For Shrinkage and Durability Testing

Makeweights, also known as ‘ballast’ or ‘loading fabrics’ are used to make up the load in washing, dry cleaning, dimensional stability, drying or durability tests.

We manufacture Makeweights to the precise specifications demanded by various ISO standards. We also supply American Makeweights as specified in AATCC Test Methods.



We control the quality of our makeweights at every stage of manufacturing. Cotton ballast, wool ballast and polyester ballast.
