Absorbent Yarns for Cable Water Blocking

High Performing Absorbent Spun Yarns.

Our water swellable Superabsorbent Yarns are commonly a blend of our long staple SAF™ Fibres and polyester. Other synthetic fibres such as nylon, cellulose and aramids can be used as alternatives, or in addition, to add strength and/or functionality. Upon exposure to aqueous fluid the yarns absorb rapidly.

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

Small sample cards of individual yarn types can be purchased for initial assessment. If required, a mixed sample card can be supplied instead.


If would like to discuss your specific absorbent requirements with a member of our team, please send us an email and someone will get in touch with you as soon as possible
