Outdoor functional fabrics refer to fabrics with specific functions in the outdoor environment, such as air permeability, water resistance, wind resistance, UV resistance, etc. Due to the high requirements of outdoor activities on fabrics, how to identify high-quality outdoor functional fabrics has become a concern for many outdoor enthusiasts.
First of all, high-quality outdoor functional fabrics can be identified from the raw materials of the fabrics. The raw materials of high-quality fabrics should choose high-quality fibers, such as polyester fiber, nylon fiber, etc. These fibers have good air permeability, water resistance and wear resistance, and can be well adapted to the needs of outdoor environments. In addition, high-quality functional fabrics should also be specially treated, such as coating treatment, film composite, etc., which can improve the water resistance and wind resistance of the fabric.
Secondly, you can judge the quality of the fabric by observing its weaving. High-quality functional fabrics usually use advanced weaving processes, such as three-layer composite weaving, two-way elastic weaving and so on. These weaves can make the fabric have better strength and elasticity, but also improve the fabric breathability and comfort.
Thirdly, the quality of the fabric can be judged by testing its breathability. Air permeability is one of the important indicators of outdoor functional fabrics, because it is easy to sweat in outdoor activities, so the fabric needs to have good air permeability to keep the body dry. A common test method is to assess the breathability of a fabric by measuring its moisture permeability. The higher the moisture permeability, the better the air permeability.
In addition, water resistance is also one of the important attributes of outdoor functional fabrics. When outdoor activities, people often encounter rain, wet grass and other situations, so the fabric needs to have good waterproof performance. At present, the commonly used test method is to use the overhang method, which is to put a certain weight of water droplets on the fabric, observe the penetration of water droplets, and evaluate the waterproof performance of the fabric.
In addition to air permeability and water resistance, outdoor functional fabrics should also have wind resistance. In the outdoor environment, there is often a strong wind, which requires the fabric to have a certain ability to block the wind. A common test method is to use wind tunnel testing, by measuring the wind speed and pressure of the fabric, to evaluate the wind resistance of the fabric.
In addition, outdoor functional fabrics also need to have the ability to resist ultraviolet light, because people are easily exposed to ultraviolet light during outdoor activities. The UV resistance of the fabric can be tested by the UV transmittance, and the lower the transmittance, the stronger the UV resistance.
In summary, to identify high-quality outdoor functional fabrics, they can be evaluated from the aspects of raw materials, weaving, air permeability, water resistance, wind resistance and UV resistance. I hope this article can provide some help to outdoor lovers.
