AATCC TM141-2019, Compatibility of Basic Dyes for Acrylic Fibers

Developed in 1974 by AATCC Committee RA87; reaffirmed 1976, 1977, 1980,1989, 2009, 2013; revised 1984, 2019; editorially revised 1985, 1988, 2008,2010; editorially revised and reaffirmed 1987, 1994, 1999, 2004. Technically equivalent to ISO 105-Z03.

Foreword

This test method is based on one first proposed by the Society of Dyers and Colourists. The standard dyes were chosen because: (a) they form two series encompassing the compatibility behavior of nearly all basic dyes recommended for acrylic fibers; (b) the dyes in each series are spaced to produce approximately equal visual effects; and (c) the corresponding standard dyes from both scales are compatible.

1. Purpose and Scope

1.1 In the dyeing of acrylic fibers with basic dyes, the classic parameter-e.g., the time of the half-dyeing-of individual dyes do not give a true indication of their dyeing behavior in admixture with other basic dyes.

1.1.1 Since basic dyes show virtually no migration in acrylic fibers under normal dyeing conditions, compatibility is of major importance in selecting dye combinations with optimum level dyeing behavior.

1.2 This test method is intended to determine the behavior of a dye in relation to its compatibility when applied to acrylics.
