In the kaleidoscope of luxurious textiles, one fabric stands out for its timeless elegance and cultural allure - Cashmere. Hailing from the majestic Himalayan region, Cashmere has woven its way into the fabric of tradition. Further, its threads echo the tales of craftsmanship and heritage. Beyond its reputation as a coveted accessory, Cashmere carries with it an air of mystique. It is indeed an artisanal enigma that captivates those who seek to understand the science behind its exceptional qualities.

Cashmere is derived from the wool of the Changthangi or Himalayan goat. This fiber is renowned for its unparalleled softness and fineness. Cashmere is more than just a luxurious fiber. It is a living testament to sustainable practices, a canvas upon which the delicate dance of craftsmanship and tradition unfolds. From the hands of skilled artisans to the modern fashion runways, Cashmere continues to rule. It weaves itself into the fabric of contemporary style, adapting to changing times while retaining its essence.

So, let’s unravel the clues of curiosity. Explore the principle of cashmere heating

From a physical point of view, there are three ways of human body heat loss: heat conduction, heat convection and heat radiation. In 2015, research by Martino Colonna and others showed that thermal convection is the main cause of heat loss in cold environments.

Therefore, to keep warm, it is necessary to reduce internal heat loss, that is, to prevent heat conduction and seal convection. The thermal conductivity of textile materials is mainly affected by the thermal conductivity. In general, the lower the thermal conductivity, the warmer the material. But in the case of a small difference in thermal conductivity, what is more important is the amount of still air stored in the fiber layer.

Cashmere fiber is composed of a scale layer and cortex layer, without the medulla layer. That is to say, cashmere is hollow, forming a large air volume and a small air permeability. The air layer formed can effectively slow down the convection between the hot air between the fibers and the cold outside air, and avoid taking away heat. Therefore, the cashmere sweater is both light and warm. , while the air layer also increases elasticity and toughness.

Moreover, the thermal conductivity of cashmere is 0.045 w / m · ℃, which is second only to down and is very warm.

In addition, humidity is another important factor affecting thermal comfort. Cashmere has strong hygroscopicity and a good perspiration effect. When worn close to the body, it can automatically adjust the temperature suitable for the skin under the changing external temperature conditions and has better thermal insulation performance.

After knowing the heating principle of cashmere, there is no need to blindly pursue thickness and weight. A thin cashmere sweater is not expensive and can trap more heat when worn close to the body. Therefore, the closer you wear it, the more temperature you will lock in. If you haven’t tried cashmere sweaters yet, you might as well give it a try, it can bring you a whole new experience.
