Yarns and films from ligno-cellulosic fines
Abstract
In this work the feasibility of the novel low-costlignocellulosic fines (LCF) as a raw material ofbiodegradable all-cellulose applications, namely yarnsand films, was investigated. LCF was prepared fromsoftwood (spruce) using a traditional wood grinderequipped with a special patented V-surface stone.Produced LCF particles were in micrometer scale. Thechemical and elemental composition analyses for LCFexhibited the chemical structure of native wood.The short length and rather low aspect ratio (whencompared e.g. to cellulose nanofibrils) limited thebonding capacity of LCF particles, and a compositeapproach was chosen for the preparation of yarns andfilms. Carboxymethyl cellulose (CMC) was used in bothcases as a binder polymer, and glycerol was used as aplasticizer. The yarns were made with dry-jet wetspinning with aluminium sulfate crosslinking. This methodallowed fast manufacturing of the yarns with reasonablemechanical properties. The films were made with a simplesolvent casting technique.The chemical composition, crosslinking mechanism, andmechanical properties of the composite yarns and filmswere investigated. The tensile strength of the LCF-CMCyarns was higher than whole hardwood fiber-thermoplasticstarch composite yarns but below that of cellulose yarnsmade from pure viscose. Addition of plasticizer was foundto give positive impacts on the flexibility and handlingof the yarns. The tensile strength of LCF films wasrather good being comparable e.g. with CMC-starchcomposite films and pure cellulose acetate films.The investigated low-cost fines are obviously aninteresting novel option for all-lignocompositeapplications with cellulose derivatives, wherebiodegradability and biobased characteristics are desiredproperties.
