必须在染色设备（如喷射机）中控制泡沫的产生，喷射机在低浴比下高循环和高搅拌染色液。AATCC 167-2018提供了在受控条件下测量分散染料发泡性能的标准，并确定了单个分散染料在生成染料浴泡沫中的相对贡献。

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.
