The perspiration is a natural temperature control system of our body: the sweat evaporating herself removes the excess of heat that dissipates into the air. The sweat glands are distributed over the entire surface of our skin and it has one of the largest concentrations at the top of the head where they are at almost double of the amount compared to the rest of the body.
The hair wig sticks to the skin on the head causing a wet sensation principally due to the effect "plastic bag" typical products without perspiration. Until today almost all the hair wig were without valid system of transpiration.
The sweat glands located on the head produce almost 100 liters of sweat by year and their number on the skin arrive to be more than 250 on cm2. The mechanically perforated wig, can have almost 50/100 holes over the entire surface, have to be considered totally inadequate for the elimination of sweat.
It must to point out when on the skin is applied a traditional liquid adhesive, it creates an impermeable barrier to everything, including sweat. The sweat can’t be expelled by the pores, tends to remain trapped between the skin and the adhesive film and the stagnation allows the sweat, that has a stronger acid pH, to attack the adhesive causing the progressively dissolution, collapse and loss of adhesion.
The missing perspiration gets another problem: a bigger part of the sweat and sebum remain trapped under the wig, producing a drastic bacterial proliferation causing also itching, irritation, skin lesions and smell.
The membrane 3T, covered by two international patents, is clear like the water and thin like a veil from 21μ to 80μ (micron, thousands of a millimeter). This membrane sticks to the skin as thousands of microsuctions would done on a cm2 of skin and breaths because of its particular micropores structure. The membrane is composed by 3T Ionix molecules that allow it to absorb up, drain, expell the sweat and stop the entry of the water.
The micropores of the membrane 3T are smaller than the water molecule that can’t get through, but larger than the vapor molecule; the sweat is then partially absorbed by the 3T Ionix molecules and partially by the natural difference of the pressure that occurs on the skin during perspiration, opens the pores and sticks out maintaining a correct natural perspiration on the head.
