Polyester Fiber for Airbag and Preparation Method Thereof

Polyester fibers with unique properties have been developed by Kolon Industries, Inc., as evidenced by the publication of WO/2011/074920 on June 23. The invention, which was filed on December 17, 2010, under PCT/KR2010/009088, has been designed to provide superior mechanical properties, including high strength, high elongation, and high shrinkage. These properties allow the polyester fiber to decrease stiffness remarkably, securing better packing property, dimensional stability, and air-tight effect when used in airbag fabrics.

Key Takeaways:

• The polyester fiber invented by Kolon Industries, Inc. exhibits exceptional properties, including an elongation of 0.4% or less at 1.0 g/d, an elongation of 4.0% or less at 4.0 g/d, and an elongation of 7.0% or less at 7.0 g/d.
• The fiber's high strength, high elongation, and high shrinkage provide superior mechanical properties, making it suitable for use in airbag fabrics.
• The polyester fiber's unique properties allow it to decrease stiffness remarkably, ensuring better packing property, dimensional stability, and air-tight effect.
• The preparation method for the polyester fiber is also part of the invention, allowing for the creation of high-quality airbag fabrics.
• The patent application number is PCT/KR2010/009088, and the publication number is WO/2011/074920.
• The invention was filed on December 17, 2010, and published on June 23.
