宇航用千兆数据电缆阻抗突变与编织张力研究

面向新一代航天器的千兆数据传输应用中,作为数据传输介质的千兆数据电缆对数据传输特性有着较大的影响。为了满足宇航用千兆数据电缆高可靠性要求,对宇航用千兆数据电缆加工过程中编织张力对电缆阻抗突变的影响进行了分析,提出了编织工艺的张力一致性对电缆的阻抗稳定起到了关键的作用。采用带有时域阻抗(TDR)的网络分析仪对不同编织张力下的宇航用千兆数据电缆的差分阻抗进行了测试,测试结果表明,电缆阻抗指标与编织张力密切相关。在测试结论的支撑下,规范了宇航用千兆数据电缆编织工艺张力。为高可靠性宇航用千兆线缆传输提供了理论依据及测试试验数据。

化纤长丝在针织机上编织时摩擦性能的探讨

分析了针织机上化纤长丝与光滑的玻璃、陶瓷导纱器之间产生摩擦力的机理,提出了在针织机上解决化纤长丝与光滑的陶瓷导纱器摩擦力过大的方法,即应减少长丝与导纱器之间的实际接触面积,由此实现正常编织。

腰边罗纹毛坯幅宽的控制

分析影响腰边罗纹毛坯幅宽的主要因素,包括氨纶规格、氨纶编织张力、棉纱编织张力、牵拉卷取张力、三角压针深度、针盘与针筒之间的距离,利用这些因素综合对织机进行调整,实现了在一种规格的织机上生产几种不同规格幅宽的腰边罗纹坯布,并列举实例说明。

压电陶瓷贾卡导纱针偏移时间分析

为达到合理选用贾卡导纱针的目的,对压电陶瓷贾卡导纱针偏移特点进行分析。在此基础上通过使用动态分析三维显微系统构建实验平台,并对两种力矩的贾卡导纱针在不同编织张力条件下的偏移时间进行测试。总结出编织张力对贾卡导纱针偏移时间的影响以及两种力矩的贾卡导纱针分别适用的编织张力和最高机速范围。提出一种压电陶瓷贾卡导纱针的选配方法,并以双针床毛绒贾卡经编机的贾卡导纱针选配为例进行验证,结果表明该选配方法合理、实用。

Use of Polypropylene Non-woven as Sorbent of Oil Small

In this work, the mechanical tensile and elongation properties and the non-woven polypropylene flammability were evaluated, with variations of gratings, compared to non-woven fabrics prepared with thermo film and TNT （fabric non-fabric）, for applications such as geotextile sorption of oil spills. The results showed high values of tensile strength for non-woven fabric prepared for application as geotextile, improving the mechanical properties of rupture.

Tensile Property of Bi-axial Warp Knitted Structure

The tensile property of bi-axial warp knitted fabrics is tested and compared with that of the plain weave fabric. The results show that there are obvious differences between the tensile property of a bi-axial warp knitted fabric and that of a plain weave fabric.The former can give fuller play to the property of a high modulus yarn than the latter. The tensile strength of a bi-axial warp knitted fabric is linear with the number of yarns in the direction of force.
