An Investigation on the Production Possibility of NSSC Pulp and Fluting Papers From Kiwi Residues1

In this research, some chips pile of kiwi residues in the west of Mazandaran (Tonkabon region) were randomly chosen and NSSC pulps were prepared at the yield of 75% in 105 minutes, using the cooking conditions of MWPI of Mazandaran. Fluting papers were prepared from the Kiwi and Mill NSSC pulps of Mazandaran (control sample), first in a separate and then in mixed way. In order to improve the durability of handsheets, 5-10% of imported long -fiber were added to them. Then the optical and mechanical properties of handsheets were measured and compared according to the standardized tests. The results showed that the greatest strength to the burst, breaking length, tensile, RCT, porosity and opacity was in the handsheets obtained from the kiwi NSSC pulp% of imported long-fiber and the lowest strength was in the handsheets produced from the kiwi NSSC pulp. The results also indicated that the highest resistance to tear and brightness was in NSSC MWPI Mill, and the highest CMT and water absorption were in papers obtained from Kiwi NSSC. The results also pointed out that the above-mentioned strengths can be improved by adding 10% of imported long-fiber to the kiwi NSSC pulp. So the Kiwi NSSC Pulp % of imported long-fiber can replace some of the NSSC pulp of MWPI Mill, but it is not possible for the pure Kiwi NSSC pulp.
