THE EFFECT OF PRODUCING NATURAL DYEING FROM RED PINE BARK AND THE USING EFFECT OF ORGANIC MORDANT IN PAINTING

Abstract

The barks of coniferous trees are peeled in the forest in the production of logs. Peeling barks are left to rot in the forest.The aim of this study is to convert red pine bark, which remains idle in the forests after logging, to benefit.One of the aims of this study is; gaining economies of lignocellulosic waste. This is especially important for the cleaning paper industry, the health products sector and for the paper products sector used by students (especially for kindergarten and primary school students).On the other hand natural dyed paper is produced and both human health and environmental pollution is prevented. Red pine bark was used for natural dye production. Grape juice vinegar was used as mordant. Wood pulp was brought from abroad through a private sector. Eaucalptus grandis tree was used to make wood dough. Spectrophotometer measurements focused specifically on color difference and Kubelka Munk(K/S) values. It was also made in mordant painting. Extraction method was preferred in natural dye obtained. Pure water was used in the extraction process. After the dyeing process, color measurements of the dyed papers were done by spectrophotometer. At the end of the study; It was determined that the natural dyes obtained were fixed to wood cellulose. It has been observed that grape vinegarin creases the coloring properties.
