碩士 === 逢甲大學 === 紡織工程所 === 94 === In our research, we try to use polycarboxylic acid (PCA) / nano-silver-ion compound as the non-formaldehyde / anti-bacterial crease-resist finishing agents of cotton. We evaluated the duration of the different type of binders; the content of the nano-silver-ion; the different type of light source; the different periods of the time; the different type of polycarboxylic acids and the different DMDHEU concentrations in our experiments. The dry wrinkle recovery angle, the durable press, the strength, the whiteness and surfacial were all enhanced as the mount of the agents increased. The crease-resist, anti-bacterial activity and duration are also improved after the finishing process. According to the experimental results, we find that, first, the dry wrinkle recovery angle and the durable press increased as the silver-ion content, lighting time, PCA and DMDHEU concentration increased. On the other hand, PCA-treated samples showed more crease-resist after UV irradiation 60 minutes, than DMHEU. The cotton with the PU binder shows a good anti-bacterial activity after 20 circles of washes. With washing times increased more than 20 circles, anti-bacterial activity had a reduced tendency. The strength, and whiteness were obviously decreased as the PCA and DMDHEU concentration increased, and so were the lighting time. After treatment with PCA, the reducing in strength is about 25%. It is better than the traditional DMDHEU reagent. With silicone binder adding, we find the surfacials is better than other kinds of binders. And the result of FTIR is the firm evidence that the cotton treated with PCA are formed esterification crosslinking. Therefore, we concluded the physical properties of cotton treated with PCA are much better than treated with DMDHEU. And then polycarboxylic acids are really milder reagent than DMDHEU when they are used in cotton process.
