Abstract:

In order to further expand the application field of polyamide 6(PA6) fabric, sulfanilamide was used as flame retardant agent to finish polyamide 6 fabrics by impregnation deposition at high temperature. The thermal stability, heat release ability, melt dripping performance, flame retardant property and mechanism of the treated PA6 fabric were investigated. The results showed that the treated PA6 fabric had a high LOI value of 32.2%, and the damaged length and area were reduced without dripping phenomenon, suggesting that the treated PA6 fabric reached the B1 classification with good flame retardant performance. Meanwhile, the peak heat release rate of the treated PA6 fabric decreased by 16.9%, indicating significant decrease of fire hazard. It was suggested that sulfanilamide improved the flame retardancy of PA6 fabric mainly through the gas-phase mechanism. The flame retardant treatment exerted little influence on the tensile strength and handle of the treated PA6 fabric.

Key words: polyamide fabric, sulfanilamide, flame retardant modification, anti-dripping, gas-phase mechanism
