Thermal Properties of Non-Woven Composite

The research in the area of development of lightweight, skin-friendly, non-corrosive, environmentally safe, self-decontaminating ; durable and less bulky protective materials which reduce physiological burden and provide improved protection and safety resulted in three layered fabric composite FibertectTM. The non-woven activated carbon (ACN) fabric layer is sandwiched between two skin friendly non-woven rayon (CV) fabric layers and manufactured at Texas Tech University using the H1 technology needle loom Fehrer®AG. The adsorption capabilities, electrokinetic phenomena and antimicrobial activity of this fabric were previously thoroughly researched. Therefore, this paper will discuss about thermal properties and burning behavior of such non-woven composite. Thermal properties of such non-woven composite were determined using Micro Combustion Calorimeter (MCC) and Thermo gravimetric analysis (TGA). The surface and bottom edge ignition were applied according to ISO 6940:2004 and ISO 6941:2003 for vertically oriented specimens. The candle-like ignition is characteristic for Limiting Oxygen Index (LOI) determination according to ISO 4589:1996 in LOI Chamber (Dynisco).
