So today, when light and strong nylon materials are widely used, let us see what kind of nylon is most suitable for your requirements?
First explain the two proper nouns , D and T.
D---denier=g/L*9000, where g is the weight of the silk thread (grams), and L is the length of the silk thread (meters). In fact, you don’t need to remember any formula. It actually expresses the weight of the thread per unit length. For example, the bottom fabric of many backpacks is made of DuPont’s 1000D nylon, which has a very high density and is very wear-resistant. Then, in other parts of the backpack that are not easy to wear, The material can be 600D or 420D nylon, and their relative densities are smaller. The larger the number before D, the heavier the cloth of the same area. Usually tents use 150D or 70D nylon to take into account cost/weight/wear resistance. However, some high-end super light tents, such as MHW’s Annapurna, use 30D and 40D fabrics to minimize weight, at the expense of cost. A significant increase in and a decrease in relative wear resistance.
T--The T in fabric generally refers to polyester taffeta, which is a nylon, silk-like fabric. It is generally used as the outer and inner tents of tents. It is light and strong, such as 190T , the number in front of it represents the sum of the number (density) of warp and weft yarns in 1 inch (2.545CM), which is actually a unit of density. You can also simply think that the larger the number before T, the larger the cloth of the same area. Heavy. For external tents, considering their vulnerability to damage in harsh environments, attention should be paid to whether they have a ripstop structure, which is simply woven into a small square pattern. Even if one point is damaged, it will not be torn apart in strong winds. The bigger.
The outer material of the backpack is made of dense, waterproof, wear-resistant, flame-proof, and tear-proof materials. It is mostly made of man-made fiber (Kodra) and high-density nylon cloth (Hi-density Nylon Oxford). Generally, D To distinguish their functions, such as 420D Oxford nylon, 1000D Kodra nylon, etc., the higher the performance, the better, the more professional they are, and some of their sutures are treated with waterproof spray film.
The outer materials of backpacks mainly include 420D Oxford nylon, 1000D nylon, 600D or 1000D polyester (polyester), or 1000D CORDVRA and other materials. 1000D material has high density and is very wear-resistant, making it suitable for use in the wild. CORDVRA is a well-known high-end wear-resistant nylon roving fabric developed by the American DuPont Company. The material is far more abrasion resistant than regular nylon or polyester and is lightweight. More than 90% of the world's famous brand backpacks use this prestigious nylon material.
