Commercial cassava starch (Manihot esculenta C.) donated by a Sao Paulo industry, Flor de Lotus Co., was used in this study. The composition was determined, in duplicate.28 The sample presented density of 1.47 g/cm3,14.86% humidity, and 93.8% starch, of which 16.02% was amylose and 0.20% of soluble total sugars. Starch contaminants were 14% ash 0.39% fiber 0.12% total nitrogen 0.11% lipids, totaling 0.76%. The starch was used without prior preparation. 

Plasma Treatment of Textile Fibers Treatment of Cotton and Synthetic Textiles and the Lotus Effect... 

Plasma-induced hydrophobization of cottonfabric in conjunction with increased specific surface area leads to an interesting and practically important effect. Water droplets are able to effectively remove dirt particles from the surface of the cotton fabric. This phenomenon is illustrated in Fig. 9-29 for the case of HMDSO-plasma-treated cotton fabric (Hocker, 2002) and is usually referred to as the Lotus effect. Thus, the highly hydrophobic plasma-treated surface of cotton with specific plasma-modified surface topography is extremely dust- and dirt-repellant in contact with water. As an important consequence, the plasma-treated surface also becomes repellant to bacteria and fungi. The effect is relevant not only to cotton fiber but to some other materials as well.
