Protective Clothing Tests

Determination of pH of Aqueous Extract (ISO 3071)

Liquid permeability properties of protective clothing by the International Standards Organization (ISO) and ISO 3071 standard has been designed to describe the test methods. This standard has been published in our country by the Turkish Standards Institute (TSE) with the following title: TS EN ISO 3071 Textile - Determination of pH in aqueous extract.

Determination of pH of Aqueous Extract (ISO 3071)

The said standard discloses a method for determining the pH of the aqueous extract of textiles. The method here can be applied to textiles in any form of fiber, yarn or fabric. In this standard, a simple extraction procedure using water is recommended to measure the pH of non-aqueous solutions containing water-immiscible solvents. During the test, water is added to the extract and mixed thoroughly with the sample. After reaching an equilibrium, the solvent phase is separated and then the pH of the water phase is measured.

Liquids are used as solvents to form solutions. The most common solvent is water. Some examples of solvents other than water are alcohol and oil. These are often mixed with water or some other non-aqueous solvents to create mixed solvents suitable for certain applications in chemical research or industrial processes.

The pH value in textile products is made to determine the acid and alkali contents remaining in the fabrics. A relatively higher requirement is needed for the pH value of fabrics in direct contact with the skin. If this value is controlled between weak acidity or neutrality, it will not adversely affect the skin. The test method described here is for determining the pH value of wet processed textiles. During the tests, some chemical compounds affecting the pH value are extracted from the textile sample, collected as a water extract, and then measured with a special device.

Within the scope of protective clothing testing services, our organization also provides testing services for the determination of the pH value of the aqueous extract (ISO 3071).
