Abstract:

In order to synchronously realize low toxicity and flame retardant properties of polyester fabrics, an environmentally friendly flame retardant, diethyl methacryloylphosphoramidate (DMPP) was synthesized through the reaction of diethyl chlorophosphate and methacrylamide. The synthesized flame retardant was grafted on PET fabrics by impregnation method. The influence of the quantity of the initiator potassium persulfate and impregnating time on the properties of the grafted fabrics were studied. The optimum finishing process was found to be as follows: the immersing time was 3 h, the initiator concentration was 3%. The tests showed that the flame retardant was grafted onto the surface of PET fabrics. After combustion, the char length of the grafted fabrics decreased from 30 cm to 7.7 cm, the limiting oxygen index increased to 28.7% and was still 27.4% after washing 10 times. The strength loss of the grafted fabrics was limited to 5% and met the apparel fabric standards.

Key words: phosphorus-nitrogen compound, flame-retardant finishing, polyester fabric, flame retardant, mechanical property
