| Popis: | Poor washing durability still poses a big challenge to the practical applications of flame-retardant fabrics. Herein, a facile and eco-friendly dip-coating approach is proposed to fabricate durable flame-retardant and superhydrophobic polyester–cotton (PTCO) fabrics. Self-assembled depositions of diethylenetriamine penta(methylene-phosphonic acid) (DTPMP) and ferric ion (Fe3+) were applied on PTCO fabrics through coordination interaction. Owing to the intumescent effect of DTPMP–Fe3+ complexes, DTPMP–Fe3+-coated fabric self-extinguished in the horizontal flame testing. Polydimethylsiloxane (PDMS) was then applied on DTPMP–Fe3+ complexes to impart the flame-retardant PTCO fabrics with superhydrophobicity (water contact angle: 155.6°) and self-cleaning properties. Especially, the washing durability of DTPMP–Fe3+-coated PTCO fabrics was improved by the modification of PDMS. The DT/Fe-8BL@PDMS sample still achieved self-extinguishing in the horizontal flame testing even after 12 laundering cycles. Flame-retardant and superhydrophobic polyester–cotton fabrics are fabricated through the deposition of DTPMP–Fe3+ complexes and further modification of PDMS. |
