Yarn Hairiness Tester

Yarn Hairiness Tester is a precision textile electronic instrument. It is used to measure and analyze the yarn hairiness index and diameter index. It can automatically test and statistically analyze the length, quantity and distribution of the hairiness in the yarn, the size and unevenness of the diameter, and can simulate an electronic blackboard. This instrument is suitable for testing short-fiber yarns and sizing yarns

Main Features

• Uses image vision technology with an imported high-resolution CCD digital camera, ensuring good data repeatability.
• Adopts the projection counting method and external positioning to comply with national textile industry standards.
• Measures the hairiness index while simultaneously detecting yarn diameter and diameter variation coefficient.
• Features an automatic system that adjusts yarn pre-tensioning.
• Supports multi-speed testing with a maximum speed of 100 m/min, delivering high test efficiency.
• Includes a specially designed rubber roller to prevent entanglement.
• Provides an electronic blackboard function for easy monitoring and display.

Why Choose the Yarn Hairiness Tester?

The Yarn Hairiness Tester is essential for textile manufacturers and labs focused on yarn quality improvement. Since hairiness and diameter unevenness affect fabric performance, this tester provides accurate data compliant with standards like ASTM D 5647. For example, it evaluates short-fiber and sizing yarns, ensuring consistent quality for weaving. Its high-resolution imaging and multi-speed options enhance testing efficiency, while the anti-entanglement device prevents disruptions.
