As a professional swimwear manufacturer established in 2008, Unijoy understands the importance of high-quality fabrics in swimwear production. The fabric not only affects the appearance and feel of swimwear but also its performance and durability. While common swimwear fabrics like Nylon, Polyester, and Spandex are widely used, technological advancements have introduced innovative materials such as PBT (polybutylene terephthalate), enhancing swimwear’s properties. Let’s delve into the properties and benefits of PBT fabric.
What is PBT Fabric?
PBT (polybutylene terephthalate) is a synthetic textile belonging to the polyester family, similar to PET fabrics. It boasts exceptional durability, chemical resistance and fade resistance, making it ideal for high-quality swimwear and beachwear.
Properties of PBT Fabric
Pros:
Durability
PBT fabric is exceptionally durable, maintaining its shape, elasticity, and dimensional stability are not affected by humidity, even after repeated wear and wash. It resists tearing, stretching, and abrasion, ensuring a long lifespan and a comfortable fit for customized swimwear made from PBT.
Chemical Resistance
PBT fabric has excellent chemical resistance, including acid resistance, alkali resistance and chlorine resistance. PBT fabric withstands exposure to swimming pools’ chlorinated water without damage or fading, enhancing the durability and longevity of custom made swimwear.
Moisture Resistance
PBT fabric has good moisture resistance, low water absorption (only about 0.4%) and quick-drying capabilities. The moisture resistance of PBT fabric swimwear helps keep the wearer dry and comfortable during activities.
Dyeing Property
PBT fabric has excellent dye-ability, producing bright colours with high colour fastness and chlorine resistance.
Cons:
Relatively High Cost
As a new type of synthetic fibre material, PBT fabric has a higher production cost, impacting bulk swimsuit production cost control which is an important consideration in swimwear manufacturing.
Sensitive to High Temperature
PBT fabric is sensitive to high temperatures, with heat resistance slightly lower than PET and PA fabrics.
PBT Fabric in Swimwear Manufacturing
PBT fabric is excellent for swimwear, beachwear, and other sportswear due to its durability, chlorine resistance, and quick-drying properties. It is often blended with polyester to create high-performance and chlorine-resistant swimwear. For swimwear brands seeking high-quality and high-performance fabrics, PBT offers a valuable option.
