金属纤维混纺屏蔽织物屏蔽效能 总被引:7,自引:0,他引:7
依照电磁屏蔽的基本理论,在分析金属纤维屏蔽织物屏蔽机理的基础上,给出了估算织物电磁屏蔽效能的计算方法并作了简要分析,探讨了金属纤维混纺纱的结构、金属纤维含量与织物紧度对屏蔽效能的影响。分析表明,屏蔽织物中导电网网间孔缝线经对屏蔽效能有较大影响,而织物总紧度并不总是与织物的屏蔽效能成正比。 相似文献

As interventional radiology procedures become more sophisticated, so must the radiation shielding apparel protecting the patients and medical personnel. Conventional radiation shielding apparel is constructed from lead impregnated sheet material which has issues with lead toxicity and user discomfort. This research constructed a more sophisticated material consisting of a textile platform with a bi-layer, non-lead coating with the objective of achieving a 90% attenuation percentage. If radiation shielding material can be produced on a common textile substrate rather than on unyielding sheet material, then it has the potential to be optimised through integration into a textile manufacturing environment. The material was constructed using a solvent casting technique which coated Barium Sulphate (BaSO4) or Sodium Tungstate (Na2WO4) or Bismuth Oxide (Bi2O3) onto a textile substrate. The results showed that the difference in attenuation between the samples produced and the lead equivalent material ranged from 0.76 to 2.1%. Future research can optimise these results by applying textile engineering processes to the coating techniques and also the textile platform itself. This would mean that radiation shielding apparel would not be a simple adaptation of barrier material but be created for ergonomic fit and comfort from the material design stage. 相似文献

In recent years, the use of electrical and electronic devices has grown rapidly. These devices cause electromagnetic interferences, which could threaten human life. In order to solve this problem, intensive research to develop textile surfaces having electromagnetic shielding properties continues. In this paper, we study textile surfaces knitted with conductive copper and stainless steel wires wrapped with acrylic yarns and also core yarns produced by using conductive yarns to test the electromagnetic shielding properties of the fabrics. It was concluded that the knitted structure of the fabrics affected the electromagnetic shielding effectiveness (EMSE). Besides, the fabrics knitted on a double needle bed of the knitting machine with higher amounts of conductive yarns and unit weights could not provide the targeted improvement in the EMSE values with respect to the fabrics produced on a single needle bed of the knitting machine. 相似文献
