What are the characteristics of polyester fabric?

- Aug 16, 2019-

The polyester fabric name is polyester fiber, which is widely used in garment manufacturing and bag custom industry. Many backpacks sold in the market are made of polyester fabric.and What are the characteristics of polyester fabric?

1,good flexibility

Polyester fabric has high strength and elastic recovery. Polyester fabric has high strength and elastic recovery. Polyester fabric is durable and wrinkle-free.

2,good corrosion resistance

Polyester fabrics are resistant to bleaches, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant to dilute alkali, not afraid of mildew, but hot alkali can make it decompose. There is also strong acid and alkali resistance and UV resistance. Therefore, the finished bag made of polyester fabric has better corrosion resistance.

3,good light resistance

Lightfastness is second only to acrylic. Polyester fabrics have better lightfastness, and their lightfastness is better than natural fiber fabrics except for acrylic fibers. Especially in the back of the glass, the light fastness is very good, almost the same as acrylic fiber.

4,poor dyeability

Although the polyester fabric has poor dyeability, it has good color fastness and is not easy to fade. Once the dyeing is successful, the color is not easily faded.

5,poor hygroscopicity

The hygroscopicity of polyester is weaker than that of nylon, so the gas permeability is not as good as that of nylon. However, polyester is very easy to dry after washing, and the strength of the fabric is hardly reduced, so it is not easy to be deformed. The produced bag/backpack products are generally not deformed by washing.

6,good thermoplasticity, poor resistance to melting

Because polyester has a smooth surface and tight internal molecules, polyester is the most heat-resistant fabric in synthetic fabrics. It has thermoplastic properties. At the same time, polyester fabrics have poor resistance to melting, and they are easy to form holes in soot and sparks. Therefore, wear should avoid contact with cigarette butts, sparks, etc.

7,good wear resistance

The abrasion resistance and scratch resistance of the luggage products made of polyester material is better. If it is used normally, it can be used for a long time without deformation, no fading, no damage. Polyester fabrics have different specifications, such as 75D, 150D, 300D, 600D, Both 1200D and 1800D are polyester, and the appearance of the fabric is darker than nylon and rough.
