High Extension Sewing Thread

High Extension Sewing Thread, an advanced sewing thread composed of PBT yarn, boasts superior extensibility, exceptional seam strength, and excellent sewing performance. Its elongation rate ranges from 30% to 60%, markedly surpassing that of conventional sewing threads with identical specifications. With its ability to produce highly stretchable seams on elastic fabric, it serves as a viable replacement for spandex thread.

Feature

High Elasticity: PBT threads have a high level of elasticity, allowing them to stretch significantly without breaking. This makes them excellent for applications that require a degree of flexibility and stretch.
Good Recovery: In addition to being able to stretch, PBT threads also have a good recovery, meaning they return to their original length after being stretched. This helps prevent deformation in sewn items over time.
Durability: Like other polyester materials, PBT is resistant to wear and tear, making it highly durable for long-lasting applications.
Chemical Resistance: PBT threads are resistant to many common chemicals, making them suitable for use in a variety of environments.
Heat Resistance: PBT has a good resistance to heat, which means it can withstand high-temperature environments and laundering processes without degrading.

Application

Athletic Apparel: Given its high elasticity and good recovery, PBT thread is commonly used in the manufacturing of sportswear and activewear, where garments need to stretch and move with the wearer.
Undergarments and Swimwear: PBT thread is ideal for sewing undergarments and swimwear due to its ability to stretch and return to its original shape. It's also resistant to chlorine and saltwater, which makes it suitable for swimwear.
Automotive Applications: In the automotive industry, PBT thread can be used for sewing car seats and interior components that require durability and a certain degree of stretch.
Home Textiles: Items like upholstery, curtains, and other home textiles can benefit from the durability and elasticity of PBT thread.
Medical Applications: PBT thread can be used in medical textiles that require elasticity, such as compression garments and bandages.
