高能辐照下聚酯纤维的聚集态结构变化及防熔滴性能研究

Melt dripping of polyester fibers at time of encountering heat limits its use in the field of flame retardant clothing. Changing the linear macromolecular to three dimensional network is the effective method to hinder the melt dripping and irradiation cross-links is the best way to produce the network. Owing to the complexity of irradiation cross-linking on the structure and property of fiber, there are still many key theory and technology subjects which need to be investigated. The structure and property of polyester fiber under different irradiation conditions will be studied in this project, and its changing rule will be the fundamental data for textile material. Research on the relationship between aggregation structure and irradiation effect, anti-dripping property and the analysis of factor influencing anti-dripping performance will guide the engineering problem. The building of the irradiation cross-linking model of polyester fiber will provide the performance-based design with the theoretical foundation. The research results will not only have the higher academic value, but also promote the development of anti-dripping fibers of our country, improve the technological level and international competition of the flame-retardant products.

聚酯纤维如PET、PBT等的遇热熔融滴落是限制其在服用阻燃纺织品领域使用的主要问题。将其线性大分子结构转变成三维网状结构是实现防熔滴的核心和关键。辐照交联技术则是产生三维网状结构的最好方法。由于高能辐照对纺织纤维结构和性能影响的复杂性，因此防熔滴加工中尚有不少关键理论和技术问题需要深入研究。本项目将研究不同辐照条件下聚酯纤维的结构和性能变化，揭示高能辐照对聚酯纤维结构和性能影响的规律，可作为纺织材料学的基础性数据；通过对纤维聚集态结构与辐照效应、防熔滴性能关系的研究，深入分析影响防熔滴性能的因素，为工程提出理论指导；建立完善的聚酯纤维辐照交联模型，更好地为材料的辐照性能化设计提供理论依据。研究成果在具有较高学术价值的同时，可进一步推动我国阻燃防熔滴纤维的开发，提升行业技术水平和产品的国际竞争力。
