Sažetak
The research of high grades papers bindability by Perfect binding method is main interest of this scientific mission. This is one of the leading binding techniques in the industrial paperback production. Furthermore, application of thermoplastic adhesive (rapid setting time) is main contributor to rapid production and low-cost of paperback products. On the other hand, paper surface properties have strong influence on adhesive bond strength. Hence paperback bindability depends on paper surface properties. Paperback is adhesive bound product ; flat-back binding method includes loose leaves binding edges assemble to create a text block spine after roughening treatment. Text block spine is filled with adhesive thick layered film. The loose leaves are locked in fixed text block spine without radius as consequence of adhesive rigidity. Paperback openability reduction causes loose leaf adhesive joint strength changes, and those changes depend on loose leaf position in text block. Paper bindability can be explained on the basis of adhesive joint strength results. The term bind ability refers to the quality of adhesive bond expected when applied to the particular paper. Bind ability, which comprises both physicochemical and technological paper properties, is a particularly important feature of paper containing primary fibers. Paper technological properties term is focused on the adhesive-paper base interrelation, which is very important to obtain high quality bookbinding. The binding process always involves interaction between adhesive and the binding materials, i.e. the paper. Therefore paper types, particularly its surface properties are fundamental to the appearance of the finished adhesive bond characteristics. Adherend increasing (paper roughness) improves adhesive kinetic wettings and its plastic deformation into cavities volume. On the other hand, the adhesive has to meet many important requirements before its bond is considered. Adhesive has to mechanically lock to paper, it has to set quickly and it has to able to bind. The aim of this research study was to assess the suitability of various wood free paper and ground wood paper for bindability by means to the perfect binding technique. Adhesive bond strength assessment involves adhesive joint strength determination, where, pull test is used for adhesive joint failure mode characterization. Results directly explain high grades papers bindability. FOGRA recommendation rating directly confirms paperback binding quality with high grades papers application. The main benefit of this research study is defining influence of physicochemical properties of materials (paper, adhesive) on high grades papers bindability. In additional, this binding technique is more unique because its interest to adhesive joint formation.
