Abstract: Hydroentangling is traditionally a nonwoven process of manufacturing fabrics through entangling loose webs of fiber using jets of water. This research proposes hydroentangling woven jacquard base fabrics using several speed and pressure combinations to mechanically enhance the structure. It also proposes to hydroentangle a loose web of fibers onto a woven jacquard fabric as a form of mechanically bonding the two structures. By bonding these fibers onto the woven fabric, the structure will be stabilized and mechanical properties will be enhanced. Control fabrics were compared to hydroentangled samples in order to select optimal hydroentangling processing parameters. The effects of these process parameters on fabric properties were studied. The mechanical properties of the woven fabrics before and after hydroentangling were also assessed. One objective of this research is to determine if hydroentangling is a feasible means to overcome certain physical and mechanical shortcomings of jacquard woven fabrics. Test data indicates that certain aspects will be improved, while others may be negatively impacted by hydroentanlging. There are also critical energy points where any further enhancement in properties is diminished. The end use application of the fabric, as well as performance criteria will play a key role in determining if hydroentangling can be used as an alternate means of finishing a jacquard woven fabric, and will be unique to the specific company and production capabilities. A second objective of this research is to determine if hydroentangling is a feasible means of bonding a single fiber carded web onto a base jacquard woven fabric. With the correct combination of base fabric construction and specific energy, bonding is possible. When energy is too high, the design will be jeopardized, while if energy is too low, adequate entanglement will not happen. Test data indicates that certain properties will be improved, while others may be negatively impacted by hydroentanlging. The end use application of the fabric, as well as performance criteria will play a key role in determining if hydroentangling can be used as a feasible means of bonding a jacquard woven fabric with a carded web, and will be unique to the specific company and production capabilities.
