The present inventors have discovered that when a textile product is washed by contacting a cleaning composition containing a surfactant and a fragrance composition with water, micelles formed by the surfactant in the cleaning solution. It was discovered that the fragrance was solubilized, the fragrance composition was not adsorbed to the textile product, and the fragrance retention of the textile product after washing was reduced.
The present invention provides a method for washing textile products, and a kit for cleaning textile products, in which the textile products have excellent fragrance retention after washing.

The present invention relates to a method for washing textile products, which comprises bringing the textile product into contact with water and one or more of the following sachets A and B.
Sachet A: (a) A sachet containing detergent composition A containing a surfactant (hereinafter referred to as component (a)) Sachet B: (b) a perfume composition containing a perfume compound (hereinafter referred to as (b)) A sachet containing composition B, which contains component (referred to as component) and substantially does not contain component (a).

The present invention also relates to a kit for cleaning textile products, which includes one or more of each of the sachet A and the sachet B.

ADVANTAGE OF THE INVENTION According to this invention, when washing a textile product, the washing method of a textile product and the kit for textile product washing|cleaning which are excellent in the fragrance persistence of a textile product after washing are provided.

[How to wash textile products]
The reason why the method of washing textile products of the present invention is superior in the fragrance retention of textile products after washing is not necessarily certain, but it is presumed as follows.
When a cleaning composition containing a surfactant and a fragrance composition, a textile product, and water are brought into contact and washed, the fragrance is solubilized in micelles formed by the surfactant in the washing solution, and the textile product is washed. Fragrances are not adsorbed to the fabric, and the fragrance retention of textile products after washing is reduced.
On the other hand, in the method for washing textile products of the present invention, a sachet A containing a detergent composition A containing a surfactant, and a sachet B containing a composition B containing a fragrance composition, each containing a surfactant. and the fragrance composition are brought into contact with the textile product and water to be washed. In that case, the sachets A and B collapse due to the shear force between the fabrics of the textile product, and the detergent composition A or composition B contained therein is released, but the fragrance composition contained in the released composition B However, by first adsorbing it onto the textile product before it is solubilized into the micelles formed by the surfactant dissolved in the cleaning solution, the fragrance adsorption rate of the textile product was improved, and the effects of the present invention were obtained. It is estimated that

In the method for washing textile products of the present invention, one or more of each of sachets A and B, the textile product, and water are brought into contact with each other, and the textile product is washed.
The method of bringing one or more of each of sachets A and B, the textile product, and water into contact is preferably carried out using a washing machine.
That is, the method for washing textile products of the present invention includes using a washing machine to put one or more of each of sachets A and B, textile products, and water into a washing tub, and washing the textile products. The method is preferred.

As for the method of putting sachet A and sachet B into the washing tub, it is sufficient to put one or more of each into the washing tub, and they may be put in the same position in the washing tub, or they can be put in different positions. It's okay. Alternatively, one or more of each of the sachets A and B may be placed in the washing tub such that the sachets A and B are at different positions in the stacking direction of textile products.
Specifically, the method of putting sachets A and B is into the lower part of the textile products stacked in the washing tub (between the washing tub and the stacked textile products), the upper part (on top of the stacked textile products), and the stacked textile products. An example is a method in which the fibers are placed at any position between the fiber products. One or more of the sachet A and the sachet B may be placed in the same position at the bottom, top, or between the stacked textile products, or they may be placed in different positions. You may.
As for the order of loading, there is a method in which each sachet A and B are placed in the washing tub in advance, and then the textile products are placed in the washing tub, or a method in which the textile products are stacked in advance in the washing tub, and then each sachet A and B are stacked in the other. There is a method of placing the textile products at the bottom, top, or between the stacked textile products, or by placing each sachet A, B and the textile product alternately in the washing tub. Examples include a method in which the material is placed at the bottom, top, or between the stacked textile products.

There is no particular restriction on the method of adding water to the washing tub, and it may be before, after, or at the same time that the sachet A, the sachet B, or the textile product is put into the washing tub. From the viewpoint of further enhancing the effects of the present invention, it is preferable to add water after sachets A, B, and textile products are placed in the washing tub.

Another way to put sachets A and B is to alternately put sachets A and B and water into a washing tub stacked with textile products, and change the water level in the washing tub so that each sachet is By putting A and B between the stacked textile products located on the water surface or at the top (only when the top is located on the water surface), each sachet A and B can be placed in two or more different locations in the stacking direction of the textile products. One method is to insert it into the position.

If one or more of each of sachet A and sachet B are placed in the washing tub so that sachet A and sachet B are at different positions in the stacking direction of textile products, each sachet A and B are placed in the washing tub. From the viewpoint of uniformity of arrangement, the textile products in the washing tub are preferably 10 cm or more, more preferably 15 cm or more, even more preferably 20 cm or more, and preferably 40 cm or less, more preferably 30 cm from each other in the stacking direction of the textile products in the washing tub.

If one or more of each of sachet A and sachet B are placed in the washing tub so that sachet A and sachet B are at different positions in the stacking direction of textile products, each sachet A and B are placed in the washing tub. From the viewpoint of uniformity of placement, the textile products are placed in two or more different locations in the washing tub in the stacking direction, preferably three or more locations, more preferably four or more locations, and preferably five or less different locations. do.
