Polyester fabric is one of the commonly used fabric types for backpack customization, but many people do not know the characteristics of this fabric very well, nor do they know the characteristics of the backpack made of polyester fabric. Today, Love Free backpack has sorted out some relevant content for you, let's get to know.
1. Good elasticity
Polyester fabric has high strength and elastic recovery ability, so the backpack made of polyester fabric is relatively strong and durable. The backpack fabric is not easy to wrinkle during use, has good crease-resistant and iron-free performance, and the styling effect of the backpack surface is relatively good.
2. Good corrosion resistance
Polyester fabric is resistant to bleach, oxidant, hydrocarbons, ketones, petroleum products and inorganic acids. It is resistant to dilute alkali and is not afraid of mildew, but it can be decomposed by hot alkali. It also has strong acid and alkali resistance and UV resistance. Therefore, the finished backpack made of polyester fabric has good corrosion resistance.
3. Good light fastness
Light fastness is second only to acrylic fiber. The light fastness of polyester fabric is better than that of acrylic fiber, and its light fastness is better than that of natural fiber fabric. In particular, the sun resistance behind the glass is very good, almost equal to that of acrylic fiber.
4. Poor staining
Although polyester fabric has poor dyeing property, it has good color fastness and is not easy to fade. Once the dyeing is successful, the color will not fade easily. Therefore, the fabric of polyester backpack has a particularly good color fixation effect and is not easy to fade after a long time of use.
5. Poor hygroscopicity
The moisture absorption of polyester is weaker than that of nylon, so its permeability is not as good as that of nylon. However, polyester is very easy to dry after washing, and the strength of the fabric hardly decreases, so it is not easy to change shape. The backpack products produced will not deform due to washing.
6. Good thermoplasticity, poor melting resistance
Due to its smooth surface and tight internal molecular arrangement, polyester is the best heat-resistant fabric among synthetic fiber fabrics, with thermoplasticity. At the same time, polyester fabric has poor melting resistance, which is easy to form holes in the presence of soot and sparks. Therefore, try to avoid contact with cigarette butts and sparks when using.
7. Good wear resistance
The backpack product made of polyester material has good wear resistance and scratch resistance. It can be used for a long time without deformation, fading and damage if it is used normally. The polyester fabric has different specifications and grades, such as 75D, 150D, 300D, 600D, 1200D and 1800D, all of which are polyester. The fabric is darker and rougher than nylon. D is the abbreviation of DENIER. The greater the number of D, the greater the density of the material, the thicker the quality, and the better the wear resistance.
