The feeling of cold comes from the loss of body heat to a lower temperature environment (the human body is at a temperature of 36ºC). If we place an insulating barrier between the skin and the colder environment that surrounds it, and this barrier controls the transmission of heat to said environment, we will have found a solution to alleviate the feeling of cold that the body has.
On the contrary, one of the ways to eliminate heat that the human body possesses is through sweating and perspiration. If the thermal insulator does not allow the passage of water molecules from perspiration, this will be deposited on the skin, causing the well-known sensation of cold sweat.
In addition, we must not forget that an essential requirement in a textile garment with thermal insulation is its breathability.
The solution to avoid perspiration problems in our products is Martell Protect Thermal Insulation, a finish that allows control of body temperature and thermal insulation in sports and work protection garments.
Martell Protect Thermal Insulation is composed of a Phase Change Material (PCM) that allows the elastic to absorb energy (heat) when the temperature of the environment or body increases and is able to release it later when the temperature drops, therefore it helps to maintain a comfortable temperature for the body.
Martell Protect Thermal Insulation contains a biobased PCM obtained from renewable materials of plant origin. The aforementioned material changes from a solid to a liquid state and vice versa depending on the external temperature. The process of melting / crystallization occurs in the range of 20-30° C. The thermal resistance of the microencapsulate is excellent according to the TGA results obtained in a nitrogen atmosphere and a gradient of 10ºC / min. from 25 to 600ºC, where there is no appreciable thermal degradation up to 200ºC.
The microcapsule delivery system is used for active substances (natural extracts) composed by an outer membrane and a core. Its outer layer is made up of polymeric materials, in this case a wash-resistant silicone, and an inner core that contains the active material. The function of the membrane is to contain and protect the active material that constitutes the finish and preserves it from external agents.
The microcapsules remain solid despite the changes in the state of the material they contain inside. During fusion there is an absorption of heat and therefore a cooling; while when it solidifies, heat is released and therefore a heating is observed.
As it is encapsulated, Martell Protect Thermal Insulation is solid when washed, so it is advisable to wash clothes by hand to prolong its effects for a longer period.
