The textile industry uses a lot of adhesives to join materials together, and many of these adhesives use petroleum-based ingredients that are harmful to the environment. To replace petroleum-based adhesives with a more environmentally friendly option for the textile industry, this study set out to create and evaluate a hot-melt adhesive derived from cassava starch. By adding kaolin clay as a filler and tannin as a tackifier in different ratios of starch, the created adhesive was enhanced. Tannic acid to starch ratios of 2:1, 6:1, and 10:1 w/w and kaolin to starch ratios of 3:1, 5:1, and 7:1 w/w were used to investigate the effects of clay and tackifier, respectively. The adhesives's viscosity, moisture content, tensile strength, and shear strength were then measured. The presence of kaolin and tannic acid in starch-based adhesives favored a good interaction between the adhesive's ingredients. The adhesive's maximum shear strength was measured at 4.93 ± 0.11 Mpa when dry and 0.263 ± 0.21 Mpa when wet. The current data indicate that the optimal tensile strength was determined to be 3.45 ± 0.22 MPa. This result showed that hot melt adhesives based on cassava starch would be a good environmentally friendly substitute for petroleum-based adhesives, and more study in this field is necessary.
