A 101 to OASIS Super Absorbent Fibre

Super absorbent yarns are water-insoluble materials designed to absorb and retain large amounts of water or other liquids. Through a complicated matrix of fibre materials, super absorbent yarns prevent water ingress and penetration, making them ideal for a range of industrial applications. At Tex Tech, we manufacture our OASIS Super Absorbent Fibre (SAF) using a range of super absorbent yarns to protect cables and other electronic equipment from damaging moisture.


Swellable Yarn

Benefits of Super Absorbent Yarns

The primary benefit of super absorbent yarns is their water-blocking abilities. Upon contact with water, these yarns swell and form an impermeable barrier. This prevents access and dissipation of moisture throughout sensitive components such as cables and electrical equipment, protecting them against premature failure. Other benefits of super absorbent yarns include:

  • Cost-effective. Super absorbent yarns can be customized to fit the needs of a particular application. This negates the need for multiple water-blocking products, making it a more cost-effective option. Super absorbent yarns also feature lower installation costs compared to alternatives.
  • Clean. Compared to other water-blocking solutions, super absorbent yarns are cleaner and eliminate dusting issues that are common with powder-coated yarns.
  • Compact. Super absorbent yarns aren’t as bulky as other tape and yarn technologies, making them the ideal solution for vulnerable areas within cables and electrical equipment.
  • Temperature-resistant. Super absorbent yarns can be formulated to withstand the high temperatures that are often experienced during cable operation.

Tex Tech’s OASIS Super Absorbent Fibre

At Tex Tech, our OASIS yarns use super absorbent yarns to protect cables from water ingress. By minimizing water penetration, our water-blocking yarns prevent premature damage and cable failure. Our OASIS Super Absorbent Fibre works by absorbing moisture immediately and swelling to form a protective barrier, preventing more moisture from entering the cable or electrical component.

Tex Tech’s OASIS swellable yarns are made using >70% recycled fiber, are available from 500 denier to 270,000 denier, and come in a range of thicknesses to suit various needs. These yarns are commonly used throughout the power, data, and fibre optic cable industries for applications such as cross laying, watertight conductors, and fillers over or between multi-core cables. To ensure optimal performance, our yarns are designed to hold up on the most demanding production lines with a clean and efficient product build.

Specific advantages and properties of our OASIS Super Absorbent Fibre include:

  • Fast swell rate
  • High tenacity strength
  • Superior absorption capacity to block water ingress
  • Consistent performance
  • Cleaner and generates less dust

To meet the specifications and requirements of each customer, our OASIS Super Absorbent Fibre solutions are available in a range of sizes and diameters and come in long staple wrap spun or long staple ring spun styles.
