Introduction

Core technology upgrade of the new standard

Technical dimension	2022 version	2008 version
Detection accuracy level	0.01mm level	0.1mm level
Temperature control range	±2℃/±5%RH	±3℃/±10%RH
Intensity resolution	1%FS	2.5%FS

Innovative pressure management system

According to clause 6.4 of the standard, three innovations are clarified:

Breakthrough adoption of a two-level tension control system (light tension 0.002cN/dtex/heavy tension regional setting)
Professional textile instruments must meet the dynamic continuous loading capacity of 19.6cN/dtex±0.98cN
Intelligent compensation algorithm for clamping distance (20mm basic mode is adjusted to a 16-point contact feedback system)

Intelligent data model evolution

Curl statistical optimization solutions include:

Three-dimensional fiber detection adds point cloud feature analysis (including multi-angle mirror reflection data compensation)
Automatic clustering of discrete data features (JI algorithm optimizes the iteration efficiency of the FastICA algorithm by 3 times)
Independent patented curling and wall hanging correction solution (scenario-based correction coefficient k=0.832±0.015)
