ABSTRACT:
A hydroentangled nonwoven fabric containing ribbon shaped staple synthetic fibers having a crenulated cross-section and formed from a wet-laid web containing such crenulated fibers, preferably a blend thereof with short natural fibers, such as wood fibers. The use of a wet-laid web containing such crenulated synthetic fibers enables optimal interaction with the hydroentanglement jets of water, and a reduced level of hydroentanglement energy is required to achieve the desired performance characteristics in the fabric.
