The pretreatment conditions of kapok fiber were used with different amounts of sodium oleate(NaO), a fatty acid-based anionic surfactant, and xanthan gum(XG) as a natural thickener. At this time, NaO and XG were separately or mixed treated with 0.01%, 0.1%, 1% aqueous solution at 80℃ for 30 min. Hydrophilicity through dyeing was confirmed using Sappan wood extract. Therefore, SEM observation was performed to investigate the surface change of kapok fiber according to the conditions. The surface color difference was also analyzed. Pretreated kapok fibers were made from nonwoven fabrics and the contact angles were measured to determine their hydrophilization. The surface of the fiber after pretreatment was found to be cracked when NaO and NaO were mixed with XG. The surface color was the highest in a* and K/S values after the simultaneous treatment of NaO and XG, followed by NaO pretreatment and XG pretreatment. The contact angle of kapok fiber made of nonwoven fabric was slightly lower at 300g/m2 than the fabric weight of 150g/m2. Such hydrophilized nonwoven kapok fiber are expected to be used in various fields.
