The viscosity of amino silicone oil is directly proportional to the molecular weight. The larger the molecular weight, the better the film-forming properties of amino silicone oil on the fabric and the softer the hand feel. However, because the amino silicone oil molecules are cross-linked when the fabric is dried, the initial molecular weight of the amino silicone oil is different from the molecular weight of the final film formed on the fabric. If the viscosity is too low, the treated fabric cannot obtain sufficient smoothness, but if the viscosity is too high, it is difficult to make a microemulsion. The viscosity of amino silicone oil used as fabric finishing agent is generally about 1000mPa·s, and some are as high as 10000mPa·s.
