The development of waterproof, windproof, breathable textile fabrics began long before the Gore-Tex® revolution in the 1970s. It began with natural textiles, including silk and wool in ancient civilisations and continued with cotton and linen in the nineteenth and twentieth centuries.

When was Gore-Tex invented?
1969
Invented in 1969, Gore-Tex can repel liquid water while allowing water vapor to pass through and is designed to be a lightweight, waterproof fabric for all-weather use. It is composed of stretched polytetrafluoroethylene (PTFE), which is more commonly known by the generic trademark Teflon.
Why was Gore-Tex invented?
That said, Bob Gore wasn’t attempting to improve outerwear when he created Gore-Tex. Working in his father’s Teflon factory in the late 1960s, he was simply trying to make more efficient use of the plastic by stretching it. He accidentally found that yanking Teflon filled it with air pockets.
What happened to Gore-Tex?
Gore-Tex’s main patent expired in 1997, but the company has fiercely defended its market share, writes Macquarie Research analyst Laurent Vasilescu in a report. When the boot maker Vasque, for example, introduced a product using competing eVent technology in 2002, its Gore-Tex licenses were terminated.
When was waterproof jacket made?
In 1823, Scotsman Charles MacIntosh (pictured) was granted a patent on the first ‘waterproof’ fabric. It was made by squeezing liquid rubber in between two pieces of fabric, then pressing them together.
Is Gore-Tex toxic?
Unfortunately, Gore-tex is made from the highly toxic, extremely persistent group of chemicals called perfluorochemicals (PFCs). Also used in Teflon, Stainmaster and Scotchgard, PFCs now thoroughly contaminate our air, water and bloodstreams.
Are Gore-Tex shoes toxic?
Therefore, Gore Fabrics has established goals to eliminate them from the life cycle of our consumer fabrics products. PTFE is not a PFC of Environmental Concern. PTFE is safe and environmentally sound.
What are the disadvantages of Gore-Tex?
What are the Disadvantages of Gore-Tex?
- Gore-Tex is Expensive. With publicity and prestige comes a price tag to match.
- Performance Tapers Slowly Over Time.
- Seams are Always a Weakness.
- Difficult to Care for.
- Made from Chemicals.
- Some Gore-Tex Products can be Hit or Miss.
How long does Gore-Tex last?
Gore-Tex isn’t forever
Even powerful Gore-Tex has a lifespan. For people that use their gear daily, this lifetime can range from three to five years while those who use less frequency can get close to 15 years out of their garments.
Does Gore-Tex breathe?
To directly answer your question, GoreTex doesn’t actually breathe. It is a membrane that is laminated to a synthetic material. The membrane is actually full of millions of little holes that are large enough for air to get through but too small for water to pass.
Why is Gore-Tex called Gore-Tex?
GORE-TEX was created by Bob Gore back in 1969. He discovered that when he rapidly stretched PTFE under certain conditions – it resulted in the creation of an incredibly strong, microporous material.
What is so special about Gore-Tex?
Gore-Tex is a waterproof and breathable fabric membrane that has some very special characteristics which make it the perfect material for outdoor gear. Its microporous properties repel water from the outside but let it breathe on the inside to avoid condensation and improve breathability.
Does Gore-Tex keep you warm?
GORE-TEX is an advanced fabric membrane that keeps your hands warm by keeping them dry, allowing moisture to escape, and by being a very adaptable and durable material.
What did people wear before raincoats?
rain capes
For centuries people have been making clothing to protect themselves from the rain. One of the earliest forms of rain protection clothing was designed in Ancient China and were rain capes made of straw or grass. Farmers wore the rain capes while toiling in the dirt and mud during the rainy season.
What was the first waterproof?
Motorola Defy
More recently we’ve seen a vast number of top-tier smartphones offer IP ratings as standard. However, the very first water-resistant phone was released way back in 2010. That honor went to a niche product from Motorola. Say hello to the Motorola Defy.
How did people stay dry?
More similar to Macintosh’s experiments with rubber than to clever weaving were the practical attempts made by those who worked in practical jobs to stay dry. Oilskins worn by sailors and fishermen were originally made from sailcloth coated with tar, and later from canvas coated with linseed oil and paint.
Does GORE-TEX have forever chemicals?
Gore-Tex manufacturer announces availability of new PFAS-free membrane, but still uses “forever chemicals” to make its outdoor apparel and gear.
Does GORE-TEX make your feet sweat?
Even in good conditions, Gore-Tex doesn’t allow sweat to pass through faster than you produce it, especially when you’re exerting yourself. This is especially true for your feet, which are the second sweatiest part of your body after your armpits.
Does GORE-TEX burn?
GORE-TEX PYRAD® product technology Burn protection in situations involving heat and flame exposure. GORE-TEX STRETCH product technology Improved comfort and performance. GORE-TEX THERMIUM® product technology Improved thermal comfort over an extended range of temperatures.
What does waterproof 5k mean?
The measurement of water is in millimetres, which is how the waterproof rating is determined. The higher the number, the more waterproof the jacket. A 5k or 5,000 mm rating tells us that the fabric can withstand 5,000 mm of water before it starts to leak through and makes you want to head for the hot chips at the café.
What are forever chemicals?
Dubbed “forever chemicals” because they can take thousands of years to break down, polyfluoroalkyl substances (PFAS) figure in makeup, food packaging, waterproof clothing, nonstick cookware, firefighting foams, and groundwater.
