Cold-resistant and warm-keeping material

Cold-resistant and warm material
# A Must-See Treasure #

 

When the cold wind of the north blows across your cheeks and the damp cold of the south penetrates your bones, a sufficiently warm garment becomes the "life-saving straw" in winter. The warmth-keeping effect of clothing depends crucially on the fabric material. With a wide variety of thermal materials available on the market, it is difficult to determine which ones are truly "anti-freezing champions"

 

 

Down: The "ceiling" of natural warmth

 

Among natural thermal insulation materials, down is undoubtedly the undisputed "top performer", especially white goose down and white duck down, which are even referred to as "breathing thermal layers". Its thermal insulation principle lies in the three-dimensional network structure formed by down fibers, which can trap a large amount of still air. Air is an excellent thermal insulation medium, effectively preventing the loss of body heat.
The warmth-keeping performance of down is primarily determined by two core indicators: down content and loftiness. The higher the down content (typically, high-quality down has a down content of over 85%), the stronger the warmth-keeping property; the higher the loftiness value (such as 600FP, 800FP), the higher the warmth-keeping efficiency of the down, resulting in better warmth-keeping effect under the same weight. High-quality down products are not only lightweight and comfortable, but also have good breathability, enabling them to easily resist the cold even in severe environments at -20℃. They are widely used in warm products such as down jackets and duvets.

 

 

Wool, as a warm material with a long history of human use, still occupies an important position today due to its excellent warmth and comfort. Wool fibers themselves have a natural crimp structure, which can trap a large amount of air. At the same time, wool has excellent moisture absorption and breathability, capable of absorbing moisture emitted by the human body and evaporating quickly, keeping the body dry and warm. It is very suitable for dealing with dry and cold weather.

 

 

Wool: a classic and durable "old partner for warmth"

 

The warmth retention performance of different varieties of wool varies significantly. Australian Merino wool, known for its fine and densely curled fibers, boasts warmth retention that far surpasses ordinary wool. Additionally, it possesses a soft and delicate texture, making it resistant to pilling. The warmth retention of wool products is also related to yarn count. The higher the count, the finer the wool fibers, the tighter the fabric, and the better the warmth retention and comfort.

 

 

Graphene: "Warmth-Retaining Black Technology" Empowered by Science and Technology

 

Graphene is a two-dimensional material composed of carbon atoms, possessing excellent thermal and electrical conductivity. When applied to thermal insulation fabrics, it can reflect the far-infrared rays emitted by the human body back to the body, achieving a "self-heating" thermal insulation effect. At the same time, it can promote blood circulation, providing a warm and comfortable experience.

 

 

thermal insulation performance

 

The advantages of graphene thermal insulation fabric lie in its high thermal insulation efficiency, fast response speed, and lightweight and breathable nature, without the heaviness of traditional thermal insulation fabrics. It is widely used in intimate apparel such as thermal underwear, socks, and gloves. In addition, graphene also possesses antibacterial and moisture-wicking properties, which can keep the interior of clothing dry and hygienic.
