Technology of Low Formaldehyde Flame Retardant Finishing and Mechanism Research on Silk Fabric
In this paper, the organophosphorus environmentally friendly flame retardant HFPO and the nitrogenous crossing-linking agent 2D are applied to treat the silk fabric. The better condition of flame retardancy finishing is optimized through the orthogonal factor method. The flame retardant durability, free formaldehyde content, and physical and mechanical properties are also investigated and the flame-retardant mechanism is preliminarily examined. According to the research results, the carbon length of silk is 5. 7 cm, the limiting oxygen index is 37%, the free formaldehyde content is 40. 02 mg/kg, and the separate retention rates of whiteness and tensile strength are 80. 91% and 94. 06%, respectively. The P-N synergistic effect exists in the HFPO/2D system, which works in the condensed phase. They are examined via thermogravimetric analysis and scanning electronic microscopic photos of silk burning residue.
