The Comparison, Measuring & Labelling of Energy-efficient Textile Machinery
Drive technology
Example : in the case of drives, there
are differences in efficiency and
different efficiency classes caused by
the functional principle and which are
partially determined by legislation. The
machinery manufacturer also
influences this parameter group, but
the selection of the principle used in
the drive is limited by the application.
Waste material/rejection rate
Material efficiency also means energy
efficiency. Machines that avoid rejects
or that produce a significantly lower
percentage of waste thus save energy.
Any error that must be corrected
immediately after it occurs or in a
subsequent process step costs
additional energy.
Ultimately, it is important to realize the
true extent of the influence of the
machine manufacturer on the energy
efficiency and what contribution the
textile manufacturer can and should
make. To obtain an estimate, the
influence on the different parameters
is broken down in the following way :

example of a factor which determines
energy efficiency, since all staple fibres
from which a yarn is produced must
pass through this textile machine. This
is even independent of the subsequent
process used to create the yarn. But
even with this standard process there
are many parameters that affect energy
efficiency.
Yarn manufacturing – OE spinning
machine
The open-end spinning machine is one
of the three established spinning
processes for manufacturing yarn.
Variations within the Oe spinning
process are very minor, so that one
can speak of a standard process. But
even with this process, there are again
many variables outside the common
parameters that affect energy
efficiency.
