In the ISO 14389 standard developed by the International Standards Organization (ISO), a test method for determining phthalates in textile products is defined by the gas chromatography - mass spectrometry (GC-MS) method with a mass selective detector. This standard is applied to textile products where there is a risk of the presence of certain types of phthalates.
Phthalates are generally used as plasticizers in polymers. Phthalates pose a problem for textile manufacturers and retailers during their use in motifs, coated fabrics, plastisol prints, buttons and similar uses.
In fact, the use of phthalates is a controversial issue, as studies have shown a large number of high levels of phthalates hormonal activity. Studies on rodents containing large amounts of phthalates have revealed that it damages the liver, kidneys, lungs and developing testicles. Because of these potential effects as endocrine disruptors, some of the phthalates are reproductively toxic. The use of these phthalates has been restricted in developed countries, especially in European Union countries.
The ISO 14389 standard requires the use of substances and procedures that are harmful to health if adequate precautions are not taken. This standard only expresses technical compliance and does not relieve the user from legal obligations related to health and safety at any stage.
For the purposes of this standard, plasticized or softened material refers to plastic material that has been treated with chemicals to make it more flexible. These chemical materials are phthalates. Major examples of plastic materials are coating, pigment printing binder and the like. A general treated textile product is a continuously finished, coated or printed textile product. A locally processed textile product is a discontinuous finished, coated or printed textile product. The representative sample is the sample obtained by mixing all the different machined parts and colored parts.
While testing, phthalates are extracted from the textile sample with an ultrasonic generator with tetrahydrofuran. Since the plastic polymer is partially or completely dissolved, phthalate extraction is followed by precipitation of the dissolved polymer using the appropriate solvent.
Among the numerous tests, measurements, analyses, and evaluations our organization provides for businesses in various sectors, we also offer tetrahydrofuran testing services for the determination of phthalate content in textile products under the ISO 14389 standard, utilizing a trained and expert staff and advanced technological equipment.
