Product Detail

Yarn Evenness Tester GT-A14-4000 | Textile Quality Control Testing Machine

Product Introduction

GT-A14-4000 Evenness Tester is a precision textile testing instrument integrating optical, mechanical, electrical and pneumatic technologies. It is used to test yarn evenness, linear density variation, diameter and its fluctuation, surface hairiness, impurity size and content, so as to comprehensively evaluate yarn quality. As essential testing equipment for textile enterprises in quality inspection and control, it is applicable to pure and blended yarns of cotton, wool, silk, linen and staple synthetic fibers.

Feature

Adopts dual capacitive and photoelectric detection to simultaneously test mass and diameter unevenness for scientific and comprehensive yarn quality evaluation.
Fully automatic measurement with automatic yarn feeding, groove switching and roller reciprocation.
Real-time detection of CVm%, Um%, H, SH, D, CVD%, graded yarn faults, as well as size and content of impurities and dust.
Equipped with 6-level DR and 3-level △DR values for analysis of abnormal long thick and thin places.
High-speed dual active yarn traction system, with a maximum testing speed of 800m/min.
Provides multiple analysis graphs including evenness and hairiness curve, spectrogram, variance-length curve, linear density frequency distribution curve and offset-threshold graph.
170-channel spectrogram enables accurate judgment of equipment faults and yarn defects.
Built-in 3D fabric simulation system, which automatically generates yarn profile, electronic blackboard, woven and knitted fabric renderings with adjustable fabric structures.
Integrated expert analysis system for automatic diagnosis and analysis of each production process.
Supports slub yarn testing, detecting slub length, spacing, multiple and other core indicators.
Impurity detection function outputs average size, per-kilometer and per-gram content and distribution graph of impurities and dust.
