| 摘 要： | 以UHMWPE干法初生丝为原料进行三级连续热拉伸。参考均匀设计研究了拉伸过程中的各级温度、拉伸比、进丝速度共7个影响因素对产品丝的强度影响,利用二次多项式逐步回归优化了工艺条件,并用留一法计算PRESS对模型的预报功能进行验证。工艺优化后的纤维平均强度可达33.47cN/dtex,达到了优化的目的。

| Abstract: | A three-stage continuous hot drawing experiment was carried out on as-spun samples whit fabricated by dry spinning method. The influence of seven factors in drawing process on the strength of fibers was studied by using the uniform design and quadratic polynomial stepwise regression method, and cross-validation models was used to calculate the predicted residual error sum of squares (PRESS) statistic. The average fiber strength of the optimized process could reach 33.47 cN/dtex. |
