从专利角度分析国内外喷气涡流纺的发展

Development of Vortex Spinning at Home and Abroad from Patent View

从专利角度,探讨了国内外喷气涡流纺的发展历程。从各个检索平台中检索出国内外关于喷气涡流纺的相关专利,并进行分析。对比了国内外专利的数量、质量以及专利申请人分布等情况,总结了国内外喷气涡流纺的发展状况、技术热点、技术质量等。认为:国外重点研究的是喷气涡流纺加捻装置、接头装置和牵伸装置等,国内重点研究的是如何提高喷气涡流纺纱质量以及通过前处理拓宽原料范围;国内关于喷气涡流纺的研究起步较晚,专利授权率和有效率较国外相关专利还有一定的差距。

The development process of vortex spinning at home and abroad was discussed from patent view. Related patents about vortex spinning at home and abroad were searched and analyzed from every search platform. Quantity, quality and applicant distribution of patent at home and abroad were compared. Development state,technology focus and quality of vortex spinning at home and abroad were summarized. It is considered that twist device,joint device and draft device of vortex spinning are researched as key points at abroad. At home key points of the study are how to improve the quality of vortex spinning yarn and how to extend the range of raw materials through pre-treating. Vortex spinning research started late at home,there are certain gaps at license and effective rate of patent comparing with related patent at abroad.
