An aqueous polyurethane finishing agents for fabric was synthesized with PTMEG, H12MDI, PCD2000 and DMPA as main raw materials. The influences of the ratio of -NCO/-OH,PTMEG/PCD2000, and different dosages of DMPA on the elongation at break, ensile strength and initial tack of the coating were discussed in this paper.
