Why are clothes dried in the dryer soft and in the sun hard and rough?

If you own an indoor tumble dryer , you will probably find that the clothes taken out of the dryer are very soft and different from clothes that are taken to the sun. Although dried clothes will smell very pleasant from the sun, the fabric dries up and sometimes causes skin itchiness. Why did the two methods both use heat to remove water and dry things so differently? Let's go with WebTech360 to find the answer!

The difference between drying with a dryer and drying in air

First, you need to learn some of the changes in the texture of the fabric when exposed to water during the washing process. Usually, the clothes you use every day are woven from vegetable fibers, also known as cellulose, with high hygroscopic properties. When soaked in water, clothes absorb as much water as possible until saturated. This state causes the hydrogen bonds to be broken.

Clothes that dry naturally in the sun can sometimes get stiff and curl

Hydrogen bonds are bonds between polymer chains in the structure of cellulose. When this bond is broken, the polymer chains can slide over each other, benefiting the fabric for being easy to wash. However, the hydrogen bonds will not completely disappear and are regenerated when the water begins to evaporate, returning the cellulose to its original, strong, strong bond.

The problem is that the way the water evaporates will give a different final texture of the fabric. If using a dryer, clothes will have to move continuously. From there, affecting the formation of hydrogen bonds: more difficult, less firm and incomplete, so the fabric becomes softer. In contrast, drying outdoors, the clothes are in a fairly still state. This is a good condition for the hydrogen bonding system to be perfectly regenerated, making the fabric stiff and rough.

The dryer will make the clothes softer and less wrinkled

How not to "dry and curl" clothes

Using the dryer will make clothes soft, hips dry faster and save a lot of effort and time. You don't have to see clothes hanging naked or a thick clothesline. In addition, some dryers also have the function of ironing and renewing clothes so that they do not wrinkles and always keep the fragrance of fabric softener.

But many experts recommend that natural air drying is the best option to keep your clothes more durable. Natural drying will not fade clothes or lead to some risks such as tearing or wearing as much as using a dryer. And the dryer is one of the most energy consuming items.

While it is a bit uncomfortable to dry the clothes after drying them, keep the clothes more durable

To alleviate the drying of dry clothes naturally in the air, you can use vinegar and use less bleach. Because bleach is one of the causes of fabric stiffening. Using vinegar will help dissolve bleach and act as a natural fabric softener, making the fabric softer. Do not worry too much about the smell of vinegar on clothes, because after drying the smell of vinegar will disappear.

The habit of rinsing clothes before drying is also very beneficial, because this continuous movement is like the movement in a dryer, allowing soft clothes to dry with air. Besides disease, windy days are very favorable conditions for the natural way of drying clothes.
