Abstract
Disclosed is an improved high sorbency nonwoven fabric and its use particularly as an oilsorb material. The high sorbency nonwoven is preferably made by meltblowing and perturbing thermoplastic fibers of, for example, propylene polymers. The sorbent nonwovens have high bulk and strength, oil capacity and oil absorption rates making them particularly suited to such applications. Treatments and additives for such materials are also disclosed.
