Fig. 6 Longitudinal view of lotus fiber a Single unit (10×); b Bundle (5×, 10×, 45×)
500×, 2000× and 3500×, as shown in Fig. 7. It was observed that fiber has circular
or similar to circular shape.
Solubility test (Table 1).
Lotus fibers were subjected to various acids and alkalies in both hot and cold
conditions. It was found that fibers were dissolved in 99 % sulfuric acid in cold
condition. Hence burning and solubility test confirm and exhibit the characteristic of
cellulosic fiber.
4.2 Material Characterization of Fiber
The chemical composition of the fiber obtained by the elemental analysis was done
as per the test suggested by Turner and Doree. The values are presented in Fig. 8.
4.3 Physical Properties of Fiber
Fiber Length:
Length of the lotus fiber was recorded between 60 and 105 cm and the average
length was 80.70 cm. Fibers shorter than 15 mm tend to have insufficient length and
are to be twisted into yarn structure; the fibers longer than 150 mm tend to require
specialized spinning machinery for the conversion into yarn structure. Hence it must
have enough length to be twisted and converted into yarn structure [17].
