兼具雙疏及抗紫外線功能之低氟加工劑的合成與應用研究

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PDMS (聚二甲基矽氧烷)、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。並將乳液作性質與應用的探討。經實驗結果得知，當PDMS / LMA / MMA之重量比為1:1:1時，共聚物具有良好之疏水及疏油效果。其次乳液的固含量會隨著GPTMS的量增加而有先增後減的趨勢。乳液的粒徑會隨著GPTMS添加量的增加，粒徑會有先減小後增大的趨勢，乳液的表面電位則會先增大後減小，並可使乳液之起始溫度提高大約5℃左右。將乳液應用於加工布方面，過多的GPTMS並不能顯著提升加工布對水和油的接觸角，經由SEM對整理之棉織物進行微觀形貌觀察的結果，G1.0乳液可在纖維表面形成一層均勻的疏水膜，而使處理後棉織物撥水撥油接觸角分別為137o、113o，且在乳液中添加少量的GPTMS就可以明顯提高加工布之抗紫外線的效果。G1.0具有使染色織物抗紫外線與色澤增深的效果，且經過皂洗10次之後染色布仍比未加工之染色布深。自製乳液G1.0與市售Ya乳液比較，皆具賦予染色織物優良之撥水撥油性能、抗紫外線與增加色澤之效果，但由於G1.0含氟量為12%較Ya的35%，大約減少了66%，故在接觸角方面，B1.0會比BYa稍差，但在抗紫外線及增深效果上，B1.0反而較佳。

This study utilizes emulsion polymerization to synthesize multiple-function fabrics to organize finishing agents (the so-called emulsion), which is the emulsion of organic silicone acrylates that PDMS / 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 emulsion. The following results were obtained through test: when the weight ratio of PDMS / LMA / MMA is 1:1:1, the copolymer has good water and oil repellency effect. With the increase of the amount of GPTMS, the solid content of emulsion has the trend: first increased then decreased. The particle size of emulsion increased with the increase of the addition amount of GPTMS, particle size would have the trend: first decreased then increased. The surface potential of emulsion would first increase then decrease, and the initial decomposition temperature of the emulsion will increase for about 5℃. When the emulsion is applied in the respect of processed-fabric, too much GPTMS can not obviously increase the water and oil contact angle of processed-fabric, through SEM microcosmic topography observation on finished cotton fabric, the following results were obtained: G1.0 can form a uniform layer of water repellency membrane on fiber surface, make the water and oil repellency contact angles of treated cotton fabric become 137 °and 113 °, and adding a bit of GPTMS could obviously enhance the anti-UV effect. G1.0 could make dyed textile have the effect 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 emulsion G1.0 and on-market Ya emulsion, both two has the capability of water and oil repellency, effects of anti UV and color darkening, but as G1.0 contains 12% fluorine, Ya contains 35% fluorine, about reducing 66%, so in the respect of contact angle, B1.0 is a little less than BYa, but in the respect of anti UV and color deepening effect, B1.0 is better.
