Embodiment Construction

[0039] Hereinafter, bleach chemicals refer to the group of chemicals that work through an oxidation mechanism to remove stains. This includes liquid type bleach chemicals such as hydrogen peroxide and peroxyacids, and solid type bleach chemicals such as sodium percarbonate, sodium perborate, amine peroxide, etc.

[0040] The present invention is based on hydrogen peroxide H 2 o 2 The photoactivation of the peroxide helps the peroxide break down faster to form a free radical principle that reacts with organic molecules (stain color).

[0041] The following is the generation of photoactivated free radicals:

[0042] h 2 o 2 +hv→2OH (1)

[0043] OH·+H 2 o 2 →HO 2 ·+H 2 O (2)

[0044] HO 2 ·+H 2 o 2 →OH·+H 2 O+O 2 (3)

[0045] 2HO 2 ·→H 2 o 2 +O 2 (4)

[0046] In the above chemical reaction, "hv" corresponds to the chemical formula of photon.

[0047] The choice of light source, wavelength, intensity, and exposure time affects the efficiency of bleaching. ...

Abstract

Stain removal system (101) for treating a stained area (102) on a cloth (103), said stain removal system (101) comprises a container (104) for containing a bleach chemical, wherein the container (104)is a removable cartridge, a system (105) for carrying the bleach chemical to the stained area under a liquid form, and a light source (106) for generating light radiation (107) over the stained area(102).

Description

technical field [0001] The present invention relates to the field of stain removal. [0002] The invention may for example be used in the field of fabric care, such as garment care. Background technique [0003] Oxidizing agents are widely used in cleaning, disinfecting and bleaching applications. Oxidizing agents such as having the formula H 2 o 2 Hydrogen peroxide, urea, sodium percarbonate, and sodium perborate are also widely added to washing powder and detergent to remove stains on clothing. [0004] The chemical reaction mechanism of stain removal by oxidation mechanism Figure 12 be elaborated. [0005] The stain comprises colored molecules (chromophores) defining the first product P1. [0006] The colored molecules are then oxidized by oxidizing agents or bleaches to give intermediate P2. [0007] Water was then applied to the intermediate product to give a colorless molecule defining the final product P3. [0008] Due to H in commercial stain removal products...
