pH Determination of Aqueous Extract in Textile Products

ISO 3071 - Textile - pH Determination of Aqueous Extract (Using pH Meter)

In order to have information about the processing history of textile products, the acidity or alkalinity of the textile in different forms, which is usually expressed in terms of the pH-value of the aqueous extract, “pH Determination of Aqueous Extract” is carried out. The ISO 3071 standard test method is used to determine the pH of the aqueous extract on fibers, yarns and fabrics.

As part of the ISO 3071 standard, pH, the common logarithm of the hydrogen ion concentration in an aqueous extract, is measured at room temperature via a glass electrode. measured electrometrically. The samples are put into stoppered bottles with 100 ml of extraction solution [potassium chloride solution. It is shaken mechanically for 2 hours ± 5 minutes. Afterwards, the beaker is immersed to a depth of at least 10 mm and the measurement is made.

The pH Determination of Aqueous Extract is performed by Nanolab Consumer Analysis Laboratory accredited. You can contact us for information.
