Fibrograph, which is also named photo-electric length machine, digital fibrograph. FYI is one of the leading manufacturers and suppliers of fibrograph machine in the world, devoting to offering cost effective testing solutions and equipments for various industrial applications.
The Fibrograph manufactured by FYI based on a diverse range of testing requirements or standards. Engineers available to service machinery overseas. Of course, we also have agents and distributors to assist you timely in over 20 countries around the world.
This fibrograph textile testing 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.
Follows are features of digital fibrograph
- 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.
Application of Fibrograph
Fibrograph is used to determine cotton fiber mean length, upper half mean length and uniformity index by photo-electric method. 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;
Fibrograph machine complies with GB 1103, GB/T 13781 ISO 4913 , ASTM D1447etc international and retailer standards.
