Case Study

Zinc Carbonate Nanoneedles - A Potential Flame Retardant For Cotton Textiles

Sharma, Veerender, et al. Cellulose 25 (2018): 6191-6205.

For the first time, facilely synthesized zinc carbonate nanoneedles were integrated into cotton fabrics by padding method at around neutral pH and under alkaline treatment conditions (using sodium hydroxide) to obtain flame retardant effect on fabrics. The flame retardant properties of the treated fabrics were investigated by determining the limiting oxygen index (LOI) and vertical burning test. It was found that the fabric treated with zinc carbonate nanoneedles under alkaline conditions had an LOI value of 30 at 600°C, a specific char length of 40mm, and a char mass retention of more than 40%.
Three different formulations (A, B, C) were prepared for application on cotton fabrics. Solution A contained nano zinc carbonate (in fact, pH was neutral), and solutions B and C contained a mixture of (nano zinc carbonate → sodium hydroxide) [by adjusting pH-10] and sodium hydroxide alone, respectively. Three cotton fabrics were immersed in the corresponding solutions at 80°C for 1 hour. Thereafter, the treated fabrics were passed through a mill by maintaining a running speed of 15m/min and a mill pressure of 15kgf/cm. The padded samples were air dried and then cured at 140 °C for 3 min.
