Nail Hammer Snag Tester

The Nail Hammer Snag Tester is designed to assess the resistance of woven and knitted fabrics to snagging caused by repeated contact with pointed objects. It supports fabric development, garment quality control, and comparative testing of textile materials.

Before purchasing, confirm the applicable test standard, specimen requirements, nail hammer or mace configuration, operating speed, and test cycle settings. These details are essential for ensuring that the instrument meets the intended laboratory testing requirements.

Application

Textile and clothing industry:

It is widely used in the production of fabrics and ready-made clothes to help companies detect whether the fabric is easy to snag, so as to ensure product quality and consumer wearing experience. For example, wool sweaters, stockings and other products that are easy to snag need to be tested with this instrument during the production process.

Research field:

Researchers use it to study the influence of factors such as different fiber materials and fabric structure on the anti-snagging performance of fabrics, so as to develop better anti-snagging fabrics.

Standards

(1) GB/T 11047-2008 — Textiles — Evaluation for the Snagging Degree of Fabrics — Mace Test Method. This Chinese national standard covers the evaluation of fabric snagging using the nail hammer or mace method. It is listed as current by China's national standards information platform.

(2) ISO 25086-1:2026 — Textiles — Determination of the Snagging Resistance of Fabrics — Part 1: Mace (Spiked Ball) Test Method. This international standard specifies a method for determining the snagging resistance of woven and knitted fabrics.

(3) ASTM D3939/D3939M-26 — Standard Test Method for Snagging Resistance of Fabrics (Mace). This method evaluates snagging resistance in suitable woven and knitted fabrics made from filament yarns, spun yarns, or combinations of these yarns.

Structure and principle

Structure:

It is generally composed of multiple rotating rollers, nail hammer devices and control panels. The surface of the roller has a certain texture or coating material, and the nail hammer has sharp parts.

Principle:

The fabric sample is put on the roller. After turning on the instrument, the roller rotates, and the nail hammer continuously contacts and collides with the fabric on a specific trajectory. The sharp part of the nail hammer simulates the hooking and pulling of sharp objects on the fabric in reality. After a certain period of testing, the surface of the fabric is observed to observe the snag situation, so as to evaluate the anti-snagging performance of the fabric.
