The invention discloses a preparation method of
smoothing, stiffening and color deepening
silicone oil. The method comprises steps as follows: (1) synthesis of the
smoothing, stiffening and color deepening
silicone oil: the
smoothing, stiffening and color deepening
silicone oil is prepared from certain amounts of
octamethylcyclotetrasiloxane, dodecyl methyldimethoxysilane and gamma-piperazinylpropylmethyldimethoxysilane under the
catalysis of a certain quantity of catalysts at certain
polymerization temperature for a certain time; (2) emulsification of the smoothing, stiffening and color deepening
silicone oil: 10% of 2-
phenoxyethanol as a special emulsifier is added to a
silicone oil emulsifier to emulsify the smoothing, stiffening and color deepening
silicone oil, and milky-white smoothing, stiffening and color deepening silicone
oil emulsion which has the content of 40% and has slight
blue light is obtained. The smoothing, stiffening and color deepening silicone
oil emulsion realizes the color deepening effect by reducing the surface
refractive index of fabric and is an
organosilicon finishing agent, and the hand feel finishing and color deepening of the fabric are performed simultaneously, so that
energy conservation,
environmental protection, color deepening, dye saving and cost reduction are realized.
