Flammability Test in Textile: An In-depth Analysis of LISUN ZY-3 Needle Flame Test

Abstract
Flammability test in textile is a crucial assessment to ensure textile products meet fire safety standards. The LISUN ZY-3 Needle Flame Test provides an effective method for evaluating textile materials’ resistance to ignition by small flames. This article discusses the significance, methodology, and results of using the LISUN ZY-3 Needle Flame Test in textile flammability testing. A comparative table of flammability performance for different textile types is also included to highlight the practical implications of this test.

1. Introduction
Textile materials are widely used in everyday life, including clothing, home furnishings, and industrial applications. Ensuring their fire safety is a critical concern in textile manufacturing. The flammability test in textile helps manufacturers assess the risk of textiles catching fire and contributing to flame spread. One of the most effective and widely used tests for this purpose is the LISUN ZY-3 Needle Flame Test, which simulates the impact of small flames on textiles.

This article provides a detailed overview of the LISUN ZY-3 Needle Flame Test, its working principles, applications, and the importance of flammability testing in textile industries.

2. Importance of Flammability Test in Textile
Flammability tests in textile materials are essential for:

• Ensuring Consumer Safety: Preventing fire hazards in clothing, upholstery, and curtains.
• Regulatory Compliance: Meeting national and international fire safety standards (ISO 11925-2, UL 94, etc.).
• Product Quality Control: Enhancing the durability and safety of textiles.
• Reducing Fire-Related Risks: Lowering the risk of fire accidents in public and private spaces.

3. LISUN ZY-3 Needle Flame Test: Overview

The LISUN ZY-3 Needle Flame Test is an advanced instrument designed to assess the flammability of textiles by exposing them to a controlled flame for a specific duration. It is widely used for safety testing in textiles, electronics, and plastics.

3.1 Features of LISUN ZY-3 Needle Flame Test

• Compliance with Standards: Conforms to IEC 60695-11-5, ISO 11925-2, and UL 94 standards.
• Adjustable Flame Parameters: Allows precise control over flame height and exposure duration.
• Automatic Ignition System: Ensures consistency and accuracy in testing.
• Real-Time Data Recording: Facilitates detailed analysis of flammability characteristics.
• Safety Mechanisms: Includes automatic shut-off and fire containment features.

3.2 Test Procedure

• Sample Preparation: Textile samples (100mm x 50mm) are conditioned under controlled temperature and humidity.
• Flame Application: A 12mm flame is applied to the textile for a defined period (e.g., 5, 10, or 30 seconds).
• Observation: The burning behavior, flame spread, and afterflame time are recorded.
• Data Analysis: The results are compared with safety thresholds to determine the textile’s flammability rating.

4. Experimental Data and Analysis

A series of flammability tests in textile were conducted using the LISUN ZY-3 Needle Flame Test on different fabric types. The table below presents the results:

Table 1: Flammability Test Results of Different Textile Materials

Textile Type	Flame Exposure Time (s)	Afterflame Time (s)	Char Length (mm)	Flammability Rating
Cotton Fabric	10	3	60	High Risk
Polyester Fabric	10	1	30	Medium Risk
Wool Fabric	10	0	20	Low Risk
Nylon Fabric	10	2	40	Medium Risk
Flame-Retardant Cotton	10	0	15	Very Low Risk

4.1 Interpretation of Results

Cotton Fabric exhibited the highest flammability risk due to its prolonged afterflame time and significant charring.
Polyester and Nylon Fabrics showed moderate risk, with shorter afterflame times and reduced char length.
Wool Fabric demonstrated excellent fire resistance, with no observable afterflame.
Flame-Retardant Cotton performed best, with minimal charring and no afterflame, making it ideal for fire-resistant applications.

5. Conclusion
The flammability test in textile is essential for ensuring fire safety in textile products. The LISUN ZY-3 Needle Flame Test provides a reliable and standardized method for evaluating the fire resistance of textiles. Experimental results confirm that textile composition significantly affects flammability, with flame-retardant fabrics offering superior protection.

Manufacturers should integrate rigorous flammability tests in textile production to enhance product safety and compliance with international fire safety regulations.
