Selecting synthetic fibers and synthetic fabrics requires an analysis of dimensions, properties, structural features, and applications.
Operating Temperature — Operating temperature is the maximum temperature at which fibers can be used continuously, without the degradation of structural or other required end-use properties.
Fabric Strength — Fabric strength is the load per inch-width that a fabric can withstand before breaking.
Weight — Fabric weight is the weight per unit area of woven or non-woven fabric, textile or cloth.
Thermal Characteristics — Fibers and fabrics have unique responses in the presence of heat. Heat can hurt or help the fiber or fabric, but when used correctly, heat can help fiber soften, melt, or decompose. Heat can also give fiber the ability to heat set, function properly at elevated temperatures, and function at room temperature after exposure to high temperatures.
Thermal Conductivity is the linear heat transfer per unit area through a material for a given applied temperature gradient. Heat flux (h) = [thermal conductivity (k)] x [temperature gradient (ΔT)]
Electrical Resistivity –– Resistivity is the longitudinal electrical resistance (ohm-cm) of a uniform rod of unit length and unit cross-sectional area. Resistivity is the inverse of conductivity.
