项目摘要

High energy treatments of polymer substrate such as ultraviolet light irradiation, electron beam irradiation, low temperature plasma treatment, sputter etching treatment, etc.have been widely applied as practical techniques to modify the surface characteristics of the medical polymers. In the field of textile processing, these treatments have still been under investigation because of the difficulties in continuous processing large and wide textile substrates.In this study, applications of these high energy treatments to the dyeing process of the textiles have been investigated. The surface modification by the high energy treatments could be expected to alter the dyeability of the polymer substrates, and hence, if one could apply the patterned treatments on the textile substrates, patterned dyeings could be obtained by the subsequent simple exhaustion dyeing.From the results of the study of the cooperative project with University of Leeds in United Kingdom, we have obtained favorable results that the high energy treatments can be practically applicable to obtain patterned dyeings by the simple exhaustion dyeing. High energy treatments on the textile substrates have been found to oxidize the surface of the textile substrates and to alter the dyeability. The mechanisms of the alternation of the dyeability by the high energy treatments could be attributed to the alternation of the affinity between the dyes and the treated substrates that were brought about by the modified surface characteristics of the substrates.The alternation of the dyeability by the treatments could be found in almost all kinds of textile substrates. The technology of the high energy treatments, therefore, could be concluded to be applicable to obtain patterned dyeing not only of textiles of natural fibers but also of that of synthesized fibers.This research could be expected to provide valuable information to develop a new technology for dyeing industries.

聚合物基底的高能处理如紫外光照射、电子束照射、低温等离子体处理、溅射蚀刻处理等已被广泛应用作为改性医用聚合物表面特性的实用技术。在纺织品加工领域，由于连续加工大而宽的纺织品基底的困难，这些处理仍然在研究中。在本研究中，这些高能处理在纺织品染色过程中的应用进行了研究。通过高能处理的表面改性可以预期改变聚合物基材的可染性，因此，如果可以在纺织品基材上施加图案化处理，则可以通过随后的简单浸染获得图案化染色。从与英国利兹大学的合作项目的研究结果来看，我们已经获得了有利的结果，即高能处理可以实际应用于通过简单的吸尽染色获得图案染色。已经发现对纺织品基底的高能处理会氧化纺织品基底的表面并改变可染性。高能处理改变织物染色性能的机理可归结为改变被处理织物的表面特性，改变染料与被处理织物之间的亲合力，这种改变几乎存在于所有的织物上。因此，高能处理技术不仅适用于天然纤维织物的图案化染色，也适用于合成纤维织物的图案化染色，为开发新的染色技术提供了有价值的信息。
