“…Accordingly, Figueiredo et al [161] found that the wet expansion under tension is strongly affected by the filler content. The excessive addition of inorganic fillers reduced the paper web dimensional stability in the cross direction (expansion of *2.4 to *2.75% for ash contents of *23 to *36%).…”

“…As already explained, the expansion of single fibers is higher in the transverse direction than in the longitudinal direction. The expansion of paper in cross direction (CD) is up to 7 times higher than in the machine direction (MD) [25,161,185,186]. However, fibers are not 100% parallel in reality and the orientation is determined by several variables of the papermaking process.…”

Paper is a widely used packaging material and is nowadays regaining importance, e.g., as bio-based and biodegradable material. Moreover, new technologies such as polymer-fiber composites, printed electronics and the deep drawing of paper are developing. The process stability and also the resulting quality of paper converting processes such as coating, metallization, printing, and the printing of electronics are highly affected by the hygroexpansion of paper. In order to reduce production instability and to choose and develop paper substrates with ideal characteristics, critical parameters need to be known. This paper offers an extensive overview of those parameters, starting at a molecular and microscopic level with the effect of the constituents and morphology of single fibers, before moving on to paper contents, chemical modifications and additives and finally concluding with paper production and fiber network modification. It was found that the major influences are single fiber sorption, inter-fiber contacts, microfibril angle, fiber morphology (length, width, curliness) and fiber orientation. This review gives new ideas and insights for technologists working in research, development and production optimization of paper-based products.

“…While PCA selects a direction that retains the maximum structure of data on a reduced dimension, SDA selects a direction that achieves maximum separation between given sample classes (Berrueta et al 2007, Li et al 2014Figueiredo et al 2016). Stepwise regression was introduced to screen key VOCs components as characteristic chemicals to make a classification.…”

Agarwood can be divided into resinous heartwood from the Hoi-An zone and Sin-Chew zone. Traditionally, an experienced human grader classifies agarwood by odor. However, sensory errors can follow from subjectivity, poor reproducibility, and time consumption during manual work. In this study, agarwood samples were heat-treated to release volatile organic compounds (VOCs), which were analyzed using the thermal desorption -gas chromatograph mass spectrograph (TD-GCMS) method and chemometrics analysis. The classification of agarwood was then identified. Sesquiterpenes and other aromatic compounds were the main compounds of heat-treated VOCs. Twenty-six characteristic compounds were screened via stepwise regression. Fisher discriminant analysis and Bayes discriminant analysis were conducted, based on the 26 compounds, to classify the agarwood samples. Discriminant functions of the two analysis methods were obtained.The results showed that it is feasible to use the TD-GCMS method combined with chemometrics analysis to analyze VOCs from heat-treated agarwood instead of experienced graders to classify the agarwood samples as being from either the Hoi-An zone and Sin-Chew zone. This study also provides a way to classify unknown samples by odor through 26 characteristic compound'srelative peak area and the discriminant equations, offering the possibility of testing an unknown sample's cultivation region.
