Abstract
For the fabrication of the “lotus-type” fibers, a combination of two major requirements, low surface energy and the magnified of the degree of roughness, should be utilized. In this research, the possible surface roughening effect of aminolysis of the polyester fibers was applied to manipulated surface topography while fluorocarbon polymer layer generates low surface energy. The results were compared with the method that created variety of surface roughness by changing the size of the nano-silica particles using the 3M water/oil repellency test, sliding (tilt) angle, microscopy (SEM), decay of hydrophobicity, self-cleaning, and tensile properties. The results indicated the usefulness of the conventional polyester aminolysis process to control surface roughness for enhancement of fabric hydrophobicity with sliding angle as low as 12°.
