Product Detail

Yarn and Sliver Evenness Testing Equipment GT-A14EH

Product Introduction

The Yarn and Sliver Evenness Tester is a cutting-edge testing instrument designed for textile laboratories. It is used to test the unevenness and hairiness variation of yarns, and is suitable for pure and blended slivers of cotton, wool, silk, flax, and synthetic staple fibers. It is of great significance for improving and ensuring yarn quality.

Feature

Data calculation by computer. Windows-based monitoring software with full-Chinese GUI, high integration and stability.
Real-time test of CV%, U%, H, SH values and 12-grade imperfections.
Multiple graphical indicators (variation-length, unevenness, spectrogram, linear density-frequency distribution) for easy yarn quality evaluation.
340-channel continuous evenness spectrogram for precise process fault analysis.
DR% value, scatter plot, DR curve and △DR(Lc) for random unevenness analysis, predicting fabric appearance after weaving.
Statistical system generates daily/monthly/quarterly/annual reports and distribution graphs for long-term trend monitoring.
Expert system assists in process fault analysis and spinning performance evaluation.
Storable unevenness curves for in-depth analysis.
Electromagnetic tensioner with software-controlled tension.
Servo-driven transmission system, low noise and high reliability.
Auto-retractable rollers reduce wear and stabilize yarn running.
Auto zeroing function improves efficiency and simplifies operation.
High data consistency with traditional test methods.
