Formaldehyde, a toxic chemical, is usually transported and stored in the form of an aqueous solution. This solution is called formalin. Especially in foodstuffs, it is used to extend the expiration date. When the water in the formalin evaporates under reduced pressure, formaldehyde is released. This is a polymer. Formaldehyde is widely produced and used in the chemical industry. It is also used in the processing of products in the textile sector.

In general, inhalation of gaseous causes formaldehyde, drowsiness, headache, dizziness, fatigue and skin rash. Formaldehyde in liquid form is absorbed by the body through the skin. Formaldehyde emitted from home textiles and textiles can be harmful. Even deaths can occur due to sudden formaldehyde exposure.

Formaldehyde can cause cancer in humans. It is thought to be associated with lung and brain cancers and leukemia.

In the legal regulations, criteria and published standards, there are many restrictions on the use of formaldehyde in textile products. The directives issued by the European Union also have strict provisions in this regard.

Within the scope of chemical and ecological tests carried out in laboratories accredited within the scope of TS EN ISO / IEC 17025 standard from national and international accreditation organizations, some tests are carried out to determine the amount of chlorinated organic carriers in textile products. These studies are based on the following standards:

• TS EN 14181 Constant welding emissions - Quality assurance of automatic measuring systems

• ISO 14184-1 Textile - Determination of Formaldehyde - Part 1: Free and hydrolyzed formaldehyde (water extraction method)
• ISO 14184-2 Tekstil - Determination of Formaldehyde - Part 2: Free Formaldehyde (Steam Absorption Method)
• AATCC 112 Formaldehyde release from fabric - Determination of sealing method
• JSA - JIS L 1041 Test methods for some finished textiles
