AATCC TM167-1986e5(2018)e

Foam generation must be controlled in dyeing equipment such as jet machines which operate with high circulation and high agitation of the dye liquor at low bath ratios.

AATCC 167-2018 provides a standard for measuring the foaming properties of disperse dyes under controlled conditions and determines the relative contribution of a single disperse dye to generate dyebath foam.
