Introduction

In-depth interpretation of GB/T 14464—2017 National Standard for Polyester Staple Fiber

1. Standard background and update overview

GB/T 14464—2017 Polyester Staple Fiber is a new revision of GB/T 14464—2008, which mainly optimizes the terminology, classification, technical requirements and test methods. The new standard introduces stricter performance indicators and advanced quality control systems to meet the needs of the modern textile industry for high-performance chemical fiber products.

Key points of standard update

New normative reference documents: GB/T 3291.3, GB/T 4146.1, GB/T 4146.3, etc.
Adjust the range of linear density of fiber classification:

Cotton type: 0.8 dtex ~2.2 dtex
Medium and long type: 2.2 dtex ~<3.3 dtex
Wool type: 3.3 dtex ~6.0 dtex

Updated technical index requirements, such as adjustment of the range of elongation at break and constant elongation strength.

2. Classification and identification of polyester staple fibers

Category	Linear density range (dtex)	Applicable scenarios
Cotton type	0.8 ~<2.2	Applicable to ordinary textiles, such as clothing and household textiles.
Medium and long type	2.2 ~<3.3	Applicable to textiles with medium strength requirements, such as industrial fabrics.
Wool type	3.3 ~6.0	Suitable for high-performance textiles such as advanced clothing and industrial composite materials.

3. Technical Requirements and Quality Control

Comparison of Technical Indicators

Item

Superior Product

First-class Product

Qualified Product

Elongation at Break

≥3.00 cN/dtex

≥2.60 cN/dtex

≥2.30 cN/dtex

Fixed Elongation Strength

≥3.80 cN/dtex

≥3.60

After adopting GB/T 14464-2017 standard, a large chemical fiber enterprise significantly improved its product quality through the following measures:

Optimize raw material management: Strictly control the quality of polyester chips to ensure that the raw materials meet the technical requirements.
Strengthen process monitoring: Set up online monitoring systems in key processes such as spinning, cutting and crimping.
Improve the detection system: Introduce advanced instruments (such as FZ/T 50027 titanium dioxide content tester) to improve detection accuracy.
Strengthen employee training: Regularly organize standard promotion and technical training to ensure that all employees understand the requirements of the new standards.
