Nylon Material Related Indicators

- Jun 11, 2019-

When customizing bags, be sure to choose the right material. Backpacks often choose fabric nylon with high material density to ensure the quality of the backpack. For nylon materials, first explain two proper nouns, D and T and their related indicators.

 D denier = g / L * 9000 where g is the weight of the wire (grams), L is the length of the wire (meters), in fact you do not need to remember what formula, it actually expresses the wire within the unit length The weight, for example, the bottom fabric of many backpacks is DuPont's 1000D nylon. Its density is very high and the wear resistance is very good. Then, in other parts of the backpack that are not easy to wear, the material can be 600D or 420D nylon. The relative density is smaller, and the larger the number before D, the more important the fabric of the same area.

 T: A unit for measuring the density of textile fibers. T=G/L*1000. That is, fiber weight / fiber length * 1000. Imitation silk fabric, generally used as the tent's outer ledger and inner account, light and strong. You can also simply think that the larger the number before T, the heavier the fabric of the same area.

 The outer material of the backpack is mainly 420D Oxford nylon, 1000D nylon, 600D or 1000Dpolyester (polyester), or 1000D CORDVRA. The 1000D material is high in density and very wear resistant, making it ideal for use in the field. CORDVRA is a well-known high-grade wear-resistant nylon roving fabric developed by DuPont of the United States. The wear resistance of this material is much higher than that of ordinary nylon or polyester, and it is light in weight.
