The textile light fastness testing machine is specially designed to test the light fastness of products. It can reproduce the damage caused by full-spectrum sunlight and rain. The DR-H301 is specially designed to meet the ISO 105 B02 textile light fastness test standard and can detect the damage caused by months or years of outdoor exposure. It is used for accelerated aging tests on textiles, dyes and outdoor leisure products.
Discover the innovative features of our Xenon Arc Light Fastness Tester, designed to meet the highest industry standards for textile durability. This state-of-the-art testing device simulates sunlight exposure on textiles, providing accurate and reliable results. With precise control over light intensity and exposure duration, our testers ensure comprehensive testing for color fastness and overall fabric quality. Perfect for manufacturers and quality control labs, enhance your textile testing protocols with our cutting-edge equipment.
Core Functions and Testing Principles：
1.1 Functional Objectives
- Simulate the fading, discoloration, gloss loss, and fiber embrittlement of textiles caused by sunlight (UV, visible light, and infrared radiation) during actual use.
- Accelerate aging through controlled testing (reducing natural exposure time from years to hours), enabling rapid prediction of a textile’s light fastness grade (e.g., ISO or AATCC standards).
1.2 Testing Principles
- Uses a xenon arc lamp as the light source (spectral range: 290nm~800nm, closely mimicking the full solar spectrum) combined with controllable temperature and humidity systems to replicate outdoor light, high temperatures, and humidity.
- Adjusts the spectral distribution via filters (e.g., simulating sunlight behind glass or direct outdoor sunlight) to meet the spectral energy requirements of different standards (e.g., ISO 105 B02 emphasizes UV + visible light, while AATCC TM16 simulates direct outdoor sunlight).
Application Scenarios：
- Textile and Apparel Industry: Evaluates the light fastness of shirts, curtains, and outdoor tents to ensure labeled durability (e.g., "no fading after 3 years of outdoor exposure").
- Home Furnishings: Tests the color stability of sofa fabrics, carpets, and curtains under indoor window light to prevent decoration quality degradation.
- Automotive Interiors: Verifies the durability of seat fabrics and headliners in car interiors (filtered sunlight + high temperature/humidity) to meet OEM standards.
- Research and Standards Development: Studies the light aging resistance of new dyes and finishes, supporting material innovation.
Box body material：
- The outer shells are all made of (t=1.2mm) A3 steel plates processed by CNC machine tools, and the surface of the shell is treated with plastic spraying, making it more smooth and beautiful.
- The inner tank is made of (SUS) 304 stainless steel plate.
- The insulation material adopts high-density glass fiber cotton and high-pressure polyurethane foam for heat insulation and preservation.
- The stirring system adopts a long-shaft fan motor and a stainless steel multi-wing impeller resistant to high and low temperatures to achieve strong convection vertical diffusion circulation.
- Double-layer high-temperature resistant high-tension sealing strips are used between the door and the box body to ensure the airtightness of the test area.
- It adopts a non-reaction door handle, making operation easier.
- The bottom of the machine is equipped with high-quality fixed PU casters.
