The ICI Mace Snag Tester is a laboratory device used to evaluate the tendency of fabrics—particularly knitted and woven textiles—to 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..

FAQ

1.What is the ICI Mace Snag Tester?

The ICI Mace Snag Tester is a specialized device used to assess the snagging resistance of fabrics. Commonly used in the textile and apparel industries, this tester evaluates how materials react when subjected to potential snagging conditions, ensuring durability and quality in finished products.

2.How does the ICI Mace Snag Tester operate?

The ICI Mace Snag Tester operates by simulating snagging actions on fabric samples. It employs a rotating mace that has a set of predetermined angles and speeds, which help to replicate real-world snagging scenarios. After the testing process, the fabric samples are examined to identify the extent of damage, allowing manufacturers to evaluate the performance of their textiles.

3.What types of fabrics can be tested with the ICI Mace Snag Tester?

The ICI Mace Snag Tester can be used on a wide variety of fabrics, including woven, knitted, and non-woven materials. It is particularly useful for evaluating garments, upholstery, and other textiles that may experience snagging in everyday use, helping manufacturers ensure they meet quality standards.

4.Why is snag testing important in the textile industry?

Snag testing is crucial in the textile industry because it helps manufacturers identify vulnerabilities in fabric designs that could lead to damage in finished products. By understanding snag resistance, companies can enhance the durability and longevity of their textiles, ultimately improving customer satisfaction and reducing returns.

5.Is training required to use the ICI Mace Snag Tester?

While the ICI Mace Snag Tester is designed to be user-friendly, it is recommended that operators undergo proper training to ensure accurate and consistent results. Training often includes understanding machine operation, sample preparation, and the evaluation of test outcomes, which can be provided by the equipment supplier or through industry workshops.
