<Intelligent Evenness and Hairiness Tester with Expert System of Shanghai
GuoFang Co.> , abbreviated as <Evenness and Hairiness Tester>, adopts the
advanced data processing technique. It has a high accuracy, stability,
consistency and strong anti-interference ability for testing. the 'Expert Analysis
System ' can be customized according to different machine types for each
factory, and staffing can be reduced. So it is the best testing system along with
evenness equipment for hairiness in the cotton and wool textile factories.
< Evenness and Hairiness Tester> uses reliable industrial control computers with
operating system of windows 2000 or XP or Win 7. It has strong adaptability.
Auto-zeroing and automatic mean-adjustment is realized. It makes full use of
graphical processing technology for being operated easily. The selective printing
can be finished according to the needs after experiments. Advanced software
systems can provide data storage and maintenance information, and play a
leading role for controlling and improving the yarn quality for users.
Main technical data:
1.(1)Five Plates: 4 slots (1 slots for roving, 1 slot for sliver and 2 slot for yarn)
(2)Testing range for yarn: 4.0tex-20Ktex
Testing range for hairiness: 4.0tex-160tex
(3)Test speed for yarn(m/min): 4/8/25/50/100/200/400
Test speed for hairiness (m/min): 50/100/200/400
Test time for yarn (min): 0.5/1/2/2.5/5/7.5/10/20/30
Test time
for hairiness (min): 0.5/1/2/2.5/5/7.5/10/20/30
2.Test range of CV%: 0.20%-99.99%
3.Cutting length for CV-Length Curve: 1cm-990m
4.Test range of DR%: 0.01%-99.99%
5.CR%: the difference between of the average value and the sample value
Spectrum for yarn and hariness
6.(1)Wave length that can be measured of the standard spectrum: 0.1cm -
6000m,Channels for the standard spectrum: 85
(2)Wave length that can be measured of the standard spectrum: 0.1cm-2980m
Channels for the elaborated spectrum: 170
(3)1-60 spectrograms and CV of evenness can be displayed on the interface.
The commonly used threshold of the second sensitivity is: -40%, +35%,
+140%; -50%, 50%, +200%. Also test CV% value and the commonly used H
value of defect data and indexes for hairiness while hiding spectrograms.
Standard deviation SH value of indexes for hairiness can also be displayed.
Range selection: ±6.25%, ±12.5%, ±25%, ±50%, ±100%.
7.The distribution figure of the density-frequency of yarn
8.The distribution figure of the density-frequency of hairiness
9.One can analyze the reason of the flaws, and can switch from the spectrum of
yarn to the one of hairiness freely (vice versa).
10.Flaw sensitivity selection:
Thin sensitivity: -30%, -40%, -50% and -60% can be selected if needed.
Thick sensitivity: +35%, +50%, 70% and +100% can be selected if needed.
Nep sensitivity: +140%, +200%, +280% and +400% can be selected if needed.
11.Statistics function
(1)Statistical test data: the average value as Mean, the maximum value as Max
and the minimum value as Min.
(2)Test times for each operation is optional and the statistics can be done
according to years, months and days.
(3)Control Figures for yarn or for quality can be done by different article, by
different tex number or by different material (roving, silver or yarn). One can
statistic and analyze with the bulletin.
12.Control Figures for hairiness or for quality can be done by different article, by
different tex number or by different material (roving, silver or yarn). One can
statistic and analyze with the bulletin.
13.Expert analysis software
(1)One can switch to expert analysis software and can connect to the database
to store the information.
(2)Expert analysis software can be customized specially for the plant. The
software is designed by a professional book and the experienced author can train
and resolve the problems of the plant.
14.Others
Work environment: Temperature is 20±3 ºC , and humidity is 65±3%RH.
15.The supply voltage is AC220V±10%, and the frequency is 50Hz±5%
