Metal fiber is one of the new fiber materials in the field of high technology, while carbon fiber is a material with both strong tensile strength of carbon material and soft workability of fiber, both are very soft materials and both have electrical, thermal and mechanical advantageous properties. Heating elements are widely used in all kinds of products that need to be heated. The Heating elements are used in clothing, such as jackets, undershirts, pants, gloves, socks, shoes, etc., to give full play to the characteristics of uniform and rapid heating, far-infrared heating, bending resistance, washable, safe and stable.
Carbon fibre heaters or metal fibre composite wire heaters are only 1mm thick, light and thin, but also very soft, placed in clothes, light, breathable, soft, very comfortable to wear. Metal fibre composite wire heaters are resistant to bending and pulling, and its heaters are covered with glue and other waterproof designs, and it is built into the clothing sandwich and can be washed with water.
Far infrared rays are the most absorbable infrared rays on the surface of water and human skin (80% of water) and the heat is easily absorbed by conduction into the tissues and bloodstream and transmitted around the body. During the heating process, carbon or metal fibre composites emit large amounts of beneficial far infrared rays when heated. It promotes blood circulation, strengthens the body's immune system and is beneficial to health.
In the heating apparel, carbon fibre heaters or metal fibre composite wire heaters are supplied with energy by batteries to generate heat. The thermal conversion rate of the heater is up to 98%, with good electrical conductivity, thermal conductivity and flexibility, and is placed inside the heated clothing to generate heat quickly and save energy. Metal fibre composite wire heater is usually designed for 5V, 7.4V, 12V, the voltage is lower than the safety voltage of the human body when working, the current exceeds 2.5A automatic power off, safety protection will not produce harm to the body, efficient warmth, safe and healthy to use.
The heating pad can heat up quickly and evenly. The maximum temperature can be reached within 5 minutes of heating. The heating pad is mainly located in important locations on the body, such as the front chest, back, abdomen, waist and knee joints. The heating apparel with built-in heaters is generally set at 3 heating temperatures, which can be freely switched according to needs.
There are many different materials used for garment heaters, the main ones being resistance wire, carbon fibre heating wire, graphene, carbon nano-film and metal fibre composite wire. Among them, the most commonly used are carbon fibre heating wire and carbon fibre heating wire. Carbon fibre heating heaters and metal fibre composite wire heaters work on the same heating principle.
Principle of operation: Their working principle can be referred to as the "electric current thermal effect", which means that the collision and friction of carbon atoms is electrically triggered by Brownian motion, which in turn generates heat. Carbon fibre heaters and metal fibre composite wire heaters have good electrical and thermal conductivity. They have an electrical conductivity of up to 98% and almost no heat loss in the heat transfer process.
