5 Aspects To Examine The Quality Of The Backpack

Materials used: Oxford cloth, nylon and polyester cloth of 300D to 600D are generally used, but the texture, abrasion resistance, color and coating will be different. The best is the DuPont CORDURA fabric, which is strong, abrasion-resistant, tear-resistant, and has better performance than other fibers. Recently, an ultra-light CORDRA has been released, which can minimize the weight of the bag. The material used for the bottom of the bag is stronger than the fabric, usually 1000D nylon cloth is used more. Design: bag shape, carrying system, space allocation, small bag configuration, external hanging design, back heat dissipation and perspiration, rain cover, etc. Good backpacks have outstanding advantages in design.

Accessories: Zippers, fasteners, closing ropes, nylon straps are very particular. There are plastic-steel parts and nylon parts. The plastic-steel parts feel better, have high hardness, and have a louder and crisper sound. Nylon parts have better toughness and greater elasticity. The compression webbing has a big difference, and it can be seen at a glance whether it is good or bad. The Hong Kong Shengji webbing that is more frequently used now is tight, firm and good in appearance.

Process: The level of processing technology is determined by the skill of the workers and machinery and equipment, such as multi-function double-needle machine, knotting machine, one-time molding compression molding machine, laminating machine, etc. Program design and quality supervision also play an important role. Visiting some backpack processing factories will have a perceptual understanding of the whole process.
