摘要

染料本身的結構和性質，往往影響了其在水中的溶解度或分散性，然而通常溶解性較佳的染料經由染色後的展色性相對好，也因此有染整後卻不耐水洗的困擾。
　　超細聚酯纖維的缺點：1.結構細密，比表面積大，對可見光反射和散射能力強，因此造成在同濃度條件下染色時，其表觀濃度較一般聚酯纖維低；2.表面缺少反應性基團可與染料結合，容易染色不均，導致耐水洗堅牢度較差。基於上述兩點，本實驗設計將具有反應性官能基高分子應用在棉布與超細聚酯織物上，藉以強化織物深染性，及改善染色後水洗堅牢度等為主要目的，期待能夠藉由官能基的接枝改質，增加其染色效果。
　　取適當比例的Acrylic acid (AA)、Methyl acrylate (MA)及Glycidyl methacrylate (GMA)單體，使用2,2’-Azobisisobutyronitrile (AIBN)為起始劑，並使用Tripropylene glycol diacrylate (TPGDA)為架橋劑，利用自由基聚合反應原理，分別製備不同比例的架橋型丙烯酸酯共聚物。取用棉布與超細聚酯織物並含浸於上述製備好之丙烯酸酯共聚物中，乾燥後再以不同劑量電子束(electron beam)照射，使共聚物與織物表面自由基化產生接枝反應而有化學鍵結的產生；利用結構上含有胺基的染料與丙烯酸酯共聚物上的環氧基反應，使染料直接成為高分子鏈段上的一部分，間接增強染料分子與纖維結合力，進而提高其耐水洗堅牢度。

The structure and property of dyes is desided by the solubility or disperability of dyes in the water. Good solubility of dyes usually comes with good dye dispersion, not also cause the problem of poor resistance to water washing and laundering.
　　Micro-fiber polyester fabric had compact structure, high specific surface area, and strong reflection and scattering to visible light, to cause the dyeing of textile is more difficult than polyester in the same concentration；And had no function group to combine with dye, the surface concentrations of dyes absorption are higher than the internal part of fabric, so that usually out of proportion or discolor after water launder. In order to solve these problems, we focus on improve the intensity of color and resistance strength of water launder by grafting function group.
　　This research utilize suitable ratio of Acrylic acid (AA), Methyl acrylate (MA), and Glycidyl methacrylate (GMA) monomer with initiator 2,2’-Azobisisobutyronitrile (AIBN) and bridging agent Tripropylene glycol diacrylate (TPGDA) to synthesis acrylate copolymers in different monomeric concentration. After reactions, it becomes cross-linking structure and insoluble in water.
　　Take cotton and micro-fiber polyester fabric, immerses in specific ratio of acrylate copolymers. When textile dried, illuminate by different dosage of electron bean (EB). Radicalize polymer and textile surface, and bonding with each other.
　　The special amino group of dye on the structure formulate will react with the epoxy group on acrylate copolymers. Then, dye becomes part of the polymer chain and enhance the interaction between dye molecular and textile.
