Released Formaldehyde by Steam Distillation Method
topic
Released formaldehyde testing suspends a fabric specimen in a sealed jar above water at 49 degrees Celsius for 20 hours under controlled humidity, collecting formaldehyde vapour released from resin cross-links into the water layer and quantifying by acetylacetone colorimetry; the AATCC 112 jar method simulates formaldehyde release during garment storage and packaging at elevated temperature.
Role
Measures the volatile formaldehyde release potential from durable press finished garments during storage and distribution, predicting consumer inhalation exposure when opening sealed textile packaging and establishing compliance with Japanese domestic formaldehyde regulations governing textile products sold in Japan.
