Synthesis of Bola-type polyoxyethylene ether aminosiloxane and application in cotton fabric
摘要
Polyether amino silicone oil is frequently used as a softener in the field of textile printing and dyeing. Nevertheless, there are a number of issues with the current synthesis method, including its intricate workings and reliance on organic solvents. These issues have a negative impact on the ecological environment in addition to raising energy consumption. An original synthesis method was suggested in this study. Bola-type aminopropyl terminated polydimethylsiloxane ethoxylates (ATSEn) with different ethylene oxide (EO) addition levels were created by reacting aminopropyl polydimethylsiloxane with ethylene oxide. The experimental findings demonstrated that the particle size of ATSEn silicone emulsion first decreased and then increased as the EO segment increased. Correspondingly, there was a trend towards a decrease in the hardness of cotton fabrics treated with ATSEn, followed by an increase. Cotton treated with ATSEn is slightly less hydrophilic than commercially available block polyether amino silicone oil (TH), but has a slight advantage in the softness and elasticity of the fabric, while maintaining its coloring properties. Cotton fabrics treated with ATSEn outperformed commercially available cotton fabrics treated with TH in terms of whiteness, softness, and stiffness retention, indicating that ATSEn-treated cotton fabrics have good durability. This study opens up a new avenue for the synthesis of polyether aminosiloxane softeners.
