The white shoes are yellow, how can they be whited!!!

Before the white shoes are dried, of course, the sneakers are in a wet state, with a few white paper towels pasted on the surface of the shoes, after the sun, generally will not be yellow, but do not expose the shoes to the sun, any shoes after the sun, have been"Dead"Finish.

Stick toilet paper on your shoes after washing them, and when they are dry, you will find that they have turned white.

The yellow color on the shoes is the glue on the shoes, and after washing the shoes, the paper is pasted, and the glue is absorbed by the paper, so the shoes turn white.

In the past, white shoes turned yellow after washing, because the bleaching process of the fabric was not good at that time, and the shoes were bleached by sulfur dioxide fumigation method at that time, so they would turn yellow after washing and drying, and now the shoes are yellow, generally because of wearing shoes and sweating, the protein in the sweat is formed by heat and solidification, which is relatively firm, you can refer to my previous one: about the treatment of white clothes.

1. Wash with chlorine-containing detergents such as Bilang and Tide, soak for more than 15 minutes, and dry in the sun after washing.

2. When washing, add 1 2 drops of pure blue ink to the water and soak evenly.

3. Go to the chemical store to buy some oxalic acid, and clean it locally for a short time (pay attention to wearing rubber gloves when washing), oxalic acid is strongly corrosive!

After the shoes are fully soaked, wrap the upper with toilet paper while it is wet, and remove the toilet paper after re-drying, the yellow color will be absorbed by the toilet paper, and the upper will return to whiteness.

Bleaching principle. 1.Strong oxidizing bleaching tremor sensitive white: Principle: Oxidizes colored substances into colorless substances.

Strong oxidizing bleaching agents such as: HCl, Ca(clo)2 (active ingredient of bleaching powder), Naclo, H2O2, Na2O2, O3.

HCOs: Strong oxidizing properties, often used for tap water disinfection (chlorine gas into the water).

Ca(clo)2: Ca(clo)2, CO2 and water produce HClo and are bleaching, which is often used for bleaching clothes and fabrics.

H2O2: H2O2 has strong oxidizing properties, and 3% hydrogen peroxide is commonly used in medical disinfection.

Na2O2: Na2O2 has strong oxidizing properties and is often used for bleaching fabrics, silk, wheat straw, etc.

O3: O3 is extremely bleaching and is often used for disinfection.

2.Reductive bleaching: Principle: Combined with organic pigments to form a colorless substance, the color will be restored after the decomposition of the new substance. If the book is left out for a long time, it will turn yellow, which is the reason.

Reducing bleaching agents such as SO2, sodium dithionite (insurance powder) and other sulfur-containing reducing agents.

SO2:SO2 bleaching magenta solution, heated back to red after fading (chemical bleaching). (Comparison: chlorine gas is introduced into the magenta solution to fade and then reheated, and the color does not return).

SO2 cannot be mixed with oxidizing bleaching agents, and the +4 valent sulfur in SO2 is reducible, and will redox reaction, all of which lose their bleaching properties.

3.Physical adsorption bleaching, can be used as decolorizing agent, deodorant, rubber hole deodorant, gas mask filter canister, etc.

Physorbent bleach such as charcoal or activated charcoal.
