Summary:The invention discloses a method for evaluating a thermal protection duration of a fabric. A persistent thermal exposure duration for skin to reach a second-degree burn when heat storage release of a fabric is not considered and a corresponding first safe cooling duration are determined, a minimum thermal exposure duration for skin to reach a second-degree burn when heat storage release of a fabric is completely considered and a corresponding second safe cooling duration are determined, and a plurality of safe thermal exposure durations between the minimum and persistent thermal exposure durations and a plurality of third safe cooling durations are determined. The plurality of thermal exposure durations are used as x data and the plurality of cooling durations are used as y data to obtain a safe duration curve. The curve, x-axis, and y-axis further form a closed area to obtain a safe duration zone of the fabric.
