A series of the polysiloxane materials modified with tertiary amino groups were synthesized. FTIR, 1HNMR were used to characterize the polysiloxane structure. The emulsions of the modified polysiloxanes are prepared. Some surface properties of the polysiloxane materials with tertiary amino groups as resins were discussed. The results show that the polysiloxane materials modified with tertiary amino side chains had good flexibility and the repellency to water. With increasing the amino value of the polysiloxanes, the flexibility of the fabrics treated with the emulsion was improved. After the samples treated with the polysiloxanes, the thermal yellowing of the polysiloxane had emerged. The whiteness of fabrics treated with the polysiloxane decreased. The K/S of the yellow fabrics treated with the modified polysiloxanes had not obvious change, the K/S of the red and blue fabrics treated with the modified polysiloxanes slightly decreased. The shapes of the reflectance spectra curves of the dyed fabrics treated without and with the modified polysiloxanes had not noticeable change.
