ISO 16322-1 Textiles - Determination of Spirality After Washing - Test for Percentage of Spirality Change in Knitted Garments

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 16322-1 testing. ISO 16322-1 specifies a method for measuring the percentage change in wave spirality after washing in weft knit jersey garments produced on knitting machines.

Results from different procedures may not be comparable. The change in spirality is calculated from measurements taken before and after washing knitted garments.

The piping or hem of the body of a garment is stretched until the top edge of the tab or hem is flat before washing. The angle formed by the strips is measured by a line perpendicular to the upper edge of the strips or hem. This measurement is repeated after washing and the change in spirality is calculated from the difference in results.

The standard outlines the procedure and equipment required to perform this test, as well as the calculation method for determining the percent change in bale spirality. It is important for textile manufacturers and quality control professionals to use standards such as ISO 16322-1 to evaluate and maintain the quality of knitted garments, ensuring that they meet certain spirality standards even after exposure to laundering.
