Product Detail

Automatic Yarn and Sliver Evenness Tester GT-A14HD

Product Introduction

Application:

Yarn Evenness Tester is a precision textile testing instrument integrating optical, mechanical, electronic and pneumatic technologies. It is used to test yarn linear density unevenness, surface hairiness and other indicators for comprehensive evaluation of yarn quality, and serves as essential testing equipment for quality inspection and control in textile manufacturers. It is applicable to pure-spun and blended yarns made from cotton, wool, silk, linen and staple chemical fibers.

Feature

Adopts both capacitive and photoelectric detection technologies to simultaneously measure linear density unevenness (mass variation) and yarn hairiness, enabling a more comprehensive and scientific evaluation of yarn quality.
Fully automatic measurement for spun yarns.
Real-time measurement of CVm%, Um%, H, SH and all types of fault values.
Supports 6 ranges of DR values and 3 ranges of △DR values to facilitate users’ analysis of abnormal long thick places and abnormal long thin places.
The yarn drawing system adopts a high-speed dual active drive mechanism, with a maximum testing speed of 800 m/min.
User-friendly interface; users may customize the colors of displayed graphs according to personal operating habits.
Generates unevenness curves of yarn evenness and hairiness, spectrograms, variance-length curves, linear density frequency distribution diagrams, and offset-threshold graphs.
The spectrogram is equipped with 170 channels, helping users accurately locate faults or defective sections.
Built-in expert analysis system for automatic diagnosis and analysis of each production process.
Equipped with special software for slub yarns to realize effective testing and analysis of slub yarn products.
