The growth, consolidation and success of a company on the market are strictly linked to innovation

NUVOLARI’S R&D PROJECT

The growth, consolidation and success of a company on the market are strictly linked to innovation

and to its ability to develop products that manage to anticipate and meet market needs, whether they are old or new or whether the time

is ripe or not for the market to welcome them immediately. Our project stems from these premises and our willingness to study a product aimed at filling markets gaps and at proposing something new.

“THE GOAT THAT BREATHES”

Our product is a goat leather for lining that enables enhanced breathability without changing the traditional look of a goat lining. The breathability is really important in leather production, but it is even more so in producing shoes because consumers are extremely conscious about foot care and comfort in terms shoe breathability (perspiration, bad smells, etc.).

FURTHER INFORMATION ABOUT BREATHABILITY

Many human activities -from work to sport and leisure- take place in weather conditions that are not always favorable and therefore require good protection from atmospheric agents such as cold, wind, rain and even ice and snow. The needs of insulation and protection from external agents are inevitably in contrast with the obvious need to allow the sweat to evaporate from the shoe. The function of sweat is to generate a cooling effect on our body, but it does not happen during secretion, but rather during the evaporation of sweat from the skin, since in the transition from the liquid to the gaseous state a lot of thermal energy is absorbed. For this reason one needs to do everything possible to ease evaporation and to try to interpose as few obstacles as possible between the surface of our skin and the air, without neglecting the need to protect our feet from the dangers of the external environment.

Traspiration: selection of materials. It is evident that transpiration plays an important role in the choice of materials used for the production of footwear: breathable materials in fact have the moisture of the human body removed more easily, thus decreasing the condensation of sweat, and consequently increasing the comfort feeling. Transpiration also allows better thermal insulation. Air is in fact a good thermal insulator but loses this property in the presence of liquid water, which instead has a high coefficient of heat exchange.

From a technical point of view , particular attention must be paid to the selection of materials used for shoe production (winter shoes in particular) . One should take into consideration the fact that some materials for their structural features create a real barrier effect. In such a case humidity is, as far as possible, absorbed by the materials to be gradually eliminated later on.

There is no doubt that an adequate construction of the upper is a crucial factor for a good production ; in the assembling stage the formation of continuous adhesive films and reinforcements fixed inside the upper may frustrate or jeopardize efforts made in the selection of materials with good transpiration features.
