2. 1. High strength paper from high yield pulps by means of hot-pressing

   Author : Tove Joelsson; Per Engstrand; Gunilla Pettersson; Anna Svedberg; Samuel Schabel; Mittuniversitetet; []
   Keywords : high yield pulp; hot-pressing; lignin; paper properties; wet strength;

   Abstract : AbstractHigh Yield Pulp (HYP), i.e. TMP, SGW or CTMP, is normally used in printing papers (News, SC and LWC) or in a middle layer on cardboard i.e. READ MORE

4. 2. The influence of stress variations in wet pressing

   Author : Jörgen Gullbrand; KTH; []
   Keywords : press felts; roughness; smoothness; surface structure; uniformity;

   Abstract : Two methods for the measurement of micro-scale stressvariations of press felt surfaces were developed. The methodswere based on a thin plastic film that was coated with anopaque stress-sensitive layer (Cronapress conversion film). Thefilm was compressed between a felt and a smooth surface. READ MORE

5. 3. On the Modelling of Mechanical Dewatering in Papermaking

   Author : Vinicius Lobosco; KTH; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; paper; modelling; dewatering; forming; wet pressing; fibre network stress; rheology; hysteresis; intra-fibre water; compressibility; structural stress; stress-strain; restricted gels; swelling;

   Abstract : Most of the water fed into a paper machine is removedmechanically in the forming and press sections. One of thefactor which has an important influence on mechanicaldewatering, i.e. in both forming and pressing, is thestress-strain behaviour of the fibre network. READ MORE
