本研究皆在提升聚丙烯針織物之染色性。以不同電漿條件、交鏈劑濃度、丙烯醯胺（Acrylamid，簡稱AAm）單體濃度、UV光照射時間處理聚丙烯織物。以電漿使聚丙烯針織布表面產生物理性的刻蝕和化學性的極性基來提升其親水性和藥劑吸附性，並利用電漿後產生的過氧化物誘導丙烯醯胺單體進行UV光接枝共聚合，而增加染著之席位以改善其染色性，提升聚丙烯針織布產品應用範圍及附加價值。由實驗結果得知，電漿功率及時間的提高對接枝率有增加效果，且丙烯醯胺單體濃度增加，UV光照時間增長及適度添加交鏈劑有助於單體的接枝率及K/S值的提升，其親水性經氬氣電漿及UV光接枝改質後有明顯改善，但纖維強力會隨電漿時間、瓦數的增加而下降。藉由掃描式電子顯微鏡觀察到纖維表面呈現蝕刻的現象，但UV光接枝改質後，可減少纖維強力之損失，另外經丙烯醯胺接枝改質的聚丙烯織物，確實可利用反應性染料進行低溫染色之上色效果。
This study is to enhance the reactive dyeing properties of polypropylene fabrics. The effect of different plasma conditions, cross-linking agent and AAm monomer concentration and UV light exposure time on hydrophilicity and dyeability of polypropylene fabrics were researched. The dye sites of polypropylene fibers (abbre.P.P.) grafted with acrylanide by UV-induced polymerization were increased. In addition, both add-value and application of fabrics were enhanced too. From results shown that the graft ratio of polypropylene fabrics increased with increase of plasma power and treating. In addition, the K/S value was enhanced by inereasing AAm monomer concentration and UV irradiation time and adding of cross linking agent. The hydrophilicity of P.P. was improved by plasma treatment and AArn modification. The mechanical strength of PP. fiber decreased with increasing plasma treating power and time, and increased by graft modification. On the other hand, the low temperature reactive dyeing effect of PP. fabrics grafted with AAm substantially were obtained by the method.
