Understanding what polyester is is important for those who frequently encounter this material in various everyday textile products. Polyester is a synthetic fiber that is widely used because its characteristics support a wide range of clothing needs.
Its lightweight, strong, quick-drying, and wrinkle-resistant properties make polyester popular for various applications. This material also has a slightly glossy appearance, making it easy to recognize in certain types of fabric.
Although it offers many advantages, polyester also has several drawbacks that need to be considered. So, what makes this material so widely used? Read the complete explanation below!
What Is Polyester?
Polyester is a type of synthetic fiber widely used in the textile and fashion industries. Unlike natural fibers such as cotton, which come from plants, polyester is produced through chemical processes using raw materials derived from crude oil or petroleum.
The material is then processed into fibers that can be used to manufacture various textile products. In general, polyester is made from polyethylene terephthalate, or PET, which is produced by combining ethylene glycol and terephthalic acid.
Manufacturers can use polyester as 100% polyester or blend it with other fibers, such as cotton, spandex, and rayon. These blends can produce fabrics that are softer, more flexible, and more comfortable to wear.
How Is Polyester Made?
The textile industry generally uses two methods to produce polyester. Each method involves different raw materials and production processes, as follows.
1. Standard Polyester (Virgin Polyester)
Manufacturers produce virgin polyester through a chemical reaction between ethylene glycol and terephthalic acid to produce polyethylene terephthalate (PET). Once formed, the PET undergoes heating and processing until it becomes fibers suitable for textile applications.
Manufacturers then spin these fibers into yarn. The yarn can be woven or knitted to produce sheets of fabric ready to be used in various products.
2. Recycled Polyester (rPET)
Recycled polyester, or rPET, reuses plastic waste containing PET, such as used beverage bottles. This method helps reduce the use of new raw materials while making use of plastic waste that can still be processed.
Manufacturers collect and clean used bottles before shredding them into small flakes. The flakes are then melted and reprocessed into fibers. Manufacturers subsequently spin the fibers into yarn to produce new fabric.
Characteristics of Polyester Fabric
Polyester has several characteristics that make it widely used for clothing and various textile products. Its fiber properties provide good durability while making everyday care easier.
In addition to being strong and lightweight, this material can maintain its shape and dry quickly. Here are some polyester characteristics you should know.
- Very strong and durable: Polyester fibers have high durability, making them resistant to tearing, stretching, and shrinking even after repeated washing.
- Wrinkle-resistant: Polyester can maintain its shape well, allowing the fabric to remain neat without requiring frequent ironing.
- Lightweight and quick-drying: Polyester fibers absorb only a small amount of water, allowing the fabric to dry relatively quickly.
- Excellent color retention: Polyester fibers can bind dyes effectively, producing bright and relatively long-lasting colors. This characteristic also makes polyester suitable for sublimation digital printing techniques.

2. Disadvantages of Polyester
However, polyester also has several limitations. Its synthetic fiber properties can affect comfort and create certain environmental challenges. Here are some of its disadvantages.
- Less breathable**:** Polyester has a lower ability to absorb sweat and allow air to circulate, which can make it feel hot, especially in hot weather or during physical activity.
- Tends to retain odors: Sweat that is not absorbed effectively can remain trapped in the fibers, making garments more likely to develop unpleasant odors.
- Difficult to naturally decompose: Polyester is made from synthetic materials and therefore takes a very long time to break down. Washing can also release microplastic fibers into the environment.
- May cause irritation: Polyester can cause itching or discomfort for some people with sensitive skin.
- Sensitive to high temperatures: Polyester fibers can melt or burn when exposed to high-temperature heat sources or flames.
Types of Polyester in the Textile Industry
The textile industry uses several types of polyester to produce products with different characteristics. Here are some of the most commonly used types of polyester in the textile industry.
1. Polyethylene Terephthalate (PET)
Polyethylene Terephthalate (PET) is the most widely produced and used type of polyester. This fiber has high strength and can withstand exposure to various chemicals.
Manufacturers often use PET to produce t-shirts, jackets, sportswear, and various everyday garments. In addition to being strong, PET also offers the advantage of being recyclable. These characteristics make it relevant for various textile production needs.
2. Poly-1,4-Cyclohexylene-Dimethylene Terephthalate (PCDT)
Poly-1,4-Cyclohexylene-Dimethylene Terephthalate (PCDT) offers better elasticity and flexibility. This fiber is also resistant to tearing, allowing manufacturers to use it for products that require more flexible materials.
Manufacturers more commonly use PCDT for home decoration applications rather than clothing. Examples include curtains, tablecloths, and chair covers.
3. Polyester Microfiber
Polyester microfiber uses extremely fine fibers to produce fabric with a soft texture. This characteristic makes the material comfortable when it comes into direct contact with the skin.
Manufacturers can use it to make sleepwear, underwear, bed sheets, towels, and various other household textile products.
4. Polyester Blends
Manufacturers can blend polyester with other fibers, such as cotton, rayon, or spandex. This process aims to produce fabric with more balanced characteristics than pure polyester.
These blends can make the fabric softer, more flexible, and more comfortable to use. Manufacturers can also adjust the fiber composition according to the requirements of the final product.
Uses of Polyester for Various Textile Products
The choice of fabric should still be adjusted to the function of the product. Some products require quick-drying fabric, while others prioritize strength, elasticity, or moisture resistance.
1. Sportswear and Jerseys

Tips for Choosing Polyester Fabric for Production Needs
Before starting large-scale production, test the material that will be used. This step helps ensure that the fabric can deliver the required results while reducing the risk of production errors.
1. Conduct a Test Print or Sample Test
Conduct a sample test print before starting large-scale production. This test helps you determine whether the fabric is compatible with the printing method being used.
Differences in fiber composition, fabric weight, coating, and finishing can affect color results. Therefore, do not rely solely on the fabric name when selecting production materials.
2. Choose the Appropriate Polyester Content
If you use digital sublimation printing, choose fabric with a high polyester content. Sublimation ink can bond effectively with polyester fibers, producing sharp and more durable colors.
Adjust the fiber composition according to the product requirements so that both the print quality and fabric characteristics meet your desired standards.
3. Use White or Light-Colored Fabric
Choose white or light-colored fabric when using sublimation printing. A bright base color helps produce optimal print colors that are closer to the original design.
Conversely, a fabric base color that is too dark can affect the appearance of the print and prevent the design colors from appearing as expected.
4. Test Heat Resistance
Make sure the fabric can withstand high temperatures during the production process, especially when using a heat press machine. Conduct testing beforehand to determine how the fabric responds to temperature and pressure.
This testing helps prevent changes in shape, surface damage, or other issues that could reduce product quality.
5. Adjust Fabric Weight and Texture
Choose the fabric weight and texture based on the product’s function. Thicker fabric can provide a different structure compared with lightweight fabric, while fabric texture can affect comfort and appearance.
In addition to the fabric, adjust the sublimation ink, transfer paper, temperature, pressure, and heat press duration to ensure the entire process produces consistent products.
