Physical and Mechanical Properties of Reborn Paperusing Waste Still age from Sweet Potato‐shochu Distillery

低圧力(0.55～2.87KPa)の条件のもと作製した蘇生紙の物理および力学的性質を把握するために密度、引張り、引裂き、破裂試験を行なった。その結果、力学的に最も良好な結果を示したのは新聞古紙の混合比2%で作製した蘇生紙であった。また焼酎蒸留粕に添加する新聞古紙量が同じ場合、廃液の有無に関わらず紙の力学的性質にほとんど変化がなく、これらの条件下で作製した蘇生紙は、新聞紙、PPC用紙や蒲生和紙よりも強度的には弱いことがわかった。This research was also to clarify physical and mechanical properties of the reborn paper made from waste stillage from shochu distillery and old newspaper under the conditions of low pressure. As a result, the most satisfactory values of density, tensile-, internal tearing-, and burst strength were obtained by adding old newspaper with the content ratio of 2%. Under the condition of adding same amount of old newspaper to waste stillage from shochu distillery, regardless of waste water content, low pressure did not have influence on mechanical properties of reborn paper. It is clear that the strength of reborn paper was frailer than newspaper, PPC paper and Kamo-washi
