Oven Drying

Thermal Chamber

The drying chamber is maintained at a standard temperature of one hundred and five degrees Celsius to evaporate water without degrading the fiber. Samples are weighed at regular intervals until the mass remains constant. This constant weight represents the dry mass of the material.

Weight Measurement

Inaccurate temperatures can lead to incomplete drying or thermal damage to synthetic fibers. If the oven is too hot, polyester or nylon fibers may melt or oxidize, altering the weight. The temperature is regulated to ensure consistent results.

Process Limit

Testing laboratories use this procedure to prepare samples for composition tests and to determine moisture regain. The dry weight is the starting point for all calculations in commercial fiber transactions. This method is used for both natural and synthetic fibers.
