The Comparison, Measuring & Labelling of Energy-efficient Textile Machinery
By the choice of fibre raw material quality as well as the
selection of spinning and production parameters (operating
point), the textile manufacturer defines key parts of the
specific energy use in yarn production which do not
necessarily result from the requirements of the finished
product.
Fabric manufacturing – warp knitting machine
Warp knitting is a very flexible and high quality process for
manufacturing fabrics. The enormous diversity of warp
knitting makes this process step a very good example
of the complexity of energy efficiency assessment. The
type of warp knitting machine employed has a major
influence on energy efficiency.
Finishing of fabrics – dyeing line
The closer the process of manufacturing which is being
studied comes to the final product, the more complex are
the factors influencing energy consumption. The dyeing
process is an area in which additional crosssectional
technologies with significantly higher specific energy inputs
are used. In addition to electricity, direct primary energies
and water are used to a high degree as energy sources.
