EXPERIMENTATION

experiment procedure

While maintaining the same room temperature conditions, prepare three mineral water bottles, imitate human body temperature and add 37°C hot water, and quickly place the filled water bottle into the test article. Wait 30 minutes to observe the temperature drop of the hot water to determine its thermal insulation performance. In order to test the scientificity of the data, each group of experiments was continuously tested 3 times, and then the average value of 3 times was taken as the experimental result.

From the experimental results, the warmth of the down jacket is best. The insulation performance of outerwear is mainly affected by two factors: one is the fabric of the outerwear; the other is the inner filling of the outerwear.

Down jackets and leather garments have a strong windproof function due to their compact and windproof fabrics. As for the fillers, the type and thickness are different, and the insulation performance is also different. The fill of the down jacket is fluffy and more breathable. The more air there is, the stronger the heat storage capacity is, so its thermal insulation performance is better. The woolen cloth is made of synthetic fibers such as wool and natural fibers such as polyester and viscose. The thickness of the coat is as thin as the leather coat, so the insulation performance is relatively poor.
