Understanding Polyester and Lycra
What is Polyester?
Polyester is a synthetic fabric made from polymer, known for its durability, resistance to wrinkles, and quick drying capabilities. This fiber is widely used in various applications, from clothing to home furnishings. Polyester can be treated to become waterproof, making it an excellent choice for outdoor gear and activewear.
What is Lycra?
Lycra, known as spandex or elastane, is a synthetic fiber that is renowned for its exceptional stretch and recovery capabilities. It can expand up to 5-8 times its original size and return to its shape. While Lycra itself is not waterproof, it can be blended with polyester to enhance its flexibility and comfort in waterproof applications.
The Science of Waterproofing
How Does Waterproofing Work?
Waterproof fabrics are engineered to resist water penetration. A common method involves applying a durable water repellent (DWR) coating to the fabric. This coating helps water bead up and roll off, keeping the fabric dry. The hydrostatic head measurement, which gauges how much water pressure a fabric can withstand, is a key metric in determining waterproof capability.
Differences Between Waterproof, Water-Resistant, and Water-Repellent
- Waterproof: Completely prevents water from passing through, often used in heavy-duty outdoor gear.
- Water-Resistant: Offers some protection against water but is not fully impermeable.
- Water-Repellent: Treated to resist water but can still absorb moisture over time.
Applications of Polyester and Lycra Fabrics
Activewear
Polyester is widely used in activewear because of its moisture-wicking properties and durability. Brands like Wazoodle offer unique polyester blends that enhance flexibility and comfort, making them perfect for sports and everyday wear.
Swimwear
Lycra is the go-to fabric for swimwear due to its ability to stretch and fit snugly without losing shape. The combination of Lycra with waterproof polyester creates swimwear that not only looks good but also performs well in water.
Outdoor Gear
Waterproof polyester is essential in manufacturing outdoor gear like jackets, tents, and backpacks. Companies like Deekon Textile specialize in creating high-quality polyester Lycra waterproof fabrics that can withstand harsh weather conditions.

FAQ
What are the benefits of using polyester in waterproof fabrics?
Polyester offers excellent durability, moisture-wicking properties, and can be treated to become waterproof, making it suitable for outdoor and activewear.
Is Lycra waterproof?
No, Lycra itself is not waterproof; however, it can be blended with waterproof materials like polyester to enhance its properties for swimwear and activewear.
How can I tell if a fabric is waterproof?
You can check the hydrostatic head rating, which indicates how much water pressure the fabric can withstand before leaking. A rating of 10,000 mm or higher is generally considered waterproof.
What types of clothing typically use Lycra?
Lycra is commonly used in swimwear, activewear, and form-fitting garments due to its stretch and recovery properties.
Can polyester be recycled?
Yes, polyester can be recycled, and many brands are now focusing on creating sustainable fabrics from recycled polyester.
What is the difference between water-resistant and waterproof?
Water-resistant fabrics can repel water to some extent but may not withstand heavy rain, while waterproof fabrics are designed to completely block water penetration.
Which fabric is better for activewear, polyester or Lycra?
Both fabrics have their advantages. Polyester is great for moisture management and durability, while Lycra provides stretch and comfort. A blend of both often offers the best performance.
How should I care for polyester and Lycra fabrics?
It’s best to follow the care label instructions. Generally, machine wash in cold water and avoid bleach. Air dry or tumble dry on low heat for best results.
What is Elasterell-P?
Elasterell-P is a type of elastomultiester polyester fiber that offers spandex-like stretch while being free of traditional spandex, making it suitable for various stretch applications.
Are there any environmental concerns regarding polyester and Lycra?
Yes, both fabrics are synthetic and can contribute to microplastic pollution. However, using recycled materials and sustainable practices can mitigate some of these environmental impacts.
