Effect of chitosan addition on the surface properties of kenaf (Hibiscus cannabinus) paper

Mechanical and Antibacterial Properties of Paper Coated with Chitosan

“…The intention of coating is to provide better properties for paper, especially in terms of tensile strength, folding endurance and tear resistance. In addition, the aesthetic values in paper, such as brightness and smoothness could be improved (Ashori et al 2005).…”

“…Polymer type polyelectrolytes had been widely used in papermaking especially as an external size, additives or fillers that can modify the pulp fibre surfaces and solids suspension to be more homogeneous and had a strong attraction between all the components available, especially between the pulp fibres (Ashori et al 2005). A number of these synthetic additives are non-biodegradable and may cause environmental problems and some pose occupational health and safety risks to paper industry workers.…”

Active ingredient-containing chitosan/polycaprolactone nonwoven mats: Characterizations and their functional assays

“…Although the mechanical problem was solved by using these blends, one drawback remains: the most active ingredient (i.e., CS) was embedded and not exposed to the surface of the film to perform its intended function. In respond to Ashori et al work [3], they found that the coating of CS to a sheet formed from beaten fibers exhibited improvement in surface properties. Therefore, we proposed a design with a CS overlayer on top of the PCL fiber, rather than the CS-PCL blended fiber, and expected to demonstrate improvements on various aspects of our produced materials.…”

“…Based on these requirements, chitosan (CS), a natural polymer gaining considerable attention in applications such as anti-bacterial additives [2], paper sizing agent [3,4], and food preservatives [5,6], is an ideal material for wound dressing. However, directly processing CS to manufacture wound dressing is difficult because the mechanical properties of CS alone are poor and unable to withstand the rigors of daily human activity.…”

Preparation and Oil-Resistant Mechanism of Chitosan/Cationic Starch Oil-Proof Paper

“…Ham-Pichavant et al (2005) investigated the reactions between CTS and fatty acids by calculating the amount of free fatty acids. In addition, cationic starch, a natural polysaccharide, is widely used in the coating process to improve the barrier and mechanical properties due to its excellent film-forming and biocompatibility (Ashori and Raverty 2007;Saraiva et al 2010;Guazzotti et al 2014), and the mixture of chitosan and cationic starch have been reported as sizing agent and dry strength agent of paper (Ashori et al 2005(Ashori et al , 2013. These studies indicate that CTS and CS can be used as a composite oil-resistant agent for food packing.…”
