In the cold season, a pair of plush slippers with excellent warmth performance is a close companion for us at home. Today, we will delve into the warmth effects of plush slippers in different ambient temperatures and, at the same time, combine their material characteristics to uncover the mysteries behind the warmth principles.

I. Testing Environment and Methods

To accurately test the warmth performance of plush slippers, we set up three different ambient temperatures: 5°C (simulating a relatively cold indoor environment), 10°C (a common low indoor temperature), and 15°C (a relatively comfortable temperature that still requires warmth). Several common plush slippers on the market were selected as test objects, and each pair of slippers was tested in the corresponding ambient temperature.

During the test, the tester wore the slippers and remained stationary in the corresponding environment for 30 minutes. A professional temperature measuring instrument was used to measure the temperature near the sole of the foot inside the slipper every 5 minutes and record the data. Through the analysis of these data, we can intuitively understand the ability of the slippers to maintain warmth in different environments.

II.Warmth Effects in Different Ambient TemperatureI. 

5°C Environment

In such a low-temperature environment, for some plush slippers with low plush density and thin thickness, the internal temperature dropped significantly after 10 minutes. At 30 minutes, the temperature dropped from the initial sole temperature of the human body (about 32°C) to around 25°C, with poor warmth performance. However, for those plush slippers with high plush density and a certain thickness, the temperature dropped more slowly. After 30 minutes, it could still be maintained between 28°C and 30°C, providing a continuous and relatively warm environment for the feet.

10°C Environment

In this temperature environment, the performance of plush slippers varied. The internal temperature of ordinary plush slippers dropped from 32°C to 26°C – 27°C within 30 minutes. While high-quality thick plush slippers, due to their good warmth material characteristics, the temperature only dropped to about 29°C, which could better resist the impact of low ambient temperature on the feet.

15°C Environment

In the relatively mild 15°C environment, most plush slippers could maintain a certain degree of warmth. However, even so, due to differences in plush density and thickness, the effects were still different. For slippers with high density and thickness, the internal temperature was basically stable between 30°C and 31°C, while for inferior products, the temperature dropped to 27°C – 28°C within 30 minutes.

In summary, what do you think is the key factor that determines the thermal insulation performance of slippers? Try to think about it, we will answer it in the next blog.
