The development of leather flame retardant technology mainly lies in the research and development of special flame retardants for leather and the formulation of flame retardant tanning technology. At the same time, the corresponding flame retardant performance testing methods are improved to attach importance to the flame retardant modification of retanning agents, fatliquors and finishing agents. That is, flame retardant elements are introduced into the molecules of the retanning agent fatliquor and the finishing agent.

For example: heteronuclear multi-core modification of tanning agents. Introduce retanning agents such as core to increase the amount of tannin. Phosphorylation and halogenation modification of tannin extract, and phosphorylation modification of resin tanning agent. That is, the development of intumescent flame retardants is emphasized. Phosphorated halogenated modification of synthetic fatliquoring acrylic resins and protein-based finishing agents and synergistic modification of multiple flame retardant elements, and the development of low-smoke and low-toxicity environmental protection for leather High-efficiency flame retardants apply nanotechnology to the study of leather flame retardants. The establishment of leather flame retardant technology is the key to the development of leather flame retardant technology. Establishing a comprehensive characterization method and standard for leather flame retardant properties.

The effect of finishing operation on the flame retardancy of leather The final result of finishing operation is to form a protective film on the surface of leather, plus the addition of pigment paste and dye, whether it is a finishing agent or a coloring substance, its burning point is higher than that of leather Low, then in the case of heat, the coating agent and coloring substance burn first, and the released gas will play the function of gas phase flame retardant. Therefore, the finishing operation can improve the flame retardancy of the finished leather, but the effect of different types and coatings on the flame retardancy of the finished leather is also different. The research in this area needs further study.
