A Replacement For The Skein Reel A Proven, Reliable Turn-key System
A Remarkable Cost SaverThe STC-4000 is the latest advancementin Cost Efficient-Highvolume test stations
So highly refinedand automated thatup to 10 yarn test and comparisons to standard are madesimultaneously.So complete in it’sdesign and softwarethat labor cost and opportunity for humanerror are almost com-pletely eliminated.So carefully appli-cation engineeredthat it’s designed for use in the productionarea.So State-of-the-Artthat it will obsoleteand out perform allother methods of yarn denier (Dtex)measurement anduniformity measurement
SimultaneousDenier/Interlace
Evenness TestingThe STC-4000 is a
revolutionary developmentbased on the FMS-8000
On-Line Monitoring System.
Proven MeasurementConcepts
STC used it’s patented andproven design of ultra
sensitive optical sensors to measure mass (denier) and
Interlace (nodes/ meter).The sensor measures yarnat a sampling rate of 16,384
samples per-second .
Additional Features are attained
by incorporating a secondcontrolled drive motor in theyarn transport system theDraw –Force measurementfeature was incorporated.
The addition of being able tochange the draw-ratio between
the two independently con-trolled transports also allowsthe ability to measure bulk
levels of some yarns.
A Process Management Tool More than a laboratory Instrument
• High
MeasurementsEach channel of the multi-
position STC-4000 produces a real-time graphic display of the variability which is presented onthe computer monitor with thenumerical data. If specified aneasily readable Digital Spect-rogram can be produced to
clearly show periodic defectsand their wave length.
Cost Saving are Numerous

Highly AccurateMeasurements +/- 1%
Correlate with All Traditional Test Methods
Long Term Average Denieris computed as the mean of all
short term denier measurements inthe entire yarn sample.
Tolerance Limits tests are Performed at two levels.
Close limits for minor varia-tions and wider limits for
rejecting packages.
Hi Denier& Lo Denier Values within each sample areprinted out on the summary.
Denier Evenness %CV is measured by computing the Coefficient of Variation of allshort term denier values over
the entire yarn sample.
Long Term or Short TermDefects can be emphasized at
will by selecting high or lowsmoothing factors
Interlace nodes are measured and averaged overthe entire yarn sample nodes
per meter and the node intensity is reported
Automatic Quality Control Station The STC-4000 Fiber Quality Control Station is a high throughput and self-contained,
computer controlled production testing system which automatically performs a series of standard, objective, quality control tests on a very
large number of yarn samples per day. It is designed for around-the-clock use as part of the fiber production process…or as an incoming inspection
tool for fiber users.
When used in a fiber producing plant an STC-4000 can be used to:
Improve control of spinning Assure quality of final
production.Provide objective proof ofyarn quality to refute customer claims
When installed in a texturingor yarn processing plant, an
STC-4000 can perform qualityTests on sample packages so
as to:
Grade incoming shipments. Accept feeder yarn shipments. Reject feeder yarn shipments.
Predict textured yarn characteristics
