Automatic Down Filling Tester: Precision Measurement for Down & Feather Quality

The Automatic Down Filling Tester is an indispensable instrument for accurately determining the loftiness index, a critical indicator of feather and down quality. Loftiness directly reflects the internal quality of down and feathers in terms of their elasticity and thermal insulation properties. Furthermore, it indirectly reveals the degree of dispersion of the various components within the down and feather blend. As loftiness is directly correlated with the amount of trapped static air (an excellent thermal insulator), there exists a strong linear relationship between down loftiness and the thermal insulation performance of down products. Therefore, precise loftiness testing is a fundamental component of comprehensive down quality assessment.

Testing Principle: Quantifying Elasticity and Volume

The loftiness test measures the elasticity of down or feathers by determining the volume occupied by a specific amount of sample under a constant weight pressure, within a container of a defined caliber. This standardized measurement provides an objective and quantifiable metric for the insulating power and overall quality of down and feather materials.
