Gelanots XP

is the designation for a unique product of Toyota - non-porous hydrophilic membrane. Thanks to his skills is used for the production of textile materials for sportswear (mostly is laminated on the reverse side of the fabric). Membranes with functional sportswear generally ensures that evaporated sweat can pass through the membrane and out external moisture penetrates inside - simply put - to their sweating user "not to steam up" in the rain to wet. As an example of the traditional membrane include clothing materials known under the trademark GORE-TEX, whose principle function is basically very simple: in this membrane made ​​of polytetrafluoroethylene (PTFE) are microscopic pores that are much larger than a single molecule of water (water vapor) , but still much less than the smallest water droplet. Thus water vapor passes through the micropores, but liquid water is not.

Membrane Gelanots XP from the classical microporous membranes differ fundamentally: it is non-porous (no pores), yet its superior breathability is perfect. Its development is very fast, already reaching peak values ​​of microporous membranes and at the same time, due to its neporéznosti, not their weaknesses.

Dvouvrstvý laminát = two-layer laminate
Vodotěsnost = Waterproof
Větruvzornost = Windproof
Paropropustnost = Permeability
Líc oděvu = Revers of clothing
Pojivo = Binder
Neporézní hydrofilní membrána = Non-porous hydrophilic membrane

Parameters guarantee by the manufacturer for GELANOTS XP: permeability of at least 20,000 g H20/m2.24 pm, waterproof least 20,000 mm column of H20

Permeability

Secrets of high permeability membranes Gelanots is hidden in the molecular structure of a special polyurethane (PUR), from which it is made. Among the molecules are relatively large gaps and the forces which interact in PUR molecule and water are optimal for this function. During physical exertion man sweat vapor concentration increases under his clothing. When the molecule is evaporated sweat gets close to Gelanots membrane is pulled between molecules of polyurethane and temporarily becomes part of it. This is called the membrane is hydrophilic. Due to the higher partial pressure of saturated vapor inside the clothing and the higher temperature on the inside of the membrane is then continuously pressed into small water vapor through the membrane. It is a natural phenomenon as well as water flowing from a higher to lower place.

An interesting feature for which Gelanots is called "smart membrane". During intensive movement not only more we sweat, but body temperature grows. Due to the higher temperatures, the molecules PUR move faster, the distance between them is increasing, and the ability to transmit vapor proportionately increases.

If the intensity of physical activity increases or the outside temperature decreases, evaporated sweat on the inside of the membrane begins to condense - inside the membrane becomes damp. This is the classic features breathable membranes such as PTFE ends - if condensed sweat creates continuous film, they stop breathing altogether. But not Gelanots. The hydrophilic functions can also enjoy drawing the condensed water molecules into its structure, and eliminating them on the outside of the clothing.

K mezní situaci dojde za deště, kdy je celá vnější strany oděvu pokryta vodou. Membrána PTFE má nyní zality všechny póry a její paropropustnost je nulová. V Gelanotsu parciální tlaky vodních par již také nic nezmohou, protože relativní vlhkost na obou stranách membrány je 100%. Co ale nepřestává účinkovat je rozdíl teplot. Molekuly PUR na vnitřní (teplejší) straně membrány se pohybují rychleji, vznikají tam větší mezimolekulární mezery a transport par stále (i když omezeně) probíhá.

The limit is reached during rain, when the whole out side of clothing is covered with water. PTFE membrane has now poured all its pores and permeability is zero. In Gelanots partial pressures of water vapor have also do nothing, because the relative humidity on both sides of the membrane is 100%. But what keeps performing is the temperature difference. PUR molecules on the inner (warmer) side of the membrane to move faster, there arise a larger intermolecular spacing and vapor transport still (albeit limited) progress.

If we compare the permeability of various membranes, we show it in grams of water vapor that passes through one square meter area in 24 hours. Measurements performed internationally recognized accredited testing laboratory in precisely defined by ISO. Only the results thus obtained can be regarded as an objective and authoritative. For XP GELANOTS membrane manufacturer guarantees value of at least 20,000 g / m2.24hod.

Further development is going through reducing of resistance to the passage of steam at a binder (glue) which membrane laminates to the fabric. Latest results suggest that we will see even guaranteed values ​​over 35,000 g / m2. 24.hod.

Waterproof

Degree of waterproofing membrane detects test resistance against water pressure. During this test, the prescribed way gradually increases the pressure below the membrane and the value at which the firmst dropled pushes through the membrane. The water pressure is usually converted to the height of the water column that would cause such pressure and is expressed in millimeters.

The manufacturer guarantees that GELANOTS XP keeps pressure of at least 20,000 mm water column and that figure will pay almost unchanged even after years of use.

Conventional porous membranes such as PTFE, while still achieving certain values ​​for waterproofness. Due to wear, bending, stretching or improper washing (twisting), the pores in the loaded areas expand, waterproof and gradually decreases over time can lead to soak exposed areas such as the shoulders under backpack straps, elbows and knees from inside and outside, bends at shoes, etc. The non-porous membrane structure Gelanots is therefore a great advantage here. Gelanots is compact and very flexible due to stretching during normal use there is no risk of any damage to the membrane, which would result in reduced resistance against pressure.

Elasticity

Flexibility is very important for the ability of the membrane to stretch back to its original dimension without damage, permanent deformation or loss of waterproofing. Gelanots fulfill these requirements so that it is normally laminated to elastic (stretchable) materials and knitwear or fleece.
Trouble-free lamination membrane Gelanots the stretch textile materials allows the use of flexible materials on the knees, shoulders, elbows, and other parts or complete waterproof sportswear which further increase user comfort.

Servis life

During evaluating the product life all the advantages of the membrane, which has not pores, has reflected. Common problem of conventional porous membranes PTFE is the fact that their gradually clog pores and thus worsens permeability. Salts and fats contained in the sweat, dirt and detergents can settle in the pores and clog them. Nonporous Gelanots suffers none of these.

Its flexibility and durability Gelanots preserve even at very low temperatures. In each case we tested at high altitude expeditions at temperatures down to -40 ° C. It can be observed during 4 years of the production of several thousand pieces of clothing brand products PINGUIN. After this time, only not recorded a single case of complaint, where damage to the membrane or deterioration due to the use of their properties.

Maintenance

Gelanots does not require any special cleaning processes. It can be washed in the washing machine by conventional means, designed for these types of materials (such as preparations and other NIKWAX purchased at any outdoor store) may be gently placed in the dryer. Before loading into the washer or dryer, however, inspect your pocket and remove hard and sharp objects that could damage the membrane. Zippers and velcro turn on. Use of fabric softener and dry cleaning is forbidden. Stains can be removed with benzine locally.
