Synthesis,Characterization and Application of Polyurethane Modifying Polyether Block Polysiloxane
In this article,a HO-terminated polyether-blockpolysiloxane intermediate (PESO) was firstly synthesized by the hydrosilylation of Si-H terminated polydimethylsiloxane with an allyl polyether,then a polyurethane modifying polyether-b-polysiloxane (TESO) was prepared by the reaction of PESO with 2,4toluene diisocyanate (TDI). Chemical structure and film-forming ability of TESO as well as its application on fabrics were characterized and investigated by IR,1H-NMR,scanning electronic microscope (SEM) and other instruments. Experimental results indicate TESO had a good compatibility with cationic/anionic resins or auxiliaries,and could form a hydrophilic,relatively smooth film on the cotton fabric. The binding rigidity of the cotton fabric treated by TESO clearly decreased from 146.5warp
