The Mystery Of The Disappearance Of Sweat Marks

Hello, everyone today, let's talk about a common topic in summer - sweat marks on clothes.

Especially for sweaty friends, wearing a light-colored T-shirt in summer will make a little movement, and the armpit and back will be deep and shallow.
Recently, many new concept fibers have appeared in the market, such as "Anti-Sweat-Stain", "Ice Privacy Yarn", "Peep-Proof Fiber", "Sweat-Hiding Yarn", and so on.

Can't you see the sweat after wearing it?
This technology has skin core structure, nano coating and master batch dispersion control. But when taken apart, the core points to the same material, which is titanium dioxide.

How does titanium dioxide make sweat marks disappear?

In fact, the principle is not complicated. Clothes become deeper when they are wet with sweat because water replaces the air between fibers. Titanium dioxide particles are super strong light scatterers. When the amount of titanium dioxide particles is high enough, even if the clothes are wet, the scattering ability is still strong, and the difference between dry and wet vision becomes smaller.

However, the more titanium dioxide is added, the better. Excessive addition will bring two problems:

1. titanium dioxide has photocatalyst effect, which will decompose the long fiber chain.

2. the particles are unevenly distributed, and a set of needles can be discarded within a week.

So you can see that behind these high-tech names, there is actually a small white particle at work.

The charm of textile technology often lies not in the new materials, but in the extreme use of simple physical principles.
