Multifunctional ammonium polyphosphate coated cotton fabric for flame retardant, anti-wrinkle, ultraviolet protection and anti-bacterial.

The multifunctional cotton fabrics, which were expected to become one of the most promising textile materials, gained much attention in the apparel market. In this work, the simultaneous coloration and finishing processes with natural dye were carried out to prepare the multifunctional cotton fabrics. The modification process using ammonium polyphosphate (APP) imparted the cotton fabric with numerous anionic sites along with flame retardant and anti-wrinkle properties. Subsequently, the implementation of coloration with berberine was to render the cotton fabric with elegant shade and anti-bacterial, ultraviolet (UV) protection performances. The obtained results revealed that the cotton fabric treated with APP could obtain deep shade. It was found that the limited oxygen index (LOI), wrinkle recovery angle (WRA), ultraviolet protection factor (UPF) and antibacterial efficiency of treated fabric were 46.4%, 252°, 193 and 99%, respectively. More importantly, the repeated laundering showed negligible influence on the flame retardant and anti-wrinkle performances. In addition, the anti-bacterial and UV protection performance of treated cotton fabric exhibited a slight decline even after 20 cycles of washing. Finally, the washing and rubbing fastness of obtained cotton fabric were also desirable. [Display omitted] • The synergistic effect of APP and berberine imparted cotton multi-function. • The anionic treatment of cotton using APP significantly enhanced dye exhaustion. • Application of APP endowed cotton with flame retardant and anti-wrinkle properties. • UV protection and anti-bacterial properties of cotton was improved using berberine.
