Introduction

Core changes in the standard revision

Technical dimension	2008 edition	2019 edition	Significance of the revision
Grading	Second-grade system	Excellent/first-grade/qualified three-grade system	In line with the international grading system
Twist control	Ply deviation ±4.0%	Excellent products are tightened to ±3.5%	Improve the uniformity of high-end yarns
Color fastness index	Divided into wool/non-wool interlining	Divided by 30% animal hair content	The testing method is more scientific

Detailed explanation of key technical requirements

Physical index control system

The new standard divides yarn into three categories according to count: high-count yarn (≥70 public count), medium-count yarn (32-70 public count), and low-count yarn (≤32 public count), among which:

The requirement for linear density variation coefficient has been increased most significantly, and the single yarn superior product has been tightened from 2.5% to 2.0%
Newly added Warp-only Pure wool yarn breaking strength agreement standard

Color fastness innovation requirements

Case: The color fastness requirement for dark-colored products to dry cleaning was raised from level 3-4 to level 4. A cashmere blended spinning company improved the dyeing process and used a new type of fixing agent to increase the compliance rate from 72% to 95%.

Implementation suggestions

Increase pre-inspection of fiber content in the raw material testing stage to ensure compliance with GB/T 29862
The twist control equipment needs to be upgraded to an electronic twist meter
Establish a color fastness risk warning mechanism and increase the frequency of intermediate inspections for dark-colored products

Analysis of standard evolution

This revision deleted the outdated equivalent regain calculation clause and changed the yarn defect detection from the artificial blackboard method to the capacitive instrument method (FZ/T 01050), reflecting the trend of textile testing technology towards intelligence.
