In the cold weather, various kinds of warm clothes around you. For people, Woolen sweaters, cashmere knitted sweaters and cashmere hoodies are the most common choices. But which one is the best for keeping warm?
The main effect on the warmth is the structure of the material. Such as wool will be warmer than ordinary material, because wool itself is curly, fluffy, contains more air, so the warmth is better. The hoodie is actually has velvet on the surface, so with fluffy surface will achieve a warm effect.
Therefore, the warmth of clothes mainly depends on whether the clothes material itself is fluffy and how much air layer can be retained. The more air layer, the better the warmth will be.
On the other hand, cashmere is relatively better than wool, because cashmere is relatively fine, so under the same weight, the cashmere is warmer because of the fluffy.
In addition to natural fluffy fibre such as cashmere and wool to keep you warm. The chemical fibre still can be processed to increase fluffiness and warmth through hollowing and curling. For example, some chemical fibers such as imitation silk cotton, feather silk cotton, as long as the fiber is fine enough, the shagginess standard, is also quite warm. Add velvet hoodie, coral velvet and so on is warm is this principle.
Sometimes hoodies and sweaters can be as warm as each other, depending on the fleece. Naturally, there are differences in warmth retention. Generally speaking, the fluffier the fabric, the warmer it is. If the fluffiness is similar, the thicker of the fabric, the warmer it is.
In addition, there is a gap between the clothing and the body, which also contains air. Because our bodies are losing heat, it gradually heats up the air, which actually acts as a thermal layer.
And in winter, it's best not to wear clothes that are too tight, leaving a little space between each piece of clothing will keep you warmer. Of course, it can not be too loose, if the air inside the clothes and the outside air convection is not warm.
In the end, I hope this post will help you when you're looking for something nice and warm clothes to wear.
