Synthesis and properties of silicone polyetheramine block copolymer surfactant

Synthesis and properties of silicone polyetheramine block copolymer surfactant Abstract In the presence of Pt catalyst, α,ω-hydrogenpolysiloxane reacted with allyl glycidyl ether, and an intermediate α,ω-diepoxysiloxane was formed. The epoxy cyclic-opening reaction was conducted between the intermediate and polyetheramine in isopropanol solution, the silicone polyetheramine block copolymer (BPEAS) was thus made. The chemical structures of BPEAS were characterized using IR and 1H-NMR separately. Then cotton fabric was treated with BPEAS for application purpose. The finishing effects were tested in terms of film morphology, hydrophilic ability, softness and mechanical properties. The recorded results showed that BPEAS can be used directly to treat cotton fabrics without adding any emulsifier at the viscosity of 6700 mPa·s and amino value of 0.6009 mmol/g. Bending rigidity and hysteresis of the treated fabric decreased by 53.53 % and 67.39 %, the drape coefficient dropped by 15 %, whereas the wrinkle recovery angle increased by 57.14 %. The treated cotton fabric is hydrophilic, and has a bulky soft hand, better anti-wrinkle property compared to the untreated one. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Fibers and Polymers Springer Journals

Abstract

Abstract In the presence of Pt catalyst, α,ω-hydrogenpolysiloxane reacted with allyl glycidyl ether, and an intermediate α,ω-diepoxysiloxane was formed. The epoxy cyclic-opening reaction was conducted between the intermediate and polyetheramine in isopropanol solution, the silicone polyetheramine block copolymer (BPEAS) was thus made. The chemical structures of BPEAS were characterized using IR and 1H-NMR separately. Then cotton fabric was treated with BPEAS for application purpose. The finishing effects were tested in terms of film morphology, hydrophilic ability, softness and mechanical properties. The recorded results showed that BPEAS can be used directly to treat cotton fabrics without adding any emulsifier at the viscosity of 6700 mPa·s and amino value of 0.6009 mmol/g. Bending rigidity and hysteresis of the treated fabric decreased by 53.53 % and 67.39 %, the drape coefficient dropped by 15 %, whereas the wrinkle recovery angle increased by 57.14 %. The treated cotton fabric is hydrophilic, and has a bulky soft hand, better anti-wrinkle property compared to the untreated one.
