Fluorocarbon-based compound was used in this experiment to obtain water-repellent finish on nylon (Nylon 66) fabric intended for use as material for umbrella. This compound polymerizes when cured under suitable condition to form a film of low surface energy which subsequently lowers the critical surface tension of solid and hence renders it water-repellent and oil-repellent. The material was treated with finishing liquor containing: 10, 20, and 40 g/l, and then was subjected to various tests to evaluate the result. It was found that the best result was obtained by the use of fluorocarbon as much as 40 g/l. (Yanti W, Yayu R, Yullia P)
