摘要

本研究針對TPU／EVA混摻系統之共押出熱熔膠薄膜之材料組成、加工參數及貼合性能進行探討，用以達成紡織業無車縫、無溶劑之高效環保要求之貼合膜。實驗上經由DSC熱分析、流變行為分析選定最適化之TPU／EVA加工參數，並經由共押出膜之結構設計，產出熱熔膠單層膜和具有TPU基材層及熱熔膠層之雙層複合膜。經由力學性能、貼合之剝離特性、耐水解性及彈性回復率，綜合評析而獲致最佳之組成膠膜材料及加工參數。

In this research, the composition, processing parameters, and the ability of lamination in TPU/EVA blends system co-extrusion hot melt adhesive films were investigated, which were used to produce high-efficiency environmental-friendly sewing free and solvent free lamination film for textile. In the experiment, the TPU/EVA blends were analyzed by Differential Scanning Calorimetry (DSC) and Cone/Plate Rheometer to determine the best processing parameters. Through designing the structure of co-extrusion film, we got the hot melt single-layer adhesive film and the double-layers film consisting of TPU base-layer and hot melt single-layer film. Analyzed through the tests of mechanical properties, peeling properties of lamination, resistance to water, and elasticity recovery, the best composition of adhesive film and processing parameters were generalized.
