Abstract
Synthetic fiber papers were prepared and bonded by aqueous polymer dispersions added either entirely at the wet end or by a combination of wet end addition and saturation. For wet end addition, the best binder was Chemigum 245B, a butadiene-acrylonitrile rubber latex, while Polycryl 7-F-1, an acrylic latex, was the best binder for addition by saturation. Best results were obtained with a mixture of viscose rayon and nylon fibers, the latter being of the water dispersible type. Curing at 150C either in an oven or between platens improved physical properties, particularly wet tensile strength. Aging resistance was evaluated. Some of the laboratory handsheets prepared were comparable in physical properties to commercial air-formed non-woven fabrics. An 18 inch paper machine with an inclined wire was used to demonstrate that machine formation was possible.
