After washing the drying shoes, was the yellow pulp, was it packed by the essence of the feet?

Anyone with small white shoes knows that after washing the shoes, use a tissue to wrap the shoes and dry it, so that the shoes will be whiter.

An important reason for this is because the shoes will leak yellow stains during drying. If you don't use a paper towel to absorb, these yellow stuff immersed with water will stay on the upper.

The feeling of tearing off the paper towels is very cool 丨 shoeslo.in

Wait, what are these yellow things? Is it the essence of sweat?

No scalp is as disgusting! It is actually ...

First of all, don't be nauseous, these yellow things are not the essence of the feet sweat at all!

The main component of sweat is water, and also contains trace inorganic salts, lactic acid and urea. These substances do not make the shoes or clothes yellow.

Do you know what the essence of sweat is like? On a hot day, you wear a black short sleeve to run; two hours later, the wet clothes are dry again, leaving white inorganic salts that cannot be evaporated on black clothes -this is how the sweat essence looks like.

The yellow substances leaked out of small white shoes are actually the essence of the foot (also a little disgusting).

Our skin secretes sebum and protects the skin. Sebum is a mixture with very complex components, including triglycerin, waxy, horned sharkne, free fatty acids, and so on. No matter if you wear socks, these things will be touched inside the shoes, the more and more. If you save too much, without cleaning, the oil will be oxidized and then yellow.

When you wash your shoes and dry, these yellowed foot oil essences will spread out of the surface of the shoes with residual moisture ride.

There are many examples around us: there are many examples:

The neckline and armpits of the white T -shirt are easy to turn yellow;

The internal hat of the white hat is easy to turn yellow;

The pillow sleeve of the two sons always turns yellow (even a bit black) -because the sebum secretion of men's scalp is often more.

Welcome everyone to add enthusiastically in the comment area!

You ask me why I have white clothes yellow? Black clothes are yellow, and you can't see it either!

If your white shoes are always exuding yellow stains when drying and drying, except for being washing (but it seems not good for shoes), then remember not to wear shoes alone and let the socks bear all this- After all, washing socks is more convenient than shoes, and buying socks is cheaper than buying shoes.

The shoes become yellow, and the shoes also have pots

The essence of the sebum is not strong enough to make the entire pair of shoes yellow. Even if you do n’t wash it, the upper and soles of small white shoes will still be yellow. This is another yellow method.

The upper of some small white shoes is a synthetic leather. The main component is polyurethane, which is PU leather. When making shoes, the raw materials are usually made into coats and drying, and then attached to the bottom of the knit or non -woven fabric at the bottom. Finally, do some processing that improves the appearance and touch, so that it is more suitable for the upper.

In addition, this ingredient can also be poured into a sole. You can look at the labels of the shoes. Are there any words such as synthetic leather, PU skin, and polyurethane in the ingredients.

However, the ingredients in the PU skin will also be oxidized, and the result is still ... yellow, and the soles of the upper are yellow.

Synthetic leather is a common material for small and white shoes 丨 cousin who is beautiful and kind

There are also many soles made of rubber, which will also change chemical structure due to light and oxidation, and everything will be yellow.

The oxidation of shoes materials not only affects color, but also affects performance, and it becomes easy to crack and damage. In order to make the shoes durable, some antioxidants are usually added in production -a type of charge, sacrificing additives to dismiss the damage to the material to the material.

However, while the antioxidant sacrifice itself, the chemical structure will change. In the end, it was also yellow.

In the life of white shoes, there are many yellowing reasons, and there are many opportunities to turn yellow. One of my important suggestions for this is to promote small yellow shoes.

How to save Huang's little white shoes?

I know, little white shoes are beautiful, that is, versatile, you want to save it.

I want, too. When washing white mesh and canvas, when the fabrics such as fabrics helped, even if it was soaked with a laundry liquid in advance, it was difficult to clean it. So I made my own clever, soaked the small white shoes into the diluted 84 disinfection solution, soaked it, and removed it with a brush dipped with the diluted 84 disinfectant.

But what is harvested is a pair of yellowed white shoes!

Later, I understood that the main ingredients of the 84 disinfectant were oxidized and corrosive effect on the rubber soles, which would make the color of the rubber bottom yellow and change the performance.

Besides, I do n’t work carefully, and I do n’t have to get in place. Let the residual sodium hypochlorite open the rubber soles under the encouragement of light and heat.

After receiving teaching and receiving professional knowledge, I have these suggestions on saving small white shoes:

For yellow -turning upper, you can dip a little diluted 84 disinfectant, and scrub;

Use color drifting agent to deal with yellow -turned yellow upper;

You must rinse clean anyway;

Replacement of drying with yin is helpful for protecting the upper and soles.

In the end, I wish you all the small white shoes, and the blessing of the East China Sea, Shoubi Nanshan, away from yellow pollution.
