According to the present invention, there are provided a fabric treatment composition capable of improving the dirt washability at the time of washing by treating a fabric, a fabric treatment method using the fabric treatment composition, and a fabric treated by the method.

In the following description, the term "stain removal performance" refers to a performance of improving the ease of dropping of stains during washing by treating a fabric.

[ Fabric treatment composition ]

The inventors of the present invention found that: when a fabric to be treated such as clothes is treated with the fabric treatment composition of the present invention containing a hydroxyalkyl cellulose (a) and having a surfactant content in a specific range with respect to the hydroxyalkyl cellulose, the performance of easily dropping stains during washing is improved. The detailed mechanism of action is not clear, but some of them can be presumed as follows.

In the present invention, the adsorption property of the hydroxyalkyl cellulose (a) to the surface of a fabric to be treated such as clothes is improved by setting the amount of the surfactant (B) within a specific range, and the uniform and appropriate hydrophilicity is imparted to the fabric by the hydroxyalkyl cellulose (a) adhering to the surface, and as a result, the performance that stains easily fall off during washing is presumably improved. Further, it is considered that: when the hydroxyalkyl cellulose (a) has a cationic group or a hydrophobic group, the adsorption form to the fabric is controlled, and the performance is improved.
