1.1 This practice covers a test for the characterization of certain dyeing behavior of cotton. This practice is especially applicable to raw cotton fibers, but may also be adapted to cotton yarns and fabrics.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.


This practice is not recommended for acceptance testing because the information obtained is qualitative rather than quantitative in nature.

The response of fibers to the dye mixture is indicative of the uniformity of dyeing, the probability of dyeing defects due to neps, and the difficulties to be expected from heterogeneity of fibers that differ in dyeing characteristics. In general, the red dye is retained predominantly by the thick-walled fibers and the green by the thin-walled fibers.

The color response of the specimens to the dyes in the binary mixture reflects the behavior to be expected with many other dyes. The colors from red to green may be influenced by factors such as weather during the growing period, exposure of open bolls in the field before harvest, natural color, fineness, and degree of wall development.
