Because the computer bag needs to estimate many characteristics, the material selection is more particular, usually using several common materials such as cowhide material, Oxford cloth, nylon and polyester fiber. Generally speaking, the most economical and durable computer bags are made of nylon and polyester fibers.
1. Cowhide material: as long as you keep it properly, the luggage is very valuable, and using genuine leather is not environmentally friendly. And cowhide computer bag material is the most expensive, and there are many shortcomings. In terms of cost performance, it is also afraid of water, abrasion, pressure, and scratching.
2. Oxford cloth material: This material is similar to nylon, belongs to the fabric material, and is very wear-resistant. The disadvantage is that this material is the same and heavier, but it is not necessary to worry about the damage to the bag when it is often carried out. It has been used for a few years and it is still the same as before. With the increase of time, the surface of the Oxford cloth will wear and tear, and it may appear for a long time after a few uses.
Oxford cloth: also known as Oxford spinning, originally colored fabric. It has the characteristics of easy washing and quick drying, soft hand feeling, good hygroscopicity and comfortable wearing. Oxford cloth is mostly made of polyester-cotton blended yarn and cotton yarn, and adopts weft weight flat or square flat weave.
3. Many computer bags on the market are made of nylon. The main features of nylon fabrics are:
①The abrasion resistance of nylon fabric ranks first among all kinds of fabrics, which is many times higher than that of other fiber fabrics of similar products, so it has excellent durability.
②The hygroscopicity of nylon fabrics is the best among synthetic fiber fabrics, so bags made of nylon will be more comfortable and breathable to carry.
③Nylon is a lightweight fabric, and the weight of the bag produced will be lighter than that of other fabrics, which is more conducive to travel.
④Nylon fabric has excellent elasticity and elastic recovery, but it is easy to deform under the action of external force, so the computer bag made of nylon fabric needs special protection.
⑤Nylon fabric has poor heat resistance and light resistance, so pay attention to the conditions of washing and maintenance during use, so as not to damage the fabric fibers.
4. Polyester fiber, also known as polyester, is not only commonly used in clothing, but it is also a good backpack fabric. The only characteristics of polyester are:
①Polyester fabric has high strength and elastic recovery ability, so the bag made of polyester fabric is firm and durable, wrinkle-resistant and iron-free.
②The hygroscopicity of polyester is weaker than that of nylon, so the air permeability is not as good as that of nylon, but polyester is very easy to dry after washing, and the strength of the fabric hardly decreases, so it is not easy to deform.
③Polyester fabric is the chemical fiber fabric with the best heat resistance. It has thermoplasticity. The pleats made with it are durable. However, polyester has poor solvent resistance, so bags made of polyester fabrics should try to avoid contact with high-temperature items such as cigarette butts.
④The light fastness of polyester fabrics is better, and its light fastness is better than that of many natural fiber fabrics, especially the light fastness behind glass is very good, which is more suitable for outdoor sports users.
⑤Polyester fabric has good resistance to various chemicals, acid and alkali damage to it is not large, and it is not afraid of mildew and insect bites.
