Convective heat dissipation When the cold wind penetrates the inner layer of the garment and removes warm air from the surface of the skin, it dissipates heat; therefore, the outer garment must be windproof.
Conductive heat dissipation causes heat dissipation when the body directly touches an ice-cold object, especially when the inner layer of clothing is wet. Therefore, the outer layer clothing must be able to prevent the infiltration of rainwater, and has high air permeability to prevent moisture from accumulating in the clothes. The inner clothing can actively transmit the moisture caused by sweating to the outer layer.
Three-tier outdoor clothing program
Outer layer: must be windproof, waterproof, and breathable; in particular, attention should be paid to the waterproof sealability of the hood, pockets, cuffs, zippers, and the sealing of the sutures; the dimensions are to be able to move freely after wearing the warm layer and perspiration layer As a principle. Coats with Gore-Tex fabric are the best choice.
Warming layer: Insulation effect is provided by air trapped in the pores of clothing; multilayer clothing is more regulated than single layer thick clothing, and can be increased or decreased at any time depending on the weather or the amount of activity. With Fleece brushed flannel fabrics such as Polartec and other popular, more warm than the same weight of wool, even if there is a thermal effect when wet, and fast drying is not easy to absorb water.
Perspiration wicking: Special weaving or chemical treatment makes the inner layer hydrophobic and the outer layer hydrophilic, able to drain the sweat out to keep the skin dry. Common Polypropylene, Coolmax, Thermastat and other materials have good perspiration effects.
NORTH CAPE sweat suit series
There are three series of NORTH CAPE sweatshirts from UK high technology:
Thermastat series: Hollow fiber is the secret of Thermastat's success. It can rapidly discharge moisture from the body surface and use the air layer between the fibers as insulation to reduce the convection with the outside cold air to achieve the effect of warmth. So Thermastat can make you feel comfortable even if you use it for a long time. Thermastat is best suited for winter hiking and skiing.
Rhovyl Sportswear Collection: Rhovyl's clothing is the most ingenious design. Used in combination with Rhodyl and Modal technology to achieve breathable warmth. It even has an antibacterial treatment to avoid the odors from long journeys. Do not doubt, this is the most popular basic equipment that can be worn directly or with other clothing. Rhovyl Sportswear is best suited for outdoor activities in different climates, including hiking, hiking, self-help trips and more. Coolmax Series: Coolmax's functional principle is very simple. It quickly removes the sweat from the skin and keeps the body dry. Its unique fiber shape creates fast perspiration and breathability, and its fast-drying breathability is more than twice that of normal cotton fiber!
Outdoor clothing cleaning and maintenance
1. In principle, general fabric clothing can be put into the washing machine.
2. In order to avoid the hairy surface of the clothes, you can turn the clothes upside down for cleaning.
3. Clothes like GORE-TEX should be washed with special detergent
4. GORE-TEX coat after ironing and drying with an electric iron so as to maintain its surface resistance and water repellency
5. The place where the clothes are stored should be kept dry, and the clothes should not be stored for a long time.
6. Sun exposure clothing should be enough to avoid long-term exposure to ultraviolet sunlight
Gore-Tex
Gore-Tex is a thin film of 9 billion tiny holes per square inch. These small holes are 20,000 times that of liquid water molecules, but they are seven hundred times larger than water vapor, so water droplets cannot penetrate it and water vapor can be discharged. The Gore-Tex film is adhered to the inside of nylon or other fabrics. The clothes, shoes, gloves, hats, etc., produced are wind-resistant, waterproof, and breathable, keeping the outdoor sportsman dry, warm, and comfortable. Gore-Tex original factory also provides complete and strict suture sealing and sealing technology for authorized apparel manufacturers, so that the clothes can achieve true water resistance.
Gore Tex fabrics can be divided into '2-ply' and '3-ply' categories. 'Two-layer cloth' is used to bind Gore-Tex film to the inside of nylon and other fabrics. 'Three-layer cloth' is to bind the surface cloth, Gore-Tex film and a layer of lining cloth together. 'Two-layer cloth' has the advantages of soft material, good air permeability, etc., but due to the need to add a layer of lining, bring more weight, suitable for general outdoor activities and mountaineering. 'Three layers of cloth' are more durable and less wearable and faster-drying, but the material is harder and less breathable, making it suitable for the requirements of climbing and light weight in harsh terrain.
Frequently asked questions about using Gore-Tex
Q: The Gore-Tex coat I bought two years ago does not seem to be waterproof! Whenever climbing a mountain encounters rain, the coat absorbs water, becomes heavier, and the inner clothes are soaked.
A: In order to enhance the waterproof and breathable properties, Gore-Tex coats have water repellent on the surface of the outer fabric to make the water fall into water droplets and slip off the clothes. It will not become heavier due to water absorption and keep the surface clean, allowing the sweat to be smooth and fine. Hole discharge. However, as the water is used over the years, the water repellent treatment will gradually wear out. At this time, no water droplets will form on the surface of the clothes, and the cloth will absorb some moisture. However, the Gore-Tex film under the table cloth still has a waterproof and breathable function. As for the wetness of the inner clothing, it does not come from the infiltration of rain, but because the sweat cannot be discharged smoothly.
