Özet

Vacuum extraction is a technique that removes the unbound water from the fabrics by the help of air flow through the fabrics at high velocities. Air flow through textile fabrics is mainly affected by the fabric structure such as tightness, porosity and air permeability. This paper outlines the effects of the fabric structure on the vacuum drying efficiency. Thirty woven fabrics with different porosities were dried by vacuum extraction method, and it was found that the lower the porosity or the lower the air permeability, the higher the water removal effects and energy requirement.
