Smoke Fastness Tester
The Smoke Fastness Tester for Textiles is designed to evaluate the colorfastness of textile materials exposed to nitrogen oxides generated from burning gases, such as chemical-grade butane or city gas. The instrument simulates long-term exposure conditions in polluted environments by precisely controlling the temperature, smoke concentration, and sample rotation. Color changes are assessed using a grey scale, providing reliable data for evaluating the durability and stability of textile dyes under pollution conditions.
Application
This tester is widely used for assessing smoke fastness of various textile materials, including:
(1) Natural fiber fabrics such as cotton, linen, and silk;
(2) Synthetic fiber fabrics such as polyester and nylon;
(3) Cotton-polyester blends and functional fabrics;
(4) High-performance textiles such as industrial protective fabrics and interior decorative fabrics;
(5) Educational, research, and quality control laboratories for evaluating resistance to atmospheric pollutants.
Standards
The instrument complies with major international and national textile colorfastness standards:
(1) AATCC 23 – Colorfastness to Gas Fading (Smoke)
(2) BS 1006:1990-G02 – Textiles. Colorfastness to Smoke
(3) ISO 105-G02 – Textiles. Tests for Color Fastness. Part G02: Color Fastness to Gas Fading
(4) GB/T 11040 – Textiles. Test Methods for Color Fastness to Atmospheric Pollutants
