1. Introduction Cotton, spandex, polyester, and nylon are a few textile materials that can be made into goods with antibacterial and antifouling qualities [1]. Cotton is one of the natural fibers derived from plants; its main constituent is cellulose and it is used as a raw material for the textile industry. Cotton fabric has the property of easily absorbing water molecules (hygroscopic) and is biodegradable [2].

Abstract Amylose is one of the sago starch constituents which plays an important role in the processes of gelatinization, retrogradation, and the pasting process of starch texture. By separating amylose from amylopectin through a fractionation process, high-content amylose can be obtained. In this study, the process of fractionating sago starch is carried out using hot water and the addition of n-butanol dropwise with certain time variations (1, 2, 3, 4, and 5 h).
