Technical Abstract: A study was conducted to determine the effects of two popular web-forming technologies, viz., the Rando air-laid technology and the traditional carding technology, on properties of the hydroentangled nonwoven fabrics made therewith. The fibers used in the study were greige cotton, bleached cotton, cotton derivatives (e.g., gin motes and comber noils), and cut-staple polyester. The hydroentangled fabrics produced with the two systems were mainly evaluated for their physical and mechanical properties, absorbency, absorbency capacity, and whiteness. The study has shown that, with the exception of greige cotton linters, the greige cotton lint, greige cotton gin motes, and even greige cotton comber noils, either alone or in blend with the other fibers mentioned, can be mechanically processed into hydroentangled nonwoven fabric structures without any insurmountable difficulties. Further, the air-laid webs, when compared to the carded webs, consistently yield a considerably higher fabric tensile strength in the machine direction (MD), but there doesn’t seem to be much of a difference in the cross direction (CD). The fabric absorbency, the drop test and the capacity were very similar for both the carded and Rando webs. However, the addition of synthetic fibers increases sink times of the fabric in both the carded and Rando web-forming systems. The drop test and sink time followed each other pretty closely, as the drop test time increased so did the sink times. The “whiteness” of fabric, which is significantly more dependent on the fabric’s constituent fiber content than on the fabric’s surface-based light reflection, obviously varied considerably. However, the whiteness index within the same fiber types and their blends shows no trend of significant difference between the fabric produced with carded fiber web and the fabric produced with random Rando fiber web.
