COMPARISON OF MOISTURE RELATED PROPERTIES OF PET/CV BLENDED NONWOVEN FABRICS

Abstract

Moisture related properties of polyester (PET) / viscose (CV) nonwoven fabrics were investigated in this research. Four different nonwoven fabrics, PCV0, PCV1, PCV2 and PCV3, having different viscose proportion namely 0%, 30%, 50% and 70% were selected, respectively. The manufacturing techniques and fabric thickness values were kept the same for the comparison of tested fabrics. Moisture absorption, vertical water wicking, air and water vapor permeability tests were carried out and also moisture transmission performance of the blended nonwoven fabrics was examined in order to evaluate the effects of fiber ratios on moisture related properties of the blended fabrics. It was determined that higher viscose content in the blended fabrics result in higher vertical water vicking performance of the fabric. The moisture content of the fabrics also increased with increasing viscose proportion. This is most probably because of the high moisture absorption capacity of the viscose fibers. The wetting time and wetting radius results are in reverse ratio with the viscose proportion of the fabrics in moisture management test. It can be also stated that permeability properties depend not only viscose content but also fabric structural parameters.
