Introduction

GB/T 35934-2018 Standard Overview

This standard "National Standard of the People's Republic of China GB/T 35934—2018" specifies the test method for cotton dyeing performance, and is applicable to all types of cotton fibers (except colored cotton), as well as natural yarn and grey fabric made of cotton fibers. The standard focuses on solving the problem of uneven dyeing caused by differences in cotton fiber maturity, and provides scientific testing methods and evaluation criteria.

Background and significance of standard formulation

During the production process, raw cotton is affected by factors such as origin, season, and environment, which will produce fiber quality differences, thereby affecting dyeing performance. Based on the correlation between cotton fiber maturity and dyeing color difference, GB/T 35934-2018 standard establishes the grading level of dyeing color difference, providing important guidance for textile enterprises to purchase cotton raw materials.

Comparative Analysis of Standard Frameworks

Chapter	Content Overview	Keyword Extraction

Core clauses and implementation recommendations

Detailed interpretation of the test method

7.1 Sample preparation:Evenly extract 3g~4g of loose fibers from the laboratory sample, sandwich them between the upper and lower gauze, and sew them to form a 10cm×10cm combined sample.

Instrument requirements

Colorimeter (GB/T 3979):Used to measure the color difference after dyeing, it must meet the requirements of standard light source D65 (color temperature 6500K).
