제지공정의 유기 충전제로서 침엽수 잎 분말 적용

Abstract

The application of conifer leave to the papermaking process as a functional organic filler was investigatedin this study. The powder of the conifer leave after hot water extraction for the functional extract, suchas phytoncide, was applied to OCC stock. The comparison between the commercial wood flour and theconifer leave powder as organic filler for OCC paper were conducted with various wet pressingconditions. The amount of the water removal by the wet pressing process and the bulk of handsheet wereincreased by the addition of the wood flour and the conifer leave powder, although the tensile strengthwas decreased. At the higher pressure condition of the wet pressing, the wet pressing efficiency wasgreatly increased by the wood flour and the conifer leave powder. There was a little difference in the performanceof the wood flour and the conifer leave powder as an organic filler. Those results showed theconifer leave powder could be an alternative resource to the wood powder for papermaking organic filler.
