Color 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

Features

Separate combustion and testing chambers ensure stable operation and precise control of experimental conditions.

PLC intelligent control allows setting of temperature, test duration, and alarm parameters, enabling automated operation.

Rotating sample rack design ensures uniform smoke exposure across all specimens for reliable results.

Grey scale evaluation provides intuitive, reproducible results for easy recording and analysis.

Full stainless steel construction offers corrosion resistance and easy maintenance, suitable for long-term laboratory use.
