Abstract:

In order to address high flammability and poor hydrophobic performance of cotton fabrics, the coating consisting of phenylphosphonic acid (PA) and (3-aminopropyl)triethoxysilane (APTES) were synthesized through one-pot method, in which functional cotton fabrics embraced with excellent flame retardant and hydrophobic properties, simultaneously. The thermal stability,flammability, hydrophobicity, and washing resistance of the prepared cotton fabrics were tested. Moreover, the flame-retardant mechanism was further investigated. The results showed that APTES and PA were successfully loaded on cotton fabrics. The weight loading was 15.3%. Limiting oxygen index value of functional cotton fabrics reached as high as 29.4%. The obtained fabrics extinguished immediately after removed from the ignitor. The damage length was 10.4 cm. The thermal stability was remarkably improved. Meanwhile, the release of flammable species obviously decreased. Char layer with higher graphitization degree formed during the fire. On the other hand, the water contact angle of functional cotton increased to 139°, which could not be wetted by several different liquid droplets. Based on the above results, the prepared cotton fabric exhibited excellent flame retardancy and good hydrophobicity indeed. This one-pot approach is convenient and eco-friendly.Besides, this finishing process showed few influences on feel and whiteness of cotton. The enhanced washing fastness was also achieved in this work.

Key words: cotton fabrics, flame retardant, hydrophobicity, extinguished immediately after removing the ignitor, flame-retardant mechanism
