapid heat-conducting property of metal, the fiber fabric can have effects of regulating body temperature and making the winter warm and the summer cool. In addition, the fabric feels very soft and has excellent resistance to water washing.

Description

technical field [0001] The invention relates to a functional fabric, in particular to a novel anti-electromagnetic radiation textile fabric, which belongs to the field of textile processing. Background technique [0002] With the increasing popularity of electronic products in people's lives, the impact of electromagnetic waves on human health is becoming more and more obvious. How to reduce the damage caused by electromagnetic radiation to human body has attracted more and more attention. The human body is exposed to electromagnetic radiation for a long time, and the nervous system, cardiovascular system, endocrine system, reproductive system, etc. will be damaged to varying degrees. This is even more important for children who are growing up. In order to protect children from or minimize the harm of electromagnetic radiation, on the one hand, people shield the source of electromagnetic radiation to reduce the amount of radiation, and on the other hand, develop effective p...
