A summary of research on heat resistant fabrics for protective clothing.
Department of Textile Materials and Management, North Carolina State University, Raleigh, North Carolina, 1988 Jan; :1-25
Research on heat resistant protective fabrics was reviewed. Particular attention has been given to the measurement of the thermal properties of flame and heat resistant materials, resulting in the development of many different methods for measuring fabric flammability and heat transmission. The measurement of ignition time, ignition temperature, shrinkage, thermal conductivity, and heat transmission have been stressed. Vertical flame tests are simple means to assess fabric flammability. A second rating can be obtained using the Limiting Oxygen Index which is the minimum volume fraction of oxygen which, when mixed with nitrogen, sustains burning of the fabric. Means of measuring radiant and convective heat transfer are discussed as are radiant heat sources, flame impingement heat sources, radiant/convective heat sources, heat sensors, the prediction of skin burn injuries from test measurements, evaluation of heat transfer through protective fabrics, molten metal splash tests, and performance requirements for protective fabrics. Part of the problem with the studies reviewed was that too few of the fabrics tested have been tested under conditions which make the results of the tests comparable. The authors stress the importance of establishing realistic performance criteria for the evaluation of fabrics for safety clothing.
