ICI Mace Snag Tester

About ICI Mace Snag Tester

The ICI Mace Snag Tester is a laboratory device used to evaluate the tendency of fabricsparticularly knitted and woven textilesto snag, pull, or tear during normal wear. It operates by rotating a specimen-covered drum while a weighted "mace" (studded with tungsten carbide pins) bounces on the surface, simulating accidental snagging on rough objects.

Standards

ASTM D3939 Standard Test Method for Snagging Resistance of Fabrics (Mace Test Method)

GB/T 11047 Textiles-Determination of fabrics snagging resistance-Mace test method

JIS L1058 Test methods for snag of woven fabrics and knitted fabrics

Working Principle

The cylindrical specimen is placed on the revolving drum, and  a chained  hammer is  placed on the surface of the specimen. When the drum rotates at a constant speed, the nail hammer makes random flip and bounces on the sample surface to hook the sample. The sample surface produces snagging. After the specified number of revolutions, compare with the comparison snag Lattuca for snag rating..
