Recently, in order to buy a 17-inch computer bag, I went to many stores and found that school bags and travel bags can hold laptops, but generally only 14-15-inch laptops. For 17-inch large laptops, you need to buy a special laptop bag.
But in terms of quality, it is mainly the material and the design inside. The lining and fabric are polyester fiber, commonly known as polyester. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery. , Strong and durable, anti-wrinkle, non-iron, non-stick hair. Polyester is widely used in apparel fabrics. Polyester has excellent wrinkle resistance, elasticity and dimensional stability, and good insulation properties.
In addition, polyester fabrics have good resistance to various chemicals and are not damaged by acids and alkalis. At the same time, they are not afraid of mold or insects.
The back ventilation function is designed inside, and the special wave shoulder strap design makes it light and comfortable to carry on the back.
It is better to have a special computer bag, which has a special computer bag, as well as many built-in bags for small things, such as mobile phones, key chains, signature pens, CDs, external storage bags for water bottles, and so on.
1. Backpack computer bag: similar to the student backpack, the student bag can also be used as a computer bag, but it is generally a 14-15-inch laptop, and a 17-inch large laptop needs a special computer bag. A large laptop won't fit in your bag if you don't buy it properly.
There is no problem in placing a 14-15-inch laptop in a general computer bag. If you want to place a 17-inch laptop, pay attention to the width of the bag opening to choose 27cm, and the bag opening width of 24cm can only hold 14-15-inch laptops.
2. Portable computer bag: Pay attention to the height of the handbag when purchasing. The height of the 14-15 inch laptop is 24cm, and the height of the 17-inch laptop is 27cm.
If you do not pay attention to the height of this bag when purchasing, the large notebook will not fit.
Third, choose a computer bag according to the size of the laptop.
The 17-inch computer is 27cm wide and 39cm long.
14 inches is 24cm wide and 35cm long.
Fourth, some computer-specific bags are also equipped with keychains and mobile phone headphone cables (the headphone jack is on the strap, or you need to prepare another pair of headphones, and there are only headphone plugs in the bag).
Five, cleaning and maintenance
Soak in clean water and detergent for a few minutes. Water at natural temperature (below 30 degrees) must not be used with hot water, because hot water can easily melt stains into clothing fibers or burn the material.
Or wash in cold water, add detergent, brush several times with a laundry brush, rinse with water several times, and dry in a cool and ventilated place. Do not expose to the sun.
