PVA removing process is optimized by orthogonal test, and by use of analysis of variance method, factors which affect PVA removing result and the final quality of fabric are also studied. The PVA removing process is optimized. Comparing with twist woven plain fabric whose woven parameters are same to corresponding twistless fabric, properties of twistless woven fabric including breaking strength, tear strength, flex abrasion, air permeability, water vapour transmission, pilling resistance, drape, dimensional stability, wicking, and dyeing uptake are tested.

无捻纱机织物与有捻纱机织物(文中所提到的这两种织物的织物密度、纱线的号数等织造参数相同)的对比试验是本文的又一重点，本文通过对比试验，测试了织物的拉伸性能、撕破性能、顶破性能、耐磨性能、外观保持性、悬垂性、刚柔性、透气性、透水性、芯吸性能，绘出了上染速率曲线等，得到了大量的对比数据，并以数据为基础进行了分析，得出结论为：无捻纱织物具有良好的透湿、保暖、吸湿性能以及柔软的手感和较高的覆盖率，这些都证明了无捻纱机织物有良好的舒适性。

8T ball mill has new constructure inner liner with transiting round corner and uncontinuous spiral which is built by alumina corundum-based heteromorphic brick and common ceramic tiles.

8吨球磨机应用氧化铝刚玉质异形砖与普通瓷质砖砌筑成具有过渡圆角及不连续螺旋的新结构内衬，在广东某大型企业的生产线上球磨陶瓷耐磨地砖釉料，并就釉料颗粒大小及粒度分布、电耗、介质磨耗等与1.5吨球磨机进行对比，进行了实验研究。

Underhill comes to pick up a income for his lunch check, Fletch searches for a time upon his non watch-wearing wrist .
