Thereafter, after a dehydration treatment for 1 minute, a natural drying treatment was performed. The E value of the dried evaluation cloth was measured with a color difference meter, and ΔE was calculated from the following equation (6).
ΔE = [(L value before washing process−L value after washing process) ² + (a value before washing process−a value after washing process) ² + (b value before washing process−b after washing process) Value) ² ] ^1/2 (6)
The smaller the value of ΔE calculated from the above formula (6), the better the anti-migration property. From the average value of ΔE of 10 evaluation cloths, the anti-migration property of the liquid detergent composition for textile products was evaluated according to the following evaluation criteria. Of the following evaluation criteria, 平均 (pass) if the average value of ΔE is 34 or less, ○ (pass) if it is more than 34 and 36 or less, Δ (fail) if it is more than 36 and 40 or less, 40 If it is more than x (fail).
(Evaluation criteria)
A: The average value of ΔE is 34 or less.
：: The average value of ΔE is more than 34 and 36 or less.
Δ: The average value of ΔE is more than 36 and 40 or less.
×: The average value of ΔE is more than 40.

All of Examples 1 to 13 to which the present invention was applied were excellent in detergency, decontamination prevention, foam suppression, and dye transfer prevention.
Comparative Examples 1 and 2, which did not contain the (A1) component, were inferior in washability, anti-recontamination properties, and anti-migration properties.
Comparative Examples 3 and 4, in which the content of the component (B) was less than 3% by mass, were inferior in detergency, anti-redeposition properties, and anti-migration properties.
Comparative Example 5, in which polyethyleneimine was used instead of the component (B), was inferior in detergency, anti-redeposition property, and anti-migration property.
Comparative Example 6 containing no component (C) was inferior in foam suppressing properties.
Comparative Example 7, which contained no component (D), was inferior in detergency, defoaming property and anti-migration property.
Comparative Example 8, which did not contain the component (B), was inferior in washability, anti-redeposition properties, and anti-migration properties.
From a comparison between Example 2 and Example 10, it was found that the liquid detergent composition for textile products of the present invention exhibited good detergency even if the cleaning time was short.
