AATCC 206-2020适用于可能含有游离或水解甲醛的可湿（非疏水）织物，尤其是用含有甲醛的化学品整理的织物。它提供了水提取过程，并对提取的游离和水解甲醛量进行了后续比色分析（见注释14.1和第3.1节以及第3.2节）。

AATCC 206-2020 is applicable to wettable (non-hydrophobic) textile fabrics that may contain free or hydrolyzed formaldehyde, particularly fabrics finished with chemicals containing formaldehyde. It provides a water extraction process and a subsequent colorimetric analysis of the amount of free and hydrolyzed formaldehyde extracted (see note 14.1 and Section 3.1 and Section 3.2).
