Classifiber Fibrograph

Classifiber fibrograph  is used to determine cotton fiber mean length, upper half mean length and uniformity index by photo-electric method.This instrument is designed according to random distribution theory of cotton fiber length, and the theory of that light intensity through fiber bundle has a negative relation with fiber number within fiber bundle cross section.

• Use PC on-line technology, and get cotton fiber length shadow curve, fiber mean length, upper half mean length and uniformity index, etc.
• CPU generates trigger plus to control step motor speed, and drive sampling comb with required step-size, easy to control data frequency;
• High quality LED light source, sensitive silicon photocell to receive light signal, simple operation;
• PC auto process data, generate fiber length curve after post-fitting, and then get cotton fiber mean length, upper half mean length, uniformity index and short fiber content;
• Calibration instrument by computer, and create database ( storage, inquire, print, etc);
• Special designed sampling device, easy to sample.
•  Fast test speed, test one test result only need 20~30s

Parameter:

•  Cotton fiber length range: 18mm-50mm;
• The average length error of the upper half of the cotton fiber: 0.5mm; (At present, this index is used both internationally and domestically)
• Uniformity index error: 2%
• cotton fiber sampling AMOUNT (equivalent to the number of fiber roots) : 500-900;
• Short fiber rate: percentage of root number
