In recent years, washing machines have become larger, and the value of the bath ratio expressed by the ratio of the mass of clothes (kg) to the amount of water in the washing liquid (liter), that is, the amount of water in the washing liquid (liter) / the mass of the clothes (kg) (hereinafter, this The ratio may be the bath ratio), which tends to be smaller. It is said that when the bath ratio becomes smaller, when a household washing machine is used, the mechanical force due to stirring is less likely to be transmitted to the clothes, and the washing power is lowered. The method of washing clothes of the present invention can maintain the washing power even under washing conditions having a small bath ratio. In the method for cleaning clothes of the present invention, the bath ratio is preferably 4 or more, more preferably 5 or more, in terms of detergency. The detergency can be maintained even when the bath ratio is 45 or less, further 40 or less, further 30 or less, and further 20 or less.

In the method for washing clothes of the present invention, sufficient washing power can be obtained even if the washing time is short. In terms of detergency, the cleaning time is 1 minute or more, preferably 2 minutes or more, and more preferably 3 minutes or more. From the viewpoint of economy, it is 7 minutes or less, preferably 5 minutes or less.

The method for washing clothes of the present invention is different from the method of immersing fibers in a liquid used for refining while feeding the fibers with a roller or the like, as in the method of scouring fibers, for clothes having fibers composed according to the consumer's application. As described above, the effect of the present invention can be obtained for an object on which mechanical force is not uniformly applied. Further, the cleaning method of the present invention is suitable for the rotary cleaning method. The rotary cleaning method means a cleaning method in which clothing that is not fixed to a rotating device rotates around a rotating shaft together with a cleaning liquid. The rotary washing method can be carried out by a rotary washing machine. Therefore, in the present invention, it is preferable to wash clothes using a rotary washing machine. Specific examples of the rotary washing machine include a drum type fully automatic washing machine, a pulsator type fully automatic washing machine, and an agitator type fully automatic washing machine. Each of these revolvers can be used with those commercially available for home use.

The preferred method for washing clothes of the present invention is a rotary washing method using a rotary washing machine, in that the washing speed can be improved and the washing power of spilled food can be felt more, and the clothes are washed in the rotary washing machine. This is a cleaning method in which the water used in the above, clothing, and the liquid cleaning composition for clothing of the present invention are stirred. The rotary washing machine is preferably a drum type fully automatic washing machine, a pulsator type fully automatic washing machine or an agitator type fully automatic washing machine, and a pulsator type fully automatic washing machine or an agitator type fully automatic washing machine is more preferable. A fully automatic washing machine is more preferred. In this method, the value of the bath ratio expressed by the ratio of the mass of clothes (kg) to the volume (liter) of the washing liquid in which the water used for washing and the cleaning agent composition are mixed is the mass of clothes (kg) /. The volume (liter) of the cleaning liquid is preferably 5 or more, more preferably 10 or more, and further preferably 20 or less, and the temperature of the cleaning liquid exceeds 0 ° C., preferably exceeds 3 ° C., and further 15 The temperature is preferably 1 ° C. or lower, more preferably 10 ° C. or lower, and the time from the start of stirring of the water, clothing and cleaning agent composition used for cleaning to the start of discharging the cleaning liquid from the washing machine is 1. Minutes or more is preferable, 2 minutes or more is more preferable, 3 minutes or more is more preferable, 7 minutes or less is more preferable, 6 minutes or less is more preferable, and 5 minutes or less is a more preferable washing method.

Therefore, as a method for washing clothes of the present invention, it is preferable that the temperature exceeds 0 ° C., which contains water and 0.01% by mass or more and 0.1% by mass or less of the liquid cleaning agent composition for clothes of the present invention. Is a cleaning solution above 3 ° C. and below 15 ° C., preferably below 10 ° C., and the bath ratio expressed by the ratio of the mass of the clothing to the amount of the cleaning solution (liter) is the amount of cleaning solution (liter) / clothing. Under the conditions of mass (kg) = 5 or more, preferably 10 or more, and 20 or less, the clothes are washed for 1 minute or more, preferably 2 minutes or more, more preferably 3 minutes or more, and 7 minutes or less, preferably 6 minutes or less.
