With the rapid economic development, people hope to be able to work anytime, anywhere, so small and light notebook computers are becoming more and more popular among business people. To carry a laptop computer, it is often necessary to be equipped with a laptop briefcase. There are many choices of materials for laptop briefcases, but no matter what kind of laptop briefcases, they must meet certain requirements. What requirements must they meet? Here are some introductions.

Here is the content list:

• Wear-resistant and durable

• Requires multiple and thick compartments

Waterproof

The outer surface of the laptop briefcase needs to be made of a waterproof fabric so that it can protect the laptop and laptop briefcase itself from natural rain and snow. Rainproof cloth leather and new organic waterproof materials are materials that can be used on the outer surface of laptop briefcases. Therefore, the material of the laptop briefcase must be waterproof, otherwise, it will easily cause damage to the computer circuit.

Wear-resistant and durable

It is wear-resistant because notebook computers are relatively expensive electronic products, such as LCD screens, hard drives, and many internal chips, which are fragile and have poor shock resistance, and require careful care. The bumps in the carrying process of the laptop briefcase and the hard object caused by carelessness will pose a threat to the safety of the notebook. Portable computer briefcases are prone to unfavorable factors such as scratches and friction, so wear resistance is very important. Durability is because the weight of the computer is very heavy. The laptop briefcase must be durable or it will be damaged.

Requires multiple and thick compartments

In addition to basic equipment such as the laptop itself, mouse, power cord, and power adapter, laptop users may also carry portable storage devices such as CDs, U disks, mobile hard drives, and MP3s. They can also carry a small number of books, paper, and pens. Or bring some personal items such as mobile phones, cigarettes, vanity mirrors, facial tissues, and so on. The design of the laptop briefcase must take into account the storage space for these possible items to facilitate the user to carry the possible related items. At the same time, the charger, mouse, computer, etc. placed in a compartment will cause electromagnetic interaction, so the compartment of the laptop briefcase is needed to separate them. Thickness requires that the material of the laptop briefcase should be rough, generally made of thick fiber, if the surface is too delicate, it will easily cause damage to the surface of the laptop briefcase.

There are two types of Laptop backpacks, one-shoulder Laptop Backpacks, and double-shoulder Laptop Backpacks. When we buy Laptop Backpacks, Laptop Backpacks provided by the merchants are single-shoulder Laptop Backpacks, but the mainstream Laptop Backpacks are double-shoulder designs. What is the difference between the two? The comparison between one-shoulder Laptop Backpack and double-shoulder Laptop Backpack. Here are some answers.

• Laptop Backpacks with two shoulders protect human health more than Laptop Backpacks with one shoulder.

• Laptop Backpacks with two shoulders protect human health more than Laptop Backpacks with one shoulder.

• Features of Laptop Backpacks.

• The size of the Laptop Backpack should be matched reasonably.

Comparison of the comfort of one-shoulder Laptop Backpack and double-shoulder Laptop Backpacks.

We have learned about pressure in junior high school physics. Under the same weight, the smaller the force area, the greater the pressure! Therefore, from the perspective of comfort, a double-shoulder Laptop Backpack will be more comfortable than a one-shoulder Laptop Backpack, because the double-shoulder Laptop Backpacks will spread the pressure on the shoulders and back, while the one-shoulder Laptop Backpacks only gives one shoulder weight. Pressure.

Laptop Backpacks with two shoulders protect human health more than Laptop Backpacks with one shoulder.

Laptop Backpacks with two shoulders protect human health more than Laptop Backpacks with one shoulder. Because the pressure on the one-shoulder Laptop Backpack is on one side when carrying heavy objects, it is easy to cause deformation or damage to the spine. Over time, you will feel that one shoulder is unbearable. Therefore, the two-shoulder Laptop Backpack is the healthiest to the human body compared to the one-shoulder Laptop Backpack.

Features of Laptop Backpacks.

The double-shoulder Laptop Backpack can carry more heavy loads, and the capacity is much larger than the single-shoulder Laptop Backpack. When the laptop is not installed, the two-shoulder Laptop Backpack can also be used as a sports backpack or a travel backpack.

A Laptop Backpack with two shoulders protects the laptop better than a Laptop Backpack with one shoulder.

