SAF™ Water-Blocking Technology

SAF™ – a soft superabsorbent fibre – is the key component in all of our water-blocking yarns and tapes. They absorb water and saline rapidly with excellent retention levels and the SAF™ content does not shed or dust when they are being cut and spliced for use. 

Introducing a SAF™ spun yarn or low basis weight SAF™ fabric within telecommunication or power cables can help protect against incoming water by absorbing water at the point of damage. Upon contact with the water, the yarn or fabric will swell and form an impermeable barrier.

Yarn and Fabric selection will be influenced by the final end use. An experienced development team are on hand to offer advice and help with initial yarn selection for trials. Where possible, bespoke products will be designed and manufactured to meet specific requirements.

SAF™ Superabsorbent Yarns

52mm and 80mm SAF™ fibres can be spun with other staple fibres to produce these high performance swellable yarns. The denier, decitex, absorption rate and ultimate swell height can meet required specifications by altering the SAF™ grade and fibre blend.

SAF™ can be processed by all well-known staple fibre spinning systems. Typically, SAF™ would be blended with other synthetic fibres such as polyester, nylon, cellulose and aramids. These fibre blends are normally processed using the cotton and semi-worsted systems.

Superabsorbent SAF™ Yarns are supplied on bobbins, which can be sized to suit manufacturing requirements, they are lightweight, easy to onward process. A standard range of yarns are already available and others can be manufactured to meet specific requirements.

Current yarns range from 250 – 26000 denier. Please click here to view range

SAF™ Superabsorbent Fabrics

SAF™ Thermo-Carded fabrics are cost-effective, thinner materials that provide high levels of absorbency. They are lightweight, conformable, and can be manufactured with a number of layers. This makes them ideal for water-blocking applications that require performance without the bulk.

The fabrics range from 20-80gsm and are typically a blend of SAF™ and other synthetic fibres.

Water-Blocking – Why Select a SAF™-based Technology?

Introducing a SAF™ spun yarns and/or fabric provides many benefits along the supply chain:

  • Improved super absorbent distribution throughout the yarn or fabric thus reducing weak spots
  • Rapid absorption at point of damage
  • Control of absorption rate and swell via SAF™ grade and fibre blend
  • Potential combination with cable strengthening materials
  • Easier handling/installation due to reduced shedding/dusting
