Introduction

GB/T 21294—2024 Standard Overview

GB/T 21294—2024 "Test Methods for Physical and Chemical Properties of Clothing" is an important standard in the clothing industry, used to guide the physical and chemical properties testing of clothing products. Compared with the 2014 version, this revision has comprehensively updated and optimized the test methods.

Comparison of Main Technical Changes

Category	2014 version method	2024 version improvement
Fiber composition and content test	Traditional chemical analysis method	Introducing near infrared spectroscopy (NIR) and micro-projection technology to improve accuracy and efficiency.
Color fastness test	Single test method	Add multi-dimensional tests (storage resistance, lotion staining, etc.) to more comprehensively evaluate dye stability.
Durability test	Basic strength test	Add complex environment adaptability tests such as wear resistance and resistance to humidity and heat aging to improve product life assessment.

Implementation suggestions and actual cases

Case 1: Practical application of fiber composition detection

A brand used near infrared spectroscopy (NIR) to quantitatively analyze blended fabrics. The results were highly consistent with the chemical method and the efficiency was increased by 50%.

Case 2: Color fastness test optimization

A manufacturer significantly improved the quality stability of its export products in the high temperature and high humidity environment of Southeast Asia by adding storage color fastness test.
