Introduction

GB/T 33794—2017 Reaction Blue K-RL Standard Interpretation

1. Background and significance of standard formulation

GB/T 33794—2017 "Reaction Blue K-RL" standard is managed by the National Dye Standardization Technical Committee and proposed by the China Petroleum and Chemical Industry Federation. The formulation of this standard aims to standardize the quality requirements, test methods and applications of Reaction Blue K-RL (CI Reaction Blue 105) to ensure the product quality and safety performance of the dye industry.

2. Comparative analysis of standard frameworks

Standard dimensions	Quality requirements	Test methods	Test indicators
Appearance	Dark blue uniform powder or granules	Visual inspection method	5.1
Strength (standard product)	≥100 points	Conventional dyeing method	5.2
pH value range	4.5~6.5	GB/T 2390	5.5
Color fastness index	Soap resistance (95℃): Level 4	GB/T 3921	5.11

Professional terms and practical application cases

Color measurement (D65 light source): used to evaluate the color difference of dyes, calculated using the CMC (2:1) color difference formula. For example, in the quality inspection of reactive blue K-RL, the color measurement results must meet the DE, DC, and DH index requirements.

Color fixation rate determination: The GB/T 2391-2014 method is used to evaluate the color fixation efficiency of dyes on fabrics. For example, in the low-salt dyeing method, the amount of auxiliary agent directly affects the color fixing effect, and the dye bath must be prepared strictly in accordance with the standard.

Implementation suggestions

Quality control:Manufacturers should establish a complete testing system to ensure that each batch of products meets the requirements of GB/T 33794-2017, especially key indicators such as appearance, strength and pH value.
Sampling and packaging:Random sampling should be carried out in accordance with the standard to ensure the representativeness of the samples, and the product name, production date and implementation standard number should be clearly marked on the packaging.
Environment and safety:During the production and use process, pay attention to prevent the flying of dye dust, and follow the visual inspection method in GB/T 6693-2009 to evaluate the dust resistance index.
