在分析复合织物组分形态的基础上，研究了针刺深度和针刺密度对复合织物性能的影响。
Based on morphology analysis of composite fabric, the effects of needle punching depth and density on properties of composite fabric were investigated.
介绍了针刺法非织造有针刺密度的计算公式及其变换，以及计算尺的使用，以利于生产者方便应用。
The calculation and converting of the formula for punching density of needle punching nonwovens and the usage of the slide rule are introduced, to be favourable for producers to use.
我们首先要探讨的是针刺所产生的电流及其密度和强度的问题。
We will first explore the acupuncture is generated by the current and density and intensity of the problem.
不同体积密度、不同厚度的针刺毯为用户提供了宽阔的选材范围，以获得最佳隔热结构和效益。
Our needled blanket has various density and thickness so that our client can have many choices, which will bring the perfect insulating framework and profit.
静力牵张组在M线及M线两侧的标记结果与针刺组一致。仅在M线两侧以外区域牵张腿与运动对照腿之间标记密度的差异没有统计学意义。
Similar results were observed in the static stretch group, but the difference of label density between the control and the static stretch in the areas beyond M-line was nonsignificant.
芳砜纶针刺非织造布经过硫酸溶液处理后，纤维断裂强度略有下降，纤维线密度减小； 非织造布的尺寸稳定性很好，而其断裂强力却有明显增加。
With the treatment of PSA needle-punched nonwoven fabric in the sulphuric acid solution, the broken strength of PSA fiber decreases slightly and the fineness of PSA fiber gets smaller.
