The physical and chemical properties of three sorts of organic silicone(polydimethlsiloxane,hydroxy silicone oil and amino silicone oil) were tested,and their application properties in chemical fiber of wig were compared.Appropriate organic silicone emulsion was selected.The results showed that the appropriate organic silicone emulsion should be reactive and compound.And the viscosity of polydimethlsiloxane was greater than 300Pa·s,the viscosity of amino silicone oil was about 10Pa·s,and its amino-value was about 0.4mmol/g.
