cotton thread and real down 40X
After looking at how insulation takes place in duck down feathers and angora rabbit furs, I decided to investigate and find out why cotton clothing failed to preserve much heat. |

When viewed close up, I noticed there was one significant difference allowing heat to pass through: the thread was thin and had no pockets of air to store the emitted body heat. As seen in the picture, the thread is merely a cluster of fibers as compared to the feathers and furs which consisted of empty bubbles in the center.
