Study on production of fluting paper from wheat straw soda – AQ pulp and OCC pulp blends

Abstract

This study was carried out with the aim of producing fluting paper from wheat straw soda–AQ pulp and OCC pulp blend. Handsheets at 120 gr/m2 basis weight were made by blending the unbleached wheat straw pulp with OCC pulp at ratios of 25, 50 and 75%. Physical and strength properties of these papers were measured and compared to unblended papers. Results indicated that, paper properties were considerably affected by incorporation of the wheat straw pulp. In other words, in case of utilizing wheat straw soda – AQ pulp in OCC pulp , acceptable physical and strength properties can be produced , so that , the incorporated 75% of wheat straw pulp to OCC pulp, the best thickness, air resistance, roughness, tear index, burst index, folding endurance, breaking length, CMT and RCT can be achieved. According to obtained results, unbleached wheat straw soda – AQ pulp can be used not only to enhance the physical and strength properties of fluting paper but also as a lignocellusic source for making fluting paper.
