T400 vs. Spandex Polyester Fabric: Comparing Advantages and Disadvantages

In the world of textiles, it’s essential to be aware of the different types of materials and their unique properties. Two widely used fibers in the industry are T400 and polyester. Despite some similarities, T400 fabric offers distinct advantages over polyester. In this article, we will delve into the unique characteristics of T400 fabric, understand how it differs from polyester, and explore its various applications.

What is T400 Fabric?

T400 is an innovative elastic composite fiber that does not contain spandex yet provides excellent elasticity. This revolutionary material addresses the challenges associated with spandex, such as difficulties in dyeing, excessive elasticity, intricate weaving processes, unstable fabric dimensions, and spandex aging during use.

400 fiber and it’s origin story

T400 materials were developed by INVISTA, a global leader in the production of high-performance fibers and polymers. This unique material was introduced in the early 2000s under the LYCRA® brand, known for its quality and innovative elastic fibers. T400 fabric was developed to provide an alternative to traditional spandex fibers while addressing the challenges associated with spandex, such as difficulties in dyeing, excessive elasticity, complex weaving processes, and spandex aging during use.

T400 fabric is created through a proprietary process called “multicomponent spinning,” which combines two or more polymer components into a single fiber. The resulting fiber has unique elastic properties and offers a range of benefits that make it an attractive choice for the textile industry. Some of the key features of T400 fabric include its relaxed, comfortable, and durable elasticity, excellent wrinkle resistance, moisture absorption and quick-drying capabilities, and good dimensional stability.

The origin story of T400 fabric began with the need to develop a material that combined the desirable properties of both spandex and polyester without their respective drawbacks. INVISTA’s innovative solution provided a new type of fiber that offers the benefits of spandex, such as elasticity and comfort, but with improved durability, ease of handling, and dyeing properties. Over the years, T400 fabric has gained popularity in various applications, including activewear, ready-to-wear clothing, and denim, due to its versatility and performance.

Characteristics of T400 Fabric

T400 fabric exhibits a range of desirable properties that make it stand out from other fibers, including:

  1. Relaxed Elasticity: T400 fabric offers comfortable, durable, and relaxed elasticity, making it suitable for various garments.
  2. Softness and Drape: The fabric is soft, has a pleasant stiffness, and drapes well, providing an elegant appearance.
  3. Smooth Surface and Wrinkle Resistance: T400 fabric has a smooth surface and resists wrinkling, ensuring garments maintain a polished look.
  4. Moisture Absorption and Quick Drying: The fabric’s ability to absorb moisture and dry quickly enhances comfort and provides a smooth hand feel.
  5. Dimensional Stability: T400 fabric boasts excellent dimensional stability, making it easy to handle and shape during garment production.

T400 fabric is available in various specifications, including DTY 50D/24F, 75D/24F, 75D/36F, 100D/36F, 150D/48F, 300D/144F, and 450D/216F.

Understanding Spandex Polyester Fabric

Spandex polyester fabric is a blend of spandex, a highly elastic synthetic fiber, and polyester, a synthetic material known as polyethylene terephthalate. This combination results in a fabric that possesses the desirable properties of both materials.

Characteristics of Spandex Polyester Fabric

Spandex polyester fabric offers a range of advantageous properties, including:

  1. Elasticity: The spandex content provides exceptional stretch and recovery, while the polyester adds strength and durability to the fabric.
  2. Resistance to Wrinkling: The polyester component contributes to the fabric’s wrinkle resistance, ensuring garments maintain a polished look.
  3. Strength and Abrasion Resistance: Polyester is known for its high strength and abrasion resistance, which enhances the durability of spandex polyester fabric.
  4. Colorfastness: The blend of spandex and polyester results in a fabric with excellent colorfastness, ensuring garments retain their vibrant hues even after multiple washes.

However, spandex polyester fabric has some limitations as well. Its moisture absorption and breathability are not as good as those of natural fibers, which can make it less comfortable to wear, particularly in hot or humid conditions. As a result, spandex polyester fabric is best suited for outerwear or activewear, where its elasticity and durability are most beneficial.

T400 Fabric is usually more expensive, why? Durability!

The main disadvantage of T400 fabric is its price. It’s typically more expensive. But why?

Both T400 fabric and spandex polyester fabric exhibit durability, but their individual properties result in some differences:

  1. Elasticity: T400 fabric offers excellent elasticity without the need for spandex, which can degrade over time and affect the fabric’s overall durability.
  2. Moisture Absorption and Quick Drying: T400 fabric has superior moisture absorption and quick-drying capabilities, which can contribute to its longevity by reducing the potential for odor or mildew growth.
  3. Dimensional Stability: T400 fabric has better dimensional stability than spandex polyester fabric, resulting in a more consistent shape and structure over time.

In conclusion, while both T400 fabric and spandex polyester fabric offer durability, T400 fabric may have a slight edge due to its inherent elasticity without spandex, superior moisture management, and better dimensional stability. However, the choice between the two materials ultimately depends on the specific requirements of the garment and its intended use.

Conclusion: Comparing T400 Fabric and Spandex Polyester Fabric

While both T400 fabric and spandex polyester fabric are synthetic materials with elastic properties, they exhibit some key differences:

  1. Spandex Content: T400 fabric does not contain spandex but still offers excellent elasticity, while spandex polyester fabric relies on the addition of spandex for its stretch and recovery properties.
  2. Moisture Absorption and Quick Drying: T400 fabric has better moisture absorption and quick-drying capabilities compared to spandex polyester fabric.
  3. Dimensional Stability: T400 fabric boasts superior dimensional stability, making it easier to handle and shape during garment production.
  4. Comfort: Due to its elasticity, softness, and moisture absorption, T400 fabric is generally more comfortable to wear than spandex polyester fabric.

T400 fabric, with its unique properties and advantages over polyester, is a versatile and innovative material that has found applications in a variety of garments. Its exceptional elasticity, wrinkle resistance, moisture absorption, and comfort make it an excellent choice for manufacturers and designers looking to create high-quality clothing with superior performance and aesthetic appeal.
