Loepfe cares about fabric appearance
Uince 1955 from Switzerland, Loepfe
Brothers Ltd. with its optical yarn clearers has revolutionized
quality control in the textile industry. Loepfe is considered
world-wide as the specialist for integral quality control
systems. About 50% of the world-wide yarn production are
monitored by Loepfe yarn clearers.
The fabric appearance is the ultimate reference if all the
production processes before were under control, it decides in
the end if the yarn performance will meet the requirements of
the fabric in regard of production and of the anticipated look
But how is a good fabric appearance defined?
The general expectation for a good fabric appearance is based on
various factors, such as an even fabric surface, no disturbing
faults like thin and thick places, and homogeneous level of
hairiness according to the end-use of the fabric, the absence of
any kind of foreign matter as well as an uniform color and shade
of the fabric. All these parameters are captured instantly and
evaluated visually by the human eye.
Loepfe ZENIT+ offers various possibilities to focus on
yarn parameters that are important
for the desired fabric appearance.
One of the decisive factors for a perfect fabric appearance
is the quality of the yarn which is used for its production.
Loepfe yarn clearers trust on the optical measuring principle
for more than 60 years. The latest Loepfe ZENIT+
offers various possibilities to focus on yarn parameters that
are important for the desired fabric appearance.
With Loepfe’s well known LabPack
online laboratory function, the customer can detect all
parameters affecting the fabric appearance with 100%
reliability: off standard bobbins can be eliminated with
settings for hairiness, yarn irregularities, neppiness, diameter
variation VCV, and IPI alarm functions.
On top of these well-established functions of
ZENIT+, Loepfe offers now the brand new Off-Color
detection to secure your fabric appearance even more. This
latest innovation detects absolutely dependable colour and shade
variations which e.g. can be caused by the insufficient blending
of the raw material. Shade variations can lead to disturbing
stripes in the finished fabric. lf only one cone in a weaving or
knitting system shows a deviating colour or shade, the whole
fabric is ruined and cannot even be graded as second quality
anymore. This can end in costly claims for the spinning mill.
Another milestone by Loepfe is the proven Foreign Matter
detection system, for detecting even the finest Foreign Matter
remains from the finest to the coarsest yarn counts. Also,
Foreign Matter in dyed yarns can be detected unfailingly.
Ideal measuring principle
Optical yarn clearing is and remains the ideal measuring
principle because the quality of finished fabrics is always
assessed by the human eye. Loepfe ZENIT+ follows the textile
quality control by the parameters of the human eye.
