The invention discloses a high-settling-resistance and high-color-depth pigment nanocapsule coating with good settling resistance, and also discloses a preparation method of the pigment nanocapsule coating, which comprises the following steps: a large amount of low-density, inert and volatile decamethylcyclopentasiloxane or octamethylcyclotetrasiloxane is added into acrylate monomers, and the organic pigment is subjected to nano-encapsulation treatment through miniemulsion polymerization to prepare the uniform and stable nano-capsule coating. The method has the advantages of green and environment-friendly preparation process, easily obtained raw materials, simple process and high pigment coating efficiency. The invention also provides a method for applying the pigment nanocapsule coating to fabric coating printing to obtain a dark color fabric with a K/S value of more than or equal to 25, wherein the air permeability retention rate of the printed fabric is more than 70%, the stiffness is increased by less than 30%, the dry and wet rubbing fastness is more than or equal to level 4, and the hand feeling subjective rating is more than or equal to level 4. |
