Individual cellulose ﬁbers were studied to identify the transport and absorbtion phenomena as well as the inﬂuence of drying. A Chalmers University of Technology developed method within ESEM (Enviromental Scanning Electron Microscope) has been used in this study. The results from the laborations gave the following conclu- sions: The transport of water occurs in ﬁbers in the ﬁber wall surface and the lumen. Collapsed ﬁbers can only transport water on the outside and has generally slower absorption rate than non-collapsed ﬁbers. In some cases a better transportation capacity can be observed, because the surface structure of the ﬁber is important in regards of transportation. Horniﬁcation results in a size reduction of pores on the surface of the ﬁbers. Drying processes increases horniﬁcation of ﬁbers, this has been shown to give lower absorptive capacity.
