What is SAF™?

SAF™ Super Absorbent Fibres: Think of SAF™ as similar to Super Absorbent Powder (SAP) but in fibre form, it is this that makes SAF™ special. SAF™ is highly absorbent, locking away liquid within seconds. It can  also be converted into a wide range of fabrics and yarns.

SAF™ is commercially sold in 250kg bales.

SAF™ Super Absorbent Fibres: SAF™ can be converted into a wide range of superabsorbent fabrics and spun yarns. When blended with other fibres – and fabric layers – the amount of different product variants that can be achieved is endless. Within these converted products, distribution of the SAF™ is homogeneous and uniform. The fibres are entangled and fixed in the structure with minimal migration, resulting in consistent absorption performance and no dusting.

The fibres have a large aspect ratio allowing them to absorb aqueous fluids very quickly. Standard SAF™ is 10 dtex and the fibres are precision cut with staple lengths of 6, 52 and 80mm available.

SAF™ is naturally white. The creation of dust and respirable particles is minimal during its manufacture and conversion compared to other superabsorbent technologies – improving safety down the supply chain to the end users. The fibres do not melt and are stable up to 200°C.

The production process we use to manufacture SAF™ is water-based to improve safety and environmental performance. The fibres also have a good biocompatibility profile and have been assessed by FDA and EFSA for use as an absorbent in food packaging.

Due to excellent integration during conversion into fabrics and yarns, no adhesives or thermal-bonding treatments are required to keep the fibres in place. Small samples can be purchased to trials here
