Brief Introduction
ICI Mace Snag Tester is designed for rapidly determining the tendency of fabrics to snag (pull yarn loops from the fabric) in normal wear.
The ICI Mace Snag Tester completes with viewing cabinet and comparison photographs for different fabric constructions. Provided with 4 rotating test cylinders fitted with sleeves of test fabric, mace balls with tungsten carbide points and controlled by a predetermined electronic counter.
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..