The method for restoring the splashing effect is to wash with a medium-temperature steam iron after cleaning and drying. As long as the surface cloth itself is still treated with splashing water, it can make rain on the surface to form water droplets and restore the air permeability function. Because there is no permanent water-repellent treatment technology, after the long-term use of cleaning, the original water-repellent treatment will eventually become ineffective. At this time, it must be treated with spray-type or water-wash-type water repellent.
GTX buying guide
What is 'waterproof fabric'?
The outer garments are more or less water-repellent, but the fabrics that can be kept dry under long-term exposure to harsh environments are scarce. According to the standards set by the United States Army, a fabric must be able to withstand 25 pounds per square inch of water pressure without leaking water. That is, the fabric must be able to block the infiltration of water under high water pressure.
Test results show that the average fabric can withstand water pressures of 3 to 5 pounds per square inch, while Gore-Tex can withstand 65 pounds per square inch of water pressure without seeping water. It is known that it has excellent water resistance.
What is 'breathability'?
When your coat is not breathable, the hot and humid gases that accumulate in the activity accumulate inside. Apart from making you uncomfortable, when the temperature is low and there is wind, it is easy to catch cold when you take it off. No matter how high the waterproofness of this clothes is, it is a loss. The standards for the determination of the air permeability are different from each other. At present, it is mostly accepted that the water evaporated from one square meter of fabric surface area is measured within 24 hours. In the condition of rest, there must be evaporation between 350 and 600 grams; in the case of moderate exercise, 2000 to 3000 grams of evaporation will be needed to achieve excellent breathability.
According to the test: Gore-Tex fabric has a breathability of 2800 grams and meets the requirements of excellent air permeability. Therefore, products made from Gore-Tex fabric are waterproof, windproof and breathable, allowing you to comfortably engage in a variety of outdoor activities.
How to clean Gore-Tex coat?
Oil will reduce the waterproof and breathable effect of Gore-Tex, so keep it clean to maximize its effectiveness. Although Gore-Tex can in principle be washed with a washing machine and dried at a moderate temperature, according to the actual user experience and to avoid everyone's cognitive differences, we still recommend hand washing and drying naturally. (After all, it's not too cheap. If you've finished playing once, you're too busy with your wallet!)
The following are the basic cleaning procedures:
1. Wash with warm water and detergent at about 30°C. The dirt on the surface can be brushed with a soft brush (such as a toothbrush).
2. Rinse dirty water and replace it with water several times to make sure there is no residual detergent.
3. Dehydration at a slow speed with a dehydrator. It is best not to exceed 3 minutes.
4. Hang and dry in a ventilated place.
Gore does not recommend the use of liquid laundry detergents or waterproof/breathable clothing special lotions.
Water repellent treatment of table cloth
In order to enhance waterproof and breathability, Gore-Tex coats have water repellent on the surface fabric to make the rain water drop into the clothes, not to become heavier due to water absorption, and keep the surface clean, allowing the sweat and body heat to be discharged smoothly. . Water repellent treatment also keeps clothing dry and avoids evaporation of moisture, causing loss of body heat. However, as the water is used over the years, the water repellent treatment will gradually wear out. At this time, no water droplets will form on the surface of the clothes, and the cloth will absorb some moisture. However, the Gore-Tex film under the table cloth still has a waterproof and breathable function.
To restore the splashing effect, after washing and drying, use a medium-temperature steam iron to be careful not to iron in the same place for too long. As long as the surface cloth itself is still treated with water, it can make the rain on the surface to form water droplets.
Because there is no permanent water-repellent treatment technology, after the long-term use of cleaning, the original water-repellent treatment will eventually become ineffective. At this time, it must be treated with spray-type or water-wash-type water repellent.
Common misconceptions about Gore-Tex
The problems caused by the loss of water splashing surface are often misunderstood by users as Gore-Tex technology fails. Below are some common misunderstandings:
1. The surface fabric looks moist: this is because the water treatment process is depleted and the surface fabric absorbs moisture.
2. Feeling heavy: Same as the previous situation.
3. There is moisture in the inner layer of clothing: This is because the surface of the clothing evaporates and radiates heat, so that the temperature of the clothing is reduced, and a temperature difference is generated between the inner layer and the portion close to the body, so that the inner layer is 'wet'.
So, before you consider changing a new Gore-Tex, please confirm that it is not because of the above three reasons that you need to update. (Although it's no harm to buy one more!)
Severe leakage: If there is noticeable moisture leakage in the inner layer of clothing during the first few minutes of rain, it may be that the waterproof seal of the suture part falls off, the clothing has a hole, or the fabric itself is a problem. Please hand it over to Gore for inspection.
