Coated cotton fabrics with flame-retardant and antibacterial properties using γ-divinyltriamine propylmethyldimethoxyl silane and ammonia phytate
摘要
In this study, coated cotton fabrics with the flame retardancy and antibacterial properties using γ-divinyltriamine propylmethyldimethoxyl silane (DTMHS) and ammonia phytate (AP) were successfully prepared. The flame retardancy, thermal stability, mechanical properties, air permeability and the antibacterial properties of coated cotton fabrics were evaluated. The results indicated that the DTMHS/AP coating was successfully deposited on the surface of cotton fabrics. The damaged length of cotton/DTMHS/AP was 5.7 cm, and the limiting oxygen index reached 31.4%. The thermogravimetric analysis revealed that the char residues of cotton/DTMHS/AP in the high-temperature range increased to 39.9%. Subsequently, burning behavior analysis showed that the peak heat release rate, total heat release, and total smoke production values of cotton/DTMHS/AP were reduced by 83.9%, 22.0%, and 98.4%, respectively. Moreover, the deposition of DTMHS/AP provided cotton fabrics with antibacterial properties, while cotton/DTMHS/AP maintained their air permeability, and enhanced the breaking force compared with cotton/AP. This study emphasizes a great potential of cotton/DTMHS/AP in enhancing the eco-friendly flame retardancy and antibacterial properties of cotton fabrics.
