Pure weight
A laboratory metric identifies the weight of a textile sample after all moisture and foreign substances have been removed. Technicians measure oven dry clean mass by heating specimens to a constant weight in a specialized convection oven at one hundred five degrees. This figure provides the zero point baseline for calculating how much moisture a fiber holds under normal humidity.
It removes all variables.
Process integrity
Reliable results require the total removal of spinning oils and waxes before the final drying begins. When determining oven dry clean mass, the laboratory uses neutral detergents to strip the fiber down to its core natural or synthetic state. Without this step, leftover industrial residues would give a false impression of the real fiber content in the batch.
Purity is the focus.
Invoicing benchmark
Global companies utilize these absolute weights to standardize prices between regions with different climates. Derived oven dry clean mass values allow a mill in the desert to trade fairly with a mill in the tropics by applying standard regain factors to a common dry number. It serves as the foundation for the entire textile accounting world.
Numbers are universal now.
Scope limit
Measurement rules focus on solid fiber content in a controlled dry environment. While oven dry clean mass determines weight exactly, it provides no information about the tensile strength or aesthetic quality of the shipment. It assesses fundamental mass.
