An instrument has been designed and developed to measure the smoothness behavior of finished cotton fabrics. The instrument is based on pendulum principle. The weight (hang on string) comprises a frictionless wheel movable along arc shaped platform. The platform acts as a sample holder. When the weight is subjected to push, it swings back and forth in the platform. The amplitude of the swing reduces due to friction of the fabric. The amplitude is inversely proportional to the friction or roughness of the fabric. Various types of finished cotton fabrics are tested on the developed instrument. The results are compared with Kawabata system to verify the working of instrument. These results are also compared with the bending length and crease recovery behavior of the particular fabric sample. It is found that the lesser the bending length the more will be the smoothness. If the crease recovery angle is high, the fabric will be smoother. One way analysis of variance has been applied to find out effect of different processes on fabric surface smoothness property.

织物光滑度测试仪的研制

已经设计并开发了一种仪器来测量棉织物成品的光滑度。该仪器基于摆原理。配重（挂在弦上）包括可沿弧形平台移动的无摩擦轮。该平台充当样品架。当重物受到推压时，其在平台中来回摆动。摆动幅度由于织物的摩擦而减小。振幅与织物的摩擦或粗糙度成反比。在开发的仪器上测试了各种类型的成品棉织物。将结果与Kawabata系统进行比较以验证仪器的工作。这些结果也与特定织物样品的弯曲长度和折痕回复行为进行了比较。发现弯曲长度越小，光滑度越大。如果折痕恢复角大，则织物会更光滑。已应用一种方差分析方法来找出不同过程对织物表面光滑度特性的影响。
