  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.
