Synthesis of a novel triazine flame retardant containing sulfur and its application to cotton fabrics

Recent Advances for Flame Retardancy of Textiles Based on Phosphorus Chemistry

“…A similar approach was adopted by Zhao and co-workers, who synthesized the flame retardant 22 (shown in Figure 14), suitable for cotton fabrics [32]. The flame retardant performances of the treated fabrics were evaluated using LOI and vertical flammability tests.…”

“…Recently, Dong et al [45] synthesized a guanidyl-and phosphorus-containing polysiloxane flame retardant (32): for this purpose, according to Figure 23 More specifically, cotton fabrics were dipped in solutions of (30) at different concentrations, in the presence of tetraethyl orthosilicate employed as a crosslinker to permanently link the polymer to the fabric substrate. The samples were then dried and cured at 160 • C. All samples were then washed before testing.…”

“…Recently, Dong et al [45] synthesized a guanidyl-and phosphorus-containing polysiloxane flame retardant (32): for this purpose, according to Figure 23 Cotton fabrics were dipped into aqueous solutions of polymer (31) at different concentrations, in the presence of a binder and a crosslinker. The treated fabrics were then squeezed, dried and then cured at 150 • C. After the treatments, the fabrics increased their LOI values; TG measurements revealed the formation of a stable char.…”

“…Recently, Dong et al [45] synthesized a guanidyl-and phosphorus-containing polysiloxane flame retardant (32): for this purpose, according to Figure 23 After washing, cotton fabrics were soaked in a bath containing the FR polymer, 2-phosphonobutane-1,2,4-tricarboxylic acid and urea at room temperature, then squeezed in laboratory scale padder, rinsed with water, dried at 80 °C and cured at 160 °C. The flame retardant performance of the treated samples was tested by cone calorimetry and thermogravimetric analyses.…”

Synthesis of a formaldehyde-free phosphorus–nitrogen flame retardant with multiple reactive groups and its application in cotton fabrics

“…It was reported that triazine-based polymers show good flame-retardant behavior by virtue of their excellent charring effect in intumescent flame retardants, which can be mainly attributed to the tertiary nitrogen in its molecule structure [5,[7][8][9][10][11][12].…”
