For example, the alkali resistance score of the dye is calculated as a weight ratio of 80% of the chromaticity specific gravity of the washing liquid after washing, and 20% of the average staining chromaticity specific gravity, i.e., as shown in the following formula.
Alkali resistance score of dye = 0.8 x chroma of wash after wash +0.2 x average staining chroma

In one example, the lye is selected from at least one of sodium hydroxide and potassium hydroxide.
In one example, in the alkaline soaking step, the mass ratio of the alkaline solution to the detecting member 10 is 40:1 to 50:1. In the step of washing, the mass ratio of the washing liquid to the detecting member 10 is 40:1 to 50:1.
Further, in one example, in the alkaline soaking step, the mass ratio of the alkaline solution to the detecting member 10 is 42:1 to 47:1. In the step of washing, the mass ratio of the washing liquid to the detecting member 10 is 42:1 to 47:1.
In one example, the quality of the lye is the same as the quality of the water wash for each water wash.
In a specific example, in the alkaline soaking step, the mass ratio of alkaline solution to detecting member 10 is 45:1. In the step of washing, the mass ratio of the washing liquid to the detecting member 10 is 45:1.

Wherein the usage amount of a certain color yarn is the ratio of the kilometer yarn amount of the color yarn to the total kilometer yarn amount of all color yarns in the fabric to be mercerized.
In one example, the color yarn easy-to-drop staining score is calculated by a weighted average of alkali resistance scores of the dyes in the color yarn with the usage ratio of the dyes as a weight, that is, by the following formula.
Color yarn easy-to-drop staining score of a color yarn
