What is "Polyolefin Fibre" - Definition & Explanation
Polyolefin Fibre

Polyolefin fiber is a synthetic fiber derived from polyolefin polymers, which are high molecular weight hydrocarbon polymers. It is a versatile and widely used material in the textile industry due to its exceptional properties and performance. Polyolefin fibers are known for their durability, lightweight nature, moisture resistance, and thermal stability.

Polyolefin fibers are manufactured through a process called melt spinning, where the polymer is melted and extruded through spinnerets to form continuous filaments. These filaments are then processed into various forms such as staple fibers, filaments, or films, depending on the intended application.

Types of Polyolefin Fiber

There are two main types of polyolefin fiber commonly used in the textile industry:

  1. Polypropylene (PP) Fiber: Polypropylene fiber is the most widely used type of polyolefin fiber. It is known for its excellent moisture-wicking properties, quick-drying nature, and resistance to mildew and bacteria. Polypropylene fibers are commonly used in activewear, sports apparel, outdoor clothing, and upholstery fabrics.
  2. Polyethylene (PE) Fiber: Polyethylene fiber is another type of polyolefin fiber with excellent tensile strength, chemical resistance, and UV stability. It is commonly used in applications such as geotextiles, protective clothing, and ropes.

Top International Users and Manufacturers

Several international brands and manufacturers utilize polyolefin fiber in their textile products. Here are some of the top users and manufacturers:

  1. Patagonia: Patagonia, a well-known outdoor apparel brand, incorporates polyolefin fibers in their performance-driven clothing, ensuring durability, moisture management, and lightweight comfort for outdoor enthusiasts.
  2. The North Face: The North Face utilizes polyolefin fiber in their activewear and outdoor gear, offering high-performance products that provide insulation, moisture control, and protection from the elements.
  3. Under Armour: Under Armour, a leading athletic apparel brand, utilizes polyolefin fibers in their sports clothing, providing moisture-wicking properties and thermal regulation for enhanced performance and comfort.
  4. 3M: 3M, a global diversified technology company, manufactures polyolefin-based materials used in various industries, including textiles. Their products include protective clothing, adhesives, and films.
  5. DuPont: DuPont, a multinational chemical company, produces polyolefin fibers under the brand name "Tyvek," which is widely used in protective apparel, construction materials, and industrial applications.

Tips in Handling Polyolefin Fiber

When working with polyolefin fiber, it is important to consider the following tips:

  • Temperature Control: Polyolefin fibers have a low melting point, so it is crucial to avoid high temperatures during processing or ironing to prevent damage to the fabric.
  • Washing and Care: Polyolefin fibers are generally easy to care for and can withstand regular machine washing. However, it is recommended to follow the garment's specific care instructions to maintain its properties and longevity.
  • Compatibility: Polyolefin fibers can be blended with other fibers to enhance specific properties. It is important to consider the compatibility of the fibers and follow appropriate blending ratios to achieve the desired performance.


Polyolefin fiber is a versatile and widely used synthetic fiber in the textile industry. With its exceptional properties such as durability, moisture resistance, and thermal stability, it finds application in various sectors ranging from activewear and outdoor clothing to protective apparel and industrial materials. Prominent brands and manufacturers like Patagonia, The North Face, and Under Armour utilize polyolefin fiber in their products, ensuring high-performance textiles that cater to the needs of advanced users. When handling polyolefin fiber, it is essential to consider temperature control, proper washing and care methods, and blending compatibility to optimize its properties. The continuous advancements in polyolefin fiber technology continue to enhance its performance and expand its applications, making it a valuable material in the textile industry.

Polyolefin Fibre
A fibre made from a synthetic linear polymer obtained by polymerising an unsaturated hydrocarbon (e.g. ethylene CH?-CH? or propylene CH? = CH-CH3) to give a linear saturated hydrocarbon. (See also polyethylene fibre and polypropylene fibre).
