What is Outdoor clothing
The Outdoor environment is complicated and changing. In order to resist the harm of the human body, protect the body's heat from being lost, and the sweat produced during rapid discharge of exercise. When climbing, climbing and other outdoor sports, it should be layered.
The so -called Outdoor layered dress refers to wearing different materials in outdoor sports to adapt to the impact of various weather changes in the wild on the human body, such as pants, fleece jackets, warm clothes, sunscreen pants, andSpeed dry pants and so on.
What are the characteristics of Outdoor clothing
Warmth
Although warmth is closely related to the thickness of the fabric, outdoor sports are not allowed to be too heavy, so it is necessary to keep warm and lightweight in order to meet the special requirements of Outdoor sportswear.The most common method is to add special ceramic powders such as chromium oxide, magnesium oxide, and oxide to the synthetic fibrous spinning fluid such as polyester, especially nano -grade micro ceramic powder.Thermal energy can also reflect the far -infrared rays emitted by the human body, so it has excellent thermal insulation and heat storage performance.
Wetness
waterproof and humid clothing uses the surface tension of the water, and paint a layer on the fabricPTFE(PolytetrafluoroethylenePTFEThe chemical coating of enhanced the surface tension of fabrics with the same chemical composition and different physical structures, so that the water droplets should be tightened as much as possible without scattering and infiltrating the surface of the fabric, so that the pores on the fabric are unable to.At the same time, this coating is porous, and the water vapor in the single molecular state can be smoothly distributed to the surface of the fabric through the capacity of the capillary between the fiber.
After a large amount of exercise, if you stop in the wild to rest, it is possible to form a water droplet in the inner layer of the clothes because the outside temperature and sweat cannot be scattered in the inner layer of the clothes.
"Knot" phenomenon.There is a special humidity collation process called "low -knitting dew".PU) The fabric is coated with hydrophilic nano ceramic powder. When the body is evaporated with a large amount of sweat, it can absorb too much sweat vapor, thereby avoiding the phenomenon of water vapor inside the clothes surpassed the saturated steam and transformed into water droplets.
In addition to finding a way from fiber and coating, you can also try to absorb and sweat as much as possible in the fabric structure.For example, a double -layer tissue structure is adopted, the inner layer of the close layer is hydrophobic fiber, and hydrophilic fibers are used in the outer layer, so that sweat can rely on the capillary to move from the Skin to the inner fiber, and then due to the hydrophilicity of the outer layerThe combination of fiber and water molecules is stronger than the inner hydrophobic fiber, and the water molecules are transferred from the inner layer of the fabric to the outer layer, and finally distributed to the atmosphere.
The primary function provided by Outdoor clothing is waterproof. Most traditional fabric waterproofing is coating or film. Later, waterproof treatment with fluoride or organic silicon is used.The effect of waterproofing can be represented by anti -water permeability and surface moisture.
GB/T4744-1997"Textile fabric anti -seepage measurement static water pressure test" is used to indicate the resistance encountered by the fabric through the static water pressure suffered by the fabric, that is, under the standard atmospheric conditions, the sample on the side of the sample is affected by a continuous rising water pressure.Until three water seepage, record the pressure at this time, so thatKPAorCMH2OTo indicate that the larger the value, the better the waterproof performance.
Breathable
A good Outdoor clothing must not only prevent rainproof but also breathable.Its breathable performance is determined by the microporous structure of the film, allowing gas molecules to escape, preventing liquid water molecules from entering.The breathability is the ability of air through fabrics.Under the specified test area, pressure drop and time, air flow vertical is represented by the rate of samples.Unitmm/sorm/sEssenceThe larger the value, the better its breathable performance.GB/T5453-1997The test area recommended in "Textile Facilities" is20cm2, Can also choose5cm2As well as50cm2or100cm2; Taking fabric pressure drop100Pa, Industrial fabric200PaIf the above pressure drop is not reached or not applicable, it can be selected after negotiation in various aspects50Paor200PaEssence
Stem
The hygroscopic and dryness is to quickly absorb the sweat produced by the body, try to discharge the outer layer and volatilize as soon as possible, so that the body should be kept as dry as possible.GB/T21655.1-2008"Textiles of Textiles and Smooth Drying Evaluation No.1Part: Single combination test method "uses the water absorption rate, dripping time, and core suction height of the fabric to the water -absorbing ability of the fabric to the water sweat;Speed in sweat.This standard has made specific technical requirements for knitting and knitting products for hygroscopic and drying productsGB/T21655.2-2008"Textiles of Textiles and Smooth Drying Evaluation No.2Part: The test method stipulated in the Dynamic Water Transmission Method is: Place the fabric samples horizontally. After the liquid water is in contact with its water surface, the liquid water will spread along the water surface of the fabric, and the water surface of the fabric will be transmitted to the penetration surface. At the same timeThe infiltration surface of the fabric is diffused, and the process of moisture content is a function of time.After the sample dipping surface is dripped into the test solution, the sensor that is closely in contact with the sample is used to determine the dynamic transmission of the liquid water water, and calculate a series of performance indicators to evaluate the performance of water absorption and sweating for textiles.
Anti -static
Outdoor clothing is basically made of chemical fiber fabrics. When the Outdoor environment is relatively dry, static electricity problems will occur. It shows that clothes are prone to hairs and dirt, close to the Skin to produce electrostatic adsorption.If you carry an electronic compass, altitude table,GPSSeveral electronic instruments such as navigators may also be interfered by the electrostatic of clothing and cause errors, causing serious consequences.
Comparing existing national standards and industry standards, the indicators of each method evaluation are different, and the results obtained by using different test methods are not comparable.The electricity of Outdoor clothing that can be used with good charging density method is a method for testing Outdoor clothing anti -static performance during actual wear.
UV prevention
The evaluation parameters of the textile anti -ultraviolet radiation use the ultraviolet protection factorUPFValue, it indicates that the average effect of ultraviolet radiation calculated when the Skin is not protected and the ratio of the average effect of ultraviolet radiation calculated when the Skin is protected by fabrics.GB/T18830-2009"Evaluation of Textiles Anti -UV performance" stipulates the test methods, assessment, and logo of the level of anti -sunlight ultraviolet performance of textiles.UVRadio radiation sample, collect the total spectral transmission rays, and determine the total spectral transmission ratioT(), and calculate the ultraviolet protection coefficient of the sampleupfvalue.You can use a parallel beam to illuminate the test sample, and collect all transmission light with a integral ball; you can also use a light hemisphere to illuminate the sample to collect parallel transmission light.In actual operation, the detection instrument can automatically calculate the sampleUPFValue andT().SampleUPFValue greater than50When it comes to "upf & gt; 50". According to this standard, as samplesupf & gt; 40,andT(UVA.av & lt; 5%At the same time, it can be called "anti -ultraviolet product".
