Super Absorbent Fiber (SAF™) technology is at the core of every product, and provides rapid levels of absorption – it is capable of absorbing up to 200 times its own weight in water – and excellent retention. SAF™ is similar to Super Absorbent Powder (SAP) but in staple fibre form, and is inherently super absorbent. It is this – plus the fact it can be blended easily with other synthetic and natural fibers.
