Regulation method of easy dyeing for patterning four-component chenille carpet pile

A regulation method of dyeing for patterning a four-component chenille carpet pile, comprising the following steps:

• step A:
• providing four types of raw filaments α, β, γ, δ with equal linear densities and different dyeing properties;
• mixing the four types of the raw filaments α, β, γ, δ to obtain multiple types of pile filaments corresponding to different combinations of a specified number of the raw filaments α, β, γ, δ, forming a four-component chenille carpet pile filament system;
• and proceeding to step B;
• step B:
• using four preset types of dyes with the different dyeing properties and different base colors that are respectively applicable to the raw filaments α, β, γ, δ to dye the multiple types of the pile filaments corresponding to the different combinations of the specified number of the raw filaments α, β, γ, δ, thereby obtaining dyed raw filaments α, β, γ, δ in the multiple types of the pile filaments respectively;
• and proceeding to step C;
• step C:
• calculating, based on red, green, and blue (RGB) values (Rα, Gα, Bα), (Rβ, Gβ, Bβ), (Rγ, Gγ, Bγ), and (Rδ, Gδ, Bδ) of the dyed raw filaments α, β, γ, δ in the multiple types of the pile filaments corresponding to the different combinations of the specified number of the raw filaments α, β, γ, δ, RGB values of the multiple types of the pile filaments corresponding to the different combinations of the specified number of the raw filaments α, β, γ, δ, thereby calculating RGB values (Rζ, Gζ, Bζ) of a chenille carpet pile ζ corresponding to the different combinations of the specified number of the raw filaments α, β, γ, δ;
• and proceeding to step D;
• and
• step D:
• selecting combinations of four base colors with preset hue differences from preset base colors;
• dyeing, by the combinations of the four base colors, the raw filaments α, β, γ, δ in the multiple types of the pile filaments respectively according to step B to obtain multiple types of mixed-color pile filaments with the preset hue differences;
• and constructing, according to the RGB values (Rζ, Gζ, Bζ) of the chenille carpet pile ζ corresponding to the different combinations of the specified number of the raw filaments α, β, γ, δ, preset types of chenille carpet piles by tufting the multiple types of the mixed-color pile filaments with the preset hue differences;
• selecting combinations of four base colors with a hue difference of less than 60° from the preset base colors;
• dyeing, by the combinations of the four base colors, the raw filaments α, β, γ, δ in the multiple types of pile filaments respectively according to step B to obtain multiple types of mixed-color pile filaments with the hue difference of less than 60°;
• and constructing, based on the RGB values (Rζ, Gζ, Bζ) of the chenille carpet pile ζ corresponding to the different combinations of the specified number of the raw filaments α, β, γ, δ, a chenille carpet pile with a hazy color mixing effect by tufting the multiple types of mixed-color pile filaments with the hue difference of less than 60°;
• selecting combinations of four base colors with a hue difference of greater than 60° and less than 120° from the preset base colors;
• dyeing, by the combinations of the four base colors, the raw filaments α, β, γ, δ in the multiple types of pile filaments respectively according to step B to obtain multiple types of mixed-color pile filaments with the hue difference of greater than 60° and less than 120°;
• and constructing, based on the RGB values (Rζ, Gζ, Bζ) of the chenille carpet pile ζ corresponding to the different combinations of the specified number of the raw filaments α, β, γ, δ, a chenille carpet pile with a moderate color mixing effect by tufting the multiple types of mixed-color pile filaments with the hue difference of greater than 60° and less than 120°;
• and
• selecting combinations of four base colors with a hue difference of greater than 120° and less than 180° from the preset base colors, and selecting combinations of three base colors with the hue difference of greater than 120° and less than 180° from the preset base colors to cooperate with white or black to form combinations of four base colors;
• dyeing, by the combinations of the four base colors, the raw filaments α, β, γ, δ in the multiple types of pile filaments respectively according to step B to obtain multiple types of mixed-color pile filaments with the hue difference of greater than 120° and less than 180° from the preset base colors;
• and constructing, based on the RGB values (Rζ, Gζ, Bζ) of the chenille carpet pile ζ corresponding to the different combinations of the specified number of the raw filaments α, β, γ, δ, a chenille carpet pile with a clear color mixing effect by tufting the multiple types of mixed-color pile filaments with the hue difference of greater than 120° and less than 180° from the preset base colors.
