为促进新型纺纱技术的创新，本文检索了转杯纺、摩擦纺、喷气纺、涡流纺4种典型新型纺纱技术的中国发明专利、实用新型专利和外观设计专利；统计分析了相关专利的数量变化过程、专利的技术广度和技术集中度，并对相关专利的主要申请人和发明人进行了分析。指出如能及时掌握主要专利申请人和发明人的技术思路，则可在同类产品的研发过程中避免发生知识产权的冲突，并制订出自己的专利战略；同时，根据分析可知，摩擦纺和喷气纺的研究热度正在衰减，预示其发展前景较差；目前转杯纺的研究已成为热点，但发展前景不如涡流纺。%In order to promote the innovation of new spinning technology ,the Chinese invention patent , utility model patents ,and exterior design patents about rotor spinning ,friction spinning ,jet spinning , and vortex spinning are retrieved .The number of relevant patent change process ,technical breadth and concentration are statistically analyzed .And the related principal applicant and inventor of patent are also analyzed .It is pointed out that if the technology of patent applicant and inventor are grasped ,the conflict of similar products research and development and intellectual property rights should be avoided ,and the patent strategy are worked out by themselves .According to the analysis ,friction spinning and jet spin‐ning studies gradually decreased ,indicating that its development prospect is poorer .T he current research of rotor spinning has become a hot research area ,but its development prospect not as good as the vortex spinning .
