How to improve the rigidity advantage of my10 series pbt for filament spinning

Material modification is an important way to improve the rigidity of MY10 series PBT (polybutylene terephthalate). The rigidity of the material can be significantly improved by introducing rigidity enhancers such as glass fiber, carbon fiber or inorganic nanoparticles. These enhancers form a three-dimensional network structure in the MY10 series PBT matrix, which restricts the free movement of the molecular chain, thereby effectively improving the overall rigidity of the material. It is worth emphasizing that the type, content and dispersion state of the enhancer have a significant impact on the effect of rigidity improvement. Therefore, during the modification process, the amount of enhancer added and its dispersion process must be accurately controlled to ensure that while improving the rigidity, it does not have a negative impact on other properties of the material (such as toughness and processing performance).

The optimization of the spinning process also plays an important role in improving the rigidity of MY10 series PBT. During the spinning process, by adjusting the process parameters such as spinning temperature, stretch ratio and cooling rate, the crystallinity and molecular orientation of MY10 series PBT can be significantly affected, thereby affecting its rigidity. Higher spinning temperature and appropriate stretch ratio help the orderly arrangement and crystallization of MY10 series PBT molecules, thereby improving the rigidity of the material. At the same time, a reasonable cooling rate can effectively avoid excessive thermal stress in the material during the spinning process, thereby ensuring the dimensional stability and surface quality of the product. Therefore, in the spinning process design, it is necessary to comprehensively consider the material properties, product requirements and equipment conditions to determine the optimal spinning parameters.

Post-processing strengthening is another effective means to improve the rigidity of MY10 series PBT. Through post-processing processes such as heat treatment, stretching or compression, the crystallinity and molecular orientation of MY10 series PBT can be further improved, thereby improving its rigidity. During the heat treatment process, appropriate temperature and treatment time can promote the rearrangement and crystallization of MY10 series PBT molecules, making the material denser and harder. Stretching or compression treatment, by applying external force, makes the MY10 series PBT molecular chains arranged in a specific direction to form a more ordered structure, thereby improving the rigidity and strength of the material. However, post-processing strengthening must be carried out under the premise of ensuring that other properties of the material are not damaged, so it is necessary to strictly control the treatment conditions and process parameters.
