Polyester and cotton are two of the most common and widely used fabrics in the world. These materials are characterized by their own qualities, and thus can be used for a variety of uses, from fashion and household furniture to industrial and outdoor applications. We need to be clear on the difference between polyester and cotton so we can make the right choice regarding durability, comfort, maintenance, and environmental sustainability.
In this article, we take an in-depth look at the polyester vs. cotton, its composition, key features, uses, and pros and cons. Eventually, you’ll know exactly which fabric works best for you.
1. Composition and Origin
a. Polyester
Polyester is a synthetic fiber that is produced from petroleum products by a chemical process called polymerization. In this process, raw materials such as ethylene glycol and terephthalic acid are fused into long chains of polymers, which are then melted, spun into fibers and woven into fabric. Polyester’s plethora of uses has made it a ubiquitous material in fashion as well as the construction industry.
Common types of polyester include:
PET (Polyethylene Terephthalate): The most common polyester material, widely used in clothing, household textiles, and even plastic.
PCDT (Poly-1,4-Cyclohexylene-Dimethylene Terephthalate): An elastinised version of polyester, widely used for upholstery and heavy-duty textiles.
Microfiber Polyester: It is made from ultra-fine fibers that has a comfortable feel and is used in high-end clothing, cleaning cloths, and sports wear.
Recycled Polyester (rPET): Contains recycled plastics (from bottles) that are a more environmentally friendly alternative to virgin polyester.
b. Cotton
Cotton is a plant fibre that is produced from the seed of the cotton plant (Gossypium). Once the fibres are detached from the seeds, they are spun into yarn and sewn into clothing. This has been happening for millennia and cotton remains one of the most commonly used textiles for its softness and breathability.
Different types of cotton include:
Egyptian Cotton: The long fibres, extra softness, and luxury feel of Egyptian cotton is commonly used in high-end bedding and clothing.
Pima Cotton: Like Egyptian cotton, which is cultivated primarily in the United States, this cotton is known for its toughness and silky texture.
Organic Cotton: Grown without artificial pesticides or fertilisers and thus more sustainable and environmentally friendly.
Normal Cotton: The most widely used variety, used in casual wear, household fabrics, and many household products.
2. Key Properties Comparison
a. Durability
Polyester:
Polyester is extremely durable and resistant to abrasion, stretch, and shrinkage. It has an artificial construction, which gives it high tensile strength, which prevents it from cracking and deteriorating over time. It’s also resistant to extremes such as direct sunlight and washing.
Cotton:
Cotton has moderate durability but is soft and more prone to wear. While cotton textiles may serve for years, they deteriorate over the course of repeated washing, particularly when wetted with aggressive detergents or at high temperatures.
Winner: Polyester is stronger and lasts longer than cotton, and works well in garments that need to withstand high loads, like sportswear and camping equipment.
b. Moisture-Wicking and Absorbency
Polyester:
Polyester repels and holds water, thereby removing water. Because it wicks moisture away from the skin, it evaporates quickly. This property has made polyester the perfect fabric for activewear and sports apparel.
Cotton:
Cotton is very abrasive, holding up to 27 times its weight in water. Although this makes it breathable during dry climates, it does keep moisture in and can take a while to dry, so in moist or wet climates it may be uncomfortable.
Winner:
Polyester is more moisture-wicking and quick-drying than cotton and is better for sporting and outdoor use.
c. Comfort and Breathability
Polyester:
Polyester is breathable, but the synthetic fibers tend to retain heat and moisture, so it’s not as breathable as natural materials. Although newer polyester blends and microfibers make it more breathable, it still might not be comfortable in hot or humid environments.
Cotton:
Cotton is known for its elasticity, breathability, and warmth. Its natural fibers are breathable, making it ideal for warmer climates and sensitive skin. Cotton, too, works at different temperatures – you can keep yourself cool during summer and warm during winter.
Winner: Cotton is more comfortable and breathable than polyester, particularly when it comes to daily use and delicate skin.
d. Wrinkle Resistance
Polyester:
Polyester naturally does not wrinkle, so it does not require ironing to keep its shape and texture. That makes it an excellent option for travel clothes, uniforms, and clothes that must be kept clean.
Cotton:
Cotton is very easily rolled up and must be ironed to keep it neat. Yet combining cotton and polyester will improve wrinkle resistance.
Winner: Polyester is more wrinkle resistant and easy to care for than cotton.
e. Shrinkage and Stretching
Polyester:
Polyester does not shrink or stretch and keeps its original size and shape even after repeated washes.
Cotton:
Cotton can shrink and stretch due to high temperatures during washing and drying. Pre-shrunk cotton or a mix of synthetic fibres can reduce this.
Winner: Polyester doesn’t move, shrink, or stretch like cotton.
f. Maintenance and Care
Polyester:
Polyester is easy to maintain, washable in the machine, and quick-drying. It is stain-resistant, fade-resistant, and resorbent, making it a useful fabric for an active lifestyle.
Cotton:
Cotton needs special attention while washing to avoid shrinkage, fading and injury. It’s slower to dry and can even require ironing to keep its shape.
Champion: Polyester is easier to wash and easier to wear everyday.
g. Environmental Impact
Polyester:
Polyester is made from fossil fuels, and it cannot be biodegraded, leading to long-term environmental issues. But the increasing availability of recycled polyester (rPET) provides a cleaner alternative, recycling plastic waste and eliminating virgin content.
Cotton:
Cotton is a natural and biodegradable fiber, so its disposal is less of an issue. Yet traditional cotton cultivation entails massive uses of water, land and pesticides that can have detrimental effects on the environment. Organic cotton is the more environmentally friendly alternative (though usually more costly).
Winner: While cotton is biodegradable, recycled polyester (rPET) offers a more environmentally friendly choice in the synthetic fiber market.
3. Applications and Uses
a. Polyester Applications
Polyester, a petroleum-based synthetic fibre, has excellent durability, moisture-wicking properties, and resistance to shrinkage, stretching, and discoloration.
