高强低伸型涤纶工业丝总拉伸倍率与断裂强度关系分析数据

在涤纶工业丝生产过程中，总拉伸倍率会对涤纶工业丝产品的断裂强度产生
重大影响，通过采取不同的总拉伸倍率设置对产品断裂强度指标进行测试，经计算建立总拉伸倍率与断裂强度的对应关系，进而可以研究各级总拉伸倍率对断裂强度的影响规律。根据日常实际试验积累，获得不同总拉伸倍率工艺下的断裂强度数据；二、数据分析：总拉伸倍率作为因变量（X），断裂强度为自变量（Y）, 通过fit（）函数对X、Y的值进行模型训练，最后拟合形成总拉伸倍率与断裂强度关系的多项式方程模型：Y=b1X +b2X2 +b3X3+b4X4 +e。三、数据应用：利用上述规律，可以通过代入不同总拉伸倍率数值（X）计算得到Y值，即断裂强度，进而提升工艺开发效率，指导纺丝工艺调整。

In the production process of polyester industrial yarns, the total draw ratio exerts a significant impact on the breaking strength of the final products. By testing the breaking strength indicators with different total draw ratio settings and establishing the corresponding relationship between total draw ratio and breaking strength via calculation, the influence rules of various total draw ratio levels on breaking strength can be further investigated. Breaking strength data under different total draw ratio processes are obtained based on accumulated daily practical experiments.
2. Data Analysis: Treat total draw ratio as the dependent variable (X) and breaking strength as the independent variable (Y). Train the model using the X and Y datasets through the fit() function, and finally fit a polynomial equation model that describes the relationship between total draw ratio and breaking strength: $Y = b_1X + b_2X^2 + b_3X^3 + b_4X^4 + e$.
3. Data Application: By leveraging the aforementioned rules, the Y value (i.e., breaking strength) can be calculated by substituting different total draw ratio values (X). This helps improve the efficiency of process development and guide the adjustment of spinning processes.
