Effects of certain key metrics of hydroentanglement system on properties of nonwoven fabrics made with commercially cleaned greige cotton. Innovative Nonwovens Conference.

Interpretive Summary: Technical Abstract: Research was conducted to determine the effects of certain key process metrics of a commercial-grade hydroentanglement system on properties of the nonwoven fabrics made with cleaned Upland greige cotton lint. The metrics studied, among others, were the hydroentangling water pressure, the strip orifice size, and the number of hydroentangling impacts. The main fabric properties evaluated were air permeability, whiteness, tensile breaking strength and elongation, burst and tear strengths, and water absorbency. The results have shown that all the process metrics studied generally have considerable influence on the fabric properties, although their degrees of impact varied considerably depending on their interactions. Specifically, the higher hydroentangling water pressures, finer strip orifices, and greater number of hydroentangling impacts generally produced stronger, whiter, and more absorbent fabrics of lower air permeability, while requiring more energy for the hydroentanglement. The research has also shown that the various process metrics can be widely varied to optimally attain the desired fabric properties more efficiently at lower energy requirements. |