From the protection of laptops, a Laptop Backpack with two shoulders protects the laptop better than a Laptop Backpack with one shoulder. The reason is that the double-shoulder Laptop Backpack fixes the laptop on the back, which effectively reduces the collision of the laptop and reduces the sloshing of the laptop. The one-shoulder Laptop Backpack puts the laptop on one side of the body and cannot be properly secured.

The size of the Laptop Backpack should be matched reasonably.

Generally, a Laptop Backpack with a height of 17 inches and 30 cm diagonally (that can hold 15.6 notebooks) is recommended. However, if the Laptop Backpack has a large margin on both sides of the upper half of the space, it will seriously affect the assembly capacity. The Laptop Backpack is large, but it is not durable.

Canvas Backpacks is the darling of the fashion industry. Many people mistakenly believe that Canvas Backpacks are just beautiful, but the material and workmanship of Canvas Backpacks are also very important. A great Canvas Backpack must be measured and refined from the following four aspects. How to choose a high-quality Canvas Backpack? Here are some answers.

Here is the content list:

• Raw materials for Canvas Backpacks.

• It depends on the lining and accessories of the Canvas Backpack.

• It depends on the color of the Canvas Backpack.

• It depends on the workmanship of the Canvas Backpacks.

Raw materials for Canvas Backpacks.

If the Canvas backpack is a good canvas, it feels delicate to the touch. The canvas used to make the Canvas backpack is a piece of coarse hemp fabric, and it must be textured, but a good canvas has a clear texture and a uniform and delicate feeling to the touch. The Canvas Backpacks with poorer quality fabrics feel rough or even stiff.

It depends on the lining and accessories of the Canvas Backpack.

Compared with the cotton lining of the Canvas Backpacks, the price is higher than that of the chemical fiber. The quality is of course stronger, not easy to draw, and the hand feels first-class. Maybe we often encounter this situation: the appearance of the Canvas Backpacks is not bad, the lining is torn first, so when customizing the Canvas Backpacks, the lining of the Canvas Backpacks is also very important, and the detail of the lining cannot be ignored.

It depends on the color of the Canvas Backpack.

Compared with other fabric backpacks and leather bags, Canvas Backpacks have always fewer colors to choose from (some dyeing added in the later period can't be counted). The main reason is that the color fixation problem of canvas fabrics has not been solved well, and the vividness of the colors cannot be highlighted. Therefore, for the color, when choosing the LOGO of the Canvas backpack and Canvas Backpacks body, special attention should be paid to whether the color is uniform and the color is faded.

It depends on the workmanship of the Canvas Backpacks.

The finer the stitch stitching of the Canvas Backpacks, the stronger the Canvas Backpacks, the less easy it is to open the thread. Therefore, when checking the quality of the Canvas Backpacks, regardless of whether the Canvas Backpacks is sewn with open or dark threads, the stitch length should be uniform, and there should be no thread exposed. Pay attention to whether the stitching is free of wrinkles and whether the threads are all reached. Whether the cable end will cause the package to crack. The details determine the quality of the Canvas Backpacks.

Compared with the Laptop Backpack made of nylon fabric that is resistant to deformation, the biggest feature of the Laptop Backpack made of nylon fabric is just the opposite.

The first category is natural materials, which are treated by dehairing, tanning, or other special methods from the skin of animals; the second category is artificial leather, including regenerated leather and artificial leather. And three kinds of synthetic leather. The uniform feature of the leather is comfortable to the touch, and at the same time, it can make the finished product a higher grade. Artificial leather and synthetic leather are made of woven fabric base or non-woven fabric base, respectively coated with polyurethane and made by special foaming treatment. The surface feels exactly like real leather, but its breathability, abrasion resistance, and cold resistance are not as good as leather. However, as a material for making Laptop Backpacks, the shortcomings of artificial leather are generally not considered. Therefore, it is also widely used in high-end Laptop Backpacks. Even some international top brands use artificial leather as the main production of laptops. Backpack surface material.

Canvas is also a material for making Laptop Backpacks.

Canvas is also a material for making Laptop Backpacks. The canvas feels thicker, and the weight is heavy. The Laptop backpack made is rough, but they are not very functional. Moreover, the scratch-resistant performance of the Laptop Backpack made of canvas is not very good, and it is easy to be scratched by a sharp blade to leave permanent scars on the surface. However, some designers use this feature of canvas to deliberately scratch or open to achieve the desired special effect.
