Facile fabrication of antibacterial and fire-safety multifunctional cotton fabric with a triazine-phosphonate N-halamine

Cotton fabric, a cellulose-based substance, is widely utilized in our daily lives, yet it is simple to breed micro-organisms and cause fires, a problem that must be addressed immediately. The goal of this research was to create a multi-purpose cotton fabric with biocidal efficacy and flame retardacy to lift a hand against harmful micro-organism and fire hazard. To achieve this target, the typical reactivity of cyanuric chloride was utilized, and a reactive triazine-phosphonate N-halamine precursor (TDAD) was designed and deposited onto cotton fabric through traditional method. After chlorination, TDAD-modified cotton fabric presented strongly bactericidal effect against both positive and negative bacteria, all of which could be inactivated within 1 min. In addition, the multi-purpose cotton fabric demonstrated satisfactory flame retardancy with 27.5 % of LOI value and success-fully passed the flame test with self-extinguishing effect due to the joint effect of P and N elements. Furthermore, the multi-purpose coating displayed slight influence on the cytocompatibility, tensile strength and whiteness of cotton fabric. Consequently, this work offers an efficient mean to prepare multi-purpose cotton fabric with high performance.

Automated summary

The research aims to develop a multi-purpose cotton fabric with biocidal efficacy and flame retardancy. The modified cotton fabric showed strong bactericidal effect against both positive and negative bacteria within 1 minute, and successfully passed the flame test with self-extinguishing effect. Additionally, the multi-purpose coating had slight influence on the performance of cotton fabric.
