The accessories of the backpack are important, and the knowledge of the two accessories is best understood when choosing a computer backpack. There are two main types, the first is the handle. The second is the zipper slider. Let's learn about it together. 1.
Handle handle is one of the places where computer backpacks are tested by gravity, which is often the most deadly detail.
There are two kinds of computer backpack handles, one is aluminum handle and the other is nylon handle.
The aluminum joint handle depends on whether the aluminum joint does not fade, and the surface is knocked by hand to see if there is any empty sound. If so, it indicates that there is no webbing in the aluminum joint, which is not enough for reinforcement.
Let's look at the grip. If the handle is full, it can conform to the human Handle System;
The third is to pull, pull one to three times, test whether the webbing in the handle is tight with the top of the seam, in order to use for a long time. Let's look at the nylon handle.
Nylon handles are used in traditional computer backpack styles. Nylon with higher density is strong and durable, and the quality is guaranteed. In addition to its own quality, nylon handles should choose large handles, it is not easy to hurt when extracting;
Let's look at the tightness of the nylon handle and the top of the bag. It is more important to check whether there is secondary reinforcement in the sewing. 2.
Zipper slider the zipper of the backpack is generally rigorous and fashionable in business, so the backpack basically uses the No. 5 zipper, which is exquisite and tight, when you choose a zipper, you should pull it directly. It is feasible if you pull it back and forth.
Then, the waterproof property of the zipper is commonly used as a waterproof nylon zipper. Because nylon itself does not absorb water, it is developed with nylon material. The main test method is the degree of compression.
If you choose a plastic slider, check its firmness;
If you choose a metal slider, check its metal density; The silicone slider will check his toughness.
The slider is actually one of the design features of the backpack. His design is to use a double slider design to open and close the backpack opening from both sides, which is convenient and convenient to use, therefore, the long-term damage of the slider is reduced and the service life of the zipper is prolonged.
