Nonwoven Flame Retardant and Antibacterial Protection Composite

This paper used lightweight, skin-friendly three layered fabric composite of non-woven activated carbon (ACN) fabric is sandwiched between two skin friendly cellulose (FR Rayon) layers. This composite made of non-woven has been developed by Chemical Engineers at The Institute of Environmental and Human Health at Texas Tech University to fight against chemical and biological agents. In previous our paper this composite has shown the perfect protect against fire based on the positive influence of carbon layer with high flame protection, on composite material. , the carbon layer (ACN) does not burn at room condition at all. For its burning it is necessary to have at least 47 % of oxygen which indicates its very high LOI value. The present paper discusses about selecting antimicrobial treatments which provides the optimum protection against Gram positive and Gram negative bacteria for composite materials. Antimicrobial protection against Staphylococcus aureus and Klebsiella pneumoniae organisms is determined according to EN ISO 20645:2004. Flame retardancy of composite and its layers was determined trought its burning behavior. Two standard methods, ISO 6940:2004 Textile fabrics – Burning behavior – Determination of ease of ignition of vertically oriented specimens and ISO 4589:1996 – Plastics – Determination of burning behavior by oxygen index using Limiting Oxygen Index (LOI) Chamber by Dynisco, were applied respectively.
