“…Recently, foam forming was studied extensively to develop the understanding of foam-fiber interactions (Al-Qararah et al 2012Lappalainen and Lehmonen 2012;Lappalainen et al 2014;Mira et al 2014) and also to find the potential applications of this technology in papermaking Lehmonen et al 2013;Poranen et al 2013) as well as other specialty products, e.g., filters and insulators (Cervin et al 2013;Jahangiri et al 2014). Foam was introduced to the paper industry already in the mid-1960s.…”

Surface Activity and Foaming Capacity of Aggregates Formed between an Anionic Surfactant and Non-Cellulosics Leached from Wood Fibers

et al. 2019

This study relates to the release of non-cellulosic components (cell wall heteropolysaccharides, lignin, and extractives) from swollen wood fibers in the presence of an anionic surfactant (sodium dodecyl sulfate, SDS) at submicellar concentrations. Highly surface-active aggregates form between SDS and the leached, non-cellulosic components, which otherwise do not occur in the presence of cationic or nonionic surfactants. The in situ and efficient generation of liquid foams in the presence of the leached species is demonstrated. The foaming capacity and foam stability, as well as the foam’s structure, are determined as a function of the composition of the aqueous suspension. The results indicate that naturally occurring components bound to wood fibers are extractable solely with aqueous solutions of the anionic surfactant. Moreover, they can form surface-active aggregates that have a high foaming capacity. The results further our understanding of residual cell wall components and their role in the generation of foams.

“…Moreover, no wet pressing was applied in either process so as to leave a maximal trace of the foam-fiber interactions in the resulting network structure. Here the word "interaction" means any mutual influence between the two phases (foam and fibers) [12][13][14][15][16]. This influence may also be of geometric origin so that the bubble structure limits the orientation and movement of the fibers and vice verse.…”
