Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 21875-2008 "Determination of dye lift force", compared with GB/T 21875-2008, in addition to editing
The main technical changes are as follows.
- "Terminology and Definitions" (Chapter 3 of the.2008 edition);
--- added the "principle" (see Chapter 3);
- the instrument and material are divided into two chapters of materials and reagents, instruments and equipment (see Chapter 4 and Chapter 5, Chapter 4 of the.2008 edition);
--- delete the results of the method to determine the content (see the.2008 version of 5.1);
- the method of determining the determination of the measurement point and the method of determining the measurement point of the padding method (see 6.2.1,.2008, 5.2);
- modified the expression of the staining method (see 6.2.2,.2008, 5.2.1);
- increased dyeing with reactive dyes (see 6.2.2.14);
--- modified the expression of the dyeing operation (see 6.2.3), 5.2.2 of the.2008 edition);
- modified the formulation of the results of the determination of the results (see 6.3, 5.2.3 of.2008);
--- modified the drawing example (see 6.4.4,.2008 version 5.2.4);
--- modified the contents of the test report (see Chapter 7, Chapter 6 of the.2008 edition).
This standard is proposed by the China Petroleum and Chemical Industry Association.
This standard is under the jurisdiction of the National Dye Standardization Technical Committee (SAC/TC134).

3 principle
The color depth of each dyed fabric (Integ value) was determined by staining the specific fabric with a series of different dyeing depths. To stain
Depth is the abscissa, and the depth value (Integ value) is the ordinate curve showing the lifting force of the dye.
