Decolorization method and washing machine

Abstract

A decolorization method is a decolorization method of fabric using a washing machine configured to eject a washing liquid from a nozzle by a pressure at which the washing liquid is supplied from a supply source to the nozzle. The decolorization method includes spraying, to the fabric, a liquid column of the washing liquid extending from the nozzle or a droplet separated from the liquid column.

What is claimed is: 
     
         1 . A decolorization method of fabric using a washing machine configured to eject a washing liquid from a nozzle by a pressure at which the washing liquid is supplied from a supply source to the nozzle, the decolorization method comprising
 spraying, to the fabric, a liquid column of the washing liquid extending from the nozzle or a droplet separated from the liquid column.   
     
     
         2 . The decolorization method according to  claim 1 , comprising
 changing the pressure at which the washing liquid is supplied from the supply source to the nozzle.   
     
     
         3 . The decolorization method according to  claim 2 , comprising
 changing the pressure at which the washing liquid is supplied from the supply source to the nozzle according to a type of the fabric.   
     
     
         4 . A washing machine comprising:
 a nozzle configured to eject a washing liquid by a pressure at which the washing liquid is supplied from a supply source;   a pressurizing unit configured to pressurize the washing liquid between the supply source and the nozzle; and   an acquisition unit configured to acquire a type of fabric, wherein   a pressure at which the washing liquid is supplied from the supply source to the nozzle by the pressurizing unit is changed according to the type of the fabric acquired by the acquisition unit, and   a liquid column of the washing liquid extending from the nozzle or a droplet separated from the liquid column is sprayed to the fabric.
