Synthesis and Application of Phosphorylated Glucose in Flame Retardancy Finishing

Abstract

An organo-phosphorus compound, namely, phosphorylated glucose (PG) was synthesized. Four chemically modified cottons, namely, carbamoylethylated, acrylamidomethylated, cellulose carbamate, and cyanoethylated cotton bearing comparable amounts of nitrogen were also prepared. The effect of incorporation of PG into a finishing formulation containing Pyrovatex CP and etherified methylolated melamine (EMM) on flame-retardancy and other properties of these modified cottons was studied when the application was carried out under different conditions. The synergistic effect of N/P ratio was thoroughly investigated through an estimation of nitrogen and phosphorus contents and their impact on flame-retardancy properties, crease recovery, tensile strength and elongation at break of the finished cotton products determined.
