Backpack material technology

Because backpacks are used in special environments, there are high requirements for backpack materials and processes. All backpack stressed positions are sewn three times using a sewing machine with a needle back stitch, making the stressed position sturdy and durable. The buckle and other components of the backpack can be protected against freezing, smashing, and deformation at 120 degrees Celsius without damage. The outer materials of backpacks mainly include 420D Oxford nylon, 1000D nylon, 600D or 1000D polyester, or 1000D CORDURA materials. The 1000D material has a high density and is very wear-resistant, making it suitable for outdoor use. CORDURA is a famous high-grade wear-resistant nylon roving fabric developed by DuPont Company in the United States. The abrasion resistance of this material is much higher than that of ordinary nylon or polyester, and it is light in weight. More than 90% of the backpacks of famous brands in the world use this prestigious nylon material. These materials can withstand water pressure of 0.5 m to 2 m to keep the contents of the bag dry. Some materials also have a tear resistant function, so once punctured, the tear will not tear and expand.
