what IS polyester FABRIC?

red polyester fabric in Kamer Fabrcic

Polyester is a highly preferred fabric in today’s fashion. Polyester is a type of artificial fiber used in textiles. Its acronym is PES. Polyester is a category of polymers, or more specifically, condensation polymers containing ester functional groups within their main bonds. It is not a natural fabric like cotton, wool, silk, but a factory production. Although it is not natural, it is used frequently due to some properties. Although polyesters are not found in nature, polyester generally refers to a large family of synthetic polyesters including all polyethylene terephthalate and polycarbonate.

Polyester fabric was invented in England in 1940. It earned its reputation in the 1970s by advertising that it can still look stylish without ironing for 68 days. It was a very famous fabric at that time, and many discotheque clothes were made of polyester.

100% polyester fabric can be preferred for garment sewing or coating work, as well as mixed with natural yarns. If you look at the clothes you have already bought, you can see phrases such as 70% cotton and 30% polyester on their labels. Since polyester does not wrinkle structurally and is flexible, it is aimed to reduce the wrinkling rate of natural fabrics and to provide flexibility by mixing with natural fabrics.

Polyester fibers mixed mostly with cotton fiber can be used with wool, acrylic, silk, viscose, and linen fiber. England Terylene, Trevira, Dacron in the United States, diol, and polyester fibers produced by the trade name Peril in Turkey is the most widely used synthetic fiber location in Germany today. It is a fiber that is easy to obtain and is close to natural fibers. It is an artificial fiber that has the closest properties to cotton. With the increasing need for cotton, polyester fibers have become more prominent. The polyester obtained as a result of the condensation of a dicarboxylic acid with a dialcol is examined in 3 groups in terms of its chemical structure.

  1. PET (polyethylene terephthalate) fibers,
  2. PCDT (poly-1.4 cyclohexyl-dimethylene-terephthalate) fibers,
  3. Modified (new) polyester fibers.

Physical Properties of Polyester Fibers

    • Cross-section and longitudinal view: Polyester fibers are seen as a smooth rod under the microscope. Its cross-section is round.
    • Color and brightness: Polyester fibers are generally produced in white. Polyester fibers are shiny, they can be obtained as semi-dull or matte if desired.
    • Fineness and length: Polyester fibers can be produced in various lengths. Depending on the area of ​​use, it can be either filament or staple.
    • Strength: The strength of polyester fibers varies according to the type of production. The strength of polyester fibers in filament form is between 4-7 gr/denier.
    • Moisture absorption: Polyester fibers have very low moisture absorption. This rate varies between 0.2-0.8% under normal conditions. Since polyester fibers can keep moisture on the surface without absorbing moisture, the products with polyester fabric produced can be worn in hot weather.
    • Friction resistance: Polyester fibers have very good resistance to friction. Pilling problems may be encountered in pes fabrics.
    • Non-dimensional change: Polyester fibers applied with a hot fixation process have very good dimensional stability. Hot-set polyester fabrics can shrink at high temperatures.
    • Flexibility and spring feature: Polyester fibers have generally good elasticity and very good springiness. The elongation rate of polyester fibers in filament form varies between 15-30% and 30-50% in batch form.
    • Volumetric density: Polyester fibers are light fibers and their specific gravity is 1.38 gr / cm³.

Polyester fabric preference reasons:

  • Polyester fabric is bright, strong, flexible, slippery, and light fabric.
  • It dries easily. It is preferred in outer clothes due to its quick drying.
  • Does not require much ironing, does not crease. It keeps the shape given by ironing for a long time.
  • It is soft and silky to the touch.
  • It is very easy to maintain, machine washable at home. It does not require dry cleaning.
  • In addition, it does not cause traces due to use. You know, we complain a lot about the knee mark on pants and pajamas, there is no such problem with polyester.
  • It is not affected by moth and harmful insects.
  • Likewise, it is not damaged by microorganisms such as mold and fungus.
  • It is cheap.
  • Although polyester is preferred due to its easy drying, being durable and flexible, being easy to clean, and not requiring ironing, it has some negative features.

Polyester fabric damages:

  • Does not breathe, does not absorb sweat, and makes you sweat. It can overwhelm you with moisture because it does not take the air. It is not worn in summer.
  • It makes static electricity. When you wear polyester, you can hit the people you touch.
  • Static electrification also affects your mood and can make you aggressive and nervous.
  • Like natural fabrics, it may not be in harmony with your skin and may cause allergies.
  • It should keep away from fire, it can burn easily.

Is Polyester Fabric Healthy?

In short, polyester fabric is not considered healthy. Although natural fabrics are more expensive, washing and drying require more labor, they are preferred. Because of these issues, polyester is usually mixed with natural fabrics and produced. For example, its version when mixed with cotton is called polycotton. Thus, it contains the properties of both fabrics.

I used to see polycotton fabric on bed linens, if you intend to buy duvet cover sets, pay attention to their fabrics, it would be healthier to choose one hundred percent cotton, sleep is important. Also, pay attention to polyester blends in baby products. It is useful to use 100 percent natural products for baby skin.


Where Is Polyester Fabric Used?

It is used in sportswear, climbing suits, making coats, suitcases, and bags, shoes, sewing and embroidery threads, sleeping bags, tents and raincoats, curtains, and bedspreads. It is especially preferred in these areas for the convenience of washing and drying. In addition, it is mixed with natural yarns (such as cotton, wool, silk) and used in many clothing products.

  1. Tarpaulin (tent)
  2. Curtain (tulle)
  3. Raincoat (jacket)


Things to Consider When Sewing Polyester Fabrics

Polyester fabric does not absorb moisture, so it does not shrink. If you have 100% polyester fabric, you do not need to wash it before sewing as it will not shrink. It is recommended to wash before cutting, as it may shrink on fabrics made of natural yarn and its blends.


The Difference Between Nylon and Polyester

You can use polyester mesh using nylon mesh in many applications and processes. However, there is a difference between the two materials. Nylon and polyester can be made by synthetic processes involving hot plastic polymers. However, nylon is made from polyamide, and polyester is made from various polyesters and can be made using plant materials. While nylon looks like silk, polyester usually has more effect likes fiber. With regard to flexibility, nylon can be stretched.
