ISO Launches New Test Method to Determine Material Loss from Fabrics During Washing

SafeGuardSSoftlinesFebruary 28, 2023

SG 31/23

In February 2023, the International Organization for Standardization (ISO) launched ISO 4484-1, a new test method to help the textile industry select fabrics that reduce shedding or material loss during use and laundering.


Microplastics in the natural environment are considered emerging contaminants. There is increasing scientific and public concern at the widespread presence of microplastics in oceans and the potential physical and toxicological risks posed to organisms. Microplastics can be released directly into the environment or can result from the degradation of larger pieces of plastic. Wear and washing of textiles are one recognized source of microplastics in the environment. All textiles release potentially problematic fiber fragments that shed throughout their life cycle. The fragmentation of fibers occurs based on a variety of factors and processes, such as textile construction, finishing processes, washing methods, age and fiber type. 


ISO 4481-1 Textile and textile products – Microplastics from textile sources – Part 1 Determination of material loss from fabric during washing, is a method to determine the material loss from fabrics under standardized laundering conditions. It is a modification of ISO 106-C06. The test specimen is subjected to an accelerated laundering process under appropriate conditions of temperature, time and mechanical action. The residual wash liquid is vacuum filtered, then the material loss is collected and its mass is reported. ISO 4484-1 can be used to assess both synthetic and natural material loss.


Since 2018, SGS has participated in the Cross Industry Agreement (CIA) as a research organization to develop a harmonized test method and share its knowledge of fiber fragmentation. The harmonized test method developed has been handed over to CEN for use as an official CEN standard1. In addition to SGS’s capability to conduct ISO 4484-1 tests, we have the capability to test AATCC TM212-20212. Also, SGS is approved by The Microfiber Consortium (TMC) to provide small scale TMC test services for the industry, and has been since 202034. Apart from the small-scale method, SGS also offers testing services for evaluating fiber fragmentation of finished products based on our in-house full-scale method5.


SGS has an extensive network of over 40 softlines laboratories worldwide, with a strong team of committed professionals from multi-disciplinary backgrounds. Our internationally accredited state-of-the-art testing laboratories offer a comprehensive range of physical, chemical and functional testing services for components, materials and finished products.
