We have analyzed the effect of drying method on creep in specially dried handsheets made of three different pulps. The drying methods simulated cylinder drying and impingement drying. Standard handsheets were also made. We found that the combination of drying method and pulp together determined the creep behaviour. None of the drying methods considered gave the smallest creep strain for all pulps and all testing times. It was also impossible to put the pulps in a general ranking order regarding creep, irrespective of drying method. However, for all the drying methods that we tested, the lignin-containing high-yield pulp always gave the smallest creep strain, while the effect of hemicellulose coupled with the drying method was indistinguishable.
