To provide a laundry method materializing little foaming in washing and preferable rinsing property, enabling sufficient washing force to be exhibited even when a rinsing step is simplified, and enabling excellent flexibility to be imparted to a textile product.SOLUTION: A laundry method of a fiber product is provided, having a washing step of bringing washing fluid into contact with the fiber product, and requiring no rinsing step after the washing step, the washing fluid comprises a component (A): a surfactant except for components (B) and (C), a component (B): a fatty acid having C12-C18 or a salt thereof, and a component (C): at least one kind of a compound selected from a group comprised of an amine compound which has in a molecule, 1-3 hydrocarbon groups having C10-26 and which may be divided by one or more kinds of groups selected from an ester group, an ether group and an amide group, a salt of the amine compound or a quaternary compound thereof, and a modified silicone, wherein density of the component (A) is 30-150 ppm with respect to total mass of the washing fluid.SELECTED DRAWING: None 【課題】洗浄時の泡立ちが少なくてすすぎ性が良好であり、すすぎ工程を簡略化した場合にも充分な洗浄力を発揮でき、かつ、優れた柔軟性を付与できる洗濯方法。【解決手段】洗浄液を繊維製品に接触させる洗浄工程を有し、かつ、前記洗浄工程の後にすすぎ工程を要しない、繊維製品の洗濯方法であって、前記洗浄液は、（Ａ）成分：下記（Ｂ）成分及び下記（Ｃ）成分を除く界面活性剤と、（Ｂ）成分：炭素数１２～１８の脂肪酸又はその塩と、（Ｃ）成分：エステル基、エーテル基及びアミド基からなる群より選ばれる１種以上の基で分断されていてもよい炭素数１０～２６の炭化水素基を分子内に１～３個有するアミン化合物、その塩及びその４級化物並びに変性シリコーンからなる群から選ばれる少なくとも１種の化合物と、を含有し、前記（Ａ）成分の濃度は、前記洗浄液の総質量に対して３０～１５０ｐｐｍである、洗濯方法。【選択図】なし
