Cellulose is an important raw material in the manufacture of paper. Cellulose is formed by the
felting, fringing, swelling by absorbing water of the fibers and the combination of these fibers
as a result of certain processes. Paper is also obtained by processing plant fibers. It is also
possible to reuse the waste paper, which are completed in utilization, in paper production by
recovering the cellulose in its structure. Recycling is the process of transforming these waste
papers, which can be reused, into a second raw material by subjecting them to physical or
chemical processes. In addition to being sustainable, significant savings are achieved in the
amount of raw materials used in paper recycling. In addition, this saving is economically
beneficial to production due to the high cost of raw materials.
In this study, natural dye plants and natural dyeing methods were used to produce paper from
recycled cellulose with the aim of increasing sustainability. In order to prevent the negativities
originating from the increase in carbon emissions that synthetic dyes cause, it is aimed to
increase the use of natural dyeing methods in paper production. Since natural dye plants are
produced from plant itself or its waste, they do not cause environmental pollution and provide
advantages for recycling.
In this study, cellulose fibers were colored with natural dyeing method using walnut shell.
Thus, between the fibers, samples colored with walnut shells and samples that were not
colored were examined under two different conditions. Samples were prepared in two
different ponds, 5 L and 8 L, with a fixed ratio of solids. Paper sheets were formed with the
sieve using the dipping method in the prepared concentration and at the same time, the
technical properties of the samples were examined by reducing the fibers at a certain rate.
Samples were measured in terms of weight, color measurement, light fastness, contact angle,
surface smoothness, air permeability and compared with the data obtained.
