聚氨酯(簡稱PU)，主鏈中含有氨基甲酸酯單元之高分子。此類高分子材料廣泛用於黏合劑和各種塑料泡棉。本實驗即是將發泡劑和固化劑以1:1之等比例混合，並將其分成兩部份分別添加空心微珠和蛭石各0、1、3、5 wt%之比例製得各比例添加物之PU發泡板材。進而對板材進行衝擊、頂破、回彈、實體表觀測試。測試發現，在吸收衝擊方面相較於添加了空心微珠之樣本，添加蛭石的發泡材樣本有較好的緩衝性能，在頂破方面之最大強力亦然，但差異不大，而回彈性能方面添加了空心微珠的樣本顯然比添加蛭石來得佳，因此由實驗可知添加料會增強PU發泡材結構之緩衝性質，且添加蛭石比空心微珠有更好的提升效果。

In this paper, the wool fibers were treated by different concentration sodium hydroxide. It can be seen from experiments results that the diameter of wool increased with the increasing of treatment time but the diameter treaded to be stable after a certain time. The diameter of wool increased linear with the increasing concentration of sodium hydroxide. At the same time, the diameter of treated wool fiber with NaOH solution shrinkaged and closed to dry wool diameter by acid neutralization. These experiment data will provide a theoretical basis for the processing of wool fibers.

牽伸過程是纖維生產中的關鍵環節，其拉伸效果通過牽伸率來衡量。牽伸率主要由各牽伸環節內各個捲繞輥的相對轉速決定。牽伸率直接影響到最終製成的纖維原絲及成品的性能。針對牽伸率在纖維生產過程中的重要性，提出了基於SVR-ARX模型的纖維牽伸率預測方法，得出了纖維牽伸率的預測結果。實驗結果表明，SVM-ARX建立的回歸預測模型比SVR建立的回歸預測模型預測精度高。

The fiber stretching process plays a key role in the process of fiber production and its effects is measured by the stretching ratio. The stretching ratio is determined by the relative speed of the winding roller. The stretching ratio is impact on the performance of the final fiber filament and production directly. Focused on the importance of the stretching ratio, the SVR-ARX predictive model for the fiber stretching rate based on existing industry data is proposed. Simulations results demonstrate that the proposed SVR-ARX method can increase the predict results than the traditional SVR method.
