ISO 105-G01 Textile discolouration under nitrogen oxide exposure

The ISO 105-G01 standard specifies a procedure for determining the resistance of textiles to discolouration caused by nitrogen oxides. This test is particularly relevant in sectors where textiles are exposed to environmental pollutants, such as automotive interiors, industrial workwear, and personal protective equipment (PPE). Discoloration from nitrogen oxide exposure can significantly impact the appearance and perceived quality of these products.

The standard outlines a method for exposing textile specimens to controlled levels of nitrogen dioxide (NO₂) in a climate-controlled chamber. The specimen is placed within this environment, where it remains for a specified duration under specific conditions. After exposure, the changes in color are measured using standardized methods. This allows for the comparison of different materials and their resistance against such pollutants.

The procedure involves several critical steps:

Selection of appropriate textile samples
Suitable placement within the test chamber
Controlled exposure to nitrogen dioxide gas
Measurement of color changes using spectrophotometric techniques
Comparison against control samples not exposed to nitrogen dioxide

The results are presented as a percentage change in color, which indicates the degree of discolouration. This metric helps manufacturers understand how their products will perform under real-world conditions where exposure to pollutants like NO₂ may occur.

This test is crucial for ensuring that textiles maintain their appearance and aesthetic appeal over extended periods, especially in environments with high levels of air pollution. By adhering to this standard, manufacturers can ensure compliance with international quality standards and protect the reputation of their products.

Why It Matters

The integrity and longevity of textiles are paramount for industries that rely on durable materials to meet demanding performance requirements. Exposure to nitrogen oxides in the atmosphere can lead to significant discolouration, which not only affects the appearance but also compromises the functionality of these products.

In automotive interiors, for example, discolouration from NO₂ exposure can result in a decline in customer satisfaction and brand reputation. In industrial environments where workers are exposed to pollutants, such changes could impact safety and comfort levels. Personal protective equipment that fails to maintain its color integrity may be less effective or even unattractive, reducing compliance with health and safety regulations.

The ISO 105-G01 standard provides a reliable method for assessing the resistance of textiles against this type of degradation. By using controlled laboratory conditions, manufacturers can simulate real-world exposure scenarios accurately. This ensures that products meet not only current but also future regulatory requirements, enhancing both product life and customer satisfaction.
