<p><P>PROBLEM TO BE SOLVED: To provide a washing method for satisfying both detergency and softening effect when a fiber product is softened in a first rinsing step. <P>SOLUTION: The washing method for a fiber product includes the following step 1 which is carried out at least once and the following step 2 which is carried out after the final step 1. The step 1 is a step for washing a fiber product in a washing liquid containing a detergent containing a specific nonionic surfactant and an anionic surfactant in a specific mass ratio. The step 2 is a step that separates the washing liquid from the fiber product after completion of the step 1 and treats the fiber product with rinsing water containing a fiber product treatment agent containing a specific softening agent, a nonionic surfactant and a component selected from 12-22C fatty acids. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
