I have long thought that the idea passed down to us by our older generation is: when buying a quilt, it seems that the weight is the same as the temperature. In fact, this is not the case. This is due to the long-term perception of a single cotton quilt. Misunderstanding. In fact, the heavier the quilt, the warmer it is. On the contrary, heavier quilts will have a certain impact on physical and mental health.

The main reason why cotton quilts are heavy is that cotton is a linear structure fiber. In fact, whether it is cotton, fiber, silk, etc., all have linear structures, so if you want to increase the bulk, you can only increase the weight, which will also make the quilt As it becomes heavier, it also becomes harder and less soft; the quilt lacks softness and will have poor breathability and poor skin-fitting feel, affecting sleep.

Where does the energy for quilt heating come from? Heat actually comes from the human body, and the quilt only plays the role of insulation, so the quilt blocks the exchange of hot and cold air. The principle is similar to that of a thermos cup. The core is the still air stored in the fluffy fibers.

Down has the only three-dimensional spherical structure among all fibers, so it has a naturally high loft, which is unmatched by other fibers.
