Strength and durability of Polyester Spandex Fabric

Polyester Spandex Fabric, also known as polyester spandex fabric, is a composite fabric that combines the advantages of polyester fiber and spandex. This fabric has been widely used in many fields such as clothing, sports equipment and medical supplies due to its excellent strength and durability.

Strength characteristics
1. High-strength foundation
Polyester fiber is one of the main components of Polyester Spandex Fabric and is known for its excellent strength. The breaking strength of polyester fiber can reach 0.5-0.9dN/tex in dry state (according to the data of the reference article), which is excellent compared with other synthetic fibers and natural fibers. High-strength polyester fiber provides a solid foundation for Polyester Spandex Fabric, making it not easy to break in daily use and repeated stretching.

2. Enhanced elasticity
The addition of spandex is another highlight of the strength characteristics of Polyester Spandex Fabric. Spandex is an elastic fiber that can be stretched 6-7 times and quickly return to its original state as the tension disappears. This excellent elasticity not only improves the comfort of the fabric, but also enhances the overall strength of the fabric to a certain extent. When the fabric is subjected to external force, the elasticity of spandex can absorb part of the impact force, thereby protecting the polyester fiber from damage.

3. Composite effect
The composite of polyester fiber and spandex is not a simple superposition, but a special spinning and weaving process that closely combines the two. This composite structure enables Polyester Spandex Fabric to have good elasticity and resilience while maintaining high strength. Whether it is stretched, twisted or compressed, the fabric can quickly return to its original form, showing extraordinary strength and stability.

Durability characteristics
1. Abrasion resistance
The wear resistance of Polyester Spandex Fabric is also commendable. Polyester fiber itself is a synthetic fiber with excellent wear resistance, and its wear resistance is second only to nylon (refer to article data). The addition of spandex does not weaken this characteristic, but further extends the service life of the fabric by improving the elasticity and resilience of the fabric. Whether it is daily wear or friction and wear during exercise, Polyester Spandex Fabric can maintain a good appearance and performance.

2. Lightfastness
Polyester fiber also has good lightfastness and can keep the color bright and stable under long-term light exposure. Although spandex is more sensitive to light, in Polyester Spandex Fabric, due to the dominance of polyester fiber, the overall lightfastness of the fabric is still excellent. This allows the fabric to remain beautiful and durable for a long time in outdoor environments.

3. Chemical corrosion resistance
Polyester Spandex Fabric also has a certain degree of chemical corrosion resistance. Polyester fiber can resist the erosion of a variety of chemicals, including bleach, oxidants, hydrocarbons, ketones and petroleum products (refer to article data). Although spandex is more sensitive to certain chemicals, under normal use and maintenance, Polyester Spandex Fabric can still maintain good durability.

4. Elastic durability
The elastic durability of spandex is also an important part of the durability of Polyester Spandex Fabric. Compared with other elastic fibers, spandex has an extremely high elastic recovery rate, which can maintain the elasticity and shape stability of the fabric for a long time. This means that even after multiple washings and wearings, Polyester Spandex Fabric can still maintain good elasticity and comfort.

Polyester Spandex Fabric has been widely used in many fields due to its high strength and excellent durability. Whether it is making high-performance sportswear, tights or medical supplies, Polyester Spandex Fabric can provide reliable performance guarantee and comfortable wearing experience.
