Outdoor Jackets fabric with characteristics analysis date: 2016-08-31 14:54
There are many kinds of outdoor sportswear, mainly for alpine sports such as mountaineering and skiing. In addition to the physical energy and skill requirements of the participants, outdoor sports also require clothing with bad weather and complicated geographical environment. The requirements for outdoor fabrics are discussed below for different environments and different professions.
(1) Selection and application of waterproof and moisture-permeable outdoor fabrics Outdoor sports clubs will disperse a large amount of sweat, but outdoor and inevitably encountered wind and rain weather, which in itself is a pair of contradictions, we must be able to prevent rain and snow from soaking, but also in a timely manner Exhaled sweat from the body drains. Fortunately, the body evaporates water vapor in a single molecule state. Waterproof and breathable clothing is to use the surface tension of water, apply a layer of PTFE on the fabric (the chemical composition of the polytetrafluoroethylene PTFE with the king of corrosion resistant fibers and the physical structure is different) to strengthen the fabric surface with a strong chemical coating Layer, so that the water droplets as much as possible to absorb and can not spread, infiltrate the surface of the fabric, which can not penetrate the pores of the fabric tissue. At the same time, the coating is porous, and the water vapor in the single-molecule state can be smoothly transmitted through the capillary pores of the fiber surface to the fabric surface. After a relatively large amount of exercise, stopping in the wild may be due to low outside temperatures. Sweat can not escape in time and form water droplets in the inner layer of clothing, which makes people feel uncomfortable. This is the so-called condensation phenomenon. There is a special moisture permeable finishing process called low condensation, which uses polyurethane (pu) and hydrophilic nano-ceramic powders to coat fabrics and absorb them when the body evaporates large amounts of sweat. The sweat vapor, thus avoiding the phenomenon that the water vapor inside the clothes exceeds the saturated vapor pressure and turns into water droplets. In addition to formulating ideas for fibers and coatings, moisture can be absorbed as much as possible on fabric structures. For example, with a double-layered structure, the close-fitting inner layer uses hydrophobic fibers and the outer layer uses hydrophilic fibers to bind the water molecules stronger than the inner hydrophobic fibers, and the water molecules are transferred from the inner layer of the fabric to the outer layer again. Evaporate into the atmosphere. This type of branded apparel fabrics are mostly used for hiking, hiking and other outdoor clothing.
(B) warmth of the characteristics of outdoor fabrics and applications Although the warmth is closely related to the thickness of the fabric, but outdoor sports do not allow clothing too thick, so it is necessary to keep warm but also light to meet the special requirements of outdoor sportswear. The most common method is the addition of special ceramic powders containing chromium oxide, magnesium oxide, silicon oxide, etc. to synthetic fiber spinning fluids such as polyester, especially nano-sized fine ceramic powders. He can absorb visible light such as sunlight and convert it into heat energy. Can also reflect the body's own far-infrared radiation, so it has excellent insulation, heat storage function. Of course, the far-infrared ceramic powder binder and the cross-linking agent can also be formulated into a finishing agent, the woven fabric is coated, and the nano-ceramic powder adheres to the surface of the fabric and the surface of the yarn after being dried and baked. . Has played a very good warming effect. In addition, according to the bionics principle, referring to the structure of the polar bear hair, the inside of the polyester fiber is made porous so as to make the inside of the fiber contain a large amount of non-circulating air. The outer part is made of spiral crimp to keep the fluffy, and it can maintain a good insulation effect under the premise of maintaining the lightness of the place. Of course, making clothes and even fabrics into two or three layers is one of the most popular measures for keeping warm without increasing the air layer. The well-known outdoor product brand Supreme will launch in October a new autumn garment made from the latest GALEFLEECE premium fabrics. This fabric is very common FL-EECE (Fleece) fabric breathable, lightweight and professional WINDSTOPPER functional fabric excellent windproof, warm performance in one. You can keep it in good wind, warmth, and certain water-pulling properties under harsh conditions such as cold winds. It is mostly used for professional outdoor clothing such as alpine skiing and boarding.
(C) Anti-bacterial and deodorant outdoor apparel fabrics Outdoor sports often produce a large amount of sweat, resulting in a large number of sebaceous glands, while outdoor conditions can not always change clothes, in a suitable temperature and humidity environment, microbes will multiply, Therefore, regular outdoor sportswear is finished through antibacterial and deodorant chemistry. The method of finishing is generally the organic polyamine type, the imidazoline type surfactant or the silver, copper and other metal ions having the function of collecting bacteria, and the resin and the hinge agent are fixed on the fibers to have certain washability. Of course, an important principle for the selection of fungicides is definitely non-toxic or low-toxic. In recent years, Japan has done a lot of research on the research of natural antibacterial finishing agents. For example, it uses bactericidal effects such as aloe vera, artemisia leaves, loquat leaves, and roses. Aromatic oil extracts are coated on porous organic microcapsules or porous ceramic powders and adhered to fabrics. They are fixed by a resin and are slowly released by a mechanical action such as friction backlog to achieve a durable antibacterial finish. purpose. However, since the means for fixing the antibacterial agent are currently limited, the antibacterial agent has insufficient washability, and the antibacterial property decreases with each washing, and generally disappears after several dozen times. US Dow Corns AEGIS anti-microbial antibacterial agent adopts the molecular link method to distribute eighteen long carbon chains evenly on the surface of the fabric and integrates with the fabric fibers. This fabric is used with outdoor clothing for mountaineering and field training, travel vacations. It is the fabric of choice for professional and strong jackets. Now the domestic well-made Jackets for children's adult brands are: High Experience, camels, Pathfinder, and so on.
