Wearing knee guards in summer has become a commonplace. Office workers use them against the cold air-conditioning and people with joint problems also use knee guards when they take care of their joints in summer... According to a survey report, 13.3% of white collars said that their office environment was too cold and the temperature of the air conditioner was too low, especially when they enter an air-conditioned room from a hot outdoor environment full of sweat, they feel as if they have fallen into an ice pit. This huge temperature difference instantly produced is extremely harmful to the human body. Many people with uncomfortable joints feel pain in their knees when they enter an air-conditioned room, and the reason lies here.
So how to choose a knee guard for summer use? Before answering this question, let's first take a look at what characteristics summer knee guards should at least have.
1. Breathable and sweat-wicking. This is the primary feature that summer knee guards must have. Only by being breathable and sweat-wicking can they keep the joints dry. If the inside of the knee guard becomes wet with sweat after wearing it, it will instead make people feel uncomfortable and embarrassed.
2. Thermal insulation. This is a very important feature. In summer, we inevitably have to go back and forth between a hot outdoor environment and an air-conditioned indoor environment. As mentioned earlier, when returning to a cool indoor environment from a hot outdoor environment while sweating, all the sweat on the body will suddenly turn into an icy feeling, which can easily trigger or worsen joint conditions. Thermal-insulating knee guards can buffer the temperature difference and protect the joints.
3. Thin and close-fitting. This is not difficult to understand. In summer, people wear fewer clothes. Thick knee guards will show through skirts or pants, affecting aesthetics. I guess young and fashionable women particularly value this point.
4. Warming effect in cold air environments. Many people have experienced shivering in cold air-conditioned environments. Summer knee guards not only need to be breathable and sweat-wicking but also need to have warming functions. These two seemingly contradictory features must be unified.
So, which knee guards can meet these requirements? The most common ones on the market are made of leather, wool, cotton, and blended materials. They are inexpensive but have extremely poor breathability. After sweating, the sweat accumulates inside, making them unsuitable for summer use. Another category is knee guards made of tourmaline stone and activated carbon fiber. The selling point of these material knee guards is that they have a certain self-heating function, suitable for winter use. And because they lack thermal insulation and sweat-wicking functions, they are also unsuitable for summer use.
Then, are there no knee guards suitable for summer use? In fact, there is another magical material called Tencel fiber that is becoming fashionable. Tencel fiber, also known as Temelon fiber, was first invented by a Japanese company and is now widely used in the textile clothing industry, becoming the most popular fabric material in summer. It has the following characteristics:
1) Its heat retention ability changes with the external temperature. When it's cold, its heat retention ability increases, and when it's hot, its heat retention ability decreases. This is its first amazing feature.
2) Breathable and sweat-wicking. Once the body sweats, the regulating functional fibers (MRT fiber) in Tencel fiber will automatically become three-dimensional structures that protrude, making the space between the fabric and the skin about twice as much as when it's dry, accelerating the evaporation of sweat and keeping the skin dry and comfortable. This is its second amazing feature.
3) Thermal insulation. When entering a cold indoor environment from a hot outdoor environment, the expanded space in the fibers will act as a thermal insulation layer, preventing the body from being suddenly attacked by cold air, buffering the load on the body's joints. This is its third amazing feature.
4) Aggregating negative ions. We know that a forest bath environment with a negative ion concentration of 1000-2000 is most suitable for the human body. After wearing Tencel fiber knee guards, you can gather 1000 negative ions on the surface of your body, creating a comfortable environment like a forest bath. This is its fourth amazing feature.
5) Corresponding to the above features, Tencel fiber usually does not require thickened fabric, being delicate and close-fitting, without a sense of oppression and unlikely to loosen. Combined with fashionable seamless knitting and double-sided knitting, wearing it is more comfortable and stylish.
Because of these features, Tencel fiber as a textile material suitable for all seasons has been widely used in various industries. And the summer knee guards made of Tencel fiber, due to having all the aforementioned features, are increasingly welcomed by summer users, white collars, people with joint problems, and the elderly, becoming a representative product of summer knee guards. You might as well own a pair of Tencel knee guards and comfortably get through this summer!
