Abstract
The aim of this study is to modify the hydrophilicity of Kapok fiber, which is a natural
cellulose fiber that has limited hydrophobicity. In this study, the physical properties of
Kapok fiber were investigated, including its starch content, starch and temperature variance,
and starch and NaOH content. Corn, potato, and sweet potato starches were used as
natural sizing agents and were analyzed by weight, scanning electron microscopy (SEM),
Fourier-transform infrared spectroscopy (FT-IR), dye affinity, and water dispersibility. The
SEM analysis revealed that there was almost no surface damage compared to untreated
Kapok, while the FT-IR analysis showed that the hydrophobic group was decreased for the
NaOH-treated Kapok. Potato starch treated Kapok fibers showed a significant increase in
the b* value by gardenia staining and the Kapok fibers were hydrophilized.
