About Qingya Paper 12 Methods for Fiber Identification (3) --- Melting Point Method user manual | Qingya Paper
12 Methods for Fiber Identification (3) --- Melting Point Method:
Different melting points of various chemical fibers can also be used for fiber identification. For example, the melting points of nylon 6 and nylon 66 are different, with the former being 216°C and the latter 244°C. The melting point of chemical fibers can be determined by observing the temperature at which the fibers lose birefringence under a polarized light microscope equipped with a heated stage and thermometer. The melting point method is suitable for identifying certain synthetic fibers that have a distinct melting point.

12 kinds of fiber identification methods (2) -- combustion method
One of the common methods for identifying natural fibers. Because the chemical composition of the fibers is different, the combustion characteristics are also different. Cellulosic fibers and protein fibers can be distinguished based on how easily the fibers burn, whether they are thermoplastic, the odor produced during combustion, and the characteristics of the ashes after combustion. Cellulose fibers such as cotton, h**p and viscose burn quickly in contact with the flame, and continue to burn after leaving the flame, with the smell of burning paper, leaving a small amount of soft gray ash after burning; Protein fibers such as wool and silk burn slowly when they come into contact with the flame, and continue to burn slowly after leaving the flame, with a smell of burning feathers, leaving black brittle ash after burning.
