Tip 1: What is a thermofiber
To keep warm in the harsh winter, a person needs to be properly insulated. In the course are down jackets, jackets, coats. ThermoFiber is a filler for winter clothing. It is light and well-kept warm.
What is a thermofiber?
ThermoFiber is a synthetic material. It is obtained by combing the fabric and further processing it in a thermo-stove. This processing allows you to fix the fibers in the desired position. The material is used as a heater for clothes, blankets. Its advantage is the ability to keep the shape, it does not cake with time, like a normal sintepon. ThermoFiber - a modern heater of a new generation. It was designed specifically for children, because they need to make clothes warm and light. The insulation consists of siliconized fibers, they impart increased heat resistance, softness and elasticity. The fibers are hollow, which increases the thermal insulating property of the web, since air has a high thermal conductivity.It's worth taking care of your baby. Preference is given to overalls and jackets of non-toxic material. In such clothes, it is easy for children to lead a mobile lifestyle, do not be afraid to fall into a puddle or sweat heavily.
Selection of Russian manufacturers
Many Russian manufacturers usethermo-fibber for sewing winter clothes: BIBON, Lemming, QUARTET. The choice in favor of this material was not made with a simple: thermo-fiber is an environmentally friendly product. In addition, it is worth noting one more advantage of the filler - it is absolutely not allergic. This is especially important to consider if a person decided to buy himself a new mattress, blanket, sleeping bag. Proper organization of a bed is a guarantee of health.From what conditions a person rests, his psycho-emotional, physical condition depends.
Questions of buyers
Buyers often wonder: whether warm winter things on the basis of a thermal fiber are warm. According to reviews, jackets really warm even in cold winter. Do not frighten the small thickness of the product and lightness. ThermoFiber is even used in the construction of a spacesuit as a heat-retaining material. Unlike fluff, the modern heater is good for washing, deformation. After a long socks and numerous tests of moisture, frost, the thermofiber keeps all its remarkable properties. It does not slip into a ball, but absorbs 10% less water than a sintepon and a tinsulite, so its drying speed is much higher. The material has excellent ventilating properties.Tip 2: What is thermal conductivity
Thermal conductivity Is one of the concepts of thermodynamics. This is the ability of body or substance molecules in a different state (liquid, solid or gaseous) to heat exchange with each other, as well as with molecules of other bodies. Also the heat conductivity is called the quantitative evaluation of this ability, which is expressed in W / m * K.
Thermal conductivity Is the transfer of thermal energy by particlessubstances from more heated areas to less heated or to particles of another substance. The release of heat can occur as a result of combustion, friction, or nuclear reactions (nuclear fusion, nuclear fission). Heat transfer occurs in liquid, gaseous substances, solids, the temperature of which in different regions is not uniform. The thermal energy is determined by the total kinetic energy of molecules, atoms or charged particles. The process of heat conduction consists in transferring this energy between particles or contacting bodies in order to achieve thermodynamic equilibrium, temperature equalization.Thermal conductivityu is also called the quantitative characteristicheat transfer, the coefficient of thermal conductivity, which is expressed in W / (m * K) and is denoted?. The coefficient can be either positive or negative. If so, if so? > 0, then the transmission goes to the side of increasing the temperature, and when? <0 - downward. The amount of thermal energy passing through a unit of surface per unit time is called the heat flux density. The heat conduction process can be mathematically expressed by the Fourier law, which is also called the basic heat conduction law. According to this law, the density of the heat flux transmitted during thermal conductivity is proportional to the temperature gradient: Q = -? * GradT, where Q is the direction vector of the heat flux,? - the coefficient of thermal conductivity, gradT - the directing temperature vector showing the direction of the steepest increase. According to the aggregate state of the substance (solid, liquid, gaseous), the heat transfer process takes place differently, therefore, different substances have different coefficient of thermal conductivity. The coefficient of thermal conductivity of the absolute vacuum is zero. The best conductors of thermal energy are gases, the highest coefficient of thermal conductivity for helium (0.152) and hydrogen (0.1815). The worst conductors are metals, silver has the highest thermal conductivity (430). Maximum thermal conductivity of liquids? = 0.7 W / m * K is reached at a temperature of 120 °, with a further increase in temperature? decreases.Thermal conductivity Is only one type of heat exchange, there isalso convection and thermal radiation. Sometimes there is a mixed heat exchange, for example, convective heat transfer is the transfer of heat together by heat conduction and convection.
