The ISO 3071 standard outlines a method for testing the pH of textile fabrics. The test involves measuring the pH of a 10% aqueous extraction of the fabric, which is meant to simulate the conditions in which the fabric will be used (e.g. in contact with skin). The pH is measured using a pH meter or a pH indicator paper. The pH range for textiles is generally between 4 and 9.
A fabric pH test is important because the pH of a fabric can affect the comfort and durability of the fabric as well as the colorfastness and ease of dyeing. A low pH (acidic) can cause itching and irritation of the skin, while a high pH (alkaline) can cause the fabric to become stiff and brittle. Additionally, a fabric with a high pH can cause dyes to fade or change color, making the fabric appear dull and discolored. By measuring the pH of a fabric, manufacturers and textile researchers can ensure that the fabric is within a suitable pH range for use and that the fabric will maintain its color and quality over time.
