- Abstract
Grafted flame retardant cotton fabrics(Cell-g-PAAMP) were prepared by graft polymerization onto pristine cotton fabrics via reversible addition-fragmentation chain transfer free radical polymerization(RAFT) method based on cellulose-based dithioester RAFT chain transfer agent(Cell-CTA), initiator of azodiisobutyronitrile and flame retardant monomer of modified adenosine monophosphate(AAMP). Fourier transform infrared spectroscopy, scanning electron microscopy and Raman spectroscopy were used to characterize chemical structure, surface morphology of Cell-g-PAAMP, morphology and graphitization degree of carbon residue of Cell-g-PAAMP after burning. The flame retardant properties and physical mechanical properties of Cell-g-PAAMP were analyzed by thermal gravimetric analyzer, limit oxygen index instrument, fabric strength tester and air permeability tester. The appearance of stretching vibration peak of p=o at 1 199cm-1 verified the preparation of Cell-g-PAAMP. The results of scanning electron microscopy and Raman spectroscopy showed a coarse surface of Cell-g-PAAMP with attached granular substance, enhanced graphitization degree, complete form and dense structure of carbon residue of Cell-g-PAAMP after burning. Compared with pure cotton fabric, Cell-g-PAAMP has a lower initial decomposition temperature, improved thermal stability and increased ultimate oxygen index, with good flame retardant effect. The permeability and breaking strength of Cell-g-PAAMP decreased, but the elongation at break increased significantly.
