摘要

本文採用乳液聚合法合成多功能性織物整理加工劑(統稱乳液)，即FMA(全氟烷基丙烯酸酯)、MMA(甲基丙烯酸甲酯)、LMA(十二烷基甲基丙烯酸甲酯)和GPTMS(縮水甘油氧基丙基三甲氧基矽烷)開環合成有機矽丙烯酸酯乳液，確定了最佳合成條件，並探討乳液之性質及應用的影響。經實驗結果知，随着FMA重量之增加，乳液粒徑隨之增大，乳液固含量隨之減小，另乳化劑CTAB(Cetyltrimethyl Ammonium Brombide)重量增加，乳液粒徑隨之減小，乳液表面電位卻增大。其次乳液的粒徑隨起始劑V-50(2,2’-Azobis(2-aminopropane) dihydrochloride)重量增加有先減小後增大的趨勢，乳液表面電位卻隨之減小，當乳液中加入GPTMS時，隨其用量之增加，乳液粒徑有先減小後增大的趨勢，乳液表面電位卻隨之減小，且可將乳液之起始分解溫度提高15∼20℃左右，聚合物的耐熱性增強。將乳液應用於棉織物方面，過多的FMA單體不能顯著提高加工布對水和油的接觸角，另CTAB重量增加，經該乳液加工後之加工布接觸角隨之增加，其次當織物各別經起始劑APS(Ammonium Persulfate)與V-50所製得之乳液加工後，V-50所製得之乳液其撥水撥油性能較APS所製得之乳液優良。在乳液中加入少量的GPTMS就能顯著提高加工布之抗紫外線效果與撥水撥油的接觸角。經SEM對整理之棉纖維織物微觀形貌觀察的結果表明，G10可在纖維表面形成一層均勻疏水膜，而使整理後棉織物原胚撥水撥油接觸角分別為158°、126°，且具有抗紫外線之效果。G10具有使染色織物抗紫外線與顏色增深的效果，且水洗10次後之染色布仍比未加工之染色布更深。自製乳液G10與市售TFT乳液比較，皆有賦予染色織物優良之撥水撥油性能、抗紫外光與色深之效果，但G10優於TFT。

This study utilizes emulsion polymerization to synthesize multiple-function fabrics to organize finishing agents (the so-called lotion), which is the lotion of organic silicone acrylates that FMA, MMA, LMA and GPTMS ring-open and synthesize. This study also confirms the optimal conditions of synthesis and further explores the impact of the nature and applications of lotion. First, it is known from the results of the experiments, with the increase of the weight of FMA, the particle diameter of the lotion increases while the solid content of lotion decreases accordingly. In addition, CTAB (Cetyltrimethyl Ammonium Brombide) increases in its weight, the particle diameter of lotion decreases while the surface potential increases. Secondly, the particle diameter appears to decreasing and then increasing as the weight of the initiator V-50 (2,2’-Azobis(2-aminopropane) dihydrochloride) increases, and the surface potential of lotion decreases accordingly. When GPTMS is added to lotion, with the increase of its usage, the particle diameter of lotion tends to decrease first and then increase, but the surface potential will decrease, and the initial decomposition temperature of the lotion will increase for about 15∼20℃, and the heat resistance will be improved. In the aspect of the application of lotion to textile, the excessive FMA monomer could not obviously enhance the contact angle to water and oil for processed fabrics. In addition, with the weight of CTAB increases, the contact angle of processed fabrics increase by being processed by lotion. Secondly, when the fabrics separately being processed by the lotion made by APS (Ammonium Persulfate) and V-50, the water and oil repellency from the lotion made by V-50 is better than that by APS. By adding a bit of GPTMS could obviously enhance the anti UV effect and the contact angle of water and oil repellency. The result to the micro observation of the arranging cotton fabric indicates, G10 could evenly form an hydrophobic membrane on the surface of the fiber, making water and oil repellency contact angle from the original embryo of the arranged cotton fabric 158° and 126° respectively with the effect of anti-UV. G10 could make dyed textile have the effects of anti-UV and darkening colors. The dyed fabric washed 10 times by water is still darker than the unprocessed dyed fabric. Comparing the self-made lotion G10 and on-market TFT lotion, both two has the capability of water and oil repellency, effects of anti UV and color darkening, but G10 is better than TFT.
