Hazard Protection with GORE-TEX Fabric Technology

GORE-TEX Fabric Technology

GORE-TEX Products allow wearers to work in ultimate comfort and durable protection by providing best-in-class material, construction and technologies. The secret of GORE-TEX Fabrics lies within its revolutionary bi-component membrane.

The GORE-TEX Membrane is the core of all GORE-TEX products. It is durably waterproof, windproof and breathable, and is permeable for water vapour. The result, water from the outside will never penetrate, cold winds cannot pass through, and perspiration can escape easily. This is why the body always stays dry and comfortable with GORE-TEX Products.

What is the GORE-TEX Membrane?

The GORE-TEX Membrane contains over 1.4 billion microscopic pores per square cm (9 billion per inch).

These pores are 20,000 times smaller than a water droplet, but 700 times larger than a water vapour molecule, which makes the GORE-TEX Membrane waterproof from the outside, while allowing perspiration to escape from the inside.

Integrated into the membrane structure is an oleophobic or oil hating substance that allows moisture vapour to pass through, but creates a physical barrier to contaminating substances. In order to meet specific needs of each use, Gore has developed different GORE-TEX Membranes and applies them as appropriate.

Productivity and Effectiveness Studies

Studies have shown that greater comfort helps concentration and thus increased effectiveness and productivity. If a worker's body temperature gets too high or too low they will be distracted which increases the risk of accidents.

An independent field study has shown absence rates decreased significantly amongst construction workers wearing GORE-TEX clothing compared with those wearing conventional workwear. On average those wearing GORE-TEX clothing took 1.5 fewer days sick leave over the six month study.

GORE-TEX Clothing Testing

Arco and Gore have worked together to build world-class functional products, and Gore has proven this with rigorous testing and data analysis. No other performance workwear is tested more relentlessly inside and out than GORE-TEX Products.

Rain Tower Test

The Gore rain tower is the most important test method to ensure that hazardwear engineered with GORE-TEX Fabrics is waterproof under even the most difficult practical conditions.

Breathability Test

The Ret test quantifies a fabric's resistance to heat loss by moisture vapour transfer: it depends on the restriction of the passage of a water vapour molecule from an area of high moisture concentration to an area of low moisture concentration. The lower the resistance to moisture vapour transfer (the Ret value), the easier sweat can evaporate from the skin and the lower the Ret value, the more breathable the textile is.

Waterproofness (Suter) Test

The Waterproofness (Suter) Test determines the water pressure resistance of waterproof materials. The pressure range is adaptable. Gore standards are of such a high level that durable waterproofness is ensured even under stress conditions.

Climate Chamber

Gore has made it a task to research the physiological interaction between person and clothing on a scientific basis, subjecting it to practical tests. For this reason, Gore carries out physiological clothing tests on a wide variety of clothing in the company's own climate chambers, and scientifically evaluates the clothing's effects on the human body and physical well-being.

Martindale Abrasion Test

To test GORE-TEX Fabrics' resistance to abrasion, the Martindale Abrasion Tester uses wool or sandpaper to rub the fabric over and over again with considerable pressure. Depending on how tough the fabric needs to be, this rubbing can continue for several hours.

Field Tests

Lab testing, while important and valuable, is only a prediction of performance. What makes or breaks protective garments and footwear is how they perform in the field. After all, machines don't wear clothes, people do. That's why Gore makes sure all fabrics stand up to real life situations. Before they are approved for use, Gore products must survive rigorous field testing, actual use in real environments.

GORE-TEX Footwear Testing

Gore hold themselves to much more demanding waterproofing standards than that of the EN ISO standard. To ensure that each piece of GORE-TEX Footwear meets their incredibly high standard, Gore have created a suite of tests designed to push footwear to it's limits.

Walking Simulator

The Gore Walking Simulator tests the waterproofness of GORE-TEX Footwear. For professional applications, mechanical feet with the test shoes take up 300,000 to 500,000 flex cycles in a water bath 5cm deep.

Centrifugal Test

The Gore Centrifugal Test determines the waterproofness of GORE-TEX Shoes without harming the quality. Not even the smallest leak can get past this test. Shoes are filled with water, the centrifuge rotates with 240 turns per minute. Any leak is quickly discovered.

Comfort Test

The Gore Whole Boot Comfort Test determines the breathability of GORE-TEX Shoes by testing the whole shoe, not only individual components. The effect of a perspiring foot in the shoe is simulated in a temperature controlled microclimate. Using moisture vapour transfer and absorption, a climatic factor is determined that represents a minimum standard of quality depending on the use of the shoe.
