Abstract:
|
The increasing use of secondary fiber in papermaking has led to the production of paper
containing a wide range of contaminants. Wastepaper mills need to develop quality control
methods for evaluating the incoming wastepaper stock as well as testing the specifications of
the final product. The goal of this work is to present a fast and successful methodology for
identifying different paper types. In this way, undesirable paper types can be refused, thus
improving the runnability of the paper machine and the quality of the paper manufactured. In
this work we examine various types of paper using information obtained by an appropriate
chemometric treatment of infrared spectral data. For this purpose, we studied a large number
of paper sheets of three different types (namely coated, offset and cast-coated) supplied by
several paper manufacturers. We recorded Fourier transform infrared (FTIR) spectra with the
aid of an attenuated total reflectance (ATR) module and near-infrared (NIR) reflectance spectra
by means of fiber optics. Both techniques proved expeditious and required no sample
pretreatment. The primary objective of this work was to develop a methodology for the
accurate identification of samples of different paper types. For this purpose, we used the
chemometric discrimination technique extended canonical variate analysis (ECVA) in
combination with the k nearest neighbor (kNN) method to classify samples in the prediction
set. Use of the NIR and FTIR techniques under these conditions allowed paper types to be
identified with 100% success in prediction samples. |
