Vibration Fiber Fineness Tester
Product Introduction & Applications
The Vibration Fiber Fineness Tester operates based on the string vibration principle. By measuring the natural vibration frequency of a fiber with known vibration length and pre-tension, the instrument automatically calculates the linear density (fineness) of a single fiber.
It offers a fineness measurement range of 0.6–40 dtex and performs tests quickly, making it suitable for evaluating fiber mass distribution uniformity, including linear density unevenness.
This instrument not only measures fiber fineness but can also test single fiber strength, initial modulus, and breaking work when used together with the instrument’s tensile force system. Test results such as single value, average value, and coefficient of variation can be displayed directly and printed via an external printer.
It is widely used in:
Chemical fiber production enterprises
Textile manufacturers
Quality inspection organizations
Scientific research institutions

FAQ
1. What is the measurement principle of the vibration fiber fineness tester?
It uses the vibroscope principle: the natural vibration frequency of a fiber under known tension and length is measured, then converted into fineness (linear density).
2. What types of fibers can be tested?
It is suitable for synthetic fibers, chemical fibers, staple fibers, and other single-fiber materials that can be clamped and tensioned.
3. Can the tester measure linear density unevenness?
Yes. It can calculate coefficient of variation (CV%), reflecting mass distribution uniformity of fibers.
4. Does the instrument support report printing?
Yes. An external printer can output all test results instantly.
5. Is it applicable for both production and laboratory use?
Absolutely. It is widely used by fiber manufacturers, textile mills, quality inspection labs, and research institutes.
