Cotton and polyester are two distinct types of fabrics commonly used in the textile industry. Cotton is a natural fiber derived from the seedpod of the cotton plant, known for its breathability, absorbency, and comfort against the skin. In contrast, polyester is a synthetic fiber made from petroleum-based polymers, prized for its durability, resistance to wrinkles, and quick-drying properties. While cotton is favored for its softness and suitability in warm weather, polyester excels in terms of durability and easy maintenance. Both fabrics serve various purposes and can be blended to combine their unique qualities.
Cotton is a soft, fluffy natural fiber that grows in protective cases, called bolls, around the seeds of cotton plants (genus Gossypium). The fiber is almost pure cellulose. Under natural conditions, the cotton bolls will increase the dispersal of the seeds.
Cotton is one of the most widely used and important natural fibers in the world. It has been cultivated and used for thousands of years, with evidence of cotton cultivation dating back to ancient civilizations in India, China, and the Americas.
The primary use of cotton is in the textile industry, where it is spun into yarn or thread and used to make a wide range of products, including clothing, bed sheets, towels, and more. Cotton is valued for its breathability, absorbency, and comfort, making it a popular choice for clothing in various climates.
Cotton is also used in non-textile applications, such as in the production of paper, as a filler in some plastics, and in medical products like bandages and swabs.

Polyester
Polyester is a synthetic fiber made from a type of polymer called polyethylene terephthalate (PET). It is one of the most widely used synthetic fibers in the world due to its durability, versatility, and affordability. Here’s an overview of how polyester is made:
Raw Materials:
The primary raw material used in making polyester is petroleum, from which the basic building blocks of the polymer are derived.
The main chemical used in polyester production is ethylene, which is obtained from petroleum.
Polymerization:
The first step in making polyester involves a chemical reaction called polymerization. This process combines ethylene glycol (a colorless, odorless liquid alcohol) and terephthalic acid (or dimethyl terephthalate), which are the two main monomers used in polyester production.
The reaction produces a long chain of repeating units, creating a polymer known as polyethylene terephthalate (PET). This PET polymer forms the basis of polyester.
Extrusion:
The PET polymer is then melted and forced through tiny holes in a device called a spinneret to form long, continuous fibers. This process is known as extrusion.
Drawing and Cooling:
The extruded fibers are then cooled and stretched, a process known as drawing. This aligns the polymer chains and increases the strength and elasticity of the fibers.
Cutting and Texturizing:
After drawing, the fibers are cut into shorter lengths, which can then be spun into yarns.
Depending on the desired final product, the yarns can undergo additional processes like texturizing to give them specific textures or appearances.
Weaving or Knitting:
The yarns are then woven or knitted together to create fabrics. These fabrics can be used for a wide range of applications, including clothing, upholstery, bedding, and more.
Finishing:
The finished polyester fabrics may go through various finishing processes depending on their intended use. This can include treatments to enhance qualities like softness, wrinkle-resistance, water repellency, or fire resistance.
It’s worth noting that polyester can also be blended with other fibers like cotton, wool, or nylon to combine the properties of different materials. These blends can offer unique combinations of comfort, durability, and performance.
Overall, polyester is valued for its durability, resistance to wrinkles and abrasion, and its ability to retain its shape and color over time. However, it’s important to be aware that polyester is derived from petroleum, which is a non-renewable resource, and its production has environmental impacts associated with the extraction and refining of crude oil.
Clothes
Cotton and polyester are two popular materials used for underwear, and they each have their own set of advantages and disadvantages. Here’s a comparison between the two:
Cotton Underwear:
