自從杜邦公司研發了尼龍以來，尼龍已經廣泛運用在我們生活中，其材質特性輕薄、延伸度佳、耐磨且具有一定的防水性，在軍用以及日用方面都被大量地使用。
尼龍是由醯胺鍵連接單位的一種縮合聚合物，最常見的是尼龍6/6，是由己二胺和己二酸聚合而成的，其中醯胺鍵上的氫與氧會互相形成氫鍵，使尼龍6/6容易形成結晶，因此尼龍6/6擁有不錯的物理性質，並且能用各種方式改質進行增強；例如尼龍6/6的吸水性強，若在濕度較高的環境中使用，會影響其尺寸穩定性，導致無法用在較為精密的部件。
本論文將會對尼龍6/6進行改質，使用雙螺桿混練機進行混練，在其中添加玻璃纖維增強其機械性質，同時在其中添加吸濕性較低的尼龍6/12，以不同比例進行混練，再進行物性測試及吸濕性測試

Since DuPont synthesize nylon, nylon has been widely used in our life. Its material characteristics are light and thin, good elongation, wear resistance and a certain degree of water resistance. Therefore nylon is widely used in military and daily use.
Nylon is a condensed polymer that its units are connected by amide bond. The most common nylon is Nylon 6/6, which is formed by the polymerization of hexamethylene diamine and adipic acid, in which hydrogen and oxygen on the amide bond form hydrogen bonds with each other, makes it easier to form crystals, therefore, has better physical properties. Nylon is able to modified in various ways to enhance the property; for example, nylon 6/6 is hygroscopic. If it is used in an environment with high humidity, will affect its dimensional stability, resulting in it can not be used in more precise parts.
In this study, Nylon 6/6 will be modified by mixing Nylon 6/6, Nylon 6/12 and glass fiber with a twin-screw extruder. The glass fiber is added to enhance its mechanical properties. At the same time, nylon 6/12 is added to decrease its hygroscopicity. After mixing, will do the physical test and hygroscopicity test.
