Between [problem] deep layer 12 and surface 13, to form a critical layer 14 to the deep layers of the pile fibers 12a and the same color of the pile fiber 12b and the surface layer of the pile fibers 13a and the same color of the pile fibers 13b are mixed, pile layer color get gently change the pile fabric to the depth from the surface layer of. Shown by subtracting from "1" to the pile fiber total volume ratio, shown as a quotient ( ) divided by A product of the pile layer weight per unit area by multiplying the fiber specific gravity and pile length Q and pile layer unit area S pile layer in the total void volume ratio ( ) is the first liquor 20 is applied to the pile surface of the following pile fabric 95% by volume in the 90 volume percent or more, and then, on top of the second dye liquor 30 to the coated surface coated, then without performing heat color development process, a second dye liquor 30 was applied over the coated surface of the first liquor, the second liquor 30 is penetrated from the pile surface to a depth J of less than 7 mm, heating coloring treatment to dye in different colors the pile layer in with a color surface 13 of the first dye liquor and color depth 12 of the second dye liquor. .FIELD 1
