PBT Technology

What is PBT Technology Fabric?

PBT (polybutylene terephthalate) fabric is a specialized polyester known for its stretch, quick-drying, and chlorine-resistant properties. This advanced PBT textile technology produces a performance PBT fabric with an ideal balance of flexibility and durability for sports applications. PBT technology fabric is engineered for high-performance clothing – making it a top choice for athletic apparel and swimwear that need long-lasting stretch and strength.

Benefits of PBT Stretch Fabric

• Chlorine Resistance: PBT fibers resist damage from chlorinated water, making chlorine resistant PBT fabric ideal for swimsuits and other pool-use garments.
• Durability & Longevity: PBT textiles are extremely tough, maintaining integrity through intense use and frequent washing. Garments made of this durable PBT sportswear material last significantly longer than those with standard elastane blends.
• Stretch & Recovery: PBT stretch fabric provides excellent elasticity and snap-back recovery, often retaining nearly 100% of its shape. It rivals spandex in stretch performance while offering far better chlorine tolerance.
• Quick-Drying: PBT is hydrophobic and dries rapidly when wet. Athletes benefit from gear that stays light and doesn’t remain waterlogged after swimming or washing.

Applications in Swimwear & Sportswear

PBT fabric is widely used in swimwear, competitive sportswear, and training apparel because it offers a combination of stretch and toughness. Competitive swimmers favor PBT race suits for their superior chlorine resistance and ability to maintain a tight fit over time.

Beyond the pool, PBT’s resilience makes it ideal for activewear that must endure rigorous training. From practice jerseys to compression shorts, PBT clothing fabric keeps its shape and performance after repeated use. Sportek International’s SP-PBT500 fabric (part of our PBT 500 fabric series) exemplifies advanced PBT tech, offering moisture management, water resistance, and chlorine-proof performance for rash guards and aquatic sports gear.

Frequently Asked Questions about PBT Fabric

What is PBT fabric used for?

PBT fabric is primarily used for performance apparel that requires stretch, durability, and chlorine resistance. Its most common applications are in swimwear (like competitive swimsuits) and high-performance sportswear (such as training gear and athletic uniforms). Many teams choose PBT-based clothing because it lasts longer under demanding conditions.

Is PBT fabric chlorine resistant?

Yes. PBT is highly chlorine-resistant, so it won’t degrade in pool water like ordinary spandex. Swimsuits made with PBT maintain their stretch and color even after dozens of uses, outlasting typical Lycra-blend suits.

Does PBT fabric stretch?

Yes. PBT material offers considerable stretch (though not as much as Lycra) with outstanding recovery. Once stretched, it springs back to shape reliably, so garments move with you without ever becoming baggy or losing their fit.
