1 What is outdoor clothing

The outdoor environment is complex and changeable. In order to resist the harmful environment to the human body, protect the body heat from being lost and quickly discharge sweat produced during exercise, you should wear layered clothing when climbing, rock climbing and other outdoor sports. .

The so-called outdoor layered clothing refers to wearing clothes of different materials in outdoor sports to adapt to the effects of various weather changes in the wild on the human body, such as jackets, fleece pants, and warmth Clothes and pants, sun protection pants, quick-drying pants, etc.

1. Warmth retention: Although the warmth retention is closely related to the thickness of the fabric, outdoor sports do not allow clothing to be too heavy, so it must be warm and light to meet the special requirements of outdoor sportswear.

2. Moisture permeability: Water-proof and moisture-permeable clothing uses the surface tension characteristics of water to coat a layer of PTFE chemical coating on the fabric to enhance the surface tension of the fabric to tighten the water droplets as much as possible. It can't spread out and infiltrate the surface of the fabric, so it can't penetrate the pores in the fabric. At the same time, the coating is porous, and the water vapor in the monomolecular state can be smoothly transmitted to the surface of the fabric through the capillary channels between the fibers.

3. Waterproof: The primary function provided by outdoor clothing is waterproofing. Most traditional fabrics are coated or thinned for waterproofing. Later, fluorine-containing compounds or silicones are used as finishing agents for waterproofing. . The waterproof effect can be expressed in terms of water resistance and surface moisture resistance.

4. Breathability: A good outdoor clothing must not only be rainproof but also breathable. Its air permeability is determined by the microporous structure of the film, allowing gaseous water molecules to escape and preventing liquid water molecules from entering. Breathability is the ability of air to pass through the fabric.

5. Quick-drying: Moisture absorption and quick-drying is to quickly absorb the sweat produced by the body, drain it to the outer layer as much as possible, and volatilize as soon as possible, so that the body can keep as dry as possible.

6. Antistatic: Outdoor clothing is basically made of chemical fiber fabrics. When the outdoor environment is relatively dry, static electricity problems will occur. The clothes are easy to fluff and pilling, and are easy to be contaminated with dust and dirt. Close to the skin produces electrostatic adsorption.

7. Anti-ultraviolet property: The evaluation parameter of textile anti-ultraviolet radiation adopts the ultraviolet protection coefficient upf value, which represents the average effect of ultraviolet radiation calculated when the skin is not protected and calculated when the skin is protected by fabric The ratio of the average effect of ultraviolet radiation.

Outdoor clothing can be divided into three categories according to its function, that is, three layers from the inside to the outside, usually called inner clothing, warm clothing and outer clothing.

1. Inner layer clothing

Also known as (perspiration layer), shirts, underwear, underwear, socks, T-shirts and other clothing that stick to the skin. Basically use materials such as Supplex, Coolmax or Coldry. The special fiber structure of these materials has a strong siphon function, which can lead the sweat close to the skin to the outer layer and quickly maximize the surface to maximize the discharge of sweat The inner layer fulfills the requirement of quick-drying perspiration. Can make the wearer have a dry feeling. Perspiration-wicking underwear also has long sleeves and different thicknesses, and there are general shorts and long sanitary pants for the lower limbs.

2. Warm layer clothing

Also known as (middle layer), the main function of this layer is to isolate the human body from direct contact with the outside cold air, avoiding cold or even loss of temperature occur. For example: WINDSTOPPER has strong windproof, breathable and warm performance. This kind of product has the advantages of fast perspiration, light weight, warm and humid, and can be squeezed at will without deformation, but there is almost no warming effect after being damp. Its major shortcomings.

1. Inner layer-perspiration wicking layer

The first element: strong perspiration performance. Don't: pure cotton products. Because you will sweat a lot during outdoor sports, and pure cotton underwear will become heavier and close to the body after absorbing sweat, and it is not easy to dry, and it is easy to catch a cold, especially in winter, it may also cause frostbite.

Outdoor underwear is made of man-made fibers with strong sweat-wicking properties. This material has good water conductivity and can drain sweat to the underwear surface in time to ensure dry skin. Because of this, it has a unique quick-drying property and can be worn about four hours after hand washing.

2. Middle layer-warm layer

The first element: good thermal performance. This kind of clothing mostly uses fleece, rayon and down as raw materials. Fleece is a common outdoor clothing in spring and autumn and winter in low-cold areas. This fabric has the characteristics of light weight, non-absorbent, and quick-drying. It is an ideal warm layer clothing fabric. With the same weight of fleece and wool, fleece is slightly better in terms of warmth retention. Its disadvantage is poor wind resistance, fleece jacket with jacket outside has become a popular wearing combination for outdoor sports.

3. Outer layer-weatherproof layer

The first element: weatherproof, good air permeability. This layer of clothing is what everyone usually calls 'jackets' and 'jackets' . The jacket is usually a short windbreaker style with a windproof cap; the underarms are designed with zippers, which can be opened when the amount of exercise is large, speeding up heat dissipation and perspiration; all the seams of the underwear are treated with waterproof glue to avoid Water infiltrates from the seams; there are windproof skirts at the waist and trouser legs to improve windproof performance; trousers mostly use full side zippers to facilitate outdoor sports; three-dimensional elbows, knees and ankles Tailoring method, and do thickening and wear-resistant treatment.
