Common polyester fibers are hydrophobic in nature. Thus it is hard to process the fibers in the hydroentangled nonwoven process and the resultant nonwoven fabric is hydrophobic as well. In this paper, two kinds of polyester fibers treated with different hydrophilic finishing agents and one common polyester fiber were formed into nonwoven fabrics by using hydroentanglement process. The influences of the hydrophilic and friction properties of the PET fibers on the properties of hydroentangled nonwoven fabrics were studied.
