Papermaking PAPERMACHINE – DRYING Introduction
(hydrogen) bonding. These forces also cause fibre straightening and microcompressions at bonding sites, as shown in Figure 1b. This starts at a consistency of about 20%, as shown by the comparison to glass fibres in Figure 2. This hydrogen bonding provides all the strength needed for most papers, i.e. adhesives are not added.

www.fibrelab.ubc.caThis is accomplished in screens and cleaners (hydrocyclones). The separated fibres then pass on to a thickener and then to the paper machine. The “rejects” are further refined in a “reject refiner”, and then screened again. We will talk a lot more about screening in upcoming lectures. Modern chip refiners are a marvel of mechanical ...
Papermaking PAPERMACHINE – PRESSING 1. INTRODUCTION
www.fibrelab.ubc.caThe total nip pressure curve is divided into a fluid pressure component and a fibre structure pressure component. The sum of these two components is equal to the total pressure. As the felt has much lower flow resistance than paper the fluid component is much lower in the felt than in paper. The fluid pressure component in the felt is dependant on
