LFY-101 Automatic Yarn Comprehensive Testing System

Main purpose
The automatic yarn comprehensive testing system is mainly used for testing yarn diameter, yarn count, yarn hairiness, line dry uniformity, and yarn defects (coarse and detailed).
Instrument features
It is controlled by a computer, has a full Chinese graphical interface, has a high degree of automation, is easy to operate, and the relevant parameters for testing, such as sample length, yarn running speed, hairiness length, yarn defect classification, can be set by the user on the computer screen through the keyboard as needed. The instrument can intuitively display dynamic test data and yarn shape curves on the computer screen. The test data can be saved and can also be printed in report form for the test report. It also has a historical test data query function. Software upgrade is provided for free.
