About the Products

  • Polyester yarn for seatbelts
    Polyester yarn for seatbelts

    Our polyester yarn for seat belts has superb quality such as strict appearance management, excellent abrasion resistance, and dyeability, and is produced diversely including low denier yarn and black spun dyed yarn. Our product is recognized for its quality and technology and is supplied to the world’s leading companies.

    Airbag Yarn
    PET ㅣ Nylon-66

    Our airbag yarn is “ultra-tensile” to protect the human body even in high explosives. It also has “high elongation” that withstands force and expansion from an explosion and outstanding “thermal resistance” that blocks high-temperature heat.

    Ultra-tensile polyester and nylon 66 yarns are used for airbags as high tensile strength is required. The thickness and tensile strength of fabric can be adjusted depending on the size, shape, and use of airbags.

    It is important for yarns to comply with international quality certification standards to ensure quality and safety. Hyosung Advanced Materials produces the best airbag yarns based on our long-standing trust with automotive and auto parts companies. In response to customers’ demands for low cost, we developed the first PET yarn for airbags in Korea based on our constant research and development and yarn production expertise. We supply them to replace nylon 66 yarn for airbags.


  • For seatbelts
    It is used in all types of seatbelts from compact cars to large trucks and plays a crucial role in the safety of passengers in case of an accident.
  • For airbags
    It is used to make airbags to prevent injuries from falls in vehicles as well as bicycles and motorcycles and to protect riders against the impact of accidents.

    PET ㅣ Nylon-66

    Polyester and nylon 66 yarns have excellent properties of outstanding durability, resilience, and drying quickly.

    Polyester is mainly used in clothing and bedding for being light, soft, and comfortable on the skin. It is also used to make various bags.

    Nylon 66 is often used in sporting goods as it is strong against friction and has excellent durability due to its high tensile strength.

    Hyosung Advanced Materials produces various denier yarns to cover numerous products including dope dyed yarns. We are the only company producing both polyester and nylon 66 yarns.


  • Shoes
    Because they dry fast and are resistant to humidity, polyester and nylon 66 are great materials to maintain the durability of shoes. They are used in inner and outer fabric and shoelaces for athletic shoes or sneakers. Nylon 66 is particularly suitable for outdoor shoes such as tracking or hiking shoes as it has lightweight and superb thermal resistance properties.
  • Clothing
    PET ㅣ Nylon-66
    Polyester is often used to manufacture sportswear, raincoat, beachwear, t-shirts, sweaters, and jackets. Polyester is appropriate for sports and active activities due to its high durability and quick drying characteristics.

    Nylon 66 is used in various products including casual clothing, luxury clothing, sportswear, and accessories. It is especially used often in clothes or activewear that may have strong friction since it has excellent durability and abrasion resistance. Its lightweight and thermal resistance makes it also suitable for winter coats or outdoor clothing.
  • Furniture
    Polyester and nylon 66 are used in fabrics for sofas, chairs, and benches. They are also used as filling material for cushions and mattresses. They could be used in the legs and armrests of furniture as they are lightweight and have excellent thermal resistance.
  • Camping gear
    Polyester yarn is used to make camping gear such as tents, sleeping bags, and backpacks. Nylon 66 is used to make vinyl tapes and carriers.

The only manufacturer of
both nylon and polyester
in the world




    Hyosung Advanced Materials entered the high-functional industrial yarn in 1985. We presented nylon 66 airbag yarn for the first time in Korea and developed a nylon 66 yarn for high-tensile sewing to be used extensively in clothing and shoes.

    This wasn’t enough for Hyosung Advanced Materials which successfully developed the polyester yarn based on the yarn production know-how.

    This allowed us to become the only company in the world capable of producing both nylon and polyester yarn.
