Characterization and performance of silicone aminopolyalkykeneoxide block copolymer

With a Pt catalyst,α,ω-hydrogenpolysiloxane reacted with allyl glycidyl ether to form an intermediate,and α,ω-diepoxy-siloxane and polycondensation of this intermediate and aminopoly-alkyleneoxide yielded the silicone amino-polyalkykeneoxide block copolymer(BPEAS).Chemical structures of BPEAS were characterized using IR and 1H-NMR.Then BPEAS was applied on the cotton fabric as a finishing agent and its performance was investigated using Kawabate Evaluation System(KES) and other instruments.The results showed that the cotton fabric treated with BPEAS(viscosity of 6.7 Pa.s,amino value of 0.600 9 mmol/g) without adding emulsifier has the bending rigidity and hysteresis of the fabric decreased by 50%-60%,drape coefficient decreased by 15%,wrinkle recovery angle increased by 30°-40°,certain anti-wrinkle property soft hand,and good wettability.
