The International organization for Standardization (ISO) has launched new test standard ISO 4484-1:2023 (Textiles and textile products — Microplastics from textile sources — Part 1: Determination of material loss from fabrics during washing).

A new test standard, which is applicable to textiles and textile products, was published in February 2023, ISO 4484-1:2023 (Textiles and textile products — Microplastics from textile sources — Part 1: Determination of material loss from fabrics during washing).

This test method is designed to collect material loss from fabrics under the specified laundering test conditions to achieve results that are both comparable and accurate. As outlined in the scope of the standard, there is no direct correlation to material loss during domestic and commercial laundering. The method is designed to assess material loss of all types.

During testing, the test specimen is subjected to an accelerated laundering process under standardized conditions of temperature, time and mechanical action. The resultant wash liquor is vacuum filtered. Material loss is assessed gravimetrically to approximate material loss during simulated domestic laundering.

The ratio of the mass of the material loss by the test specimen mass is reported.

Important notes:

Manufacturers of textile articles should be able to make knowledgeable decisions about the type of fabric to use to reduce/minimize shedding, as well as to test different methods of manufacture that minimize material loss during laundering, based on the utilization of this test standard.
