Zorb I (white, like batting) does not recover when stretched. It has a little strength to resist separation. It would require an additional layer such as cotton to provide structural strength. As such, it’s possible for this material to lose shape and start piling after numerous machine washings.

Depending on the construction technique, Zorb is able to absorb over 3 times its weight in fluid. A square or circular thread pattern with cotton can strengthen the structure and life of this fabric. Plus, adding a thread pattern will reduce piling that can be experienced after numerous washes.

By weight and volume, Zorb absorbs between 2 - 3 times its weight. By comparison of absorption rates with double-gauze cotton, it absorbs approximately 2 times faster and hold significantly more fluid.

When wet, Zorb is highly flame resistant. There is no significant shrinkage in this fabric when wet and heated. When dry, Zorb is somewhat resistant to fire and becomes brittle. Zorb has a black smoke and toxic smell when burned. Plus, it leaves a yellow residue on the surface. Cotton, on the other hand, will burn very quickly, leave no residues, and smells like burning wood.

When compressed with typical body weight and saturated, Zorb has a low retention rate. Simply put, approximately 60-85% of all fluid is pushed out when sat on. This means you will need a layer of fabric to act as a barrier above the Zorb.

Zorb 1, by itself, would not perform very well as the sole fabric of a diaper. Zorb seems best suited as a quick soaker that can quickly redistribute fluid to other parts of the diaper when compressed. This fabric is meant to be combined with other fabrics for the best diaper performance.
