    Abstract

    Optimization of fabric structure for protective garment systems or glove liners requires knowledge of liquid penetration through fibrous materials also known as absorbency. To obtain reproducible absorbency results, liquid-sample contacting conditions are to be carefully monitored. A test equipment for measuring spontaneous uptake of liquids by fibrous materials has been developed which allows to control the conditions for initial contact between sample and the liquid. By continuously monitoring the approach of liquid to the sample surface and mass changes due to absorption, the first instance of liquid-sample contact and the initial uptake of liquid is simultaneously recorded on a sub-second time scale. Preliminary experimental data reported in this paper indicate that for reproducible absorbency test results initial contacting conditions should be properly established.
