Textiles 45 degrees burning: a new method for testing the flame retardant performance of textiles
Textiles 45 degrees burning is a new method for testing the flame retardant performance of textiles. This method allows for the assessment of the resistance of textiles to flame at 45 degrees Celsius. The test measures the time taken for the flame to spread over the entire surface of the textile sample and provides an indication of the flame retardant performance. This method is particularly useful for textiles intended to be used in environments where fire safety is important, such as clothing, upholstery, and interior design materials. The aim of this method is to ensure that the textiles tested meet the necessary flame retardant standards and are safe for use in such environments.
Abstract:
This paper introduces a new method for testing the flame retardant performance of textiles, namely 45 degrees burning. The method is based on the observation of the burning behavior of textiles at 45 degrees angle from the horizontal plane. The results obtained from this method can provide important information about the flame retardant performance of textiles, including their tendency to spread flames, the rate of burning, and the formation of char residue. This method can be applied to a wide range of textile materials, including cotton, polyester, nylon, and so on. The results obtained from this method can also be used to evaluate the effectiveness of flame retardant treatments applied to textiles.

1、Introduction
Textiles are widely used in various fields due to their good performance in physical, chemical, and thermal aspects. However, the flame retardant performance of textiles is crucial in many applications, such as clothing, interior decoration, and aviation industry. Therefore, it is essential to evaluate the flame retardant performance of textiles accurately and reliably. The traditional methods for testing the flame retardant performance of textiles mainly include vertical burning test (VBT), horizontal burning test (HBT), and limited oxygen index (LOI) test. However, these methods have some limitations, such as low reproducibility, high test temperature, and complex operation procedure. In order to solve these problems, this paper proposes a new method for testing the flame retardant performance of textiles, namely 45 degrees burning.
2、45 degrees burning method
The 45 degrees burning method is based on the observation of the burning behavior of textiles at 45 degrees angle from the horizontal plane. The specimens are clamped at one end and suspended at an angle of 45 degrees to the horizontal plane using a wire. The specimens are then exposed to a horizontal flame source and the burning behavior is observed and recorded. The results obtained from this method can provide important information about the flame retardant performance of textiles, including their tendency to spread flames, the rate of burning, and the formation of char residue. This method can be applied to a wide range of textile materials, including cotton, polyester, nylon, and so on. The specimens can be tested individually or in bundles, depending on the specific needs of the user.
3、Experimental setup and procedure
The experimental setup includes a horizontal flame source, a specimen holder, and a data acquisition system. The horizontal flame source is used to generate a stable horizontal flame for burning the specimens. The specimen holder is designed to clamp the specimens at one end and suspend them at an angle of 45 degrees to the horizontal plane using a wire. The data acquisition system is used to record the burning behavior of the specimens, including flame spread tendency, burning rate, and char residue formation. The procedure involves clamping the specimens in the specimen holder and suspending them at an angle of 45 degrees to the horizontal plane. The specimens are then exposed to the horizontal flame source and the burning behavior is observed and recorded by the data acquisition system. After the test is completed, the specimens are removed from the specimen holder and their weight and length are measured for further analysis.
4、Results and discussion
The results obtained from the 45 degrees burning method can provide important information about the flame retardant performance of textiles. Figure 1 shows the flame spread tendency of different textile materials tested using this method. It can be seen that different materials have different flame spread tendencies. Figure 2 shows the burning rate of these materials as a function of time. It can be observed that the burning rate varies with time for different materials. Figure 3 shows the char residue formation on these materials after burning. It can be seen that some materials form more char residue than others after burning. These results can help evaluate the effectiveness of flame retardant treatments applied to textiles by comparing them with standard reference values or other test methods.
5、Conclusion
In conclusion, this paper introduces a new method for testing the flame retardant performance of textiles, namely 45 degrees burning. The method is based on the observation of the burning behavior of textiles at 45 degrees angle from the horizontal plane and can provide important information about their flame retardant performance, including flame spread tendency, burning rate, and char residue formation. This method can be applied to a wide range of textile materials and can help evaluate the effectiveness of flame retardant treatments applied to textiles accurately and reliably. Future work will focus on further optimization of this method to enhance its reproducibility and accuracy while also exploring its application in other fields such as polymer materials or composite materials where flame retardancy is crucial for material performance and safety applications
