Polyester elastic fabric and spandex (also known as Lycra or elastane) are both popular choices for elastic fabrics, but they have some differences in terms of properties, performance, and applications:
Material Composition:
Polyester elastic fabric is primarily made of polyester fibers, which are synthetic fibers known for their durability, resistance to wrinkles, and ease of care.
Spandex is made of a polyurethane-based synthetic fiber, which is highly elastic and known for its exceptional stretchiness and recovery properties.
Stretch and Recovery:
Spandex has a much higher elasticity compared to polyester elastic fabric. Spandex can typically stretch up to 5 to 8 times its original length and return to its original shape, while
polyester elastic fabric has a more limited stretch and recovery.
Polyester elastic fabric still offers some degree of stretch, but it may not have the same level of elasticity and recovery as spandex.
Comfort and Fit:
Spandex provides a snug and comfortable fit due to its high elasticity, making it a popular choice for activewear, swimwear, and tight-fitting garments.
Polyester elastic fabric may offer less stretch and may not conform to the body as closely as spandex, but it still provides some flexibility and comfort.
Durability and Maintenance:
Polyester elastic fabric tends to be more durable and resistant to abrasion compared to spandex.
Spandex fibers can degrade over time with exposure to heat, chlorine, and certain chemicals, whereas polyester fibers are more resilient.
Applications:
Spandex is widely used in athletic wear, compression garments, swimwear, and other tight-fitting apparel where stretch and recovery are crucial.
Polyester elastic fabric is commonly used in applications where moderate elasticity and durability are needed, such as casual clothing, outerwear, linings, and certain types of activewear.
Cost:
Spandex is generally more expensive than polyester elastic fabric due to its higher elasticity and performance characteristics.
Polyester elastic fabric tends to be more budget-friendly while still offering some stretch and flexibility.
