MULTI-DECONTAMINATION COMPOSITE WIPE AGAINST CBR AGENTS

Abstract

Elimination of harmful contaminants from humans and equipments comes under the category of decontamination of CBRN contaminants. The CBRN contaminants stand for Chemical, Biological, Radiological and Nuclear contaminants. The major objective is to minimize the burden of contaminations and to prepare the obtained minimized contaminated material for permanent disposal activities and protective storage. For decontamination chemical technique is very efficient and cost effective. Sometimes both humans and materials get contaminated with CBRN contaminants. Small amount of contaminants exposure cause change in cell structure. Due to higher amount sometimes death also occurs. Therefore, decontamination is very important for humans, at the same time it is very vital to minimize the waste and cost for the task required for personal decontamination. Present work deals with the effectiveness of non woven composite wipes of different nano fibers and fibers along with a nanoemulsion for the decontamination of CBR contaminations. Decontamination in general is defined as the removal of hazardous material from areas where it is not wanted. Decontamination is applied to reduce the dose that worker may receive from a component or surface, to reduce the potential for airborne Chemical, biological, and radiological, (CBR) agents, or to reduce the disposal cost associated with the component or the material. A nanofibrous web was developed which is based on Rayon fiber, Zinc titanate nanofiber and nano ZnO loaded polyester fibers. Because of its super-light weight, excellent resistance to heat radiation, and chemical and bacterial decontamination properties, it is used as a thin interlayer incorporating with highly porous fibrous materials so as to get high absorbency and entrapment properties. The results indicate that the decontamination of CBR contaminants can be effectively improved by adding appropriate nanofibers.
