The contamination of indoor air by formaldehyde (CH2O) is a serious hygienic problem. One of the potential sources of formaldehyde release may be furnishing fabrics. The study was conducted to evaluate the effect of ageing on textiles (17.5 months), air temperature (25-45 degrees C) and relative air humidity (RH) (45-85%) on the CH2O release rate from 6 kinds of drapers and furniture coverings. The emission was determined in small glass chambers (13.08 dm3) under controlled conditions: at one air exchange per hour and load factor 1 m2/m3. Results of these studies indicated that effect of textile ageing on CH2O emission was different for each fabric tested. The increase of temperature and RH within the ranges studied multiplied the rate of CH2O release. The drapers and covering fabrics tested, in the production of which textile dressing containing CH2O compounds was used, may remain a source of formaldehyde emission for several months.
甲醛（CH₂O）对室内空气的污染是一个严重的卫生问题。甲醛释放的潜在来源之一可能是装饰织物。本研究旨在评估老化（17.5个月）、气温（25 - 45摄氏度）和相对空气湿度（RH）（45 - 85%）对6种窗帘和家具覆盖物中CH₂O释放率的影响。在小玻璃室（13.08立方分米）中，在控制条件下测定排放：每小时一次空气交换，负载系数为1平方米/立方米。这些研究结果表明，对于每种测试织物，纺织品老化对CH₂O排放的影响各不相同。在所研究的温度和RH范围内，温度和RH的升高会使CH₂O释放率成倍增加。测试的窗帘和覆盖织物在生产过程中使用了含有CH₂O化合物的织物整理剂，可能在几个月内一直是甲醛排放源。
