What is ISO 5532:2018?

ISO 5532:2018, officially known as "Fibres and Yarns - Determination of Hairiness - Capacitance Method" is an international standard developed by the International Organization for Standardization (ISO). It provides a guideline for measuring hairiness in fibres and yarns using the capacitance method.

of the Standard

The ISO 5532:2018 standard specifies the test method for determining the hairiness of fibres and yarns. Hairiness refers to the presence of loose fibers or protruding ends on the surface of a textile material, which can impact its appearance, feel, and performance.

The standard outlines the use of a capacitance-based measurement system, which involves passing the specimen through a capacitive sensor at a constant speed. The sensor measures the changes in capacitance caused by the presence of hairiness on the surface of the material.

Importance of Hairiness Measurement

The measurement of hairiness is crucial in the textile industry as it directly affects the quality and performance of textile products. Excessive hairiness can lead to issues such as increased pilling, reduced fabric strength, and decreased dye absorption ability. By quantifying hairiness, manufacturers can assess and control the quality of their materials, ensuring that they meet the desired specifications and customer expectations.

ISO 5532:2018 provides a standardized method for measuring hairiness, allowing for consistent and reliable comparison of different fibres and yarns. This enables manufacturers to make informed decisions regarding material selection, process optimization, and product development.

Benefits and Applications

The implementation of ISO 5532:2018 brings several benefits to both manufacturers and end-users of textile products. Firstly, it allows manufacturers to enhance their quality control processes by providing a standardized and objective measurement of hairiness.

Furthermore, the standard facilitates product development by enabling manufacturers to compare different materials and make informed decisions about their suitability for specific applications. Whether it's selecting yarns for soft and smooth fabrics or fibers for durable upholstery, the measurement of hairiness plays a critical role in achieving the desired characteristics.

For end-users, ISO 5532:2018 ensures that the textiles they purchase meet the expected quality standards. Garments with controlled and optimized hairiness are more comfortable to wear, have better durability, and exhibit improved aesthetic appeal.
