携纱器是三维织机织边机构中的核心部件,起到存储纱线、控制纱线张紧力的作用。设计出一种具有双涡卷弹簧、双线圈储纱装置的携纱器,配合梭形结构,在保证体积小巧的同时,极大地增加了携纱器的纱线张紧力与储纱量。携纱器的纱线穿梭路径采用上下环形绕线与中部穿梭固定环相结合的穿线模式,可以减少纱线与纱线筒之间的摩擦力。同时,下路固定环的加入,有效地减少了纱线的自缠绕问题。

Stiffness-tunable biomaterials provide a good extracellular matrix environment for axon growth and regeneration

Neural Regeneration Research 2025年第5期20卷 1364-1376页

Neuronal growth, extension, branching, and formation of neural networks are markedly influenced by the extracellular matrix—a complex network composed of proteins and carbohydrates secreted by cells. In addition to providing physical support for cells, the extracellular matrix also conveys critical mechanical stiffness cues. During the development of the nervous system, extracellular matrix stiffness plays a central role in guiding neuronal growth, particularly in the context of axonal extension, which is crucial for the formation of neural networks. In neural tissue engineering, manipulation of biomaterial stiffness is a promising strategy to provide a permissive environment for the repair and regeneration of injured nervous tissue. Recent research has fine-tuned synthetic biomaterials to fabricate scaffolds that closely replicate the stiffness profiles observed in the nervous system. In this review, we highlight the molecular mechanisms by which extracellular matrix stiffness regulates axonal growth and regeneration. We highlight the progress made in the development of stiffness-tunable biomaterials to emulate in vivo extracellular matrix environments, with an emphasis on their application in neural repair and regeneration, along with a discussion of the current limitations and future prospects. The exploration and optimization of the stiffness-tunable biomaterials has the potential to markedly advance the development of neural tissue engineering.
