When customizing a backpack, it is often encountered that customers directly ask the manufacturer to quote the number of D fabrics, such as 210D polyester, 840D double-strand nylon, 1680D Oxford cloth, etc. Those who know it will naturally know how much "D" should be used for what style of backpack. If you don’t know the number of fabrics, you have to ask the backpack manufacturer to recommend the appropriate “D” number of fabrics according to the needs of the customizer. So, for backpack customization, is the higher the "D" number of the fabric, the better? Regarding this question, I will give you an answer to this question today.
To answer the above questions, you must first have a specific understanding of what the "D" number in the fabric means. "D" in backpack fabric is the abbreviation of "Denier", also known as "denier" or denier. For example, the weight of 1 gram of fiber at 9000 meters is 1 denier (that is, 1D). If the weight of fiber at 9000 meters is 600 grams, it is 600D. To accurately distinguish, it is necessary to calculate D=9000*weight (grams)/length ( Meter). When the density of the fiber is constant, the larger the denier, the thicker the fiber.
From the appearance of the fabric alone, the larger the D number, the thicker the fiber, and the thicker and stronger the finished fabric will be. On the contrary, the smaller the D number, the thinner the fiber, and the lighter and thinner the finished fabric will be.
Although the larger the "D" number of the fabric, the stronger it is, but the fabric is customized for the backpack. The "D" number of the fabric is not to say that the higher the better, the key is to choose the appropriate "D" according to the appearance of the backpack, the purpose of the backpack and the use of the fabric. number of fabrics. Like some ordinary daily backpacks, the main materials are mostly 300D, 420D, 600D and above denier fabrics. The finished backpacks have a delicate and textured appearance, light weight, strong and durable functions. Backpack lining fabrics are mostly made of smaller denier fabrics such as 150D and 210D, which are lighter and softer, and are more suitable for backpack lining than larger denier fabrics. However, if you customize an outdoor tool backpack, because the outdoor tool backpack has higher requirements on the bearing capacity and durability of the fabric, the fabric with high denier is more suitable. For example, 1680D fabric is one of the commonly used fabrics for customized tool backpacks. Low fabric bearing capacity, better wear resistance and durability, more suitable for outdoor tool bag backpacks. Therefore, the customization of the backpack does not mean that the higher the "D" number of the fabric, the better, it is the kingly way to see if the fabric is suitable!
