Definitions
- the invention relates to the field of stain removal.
- the invention may for example be used in the field of fabric care, such as garment care.
- Oxidizing agents are widely used in area of cleaning, disinfecting and bleaching. Oxidizing agents like hydrogen peroxide having formula H 2 O 2 , carbamide, sodium percarbonate, sodium perborate are also very widely added in laundry powders and detergents to remove stains on garment.
- the chemical reacting mechanism of stain removing by oxidization mechanism is illustrated by Fig. 12 .
- the stain comprises colored molecule (chromophore) defining a first product P1.
- the colored molecule is then oxidized by an oxidization agent or bleach, resulting in an intermediate product P2.
- the bleaching reaction is not very effective and requires comparatively longer time to diminish the stain color, normally 5 min to 30 min treatment time is needed depending on the stain age and stain type.
- Reaction can be accelerated by using high temperature (e.g. 70 degreeC) to reduce the treatment time significantly. But there is a risk of user's skin being injured if apply the high temperature stain removal system without taking off the stained cloth.
- high temperature e.g. 70 degreeC
- Published patent US2015225891A1 relates to a method of cleaning a substrate comprising a fabric material with optical energy, comprising applying cleaning agent to the fabric material, and applying optical energy from a source of optical energy to the fabric material having the cleaning agent applied thereto, the optical energy having one or more optical parameters selected for cleaning the fabric material.

- the coupling valve arrangement may be a part of the cartridge, or may be a part of the system to which the cartridge is adapted to cooperate.
- the invention also relates to a method of treating a stained area on a cloth by a stain removal system as described above.
- a bleach chemical refers to a group of chemicals that work through oxidation mechanisms to remove a stain. Including liquid type of bleach chemical like hydrogen peroxide and peroxy acids and solid type of bleach chemical like sodium percarbonate, sodium perborate, carbamide peroxide, etc.
- the invention is based on the principle that light activation of hydrogen peroxide H 2 O 2 helps peroxide decompose faster to form free radicals that react with organic molecules (stain colors).
- Light source can for example correspond to UV light which has a high photon energy. Blue light can also be considered. Although light source of longer wavelengths has lower photon energy which may result in less efficient photo catalysis, more heat generated by the longer wavelength light can still increase the oxidizing reaction.
- Typical spectrum for blue light is between 492nm to 455nm.
- the power of the light source is at least 500mW.
- blue light is applied as an example but other light sources like IR, white light, green light etc. should not be excluded from the same principle.
