Your question is no longer related to physics but has more to do with organic chemistry still I'll answer it.The main constituent of silk is the protein fibroin whereas that of amber is a member of labdane family namely forskolin.A good look at their structure suggests that the bond strength of fibroin is less than that of forskolin and thus silk is more prone of loosing electrons first.Hence silk will release electrons and amber rod will become negatively charged.
