The yellowing of textiles is a common problem that can occur due to various factors such as age, light, and chemical exposure. The test and interpretation of textile yellowing involve the use of different methods to identify the cause of the discoloration and determine its effectiveness. One common method is the use of a reagent such as sodium permanganate or hydrogen peroxide to create a visible reaction on the fabric. This reaction can help identify the type of dye used or the presence of metal ions in the fabric. Another method is the use of spectrophotometry to measure the absorption spectrum of the yellowed fabric, which can provide information about the type of dye used and its effectiveness. Additionally, colorimetric methods such as titration can be used to determine the concentration of a specific dye component in the fabric. In summary, the test and interpretation of textile yellowing involves the use of multiple methods to accurately identify the cause of the discoloration and determine the most effective way to remove or reduce it.

Title: A Comprehensive Analysis of the Test and Interpretation of Yellowing of Textiles

Yellowing, a common cosmetic issue in textiles, is caused by the oxidation of chromium (Cr) or iron (Fe) in textile fibers. It not only reduces the aesthetic appeal but also impacts the functional properties of the fabric, such as brightness, color fastness, and durability. Therefore, it is crucial to develop effective methods for identifying and quantifying yellowing occurrences in textile products. This article presents a comprehensive analysis of the test and interpretation of yellowing in textiles, covering various techniques, standards, and practical applications.

The first section introduces the definition and classification of yellowing, followed by the major causes of this phenomenon. The second part focuses on the development of laboratory methods for measuring yellowing intensity, including colorimetric methods, reflectance methods, and fluorescence methods. These methods are extensively reviewed and their advantages and limitations are discussed. Additionally, the relationship between yellowing intensity and other relevant properties such as dye resistance and washability is explored.

The third section presents case studies where these testing methods were employed to identify and analyze yellowing in different types of textiles, such as cotton, silk, wool, and synthetic fibers. The results of the tests are presented along with the interpretation of the findings. The fourth section discusses the application of yellowing tests in quality control systems for textile manufacturers. The significance of these tests in ensuring product compliance with regulatory requirements is emphasized.

Moreover, the impact of environmental factors such as light, humidity, and temperature on yellowing is discussed. The effects of these factors on the performance of textiles are summarized, along with suggestions for optimizing storage conditions to reduce yellowing. Finally, the potential risks associated withyellowing in textile products and ways to mitigate them are discussed. This includes the use of anti-yellowing agents and the implementation of stringent quality control measures during production.

In conclusion, this article has provided a comprehensive overview of the test and interpretation of yellowing in textiles. The laboratory methods used for measuring yellowing intensity, along with their applications in quality control systems, have been thoroughly discussed. The importance of understanding and addressing this cosmetic issue has been emphasized, as it not only affects the aesthetics of textile products but also their functional performance. By implementing appropriate measures to prevent or mitigate yellowing, textile manufacturers can ensure the consistency and quality of their products.

With the advancement of technology and increasing consumer demand for eco-friendly and sustainable products, understanding and controlling issues like yellowing in textiles hold great significance. This article serves as a valuable resource for researchers, industry professionals, and consumers alike who are involved in the textile industry.
