The fluorine-containing and hydrogen-containing polysiloxane (FPHMS) was prepared by acid catalyzed ring-opening reaction from octamethylcyclotetrasiloxane (D4), 1,3,5-trimethyl-1,3,5-tri(3′,3′,3′-triflu-oropropyl)cyclotrisiloxane (D3F), tetramethylcyclotetrasiloxane (D4H) and hexamethyldisiloxane (MM). A kind of novel water-soluble fluorosilicone polymer (FSP) was synthesized by hydrosilylation of FPHMS with al yl poly-oxyethylene polyoxypropylene ether (F6) in the presence of a platinum catalyst. The chemical structure of FSP was characterized by IR. The interfacial property, foaming property, acid-resisting stability, alkali-resisting sta-bility and salt-resisting stability of FSP were mensurated, and its application was investigated in fabric finish-ing. Experimental results were showed as fol ows. The critical micelle concentration (cmc) of FSP solution was 1.0 g/L. The surface tension at cmc (γcmc) of FSP solution was 23.5 mN/m. The foaming power of 0.5% FSP (mass fraction) solution was 1.53 and foam stability after 5 min was 0.375. Stability of acid-resisting, alkali-re-sisting and salt-resisting was excellent. With the increase of FSP dosage, the softness of the cotton fiber treated by FSP was gradual y increased, but the whiteness and wettability of the cotton fiber treated by FSP were little change. And the whiteness and wettability of the cotton fiber treated by FSP were nearly the same with that of blank fabric.
