Aramid Fiber

Aramid is a type of synthetic fiber that is renowned for its exceptional strength and heat-resistant properties. It is widely used in various industries, including textiles, due to its exceptional performance characteristics. This article provides a detailed exploration of aramid in textile, including its history, types, tips for handling, and profiles of top international users and manufacturers.

History and Origin

The history of aramid dates back to the early 1960s when scientists at DuPont, a multinational chemical company, developed a groundbreaking synthetic fiber called Nomex. Nomex, a type of aramid, was initially designed for use in protective apparel for firefighters due to its remarkable flame resistance and thermal stability. Later, another aramid fiber known as Kevlar was introduced by DuPont, which found applications in various industries, including aerospace, military, and automotive.

Types of Aramid

There are two primary types of aramid fibers used in textiles:

  1. Nomex: Nomex is a meta-aramid fiber known for its exceptional thermal stability and flame resistance. It is commonly used in protective apparel, such as firefighter suits, industrial workwear, and racing suits.
  2. Kevlar: Kevlar is a para-aramid fiber that is renowned for its high tensile strength, excellent cut and abrasion resistance, and low weight. It finds applications in a wide range of industries, including ballistic protection, reinforcement for composites, and high-performance sports equipment.

Tips for Handling Aramid

When working with aramid textiles, it is important to keep the following tips in mind:

  • Protective Measures: Aramid fibers can cause skin irritation, so it is recommended to wear gloves and protective clothing when handling them.
  • Sharp Objects: While aramid fibers are highly durable, they can be susceptible to damage from sharp objects. Care should be taken to avoid cutting or puncturing the fabric.
  • Heat Sensitivity: Although aramid fibers exhibit excellent heat resistance, prolonged exposure to high temperatures can cause degradation. It is essential to follow recommended temperature guidelines during processing and use.
  • Cleaning and Care: Aramid fabrics are typically easy to clean and maintain. However, it is advisable to follow the manufacturer's instructions for proper care to preserve the fabric's performance and longevity.

Top International Users and Manufacturers

Several international brands are known for their utilization and production of aramid textiles. Here are some of the top users and manufacturers:

  1. DuPont: DuPont is a renowned multinational chemical company that played a crucial role in the development and commercialization of aramid fibers. They are the creators of Nomex and Kevlar, and their products are widely used in industries such as aerospace, defense, and automotive.
  2. Teijin: Teijin is a leading Japanese chemical company that produces aramid fibers under the brand name Twaron. Their aramid products find applications in various industries, including ballistic protection, reinforcement for composites, and heat-resistant fabrics.
  3. Honeywell: Honeywell is a multinational conglomerate that manufactures a range of advanced materials, including aramid fibers. Their aramid product, known as Spectra, is widely used in high-performance applications such as body armor, ropes, and cut-resistant gloves.
  4. Taekwang: Taekwang is a South Korean company specializing in the production of aramid fibers under the brand name TaeKwang Ace. Their aramid fibers are utilized in various industries, including protective apparel, reinforcement for composites, and friction materials.
  5. Hyosung: Hyosung, a South Korean multinational conglomerate, is a major producer of aramid fibers under the brand name Creora. Their aramid fibers are widely used in diverse applications, including protective clothing, automotive reinforcements, and ropes.

Conclusion

Aramid fibers, such as Nomex and Kevlar, have revolutionized the textile industry with their exceptional strength, heat resistance, and durability. These fibers find extensive applications in various sectors, ranging from protective apparel to aerospace and automotive industries. Understanding the history, types, and proper handling of aramid is crucial to harnessing their full potential and ensuring the development of high-performance textile products.


Aramid
A manufactured fiber in which the fiber-forming substance is a long chain of synthetic polyamide in which at least 85% of the amide linkages are attached directly to two aromatic rings. Aramid fabrics are very strong and are resistant to high temperatures and extreme external forces. Aramid fabrics are used in thermally protective clothing; (i.e. coveralls, jackets, gloves, shirts, pants). U.S. FTC Definition: A manufactured fiber in which the fiber-forming substance is a long-chain synthetic polyamide in that is at least 85% of the amide linkages are attached directly to two aromatic rings.
Aramid Fiber
The generic name for fibres composed of synthetic linear macromolecules that have in the chain recurring amide groups, at least 85% of which are joined directly to two aromatic rings and in which imide groups may be substituted for up to 50% of the amide groups.

Aramid Fiber
Aramid fiber (1961) is a fire-resistant and strong synthetic fiber. It is used in aerospace and military applications, for "bullet-proof" body armor fabric, and as an asbestos substitute. The term is a shortened form of "aromatic polyamide".
