Introduction
Interpretation of the standard for determination of water saturated solubility of fiber digital inkjet dyes
1. Background and significance of standard formulation
With the widespread application of digital inkjet technology in the field of textile printing and dyeing, the requirements for dye performance are increasing. The formulation of GB/T33076-2016 standard aims to standardize the determination method of water saturated solubility of fiber digital inkjet dyes and provide a scientific basis for product quality control and research and development.
2. Technical framework of the standard
| Standard dimensions | Specific content | Scope of application |
|---|---|---|
| Determination principle | Calculate the dye concentration based on the absorbance value and determine the saturated solubility. | Applicable to digital inkjet reactive dyes and acid dyes. |
| Instrument requirements | Including analytical balance, spectrophotometer, centrifuge and other precision equipment. | Used under laboratory conditions, must comply with GB/T2374-2007 requirements. |
| Determination steps | Including solution preparation, saturated dissolution, absorbance determination and data calculation. | Strictly control the experimental temperature and operation process. |
3. Standard Implementation Suggestions
Experimental Condition Control: Ensure that the laboratory temperature is within the range of 20℃±2℃ and use grade 3 pure water.
Instrument calibration: Regularly calibrate key equipment such as analytical balances and spectrophotometers to ensure measurement accuracy.
Data recording and processing: Record absorbance values and solution concentrations in detail, and make rounding and determinations according to GB/T8170-2008.
