Popis: In order to endow cotton fabric better water repellency and flame retardancy, ferrocene formaldehyde and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) were introduced into cotton fabric through facile chemical reaction. The specific pyrolysis products of Fe@DOPO cotton tested by TG-IR was reduced obviously compare with pristine cotton. More importantly, the peak heat release rate and total heat release of the modified cotton fabric were decreased by 48.9% and 19.2%, respectively. Through the analysis of combustion mechanism, it was indicated that ferrocene and DOPO have synergistic flame retardant effect. In addition to the flame retardant, the waterproof property of Fe@DOPO cotton was also greatly improved, and the contact angle was 138°. After 12 times of washing, the limiting oxygen index (LOI) of as-prepared cotton was still 24%, indicating Fe@DOPO cotton had a good washing resistance. These excellent properties were expected to make the modified cotton fabric applied in many fields.
