Handsheet

The improved sheet formation of foam-laid paper is shown visually in Fig. 2 where softwood kraft handsheets, water-laid and foam-laid are shown for comparison.

The handsheets from unbeaten pulps had greater stretch if press dried than thos from beaten pulps.

With this fiber, we then formed a series of air-laid and water-laid handsheets varying the temperature of the forming or rewetting water, the forming substrate, and, because press-dry effectiveness has been shown to vary with sheet weight, the grammage.
