An amino-modified polysiloxane softener was prepared using chloroplatinic acid as a catalyst,polymethyl hydrogen siloxane (PMHS),and N,N-dimethylaminoacrylamide (DMAA) monomers as reaction raw materials.The best experimental scheme measured by the cross test was that reaction time 15h,reaction temperature 110℃,catalyst dosage 50×10-6(relative to the mass of the reactant),and the material ratio (n(hydrogen-containing silicone oil):n(monomer)) 1:1.2.The structure of the synthesized product was characterized by infrared spectroscopy.At the same time,the surface morphology of the linen fabric before and after amino silicone oil finishing was characterized by scanning electron microscopy (SEM).The results showed that the amino group was successfully grafted onto the PMHS side chain,and the surface of the linen fabric treated with amino silicone oil was smoother than the original linen fabric.
