Introduction
Snagging is a phenomenon in which undesirable loops of varying sizes appear on the surface of a textile
[1] [2] [3] [4] [5] [6] [7]
product, usually as a result of the fabric catching on sharp points or objects. , , , , , , Fabrics made
of filament yarns, both textured and untextured, are most prone to snagging. However, certain fabrics made
of spun staple yarns, and certain fabric structures, can also be prone to snagging. It is important to be able
[8]
to measure the propensity of fabrics to snagging (alike ISO 12945-4 for pilling, fuzzing and matting) so
that fabrics with the lowest propensity to snagging can be selected for making garments.
[9]
A study carried out in France (called "DurHabi", related to the lifespan of textile garments, 2022 ) showed
that the criterion based on the snagging resistance of this document is more discriminatory for sport-wear
(tee-shirts, trousers, etc.) and for ready-made garments made of knitted fabrics (dresses, skirts, etc.) than
ready-made garments made of woven fabrics.

3.1
snag
undesirable loop on the surface of a woven or knitted fabric
4 Principle
A tubular test specimen is placed on a cylindrical drum. Then a mace (spiked ball) bounces randomly against
the rotating test specimen. Snag(s) are produced to a degree affected by a variety of factors. Snagging
resistance is assessed by visual comparison of the snagging with photographic standards illustrating
different levels of snagging or with fabric standards.
The observed resistance to snagging is reported on a scale ranging from 5 (no or insignificant snagging) to
1 (very severe snagging).

5.1 Mace snag tester, which shall be provided with rotating cylindrical drum, with a diameter
-1
of (82,0 ± 0,5) mm, at (60 ± 2) min , fitted with felt sleeves, mace (spiked ball) attached to a chain or a
string, circumventing a guide rod, with a diameter of (10,0 ± 0,5) mm (see Figure 1), and controlled by a
predetermined electronic counter.
The axis of the guide rod is eccentric to the axis of the rotating cylindrical drum by (25 ± 5) mm horizontally
and (100 ± 5) mm vertically (see Figure 1).
The characteristics of the mace (spiked ball) are:
— ball diameter of (32,0 ± 0,5) mm;
— mace (spiked ball) mass of (160 ± 10) g;
