[Chemical Knowledge]：Detection Methods and Analysis Techniques of Spandex

Spandex detection method: technology and precision

Spandex, as a synthetic fiber with excellent elasticity and durability, plays an important role in the modern textile industry. In order to ensure the quality and safety of spandex products, it is very important to carry out comprehensive and accurate detection. At present, with the progress of science and technology and the continuous innovation of detection technology, the detection method of spandex is also increasingly rich and accurate.

Infrared spectroscopy: Infrared spectroscopy is a commonly used spandex detection method. By analyzing the absorption characteristics of spandex samples in the infrared band, its composition and structure can be determined. The method is non-destructive, rapid and accurate, and is suitable for the quality detection and analysis of spandex fibers, spinning materials and finished products.

Raman spectroscopy: Raman spectroscopy is an analytical technique based on the light scattering effect, which can be used to detect the crystal morphology, molecular structure and impurity content in spandex. Compared with the traditional detection method, Raman spectroscopy has the advantages of simple operation, no sample pretreatment and high sensitivity, which is suitable for in-situ detection and characterization of spandex materials.

Thermal analysis method: Thermal analysis method includes thermal reanalysis (TGA), differential thermal analysis (DSC) and other techniques, by analyzing the thermal behavior of spandex samples at different temperatures, it can determine its thermal stability, thermal decomposition characteristics and crystal transformation and other parameters. This information is of great significance for evaluating the processing performance and the adaptability of the use environment of spandex fiber.

Scanning electron microscope (SEM):SEM is a high-resolution microscope that can observe and analyze the surface morphology and microstructure of spandex fibers. SEM technology can detect the surface defects of spandex fiber, fiber fracture and the interface bonding between fiber and other materials, which provides an important reference for fiber preparation process and product design.

The comprehensive use of the above detection methods can comprehensively and accurately evaluate the quality index of spandex products, and provide technical support and quality control guarantee for textile manufacturers. With the continuous innovation and improvement of testing technology, it is believed that the quality of spandex products will be further improved, injecting new vitality into the development of the textile industry.

Spandex Analysis Technology: Application Prospects and Challenges
