XJ129 Nep and Short fiber Tester is a rapid automatic instrument of measuring nep numbers and short fiber contents of raw cotton or cotton sliver, shows nep classification and linter index at same time. It is applied to textile enterprises, cotton testing departments, cotton trading organizations, cotton breeding departments, and institutes, ect units which need to measure nep and short fiber index of cotton.
1. Testing sample of nep is large (5g or 10g), and the testing result is more typical.
2. Short fiber test can put sample in level and line automatically of one side which achieves real effective measure to short fiber.
3. Creatively devised carding mechanism.
4. Cotton ribbon is made to even thickness that improves consistency and accuracy of short fiber test.
5. Function of diagnosing is comprehensive, and use is convenient.
6. It has function of span length and free choosing short fiber index.
