How do the material properties of Polyester Spandex Loose Knit Fabric affect its performance?

The core of Polyester Spandex Loose Knit Fabric popularity for its excellent performance lies in its material properties. Understanding these properties is essential to understanding the advantages and applications of this fabric.

1. Characteristics of Polyester
High Strength and Durability: Polyester (polyester fiber) is a synthetic fiber known for its high strength and durability. Polyester fiber has a high molecular crystal structure, which enables the fiber to withstand large stretching and pressure without breaking or deforming. Due to this high strength, after polyester fiber is made into fabric, it can effectively improve the durability of the fabric, making it suitable for clothing that needs frequent use and washing, such as sportswear and work clothes.

Heat Resistance: Polyester fiber has a high melting point, usually around 250°C. This makes polyester fabric have good heat resistance and can maintain its physical properties in high temperature environments. Whether it is high-temperature ironing or high-temperature washing, Polyester Spandex Loose Knit Fabric can maintain its form and performance and is not easy to melt or deform.

Good dimensional stability: The high crystallinity of polyester fiber not only gives it strength and durability, but also gives it good dimensional stability. This means that polyester fabrics are not easy to shrink or stretch during use and washing, and can maintain the original shape and size of the garment.

Anti-UV performance: Polyester fiber has strong anti-UV ability and is not easily destroyed by ultraviolet rays in sunlight. This makes Polyester Spandex Loose Knit Fabric suitable for the production of outdoor clothing and sportswear, and can still maintain its color and structure stability under long-term sun exposure.

2. Characteristics of spandex
High elasticity: Spandex (elastic fiber) is known for its excellent elasticity. It can be stretched to several times its original length and quickly return to its original length after the external force is removed. The high elasticity of spandex allows the fabric to maintain its shape and comfort when stretched and moving.

Softness: Spandex fiber has good softness, which makes the fabric very comfortable to touch and suitable for clothing that fits close to the skin, such as underwear, swimsuits and sportswear. Soft spandex fibers play a role in increasing comfort in fabrics, making the wearer feel relaxed and at ease.

3. Combination of polyester and spandex
The combination of polyester and spandex gives full play to the advantages of the two fibers to form a fabric with unique properties.

Balance of elasticity and strength: The high strength and durability of polyester combined with the high elasticity of spandex make Polyester Spandex Loose Knit Fabric have good elasticity and comfort while maintaining shape and structural stability. Whether it is stretching during exercise or activities in daily wear, the fabric can quickly return to its original form and is not easy to deform.

Enhanced durability: The durability of polyester fibers allows the fabric to maintain its performance after frequent use and washing. The elasticity and softness of spandex fibers enhance the wearing comfort of the fabric, making Polyester Spandex Loose Knit Fabric an ideal choice for making high-performance clothing.

Superior recovery: Due to the high elasticity of spandex fiber, the fabric can quickly return to its original shape after being subjected to external force. This feature makes the clothing less likely to become loose or wrinkled during wearing, maintaining a good appearance.
