Some of the most important features required for babies products are safety and comfort. In addition to that, textile products for babies require good stain release mechanism due to risks of food spill on the material on wear. Aversin KFC-I is a perfluoro alkyl acrylic copolymer that gives water- and oil-repellent effect and is safe for human, even for babies. The purpose of this study is to investigate optimum condition for stain-release finishing of polyester-rayon fabric intended for baby apron. The addition of silicon as a softener decreases stain repellency of finished product. The permanent effect of finished product is strongly influenced by the addition of dimethylol dihydroxy ethylene urea (Decaresin) as cross-linking agent. It was shown that the best result in this circumstances is obtained by the use of Aversin KFC-I at 60 g/l, DMDHEU (Decaresin) 30 g/l, and magnesium chloride 15 g/l.
