In advertisements, it is always take the materials used in thermal underwear as a promotional stunt, such as modals, wool, bamboo charcoal, soybean fiber, and other dazzling concepts, because of these ingredients, the price doubled, but is that the case?
As a thermal undergarment factory, we know that, as a matter of fact, all textile materials, whether wool, acrylic or any other cotton, will only make a small contribution to heat preservation compared with the fabric, no matter how strong or weak their heat transfer capacity is.
Therefore, it is wrong to judge the warmth of thermal underwear by the material used. What makes thermal underwear special is its construction. Real thermal underwear, which is either laminated or padded, works the same way as a down jacket -- the more air, the more heat it holds. So the key to keeping a thermal bra warm is the fabric and structure, such as its volume and thickness, rather than the material it used.
Air has the greatest thermal resistance of any material, so when it comes to thermal underwear on the market today, the thicker and fluffier it is, the warmer it will be.
Thermal underwear with a brushed inner layer is the warmest because it is the thickest and contains the most stagnant air. A thin layer of tightly woven so-called "thermal underwear" is similar in effect to a thin spring and autumn clothing. Try it on and you'll realize the moment you put it on that you don't expect it to keep you warm.
What Is The Warmest Thermal Underwear
In conclusion, fleece-lined thermal underwear is the warmest. Fleece is usually made of polyester fiber, and the process of fleece affects the comfort and quality of thermal underwear. High quality thermal underwear fleece is soft and firm, and will not, fade color, and is not easy to produce static electricity. The surface material of thermal underwear should be natural fiber - cotton (preferably combed cotton), moisture absorption and sweat removal, comfort performance is better than chemical synthetic fiber, cost-effective is also high.
How To Choose Thermal Underwear
Look at the fabric
The quality of a thermal underwear fabric is a direct impact on the comfort of wearing the key, so when choosing thermal underwear, look at the fabric is the top priority. Watch the color and gloss of the fabric, try to avoid the poor luster, uneven color of the fabric, and you can see the number of fabric, the higher the number of the yarn, the finer the quality is better, wearing the body will be more comfortable and comfortable.
Thermal underwear has high requirements for the manufacturing of the middle insulation layer, so the high-quality thermal insulation lining is made of microfiber, which is delicate, soft and has good heat preservation. Therefore, when choosing thermal underwear, gently knead the clothes with your hands. The clothes will feel soft and smooth, no foreign body sensation, and wear performance will be higher.
As thermal underwear is a garment that comes in close contact with the skin, it is also important to check whether it has excellent resilience while ensuring comfort and closeness.
Stretch laterally or lengthwise with your hands to test resilience, or feel for yourself if you are being oppressed or restrained. Only when the clothes are comfortable and not tight can the body move more freely.
