ICI Mace Snag Tester

Introduzione
ICI Mace Snag Tester is suitable for the snagging performance test of  knitted fabrics and woven fabrics in outwear as well as other fabrics easy to snag , especially for chemical fiber filament yarn and its deformation yarn products. It can quickly detect the fabric snagging tendency under normal wearing condition (namely snagging the yarn out from the fabric).
The instrument is equipped with an observation box and the comparison pattern card with different fabric structure. It is equipped with four test rolls ( for putting on the fabric to be tested). The mace ball is a tungsten carbide head and is controlled by a predetermined electronic counter.
 
Principio di funzionamento
 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..
