THE SCROOPING TREATMENT OF POLYESTER SILKLIKE FIBERS

In this paper the mechanism producing scrooping sound has been discussedtheoretically.It has been recognized that the continuous stick-slip vibrationhaving a certain period and the bigger △E(△E——enery released by stick-slipvibration at one time)are the requisite and surfficient conditions producingscrooping sound.For fiber sample,its surface properties and internal structureare two principal factors influencing scrooping sound. Considering the surface properties of polyester fiber after scrooping treatmentare the synthetic reflection of the properties used treatment reagents and thesurface properties of the fiber,how selecting proper reagents for scroopingtreatment would be the key factor influencing the scrooping effect.Sometreatment solutions having better scrooping effect have been obtained in the paper. In order to cause better scrooping effect,not only the treatment reagent andsurface properties of the fiber,but also the internal structure of the fiber must beconsidered,It has been shown in

真丝绸摩擦振动声响特征分析

本文主要对丝织物间的摩擦振动声进行了初步的研究，并试图找出真丝绸特有的丝鸣特征。将不同原料，经过不同处理的两块织物在一定条件下摩擦发声，将摩擦声进行频谱分析和波形分析。根据实验结果可得，经酸处理的真丝织物具有明显的倍频效应，且频率在６～８ＫＨｚ问的振动亦较化纤织物为多。
