Nail Hammer Snag Tester

The nail hammer snag tester is mainly used to evaluate the ability of fabrics to resist snag.

Applications

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

ASTM D3939-20: Standard Test Method for Snagging Resistance of Fabrics (Nailhead Hammer Method)

JIS L1058:2015: Test Methods for Textile Products - Snagging Resistance Test Method

Features

Multi-station configuration: Equipped with multiple rotating rollers, allowing for simultaneous testing of multiple fabric samples, thus improving testing efficiency;

Accurate scenario simulation:  Utilizing sharp pins and textured/coated rollers, the system simulates everyday scenarios of snagging and pulling of fabrics by sharp objects, resulting in test results that more closely reflect real-world usage;

High testing stability: The pins contact and collide with the fabric following a standard, specific trajectory, ensuring high consistency in force and motion trajectory, guaranteeing test repeatability;

Convenient operation: Equipped with a control panel, allowing for easy setting of test parameters and a simple operating procedure;

Multi-standard compatibility: Compatible with mainstream snagging resistance testing standards such as ASTM D3939 and JIS L1058. suitable for testing the snagging resistance performance of various woven and knitted fabrics.

Technical Parameters

Test Procedures

1. Maintain a stable voltage during use to prevent damage to the power supply.

2. Regularly clean the cork lining with a suitable cleaning solvent, such as industrial methylated spirits or trichloroethane.

3. When replacing test tubes, new test tubes must be inspected before use.

4. Regularly check that the control panel buttons and all screws are functioning correctly.

5. Clean the instrument before and after each experiment, ensuring all lint and debris are removed from the box.

6. The reference fabric should be retested every six months and compared with the initial test specimen.
