The integration of agricultural by-products and natural fibers is increasingly welcomed for sustainablemanufacturing of functional textiles. This study presents a facile strategy for fabricating bio-based coloristic and ultraviolet(UV) protective cellulosic fabric pre-cationized with a chitosan derivative - hydroxypropyltrimethyl ammonium chloridechitosan (HACC) followed by simultaneous coloration and finishing using chestnut shell extract (CSE). Results revealed thatHACC significantly enhanced the CSE adsorption quantity on cellulose fibers due to the increased number of cationicbinding sites. Both cotton and viscose showed a good building up property indicating their potential for dark shade dyeing. Cotton displayed higher CSE adsorption improvement than viscose due to the higher adsorption quantity of HACC duringpre-cationization. The washing and rubbing fastness was rated as mediate to high level, which was contributed by theelectrostatic interactions between the cationized cellulose fiber and anionic CSE. Importantly, the ultraviolet protective factor(UPF) of treated cellulosic reached over 40 and well retained over 70 % after 10 repeated washings. In summary, thefabrication strategy for coloristic and functional cellulosic fabrics using two natural products introduced in this research,contributes to sustainable manufacturing of textile.
