Title: Determination of Formaldehyde in Textiles: Methods and Applications

Formaldehyde is a common chemical component found in textiles, which can pose health risks to consumers. Therefore, it is important to establish accurate methods for determining formaldehyde concentrations in textiles. One method involves the use of a gas chromatography (GC) system, which separates formaldehyde from other compounds and measures its concentration. This method has been widely used in industry and research settings for testing textile products such as fabrics, carpets, and upholstery. In addition to GC, other methods such as flame-ionization mass spectrometry (FIMS) and high-performance liquid chromatography (HPLC) can also be used for formaldehyde determination. The applications of these methods are diverse, ranging from quality control in the textile industry to environmental monitoring of air and water contamination. However, there are some limitations to these methods, such as the requirement for specialized equipment and the potential for false positive or negative results due to interference from other compounds. Therefore, further research is needed to develop more sensitive and reliable methods for detecting formaldehyde in textiles.

Abstract:

formaldehyde (HCHO) is a widely distributed compound in indoor air, with potential health effects on humans, particularly in the presence of elevated levels. The detection of formaldehyde in textiles is essential for ensuring consumer safety and product quality. This paper provides an overview of various methods for determining formaldehyde content in textiles, including gas chromatography-mass spectrometry (GC-MS), flame ionization detector (FID), and infrared spectroscopy (IR). Additionally, the application of these methods in different industries, such as clothing, upholstery, and bedding, is discussed. The importance of regulatory requirements, such as those established by the International Organization for Standardization (ISO) and the American National Standards Institute (ANSI), in ensuring consistent and accurate formaldehyde measurement is also highlighted. Finally, the role of ongoing research in improving the efficiency and accuracy of formaldehyde detection methods in textiles is presented.
